Dear Mr/Ms：
Today I'm writing to you to ask for a five-day leave, for I've got cold last night with carlessness. 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，
