假如你是李华，你的笔友Jim最近沉溺于玩电脑游戏，为此你很担心。请根据下表提示给Jim写一封信，谈谈你的看法及建议。佳作欣赏
Dear Jim，
I really feel worried about you.You used to do well in your lessons and took an active part in the activities at school，but now you take no interest in your schoolwork and don’t listen to teachers as carefully as before in class.Also，you are so crazy about computer games that you can’t hand in your homework on time.Perhaps playing computer games can make you feel relaxed，but if you spend too much time on it，you will have less time to study.And it may do harm to your health.I hope you should achieve a balance between your schoolwork and your hobbies.Why not join in some outdoor activities when you feel bored？As your friend，I’ll be glad to share your happiness and sadness.
Yours，
Li Hua名师点睛
