根据3WU同学的comments，改进后的样子：<br />
<br />
Dear Mr. Jackson,<br />
<br />
I am writing to request an extention to the return date of the books I borrowed. It was about one month ago, I borrowed three books from the Library, so they are supposed to be returned by next Monday.<br />
<br />
Unpredictably, I have to stay in the hospital to take care of my brother, since he was injured in a serious accident yesterday morning. I rushed to the hospital and found his situation is not good. I am afraid I could not get back within at least two weeks. Besides, Martin, my roommate, also went out, and the time when he will be back is unsure at the moment. Otherwise, he would be able to help me return the books. For the above reasons, it is almost impossible for me to get them back in time.<br />
<br />
I am deeply sorry for the late return. However, I would appreciate it very much if you could allow me a two weeks' extenstion. I promise to return them as soon as I am back. Thank you very much for your understanding and kindness help. I am looking forward your reply.<br />
<br />
Yours Sincerely<br />
<br />

最后给点修改：
原文“I am really sorry for returning the books late. I promise to return them as soon as I am back. I will appreciate it very much if you could give me two more weeks' time to return them.
Your Sincerely
”
根据原文的修改：
Once again, I am deeply sorry for the late return. However, I would appreciate if you could allow us a loan extenstion for 2 weeks. I promise to return them as soon as I am back. Thank you very much for your understanding and kindness help. I am looking forward your reply.
Your(s) Sincerely，
* 1） 如果你之前已经道歉，建议使用 （Once again）
2） 注意逗号 after yours
3) 文章开头 写 I am writing to request a loan extension on two books I borrowed from you xxx ago.
