假设你是刘虹，请你就本校图书馆的状况给校长写一封120词左右的英文信，内容应涉及图书馆的藏书数量和更新状况、环境、服务等。
Dear Mr. President,
I am writing to express my concern over the library service on the campus. As a major in English, l find that most of the books in English in the library are outdated. So far, I have not come across a single book published after 2010. As a result,we fail to get the latest information of academic development both at home and abroad. In addition,the light in the reading room is far from bright which does harm to our eyes. Worse still, there is no airconditioning and we are sweating heavily while reading. Last but not least, the newly developed electronic information system does not work well and needs further improvement. A great number of books should have been listed in the system. There is no denying that the library has helped us a lot. But it is in urgent need of improvement. When improved, the library is certain to provide much more help with our study. Thank you for your time. I am looking forward to your reply.
Yours sincerely,
Liu Hong
