五、阅读理解。回答下列问题。
Man has made many interesting inventions since the beginning of time. Some of these inventions like numbers,words and radios have certainly changed history.
One of the most important inventions is the computer. It has changed all of our lives. People built the first computer in 1946. It was as large as a room and quite difficult and slow to operate(运行). But since the invention of the silicon chip(硅片),computers have become smaller,easier to use,and faster to operate. Some computers are as small as TV sets. People can make computers smaller than books. And computers are getting smaller and smaller all the time.
The computer can do a lot of work,so it is very useful to us. Firstly,it can keep a lot of news and messages. Secondly,the computer can operate very fast — thousands of times faster than a man,and it won’t be tired. Thirdly,people can build computers into other kinds of machines,like radios,cars and planes.
