It was a Saturday morning in May. When Mrs. Green opened her windows and looked out, she said, “It's going to be a beautiful day.” She said to her son, “Get up, Tom. We are going to the zoo today. Wash your hands and face. We are going to New York by train .” Tom was six years old. He was very happy now, because he liked going to the zoo very much. He also liked going by train. He said, “I dreamed(做梦) about the zoo last night, Mum. ”“And what did you do in the zoo in your dream? ”Tom laughed and answered, “You know, Mum! You were there in my dream too. ”
