    Danny is a schoolboy. He is from the USA and he is 12 years old. This is his room. Let's have a look. His computer is on the desk. And a telephone is on it, too.

    His books are everywhere. Some are in the bookcase and some are on the ground. Look! What's that under the bed? Oh, it's one of his socks (袜子). Where is his schoolbag? It's on the ground. You can find a dictionary, a pencil box and a set of keys in it. Where is his hat? Can you find it?
