感谢信是对收信人的某一行为表示感谢。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。
感谢信的写作策略：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。

dear kevin,
i am writing this letter to thank you for the guidance you have offered me during the past weeks. i was a perfect stranger when arriving this city, even not knowing the way to the downtown area. as you know this is the first time for me to come up to this big city.
i bought a guidance book, but there were still difficulties in going around the city. the streets and shops puzzled me so much that i would rather stay indoors. it is your valuable guidance that has enabled me to go about the city without losing myself. i thank you very much for your kind help. yesterday i went downtown alone to buy some stationery and other stuff.
lessons will begin in a few days. i will come over to see you some day next week and tell you everything that has happened to me.
yours sincerely,
li ming

亲爱的凯文：
很感谢你在过去的几周中给我提供的指导和帮助。在刚来这个城市的时候我完全是一个陌生人。我甚至不知道怎么到市区。你知道的这是我第一次来这么大的城市。
我买了一本城市指南，但是我依然发现在这个城市中有很多困难。街道和商店都让我很迷惑，于是我就只能待在家里。是你给我的宝贵向导让我能在这个城市中外出不会迷路。很感谢你的帮助。昨天我就独自一人到市中心购买了一些文具和其他用品。
再过几天，我们就要开课了。下周的某个时间我再来看你，告诉你我这里发生的一切。
