出国留学推荐信信封的格式
1)写信人的姓名、地址写在信封正面的左上角。
2)收信人的姓名、地址写在信封正面中心稍偏右的地方。
3)邮票贴在信封的右上角。
4)地址的写法是先写收信人或寄信人的姓名，然后按照从小到大顺序依次写出门牌号、街道、城市、省或州名、邮编，最后写国名。
5)收信人名前应根据需要加：mr(先生)、mrs(太太、夫人)、miss(小姐)、ms(女士，已婚或未婚均可)、dr(博士)、prof(教授)等留学生网留学点评，以示礼貌。有些中国学生给老师写信常用teacher作为称呼，这种用法不正确。在英语中teacher就跟worker，driver，farmer等一样是一种职业，不能作为称呼。男老师我们可以用mr，女老师我们用mrs、miss或ms作为称呼。

2)把收信人的姓名、地址(简称内地址)写在寄信人地址和日期的左下方，即信纸的`左边，低寄信人日期一至二行处。私人信件此项内容可以不写。
3)把称呼写在收信人姓名、地址下面，相距一行处。称呼一般以dear…开头，后面用逗号。如无地址，可以把称呼向上顺移。
4)书信正文从称呼下一行的3至5个字母开始。
5)如同汉语信一样，英文信的结尾也常写有祝好、盼来信、代向……问好之类的话，我们称之为结束语。
6)在信的结尾下面签上自己的姓名。除了对熟人或亲密的人以外，签名必须写全姓名，而且不管什么信件，都应由写信人亲笔签名。

【范文】
As Principal of George Mason High School I am delighted to recommend to you a stellar member of our teaching staff, Mr. Samuel Cohen, and to write this letter on his behalf. Sam has taught American History at the school for three years. He is one of our most popular and effective instructors and has already won several teaching awards.
He came to us directly upon completion of his bachelor’s degree, but immediately settled in as if an old pro. Sam is a master of all of the ingredients of successful teaching, especially the ability to inspire.
This gentleman is highly professional in both dress and demeanor. To my knowledge Sam has never come to work without both a suit and tie, more times than not a bow tie. The majority of others at the school, both teachers and students, dress differently and lean to more informality. Never once, however, has Sam’s manner of dress elicited the slightest comment. Why? It is simply because Sam’s attire seems entirely natural given his dignified comportment.
That comportment in turn is driven by Sam’s love and respect for American History. Sam views himself as the messenger for something serious and important, and this is reflected in the way he teaches and in the way his students respond.
Reaction to Sam’s classes has been overwhelmingly positive. So much so that more than once it has been reported to me that study hall students have been spotted lingering outside the door to Sam’s classroom listening to his lessons.
Sam’s impact has even been felt outside the school with the parents themselves. His section on the importance of voting has inspired students to cajole their parents to register to vote. Several have mentioned this to me at parent-teacher meetings. One even called the school to have me pass on their thanks to Mr. Cohen.
The only thing that we in the school administration have ever worried about in regard to Sam is the prospect of funding his bottled water. Sam is such a passionate and prolific speaker that he needs a steady supply to maintain his voice. So far we have gotten a pass on this, as students have bought it for him, including what must have been a year’s supply on his last birthday.
It will be a sad day when we announce that Sam will be pursuing his graduate degree on a fulltime basis. We can only hope that he keeps his promise and returns to us as soon as the ink is dry on his new diploma.
Sincerely,
Harold W. Brown
Principal
George Mason High School
