范文：
你是Jack 的朋友Jim 给你写信诉说他的烦恼：他喜欢上网有时上网到深夜。

他的父母认为这会影响他的学习和身体健康，不允许他再上网，因些他和父母争吵，并持续几天不和父母说话。

他很苦恼，向你寻求建议，90 词左右。

Dear Jim,
I'm sorry to hear that you have some problems with your parents. It's normal for teenagers to have such problems. You said you argued with your parents about playing computer late in the night. I really don't agree with you and I think your parents are right.
In my opinion, studying is the most important thing for us and playing computer will take up our free time. Firstly, I think you should say sorry to your parents, because what they did is good for you. Secondly, why don't you sit down and talk to them? Let them know you will work hard. Finally, you can do some other things in your free time instead of playing computer, such as reading books.
All in all, I think you were wrong, your parents care for you and you should understand them. I hope things will be better for you soon.
Yours truely, Jack.。
