Answer 1

Dear Mr. Brown,
I’m now safely back home. Thank you very much for all the kindness I got from you during my stay. Hope everything is fine with you there. Now I wonder whether I could ask you a favor. 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 sincerely,
Li Hua
