本文介绍了两种不同对待儿童应用计算机的观点，前者认为弊多，后者认为利多．究竟哪种观点对，请阅读下文．

　　We are already familiar with computers-computers work for us at home, in offices and in factories. But it is also true that children today are using computers at school before they can write. What does this mean for the future? Are these children lucky or not?

　　Many people who do not know about computers think of them as machines that children play with. They worry that children do not learn from experience but just from pressing a button and that this is not good for them. They think children are growing up not knowing about the real world.

　　But people who understand more about computers see that computers can be very good for children. A computer can help them to learn about the real world more quickly, to learn what they want to learn and to think for themselves. And for the future, don't we need people who can think clearly, who know how to get information quickly and use it well?

Since 1946, one of the most important inventions has been the computer. It  1   changed our lives greatly.

The first computer was built  2  1946. It was as   3   as a room and very difficult and slow to use. But since the invention of silicon "chip"(硅片), computers have become smaller, easier and   4  to operate. Some computers are as small as TV sets. Some can   5  be made smaller than a book. And computers are getting smaller and smaller all the time. Who knows what the computers of tomorrow will be   6  ?

There are several   7  why the computer is useful to us. First, a lot of information can be put into computers. Second, the computer works very quickly—  8  times faster than a man—and it will not be   9  . Third, modern computers can be built into other kinds of machines, like radios, cars and planes. So today people can spend less time   10  more work with a computer.
