Dear Miss Zhang,
I am sorry that I can’t go to school tomorrow, because I got a bad cold the day before yesterday. This morning, I had high fever and I went to see the doctor. He told me to stay at home and have a good rest. Here is the certificate he gave me. I will go back to school as soon as I recover.
Sincerely yours,
Blair
尊敬的张老师：
我很抱歉我明天不能去学校了，因为我前天感冒了。今天早上我发高烧去看医生了。医生要我待在家好好休息。这是医生给我开具的证明。我一恢复就尽快回学校。
