【正确答案】Dear Sir,
I am writing in response to the advertisement you placed in the Sunday paper for a part-time research assistant. Next year I will receive a bachelor's degree in chemistry, and this job would give me the experience I will need for my future career in this field. I believe that both my education and experience are directly related to your needs.
As an undergraduate,I have taken many courses in chemistry and developed a great deal of practical experience. As a result, I can, at this point, perform most laboratory procedures with little or no difficulty. Because my primary interest is in polymer chemistry, I feel certain that I could carry out any assignments you would give me. Besides taking courses in chemistry, I have taken many optional courses such as computer programming, electronics circuit design and surface science. In addition, I spent last summer helping Professor Liu in surface chemistry.
I would appreciate the opportunity to join your staff because your company enjoys a reputation for helping students like me to gain experience in industry. I enclose a resume and could be available for an interview at your convenience.
Sincerely,
Zhang Xi
