This is a picture. It's a picture of my bedroom. Look at it, please. What can you see in the picture? I can see a bed, a desk and a chair. What can you see on the wall? I can see a map and a kite. What map is it? It's a map of China. I can see a light, some books and some flowers on the desk. Where are my coats and trousers? Oh, they're in the box. You can't see them.
