Dear Mr. Zhang
I’m writing to ask for your help.
The next united examination is coming, but I feel more and more nervous and these days I can’t fall asleep as usual. What should I do?
Yours,
Li Hua
Dear Li Hua
I’m sorry to hear that you have difficulty in falling asleep for a long time.
Yours,
Mr. Zhang
Dear Li Hua
I’m sorry to hear that you have difficulty in falling asleep for a long time.
From your letter I know that it is stress that causes your problem. So I suggest you do as follows. First of all, you must adjust your attitude towards exams and believe in yourself. As long as you are confident, you can do your best in the exams.
Besides, you should have enough sleep every day. Meanwhile, don’t forget to take part in some activities to relax. With a healthy body, I’m sure you will study more efficiently.
Last but not least, you’d better make a reasonable study plan and stick to it. In this way, you will have a sense of achievement and then avoid being stressed out all the time.
I hope the suggestions will be of some help. Good luck!
Yours,
Mr. Zhang
