It was nine on a cold winter night. I hurried to go home from work on my motorbike.

At the last crossing, while I was waiting for the green light, I saw an old man _________ toward me. He _________ me and I felt a little nervous. The old man said slowly, “Excuse me. Could you please help me?” I looked at him up and down. He seemed to be about _________.

The old man took out a 10 yuan and said to me, “Do you see the old lady _________ is selling baked (烤) sweet potatoes over there? Could you just take the money and help me _________ one from her?” He pointed at an old lady selling something about fifty meters away in the corner.

“But why don’t you go and buy it by yourself?” I was puzzled (困惑的). The old man continued, “That old lady 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 sweet potato left and she wouldn’t go home _________ all the sweet potatoes were _________ out. But I know she can’t stand the cold because her legs hurt. I’m very worried about her.”

At that time, I felt really warm and _________. Without taking the money, I rode to the old lady _________ and bought the last one. As I waved goodbye to the old man, I see him standing there __________ a thankful smile.
