Dear Mrs. Miller，
I’m writing to introduce to you Mr. Wang，one of my high school classmates in Beijing. He is presently working for Lenovo Technologies and is going to be transferred to its branch in your city next month.
Since this will be the first time for him to work in a foreign country，he will possibly be faced with many problems，and especially the housing problem.
He hopes to obtain your guidance and help in finding a good apartment to live. You’ve been living there for more than 10 years，so you are surely familiar with things there.
If you can kindly help find rental quarters for her，I’ll be very ks for your due attention to this letter and hope to receive your reply soon.
Many thanks to the trouble you will have to take for Mr. Johnson.
To Whom It May Concern，
I have had the distinct pleasure of having Kaya Stone as a student in my debate classes and on my debate team for three years at Eastern Little Hope High School.
Kaya has been more than the ideal student. In order to achieve the highest grades and my deepest respect，she has demonstrated outstanding leadership and maintained a clear sense of purpose.
The academics at Eastern Little Hope are most challenging，and Kaya fulfilled all the requirements with the added challenge of honors and advanced courses. Kaya is an outstanding extemporaneous speaker and debater. She has won many awards on the speech and debate circuits，and qualified for national tournaments.
Success in these interscholastic activities requires extensive research and persuasive skills. Kaya also holds the degree of Special Distinction，as a member of the National Forensic League.
Due to its nature of metro，state，and national interscholastic competition，the successful high school forensics student serves by not only representing his or her school but also by representing his or her community as well. One of the requirements in my advanced class is to prepare lectures and guidance for the beginners.
With Kaya’ s superior knowledge and involvement in the political sciences，she developed a strong sense of confidence with a charming attitude. Therefore，I could always depend on her to set the best example as an instructor. Because of her natural leadership abilities，Kaya was selected as our Debate Captain. On account of her mature approach to her responsibilities，I often thought of Kaya as a colleague.
Since her classmates，my fellow teachers，and I will always hold her in the highest esteem，I sincerely recommend Kaya Stone as the ideal candidate for matriculation at Eastern Little Hope State.
we are pleased to introduce mr. wang，our import manager of textiles department. mr. wang is spending three weeks in your city to develop our business with chief manufactures and to make purchases of decorative fabrics for the coming season.
we shall be most grateful if you will introduce him to reliable manufacturers and give him any help or advice he may need.
It is my pleasure to recommend Mr. xx for his application to graduate studies in your school. Mr. Wang has been my research assistant of the National Science Council＇s 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.
