英语作文,李华做交换生的求助信假如你是李华，作为一名交换生在美国某中学已经学习了两周但是在生活和学

Dear Mr. Brown,
I'm now safely back home. Thank you very much for all the kindness I got from you during my
stay in America. Hope everything is fine with you there.
Now I wonder whether I could ask you a favour. When I came back, I suddenly realized that I
had left my English dictionary behind at your place. It is a precious gift from my American teacher.
Would you please be so kind as to send it back to me? I'll pay for the postage. The dictionary must
be on the bookshelf in my bedroom. It is the one with a red cover.
Thanks and all the best.
Yours,
Li Hua
