　　In a car-factory computer tells the robots how to do with the cars.

　　Computers are very useful. So many parents buy computers for their children. They hope computers can help them improve their studies in school, but some children don’t do as what parents want them to do. Because they used the computers for surfing on the Internet and spend too much time playing computer games instead of learning. It does not good for their eyesight. So their parents complain about computers not help children to study but also make them fall behind.

　　In many companies computers instead of workers to work. So many people lose their jobs. So many workers think computers bring them a lot of trouble.

　　If computers are good for us or bad for us it’s hard to say so I hope computers will be used in the right way.
