Computers are very important for the students now. For the city students, it's very easy to surf (冲浪) the Internet. And for the village students, they can go to Internet bars. Most of them spend more than two hours there, and some of them even spend more than eight hours there. They can do their homework, download(下载) some information for their homework, download music, send email and play games. Most of them spend too much time playing games, so it's bad for their study.
