假设你是刘杰，作为选派的交流学生在美国某中学学习了一年，寄住在Mr. Smith家里，刚回到国内。回国后你发现自己的一本英语词典遗忘在他家，因此给他写一封信，请他帮助寄回词典。信的主要内容如下：
* 感谢在美国期间他所提供的帮助。 * 一本英语词典忘记带回。
* 词典是美国老师送的，非常珍贵。 * 词典很可能丢在卧室的书架上。
* 邮资自己付。
注意：1．词数100左右。
2．可适当增加细节，以使行文连贯。
3．参考词汇：邮资—postage 书架—bookshelf
Dear Mr.Smith，
I have arrived safely back in China. Thanks again for all your help and kindnessduring my stay in US. You really made sure I had a safe and enjoyable time. I hope you are well and that everything is fine with you.
Unfortunately, I have a very small favor to ask. When I got back to China, I checked my bags and realized that I had left my English dictionary at your house. This was a gift to me from my American teacher and I treasure it dearly. I wonder if you would mind sending it back to me. Of course, I will happily pay for any postage.
I last saw the dictionary on the bookshelf in my bedroom. It has a red cover so it should be easy to find!
Thanks in advance.
Yours, Liu Jie
