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/亲爱的;
我今天给您写信是要请5天的假，因为我昨天晚上不小心感冒了。今天早上，我妈妈带我去看了大夫，大夫告诉我要在家里躺几天。所以，我对缺颗，特别是不能上您那有趣的颗，感到难过。我病好后一定把漏掉的课程补上。
此致
敬礼。
您的学生：.
