【正确答案】 Dear Bob,
This is Li Ming. I am writing to express my apology because I lost the book you lent me last week.
Last week, while I was reading in the library, I answered an emergency call and hurried to deal with an important matter. I was in such a hurry that I forgot to bring the book, and it had disappeared when I came back. It is my carelessness that resulted in such a situation. Therefore, I am willing to shoulder the responsibility. I decide to buy a new one as compensation, but I wonder whether it is acceptable to you. Please don't hesitate to tell me if you have better solutions, I am willing to cooperate.
I apologise again for the inconvenience I may bring. It would be highly appreciated should you take my letter into serious consideration. I am looking forward to your reply.
Yours sincerely,
Li Ming
