Dear Ms Ma,
I am sorry to tell you that I can't go to school today. Last night my mother had a high fever and a bad cough. Perhaps she has caught flu. I will take my mother to Tiantan Hospital and then look after her at home, so I couldn't go to school today. So I would like to ask for one day's leave. I will be very grateful if you grant my leave.
Yours,
Li Li
敬爱的马老师：
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,她可能得了流感.因为今天我要带妈妈去天坛医院,然后在家照顾她,所以不能去上学了.因此我想跟您请一天假.如果您能准假我会非常感激.

Dear Ms Ma,
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.
Yours,
Li Li
