It was nine on a cold winter night.I was going home from work on my bike.At the last crossing，while I was waiting for the green light，1 saw an old man walking to me.I felt a little nervous. "Excuse me，" the old man said. "Could you please help me？" I looked at him up and down.He seemed to be about 70 years old.
   Hearing "yes"，he took out 10 yuan and said to me， "Do you see the old woman selling baked sweet potatoes（烤紅薯） over there？Could you use the money to buy one from her？" ①He pointed at the old woman about fifty meters away.
   "Why don't you go and buy it yourself？" I was puzzled and asked. "She is my wife and it's her first day to sell baked sweet potatoes.Just now I called her.She told me that there was only one baked sweet potato left.She won't go home until she sells it out.But she can't stand the cold because her legs hurt.②我很擔心她。"The man said to me.
   At that time，I understood everything.I was very touched by his words and felt warm.Without taking the money；I rode to the old woman quickly and bought the last one.
