Computers are useful machines. They can help people a lot in their daily life. For example, They can help people to save much time to do much work, and they can help people to work out many problems they can’t do easily. Our country asked everyone except the old people, to learn to use computers before the twenty-first century.

Today more and more families own computers. Parents buy computers for their children. They hope computers can help them improve their studies in school. Yet, many of the children use computers to play games, to watch videos or to sing karaoke, instead of studying. So many teachers and parents complain that computers can’t help children to study but make them fall behind. So computers are locked in boxes by parents.

In some other countries, even some scientists also hate computers. They say computers make millions of people lose their jobs or bring them a lot of trouble.

Will computers really bring trouble to people or can they bring people happiness? It will be decided by today’s students themselves!
