Dear Tom,
Thank you for your letter(信). Today I go to Mr. Green's Clothes Store with my mother. People can buy shirts, trousers, shorts and so on at great sale. It has lots of T-shirts for boys and girls here. They are nice and cheap(便宜的). (A)How much are they? They're only 50 yuan. I also see some skirts in red, green and white. I like them (B) much. I meet my math teacher Miss Wang in the store. She is Mr. Green's friend. With(C)her help, my mother buys a white T-shirt and a red skirt (D)only 40 yuan. I'm very happy.
Yours,
Lucy
