The computer is a very good machine(机器). It can do a lot of work every day, so people can use it in many ways. Writers can use it to write interesting stories. Painters(画家) can use it to draw beautiful pictures. If you like talking, you can talk to people from far away on the computer. You can watch movies and listen to music. Many children like playing games. Computers can help you.

In the shop, someone buys something from you. You can put the information about the sale. Then the computer can work on the information and tell you a report about shopping. In research (在研究领域), if you want to know about the moon, you can ask the computer and the computer can answer on the screen. In some large factories, you can’t see many people. Why not? Robots can do most of work instead of (代替) people. How does the robot work? The computer tells it what to do. This is our computer. Perhaps one day the computer can think and feel. Then it will make our life better and better.
