1、因未能踐約赴宴致歉Unable to keep one's promise
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
親愛(ài)的南希小姐：
小兒上周六突然生病，因此未能應(yīng)約赴生日宴，殊覺(jué)抱歉，希原諒，再見(jiàn)。
2、因遲復(fù)來(lái)信致歉Because of answering one's letter late
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

這次出去旅行飽覽了許多美麗景色，下次見(jiàn)到您時(shí)，將告訴您一切。
