Jim is one of my close friend. Two months before, his mother bought a computer for him as a birthday present. She hoped Jim will study hard with the help of the computer. To her surprise, Jim just spent a plenty of time play computer games every day. He was interested them. Now he regrets buying the computer. As the matter of fact, a computer can do a lot of everyday jobs for us. It is wide used in factories, hospitals, banks and so on. Many computer scientists are now trying to make the computer “think” like a man. In my opinion, the key is what we should use it wisely.
