In nature, you may see many insects (昆虫)and animals of different colors. Have you ever wondered why?
Locusts are super delicious food for birds,but it is not always an easy job for birds to catch them.It is neither because locusts are good jumpers or runners nor because they are smarter than their enemies. The reason is that the colors of locusts change with the colors of crops(庄稼). When crops are young,locusts look green. But when autumn comes, locusts change to the yellow and brown color as crops do.
Brown bears,tigers and other animals move quietly through forests. They can’t be seen easily by their enemies. This is because they have colors similar to the trees. For the same reason, polar bears that live on a land of snow and ice are white. Butterflies and bees living among the flowers are colorful like flowers. Soil insects are mostly dark-colored and they live under the soil(土壤) in a dark and wet environment. However, insects with colors different from plants can easily be found and eaten by others. So in order to survive,they have to hide themselves in the daytime and appear only at night.
Have you ever noticed some even stranger acts? The ink fish in the sea can send out some very black ink when it faces danger. As the ink spreads over , its enemies will find themselves suddenly in a dark world. At the same time the ink fish immediately swims away. That is how it keeps itself safe though it is not strong at all.

When you watch TV programs about wild animals, it is surprising to see how an antelope (羚羊) can run away from a strong lion. In the wilderness, everyone has his own way to protect himself. Even plants have their own ways to fight off enemies.
Over millions of years, plants have developed their own defense system (防卫系统). Chemicals are fantastically used by plants to survive (幸存). By making their leaves, flowers, roots and fruits poisonous (有毒的) to enemies, plants can fight back.
One such plant is the Golden Wattle tree. The British scientist David Cameron has found when an animal eats the tree’s leaves, the amount (数量) of poison increases in the other leaves. “It’s like the injured leaves telephoning the others to fight together against the enemy,” he said.
The tree also sends defense messages to neighboring plants by giving out a special smell. Golden Wattle trees in the nearby 45 meters will get the message and produce more poison within 10 minutes. Now, if an enemy eats too many of the trees’ leaves, he will die.
Every kind of plant or tree is good at producing a special set of chemicals. Herbivores, like rabbits, can safely eat the leaves of one tree, but they may be poisoned by its neighbor.
In this way, plants have not only developed their own defense system, but also shared it with others. This makes it impossible for a single animal to destroy even a small area of forest.
小题1:From the first 2 paragraphs, we can learn that _________.
A.plants can do nothing against their enemies
B.chemicals are quite useful for plants to survive
C.an antelope can always run away from a strong lion
D.leaves, roots, flowers and fruits of plants are poisonous
小题2:If animals eat one Golden Wattle tree’s leaves, the tree can________.
A.kill the animals with a special smell
B.tell other trees to come to protect it
C.warn other trees against the animals on the phone
D.send defense messages to the neighboring plants
小题3:The underlined word “herbivores” in the 5th paragraph probably means animals which _____.
A.produce poisonB.live on small animals
C.like to eat rabbitsD.feed on plants or grass
小题4:The last paragraph of the passage suggests that this kind of defense system is ________.
A.bad for animals B.good for forests
C.helpful to some animalsD.harmful to forests
小题5:The passage is mainly about __________.
A.the examples of protecting forests
B.the balance between animals and plants
C.the ways of plants fighting against enemies
D.the relationship between lions and antelopes
