参考范文

Dear Wang Peng，

　　I am sorry to hear that you have been ill for days and hope you have got better now.You have been so absorbed in study that you have had no time for exercise.But it is really harmful to your health.I feel it would be more beneficial to your health if you could take more exercise in future.

　　In fact，exercise can contribute to your health and fresh your mind.Only when you have a strong body can you keep on studying without feeling bad or ill.Otherwise，your study will be interrupted from time to time by sickness.

　　In a word，exercise is as useful and important as your study.So I put forward a suggestion that you take at least one hour's exercise every day from now on.

　　Best wishes.

Yours，
