英文介紹信三Dear Sir:
It is my pleasure to recommend Mr. Fuping Wang for his application to graduate studies in your school. Mr. Wang has been my research assistant of the National Science Councils project- The United States and the United Nations Financial Crisis: The Role of U.S. Congress since September 1997.
His major responsibilities include information collecting, analyzing and translating. He is an enthusiastic and progressive young man with extremely high potentiality. Mr. Wang is not only quick at learning and good at solving difficult problems, but also with a logical mind that enables him to effectively analyze difficulties. All the work handed to him was completed satisfactorily. Actually, he is so reliable that I assign him with heavy responsibilities.
With his help, I have been able to spend more time in writing the research paper. I really consider myself very fortunate to have such a capable assistant. I am certain his diligence, coupled with a good competence and pleasant personality, will assure him of academic achievements in his future academic pursuits. I strongly recommend his admission without any reservation.
Sincerely yoursxxx
Dear Mr. Johnson,
I take great pleasure in introducing Mary Brown one of my classmates and best friends to you. She is going to pursue her education as a postgraduate in your university after her graduation here. She and I had lived and studied together for four years. No friend deserves so much love and respect as she does. Now that we have finished our study here we had to part with each other.
Will you please give her some guidance in regard to the entrance examination? Any information you can provide, as well as your introduction for him to meet the future tutor shall be appreciated very much.
Yours truly,
Emma
