【答案解析】[参考范文] Room 640, × × Hotel Oct. 16, 1981 Dear Sir, I am a citizen of Sweden, now on a tour in China. This is the first time I am in your beautiful country. I naturally feel that everything is interesting and strange. Yesterday when I visited Yuelu Hill, I was greatly fascinated and lost myself in the enjoyment of the gracefulness of nature. Upon my arrival back at the hotel, I found my handbag was missing. There were some important documents and a camera in it. I was very worried, fearing that it was entirely impossible to recover it. At eight o'clock, a charming child accompanied by a hotel attendant came to my room with a bag in his hand. I at once recognized it was mine. I thanked him awfully for his kindness and offered him a reward of 300 dollars. Smiling, he refused to take even half a cent. At my insistence, he told me his name and address when leaving. He is Wang Mingsheng, a schoolboy of Junior 2 of your school. Deeply moved by his selfless spirit, I am writing to commend his noble deed. Please convey my gratitude to his parents. Yours respectfully, Arnold Benson
