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

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 Anne,
Thank you for your invitation to dinner at your home tomorrow evening.
Unfortunately, it is much to my regret that I cannot join you and your family, because I will be fully occupied then for an important exam coming the day after tomorrow.
I feel terribly sorry for missing the chance of such a happy get-together, and I hope that all of you enjoy a good time. Is it possible for you and me to have a private meeting afterward?
If so, please don't hesitate to drop me a line about your preferable date. I do long for a pleasant chat with you. Please allow me to say sorry again.
Regards, Li Ming
