Do you know why different animals or pests(昆虫) have their colors? They have the colors 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（收获）time comes, locusts change to the same brown color as crops have.Some pests with different colors from plants are usually in danger because others can easily find and eat them.So they have to hide themselves for lives and appear only at night. (18)If you study the animal life,you'll find that the main use of colors for animals and pests is to protect themselves. Bears, lions and other animals move quietly through forests. Hunters cannot easily find them because they have the colors much like the trees. Do you ever find an even more strange act? (19)A kind of fish in the sea can send out a kind of very black liquid (液体) when they are in danger. While the liquid spreads over(散开),their enemies(敌人)cannot find them. And they can swim away easily.

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（收获）time comes, locusts change to the same brown color as crops have.Some pests with different
colors from plants are usually in danger because others can easily find and eat them.So they have to hide themselves
for lives and appear only at night.
(18)If you study the animal life,you'll find that the main use of colors for animals and pests is to protect themselves.
Bears, lions and other animals move quietly through forests. Hunters cannot easily find them because they have the
colors much like the trees.
Do you ever find an even more strange act? (19)A kind of fish in the sea can send out a kind of very black liquid
(液体) when they are in danger. While the liquid spreads over(散开),their enemies(敌人)cannot find them. And they
can swim away easily.
