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. B、To show the structure (结构) of the passage. C、To introduce how wild animals protect themselves. D、To raise readers' interest on wild animals.
(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. D、It's harmful to forests.
(5)、What does the passage mainly talk 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.

 阅读下面语言材料,从每题所给的 A、B、C、D 四个选项中选出最佳选项。

John is a student who keeps the phone with him all the time. His dad thinks he is addicted (上瘾的) to the phone, but John doesn't think so. They write to each other.

Dear John,

It's reported that fifty percent of the teenagers depend on their phones too much. I think you have this problem too. That's why I think you should give up your phone. Not forever, just for a week. I'm warned that you are developing some bad habits. Yon keep your phone with you all the time—you even check the basketball scores at the dinner table. It's not a good idea to use your phone while you are doing homework Because you can't put your heart into your homework at all. And you may make more mistakes when you can't fully put your heart into it.

Love

Dad

Dear dad,

I know you think I depend on my phone too much. But my phone helps to make my life better in many ways. Do you remember that time when the car broke down? I sent a message to tell you that I was going to be late. If I didn't, you would be worried about me for hours. My phone helps me with my homework too. I can look up anything in a second. It's really hard to be successful today if you don't have a phone. Social media, games, and apps might seem silly to you, but they help me to keep in touch with my friends. I promise to cut back my phone use, and I won't use it at the dinner table any more. But giving it up for a week wouldn't change anything in the long term.

Love

John
