It was a cold winter day. I rushed down the busy road towards the bus stop. Taxis passed m

e one after another【C1】______I didnt have enough money to get one. My wallet was in my pocket but all that I【C2】______was a five-yuan note. Taking a bus would【C3】______three, so I would be left with only two yuan to buy something to【C4】______. I was very【C5】______as I had only eaten one meal all day. Waiting at the bus stop, I【C6】______eagerly for a store from which I could buy food. Then I heard an old womans voice【C7】______behind me, "Steamed corn(蒸玉米)! Steamed corn! One yuan each!" Her voice was breaking and【C8】______deep despair. Staring at the old woman, I felt pity. She was【C9】______, just like a beggar. But she was much older than the other beggars in the street. Her face was【C10】______and her eyes were full of tears. Her large withered(干枯的)fingers kept a tight hold on her basket of steamed corns. What had happened to her？ Why was a woman【C11】______her age selling corns on such a cold evening？ I felt sad. I had to do something. I took the five-yuan note from my wallet and handed it to her. She had said each steamed corn cost one yuan, so I could【C12】______five. But if I did that, I would have nothing【C13】______to pay for the bus ticket. I wouldnt be able to get home. Finally, I decided to give the woman two yuan for one steamed corn, to【C14】______my pity for her. To my surprise, she refused to accept the【C15】______one yuan, saying she wanted to work for her money. She was already【C16】______to me because I was the only person to buy steamed corns from her all day. I was【C17】______moved. She was so old and weak but chose to sell snacks rather than【C18】______. From that moment, I had【C19】______for her, and didnt feel pity any more. The corn was sweet and delicious. But【C20】______made me happier was that I had helped a respectable old woman as much as I could.
