Look! A bed, a desk, a chair and a bookcase are in my room. My bed is blue and it is near the window(在窗户附近). My desk is near the bed and it’s black. My books and computer are on it. An English dictionary is on the bookcase. Where is my pencil box? It is in the desk. My two pens and three rulers are in the pencil box. My school bag is on the chair. My brother’s white baseball is under my bed. And you can see a dog in the photo. Its name is Sam.

My room is tidy, isn’t?

Yours,
