美國留學推薦信開始就應該開門見山地介紹一下所推薦的這個人的能力和推薦人對他的熟悉達到什么程度，以及跟他的關系。如果被推薦的人是推薦人的學生，僅需要介紹他們關系，以及他給你的總體印象。

　　如果被推薦的人是你的下屬或合作者，你有必要先介紹一下被推薦人擔任的職務，他個人在任中出色完成的一些項目，接著簡要地談一下你對被推薦者的看法。如果沒有這些就顯得有點突兀，例如：

　　Mr. Wang is an enthusiastic and progressive young man with extremely high potentiality. He is not only quick at learning and good at solving difficult problems, but also with a logical mind that enables him to effectively analyze difficulties. All the work handed to him was completed satisfactorily. Actually, he is so reliable that I assign him with heavy responsibilities. With his help, I have been able to spend more time in writing the research paper. I really consider myself very fortunate to have such a capable assistant.

　　這是一個出國推薦信的開頭，沒有任何的關于推薦人和被推薦人關系的介紹，上來就是介紹被推薦人一堆優點，一方面讓人覺得太唐突，另一方面，讓人對這封推薦信的可信度有所懷疑。
