Scrooge was a businessman.One night,his dead business partner Jacob Marley walked through the wall. "Jacob!" cried Scrooge. "Why are you here?""When I lived,I should have cared about people," said Marley. "But I did not,so I must do it now.Scrooge!You are far worse than I was!You too will become restless （不安）,unless you change!Tonight,three spirits will visit you.Only （A） they can help you to change!" cried Marley. "Learn from them!" Then he stepped out of the window.
At one o\’clock,Scrooge woke.Near his bed stood a strange figure （人影） as small as a child,but with long white hair and a wise old face. "I am the Spirit of Christmas Past," it said quietly.The Spirit led him to a school.The school boys laughed,and wished each other a merry Christmas,as they travelled to their homes for the Christmas holiday.Inside,in the long,cold,silent classroom,a lonely boy sat reading near a small fire.When he saw his poor forgotten past self,Scrooge sat down and cried."Poor boy!I （B） wish-but it\’s too late now.""What\’s the matter?" asked the Spirit. "There was a boy singing Christmas carols（颂歌） at my door yesterday.I\’m sorry I didn\’t give him anything." Hearing this,the spirit smiled,"Let\’s see another past Christmas!"
The schoolroom became darker and dirtier.There was the young Scrooge again,a little older and bigger than before.He was not reading this time,but was walking up and down,looking very unhappy.The door opened,and a little girl,much younger than him,came in.Putting her arms round his neck,she said lovingly to him, "I\’ve come to bring you home,dear brother!Father is so much kinder than he used to be!I asked him if you could come home,and he said yes!And we\’re going to spend Christmas together!"
