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 more work, and they can help people to work out many problems they can't do easily. Our country asks everyone to learn to use puters before the twenty-first century, except the old people.
Today more and more families own puters. Parents buy puters for their children. They hope puters can help them improve their studies in school. However, many of their children use puters to play games, to watch videos or to sing. The teachers and parents plain that puters can not help children to study but make them fall behind. So puters are locked in boxes by parents.
In some other countries, even some scientists also hate puters. They say puters let millions of people lose their jobs or bring them a lot of trouble. Will puters really bring trouble to people or can they bring people happiness?
It will be decided by today's students themselves!
