Unit 3 How science changes our lives
王璐 （法律）
As the world develops, technology and science changes our lives in more and more fields. We use modern machines in factories, enjoy music and programmes at home with modern electric equipments. One of the developments most likely changed ( that change our lives most) is the technology of the internet (Internet).
Nowadays, the Internet is being widely used. Students make use of the Internet to study in the (/)school, office workers use it to search for information, in the field of the (/) agriculture, we also use it to control the temperature in the greenhouse. The Internet entertains people as well. Many people listen to music and see films on the net. Some others enjoy the Internet games very much. Besides, with the help of the Internet, we can communicate with others more conveniently. We can chat with friends from every part in the world on the net.
In a word, the internet, as well as other science and technology, changes our lives, no one can prevent these changes, what we can do is to(/) ensure that the changes they make are in the right direction. 张浏
Whether we admit it or not, the (/) science has changed a great deal of our lives. Look around! The food we eat, the clothes we wear, the machines we use, obviously they all depend on modern science.
Take computers, for example. Maybe it is one of the most greatest inventions in the 20th century. Now with the help of computer, you can get information much more faster, and as it is said, the globle (world) is becoming smaller and smaller, the distance of people is becoming closer and closer. You don’t need to spend a lot of time going shopping or going to work, the Internet will help you a lot. Much work is done by the clever computer, and people can lead a(n) easier and happier life.
This is only a small example that (of) how the (/)science changes our lives. I believe in the future the standard of living will be increased steadily with the development of modern science. 叶斌
I’ve been anticipating a computer of myself (my own) for a long time, although it hasn’t (been) realized yet. Why? I ask myself for many times, why could such a small object draw all my attention? Maybe, there is only one answer. “It’s because that computers make our life more and more colorful!”
With computer, workers could save much more time and strength in managing machines; teachers could have more convenient ways in exchanging (ideas) with students; families in different places could have another way of conversation; businessmen could manage their company(ies) at home and don’t have to travel all over the world…
Computer is playing a so (such a or so important a) important part in our daily life that someone (some) even begin to fear that, someday, human itself will be substituted by it. And we have to realize that it is changing our world and our lifestyle gradually, and gives us another way of working, conversation, living and even the method of thinking.

But, as we can see, all things have two edges (sides), and so does computer, especially when the Internet is developed. Some students are lost in online game, more and more impositions happen, causing the crisis of credit. Time for sports, for outing is cut down…
Computer is changing our life and the world rapidly. Although it has the unpleasant side, we could not prevent it from making the world different. We can’t do without it, even just for one day. The only thing that we can do is to (/) ensure that we could control ourselves not to be lost, and make sure that the change is in the right direction. I have sufficient faith that, under control, computer will make our life more and more colorful, exciting and enjoyable. 谢勇元
It is a truth that nobody can deny that science has changed our lives greatly and will always change. (It is an undeniable fact that science has changed our lives greatly and will go on changing them.) Because we can find out enough witnesses (evidence) during lives (/) to prove it.
Electricity, in my opinion, is one of the most important inventions. Before the electric time, most people had to live hard lives, and even including a privileged minority live tedious lives as dull as ditch water. But now, it is different. We can watch TV, enjoy CD, know news at first time (get the latest) and so on. In my case, what make (s) our lives colorful is electricity.
At the atom age, the rate, increasing in (/)our standard of living quickened evidently. But in the meantime, more and more people began to blame science and technology for atomic weapons, because the atomic weapons would destroy the earth. I don’t agree (with) them, because I think atomic weapons were made by ourselves. It has nothing to do with(is not the fault of) science and technology. (Rather, it) It’s human fault.
Now, we are entering a new age. Genetic engineering is changing our lives. I hope human will become much wiser, will make good use of science and technology to increase in (/) the standard of living.

with the rapid development of science and technology, our daily life is much more enjoyable than before. We can relax ourselves anytime by electric appliances like radios, televisions and video system. Those labor-saving machines such as washing machine, microwave oven and dish washer free people from house chores, thus people have more leisure time to enjoy the life.
The development of transportation brings people a lot of convenience. Trains, buses and air planes can take people to any place in the world.
Science has also promoted the advance of education. The development of computer science and information technology make it possible for students to receive education without going to school they get information through particular network. They hand in their paper(s) and talk with their teachers by e-mail. In conclusion, science has brought and will brought (bring) about many great changes in our lives. 周竞琛
As Stephen Hawking says, whether we like it or not, the world we live in has changed a lot. And most of these changes are based on the development of science and technology.

For example, the widely (wide) use of computers has changed our lives. A person can easily communicate with others just sitting in front of the screen, pressing keyboards. Everyday, there are many things available on the internet (Internet). People can be informed of the news as soon as they happen. People also can buy things, enjoy music, learn things on the internet. It means that people can know everything without going out.
Moreover, computes plays an important role in many fields such as education, research and military affairs, etc. Suppose there were no computers, how could we send Shen Zhou Five to the space?
But every coin has two sides. Science also brings many troubles to us. Like computers, we have to face the problems like (such as) computer virus, and the security on the internet or so (/). If these problems can’t be dealt with properly, they will bring bad results (effect) to human beings.
In my opinion, science can make our lives better, also worse. We should try to prevent bad things and make good use of science to improve our living standard. 沈希
Science has brought much benefit to our lives and has completely changed our daily life. Genetic engineering makes our food much healthier; air-conditionings make the air much cleaner (us fell more comfortable in scorching summer); cars and planes make it much more convenient for us to travel; TV sets and computers make us tightly (closely) informed of the last (latest) news; spaceships make it possible for human beings to explore the outer space. Without these things we would certainly fail to do most things in our daily life. In the old time, people were threatened by many kinds of diseases which can be easily killed today. A kind of pestilence (plague) can destroy even a big country! With the development of science and technology, our living standard has been greatly improved and we live much happier and safer than our ancestors.
Every coin has two sides. Science may also bring us disaster, if we failed to control it. But we should have faith in that we could manage to ensure (have faith that) that the changes science make are in the right directions. 姜芳
Human life can not continue without science and technology. For many centuries, human society develops with the advance of science and technology. So the life we are living now is more civilized, comfortable than that of our ancestors.
For example, scientists (do) research (on) useful medicine to control some deadly diseases; they devise better methods of agriculture, industry and business; they also turn poor soil into rich land; they develop atomic energy which can provide us with large amount of electricity. But in my opinion, the biggest change taking (taken) place in our life is that the world becomes (has become)smaller.
Today, almost every common family owns a television. Over 100 years ago, knowing the events happening far away or the foreign culture was a difficult task for most people. Now TV, radio and computer change that. We can easily get the information about everything, everywhere in the world, which is clear, speedy and as much as possible (and…/). The opposite side of the earth is like your neighbor. The whole world turns to a village! Besides this, you may not be (feel ) so bad to be (/) parting with someone.

You can hear them through the phone; even more you can see them on the computer screen. It is just like you are never parting.
Sometimes, I feel that science is a benefactor for all of us. As long as it is not wrong(ly) used, it will always help us to contribute, to master and to develop. 沈苑如
With the development of economy and the improvement of science and technology, the world has witnessed great changes in our daily lives. Modern science brings us benefits and harms at the same time. Take an example, computers make our lives more efficient. It can do whatever human beings can’t do in a convenient way. Moreover, it help（s） human beings earn much time and it can do some tedious work while （but）it won’t feel boring. However, some people who want to make benefits for their own make use of computers to destroy world peace and to commit crimes.
They create robots to control their minds. They are so good at the Internet that they will be the Hackers to enter the control centers of government or some institutions and companies to destroy their systems. Above all, science has changes(d) our lives greatly. Despite its harm, I firmly believe that the world will become better and better by the aids of advanced science. 肖力铭
It is no doubt that science is changing our lives almost everyday. The changes bring us not only many conveniences but also some damages.
The transportation, for example, has changed greatly in the last century. If a man want(ed) to visit New York from Shanghai about 100 years ago, he would have to take at least two months to get to the destination by sea. And if it happens nowadays it only need(s) several hours to let the man arrive in New York by air. Compared with the two situations, we can obviously see the benefits which science brings us. With the development of science, our lives have changed a lot, and the changes take place more and more quickly.
Every coin has two (surfaces) sides, except the good changes there also remains some unpleasant ones such as the acid rain. Our earth is damaged seriously, which cause(s) the environment (to) become worse and worse. All those changes were brought by the development of science.
On the whole, science brings more beneficial changes to our lives than the unfavorable ones. If science (is) develop(ed) in a correct way, there will be less damages (damage) to our lives. 张引
As science develops faster and faster, we benefit more and more from it. Just look around, you can easily find that almost everything in your sight has changed our lives more or less, for example, as big as the car, the plane, the computer, as small as the pen, the light etc. It can’t be denied that science makes our lives more and more convenient. But as every coin has two sides, science also brings us harm in the meantime it brings us good.
Take nuclear power for example, maybe the original purpose is to solve the resource (energy) shortness (shortage), but it brings enormous destruction to our lives as it is used in the war. It is also a change, of course, though we do not expect to see.

But we can’t hold back (up) science just because it may bring us harm. Whatever effects it has, one thing is certain, science in itself is neither good nor bad. It is the uses to which it is put the(/ )that determines its value to society. 霍文宇
Science has greatly changed our lives. It brings benefits, while it also brings problems.
Computer, for example, have supplied some comfort of working, and studying. Through the internet (Internet), you can work and study just at home. Because of the genetic engineering, new genetically modified crops have brought benefits from higher yields and less use of harmful chemicals. In the future changes are likely to be even much greater because science itself changes much faster and greater.
But we cannot just say that science will only change our lives for the better. It’s possible that computers will take (do) some serious damages to our human beings. Genetic engineering may create some new and terrible diseases. However, we should assure (ourselves that) we could stop these from happening.
So we should know that science has changed and is changing and is going to change our lives greatly.
