Here are two pictures. A man and a boy are in one picture. Who are they? Let me tell you. The man is Mr Smith. And the boy is Mike. He's the man's son. Now they are in the boy's bedroom. We can see some Chinese books on the desk. And on the bed is a shirt. It's Mike's. His trousers are on the bed, under his shirt, too.
Now let's look at the other picture, you can see a woman and a girl in it. The woman is Mike's mother and the girl is her daughter, Angela. In Angela's room, you can see a photo of the Smiths on the white wall. Between the windows, there is a desk. A clock is on the desk. It's eleven. What's that on the floor? Oh, it's Angela's hat. It looks like a black cat.
