　　Dear Mr/Ms XXX;

　　Today I'm writing to you to ask for a five-day leave, for I've got cold last night with carelessness.

　　This morning my mother took me to see the doctor, who told me to stay in bed for some days. So I am very sorry to be absent from school, especially your interesting lessons. I'll be sure to make up for the missed lessons after I recover from the illness.

　　Yours ever,

　　XXX.

　　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.
