Dear Miss Gao,
I'm sorry I can't go to school today. I helped the farmers pick apples with my classmates on the farm yesterday. Unluckily, I fell off the ladder and hurt my leg, but I wasn''''t badly hurt. The doctor asked me to stay in bed and have a good rest. So I ask for leave for two days.

Dear Miss Zhang,
I am sorry that I am unable to attend the morning classes because of a bad cold and high fever. Enclosed is a certificate from the doctor who said I must stay in bed today. I will go back to school as soon as I recover.
Yours respectfully,
