答案：Dear Cui Yuan, Thank you so much for your help during those days when I was traveling in your city.（直接表明目的，表达感谢之情） I would not have known how to pass the last 9 days without your kind words to comfort me and your company to help me find my wallet back. I still remember that day clearly when my luggage with all my personal belongings was lost while I was preparing to get off the train.（直接叙事，说明感谢的原因） I knew nothing about what I was going to do next because I was traveling alone at that time and my phone was gone with my luggage. I had no money, no friends and no cards including my ID card at that moment. You couldn’t even imagine how I felt after I was told by the station staff that I might not find my luggage back again. It was you who told me to calm down and went to the police station with me. You are like an angel to me and I really appreciate everything that you had done for me. I would like to invite you to visit my hometown for a vacation and wish to see such a kind person like you again.（做出邀请） I am looking forward to your reply. Sincerely, Jenny[译文]亲爱的崔源： 很感谢我在你所居住的城市旅游时你所提供的帮助。如果没有你的安慰的话语和陪我找到钱包，我真不知道自己要如何度过那剩下的9天时间。 我仍然清楚地记得当我准备下火车时发现我装着所有随行物品的行李找不到的那一天。我不知道接下来要怎么做了。我这次是独自出来旅行而且我的电话和行李一起丢了。没有钱,没有朋友,没有卡，包括我的身份证。你甚至想象不到乘务员告诉我可能再也找不回我的行李时我的感受。是你安慰我要保持冷静，并和我一起去了警察局。你当时对我来说就像一个天使，让我很感激。 我想邀请你来我的家乡游玩，希望可以再次见到这么善良的你。我期待着你的回复。 真挚地， 珍妮
