Dear Arthur,
In your last letter, you told me something about your sister’s surfing on the Internet. I’m familiar to your situation. As computers become more and more popular, some students cannot help play online games and chatting. It is not only a problem of wasting time, and a serious problem for their future! What you should do at first is to find out what make her addicted to computer games. Lack of love from parent? Poor scores? Then having a heart-to-heart talk with her. Secondly, you should help herself with her study to build up her confidence and make her interesting in it. Thirdly, find something else for her to do instead computer games. Your efforts will surely help change her life.
Yours,
Colin
