【参考范文】
Many students like getting online very much. They can learn how to use the modern machine — computers. They can learn much more knowledge from the Internet. It can make them clever by playing different kinds of games.
But some students spend too much time playing games. Some even make friends online. It takes them too much time to write too many letters to each other, so they do worse in their lessons.
I think they mustn’t get online when they’re studying at school. They can do it in summer or winter holidays.
