Suppose you are a student and are ill so you cannot attend the class today. Write a sick leave to your teacher.
● 参考范文：
Dear Prof. Kang,
I am very sorry to tell you that I cannot attend today's lecture held by you owing to the fact that I caught a bad cold last night. The doctor said that I should stay in bed for a couple of days. Thus I am compelled to ask for sick leave of two days. I shall make up for the missing classes by consulting my classmates and return to class as soon as I feel better.
Enclosed with this letter is the doctor's certificate.
Yours respectfully
Li Ming |
