dear mr/ms xxx;

today im writing to you to ask for a five-day leave, for ive 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. ill be sure to make up for the missed lessons after i recover from the illness.

yours ever,

xxx.

尊敬/亲爱的xxx;

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;xxx.
