阅读短文，选择正确答案。 A small man with a fat stomach got on the train at the last station before the frontier (边境). He carried a paper bag. And four feet of ducks (鸭子) could be seen under the cover. The man found an empty seat, put the bag in the middle of the floor, took out a newspaper and began to read. Then a policeman came in. Of course he saw the bag with the ducks' feet at once and said, 'Whose is that bag?' Nobody answered. The policeman repeated the question, and said, 'I shall have to take it away from the owner. Food mustn't be taken out of country.' 'Well, then,' said the small man with a fat stomach. 'Hurry up and take it away. We want to go home.' The policeman took the bag and went on to the next carriage (车厢). At the next station, when they were safely across the frontier, the small man got up, smiled at other passengers and said, 'I hope that they'll enjoy the ducks' feet. The rest of the bag had nothing but rubbish in it.' Then he opened his coat and pointed to another bag he was carrying under it. It was tied over the stomach, which was not really fat. 'I have the rest of the two ducks here,' he said. With these words, he got off the train. But while he was happily walking to the exit with the bag in his hand, a policeman came up to him, saying, 'Hey, man! Foreign food mustn't be brought in.' 1.
