Good morning! I'm Bob. This is my house(房子). Look at my sitting room(客厅). The red sofa( 沙发) is very cool, right? In my bedroom(卧室)，there is a computer. I often play computer games on it. Do you like it, too? There is a book and a pencil box on a desk. There is a flower near the sofa. On the wall you can see a picture. It's blue. It's my favourite colour.

    This is my house. What about your house?
