篇一：
The computer is widely used in all phases of society. In industry, business, education, medicine, nearly all walks of life, computers have made their appearance, providing great speed and accuracy(精确度) for our work. Computers have been used in the home, offices, laboratories and research institutions, functioning as the most efficient and versatile(通用的) instruments for calculating, sorting, filing, recording and distributing. Computers are indispensable(不可缺少的) to modern civilization. Without computers, our life and our society will undoubtedly suffer a big regression(后退).
During the past five decades the computer has been rapidly advanced. Ever since the computer came into being, it has experienced the development of several generations, which are based respectively on vacuum tube(真空管), transistor(晶体管) and integrated circuit(集成电路). Early computers were of great size, and had no match for the latest electronic computers in speed and accuracy. The Latter is capable of processing the most complicated information and reaching solution to problems in a fraction of time. At present, efforts are being made not only to bring the hardware to perfection, but also to improve the quality of the software.
Computers must be instructed and programmed by people. In spite of the remarkable skill of the computer, men can never become its slave. Computers are not creative. They work according to men's instructions. So the development of computers and their use will depend upon the ingenuity of men. Although there are times when computers seem to operate like a mechanical “brain”,their achievements are not comparable to what the minds of men are able to do.
篇二：
How Does the Computer Change Our Life
With the development of science and technology, people depend more and more heavily on the computer. Then how does the computer affect our life?
On the one hand, it can be very helpful to people who need it and treat it corTectly. The computer can broaden our knowledge about the world. It can also help us learn more about many fields of studies quickly: science, medicine, arts and so on. It is very convenient to people who are busy with their jobs, and has brought about many positive changes in our lives.On the other hand, the computer may bring about some negative changes. For example, many children become so addicted to computer games that they stay up late frequently and even neglect their studles. Another disadvantage is that computer's radiation is harmful to people's eyes, especially to children's.
Just as every coin has two sides, the computer has advantages and disadvantages. I think that if we can overcome its negative effects, we can bring it into full play.
