参考范文：

Dear Ma Bin,

I would like to apologize for my not being able to return in person the book you lent me last Wednesday. You know, I have done a parttime job as a private teacher. Originally the lessons were scheduled on Saturday. But it happens that my student is going to take part in a football match this Saturday, the day after tomorrow and so the lesson is shifted to tomorrow evening, which renders me to meet you then.

But don’t worry. I have asked a classmate to return that book for me. She is a pretty girl with short curly hair, and will go to your dormitory at 7:00 tomorrow evening.

Thank you again for your book. It is really helpful to my English assignment.

Yours,

Li Ming
