An E-mail to Mr. Brown
Dear Mr. Brown,
I have got back home this night, and now I would like to show my thanks for your help during my stay in America. I really had a happy learning life. Thanks again.
I am sorry to say that I have left an English dictionary there, which means a lot to me. It is a priceless gift from my American teacher. It will be appreciated if you can find and send it to me. I guess it may be on the bookshelf in the room I stayed before. By the way, I will pay the postage fee.
