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.
尊敬的先生/女士;
今天我向您请一天假，因为我昨天晚上不小心感冒。
今天早上，我妈妈带我去看医生，医生告诉我要在床上呆几天。所以我很抱歉没有从学校，特别是你有趣的课。我从病中康复后，一定会弥补错过的课。
你永远的朋友，
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.

亲爱的高小姐，
对不起，我今天不能去上学了。昨天我帮助农民们在农场里和我的同学们一起摘苹果。不幸运的是，我从梯子上摔下来伤了腿，但我并不严重的伤害。医生让我躺在床上好好休息。所以我要求离开两天。

Dear Mr. Smith，
I am really sorry to tell you that I cannot attend the training course next Tuesday， because ny manager has appointed me to go on a 3-day business trip to Hainan. Will you please record the lecture for me to review later?
Thank you for your consideration.
Yours faithfully，
Li Ming
