亲爱的同事们， 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. 在通识生物学课程结束时，我要求学生写一篇关于他们对生物学的理解的文章。我发现张老师的文章是如此的令人印象深刻和有说服力；她那篇细致的文章引用了几十篇生物学文献。在论文中，张小姐对生物学研究的现状和生物学领域的分支进行了创造性的思考。这些都说明了她的创造性、逻辑性和科学思维能力。我很高兴地说，张小姐对普通生物学有一个清晰的理解，这种理解在她的文章中得到了充分的体现。因此，张老师的论文在班上得到了满分，其他同学也理所当然地把它当成了范文。 我相信张小姐的勤奋、热情和奉献精神会使她成为你们项目的理想人选，所以我毫不犹豫地向你们推荐她。如果您能接受她进入您的项目，我将不胜感激。 Sincerely yours, 教授
