课文背诵段落 Unit 5

These reflections have occurred to me because I read in this morning’s paper that Edward Hyde Burton had died at Kobe.He was a merchant and he had been in business in Japan for many years.I knew him very little, but he interested me because once he gave me a great surprise.Unless I heard the story from his own lips, I should never have believed that he was capable of such an action.It was more startling because both in appearance and manner he suggested a very definite type.Here if ever was a man all of piece.He was a tiny little fellow, not much more than five feet four in height, and very slender, with white hair, a red face much wrinkled, and blue eyes.I suppose he was about sixty when I knew him.He was always neatly and quietly dressed in accordance with his age and station.Unit 6

Once upon a time, technology, we thought, would make our live easier.Machines were expected to do our work for us, leaving us with ever-increasing quantities of time to waste away on idleness and pleasure.But instead of liberating us, technology has enslaved us.Innovations are occurring at a bewildering rate: as many now arrive in a year as once arrived in a millennium.And as each invention arrives, it eats further into our time.The motorcar, for example, promised unimaginable levels of personal mobility.But now, traffic in cities moves more slowly than it did in the days of the horse-drawn carriage, and we waste our lives stuck in traffic jams.Unit 7

Long before the Boeing brought down the towers, poet Percy Bysshe Shelley wrote “grief return with the revolving year.” So it is with New York.The time it took the Earth to circle the sun was time enough to clear the wreckage, but not enough to fade the memory of what happened there.It was time enough to plan memorials, but not enough to fill the gaping wound in lower Manhattan.For what is a year but a thin sliver of history, a beat of a hummingbird’s wing?

CLOZE

You see that young man swimming out at sea? He’s trying to swim out to the beacon and back.He must be insane to have committed himself to such a ting.The current is far too strong.To be candid, I wouldn’t attempt it.I dare say few swimmers are capable of such a feat.I met him on the beach before he set out.I don’t mind what he was going to do, because he didn’t look in good condition at all.Far from it.He may have had a good constitution once, but he had clearly let himself go all to pieces.However, it seems like he had no choice.He told me that he had gone broke, not a penny left, and that old Burton would only find him a vacancy in his firm if he did the swim.That was another surprise.Burton seems such a mild-mannered man, kind to everybody.Perhaps he thought the young man would not have the courage, that he would funk it.Then, again, perhaps Burton knew he was sending the young man to his death, but was too cold-blooded to care.It only goes to show how deceptive appearances can be.Can you switch off form the cares of life and relax? Many people cannot.They feel instead that they are obliged to be on the go all the time.The pace of life seems to grow ever faster.As the result, feelings of stress are common as people struggle to cope with what they see as a shortage of time.Such widespread feelings are in part caused by the large quantity if information that comes pouring in on us.“All man,” said Aristotle,” “by the nature desire to know.” But it is no longer possible, as it was in the past, for an individual to master the whole range of human knowledge.Instead, any individual, no matter how smart he is, can only command a fraction of total knowledge available.It may be argued that it is futile to even attempt to do so.We should learn to set more realistic goals for ourselves if we are to hope to escape from the tyranny of time.Corky Siemaszko’s snapshots provide us with an insight into the mood of the American people following in the tragic events of 9/11.they start with two pieces written in the immediate of aftermath of the attack.These clearly reveal the state of chaos into which New Yorkers felt they had been plunged by the toppling of the twin towers.Balancing widespread feelings of shock came the welling up of a strong sense of solidarity with each other in the face of a common enemy.Together with this came a natural desire to take revenge on those responsible.A year later the snapshots reveal a city and a nation thinking back on the fateful events of 9/11 while mourning those who perished in the attacks.Vocabulary

In a way refer shopping online because it is more convenient and saves time.The success of mechanics in discovering reliable and useful laws of nature suggested to Galileo that all nature is designed in accordance with mechanical laws.A vacancy exists for a sales manager at our Paris office.If you’re interested in it, please send us an application letter and your resume at once.If you are over 18 and in good condition, it’s completely safe to do the job.Plastics can be made hard as stone, strong as steel, transparent as glass, and light as wood.Coat the shoes with polish, the hitherto hard with a soft cloth to give a shine.It was probably just a spicy joke to them, but it wasn’t funny to me at all.Michael’s praise for my wife opened my eyes and taught me to show gratitude for her day-to-day heroism, which I had hitherto taken for granted.The waitress did bring us clean plates eventually, but with a bad grace.Some scientists believe that human beings are born with an instinct for using their arms and legs to stay afloat, which however, disappears within a few months after birth.In order to pay the bills, Linda pawned her grandfather’s gold watch in secret.Fish instinctively fight their way upstream against the current, and many water birds and animals have the ability to travel long distances.Streamline by nature comparative decorate distribution bewilder convention famine fax multiply prosperity appliance toil point the way to sth cope a large quantity of

第三篇：英语期末

英语(期末复习)第一章

1.According to many historians,the true pioneers of the modern digital computer are Charles Babbage and Augusta Ada Byron.2.A digital computer is generally made up of five distinct elements: a central proccessing unit, input devices, memory storage devices, output devices,and a bus.3.The microprocessor is a central processing unit on a single chip.It was made possible in the mid-1970s with the introduction of the LSI circuit and the VLSI circuit.4.According to the text, modern digital computer can be divided into four major categories on the basis of cost and performance.They are microcomputers, workstations , minicomputers,and mainframes.5.The first electronic computers, such as Colossus and ENIAC created in Britain and the United States respectively,used vacuum tubes, which later gave place to transistors.6.A program is a sequence of instructions that can be executed by a computer.It can either be built be built into the hardware or exist independently in the form of software.7.The smallest unit of information handled by a computer is bit, which is the abbreviation of binary digit , A group of eight bits makes up a(n)byte.8.One of the trends in computer development is microminiaturization ,the effort to computer more circuit elements into smaller and smaller chip space.第二章

1.The function of computer hardware is typically divided into there main categories.They are input;, output ,and storage.2.The software that controls the interaction between the input and output hardware is called BIOS, which stands for Basic Input/Output System.3.The two most common types of scanners are flatbed scanners and hand-held scanners.4.Video displays commonly task one of two forms, they are CRT-based screens and LCD-based screens.5 In the text,the author mentions thess of the most commonly uesd types of printers.They are_dot-matrix printers_,laser printer,and__inkjet printers _.6

According to the text,the two main types of

storage devices are_disk drives_and_memory _.7 It can be said that having a steady power source is important for a computer because RAM is_volatile_memory.8 A(n)_serial_connection transfers only one piece of data at a time while a(n)_parallel_connection transfers blocks of information at the same time.第八章

1、According to the geographical area covered ,a computer network is often classified as either a LAN , a(n)MAN ,or a WAN.2、A net work can also be classified as either a(n)open network or a(n)closed network according to whether its internal operation is based on designs in the public domain or on innovation owned and controlled by a particular entity.3、A network can also be classified according to its topology.Among the most popular topologies are the bus topology , ring topology, and star topology.4、A popular protocol in networks based on the ring topology is the token ring protocol developed by IBM in the 1970s.5、In a(n)Ethernet system ,the right to transmit messages is controlled by the protocol know as CSMA/CD.6、The client / server model for interprocess communication defines the basic roles played by the processes as either a client or a server.7、The peer-to-peer model involves two processes communicating as equals and usually executing on a(n)temporary basis.8、Althought it is often used , the term peer-to-peer network is not very appropriate.第十一章 The year 2000 was a turning point in electronic commerce.It maked the end of the “dot-com__boom ___”.2 Most people use the terms “electeonic commerce”

and “electronic__business_interchangeably.3 Based

on the types of participating_entities_electronic commerce can be classified into five categories:B2B, B2B, business processes , C2C, and _B2G__.4

The three most commonly used categories of eletronic commerce and B2C , _B2B__,and business processes.5 In C2C trnasactions, one party is selling, and thus as a business, so they are sometimes treated as part of _B2C_electronic commerce.6

The first wave of eletronic commerce was dominated by_ U.S.或American_companies.7

In the first wave, there was an over-emphasis on creating new large enterprises to exploit eletronic commerce opportunities because of the easy access to start-up_capital.8 The increase in_broadband_connections in homes is a key element in the second wave of electronic commerce.第十二章 1 Accoring to the text, the largest category of computer criminals is _employees_.2 People who gain unauthorized access to a computer system for fun and challenge are called _hackers _.3 People who gain unauthorized access to a computer system for malicious purposes are called _crackers_.4 Computer crime can take the form of damage_theft, and manipulation _.5 A(n)_worm_is a destructive promgram that fills a computer system with self-replicating information, clogging the system so that its operations are siowed or sopped.6 Software piracy_is the unauthorized

copying of programs for

personal gaim.7 Secuity measures for computer system consist of encryption, restricting_access__,anticipating disasters, and making_backup_copies.8 Secret words or numbers that must be key into a computer system to gain access are called_passwords_.英汉互译 第一章

To begin with, I would like to greet the chairperson and my fellow debaters.I am debater 1;this is debater 2, 3, 4.We think that attitude is the major factor that influences our fate.With the growth of age, I am increasingly aware of the powerful influence of attitude to life.As an old saying goes “Attitude determines fate.” It means that no matter what happens, attitude decides everything and the attitude can influent our fate.Moreover, the key to solve problem is our attitude.Only we have a positive attitude towards our problem can we have the courage to overcome these problems and do it much better.For example, Helen Keller, who is blind when she was young, becomes a famous writer and educator because she chooses a positive attitude towards her fate and it helps her overcome the blindness.So we stand on the point of “our fate is linked to our attitude rather than pre-determined.”

反方一辩：

Good morning, everyone.I am debater 1;this is debater 2, 3, 4.Today we are stand on the part of “our fate is linked to pre-determine rather than attitude”.Reasons are as follows.Firstly, destiny now is called fate because it is an objective fact and cannot be changed, if fate can be changed, it is also called the “fate”? Visible, change “fate” is a kind of stultify oneself.No matter what you do, you are guided by a series of rules to do that.Secondly, a person's innate features can determine his work, the NBA no one height is low, and the Olympic champion, their talents are very good.And every scientist was born very clever.All of these are pre-determined rather than attitude.Lastly, a good pre-determined fate plays a important role in their success.Of course, we cannot deny that some people make success on their own.But we also cannot deny that many people get success easily because their fathers are very rich so as to they have a good fate.So, we say that our fate is linked to pre-determine.正方二辩向反方一辩提问：If fate is pre-determined, why we need to work hard? We needn’t do anything because everything is determined.反方一辩答: The opposite debaters may not understand the meaning of “fate”.The fate is so uncertain that we cannot know all the vicissitudes of our fortunes and what we can do is change now.So we have to work hard for a living or change family life.正方二辩向反方三辩提问：As is known to all, there are many people achieve success because they have a positive attitude in the world but they are from a poor family.How to explain this situation? 反方三辩答：This situation just shows that fate is unpredictable and has nothing to do with attitude.No matter we have a good or bad fate, we cannot know until it happens.And we also don’t know whether they would be successful until they achieve success or die.反方二辩向正方一辩提问：The opposite debaters say that fate is linked to attitude, that is to say if you have a positive attitude, you will have a bright fate? 正方一辩答：We never say a positive attitude must give people a good fate but no one can deny that having a good fate need a positive attitude.反方二辩向正方三辩提问：In Britain, they have the Prince and Princess.What do you think of the prince and princess;they are born with good fate, aren’t they? 正方三辩答：They just have a good birth, but not a good fate.In ancient China, a lot of prince even kings have a bad fate.反方二辩小结：

At this part, the opposite debaters state that a positive attitude can lead to a good fate but now we argue about the relationship between the fate and attitude or pro-determine.We must understand truly what the fate mean.It is not controlled by people and full of variables.Nothing can influent fate include people’s attitudes whether positive or not.So we still believe that our fate is link to pro-determine.正方二辩小结: First, a positive attitude promotes a good fate and a negative promotes a bad.It shows the relationship between fate and attitude.Second, the human development is the objective course of changing fate from the “history” to “future”.No matter you have a good birth or not, the fate is in your hand and it is determined your attitude.二、自由辩论

正方二辩问: As is well known, Beethoven is deaf but he also creates many famous songs because he clutches at the throat of fate through his positive attitude.What do you think of it? 反方三辩答: It just shows Beethoven have an ear for music and it is pre-determined so as to he can become a famous musician.正方三辩问：Can he achieve success only by having gift? 反方二辩答：Of course not but talent is the most important.As Edison said that genius is one percent inspiration and ninety nine percent perspiration, but the more important is the one percent.反方三辩问：How do you think of genius? Isn’t their fate linked to pre-determine.正方四辩答：Genius has a good talent but they may not have a good fate.Many people performance well in their childhood but they don’t have a good future when they grow into adult.反方四辩问：But their good performance when they are young is the reflection of our opinion, isn’t it? After all, children don't know what is attitude.正方三辩答：So what? It is just a piece of life and their future is doubtful.There is no doubt that their fate is linked to their attitude.三、总结

正方四辩：

As a wise man says “Life is a difficult journey which we cannot choose the beginning but can choose the ending”.We must believe that we change our fate when we have a positive attitude towards it.No matter you are from rich or poor, you can achieve success in any fields just as Fleming and Churchill, a poor chemist and a wealthy politician.Furthermore, attitude makes a difference in problem even illness.Previous research has shown that a positive attitude help to cure illness even slow death, which means it change our fate.All in all, we think the fate is linked to attitude.反方四辩：

First of all, fate is pre-determined and irreversible.We cannot know what will happen in future.Secondly, there is no doubt that people who have good background achieve success easily compared with the poor.It is pre-determined and no one can change it.Last but not least, many jobs need people’s talent such as sport.A good talent can make it easier to get job and this is also pre-determined.So we support for fate is pre-determined.

Translation U1 六年前，作者经历了一场惊险的旅程。这次经历让他印象深刻，因为他在这场紧急的事故中找到了真正的英雄。一个周五的早上，航班前往亚特兰大。飞机起飞不久，飞行员向乘客通报紧急情况：一个引擎失控了，液压系统已经失灵了。更糟糕的是，他们都将会坠机。忽然间，机舱里一片恐慌。许多乘客脸色苍白，四周都在哭喊。在混乱中，一把温柔冷静的妇女声音传来，她正在安慰自己的女儿。母亲似乎没有被四周的悲伤和恐惧影响。即使面对死亡，她依然坚定的告诉女儿她有多么爱她，她把女儿包裹在怀里，尽可能的保护她。幸运的是，飞机安全着陆。母亲对女儿的那份爱向人们展示了什么是真正的勇气。

The author went through a breathtaking travel six years ago and the experience impressed him deeply because he found a real hero in that emergency.On one Friday morning, a flight headed for Atlanta.Soon after the plane took off, the pilot announced the urgent crisis that one engine was broken and the hydraulic system had failed.Worse still, they might be about to crash.Suddenly, panic spread all over the crowd.Many passengers lookgrim and pale.All around, people cried and screamed.In the chaos, there was a soft and calm voice from a woman who was trying to comfort her daughter.The mother seemed undisturbed by the sounds of grief and fear around her.Even when facing death, the mother still told her daughter firmly about how much she loved her, and put her body over her daughter, trying to protect her as much as she could.Fortunately, the plane landed safely.No one was hurt in the emergency.However, the mother’s love for her daughter showed people what real courage was.U2 我告诉他，我绊倒在地时听到了撕裂声。然而我的丈夫，不但不理会我说的，而且声称，一定是我的鞋带问题。所以，即便我的脚肿的像个气球，但我们并不知道我的脚崴了，因为他没有送我去看医生。在去机场的12个小时的飞行中，他把我一个人扔在借来的轮椅上，完全没有注意到我要去洗手间的手势。

I told him that I heard a snapping sound when I stumble and fell.But he, my husband, not only dismissed what I said but also contended that it must have been the strap on my shoes snapping.Therefore, we didn’t know my foot was broken because he didn’t send me to a doctor even though my foot was swollen like a balloon.During the 12-hour flight to the airport, he left me alone in the borrowed wheelchair and pretended that he didn’t notice my gestures indicating the need of going to the bathroom.U3 你可以找到缓解压力的方法，并很快重新掌握自己的身体。你也可以学会如何先使身体放松，随之带动精神放松。你也可以学看如何放松精神进而掌控自己的工作状态。一旦压力消退，人们就会很快解决工作中出现的问题。

This day, as I entered my class, some gossip came into my ears.It was about a new freshmangirl from China, who aroused my curiosity.I wanted to meet the mysterious figure and I did.The Assistant Dean called me over to take the girl to her afternoon activity.So we started our journey.The first stop was her dorm.Half of the room was so tidy that it was hard to tell whether there was existence of human beings.The other half was totally a mess.Of course, the neat half belonged to the Chinese girl.U5 我们所拥有的资产会快速贬值的原因是一旦我们已经拥有了，就会对之失去兴趣。在这种情况下，我们就可以用这些物品进行合作消费。相关研究人员告诉我们传统的分享已经变身为租赁业务，并将在未来十年中蓬勃发展。考虑到人口的快速增长，集体消费将完全符合“资源共享，以物易物，贸易，租赁”这一新的趋势。在进行合作消费时，如何理顺合作关系将成为最具挑战的问题：在同一时间，人们都需要同一件物品怎么办？在这个资源越来越少的世界，我们别无选择，只能与他人，甚至陌生人一起分享财富，这未尝不是一个明智的选择。The reason why the value of the assets we possess depreciates quickly is that we already have the ownership and we may lose interest in them.Under this circumstance, these items can be used for collaborative consumption.The relevant shows us that traditional sharing already transformed into rental business which will thrive in the following decade.Considering the growth of population, collaborative consumption conforms to the trend– sharing, bartering, trading and renting.The biggest challenge of collaborative consumption is streamlining operations because people may need or want the same item at the same time.In this on-going world with resources which are declining in amount, we have no choice but to collaborate with others, even strangers to spread the wealth.
