Dear Ms Ma,

敬爱的马老师:

I apologize that I cannot go to school today.

很抱歉我今天不能去上学了。

Last night my mother had a high fever and coughed badly. I think that she has got flu.

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。

She didnt 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.

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。

Because of this I have to ask for leave.

因此我不得不请假。

I will appreciate you very much if you can allow my leave.

如果您能准假我会非常感激。

Yours, Li Li

您的学生 李丽
