根据短文内容完成下列各题。

     Yesterday evening, when I went to town with my mother, we met a strange man. It was raining hard and we had no umbrella. We were trying to get into a taxi when he came up to us. He was carrying a nice umbrella and he said that he would give it to us for only a pound. He said he had forgotten his wallet and needed taxi-fare(出租费) to go back home. My mother didn’t believe what he had said at first, and asked him a lot of questions. But she finally believed the man and gave him the pound. She was happy to have a good umbrella for so little. But the man didn’t get into a taxi. We followed him and found he went into a pub(酒吧) and bought himself a glass of whiskey(威士忌) with the pound.
