要想写好一封求职信，首先要把信的结构搞清楚。由于对招聘的`具体人员不了解，求职信的开头一般是"Dear Sir or Madam"，这样的称呼既包含了对招聘方的尊敬，又不至于搞错性别。在求职信的结尾，通常以"Yours，Liming"这样的落款来结束全文。
Dear Sir or Madam:
With reference to your letter on Dec.23rd,i'd like to ,first of all,convey my deepest appreciation to your offering me the position of manager assistant in your company.And i am more than delighted and honored to gain your trust and assignment.
However,i have to decline this unexpected offer whih all unwillingness, which mainly results from an abrupt change in my schedule. when i applied for the position a week ago , i aslo sent an application to cloumbia University, for i hadn't yet made up my nind whether to start work afger graduation this month . What a coincidence ! i got the adminttance to the graduate school of English literrature in Columbia University the same day i received your letter. Weighing the pros and cons for an entire night ,i determine to seize the changce for further study abroad.
With my earnest apology, i do hop you can pay me due understanding and forgiveness for turning down your offer. in closing ,may your company have great prospects and enjoy extensive popularity.
Dear Mr. President,
I am writing to express my concerns over the library service on the campus.
As a major in English, I find that most of the books in English in the library are outdated.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 1995. 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 air-conditioning 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.
