To Department Office

Secretary Li，

I'm sorry to apply for a ten-day leave from the Aug.23rd to Sept.3rd instant.My father now in the hospital is badly ill.I have to go to see him and take care of him for a few days.You know I'm the only child in my family.Of course I will show you the telegram about my father's illness which is received from my mother to support my application.

As for the missed lessons during my absence，I promise I will do my best to catch them on after I come back to the campus.Wish for your allowance.

【解析】本文是一封请假条，一般我们要向上级或老师请假，通常用的是ask for leave这个短语，请三天假可写作：ask for a three-day leave；因病请假则是ask for sick leave。leave在这里是名词用法，文中用的短语是apply for意为“申请”，含有更加郑重的意味，常用于下级对上级或晚辈对长辈的书面语中，only child意为“独生子女”，相应的，“独生女”译作“only daughter”而“独生子”译作“only son”。
