Hi! I am Jack. This is a picture of my room. My English book is in the bookcase. My schoolbag is on the chair. Three notebooks and one pencil box are in it. A tape player and some tapes are on the table. What's under my bed? It's my dog. It is white. A computer game is under the chair. But it is not mine. It is my sister Cindy's.
