这个人是一定很熟悉你在课堂上的表现的人，你可以去找你成绩比较好的那门课程的老师，这个老师不一定是比较出名的老师，但是一定是非常的了解你学术能力的老师。
如果给你写推荐信的人和你并不熟，甚至是这个老师不认识你，那么这个老师写出来的推荐信是虚假的，不能让人信服。只有对你非常熟悉的老师写出来的推荐信才是真实可信的。
。你可以把你写好的个人简历拿给老师看看，一起找出写作的好素材。
二、内容
推荐信里面要先介绍推荐人和学生的关系，内容上主要是写对学生的能力方面的推荐，要通过几个具体的例子来描述学生的优势，比如在描写到学生的能力的时候，就可以把学生的成绩、获得过的奖励和参加过的学术会议给讲述出来。
如果是说工作方面的事情的话，可以说一下学生的领导能力和团队写作能力等等，学生对待学习和工作的态度是推荐人要进行评价的。最后还要说明是支持学生到这个学校学习此专业的，并且对学生是充满信心的，能够对学生能够进入到这个学校而感到自豪。
三、注意事项
递交推荐信是有截止的时间的，要提醒推荐人截止的时间是在哪一天，推荐信的内容最好是控制在一张A4纸，如果内容写得太多了的话，招生的老师也是没有耐心都把它看完的。
还有要写得客观一些，对学生太过于肯定的话是不会让招生的老师相信事实就是如此的，可以在推荐信中说一下学生还有哪些要改进的地方。

Dear Prof. Dr. 0000
I take great pleasure in writing this letter of recommendation for Dr. 0000 to support his application for a postdoctoral position in your lab. Dr. 000 is an outstanding graduate student working for the M.S. degree under my supervision. In my contact with him in the University， his creativity and attitude to research work gave me deep impression. He always proposed new ideas on his research and could
resolve problems by himself， I was very satisfied with him. Dr 000 has been working on molecular luminescence research about six years. As I know， most of his researches have been concentrated on bioanalytical chemistry in his Masters work， such as protein and nucleic acids assays etc. In these fields， Dr. 000 has strong background and research ability. He has and would be published several papers in international journals. I am often interested in reading his papers in publication and discussing with him. I am very appreciated of his research ability. Dr 0000 also possesses very fine character. He is a devoted research worker. He works on weekends. He is an honest and smart， reliable and responsible person， and is very cooperative too. Based on these qualities， I believe this young man will achieve greater academic success in his future work. Therefore， I strongly support his application， and it would be greatly appreciated if you could give him your favorable consideration.
Please feel free to contact me if I can answer any additional questions about 00000. My address is as follows：
