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(化学物) are fantastically used by plants to survive . 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.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 |
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 |
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 |
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 |

阅读下列短文回答问题：
The most unusual museum in London is the Science Museum. In most museums, there’s no shouting and no running, and you aren’t allowed to touch the exhibits. But the Science Museum is different… because it’s noisy ! People talk about what they can see and do there, and some of the machines are noisy as well. Visiting the Science Museum is fun and it’s a great way to learn about science because you can work things out and try out ideas.
When I visit the Science Museum, I go to the Launch Pad. This is my favorite room because you can do physics experiments. For example, if you want to fill a bag with falling sand, you have to move a kind of truck on wheels into the correct position. I also go to the Rocket Show. You can learn how we travel into space and back again.
Then I go upstairs to the Human and Nature room. You can compare your speed with animals there. You hear a noise and push a button. If you aren’t fast enough, the lion catches you! I’m faster than all my friends, but the lion still catches me.
You can do a lot of things in this museum, but you have to obey some rules as well. For example, you mustn’t take photos of the exhibits in the museum. But you can buy postcards of them in the museum shops.
Above all, the Science Museum is free. That means you can drop in for a few minutes or you can stay as long as you like – it’s open every day, from 10 am to 6 pm. So if you ever go to London, make sure you visit the Science Museum. It’s my favorite museum in the whole world.Where does Tony go first when he visits the Science Museum?
What can you try out in the Human and Nature room?
How much does it cost to go in the Science Museum?
How long can you stay at the Science Museum ?
What does the writer think of the Science Museum?
Waste can be seen everywhere in the school. Some students ask for more food than they can eat and others often forget to turn off the lights when they leave the classroom. They say they can afford these things. But I don’t agree with them.
Waste can bring a lot of problems. Although China is rich in some resources（资源）， we are short of（缺乏）others, for example，fresh water（淡水）. It is reported that we will have no coal（煤or oil to use in 100 years. So if we go on wasting our resources，what can we use in the future and where can we move？Think about it. I think we should say no to the students who waste things every day. Everybody should stop wasting as soon as possible.
In our everyday life，we can do many things to prevent waste from happening，for example， turn off the water taps（水龙头） when we finish washing，turn off the lights when we leave the classroom，try not to order more food than we need and so on. Little by little, everything will be changed. Waste can be stopped one day, if we do our best. From the passage we know that some students often _______ in the school.
| A．eat too much | B．don‘t work hard |
