Dear Bob,
Im 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 wouldnt 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,
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,
xin
