英语作文正规书信格式【一】
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。

Dear John,
I am writing to thank you for looking after me after that unfortunate accident the other day, when I was knocked off my bike by a taxi. If it had not been for your assistance in giving me first aid and taking me to a nearby hospital, I fear that the consequences might have been much more serious.
The doctor says that my broken leg is healing well. In addition, the taxi company has agreed to pay my hospital bills. Everyone agrees that it was your quick-witted response in that Emergency that has led to this satisfactory outcome.
Although nowadays many people talk about the need to be unselfish and to help others, we see very few people practicing what they preach. But you showed by your actions that you are an exception.
Yours sincerely.
