Dear Colleagues：
As a teacher in Department of Biology, Nankai University, a leading university in China, I am very pleased to take this opportunity to recommend one of my favorite students to your PhD program.
In September, 2004, Miss Zhang was my students in General Biology, the first professional course they take in the field. She likes it very much. I teach her in an open and interactive manner, she is active and passionate about answering class questions. Miss Zhang is bright, energetic and enthusiastic girl who loves speaking out her own ideas. She never escapes from those points of which she is skeptical. Apart from that, she often puts forward her ideas upon questions and exchanges all of her innovate ideas with me after class.
Upon ending of General Biology course, I asked my students to write an essay upon their understanding of biology. I discovered Miss Zhang’s essay was so impressive and persuasive; her careful essay comes from dozens of references to Biology literatures. In essay Miss Zhang stretched out her creative thinking upon status quo of biological research and branches in the field of biology. All of this speaks to her creative and logical and scientific thinking capability. I am gladly to say that Miss Zhang has a clear understanding about General Biology, that comprehension has been reflected fully in her essay. Therefore Miss Zhang got a full point for her essay in her class, and other students took it as model essay for granted.
I believe Miss Zhang’s industriousness, passion and dedication will make her an ideal candidate you are seeking for your program, so I highly recommend her without any hesitation to you. And I will greatly appreciate it if you could accept her into your program.
Sincerely yours,
Prof. ×××
推荐信是了解申请人的重要依据，在研究生课程中尤其如此。申请人可以选择现在或以前的老师、教授或雇主。推荐人必须熟悉学生的学习情况，了解学生的`学习目的是否明确，在学术上是否有前途，以及学生的适应能力、创造能力、品行和特长。
书写推荐信的最理想的人选是一封由系主任写，一封由专业课教授写，一封由自己的导师写。不过，对方若无规定，则除了自己的亲属之外，任何人皆可为推荐人。推荐人一般应具备高级技术职称，如教授、副教授、研究员、副研究员等。如果推荐人在国内外学术界享有盛誉，或者被申请就读学校聘为客座教授，或者曾经在该校讲过学，那么这样的推荐人写的推荐信就具有很强的效力了。
