Dear Mr. Smith,
I am indeed very sorry that I missed the examination on International Business English Writing you gave last Friday. I feel awful about it and want you to know what happened that day. I suddenly fell sick early that morning and my parents had to send me to the hospital. Please find enclosed a copy of the medical bill.
I sincerely hope you can understand my situation and accept my apology. I would appreciate your allowing me to take a make-up examination. I will come to your office during your office hour on Monday to discuss this possibility with you. Once again, I apologize for any inconvenience caused.
Sincerely yours,
Wang Hua

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

Dear Miss Nancy,
Much to my regret I was unable to keep my promise to attend your birthday party last Saturday, owing to the fact that my little son was suddenly taken ill early that day.
Hoping to see you soon.
Truly yours,
Tom
