Do you know why different animals or pests(昆虫) have their special colors? 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 have. Some other pests with different colors 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 coloring is to protect themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters(猎人). This is because they have the colors much like the trees.

　　Have you ever noticed an even stranger 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 immediately swims away. So it has lived up to now though it is not strong at all.

If you don’t use your arms or your legs for some time, they will become weak; when you start using them again, they will gradually（逐渐地）become stronger again. Everybody knows this. Yet many people do not seem to know that it is the same with our memory.

　　If a friend says that his arms and legs are weak, we know that it is his own fault. But if he tells us that he has a poor memory, many of us think that his parents are to blame（责怪）, and few of us know that it is just his own fault.

　　Have you ever found that some people can’t read or write but they usually have better memories? This is because they can not read or write and they have to remember things; they can not write them down in a little notebook. They must remember dates, names, songs and stories; so their memories are being exercised the whole time.

　　So if you want a good memory, learn from these people: practice remembering.
