　　in capacity as professor of mathematics at fudan university?i'm writing to recommend mr. wang?gesintosyour phd program in computer science. i have known mr. wang since his sophomore year of college?and have acted as his thesis advisormentor. in my experience?he is a gifteddiligent student?and 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 class?he did not appear to be anything special to me. while his exam scores were good?they were not as high as i would now expect of him. what i didn't know then was that due to his illness?wang was attempting to take all of the difficult early mathematics courses at one time?including discrete mathematics?advanced mathematics?linear algebra?and possibilities. while most students found preparing for just one set of these exams difficult?wang was overwhelmed by four of them. but in the end?he achieved an impressive score on the final exam?which made me conscious of his unusual determination he demonstrates when confronting difficult challenges.

　　mr. wangi have often talked about a variety of mathematicscomputer science conceptsproblems. during these discussions?i always found him to be delightfully intelligent. not only does he quickly understand the conceptsproblems presented to him?he is able to analyze these problemspresent solutions. but perhaps most important is that wang's thinking is intensely rigorous. when looking at any question?he carefully scrutinizes itif he finds any uncertain issue

　　he clears them up immediately. i believe this kind of thought is essential to become an excellent computer programmer.

　　serving as his thesis advisor?i had a first-hand opportunity to observe the way in which wang's mind works. in his senor thesis?mr. wang mainly discussed two challenging questions in regards to′ann′。 in our books in china?knowledge of annits uses are very rare. few people in china have studied this topicconsequently?the materials that are available on ann are limited. working on this difficult project?not only did mr. wang rise to the challenge?but he went abovebeyond the call of duty to analyze his secondary sourcestest them for accuracy in practice. in this way?he found mistakes in the book that we use. his diligencehard work made me extremely proud of him.
