Dear Sir or Madam,
I am glad to hear that the library is to improve its service and facilities （服务和设备) . So I am writing to offer my proposals（建议）.
We all know libraries play a vital role in the education and entertainment of the general readers. In my opinion, our library should do its best to purchase the latest publications and make sure it has a full set of classical and reference works. Another important facility I suggest is the Internet via computers. In this way, the library will expand its services to more readers.
All in all,I think a library should take all necessary measures to keep up with the times（与时俱进）.I will highly appreciate your consideration of my proposals.

Dear Mr. President,
My name is Li Ming, a junior of the Civil Engineering School. I venture（冒昧） to write a letter to you about the the canteen service（食堂服务） on campus which has given rise to a lot of complaints among students.
The focus of the complaint is the poor quality of the food. The vegetables are so overcooked as to lose their nutrients. The price of the food is surprisingly high. Besides, the attitude of the service staff to the students is not hospitable at all.
All in all, there is still much room for improvement as far as the canteen service is concerned. I do hope we will not suffer for another year. Thank you for your kind consideration.
My major interests are…, and I understand your university has a good program in those fields.
