英语作文关于通知的格式以及句式【一】
位置在下面称呼语隔一行，是信的核心部分。因此要求正文层次分明、简单易懂。和中文信不同的是，正文中一般不用hello！（你好！）
正文有缩进式和齐头式两种。每段书信第一行的第一个字母稍微向右缩进些，通常以五个字母为宜，每段第二行从左面顶格写起，这就是缩进式。
但美国人写信各段落往往不用缩进式，用齐头式，即每一行都从左面顶格写起。商务信件大都采用齐头式的写法。

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.
