感谢信：
Dear Mr. and Mrs. Smith,
I am now back to China safe and sound. In this letter I would like to convey my heartfelt thanks to you and your lovely children for your kindness and hospitality to host me when I was in New York.

申请信：
Dear Sir or Madam,
I am writing to express my great interest in the "Olympic Volunteer Recruitment"launched recently by the Beijing Olympic Committee, and I would like to apply as a qualified candidate.
As I am an English major, my fluency in both Mandarin and English, as well as my basic command of French, guarantees that I meet the language requirement for the various volunteer positions. More importantly, I have been an enthusiastic participant in many international exchange programs-which are reflected in my attached resume-and therefore, I believe my communication skills make me competent for such a post.
Should you grant me an interview, I would be most grateful.
Yours truly
Li Ming

投诉信：
Dear Manager,
I venture to write to complain about the quality of the digital camera I bought last Friday at your store. During the five days the camera has been in my possession, problems have emerged one after another. For one thing, the screen is always black,making the camera no different from a traditional one. For another, the battery isdistressing as it supports the camera's operation for only two hours. Therefore, I wish to exchange it for another camera or declare a refund. I will appreciate it if my problem receives due attention.
Yours,
Li Ming

译文：
尊敬的经理：
我冒昧给你写这封信，投诉我上周五在您商店里购买的数码相机的质量问题。购买至今的五天中，各种问题一个接一个地出现。一方面，相继屏幕总是黑屏，我们使用起来仿佛和传统相机没有区别。另一方面，电池的状况也不尽人意，只能支持相机工作两个小时。因此，我希望可以换一个相机，否则我要求退款。我希望这个问题能够得到足够的重视。
谨上，
李明
