因未能及时还书致歉unable to return borrowed book on time
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
亲爱的凯特：
我迟迟未能归还您的那本《鲁滨逊飘流记》，请原谅。该书我读得津津有味。读完后，正预备归还您时，我的表妹来访，见这本书也感兴趣，定要借去一读。为了让别人也能分享您那本书所给予的乐趣，我不能及时归还。我想再延迟些日子奉还，谅您不会介意的。
再次感谢您的慷慨。
汤姆
Dear David,
I am truly sorry that I cannot attend the project meeting to be held on next Tuesday afternoon.
The reason is that I am going to take a business to Shanghai by plane that day, so I will be unavailable for the meeting. However, considering the importance of the meeting, I will be grateful if you could send me a brief record of the project progress by E-mail. I will check the record and send my feedback to you.
Once again, I am sorry for any inconvenience caused. Hope you can accept my apologies and understand my situation.
Yours sincerely,
Li Ming
