Most people have computers at home. Some of them are big, but some of them are very small. Computers are very useful. People like playing on the computer. They have a lot of functions(功能), so people can do a lot of things by computer. There are two computers in my home. One is in the study and the other is my parents' bedroom. Every day, I use the computer to do my homework or play games. My father likes watching news and my mother does online shopping a lot. It can make our lives very colorful and convenient(便利的). Many people can make good use of computer, but some young people can't use computersproperly. They play games on it, too much. It's bad for their eyes. Computers are our good friends. All of us should use them in a right way.
