Colors in them seem to be used mainly to protect themselves. Some birds like eating locusts(蝗虫), but birds cannot easily catch them. Why? It is because locusts change their colors together with the change of the colors of crops(庄稼). When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color as crops are. Some other pests with different colors from plants are easily found eaten by others. So they have to hide(躲藏) themselves by day and come out only at night. If you study the animals’ life, you’ll find the main use of coloring is to protect themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters. This is because they have the colors much like the trees. Have you ever found an even more strange act? A kind of fish in the sea can send out a kind of very black liquid(液体) when it faces danger. While the liquid spreads over(散开), its enemies(敌人) cannot find it. And it swims away at once. So it has lived up to now though it is not strong at all. ( ) 1. From the passage we learn that locusts ___________. A. are small animals B. are easily found by birds C. are dangerous to their enemies D. change their colors to protect themselves ( ) 2. How can pests with different colors from plants keep out of danger? A. They run away quickly. B. They have the colors much like their enemies. C. They hide themselves by day and come out at night D. They have to move quietly. ( ) 3. Bears and lions can keep safe because ______________. A. they have the colors much like the trees B. they move quietly C. they like brown and grey colors D. they live in forests ( ) 4. Why can the kind of fish live up to now? A. Because it is very big and strong. B. Because the liquids it send out can help it. C. Because the liquid it sends out can kill its enemies. D. Because it swims faster than any other fish. ( ) 5. Which is the best title for this passage? A. The Change of Colors for Animals and Pests. B. Colors of Different Animals and Pests. C. The Main Use of Colors for Animals and Pests. D. Some Animals and Pests. 以下是对该练习题的解析： ### 一、单词拼写 1. kinds 2. seriously 3. magician 4. common；talented 5. example 6. poor 7. performers 8. role ### 二、单项选择 1.
