Computers

Before the widespread use of computers, managers could not make full use of large amounts of valuable information about a company's activities.The information either reached managers too late or was too expensive to be used.Today, managers are facing a wide range of data processing and information instruments.In place of a few financial controls, managers can draw on computer-based information systems to control activities in every area of their company.On any kinds of performance measures, the information provided by these systems helps managers compare standards with actual results, find out problems, and take corrective action before it is too late to make changes.The introduction of computerized information systems has sharply changed management control in many companies.Even a neighborhood shopkeeper may now use computers to control sales, billing, and other activities.In large companies, electronic data processing systems monitor entire projects and sets of operations.Now, there are about 24 million microcomputers in use in the United States —— one for every 10 citizens.It is estimated that by 1996, 61 percent of American managers will be using some sort of electronic work station.In order for managers to be sure that the computer-based information they are receiving is accurate, they need to understand how computers work.However, in most cases they do not need to learn how to program computers.Rather, managers should understand how computerized information systems work;how they are developed;their limitations and costs;and the manner in which information systems may be used.Such an understanding is not difficult to achieve.One research found that business firms were more successful in teaching basic information about computers to business graduates than they were in teaching business subjects to computer science graduates.Today, conventional financial controls are still exercised in some minor areas such as billing and vocational training.A Right B Wrong C Not mentioned It is unnecessary for a neighborhood baker to use a computer in his shop

A Right B Wrong C Not mentioned At present about 10% of American citizens possess a microcomputer.A Right B Wrong C Not mentioned One thing that managers do not have to understand is how computers work.A Right B Wrong C Not mentioned In some cases managers have to learn how to write programs so as to work out computerized information systems that suit their own companies best.A Right B Wrong C Not mentioned Computerized firms would rather employ business graduates than computer science graduates because it is easier to train the former into qualified employees.A Right B Wrong C Not mentioned

LED Lighting

An accidental discovery announced recently has taken LED lighting to a new level, suggesting it could soon offer a cheaper, longer-lasting alternative to the traditional light bulb.The breakthrough adds to a growing trend that is likely to eventually make Thomas Edison‟s bright invention1 obsolete.LEDs are already used in traffic lights, flashlights, and architectural lighting.They are flexible and operate less expensively than traditional lighting.Michael Bowers, a graduate student at Vanderbilt University, was just trying to make really small quantum dots, which are crystals generally only a few nanometers big.Quantum dots contain anywhere from 100 to 1,000 electrons.They‟re easily excited bundles of energy, and the smaller they are, the more excited they get.Each dot in Bower‟s particular batch was exceptionally small, containing only 33 or 34 pairs of atoms.When you shine a light on quantum dots or apply electricity to them, they react by producing their own light, normally a bright, vibrant color.But when Bowers shined a laser on his batch of dots, something unexpected happened.He was surprised when a white glow covered the table.The quantum dots were supposed to emit blue light4, but instead they were giving off a beautiful white glow.Then Bowers and another student got the idea to stir the dots into polyurethane and coat a blue LED light bulb with the mix.The lumpy bulb wasn‟t pretty, but it produced white light similar to a regular light bulb.LEDs produce twice as much light as a regular 60 watt bulb and burn for over 50.000 hours.The Department

of Energy estimates LED lighting could reduce U.S.energy consumption for lighting by 29 percent by 2025.LEDs don‟t emit heat, so they‟re also more energy efficient.And they‟re much harder to break.Quantum dot mixtures could be painted on just about anything and electrically excited to produce a rainbow of colors t including white.The main light source of the future will almost surely not be a bulb.It might be a table, a wall, or even a fork.23.Paragraph 1_____

四、阅读理解。下面有3篇短文，每篇短文后有5道题。请根据短文内容，为每题确定1个最佳选项。

第一篇

Eat to Live

A meager diet may give you health and long life, but it‟s not much fun — and it might not even be necessary.We may be able to hang on to most of that youthful vigor even if we don‟t start to diet until old age.Stephen Spindler and his colleagues from the University of California at Riverside have found that some of an elderly mouse‟s liver genes can he made to behave as they did when the mouse was young simply by limiting its food for four weeks.The genetic rejuvenation won‟t reverse other damage caused by time for the mouse, but could help its liver metabolize drugs or get rid of toxins.Spindlers team fed three mice a normal diet for their whole lives, and fed another three on half-rations.Three more mice were switched from the normal diet to half-feed for a month when they were 34 months old — equivalent to about 70 human years.The researchers checked the activity of 11, 000 genes from the mouse livers, and found that 46 changed with age in the normally fed mice.The changes were associated with things like inflammation and free radical production — probably bad news for mouse health.In the mice that had dieted nil their lives, 27 of those 46 genes continued to behave like young genes.But the most surprising finding was that the mice that only started dieting in old age also benefited from 70 per cent of these gene changes.“This is the first indication that these effects kick in pretty quickly.” say Huber Warner from the National Institute on Aging near Washington D.C.No one yet knows if calorie restriction works in people as it does in mice, but Spindler is hopeful.“There‟s attracting and tempting evidence out there that it will work,” he says.If it does work in people, there might be good reasons for rejuvenating the liver.As we get older, our bodies are less efficient at metabolizing drugs, for example.A brief period of time of dieting, says Spindler, could be enough to make sure a drug is effective.But Spindler isn‟t sure the trade-off is worth it.“The mice get less disease, they live longer, but they‟re hungry,” he says, “Even seeing what a diet does , it‟s still hard to go to a restaurant and say: „I can only cat half of that‟.”

Spindler hopes we soon won‟t need to diet at all.His company, Lifespan Genetics in California, is looking for drugs that have the effects of caloric restriction.31.According to the passage, which of the following is NOT true?

A.Eating less than usual might make us live longer.B.we go on A diet when old, we may keep healthy.C.Dieting might not be needed.D.We have to begin dieting since childhood.32.Why does the author mention an elderly mouse in paragraph 2?

A.To describe the influence or old age on mice.B.To illustrate the effect of meager food on mice.C.To tell us how mice‟s liver genes behave.D.To inform us of the process of metabolizing drugs.33.What can he inferred about completely normally fed mice mentioned in the passage?

A.They will not experience free radical production.B.They will experience more genetic rejuvenation in their lifetime.C.They have more old liver genes to behave like young genes.D.They are more likely to suffer from inflammation.34.According to the author, which of the following most interested the researchers?

A.The mice that started dieting in old age.B.27 of those 46 old genes that continued to behave like young genes.C.Calorie restriction that works in people.D.Dieting that makes sure a drug is effective.35.According 10 the last two paragraphs, Spindler believes that

A.calorie restriction is very important to young people.B.seeing the effect of a diet, people will like to eat less than normal.C.dieting is not a good method to give us health and long life.D.drugs do not have the effects of calorie restriction.第二篇

Snowflakes

You‟ve probably heard that no two snowflakes are alike.Of course, nobody has ever confirmed that statement by examining every one of the estimated one septillion snowflakes that drift to Earth each year.Still, Kenneth Libbrecht, a professor at the California Institute of Technology, is confident that the statement is true.Snowflakes aren‟t flaky, says Libbrecht.At their basic level, they‟re crystalline.The lattice of every snowflake is six-sided in shape.The simplest snow crystals are six-sided flat plates and six-sided columns.Such crystals are common in places where the air is extremely cold and dry.Snow crystals acquire their special beauty when their simple six-sided symmetry blossoms.Under the right conditions, each of the six corners of a crystal sprouts1 what is called an arm.In a matter of minutes, the arms can become highly ornate and give the crystal a star like appearance.Several factors in the environment affect the shape and growth rate of a snow crystal.One factor is humidity.Crystals grow faster and in more intricate shape as humidity increases.A second factor is air temperature.A snowflake is born when several molecules of water vapor in a cloud land on a speck of dust and freeze to form a simple crystal.As the young crystal bops around in the cloud, it passes through air pockets of varying temperatures.If the crystal passes through a pocket of air that is, say,-15 degrees Celsius, it will grow quickly and sprout six arms says Libbrecht.If the crystal is then tossed into a warmer pocket, one about-100C, the arms tips will stop growing quickly and form six-sided plates.If the crystal then drifts into an even warmer pocket of about-50C, its top and bottom will grow more quickly than its sides and become more column like in shape.In the course of its life span, a snow-crystal might flutter through many warmer and colder pockets, acquiring a complicated and unique growth history.Such a history will give rise to a snowflake that is unlike any other.Each arm on the snowflake will look exactly like every other one, but the crystal itself will be one of a kind.Using his cooling tanks, Libbrecht has learned how to create snow crystals of different shapes-plates, columns, needles, etc.Libbrecht has even refined his techniques so that he can make crystals that look highly similar to one another.Still, he lacks the control to manufacture identical twin snowflakes.A slight difference in humidity and temperature can upset the growth profile of a crystal.36.What does Professor Libbrecht believe to be true?

A.No two snowflakes are exactly the same in shape.B.Somebody has examined all the snowflakes that fall on Earth.C.The statement that no two snowflakes are alike is confirmed.D.None of the above.37.What do the simplest snow crystals look like?

A.They have six columns.B.They are flaky.C.They are cubic in shape.D.They are six-sided.38.What are the factors that affect the shape and growth rate of a snow crystal?

A.Humidity and temperature.B.Water and falling speed.C.Air and altitude.D.Both B and C.39.It can be felt from the description in the 2nd paragraph that the author

A.admires the beauty of the snowflakes.B.dislikes the changing growth history of the snowflakes.C.has a particular feeling for those flower-like crystals.D.likes to compare snowflakes to the stars in the sky.40.Libbrecht is not able to

A.create snow crystals of different shapes.B.make crystals that look similar to one another.C.create snowflakes that era exactly alike.D.refine his techniques.第三篇

Ford Abandons Electric Vehicles

The Ford motor company‟s abandonment of electric cars effectively signals the end of the road for the technology, analysts say.General Motors and Honda ceased production of battery-powered cars in 1999, to focus on fuel cell and hybrid electric gasoline engines, which are more attractive to the consumer.Ford has now announced it will do the same.Three years ago, the company introduced the Think City two-seater car and a golf cart called the THINK or Think Neighhor.It hoped to sell 5,000 cars each year and 10,000 carts.But a lack of demand means only about 1,000 of the cars have been produced, and less than 1,700 carts have been sold so far in 2002.“The bottom line is we don‟t believe that this is the future of environment transport for the mass market,” Tim Holmes of Ford Europe said on Friday.“We feel we have given electric our best shot.”

The Think City has a range of only about 53 miles and up to a six-hour battery recharge time.General Motors‟ EVI electric vehicle also had a limited range, of about 100 miles.The very expensive batteries also mean electric cars cost much more than petrol-powered alternatives.An electric Toyota RAV4 EV vehicle costs over $42,000 in the US, compared with just $17,000 for the petrol version.Toyota and Nissan are now the only major auto manufacturers to produce electric vehicles.“There is a feeling that battery electric has been given its chance.Ford now has to move on with its hybrid program, and that is what we will be judging them on,” Roger Higman, a senior transport campaigner at UK Friends of the Earth, told the Environment News Service.Hybrid cars introduced by Toyota and Honda in the past few years have sold well.Hybrid engines offer greater mileage than petrol-only engines, and the batteries recharge themselves.Ford says it thinks such vehicles will help it meet planned new guidelines on vehicle emissions in the US.However, it is not yet clear exactly what those guidelines will permit.In June, General Motors and Daimler Chrysler won a court injunction, delaying by two years Californian legislation requiring car-makers to offer 100,000 zero-emission and other low-emission vehicles in the state by 2003.Car manufacturers hope the legislation will be rewritten to allow for more low-emission, rather than zero-emission, vehicles.41.What have the Ford motor company, General Motor‟s and Honda done concerning electric cars? A.They have started to produce electric cars.B.They have done extensive research on electric cars.C.They have given up producing electric cars.D.They have produced thousands of electric cars.42.According to Tim Holmes of Ford Europe, battery-powered cars

A.will be the main transportation vehicles in the future.B.will not be the main transportation vehicles in the future.C.will be good to the environment in the future.D.will replace petrol-powered vehicles in the future.43.Which auto manufacturers are still producing electric vehicles?

A.Toyota and Nissan.B.General Motor‟s and Honda.C.Ford and Toyota.D.Honda and Toyata.44.According to the eighth paragraph, hybrid cars

A.offer fewer mileage than petrol driven cars.B.run faster than petrol driven cars.C.run more miles than petrol driven cars.D.offer more batteries than petrol driven cars.45.Which of the following is true about the hope of car manufacturers according to the last paragraph?

A.Low-emission cars should be banned.B.Only zero-emission cars are allowed to run on motorways.C.The legislation will encourage car makers to produce more electric cars.D.The legislation will allow more low-emission to be produced.参考答案：

Mobile Phones

Mobile phones should carry a label if they proved1 to be a dangerous source of radiation, according to Robert Bell, a scientist.And no more mobile phone transmitter towers should be built until the long-term health effects of the electromagnetic radiation they emit are scientifically evaluated, he said.“Nobody‟s going to drop dead overnight but we should be asking for more scientific information,” Robert Bell said at a conference on the health effects of low-level radiation.46

A report widely circulated among the public says that up to now scientists do not really know enough to guarantee there are no ill-effets on humans from electromagnetic radiation.According to Robert Bell, there are 3.3 million mobile phones in Australia alone and they are increasing by 2,000 a day.47

As well, there are 2, 000 transmitter towers around Austrnlia, many in high density residential areas.48 The electromagnetic radiation emitted from these towers may have already produced some harmful effects on the health of the residents nearby.Robert Bell suggests that until more research is completed the Government should ban construction of phone towers from within a 500 metre radius of school grounds, child care centres, hospitals, sports playing fields and residential areas with a high percentage of children.49 He adds that there is also evidence that if cancer sufferers are subjected to electromagnetic waves the growth rate of the disease accelerates.50 According to Robert Bell, it is reasonable for the major telephone companies to fund it.Besides, he also urges the Government to set up a wide-ranging inquiry into possible health effects.A.He says there is emerging evidence that children absorb low-level radiation at a rate more than three times that of adults.B.By the year 20004 it is estimated that Australia will have 8 million mobile phones: nearly one for every two people.C.“If mobile phones are found to be dangerous, they should carry a warning label until proper shields can be devised,” he said.D.Then who finances the research?

E.For example, Telstra, Optus and Vodaphone build their towers where it is geographically suitable to them and disregard the need of the community.F.The conclusion is that mobile phones brings more harm than benefit.参考答案：46-50 CBEAD

Chicken Soup for the Soul：Comfort Food Fights Loneliness

Mashed potatoes, macaroni and cheese, may be bad for your arteries.51 according to a study in Psychological Science, they‟re good for your heart and 52.The study focuses on “comfort food” and how it makes people feel.“For me 53 , food has always played a big role in my family,” says Jordan Troisi, a graduate student at the University of Buffalo, and lead author on the study.The study came out of the research program of his co—author Shira Gabriel.It has 54 non-human things that may affect human emotions.Some people reduce loneliness by bonding with their 55 TV show, building virtual relationships with a pop song singer or looking at pictures of loved ones.Troisi and Gabriel wondered if comfort food could have the same effect 56 making people think of their nearest and dearest.In one experiment, in order to make 57 feel lonely, the researchers had them write for six minutes about a fight with someone close to them.Others were given an emotionally neutral writing assignment.Then, some people in each 58 wrote about the experience of eating a comfort food and others wrote about eating a new food.59 , the researchers had participants 60 questions about their levels of loneliness.Writing about a fight with a close person made people feel lonely.But people who were generally 61 in their relationships would feel less lonely by writing about a comfort food.“We have found that comfort foods are consistently associated with those close to us.”says Troisi.“Thinking about or consuming these foods later then serves as a reminder of those close others.” In 62 essays on comfort food, many people wrote about the 63 of eating food with family and friends.In another experiment, 64 chicken soup in the lab made people think more about relationships, but only if they considered chicken soup to be a comfort food.This was a question they had been asked long before the experiment, along with many other questions, so they wouldn‟t remember it.“Throughout everyone‟s daily lives they experience stress, often associated with our 65 with others,” Troisi says.“Comfort food Can be an easy remedy for loneliness.”

for more than two thousand years.It began as a small village beside the River Wensum.At the time of the Norman invasion in 1066 it had grown to become one of the largest towns in England.With two cathedrals and a mosque(清真寺), Norwich has long been a popular centre for various religions.The first cathedral was built in 1095 and has recently celebrated its 900th anniversary, while Norwich itself had a year of celebration in 1994 to mark the 800th anniversary of the city receiving a Royal Charter.This allowed it to be called a city and to govern itself independently.Today, in comparison with places like London or Manchester, Norwich is quite small, with a population of around 150,000, but in the 16th century Norwich was the second largest city of England.It continued to grow for the next 300 years and got richer and richer, becoming famous for having as many churches as there are weeks in the year and as many pubs as their are days in the year.Nowadays, there are far fewer churches and pubs, but in 1964 the University of East Anglia was built in Norwich.With its fast-growing student population and its success as a modern commercial centre(Norwich is the biggest centre for insurance services outside London),the city now has a side choice of entertainment: theatres, cinemas, nightclubs, busy cafes, excellent restaurants, and a number of arts and leisure centres.There is also a football team, whose colours are green and yellow.The team is known as “The Canaries(金丝雀)”,though nobody can be sure why.Now the city's attractions include another important development, a modern shopping centre called “The Castle Mall”.The people of Norwich lived with a very large hold in the middle of their city for over two years, as builders dug up the main car park.Lorries moved nearly a million tons of earth so that the roof of the mall could become a city centre park, with attractive water pools and hundreds of trees, but the local people are really pleased that the old open market remains, right in the heart of the city and next to the new development.Both areas continue to do good business, proving that Norwich has managed to mix the best of the old and the new.16

behavior may be the main cause of a health problem, but it can also be the main solution.This is true for the teenager who smokes, the mother with the poorly nourished（营养）child, and the butcher（屠夫，卖肉的人）who gets a cut on his finger.By changing their behavior these individuals can solve and prevent many of their own problems.2 Health education does not replace other health services, but it is needed to promote the proper use of these services.One example of this is immunization（免疫）: scientists have made many vaccines（疫苗）to prevent diseases, but this achievement is of no value unless people go to receive the immunization.3 Health education encourages behavior that promotes health, prevents illness, cures disease, and contributes to recovery.The needs and interests of individuals, families, groups, organizations, and communities are at the heart of health education programs.Thus there are many opportunities for practicing health education.4 Health education is not the same thing as health information.Correct information is certainly a basic part of health education, but health education must also address the other factors that affect health behavior such as availability（可获性）of resources, effectiveness of community leadership, social support from family members, and levels of self-help skills.Health education therefore uses a variety of methods to help people understand their own situations and choose actions that will improve their health.Health education is incomplete unless it encourages involvement and choice by the people themselves.5 Also, in health education we do not blame people if they do not behave in a healthy way.Often unhealthy behavior is not the fault of the individual.In health education we must work with families, communities, and even regional and national authorities to make sure that resources and support are available to enable each individual to lead a healthy life.23 Paragraph 2_________.24Paragraph 3_________.25 Paragraph 4_________.26 Paragraph 5_________.A Addressing a Variety of Behavior-affecting Factors B Importance of Immunization C Relationship with Other Health Services D Creation of Necessary Conditions for Healthy Behavior E Encouraging Unhealthy Behavior F Encouragement of Behavior Good for Your Health 27 Promoting healthy behavior is the goal of _________.28 Immunization helps to _________.29 Health education cannot take the place of_________.30 Individuals should be provided with necessary conditions for _________.A many vaccines B prevent diseases C health education D

个选项。请仔细阅读短文并根据短文回答其后面的问题，从 4 个选项中选择 1 个最佳答案涂在答题卡相应的位置上。第一篇 Small But Wise On December 14,NASA1 blasted a small but mighty telescope into space.The telescope is called WISE and is about as wide around as a trashcan.Don't let its small size fool you:WISE has a powerful digital camera, and it will be taking pictures of some the wildest objects2 in the known universe,including asteroids,faint stars,blazing galaxies3 and giant clouds of dust where planets and stars are born.“I'm very excited because we're going to be seeing parts of the universe that we haven't seen before,”said Ned Wright, a scientist who directs the WISE project.Since arriving in space,the WISE telescope has been circling the Earth,held by gravity in a polar orbit4(this means it crosses close to the north and south poles with each lap5).Its camera is pointed outward,away from the Earth,and WISE will snap a picture of a different part of the sky every 11 minutes.After six months it will have taken pictures across the entire sky.The pictures taken by WISE won't be like everyday digital photographs,however.WISE stands for“Wide-field Infrared Survey Explorer.”As its name suggests,the WISE camera takes pictures of features that give off infrared radiation6.Radiation is energy that travels as a wave.Visible light, including the familiar spectrum of light7 that becomes visible in a rainbow,is an example of radiation.When an ordinary digital camera takes a picture of a tree,for example,it receives the waves of visible light that are reflected off the tree.When these waves enter the camera through the lens,they're processed by the camera,which then puts the image together.Waves of infrared radiation are longer than waves of visible light, so ordinary digital cameras don't see them,and neither do the eyes of human beings.Although invisible to the eye,longer infrared radiation can be detected as warmth by the skin.That's a key idea to why WISE will be able to see things other telescopes can't.Not everything in the universe shows up in visible light.Asteroids,for example,are giant rocks that float through space 一 but they absorb most of the light that reaches them.They don't reflect light,so they're difficult to see.But they do give off infrared radiation, so an infrared telescope like WISE will be able to produce images of them.During its mission WISE will take pictures of hundreds of thousands of asteroids.Brown dwarfs8 are another kind of deep-space object that will show up in WISE's pictures.These objects are“failed” stars 一 which means they are not massive enough to jump start9 the same kind of reactions that power stars such as the sun.Instead,brown dwarfs simply shrink and cool down.They're so dim that they're almost impossible to see with visible light, but in the infrared spectrum they glow.31.What is so special about WISE? A It is small in size but carries a large camera.B It is as small as a trashcan.C Its digital camera can help astronomers to see the unknown space.D Never before has a telescope carried a digital camera in space.32.Which is NOT the synonym for the word “snap” in the third paragraph? A make.B shoot.C take D photograph.33.The camera on WISE A is no different from an ordinary camera.B does not see infrared radiation while the ordinary camera does.C catches the infrared radiation while the ordinary camera does not.D reflects light that human eyes can see.34.Which of the following is NOT correct about“asteroids” according to paragraph 7? A Asteroids float through space giving off visible light.B Asteroids do not reflect light that reaches them.C It is difficult to take asteroids' pictures by ordinary cameras, D The WISE telescope can take pictures of asteroids 35.What is implied in the last paragraph? A Brown dwarfs give off visible light.B Brown dwarfs give off infrared radiation.C Brown dwarfs are power stars like the sun.D Brown dwarfs are impossible to see with the WISE telescope.参考答案： 31 C 32 A 33 C 34 A 35 B 第二篇 Ants Have Big Impact on Environment as “Ecosystem Engineers” Research by the University of Exeter1 has revealed that ants have a big impact on their local environment as a result of their activity as “ecosystem engineers” and predators.The study, published in the Journal of Animal Ecology, found that ants have two distinct effects on their local environment.Firstly, through moving of soil by nest building2 activity and by collecting food they affect the level of nutrients in the soil.This can indirectly impact the local populations of many animal groups, from decomposers to species much higher up the food chain.Secondly, they prey on a wide range of other animals, including larger prey which can be attacked by vast numbers of ant workers.Dirk Sanders, an author of the study from the university's Centre for Ecology and Conservation, said:“Ants are very effective predators which thrive in huge numbers.They're also very territorial3 and very aggressive, defending their resources and territory against other predators.All of this means they have a strong influence on their surrounding area.” “In this research, we studied for the first time how big this impact is and the subtleties of it.What we found is that despite being predators, their presence can also lead to an increase in density and diversity of other animal groups4.They genuinely play a key role in the local environment, having a big influence on the grassland food web,” Sanders said.The study, carried out in Germany, studied the impact of the presence of different combinations and densities of black garden ants and common red ants, both species which can be found across Europe, including in the UK.It found that a low density of ants in an area increased the diversity and density of other animals in the local area, particularly the density of herbivores and decomposers.At higher densities ants had no or the opposite effect, showing that predation is counteracting the positive influence.Dr Frank van Veen, another author on the study, said:“What we find is that the impact of ants on soil nutrient levels has a positive effect on animal groups at low levels, but as the number of ants increases, their predatory impacts have the bigger effect — thereby counteracting the positive influence via ecosystem engineering.” Ants are important components of ecosystems not only because they constitute a great part of the animal biomass5 but also because they act as ecosystem engineers.Ant biodiversity6 is incredibly high and these organisms are highly responsive to human impact, which obviously reduces its richness.However, it is not clear how such disturbance damages the maintenance of ant services to the ecosystem． Ants are important in below ground processes8 through the alteration of the physical and chemical environment and through their effects on plants, microorganisms, and other soil organisms.36.Why are ants compared to ecosystem engineers? A Because they build their own nests.B Because they collect food.C Because their activity affects the environment.D Because they are predators.37.As predators, ants A prey on small as well as large animals.B collect nutritious food from the soil C collect food as decomposers.D prey on species much higher up the food chain.38.Dir Sanders' study centered on how ants A can manage to thrive in huge numbers.B defend their resources and territory against other predators.C attack those invading animals for survival.D produce such a big impact on the environment.39.What does paragraph 6 tell us? A Ants bring about a negative influence to an area when their population is small.B Ants bring about a positive influence to an area when their population is small.C Ants' predation counteracts the positive influence they may have on an area.D At higher density, ants produce a positive influence on an area.40.What still remains unclear about ants, according to the last paragraph? A What roles do ants play in the ecosystem in which they live? B How do ants affect the animal diversity in a given ecosystem? C How do human activities affect ants' influence on a given ecosystem? D How do ants alter the physical and chemical environment? 参考答案：36 C 37 A 38 D 39 B 40 C 第三篇 U.S.Marks 175 Locomotive Years Built by the Mason machine Worlds in 1856, the 27,900-kilogram William Mason was an example of the archetypal 19th Century American locomotive, the oldest in operation in the United States.The locomotive was transferred last month from its open bay in B＆O's historic roundhouse to ready it for this summer's Fair of the Iron Horse, a celebration of 175 years of American railroading, in the city of Baltimore, Maryland.Tests will show whether the old gauges and boiler pressure points are up to federal standards to operate during the six-day festival.“This is sort of the world's fair of railroading,” said Courtney Wilson, executive director of the B＆O Railroad Museum.The festival will run from June 28 to July 3 and display what organizers say is the most impressive collection of locomotives in the Western Hemisphere.At the museum, an area will be set aside for model trains to keep toddlers interested.Children will learn about safety rules around train tracks.Adults will be able to track the development of railroad technology－from horse power to steam and diesel power to magnetic levitation, which can push trains at speeds upward of 390 kph.“We have locomotives coming from all over the country, and we believe even the Rocket is coming from England--the very first locomotive in the world－to participate in this fair,” Wilson said.The Rocket, the first successful steam locomotive in the world, won a competition in 1829 as the fastest locomotive—an event that helped spark worldwide railway interest.“it was probably the fastest machine on Earth in its time,” Wilson said.Rail companies in France, Canada, Germany and Spain have been invited to participate in this year's event.“This will probably be the last time in this century that these many locomotives will be assembled in one spot, and it'll be a once-in-a lifetime experience,” Wilson said.The B＆O Railroad was the host of a similar event in 1927 in nearby Hale Thorpe that attracted more than 1.25 million visitors over three weeks.The railroad held the event for its 100th anniversary.Museum officials hope the event gives people a better appreciation of trains.The museum's 22-sided roundhouse will be a focal point in the months leading up to the festival.Completed in 1884, the building rises 40.5 meters into a huge cupola and covers nearly a half hectare of ground.The roundhouse has been in continuous use since its construction.Inside is the most significant collection of railroad artifacts in the nation, including a replica built in 1926 of the Tom Thumb—the first American built locomotive(constructed in 1830)—and the St.Elizabeth—one of the last steam engines built in the United States(1950).The museum, which sits on about 16 hectares in west Baltimore, holds locomotives, freight and passenger cars and other rolling stock－including cars from the nation's first trains, which were pulled by horses.41 William Mason was the oldest locomotive in operation ________.A in the world B in America C in England D in the region of Baltimore 42 The oldest locomotive will be put to tests again to make sure ________.A its commercial operation is safe B it competes with the Rocket in good shape C its technical information to be presented to the Fair is accurate D it is up to the federal standards before operation 43 Which of the following statements is NOT a correct description of the Rocket? A It was the first successful steam locomotive in the world.B It is believed to be the fastest locomotive in its time.C It will be put on display in festival.D It sped up the development of railroading in America.44 How large is the museum's roundhouse? A One-tenth of the museum.B 16 hectares.C One-thirty-second of the museum.D Not mentioned.45 Which of the following best describes the collection of the artifacts in the museum? A Its collection is important and representative.B The collection is not rich enough.C The replica of the Tom Thumb is disappointing.D The St.Elizabeth, one of the last steam engines is not among the artifacts.参考答案：41 B 42 D 43 D 44 C 45 A 第五部分：补全短文(第 46～50 题，每题 2 分，共 10 分)阅读下面的短文，文章中有 5 处空白，文章后面有 6 组文字，请根据文章的内容选择 5 组文字，将其分别放回文章原有位置，以恢复文章原貌。请将答案涂在答题卡相应的位置上。How to Jump Queue Fury If you find yourself waiting in a long queue at an airport or bus terminus this holiday, will you try to analyze what it is about queuing that makes you angry? Or will you just get angry with the nearest official? Professor Richard Larson, an electrical engineer at the Massachusetts Institute of Technology, hates queuing but rather than tear his hair out, he decided to study the subject.46.He cites an experiment at Houston airport where passengers had to walk for one minute from the plane to the baggage reclaim and then wait a further seven minutes to collect their luggage.Complaints were frequent, especially from those who had spent seven minutes watching passengers with just hand baggage get out immediately.The airport authorities decided to lengthen the walk from the aircraft, so that instead of a one-minute fast walk, the passengers spent six minutes walking 47 The extra walk extended the delay by five minutes for those carrying only hand baggage, but passenger complaints dropped almost to zero.The reason? Larson suggests that it all has to do with what he calls “social justice”.If people see others taking a short cut, they will find the wait unbearable.48 Another aspect Larson studied was the observation that people get more fed up if they are not told what is going on.49 But even knowing how long we have to wait isn't the whole answer.We must also believe that everything is being done to minimize our delay.Larson cites the example of two neighboring American banks.One was highly computerized and served a customer, on average, every 30 seconds.50.But because the tellers at the second bank looked extremely busy, customers believed the service was faster and many transferred their accounts to the slower bank.Ultimately, the latter had to introduce time-wasting ways of appearing more dynamic.A So in the case of the airport, it was preferable to delay everyone.B The other bank was less automated and took twice as long.C When they finally arrived at the baggage reclaim, the delay was then only two minutes.D His first finding, which backs up earlier work at the US National Science Foundation, was that the degree of annoyance was not directly related to the time.E It's unbearable for the airport to delay everyone.F Passengers told that there will be a half-hour delay are less unhappy than those left waiting even twenty minutes without an explanation.第六部分：完型填空(第 51～65 题，每题 1 分，共 15 分)阅读下面的短文，文中有 15 处空白，每处空白给出了 4 个选项，请根据短文的内容从 4 个选项中选择 1 个最佳答案，涂在答题卡相应的位置上。“Liquefaction” Key to Much of Japanese Earthquake Damage The massive subduction zone1 earthquake in Japan caused a significant level of soil “liquefaction” that has surprised researchers with its 51severity, a new analysis shows.“We've seen localized3 examples of soil liquefaction as extreme as this before, but the distance and 52 of damage in Japan were unusually severe,” said Scott Ashford, a professor of geotechnical engineering4 at Oregon State University.“Entire structures were tilted and sinking into the sediments,” Ashford said.“The shifts in soil destroyed water, drain and gas pipelines6, crippling the utilities and infrastructure these communities need to 53.We saw some places that sank as much as four feet.” Some degree of soil liquefaction7 is common in almost any major earthquake.It's a phenomenon in which soils soaked with water, particularly recent sediments or sand, can lose much of their 54 and flow during an earthquake.This can allow structures to shift or sink or 55.But most earthquakes are much 56 than the recent event in Japan, Ashford said.The length of the Japanese earthquake, as much as five minutes, may force researchers to reconsider the extent of liquefaction damage possibly occurring in situations such as this8.“With such a long-lasting earthquake, we saw 57 structures that might have been okay after 30 seconds just continued to sink and tilt as the shaking continued for several more minutes,” he said.“And it was clear that younger sediments, and especially areas built on 58 filled ground, are much more vulnerable.” The data provided by analyzing the Japanese earthquake, researchers said, should make it possible to improve the understanding of this soil 59 and better prepare for it in the future.Ashford said it was critical for the team to collect the information quickly, 60 damage was removed in the recovery efforts9.“There's no doubt that we'll learn things from what happened in Japan10 that11 will help us to reduce risks in other similar 61 ,” Ashford said.“Future construction in some places may make more use of techniques known to reduce liquefaction, such as better compaction to make soils dense, or use of reinforcing stone columns.” Ashford pointed out that northern California have younger soils vulnerable to liquefaction---on the coast, near river deposits or in areas with filled ground.The “young” sediments, in geologic terms, may be those 62 within the past 10,000 years or more.In Oregon, for instance, that describes much of downtown Portland, the Portland International Airport and other cities.Anything 63 a river and old flood plains is a suspect12, and the Oregon Department of Transportation has already concluded that 1,100 bridges in the state are at risk from an earthquake.Fewer than 15 percent of them have been reinforced to 64 collapse.Japan has suffered tremendous losses in the March 11 earthquake, but Japanese construction 65 helped prevent many buildings from collapse---even as they tilted and sank into the ground.下载本文档需要登录，并付出相应积分。如何获取积分?

Some People Do Not Taste Salt Like Others(A级)(无换题现象)

Low-salt foods may be harder for some people to like than others, according to a study by a Penn State College of Agricultural Sciences1 food scientist.The research indicates that genetic factors influence some of the difference in the levels of salt we like to eat.Those conclusions are important because recent, well-publicized efforts to reduce the salt content in food2 have left many people struggling to accept fare that simply does not taste as good to them as it does to others3, pointed out John Hayes, assistant professor of food science, who was lead investigator? on the study.Diets high in salt can increase the risk of high blood pressure and stroke.That is why public health experts and food companies are Working together on ways to help consumers lower salt intake through foods that are enjoyable to eat.This study increases understanding of salt preference and consumption.The research involved 87 carefully screened participants who sampled salty foods such as soup and chips, on multiple occasions, spread out over weeks5.Test subjects were 45 men and 42 women, reportedly healthy, ranging in age from 20 to 40 years.The sample was composed of individuals who were not actively modifying their dietary intake and did not smoke cigarettes.They rated the intensity of taste on a commonly used scientific scale, ranging from barely detectable to strongest sensation of any kind.“Most of us like the taste of salt.However, some individuals eat more salt, both because they like the taste of saltiness more, and also because it is needed to block other unpleasant tastes in food,” said Hayes.“Supertasters, people who experience tastes more mtensely, consume more salt than nontasters do.Snack foods have saltiness as their primary flavor, and at least for these foods, more is better, so the supertasters seem to like them more.”

However, supertasters also need higher levels of salt to block unpleasant bitter tastes in foods such as cheese, Hayes noted.“For example, cheese is a wonderful blend of dairy flavors from fermented, milk, but also bitter tastes from ripening that are blocked by salt,” he said.“A supertaster finds low-salt cheese unpleasant because the bitterness is too pronounced6.Hayes cited research done more than 75 years ago by a chemist named Fox and a geneticist named Blakeslee, showing that individuals differ in their ability to taste certain chemicals.As a result, Hayes explained, we know that a wide range in taste acuity exists, and this variation is as normal as variations in eye and hair color.”Some people, called supertasters, describe bitter compounds as being extremely bitter, while others, called nontasters, find these same bitter compounds to be tasteless or only weary bitter,“ he said.”Response to bitter compounds is one of many ways to identify biological differences in food preference because supertasting7 is not limited to bitterness.(476)

第一篇

Ocean Noise Pollution

Some scientists say that animals in the ocean are increasingly threatened by noise pollution caused by human beings.The noise that affects sea creatures comes from a number of human activities.It is caused mainly by industrial underwater explosions, ocean drilling, and ship engines.Such noises are added to natural sounds.These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves.Decibels(分贝)measured in water are different from those measured on land.A noise of one hundred-twenty decibels on land causes pain to human ears.In water, a decibel level of one-hundred ninety-five would have the same effect.Some scientists have proposed setting a noise limit of one-hundred-twenty decibels in.oceans.They have observed that noises at that level can frighten and confuse whales(鲸鱼).A team of American and Canadian scientists discovered that louder noises can seriously injure some animals.The research team found that powerful underwater explosions were causing whales in the area to lose their hearing.This seriously affected the whales' ability to exchange information and find their way.Some of the whales even died.The explosions had caused their ears to bleed(出血)and become infected(感染).Many researchers whose work depends on ocean sounds object to a limit of one-hundred-twenty decibels.They say such a limit is a greater danger than they believed.They want to prevent noises from harming creatures in the ocean.31 According to the passage, which of the following is increasingly dangerous to sea creatures?

A The sound of a car.B The sound of voices.C Man-made noise pollution.D The sound of steps.32 According to the passage, natural sounds include all of the following EXCEPT__________.A sounds made by animals themselves.B ocean drilling.C underwater earthquakes.D the breaking of ice fields.，33 Which of the following is discussed in the third paragraph?

A The same noise level produces a different effect on land and in the ocean.B Different places may have different types of noises.C The decibel is not a suitable unit for measuring underwater noise.D Different ocean animals may have different reactions to noises.34 Which of the following is true of whales?

A They won't be confused by noises.B They are deaf to noises.C Their ability to reproduce will be lowered by high-level noises.D Their hearing will be damaged by high-level noises.35 According to the passage, what will scientists most probably do in the future?

A They will work hard to reduce ocean noise pollution.B They will protect animals from harmful noises.C They will try to set a limit of 120 decibels.D They will study the effect of ocean noise pollution.第二篇

Lifetime Employment in Japanese Companies

In most large Japanese companies, there is a policy of lifetime employment.What this means is that when people leave school or university to join an enterprise, they can expect to remain with that organization until they retire.In effect, the employee gets job security for life, and can only be fired for serious mistakes in work.Even in times of business recession, he or she is free from the fear of being laid off.One result of this practice is that the Japanese worker identifies closely with his company and feels strong loyalty to it.By working hard for the company, he believes he is safeguarding his own future.It is not surprising that devotion to one's company is considered a great virtue in Japan.A man is often prepared to put his firm's interests before those of his immediate family.The job security guaranteed by this system influences the way employees approach their work.They tend to think in terms of what they can achieve throughout their career.This is because they are not judged on how they are performing during a short period of time.They can afford to, take a longer perspective than their Western counterparts.This marriage between the employee and the companymay explain why Japanese workers seem positively to love the products their company is producing and why they are willing to stay on after work, for little overtime pay, to participate in earnest discussions about the quality control of their products.36 Lifetime employment in the Japanese company means that the employee__________.A leaves his company only when business is bad.B gets a job soon after he leaves school or university.C can work there throughout his career，D can have his serious mistakes in work corrected.37 Which of the following statements is INCORRECT?

A Family and company interests are equally important

B The Japanese worker is very loyal to his company.C One's future is guaranteed through hard work.D Devotion to one's company is encouraged……

Lifetime employment influences one's__________.A achievements at work.B performance at work.C career options.D attitude toward work.39 The Japanese worker is fond of his company's products because of__________.A his marriage with the daughter of the president.B the close link between him and his company.C his willingness to work overtime.D his active participation in quality control，40 The passage mainly discusses__________.A how lifetime employment works in Japan.B what benefits lifetime employment has brought to Japanese workers.C what lifetime employment is.D how lifetime employment is viewed.第三篇

Dreams of Flight

The story of man's dream of flight, of his desire to reach the stars, is as old as mankind itself.According to Greek legend, Daedalus was the first man to fly.He and his son had been kept on an island.In order to escape, Daedalus shaped wings of wax(2)into which he stuck bird feathers.During their flight, his son flew too high and the sun melted the wax.He was drowned in the sea.The father was supposed to have continued his flight and reached Sicily, several hundred miles away.There is also an English legend of King Bladud who, during his rule in the ninth century B.C., used wings to fly.But his flight was short-lived and he fell to his death.The dream of flying continued, but in all the legends, the flier rose like a bird only to fall like a stone.It took hundreds of years that men flew up into the air and returned to earth safely.The first man to approach flying on a scientific basis was an Englishman who lived during the thirteenth century.He looked at the air about us as a sea, and he believed that a balloon could float on the air just as a boat did on water.Almost four hundred years later, an Italian priest applied his principle of air flight.He designed a boat, which would be held in the air by four hollow spheres(空心球).ach of the four balls was to be 20 feet in diameter(直径)and made of very thin copper.But his boat was never built since it was not possible to make spheres of such thin metal and such size in those days.After studying the flight of birds and the movement of the air, a great scientist of the fifteenth century concluded that birds flew because they flapped(摆动)their wings and that it was possible for man to do the same.So a kind of flapping-wing flying machine was invented.Many men tried and failed to fly with flying machines.It was not until 1890 that people discovered why this method would never succeed-man could not develop sufficient power with his arms and legs.41 How did Daedalus manage to escape to Sicily, according to the passage?

A He killed the guards and got out of the island.B A god came to rescue him and took him away.C His son came to rescue him and took him away.D He made wings of wax and flew away from the island.42 According to the English legend, King Bladud lost his life because__________.A he flew too far.B he flew too high.C he fell to the ground，D he was hit by a stone.43 The first scientific air flight was designed by__________.A a Greek.B an Englishman.C a Chinese.D an Italian.44 The priest failed to build the boat because__________.A he could not raise enough money.B his design was not scientific.C he could not find enough copper.D copper spheres could not be made as designed

According to the last paragraph, man could not fly with flapping-wing flying machines because__________.A he could not develop adequate power with his arms and legs.B he knew nothing about the movement of the air.C they were made of heavy metal.D they were made of light feathers.第5部分：补全短文(第46～50题，每题2分，共10分)

The Building of the Pyramids

The oldest stone buildings in the world are the pyramids.__________(46)There are over eighty of them scattered along the banks of the Nile, some of which are different in shape from the true pyramids.The most famous of these are the “Step” pyramid and the “Bent” pyramid.Some of the pyramids still look much the same as they must have done when they were built thousands of years ago.Most of the damage suffered by the others has been at the hands of men who were looking for treasure or, more often, for stone to use in modern buildings.__________(47).These are good reasons why they can still be seen today, but perhaps the most important is that they were planned to last for ever.__________(48).However, there are no writings or pictures to show us how the Egyptians planned or built the pyramids themselves.__________(49)

Nevertheless, by examining the actual pyramids and various tools Which have been found, archaeologists have formed a fairly clear picture of them.One thing is certain: there must have been months of careful planning before they could begin to build.__________(50)You may think this would have been easy with miles and miles of empty desert around, but a pyramid could not be built just anywhere.Certain rules had to be followed, and certain problems had to be overcome.A The dry climate of Egypt has helped to preserve the pyramids, and their very shape have made them less likely to fall into ruin.B It is practically certain that plans were made for the building of the pyramids because the plans of other large works have fortunately been preserved.C The first thing they had to do was to choose a suitable place.D Consequently, we are only able to guess at the methods used.E Many people were killed while building the pyramids.F They have stood for nearly 5,000 years, and it seems likely that they will continue to stand for thousands of years yet.第6部分：完形填空(第51～65题，每题1分，共15分)

Transportation

For many years in the desert, camels Used to be the only form of transportation(运输).Before the(51)of modern trains, camel trains used to carry all the goods for trading between Central Africa and Europe.Traders sometimes(52)to put together camel trains with 10,000 to 15,000 animals.Each animal often carried(53)400 pounds and could travel twenty miles a day.This form of transportation was so important that camels were called the “ships of the(54).”

Now modern trains travel across the desert in a very(55)time.One engine can pull as much weight as 135,000(56).In addition, trains use special cars for their load.Refrigerator cars carry food;boxcars carry heavy goods;stock cars carry animals;and tank cars carry oil.Air travel has changed, too.The earliest planes were biplanes(双翼飞机), with(57)sets of wings.The top speed of this plane was 60 miles per hour.The pilots used to sit or lie on the wings in the open air.The plane(58)sometimes stopped in the middle of a trip.It used to be(59)to fly in bad weather.In snow or in rain, the wings frequently became icy.Then the plane might go down.Mechanical improvements during the First World War changed airplanes.Monoplanes(单翼飞机)took the(60)of biplanes.Pilots flew inside of covered cabins.Still, even these planes were small and expensive.Only(61)people were be able to travel in airplanes.Now modern jets make air travel possible for all people.No place in the world is more than 24 hours away by jet.Further improvements have(62)the cost of flying, and they have made air travel(63)safer than it used to be.A modern 707 can carry 170 people and can fly at 600 miles per hour.People(64)used to eat, sleep, or watch movies on airplanes.(65)these things are a normal part of air travel!

Winners and Losers

Why are the biggest winners in the past decade of trade globalization mostly in South and East Asia, whereas the biggest losers are mostly in the former Soviet bloc(集团)and sub-Saharan Africa? History is a partial guide: East Asia has a long trading tradition, lately reinvigorated(给以新的活力)by the Chinese adoption of market economics.The Soviet Union, on the other hand, was sheltered from free-market forces for more than 70 years.In Africa, some countries are disadvantaged because of inadequate infrastructure(基础结构);many countries have little to trade but commodities, the prices of which have fallen in recent years.In some regions, certain countries have suffered by adopting misguided policies;often under pressure from International Monetary Fund.First among these is Russia, which in the early 1990s tried to embrace capitalism before first building the institutions that make capitalism work, such as an independent bank system, a system of business law, and an adequate method for collecting taxes.Encouraged by the IMF, the World Bank and the U.S.Department of the Treasury, President Boris Yeltsin's regime privatized the state-owned industrial sector, creating a class of oligarchs(寡头政治集团成员), who, knowing how unstable conditions were at home, sent their money abroad instead of investing it at home.In contrast, China, the biggest winner from globalization, did not follow the IMF formula.Of the former states of the Soviet bloc, only a few, notably Poland and Hungary, managed to grow, which they did by ignoring IMF advice and adopting expansionary plans, including spending more than they collected in taxes.Botswana and Uganda are also success stories: despite their disadvantages, their countries achieved vigorous growth by creating stable civil societies, liberalizing trade and implementing reforms that ran counter to IMF prescriptions.Japan has a long trading tradition.A Right

English and English Community There is no denying that English is a useful language.The people who speak English today make up the largest speech community in the world with the exception of speakers of Chinese.Originally they were small tribes of people from northern Europe who settled in England.Their languages became more and more similar to each other.Finally, the language had enough uniformity to be used by all speakers in England.The people were united into a speech community through their shared language.A speech community is similar to other kinds of communities.The people who make up the community share common language.Often they live side by side, as they do in a neighborhood, a village, or a city.More often they form a whole country.National boundaries, however, are not always the same as the boundaries of a speech community.A speech community is any group of people who speak the same language no matter where they happen to live.We may say that anyone who speaks English belongs to the English speech community.For convenience, we may classify the speakers into two groups: one in which the speakers use English as their native language, the other in which the speakers learn English as a second language for the purpose of education, commerce, and so on.English serves as an alternative language in several areas of public activity for the many nations of the world which employ it as an international second language.English has been adopted as the language of air traffic, commerce, as well as international diplomacy.Moreover, English is the language of the majority of published materials in the world so that education has come to rely heavily on an understanding of English.Learning second language extends one's vision and expands the mind.The history and literature of a second language record the real and fictional lives of people and their culturel;a knowledge of them adds to our ability to understand and to feel as they feel.Learning English as a second language provides another means of communication through which the window of the entire English speech community becomes a part of our heritage.Paragraph 2 ___________ Paragraph 3 ___________ Paragraph 4 ___________ Paragraph 5 ___________ A The Wide Use of English

B Historical Account of English and Its Community

C The Advantages of Learning a Second Language

D The Composition of the English Community

E The Threat That English Poses to Other Languages

F The Definition of a Speech Community Only through the shared language ___________.The idea of the national boundaries in often different from ___________.Speakers are classified into two groups ___________.An understanding of English ___________.A that of a speech community

B can a speech community be formed

C in order to learn English better

D for the sake of simplicity

E has played an important role in the field of education

F is widely used in several areas of public activity

第一篇 Hair Detectives

Scientists have found a way to use hair to figure out where a person is from and where that person has been.The finding could help solve crimes, among other useful applications.Water is central to the new technique.Our bodies break water down into its parts: hydrogen and oxygen.Atoms of these two elements end up in our tissues and hair.But not all water is the same.Hydrogen and oxygen atoms can vary in how much they weigh.Different forms of a single element are called isotopes.And depending on where you live, tap water contains unique proportions of the heavier and lighter isotopes of hydrogen and oxygen.Might hair record these watery quirks? That's what James R.Ehleringer, an environmental scientist at the University of Utah in Salt Lake City, wondered.To find out, he and his colleagues collected hair from barbers and hair stylists in 65 cities in 18 states across the United States.The researchers assumed that the hair they collected came from people who lived in the area.Even though people drink a lot of bottled water these days, the scientists found that hair overwhelmingly reflected the concentrations of hydrogen and oxygen isotopes in local tap water.That's probably because people usually cook their food in the local water.What's more, most of the other liquids people drink including milk and soft drinks contain large amounts of water that also come from sources within their region.Scientists already knew how the composition of water varies throughout the country.Ehleringer and colleagues combined that information with their results to predict the composition of hair in people from different regions.One hair sample used in Ehleringer's study came from a man who had recently moved from Beijing, China, to Salt Lake City.As his hair grew, it reflected his change in location.The new technique can't point to exactly where a person is from, because similar types of water appear in different regions that span a broad area.But authorities can now use the information to analyze hair samples from criminals or crime victims and narrow their search for clues.31 What does the writer say about tap water? Which of the following is NOT correct? ___________

A Tap water reflects the concentrations of hydrogen and oxygen isotopes in different regions.B Tap water is a kind of soft drink in the United States.C Tap water contains unique proportions of isotopes of hydrogen and oxygen.D Tap water is used to cook food.32 James R.Ehleringer tried to find out___________.A if our bodies break water down into its parts

B if it is possible to collect hair samples across the country

C if tap water contains unique proportions of isotopes of hydrogen and oxygen

D if the composition of hair can indicate exactly where people are from

Which of the following statements is meant by the writer? ___________

A Ehleringer was successful in his research.B Ehleringer failed in his research.C Ehleringer can be a successful detective.D Ehleringer's research proved successful in China.34 What does the last paragraph tell you? ___________

A The new technique can tell precisely where a person lives.B Water supplied in different regions all come from the same source.C Types of water used in different regions provide useful information for the police.D Hair samples provide the most important clues to identify crimes.35 Which of the following is closest in meaning to the title? ___________

A Human hair may help detectives to solve crimes.B Animal hair may help detectives to solve crimes.C Detectives watch hairy criminals closely.D Most detectives are hair specialists.第二篇 Why They Travel?

Scholars and students have always been great travellers.The official case for“academic mobility” is now often stated in impressive terms as a fundamental necessity for economic and social progress in the world, and debated in the corridors of Europe, but it is certainly nothing new.Serious students were always ready to go abroad in search of the most stimulating teachers and the most famous academies;in search of the purest philosophy, the most effective medicine, the likeliest road to gold.Mobility of this kind meant also mobility of ideas, their transference across frontiers, their simultaneous impact upon many groups of people.The point of learning is to share it, whether with students or with colleagues;one presumes that only eccentrics have no interest in being credited with a startling discovery, or a new technique.It must also have been reassuring to know that other people in other parts of the world were about to make the same discovery or were thinking along the same lines, and that one was not quite alone, confronted by inquisition, ridicule or neglect.In the twentieth century, and particularly in the last 20 years, the old footpaths of the wandering scholars have become vast highways.The vehicle which has made this possible has of course been the aeroplane, making contact between scholars even in the most distant places immediately feasible, and providing for the very rapid transmission of knowledge.Apart from the vehicle itself, it is fairly easy to identify the main factors which have brought about the recent explosion in academic movement.Some of these are purely quantitative and require no further mention: there are far more centres of learning, and a far greater number of scholars and students.In addition one must recognise the very considerable multiplication of disciplines, particularly in the sciences, which by widening the total area of advanced studies has produced an enormous number of specialists whose particular interests are precisely defined.These people would work in some isolation if they were not able to keep in touch with similar isolated groups in other countries.Frequently these specialisations lie in areas where very rapid developments are taking place, and also where the research needed for developments is extremely costly and takes a long time.It is precisely in these areas that the advantages of collaboration and sharing of expertise appear most evident.Associated with this is the growth of specialist periodicals, which enable scholars to become aware of what is happening in different centres of research and to meet each other in conferences and symposia.From these meetings come the personal relationships which are at the bottom of almost all formalized schemes of cooperation, and provide them with their most satisfactory stimulus.But as the specialisations have increased in number and narrowed in range, there had been an Opposite movement towards interdisciplinary studies.These owe much to the belief that one cannot properly investigate the incredibly complex problems thrown up by the modern world, and by recent advances in our knowledge along the narrow front of a single discipline.This trend has led to a great deal of academic contact between disciplines, and a far greater emphasis on the pooling of specialist knowledge, reflected in the broad subjects chosen in many international conferences.36 According to the passage, scholars and students are great travellers because __________.A standards are higher at foreign universities

B their governments encourage them to travel

C salaries and conditions are better abroad

D they are eager for new knowledge

The writer says that travel was important in the past because it __________.A was a way of spreading ideas

B broke down political barriers

C led to economic progress

D made new ideas less schooling

The writer claims that it is important for specialists to be able to travel because _________.A there are so many people working in similar fields

B there is a lot of social unrest at universities

C their follow experts are scattered round the world

D their laboratories are in remote places

The writer thinks that the growth of specialist societies and periodicals has helped scholars to __________.A spend less time travelling

B cut down research costs

C develop their ideas more quickly

D keep up with current developments

Developments in international cooperation are often, it is suggested, the result of __________.A friendships formed by scholars at meetings

B articles in learned journals

C the work of international agencies

D programs initiated by governments

Geography and Movement

To understand how astrology works, we should first take a quick look at the sky.Although the stars are at enormous distances, they do indeed give the impression of being affixed to the inner surface of a great hollow sphere surrounding the earth.Ancient people, in fact, literally believed in the existence of such a celestial sphere.As the earth spins on its axis, the celestial sphere appears to turn about us each day, pivoting at points on a line with the earth's axis of rotation.This daily turning of the sphere carries the stars around the sky, causing most of them to rise and set, but they, and constellations they define, maintains fixed patterns on the sphere, just as the continent of Australian maintains its shape on a spinning globe of the earth.Thus the stars were called fixed stars.The motion of the sun along the ecliptic is, of course, merely a reflection of the revolution of the earth around the sun, but the ancients believed the earth was fixed and the sun had and independent motion of its own, eastward among the stars.The glare of sunlight hides the stars in daytime, but the ancients were aware that the stars were up there even at night, and the slow eastward motion of the sun around the sky, at the rate of about thirty degrees each month, caused different stars to be visible at night at different times of the year.The moon, revolving around the earth each month, also has an independent motion in the sky.The moon, however, changes it position relatively rapidly.Although it appears to rise and set each day, as does nearly everything else in the sky, we can see the moon changing position during as short an interval as an hour or so.The moon's path around the earth lies nearly in the same plane as the earth's path around the sun, so the moon is never seen very far from the ecliptic in the sky.There are five other objects visible to the naked eye that also appear to move in respect to the fixed background of stars on the celestial sphere.These are the planets Mercury, Venus, Mars, Jupiter, and the Saturn.All of them revolve around the sun in nearly the same plane as the earth does, so they, like the moon, always appear near the ecliptic.Because we see the planets from the moving earth, however, they behave in a complicated way, with their apparent motions on the celestial sphere reflecting both their own independent motions around the sun and our motion as well.41 The ancient people believed that ___________.A the earth was spinning on the axis of the sky

B the sky was a hollow sphere spinning around the earth

C the patterns of stars on the sky would never change

D the stars around the sky were not stationary

Which of the following is true about the motion of the moon? ___________

A The moon and the sun are moving in the same plane.B The moon revolved along the ecliptic.C The moon moves faster than the sun.D The position of the moon can be found changed in an hour's time.43 It is stated in astrology that ___________.A the sun is so distant from us that it was hard to follow its motion

B the sun was moving westward around the sky

C the motion of the sun is at the rate of about thirty degrees every week

D the motion of the sun is similar to the revolution of the earth around the sun

All the other five planets ___________.A always appear near the path of the sun

B are moving in a way more complicated than the earth does

C aren't moving around the sun as independently as the earth does

D are moving around the sun at the same speed as the earth does

According to the passage which of the following is true? ___________

The development of agriculture and the balance between food and population are China's fun-damental economic problems.The classical histories praise emperors for devotion to agriculture and much of China's modern history is 46, which has been growing steadily.Today, although agriculture accounts for only a quarter of the Gross National Product, it is still the main determinant of the standard of living and the principal occupation of at least 70 percent of the population.Agriculture also 47 because industry needs both agricultural raw materials and food for its work force.The failure of agriculture to supply raw materials and food halted and later reversed the industrial progress of the 1950's.After 1960 new emphasis was placed on agriculture, and the slogan “griculture is the foundation of the economy” has remained a central Chinese economic policy ever since.48, there is an indirect link due to the relationship between agriculture and foreign trade.Many of China's exports are 49 or consumer goods based on them.Flourishing agriculture, therefore, promotes exports.It also reduces the need to spend foreign exchange on imports of grain and cotton, therefore 50

Avalanche and Its Safety

An avalanche is a sudden and rapid flow of snow, often mixed with air and water, down a mountainside.Avalanches are 51 the biggest dangers in the mountains for both life and property.All avalanches are caused by an over-burden of material, typically snowpack, that is too massive and unstable for the slope 52 supports it.Determining the critical load, the amount of over-burden which is 53 to cause an avalanche, 54 a complex task involving the evaluation of a number of factors.Terrain slopes flatter than 25 degrees or steeper than 60 degrees typically have a low 55 of avalanche.Snow does not 56 significantly on steep slopes;also, snow does not 57 easily on flat slopes.Human-triggered avalanches have the greatest incidence when the snow's angle of rest is 58 35 and 45 degrees;the critical angle, the angle at which the human incidence of avalanches is greatest, is 38 degrees.The rule of thumb is: A slope that is 59 enough to hold snow but steep enough to ski has the potential to generate an avalanche, regardless of the angle.Additionally, avalanche risk increases with 60;that is, the more a slope is disturbed by skiers, the more likely it is that an avalanche will occur.Due to the complexity of the subject, winter travelling in the backcountry is never 100% safe.Good avalanche safety is a continuous 61，including route selection and examination of the snowpack, weather 62，and human factors.Several well-known good habits can also 63 the risk.If local authorities issue avalanche risk reports, they should be considered and all warnings should be paid 64 to.Never follow in the tracks of others without your own evaluations;snow conditions are almost certain to have changed since they were made.Observe the terrain and note obvious avalanche paths where plants are 65 or damaged.Avoid traveling below others who might trigger an avalanche.51 A among

第二部分： A这道题的依据是第一段中的一句话：East Asia has a long trading tradition.日本是东亚国家，因而具有悠久的贸易历史。A本题的依据可以在第二段的开头找到，文章说有些国家常常是在有压力的情况下采取了国际货币基金组织(IMF)误导的政策，俄罗斯就是这些国家中的一个。B在文章的最后一段提到了一些因为没有按照IMF的模式去发展而获得成功的例子，其中提到两个非洲国家Botswans和Uganda，因而说所有非洲国家都采纳IMF模式的说法是不对的。B第一段里有一句话：The Soviet Union，on the other hand，was sheltered from free-market forces for more than 70 years.70多年不搞市场经济的国家自然不会是资本主义国家。C文中没有提到澳大利亚。A本题的依据是文章最后一段的第一句话：„，China，the biggest winner from globalization，did not follow the IMF formula.即中国没有按照IMF的建议去做。

C在第二段的末尾讲到前苏联搞私有化的事，但没有说有高官在私有化过程中受益。

第三部分： F此段解释何为语言群体，最后一句话是关键，可以看作是语言群体的定义。

D此段是讲英语语言群体包括的两类人，所以用composition“构成”一词。

A此段讲述英语在全世界许多领域被广泛应用，如航空、商务、外交、教育等。C此段主要谈的是学习第二语言的益处，最后一句话更具体到学习英语的益处。

B答案来自第一段最后一句，说明人们是通过他们所拥有的共同语言组成一个语言群体。以only开头的句子谓语部分要求使用倒装句。A第二段第四句话表明国界与语言群体的界限并不总是一致的。that用来替代the+有关前述名词，以避免重复。D第三段第二句表明为了方便起见我们将说话者分为两类。for the sake of指“出于„„的考虑”。E第四段最后一句话表明教育越来越依赖对英语的理解。也就是说对英语的理解能力在教育中起着重要的作用。第四部分：

B第三段和第六段谈到tap water。A、C、D均是文中提到的内容。B是错误的，因为文章第六段说，我们饮用的牛奶和饮料都含有大量水分，而没有说tap water是软饮料。

C第四段的问句针对第三段的内容。these watery quirks指的是上段中的unique pro-portions of the heavier and lighter isotopes of hydrogen and oxygen。所以C是正确答案。

A第六段和第七段提供了答案。科学家发现头发能反映出当地自来水中氢、氧同位素的含量;科学家也已经研究出不同地区水成分是不同的，并且在此基础上来确定来自不同地区的人的头发成分。

C选项A、B、D与原文均有出入。尽管在一个较大的范围内，人们使用成分较为相同的水，但是水的成分组成提供的信息可以帮助官方缩小破案线索范围。

A题目的意思是：人的头发可以帮助侦探破案。

D根据文章第一段的最后一句话可以判断学生们出国是因为寻找更能让人受到鼓舞的老师，更有名的学府，更纯粹的哲学等。由此可见选项D最符合题意。

A根据文中第三段的最后一句话“„and providing for the very rapid transmission of knowledge”可以看得出为了更快地传播知识是他们旅游的主要目的。所以A应为正确答案。

A本题所涉及的相关信息在文章第五段。根据题意可以得知学科的繁殖导致了大量科学家的诞生，他们如果不相互交流就不得不孤立地工作。由此可判断A为最佳选择。

C根据文中最后一句话“This trend has led to a great deal of academic contac between disciplines，and a far greater emphasis on the pooling of special knowledge，„”可以推断C为最佳答案。

A文章倒数第二段最后一句话说“From these meetings come the personal relationships which are at the bottom of almost all formalized schemes of cooperation，and provide with their most satisfactory stimulus”，这里的“personal relationships”指的就是“friendship”。由此可见A应为正确答案。

C根据第一段最后两句话，我们可以看出古人认为是地球的转动带动了群星的转动，而群星事实上在天空中保持不变的模式，是恒定的。所以，正确答案应为C。

D根据第三段的第二句和第三句话，文中说月亮的位置变化相对而言比较快，尽管看起来每天起起落落，事实上它的运动间歇为一个小时。由此可以肯定D为正确答案。

D根据第二段第一句话，太阳沿黄道的运动反映了地球的旋转规律，由此可见太阳的旋转与地球的旋转是相似的。所以正确答案应为D。

A文章最后一句话提到“Because we see the planets from the moving earth，however，they behave in a complicated way，„”，说明行星运行的更为复杂。所以A应为正确答案。

B根据文章的最后一句话，“„their apparent motions on the celestial sphere reflecting both their own independent motions around the sun and our motion as well”可以得出结论那五颗行星的运动也反映了地球的运动。在四个选项中，只有B符合题意，所以正确答案为B。

第五部分：

B系动词is后面缺表语，而这个表语需能说明主语history。

A agriculture是句子的主语，需要填入谓语动词。

E这里后面的句子在语法上已经完整，所以缺的很可能是一个状语短语。

C后面的or提示了这里用either的可能性很大，再看一下either和or后面的两个成分agriculturalraw materials和consumer goods based on them是并列的，便可确认。

D therefore后面跟一in9短语表示结果，这里的therefore相当于thus。第六部分：

文章大意：雪崩是雪掺杂着空气和沿着山体突然迅猛地滑动造成的。雪崩是造成山区人民生命和财产安全的最大危险之一。认真观察地形，注意明显的雪崩路径：没有植物或植物被毁坏的地方。不要在那些可能引发雪崩的人或事物下面行走。

A表达“雪崩是山上可能发生的最大危险之一”的意思，因此应该选择among(在„„之中)。

B从该句的语法结构上来看，此处需要一个关系代词，代替slope，所以that是最佳选择。选项A、C、D均不符合语法。

B选项A不符合语法，c和D符合语法，但不符合常识：过度的雪积压可能导致雪崩，而不是必定导致雪崩。所以，B是最佳答案。

C该句的主语是Determining the critical load，从上下文来看应该使用一般现在时，所以C是正确答案。

C要确定本题答案的一个有效的方法是排除法。a low weight/form work of avalanche都不合逻辑，只有a low risk of avalanche符合上下文的意思。下面的句子解释了low risk of avalanche的道理，更证实了选risk是正确的。

D第56和第57可以一起考虑。整个句子的意思是：在坡度大的坡上，雪不会大量堆积。在较为平坦的坡面，雪不会轻易滑动。

B(见56)。

B理解该句的意思就不难判断选项：雪在静止状态下，角度在350—450之间，最可能发生人为触发的雪崩。between：在„„之间。

C这个句子说明的是什么样的山坡最易发生雪崩，即，A slope that is flat enough to hold snow but steep enough to ski。flat在此做“平坦”解，与后面的steep形成反义。

A句子中的that is表明，后半部分是对前半部分的进一步说明。所以，这里的选择要根据下文的意思判断。use是最佳选择，整个句子的意思是：山坡坡被滑雪者使用的越多，雪崩就越可能发生。

D尽管选项A、B和D都能和continuous搭配，从全段的内容判断，只有process是最佳选择，因为该段描写的是如何防备雪崩，及如何做好安全措施等一系列问题。

A选项A、B、C都可以与weather搭配，但是根据上下文，只有A最为符合文章的内容。

B选项A不符合句子的意思;C不能和risk搭配;D悖逆符合句子的意思，因为不可能完全消除雪崩的隐患。

C该句主句使用的是被动语态，第二个动词是pay attention t0的被动形式。选项A、B、D均不符合句子的意思。

A该句是作者给出的一系列忠告之一，即认真观察地形，注意明显的雪崩路径：没有植物或植物被毁坏的地方。选项B、C、D均不符合句义。

Micro-chip research center created A research center has been set up in this far-east country to develop advanced micro-chip production technology.The center, which will start out with about US$14million,will help the country develop its chip industry without always depending on imported technology.The center will make use of its research skills and facilities to develop new technology for domestic chip plants.The advent of the center will possibly free the country from the situation that it is always buying almost-outdated technologies from other countries, said the country‟s flagship chipmaker.Currently, chip plants in this country are in a passive situation because many foreign governments don‟t allow them to import the most advanced technologies, fearing they will be used for military purposes.Moreover, the high licensing fees they have to pay to technology provider are also an important reason for their decision of self-reliance.As mainstream chip production technology shifts from one generation to the next every three to five years, plants with new technology can make more powerful chips at lower costs, while plants with out-dated equipment, which often cost billions of dollars to build, will be marginalized by the maker.More than 10 chip plants are being built, each costing millions of U.S.dollars.the majority of that money goes to overseas equipment vendors and technology owners-mainly from Japan and Singapore.Should the new center play a major role in improving the situation in industry, the country admits the US$14million in vestment is still rather small.This country is developing comprehensive technologies.Most of the investment will be spent on setting alliances with technology and intellectual property owners.16The country says that the investment of US$14 million is big enough for developing that country‟ chip industry.A.Right B.Wrong C.Not mentioned 17 That country gives top priorities to developing chips for military purposes.A.Right B.Wrong C.Not mentioned 18Although the licensing fees are not very high, that far-east country cannot afford to pay.A.Right B.Wrong C.Not mentioned Many western countries ban the exporting of the most advanced chip-making technologies to that country to prevent them from being used for military purposes.A.Right B.Wrong C.Not mentioned 20 Currently, almost all the flagship chipmakers in that country are owned by American investors.A.Right B.Wrong C.Not mentioned 21Mainstream chip production technology develop rapidly.A.Right B.Wrong C.Not mentioned 22 More than 10 chip plants being built in that country are an example of self-reliance.A.Right B.Wrong C.Not mentioned

More Than 8 Hours Sleep Too Much of a Good Thing Although the dangers of too little sleep are widely known，new research suggests that people who sleep too much may also suffer the consequences.Investigators at the University of California in San Diego found that people who clock up 9 or 10 hours each weeknight appear to have more

trouble falling and staying asleep，as well as a number of other sleep problems，than people who sleep 8 hours a night.People who slept only 7 hours each night also said they had more trouble falling asleep and

feeling refreshed after a night‟s sleep than 8-hour sleepers.These findings, which DL Daniel Kripke reported in the journal Psychosomatic Medicine，demonstrate that people who want to get a good night‟s rest may not need to set aside。more than 8 hours a night.He added that“it might be a good idea'‟for people who sleep more than 8 hours each night to consider reducing the amount of time they spend in bed, but cautioned that more research is needed to confirm this.Previous studies have shown the potential dangers of chronic shortages of sleep一for instance, one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more.For the current report，Kripke reviewed the responses of 1，004 adults to sleep

questionnaires，in which participants indicated how much they slept during the Week and whether they

experienced any sleep problems.Sleep problems included waking in the middle of the night，arising early in the morning and being unable to fall back to sleep，and having fatigue interfere with day-to-day functioning.KriDke found that people who slept between 9 and 10 hours each night were more likely to report experiencing each sleep problem than people who slept 8 hours.In an interview, Kripke noted that long sleepers may struggle to get rest at night simply because they spend too much time in bed.As evidence，he added that one way to help insomnia is to spend less time in bed.“It stands to reason that if a person spends too long a time in bed, then they‟ll spend a higher percentage of time awake.”he said.23Paragraph 2 _E__.24Paragraph 4_B__.25Paragraph 5__A_.26Paragraph 6__D_.A.Keprike‟s research tool B.Dangers of Habitual shortages of sleep

Stress Level Tied to Education Level

People with less education suffer fewer stressful days, according to a report in the current issue of the

Journal of Health and Social Behavior.However, the study also found that when 1ess-educated people did suffer stress it was more severe and had a larger impact on their health.From this, researchers have concluded that the day-to-day factors that cause stress are not random.Ⅵr11ere you are in society determines the kinds of problems that you have each day, and how well you will cope with them.The research team interviewed a national sample of 1.03 1 adults daily for eight days about their stress level and health.People without a high school diploma reported stress on 30 percent of the study days，people with a high school degree reported stress 38 percent of the time，and people with college degrees reported stress 44 percent of the time.„Less advantaged people are less healthy on a daily basis and are more likely to have downward turns in their health。‟”lead researcher Dr.Joseph Grzywacz，of Wake Forest University Baptist Medical Center, said in a prepared statement.“The downward turns in health were connected with daily stressors.and the effect of daily stressors on their health is much more devastating for the less advantaged.”

Grzywacz suggested follow-up research to determine why

less-educated people report fewer days of stress when it is known their stress is more acute and chronic.“If something happens every day, maybe it‟snot seen as a

stressor”Grzywacz says.“Maybe it is just 1ife.”

Stress level is closely related to B)social status.32The 1.03 1 adults were interviewed A)on adaily basis for 8days.33 Which group reported the biggest number of stressful days?

D)People with college degrees.34The less advantaged people are，the greater

A)the impact of stress on their health is.35Less—educated people report fewer days of stress possibly because C)stress is too common a factor in their life.Superconductor Ceramic(陶瓷)An underground revolution begins this winter.With the flip(轻击)of a switch,30,000homes in one part of Detroit will soon become the first in the country to receive

electricitytransmitted by ice cold high performance cables.Other American cities are expected to followDetroit's example in the years ahead, which could conserve enormous amounts of power.The new electrical cables at the Frisbie power station in Detroit are revolutionary becausethey are made of superconductors.A superconductor is a material that transmits electricity withlittle or no resistance.Resistance is the degree to which a substance resists electric current.Allcommon electrical conductors have a certain amount of electrical resistance.They convert atleast some of the electrical energy passing through them into waste heat.Superconductors don't.No one understands how superconductivity works.It just does.Making superconductors isn't easy.A superconductor material has to be cooled to an extremely low temperature to lose its resistance.The first superconductors, made more than 50years ago, had to be cooled to-263 degrees Celsius before they lost their resistance.Newersuperconducting materials lose their resistance at-143 degrees Celsius.The superconductors cable installed at the Frisbie station is made of a ceramic material thatcontains copper, oxygen, bismuth(铋), strontium(锶), and calcium(钙).A ceramic is ahard, strong compound made from clay or minerals.The superconducting ceramic has beenfashioned into a tape that is wrapped lengthwise around a long tube filled with liquid nitrogen.Liquid nitrogen is super cold and lowers the temperature of the ceramic tape to the point where itconveys electricity with zero resistance.The United States loses an enormous amount of electricity each year to resistance.Becausecooled supercondUutors have no resistance, they waste much less power, other cities arewatching the Frisbie experiment in the hope that they might switch to superconducting cable andconserve power, too.36What is the benefit of the revolution mentioned in the first paragraph? C.Great amounts of power can be conserved.37Compared to common electrical conductors, superconductors__________ A.have little or no electrical resistance 38 At what temperature does the superconducting ceramic lose its resistance__________? A.-143 degree Celsius.39 What element enables the ceramic tape to lower its temperature__________? B.Liquid nitrogen.40According to the last paragraph, which of the following statements is NOT true__________? D.The Fribie experiment is not successful.The Science of the Future

Until recently, the “science of the future” was supposed to be electronics and artificialintelligence.Today it seems more and more likely that the next great breakthroughs intechnology will be brought through a combination of those two sciences with organic chemistryand genetic engineering.This combination is the science of biotechnology.Organic chemistry enables us to produce marvelous synthetic(合成的)materials.However,it is still difficult to manufacture anything that has the capacity of wool to conserve heat and alsoto absorb moisture.Nothing that we have been able to produce so far comes anywhere near thecombination of strength, lightness and flexibility that we fred in the bodies of ordinary insects.Nevertheless, scientists in the laboratory have already succeeded in “growing” a material that has many of the characteristics of human skin.The next step may well be “biotech heartsand eyes” which can replace diseased organs in human beings.These will not be rejected by thebody, as is the case with organs from humans.The application of biotechnology to energy production seems even more promising.In1996 the famous science-fiction writer, Arthur C.Clarke, many of whose previous predictionshave come true.He said that we may soon be able to develop remarkably cheap and renewablesources of energy.Some of these power sources will be biological.Clarke and others havewarned us repeatedly that sooner or later we wi/1 have to give up our dependence on non-renewable power sources.Coal, oil and gas are indeed convenient.However, using them alsomeans creating dangerously high levels of pollution.It will be impossible to meet the growingdemand for energy without increasing that pollution to catastrophic(灾难性的)levels unlesswe develop power sources that are both cheaper and cleaner.It is attempting to think that biotechnology or some other “science of the future” can solveour problems.Before we surrender to that temptation we should remember nuclear power.Only a few generations ago it seemed to promise/imit/ess, cheap and safe energy.Today thosepromises lie buried in a concrete grave in a place called Chernobyl, in the Ukraine.Biotechnology is unlikely, however, to break its promises in quite the same or such a dangerousway.41According to the passage, the science of the future is likely to be__________ B.biotechnology 42 Organic chemistry helps to produce materials that are__________ C.not as good as natural materials 43 According to the passage, it may soon be possible__________ D.to make artificial hearts and eyes 44In 1996, Arthur C.Clarke predicted that__________ B.oil, gas and coal could be repeatedly used in the future.45 What do we learn from the last paragraph__________?

C.Biological power may not be as dangerous as nuclear power.五、补全短文(共1题，合计10分)补全短文
