任务型阅读 阅读短文完成下列任务。
Computers are becoming more and more popular in our daily life. People like scientists, teachers, writers and students use computers to do all kinds of work. But more than 30 years ago, computers did not do much. They were very big and expensive. Very few people were interested in them and knew how to use them. Today computers are small and cheap. They can do a lot of work, so many people like using them. Most people have them at home.
Computers become very important because they can work faster than men and make fewer mistakes(错误). Computers can help people do a lot of work. Writers now use computers to write. Teachers use them to help teaching.                  and children use them to play games. They are our good friends.
We live in the“computer age.” Everyone needs it.
