Paragraph 1
He got out and ran up to the steps. Then in a short while Jack heard him coming back, but he was not coming fast. He was carrying his little crippled(残疾的)brother. He sat down on the step and pointed to the car.
"There he is, Buddy, just like I told you upstairs. His brother gave it to him for Christmas and it didn't cost him a cent. And some day I'm going to give you one just like it…then you can see for yourself all the nice things in the Christmas windows that I've been trying to tell you about"【高分句型一】(男孩想帮助残疾的哥哥坐车)
Paragraph 2
Jack got out and lifted the boy to the front seat of his car. The shining﹣eyed elder brother climbed in beside him and the three began an unforgettable holiday ride, looking at all those beautiful things. That Christmas Eve ,Jack learned the real meaning of the words: "It's more blessed to give than to receive." He also learned what it means to be "an elder brother like that."【高分句型二】(Jack满足男孩的愿望)
