     Hello, everyone! This is my bedroom. That is my green bed. It's very lovely. Isn't it? Can you see the

pink pillow? It's my pillow. I like it very much. The dresser is beside (在……旁边) the bed. It's brown.

And a clock is on the dresser. It's pink and purple. Oh, this is my desk. It's blue. There is a computer on
