一、格式
开头写称呼,后面用逗号：Dear (Peter),
正文
首先对自己不能按时会面给予道歉：I am (sorry) not to be able to (meet each other at 7:00 on time).
接下来提出自己的约请见面时间与地点并征求对方意见：I think we can arrange our appointment at some other time.How about (at 8:00).It is no fat for both of us to get the (cinema) handily as a pocket in a shirt; do you think it (Ok) to meet (outside) it?
下面做出自己的保证：I am (sure) not to fail to keep the appointment.
最后落款：Your xx,this very day.
【注：括号中为草稿要点】
二、全文如下：
