     It was a Saturday morning in May. When Mrs Edwards opened her curtains (窗帘) and looked out,

she smiled and said, "It's going to be a beautiful day." She woke (唤醒) her small son up at eight-thirty

and said to him, "Get up, Teddy. We're going to go to the zoo today. Wash your hands and face,brush

your teeth and eat your breakfast quickly. We're going to go to New York by train."

the zoo in your dream?" Teddy laughed and answered, "You know, Mommy! You were there in my dream

too."
