敬愛的馬老師：

　　I apologize that I cannot go to school today. Last night my mother had a high fever and coughed badly. I think that she has got flu. She didn t have a good sleep and is very weak today, so I will go to Tiantan Hospital with my mother, and then stay at home to attend her. Because of this I have to ask for leave. I will appreciate you very much if you can allow my leave.

　　很抱歉我今天不能去上學了。昨天夜里我媽媽發高燒，咳嗽得厲害，我想她可能是得了流感。昨天晚上她休息得不好，而且今天很虛弱，所以我陪媽媽去天壇醫院，然后在家照顧她。因此我不得不請假。如果您能準假我會非常感激。

　　Yours,

　　Li Li
