Dear,
I am terrible sorry for not having attended your class on time. Because I had got a headache for several days and it is my first time to live in Chongqing and I can not suit for the weather here quickly.
To be honestly, I like learning English very well and I have made my mind to learn it well both on spoken English and on written English. I think you will be my best teacher to help me improving my English Level. So I apologize again for my not attend your class. I will make my great effort on English in the future and will not make you disappointment next time!
Excuse me for my unintentional fault!
Sincerely yours,
Tom
Dear professor Jackson：
I am indeed very sorry that I missed the examination you gave on Moby-Dick last Wednesday. I feel badly about it and want you to know what happened.
On my way to class that day，I had a flat tire，and I had to go with the mechanic when he repaired it. It took me more than one hour to get it done. A copy of the bill is enclosed.
I sincerely hope you can accept my apologies and understand my situation. I would appreciate your allowing me to take a make up examination. I will #e to your office during your office hour on Monday to discuss this possibility with you. Once again，I''m sorry fro any inconvenience caused.
Sincerely yours，
Alice
Dear Bob,
I'm writing to apologize for having forgotten to return the "the Beatles" CD to you when I left Canada,I was in such a hurry that I packed everything in my luggage without checking carefully.Had I paid more attention then,I wouldn't have made such a stupid mistake.
Now something must be done to solve the problem because I understand you cherish the CD enormously.I can either send it to you by express mail or alternatively compensate you at a reasonable price.If you do not mind,I may bring it back to you next time I go to Canada.
Please let me know which solution you prefer at your earliest convenience.I really hope you will accept my sincere apology.
Faithfully yours,
Li ming

Dear kate:
Excuse me for my long delaying in returning to you your “robinson crusoe” which i read through with great interest. I had finished reading the book and was about to return it when my cousin came to see me. Never having seen the book, she was so interested in it that i had to retain it longer. However, i hope that in view of the additional delight thus afforded by your book, you will overlook my negligence in not returning it sooner.
Thanking you again for the loan.
yours，
Tom

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
