Dear Li Xiaojun,

Dear Li Xiaojun,
I'm glad to receive your letter.I'd like to discuss a problem with you.It is true that some video games is good for your thinking ability and they can sometimes make you flet relaxed.Therefore,you are spending too much time on that.You're not little boy any more.You should ___m(因为印刷问题，这个单词没打上) to control yourself.Why not to try to finish your homework first every day and then spend a little time play some video games?I think,like a student,the most important time is to study hard at school.You should try your best to get good grade in your subjects and try to become a useful person at the future.
