Amy is twelve years old today. She is having a birthday party. There are many friends at the party. They all come with different gifts(礼物). Mary gives her a nice doll. Sam brings a good picture book. Joe buys her a CD of Jay Chou (周杰伦).Amy likes the CD best, because Jay Chou is her favourite pop star(流行歌手). They are singing and dancing at the party. They all have a good time.
