Dear Mr.Wang
This is WangHua.Remenber me?How are you now?I need your help because I am not very used to the high middle school life.
We have nine subjects at all.Every day I have to spend at least three or four hours doing my homework,so there is little time for activities after class.I hardly have any time to do what I want to.Besides ,I sometimes feel sleepy in class because i do not have enough sleep.The great pressure of exams and the high expectations from my parents often make me even more tired.
The higgest problem i meet now is my maths study,which is much more difficult than that in junior middle school.I do not know how to improve it.So I hope I could get some advice from you.
All the best.
Yours,
Li Hua
