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 Charlie,
Kindly excuse me for my not being able to see you off at the airport this Saturday as I have promised.
A major business partner of our company will be attending an important conference in Xiamen this weekend, and my boss finally chooses me to accompany him there to negotiate about a new transaction. I have just been informed of this plan and am happy about the decision—this is an opportunity to both display and enhance my abilities, so I am afraid I cannot be present at the airport.
Pursuing study overseas is an essential step in the accomplishment of your dream.
How I wish I could have the chance to share with you my personal feelings and suggestions before you are away! I hereby send you a gift to wish you good luck. Please forgive me.
Cordially,
Li Ming
