　　According to a recent investigation, about 30% of the city families have computers. Besides, many village people are more and more interested in computers and some of them even have bought computers. About 70% of the parents bought computers for their children to study, and some for their work. And even some people bought them for entertainment. The fact how the middle school students use the computers really surprises us. Only about 30% of them use computers to find out useful information. About 60% of them use computers to chat with other people on the Internet. What is worse, about 60% use computers to play games and 20% use computers to watch VCDs or listen to music. In my opinion, we should make better use of our best invention-computers.
