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 dont 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
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.
Sincerely yours,
Tom
Dear Alan，
Im writing to apologize about last Thursday。 I am terribly sorry that I didnt go to see you， for I lost my wallet。 Anyway， I found it。 But it was too late for the train。 I had to take the bus。 What a pity that I took a wrong one。 It went to Milford。 There， I waited for half an hour for a zuowen.zk168.com.cnbus to Driffield。 It was much worse that on the way to your home， the bus broke down。 So I just went back home to Pigston。 I really do apologize because I didnt speak to you on the phone， but it wasnt my fault。 I tried several times， but there was no answer。
Anyway， how about next Thursday?
