Look at this picture! It's a picture of a room. What can you see in the picture? I can see an apple on the table. Can you see an English book on the table? No, I can't. Where is it? It's in the schoolbag! The schoolbag is on the chair next to  the bed. What is next to the table? Oh, it's a bookcase. Some books are in it. Look! What's that under the chair? It's a cat. A ball is beside  the cat. The ball is mine. It is a volleyball. I like playing volleyball very much. Where can you see the ball?
Under the table. Under the bed. Beside the cat. Beside the chair.
