Question

【题目】阅读下面材料, 从每题所给的A, B, C, D四个选项中选出最佳选项。C
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 wild, everyone has his own way to protect himself. Even plants have their own ways to fight against their enemies.
Over millions of years, plants have developed their own way to protect themselves. Chemicals (化学物质) are used by plants to live. 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, and the number of poisonous chemicals becomes more in the other leaves. "It's like the injured (受伤的) leaves telling the others to fight against the enemy together," he said.
The tree also sends messages to plants near it by giving out a special smell. Golden Wattle trees in the nearby 45 meters will get the message and produce more poison in 10 minutes. Now, if an enemy eats too many of the trees' leaves, he will die.
Every kind of plant is good at producing special chemicals. Animals that feed on plants or grass, like rabbits, can safely eat the leaves of one tree, but they may be hurt by its neighbor.
In this way, plants have not only developed their own way to protect themselves, but also shared it with others. So it's impossible for a single animal to damage even a small area of forest.
（1）What's the function (功能) of the first paragraph?
A.To use an example to lead to the main idea of the passage.

（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 people to fight against the animals
D.send messages to the plants nearby to protect themselves
（3）How long can a Golden Wattle tree produce more poison when it gets the message from the plant 45 meters away from it?
A.For about an hour.
B.In ten minutes.
C.For fifteen minutes.
D.For more than ten minutes.
（4）What do you think of the plants' way to protect themselves?
A.It's bad for human beings.
B.It's good for forests.
C.It's helpful to some animals.

【解析】文章大意：文章主要讲述了每种动物有保护自己的方式。每种植物也有和它们的敌人作斗争的方法。植物通过化学物质活着。通过使它们的叶子、花、根以及果实对敌人有毒，植物能够回击敌人。树也通过发出一种特殊的味道发送信息给它周围的植物。因此对于单一的动物伤害甚至一小片树林都是不可能的。
（1）归纳总结题。根据第一段 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 wild, everyone has his own way to protect himself. Even plants have their own ways to fight against their enemies.可知作者利用第一段导出主题植物也有保护自己的方式。故选A。
