(B) Do you know why different animals or pests have their special colours? Colours in them seem to be used mainly to protect themselves.
Some birds like eating locusts. but birds cannot easily catch them. Why? It is because locusts change their colours together with the change of the colours of crops. When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown colour as crops have. Some other pests with different colours from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.
If you study the animal life, you'll find the main use of colouring is protecting themselves. Bears, lions and other animals move quietly through forests. They cannot be seen by hunters. This is because they have the colours much like the tree.
Have you ever noticed an even more strange act? A kind of fish in the sea can send out a kind of very black liquid when it faces danger. While the liquid spread over, the enemies cannot find it. And it immediately swims away. So it has lived up to now though it isn't strong at all. 根据短文内容, 指出能完成所给句子或回答所提问题的最佳答案。 ⒍ From the passage we learn that locusts ___ .

(C) 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 ducks 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 ducks' legs at once and said, "Whose is that bag?" Nobody answered. The policeman repeated the question, and said, "I'll have to take it away from the owner. Food mustn't be taken out of the country." "Well, then," said the small man with a fat stomach. "Hurry up and take it. We want to go home." The policeman took the bag and went on to the next carriage.
At the next station, when they were safely across the frontier, the small man got up, smiled at the other passengers and said, "I hope 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 tightly (紧紧地) 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 hands, a policeman came up to him, saying, "Hey, man! Foreign food mustn't be brought in." 根据短文内容, 指出能完成所给句子的最佳答案。 ⒒ The small man put the bag in the middle of the floor ___ .
