One possible version:

Dear Dr. Helper,

I am a Senior 3 student. I am now in great need of your help because I can hardly stand the great pressure.

Every day I have to stay at school for nine hours to have lessons and spend at least three to four hours doing my homework at home. We teenagers are eager to play and enjoy ourselves, but we hardly have any time to do what we want. Besides, we even don’t have enough sleep.

There seems to be three causes about the overload: the pressure of examinations, too much homework and the high expectations from the parents. We are often warned that if we don’t do our best, we won’t have the chance to go to university. I write this letter only to wish that I could have someone to talk to. I am looking forward to your advice.

　　　　　　　　　　　　　　　　　　　　　　　　　　　 Yours sincerely,

　　　　　　　　　　　　　　　　　　　　　　　　　　　　 Li Hua
