Dear Mary,

Thanks for the photo of your family. Here is a photo of my bedroom. Look at the photo. A bed, a desk, a chair, a bookcase and a computer are in my bedroom. My bed is yellow. The desk is beside (在……旁边) the bed and it is black. An English dictionary and a Chinese dictionary are in the bookcase. My math, English and Chinese books and the computer are on the desk. My pencil box is in the desk. My pens and rulers are in the pencil box. My schoolbag is on the chair. My brother's white baseball and my sister's computer game are under my bed, but you can't see the baseball in the photo.

Yours,

Bill
