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. After he drank it, he put on his hat and took up one of the many wet umbrellas there and went off with the new one. Soon after that, he sold it again.
