敬爱的马老师：
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学了。昨天夜里我妈妈发高烧，咳嗽得厉害，我想她可能是得了流感。昨天晚上她休息得不好，而且今天很虚弱，所以我陪妈妈去天坛医院，然后在家照顾她。因此我不得不请假。如果您能准假我会非常感激。
Yours,
Li Li
