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.

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

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

3.The underlined word “herbivores” in the 5th paragraph probably means animals which _____.

A．produce poison                                     B．live on small animals

C．like to eat rabbits                                       D．feed on plants or grass

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 animals                        D．harmful to forests

5.The passage is mainly about __________.

A．the examples of protecting forests

It is good to keep animals in zoos. Zoos are places for people to see many different kinds of animals from all over the world. Without zoos, most people would never see a real tiger or bear. Secondly, zoos look after the animals very well. The animals are always given food and cleaned on time. In the wild, it is not always possible for an animal to find food, so sometimes it goes hungry. Thirdly, zoos protect the animals. They offer them safe place to live in. In the wild, some kinds of animals are in danger of becoming extinct （灭绝).But zoos give these animals a chance to live. Without zoos, there would be fewer kinds of animals in the world.

However, some people think it is unnatural (非自然的) and unfair（不公平的） to keep wild（野生的） animals in cages. Most animals are kept in cages that are too small for them. The animals such as bears and tigers always look sad in cages. Wild animals should look for their own food. Anyone would not feel happy if he isn't allowed (允许) to go outside his home and animals don't like it either.

判断正误(正确T错误F)

1.If you don't go to a zoo, you can't see dogs.

2.In the zoos, all animals are happy.

3.In the wild, animals look for their own food.

4.According to（根据) the last sentence, we can say animals like to stay in the cages.

5.The writer is not sure whether it is better for animals to stay in Zoos.
