    Hi, I'm Mark. Today is 20th May. It's my tenth birthday. I like green best. In my room, there's a green desk, a green bed, a green chair and some green toys. So I have a "green party" today. My father gives me a green ball and my mother gives me a green model ship. Look, my mother is making a birthday cake for me. I want my friends to come to my party. We can sing and dance. My party begins at six o'clock. I can't wait.
