Computers are useful machines. They can help people a lot in their everyday life. For exam

Computers are useful machines. They can help people a lot in their everyday life. For example, they can help people save much time, and they can help people work out many problems they can't do easily: Our country asks everyone to learn to use computers except the old people.
Today more and more families own computers. Parents buy computers for their children.
They hope computers can help them improve(提高) their studies in school. Yet many of the children use computers to play games, to watch video or to sing Karaoke instead of studying. So many teachers and parents complain that computers can not help children to study but make them fall behind. So computers are locked by parents in the boxes.
In some other countries, even some scientists hate computers. They say computers let millions of people lost 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 people themselves.
