Dear professor Jackson:
I am indeed very sorry that I missed the examination you gave on Moby-Dick last Wednesday. I feel badly about it and want you to know what happened.
On my way to class that day,I had a flat tire,and I had to go with the mechanic when he repaired it. It took me more than one hour to get it done. A copy of the bill is enclosed.
I sincerely hope you can accept my apologies and understand my situation. I would appreciate your allowing me to take a make up examination. I will come to your office during your office hour on Monday to discuss this possibility with you. Once again,Im sorry fro any inconvenience caused.
Sincerely yours.

指发信人的姓名（单位名称）、地址和日期，一般写在信纸的右上角。一般公函或商业信函的信纸上都印有单位或公司的名称、地址、电话号码等，因此就只需在信头下面的右边写上写信日期就可以了。
英文地址的写法与中文完全不同，地址的名称按从小到大的顺序：第一行写门牌号码和街名；第二行写县、市、盛州、邮编、国名；然后再写日期。标点符号一般在每一行的末尾都不用，但在每一行的之间，该用的还要用，例如在写日期的时候。
日期的写法，如1997年7月30日，英文为：july 30，1997（最为普遍）；july 30th，1997；30th july，1997等。1997不可写成97。

See you then. Yours， XXX ( 落款写在右下角，标点是逗号
