【正确答案】Dear Sirs,
On 01/01/2006, I took flight CA983 from Beijing to Los Angeles. When the flight arrived at Los Angeles, because of my carelessness, I left my handbag, a black leathered bag, on my seat. There are some important things in it, including my passport, ID card, credit card, some checks and one thousand US Dollars. But the most important thing is my business address book, in which are records of all my clients' phone numbers and appointment agenda in the following two weeks.
In great anxiety I write to you for help. I hope you could help me retrieve my lost bag. I would be most grateful if you could find it for me.
Yours sincerely,
Li Ming
