雅思英語作文：遺失信－－財(cái)物遺失在民航班機(jī)上,寫信給機(jī)場(chǎng)海關(guān)請(qǐng)求幫助

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 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 record all my clients'phone numbers and appointment agenda 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 meticulous and warmhearted help will be greatly appreciated.
　　For information about my lost thing, please contact me in the following ways.
　　Mobile phone: 13901160626
　　Home phone: 82326258
　　Office phone: 82326255
　　Yours sincerely
　　Will Smith
