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 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,

　　xxx.

　　尊敬/親愛的xxx;

　　我今天給您寫信是要請(qǐng)5天的假，因?yàn)槲易蛱焱砩喜恍⌒母忻傲�。今天早上，我媽媽帶我去看了大夫，大夫告訴我要在家里躺幾天。所以，我對(duì)缺顆，特別是不能上您那有趣的顆，感到難過(guò)。我病好后一定把漏掉的課程補(bǔ)上。

　　此致

　             敬禮。

　　您的學(xué)生;xxx.
