英语作文。急

感谢在美国期间，b提供的帮助，一本英语词典忘记带了，词典是美国老师送的。非常珍贵，词典可能丢在卧室的书架上，邮资自己服。

Dear Bob,

Thank you for helping me in America.But now I'm terribly sorry to tell you that I forget to take my English dictionary with myself.The English dictionary is very precious,cause it is sent by an American teacher.I still remember that maybe I place it on the shelf.Anyway,could you please post it for me?I will pay the post money for it.

Thanks again!

Yours

Jim
