The computer is a product of advanced civilization and its invention, according to some people, signals the advent of a Second Industrial Revolution. Formerly a bulky machine that demanded much space, the computer is now becoming smaller and smaller and scientists have made it more sophisticated and accordingly more useful. As is generally known, the computer can do a wide range of work, including complex computation and analyses. People now also use it as a teaching aid in designing. An infinite variety of software can be put into the computer, which explains why it is so powerful. There is, however, one thing which we should bear in mind: that the computer cannot think but man can. So there need not be any fear that someday the computer will control us and all we should expect is try our best to bring it to perfection. A computer age is not a pipe dream and there will come a day when most of our needs can be met by this wonderful machine.

Nowadays, technology and science develop fast, and computers have become common in families. A lot of families even have
more than one computer. However, with this phenomenon, some problems raised. First of all, computers can release radiation,which is harmful human's body. At the same time,currently, many people work with computers, and computers occupies them a lot of time. As a result, they have no time to exercise their bodies, which lead to many diseases. Second, a lot of students are addicted into computer games. This makes students stop studying and drop their bright future. Otherwise, some computer games need people to pay money. It is also a waste of money. This addiction also can cause family problems. In my opinion, computers are the product of the development of science and technology. It is unrealistic to stop using computers. Therefore,we should use computers scientificly in case of these problems above.
