推荐信一般来讲具有以下特点。
(一)荐举贤能
推荐信是向用人单位介绍、荐举自己或自己了解的优秀人才，能够使有才能的人可以为用人单位所用，为社会造福。一个没有才能的人既不可能有自荐的信心，同时也不会得到别人的信任而受到举荐。
(二)公私兼顾
推荐信无论是以单位名义发文，向有关单位推荐人才，或是以个人名义向组织推荐或向个人推荐人才，这其中均有举荐人才，公私兼顾的特点。从某个角度来说举荐信可以认为是一种私人之间的'通信。凡是写举荐信的人均希望自己的举荐可以成功，得到承认。

to whom it may concern，
it is my great pleasure to recommend miss lili zhang to you， as she was one of my finest students in our department。
miss zhang began attending my english classes in the department of international trade university in 1992 and graduated in spring of 1996。 though it has been over eight years since i last saw her， the deep impression she made on me has not faded in the least。 she is very intelligent， honest， creative， articulate， adaptive person。 her high academic achievement speaks for itself: she consistently scored in the top 5% in class。
i am certain that miss zhang would make great contributions to your company， and i strongly recommend her for the position。 please do not hesitate to inquire further if i can be of help to you。
sincerely，
tim wu
