Jimmy is one of my closely friends. Two months ago, his mother bought a computer to him as a birthday present. She hoped Jim will study hard with the help of the computer. To his surprise, Jimmy just wasted plenty of time play computer games every day. Now she regrets buying the computer. As 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 computers scientists are now trying to make the computer to “think” like a man. In my opinion, the key is what we should use it wisely.
