（66）Itwasacoldwintermorning．I was waiting for my train inside the waiting hall．A boy sat nearby．His worn clothes and dirty hands seemed to tell people that he was homeless．"（67）他一定又冷又饿．Maybe I should help him，"I said to myself．Just at that moment，a young man walked towards him．"Excuse me．My wife and I bought two hamburgers but one was enough for us．（68）我们讨厌浪费好的食物． Can you help us？"He handed the boy the hamburger．
The boy thanked him and opened the bag of hamburger wit joy and care．Suddenly he stopped．In the direction to which he looked，I saw an old man in worn sweater，worn trousers and open shoes，entering the hall．The boy stood up and helped the old people to his seat．He said，"A kind man brought me two nice hamburgers and（69）I'vejustfinishedeatingone．I hate wasting．Can you help me？"（70）Heputthehamburgerintheoldman'shands．
Everyone nearby was touched．I rushed into a KFC and took out of my money．It was so cold that day but I felt much warmer than I have ever thought possible．
