3、转换语言风格和思维角度，增加推荐可信度。自己给自己写推荐信不仅仅是摆事实的问题，还有一个口吻，行文问题。首先是内容上，除了补充自己自述中所没有的方面外，对于一些重要的成就和优点进行论述时，要从推荐人的角度考虑，切勿简单重复自述信或简历中的内容；其次是语言风格上，用词上要注意变换，不要出现你自述信中常用的习语等，最后在推荐信用的纸张、信封、字体、字号、段落等方面尽量避免雷同。
4、绝对避免语法、拼写或明显的用词错误。
下面是一篇较好的推荐信，请大家体会一下这些原则的运用。
In capacity as Professor of Mathematics at Fudan UniversityI＇m writing to recommend Mr. WangGesintosyour PhD program in Computer Science. I have known Mr. Wang since his sophomore year of collegeand have acted as his thesis advisor and mentor. In my experiencehe is a gifted and diligent studentand an admirably hard worker.
Wang is an impressive student because he has been forced to overcome the significant challenge of a serious illness during his freshman year. When I first met Wang in my Discrete Math classhe did not appear to be anything special to me. While his exam scores were goodthey were not as high as I would now expect of him. What I didn＇t know then was that due to his illnessWang was attempting to take all of the difficult early mathematics courses at one timeincluding Discrete MathematicsAdvanced MathematicsLinear Algebraand Possibilities. While most students found preparing for just one set of these exams difficultWang was overwhelmed by four of them. But in the endhe achieved an impressive score on the final examwhich made me conscious of his unusual determination he demonstrates when confronting difficult challenges.
