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 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。
I enjoyed many pleasant sights during my trip。
I shall be pleased to give you an account to of them when I see you next。
Sincerely yours,
Tom
