Dear Mr/Ms ;
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,
.
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，
