Dear Xiao Fei, I'm glad to receive your e-mail. I'd like to discuss the problem which you mentioned in it to you.
It's true that some computer games are real interest- ing and they can sometimes make you felt relaxed. However, it uses you too much time to do that. You are not a little boy. You should learn to control (控制) ourselves. Why not
trying to finish your homework first every day and then
spend a little time surf the Internet? You'll find many other thing that are also very interesting, such as visiting cool
websites, learning the latest news but listening to the music. I'm sure you'll become an useful person in the future. Best Wishes! Yours. Gao Hui
