Computer and Man
范文一：

It is believed that the computer is bringing the world into a brand new era. At the time the computer was invented, scientists, marveling at its calculating speed, felt that they had created a miracle. Nowadays, the function of the computer is no longer confined to calculation; it permeates people’s daily lives and has become an inseparable part of human society.

People become so heavily dependent on computers that it is hard to imagine the life without computers. Therefore, some people are worried that “The real danger is not that the computer will think like man, but man will think like the computer.”

Their concern does make sense. Indeed, some people spend such a long time working on computers that they have few interactions with people in real life. According to a research, too many hours in front of a computer may lead to a poker face and interpersonal isolation.

Can man be controlled by computers? The answer is negative. Although a computer works much faster and accurately than man , a fact is undeniable; it is designed, manufactured and programmed by man, and therefore by human beings. Of course, science fictions have made up many fascinating stories about a computer, or rather robot, who conquers man and the earth, even the whole universe; however, they are only unrealistic imaginatio. A horse helps man a lot runs much faster than we, but it is only a slave。

The future for the computer is very promising. With the help of it, we can do things that could not be done before. Conquering the universe, discovering new things, explaining mysteruiys phenomena puzzling us at present are all made possible by computer.
