4.遗失信----财物遗失在民航班机上,写信给机场海关请求帮助
    Dear officer:

    In 01/01/2000, I took flight CA983 from Beijing to Los Angeles. When the flight arrived at Los Angeles, because of my carelessness¹, I left my handbag, a black leathered bag, on my seat. There are some important things in it, including my passport, ID card, credit² card, some checks and one thousand US Dollars. But the most important thing is my business address book, in which record all my clients’phone numbers and appointment agenda³ in the following two weeks.

    Since this bag is very important to me, my friends told me that I should contact your department to seek help, so I write this letter to you anxiously. Hope you and your staff can help me find my lost bag. Your meticulous⁴ and warmhearted help will be greatly appreciated.
