Dear  Prof.Smith,
      It has always been a great pleasure to write to you since I can never fail to get help,inspiration or enlightenment from you. Now I am writing to recommend to you Miss Liu Ming who wants to pursue her graduate study for the Master's Degree under your supervision.
      Miss Liu Ming was one of my classmates in Tianjin university, she was one of the most excellent students in our university as can be seen from her straight A grades on all subjects.After graduation she worked in Tianyi Biological Company for three years,which considerably added to her practical experience.
      It is my belief that with her intelligence,diligence and rich experience,Miss Liu Ming has great potential for further development in the field of pharmacology both theoretically and practically.Therefore,I recommend her to you with no reservations.
                                                                                      Faithfully yours,
                                                                                                     Li Ming
