Hello, everybody!With the development of scientific technology, our life has become the most convenient than ever before.It is not deniable that we are in the era filled with digital product.For example, we put our photos in digital cameras, we store our assignments and documents in U-disks, and we place our favorite songs in MP3 player.They are all connected and available through computers.Computers are adequately used around the world nowadays, especially college students, but we also should know that computers are overused.People spend so much time working on it, which leads to series of bad effects.I’ve been interested in the bad effects of using computers too much for quite a long time.I’ve searched on Internet and looked up related books in library on this issue.So today I will persuade you to stop overusing computers for 3 reasons.First, it will do harm to your health.Second, it is a waste of time.And third, it will make you lose some of your abilities.First, it will do harm to your health.There are 4 problems at least.According to Wendy Ghannam and Mats Gyllenberg, specialists of computers, the low-energy X-ray and low-frequency electric radiations can cause the imbalance of centered-nerve system.This will cause headache, sleeplessness and other illness.It is the first problem.And the second problem is Carpal Tunnel Syndrome.According to Tammy Crouch.It is nerve damage that results from the repetitive hand motions with constant typing.The symptoms are intense pain and lessened motor control in the wrists and hands.The third one is eyestrain and subsequent vision.According to Irvin E.Houck Center for Information Technology, they result from sitting too close or too far from a computer screen.The forth problem is the pain of body, including muscle stress and back pain.Muscle stress results from extended periods of computer use without breaks.Back pain usually comes about because the computer users don’t sit properly when working.So now that we’ve known the reasons that computers do have harm to our body and health, we move on to my second point------it is a waste of time.I’ve done a research on 51 students in English department of our school.I found on average, that only 1/6 of their time of using computer is learning, such as looking for information doing homework.The rest 5/6 is spent on chatting on line, playing computer games or searching for the meaningless websites or other things.I’ve read in the China Daily in my freshman year that a mother had to lock the computer because her son overused computer and caused the declination of his grade.So most of the people, especially young people lack the self-controlled ability, and make it become inevitable.But it hasn’t over yet.Which brings me to my third point that overusing computer make you lose some of your abilities.You are likely to get lazy and use pen less than ever after you’ve gotten a computer.According to professional women, a published magazine in China claimed that overusing computers might cause reduce of brain function and therefore recession of memory.Second, your handwriting will become worse because of lack use of your pen.Third, probably you will lose the ability of controlling the temper.A survey held by Concord Information Corporation showed that 10% of their customers would act in violence simply due to problems of computer or Internet if they have been working on it for a long time.They couldn’t help breaking the screens, crashing keyboards or mouse when their PCs went wrong.In conclusion, let me summarize my 3 points.First, I told you that overusing computers do great harm on human bodies.Second, it is a waste of time.Third, it makes you lose some of your abilities.So overusing computers is really harmful.In closing, I want to declare one thing, that is: I’m not asking you not to use computers anymore.We have to use it, because it is necessary, a need, a must, for every one of us.But when we use it, we’d better ask ourselves, whether I use it properly, whether I overuse it.Thank you.

actor.But he is never give up!He also spent five hours a day in actor courses, pronunciation courses ,remove accent course and so on.All the things you can imagine, he have to do.Finally, he did!he get more than $ 30 million paycheck in the film “Terminator III”, the highest in the history of the paycheck.He knows what is him realy want at every stage of his life.Now he is the governor of California.Next he may want to be the President of America.There are a lot of people can also stick to their dreams like Edison , Nobel and so on.They make their life is full of surprises and wonders.So , we are young , we have more time to create more wonders than they.We don‟t have nothing pleasant to be worth doing.Conversely ,there is too mach.So , Let‟s calm down and think about it.What is we realy want and where is our dream ? Then hold on!that‟s all , thank you very much!

Ladies and Gentlemen.Good afternoon!I’m very glad to stand here and give you a short speech.My topic today is global warming.At present, humans face a serious challenge.That is global warming.Increasing global temperatures are causing a broad range of changes in the world.Sea levels are rising due to the melting of land ice.As you can see, global warming is a very serious threat to our lives，so it is important to learn more about it.Generally,global Warming is caused by two things.One is man-made, another is natural causes.One natural cause is the release of methane gas from arctic tundra and wetlands.Another natural cause is that the earth goes through a cycle of climate change.This climate change usually lasts about 40,000 years.Man-made causes probably do the most damage.There are many man-made causes.Pollution is one of the biggest man-made problems.Pollution comes in many forms.Burning fossil fuels is one thing that causes pollution.Fossil fuels ,such as coal or oil.When they are burned, they give off a green house gas called carbon dioxide.Another major man-made cause of global warming is population increase.More people mean more food, and more methods of transportation, right? That means more methane because there will be more burning of fossil fuels, and more agriculture.Another source of methane is manure.Animals like cows are raised as a source of food which means more manure and methane.Another problem with the increasing population is transportation.More people mean more cars, and more cars mean more pollution.Also, many people have more than one car.In the past few years, many workers have noted that the combined effect on climate of increases in the concentrations of a large number of exraust could rival or even exceed that of the increasing concentration of carbon dioxide.These exraust, principally methane and nitrous oxide, are present at concentrations that are two to six orders of magnitude lower than that of carbon dioxide, but are important because, per molecule, they absorb infrared radiation much stronger than carbon dioxide.Studies have shown that human activity of this century has increased the concentrations of atmospheric exraust, which in turn has elevated global surface temperatures by blocking the escape of thermal infrared radiation.Natural climate variations are masking this temperature increase, but further additions of exraust during the next 65 years could double or even quadruple the present effects, causing the global average temperature to rise by at least 1 °C and possibly by more than 5 °C.If the rise continues into the twenty-second century, the global average temperature may reach higher values than have occurred in the past 10 million years.However, assessment of ongoing and future climate change requires long-term global monitoring of aerosol properties.So there is a need and opportunity for global cooperation in technology development.Only by doing so that we can better live in this planet.Thank you!
