新航道提供小作文：
Dear Bob,
I am the Chinese student who stayed at your house druing my vacation in Canada. Upon arriving home, I found I had forgotten to return the music CD I borrowed from you. Therefore, I am wrting this letter to express my sincere apologies for my carelessness.
As I understand this CD is one of your favorites, I will try my best to send it back to you as soon as possible. So, could you please tell me where I should send it to? Or shall I send it directly to the place where I stayed? According to the regulations of China’s Postal Services, it will take almost a week to reach Canada.
I am sorry for the inconvenience I may have caused you. Thank you again for the hospitality you offered me during my stay there. Wish you all the best.
Yours sincerely,
Li Ming
