仁爱版初中英语七年级下册 3月第一次月考阅读理解练习附答案 一 Have you wondered why different animals or pests(害虫) have their particular colors? Colors in them seem to be used mainly to protect themselves. Birds, especially seagulls are very fond of locusts(蝗虫), but birds can’t easily catch locusts because locusts change their colors together with the change of the color of crops. When crops are green, locusts look green. But when crops are ripe(成熟), locusts take on exactly the same brown color as crops have. Some other pests with different colors from plants are usually easily found and eaten by their enemies. So they have to hide themselves in terror for lives and appear only at night. If you study the animal life in any part of the world, you will find the main use of coloring is to protect themselves. Bears, wolves and other beasts move quietly through forests. They are usually invisible to the eyes of hunters, because they have the color much like the barks(树皮) of trees. An even more strange act remains to be noticed. A kind of fish living in seas can send out a kind of very black liquid(液体) when it faces danger. While the liquid is sent out, it quickly swims away, and its enemies cannot find it any more. 1．This passage mainly talks about ________.
