Dear Bob,
I am the Chinese student who stayed in your apartment during my vacation in Canada. Now I have returned home in China and the purpose of my writing this letter is to express my sincere apology for the stupid mistake I have made.
Upon arriving home, I found the music CD which belongs to you in my luggage. I am in great worry because I know this your birthday present from your wife. Your CD will be sent immediately through EMS in the very near future. I have been told it will take about a week to reach Canada .
Once again, please accept my sincere apology for any inconveniences I have caused. Thank you for your understanding and please send me a reply at your earliest convenience.
Sincerely yours,
Li Ming
Dear David:，
I am afraid that you will think me unpardonably negligent in not having answered your letter dated 7, December sooner, but when I have told you the reason, I trust you will be convinced that the neglect was excusable. When your letter arrived, I was just in Hong Kong. As my family could not forward it to me during my absence, it has been, therefore, lying on my desk until the moment when I took it up. Now the first thing I have to hasten to do is to write to you these few lines to express my deep regret.
yours，
Sara

道歉信是指因过失或疏忽做错了事，给别人带来了麻烦或损失，发觉后要立即写信给对方赔礼道歉时写的信件。道歉是一种礼貌，道歉信要写得坦率，诚恳。
道歉信通常包括三部分内容：1、表示歉意，道歉的原由;2、出现差错的原因，提出弥补措施;3、请求原谅。语言要诚挚，解释的理由要真实。好的道歉信不仅会取得对方的谅解，还会增进彼此的感情。
写作"三步曲"：
表示歉意→说明具体原因、提出补救办法→再次致歉，希望得到理解。注意：
理由要尽量合理，违反生活常识将导致扣分;尽量提供一个合适的补救办法，使行文更加顺畅。

Dear Dr. M.C.(note: name of the editor),
I am terribly sorry to write this letter to you for my apology.
When I know about this affair, I was not too much startled and shocked, because after the student sent the same article to two of your magazines, I had found it from my E-mail massage. Immediately I gave the student very serious criticizes.
Anyhow, on the following day, the “AFM”(Note: name of the journal), one of the two magazines, gave the feedback response, saying that this article is rejected for some reasons. Therefore, I took it for granted that there is no more problem of “one paper for two magazines”, and neglected apology. Now I do realize this serious matter and feel absolutely sorry about that.
As for this irrecoverable thing, I am to blame. I was so careless with my student’s action. This is a warning to me to be more careful in the future. Although the student’s distributing one article to two magazines is without my permission but only her own action, I do not want to escape from my responsibility as a teacher. In this regard, I am deeply disappointed and saddened. However, I wish this matter will teach my student a lesson.
Lastly, I would like now to apologize to you for all the troubles and problems that have happened. I promise that this kind of thing will never happen again. I hope I can have your forgiveness, and please give me chances to contact with you in the future.
Thank you for listening to what I have said.
Sincerely yours,
