　　六 感谢信 (A Letter of Thanks)

　　感谢信通常带有浓厚的感情色彩，具有比较浓的人情味。感谢信通常分为正式感谢信和非正式感谢信，前者行文得体、语气礼貌谦恭、用词正式正规；后者语气则更加亲切热情。

　　写作“三步走”：表达感谢之情并说明原因->提及自己曾受到对方的帮助->再次感谢并表达回报愿望。

　　提示：表达的感激之情要恰到好处，不要过于夸张；建议在结尾尽量表达希望回报对方的愿望，显得更加真诚。

　　范文：

　　Dear Mr. and Mrs. Smith,

　　I am now back to China safe and sound. In this letter I would like to convey my heartfelt thanks to you and your lovely children for your kindness and hospitality to host me when I was in New York. Your generous help and tender care made me feel warly welcomed and transformed my first American trip into a beautiful memory。

　　I do hope that your whole family pay a visit to China in future, so that I could have the opportunity to repay your friendship. I assure you that you would enjoy visiting here as I did at your home。

　　I feel obliged to thank you once more。
