We are interested in the preservation of the biodiversity on Earth. What I’ve been working on is rats. Just looking at rats, you can understand continental drift and climate change. We’ve actually rediscovered rats that were thought to be extinct. Darwin was the last one to document them on the Galapagos Islands. People have gone there for hundreds of years and not seen one. In 1997, I went there with my mentor(导师) and another graduate student. Everyone thought I was crazy, why look for something that doesn’t exist? They wouldn’t even give us permits. Our plan was to stop on a beach for a day and then hike up to the top of an extinct volcano where very few people had been:We were on a picturesque, isolated beach. We set out the traps just to see what we might find. The next morning, I checked my traps! I immediately ran back to my mentor. When he looked in the mental trap—I will never forget his face--- It looked like he’d seen a ghost.

I certainly understand the argument: “ Who cares about an extinct rat?” but you have no idea what role that rat plays in that functioning ecosystem. People can appreciate beauty, so that’s why people love pandas and want to keep them around. You never hear, “What good is panda?” Ecologically, these rats are much more important to their ecosystem than those pandas--- not that I don’t love pandas but we have to look beyond the big and beautiful.

I teach conservation biology and evolution. In both you have to appeal to people asking “ Why is this important to me?” Some scientists refuse to do that. That’s my entire approach. I’ll ask “How many of you had a family member who was in a tornado, hurricane or flood?” .And almost every hand goes up. Climate change is suddenly very personal, and now they want to hear what you are saying. You are not looking for sympathy for the rats but for a greater understanding of the system.

C

There is not enough oil in the world now. As time goes by, it becomes less and less, so what are we going to do when it runs out? Perhaps we will go back to using horses, carriages and bicycles.

In the Second World War, some people didn’t use gas made from petroleum (石油) in their cars. They made gas from wood and plants instead. The car didn’t go fast, but they ran, so this was better than nothing. However, in the future, we can’t cut down all our trees to make gas; we need our trees for other things, too.

Besides different types of gas, we can also use electricity to run our cars, but first we must make the electricity! Some countries have coal and they make electricity with that, but we might not always have coal, either. Other countries have big, strong rivers, and they can use the power of water to turn turbines (涡轮机) and make electricity more easily and cheaply.

We are also able to get power from the ocean tides. We put turbines into the mouth of the river. Then the tide comes in, the water turns the turbines and then it goes out, it turns them again.

Which of these ways will be used to run our cars in the future?

49. When might people have to go back to using horses and carriages?

A. When they are poor.                                    B. When they run out of oil.

C. When they need more exercise.               D. When there aren’t any big trees in the world.

50. What did some people use to make gas in the Second World War?

A. Water                         B. Coal                        C. Wood and plants          D. Tides

51. How many ways are suggested to make electricity in the passage?

A. 2                                 B. 5                             C. 4                                      D. 3

52. The passage is mainly about ________ .

A. how to run our cars                                          B. what to do when oil runs out

C. different types of gas                                  D. the ways to make electricity

Where we live, on the eastern shore of Maryland, the gentle waters run in and out like fingers slimming at the tips.

The Canada geese know this place, as do the white swans and the ducks. In autumn, they come home for the winter. Once or twice each year, snow and frozen rain move into the area. When this happens, if the river is at its narrowest, there is a freeze which hardens the water to ice.

One morning, a friend of mine set the breakfast table beside the huge window, which overlooked the Tred Avon River. Suddenly she leaned forward and cried out, “There is a goose out there.”

We saw the figure of a large Canada goose, very still, its wings folded tight to its sides, its feet frozen into the ice.

Then from the dark skies, she saw a line of swans. They floated from the top of the sky downward and at last landed on the ice. My friend was on her feet now, with one hand against her mouth, unbelieving. As the swans surrounded the frozen goose, she feared that life it still had might be pecked(啄) out by those great swan bills.

Instead, those bills began to work on the ice. The long necks were lifted and curved down, again and again. It went on for a long time. At last, the goose’s head was lifted. Its body was pulled. Then the goose was free and stood on the ice. And the swans stood in the air watching. Then, as if it had cried, “I cannot fly.” Four of the swans came down around it. Their powerful beaks chipped off the ice held in the feathers. Slowly, the goose spread its wings as far as they would go, and moved slowly into the sky.

This is a true story. I just think of it in the bad moment, and from it comes only one hopeful question: If so for birds, why not for man?

1.Which would be the best title for the passage?

A. Why Not for Man?　　　　 B. Graceful Swans

C. Swans’ Brave Act　　　 D. I Just Couldn’t Believe It!

2.What happened to the Canada goose?

A. It was deserted by other geese.

B. It was stuck in the ice.

C. It was wounded and couldn’t fly.

D. It was lost in the water.

3.At first the author’s friend was worried that________.

A. the swans would not help the Canada goose

B. she didn’t care about this matter any more

C. the swans wouldn’t identify with the Canada goose

D. the swans would peck the Canada goose to death

4.What did the swans do when they saw the Canada goose couldn’t fly?

A. They chipped off the ice held in its feathers.

B. They waited patiently for the ice held in its feathers to melt.

C. They came down and lifted it up to the sky together.

D. They stayed with it and protected it.

In space, there is no up or down. Without the gravity that we experience on Earth, as-tronauts and everything else on a spaceship float freely.

Humans can experience the sense of zero gravity without going into space. How？A zero-gravity flight. When an airplane flies in a lot of parabolas（抛物线）, a man-made zero-gravity environment is set up. Everything in the plane floats, even passengers.

Gravity has an effect on everything from the human body and mind to the behavior of plants and the way machines run. Space travel is expensive and dangerous. But zero-gravity flights let scientists conduct experiments in an environment that mimics（模拟） the conditions of space. On each of its research trip, Zero-G flies about 30 parabolas, each of which creates a period of weightlessness that lasts about 30 seconds. Nikolaus Kuhn of the University of Ba-sel, in Switzerland, flew with Zero-G. He was conducting an experiment about soil and the flow of water on Mars. The Red Planet has about one-third of the gravity that Earth has. This means water flows more slowly on Mars. By making the parabolas less steep, zero-gravity flights can make the feeling of Martian gravity. Flying with Zero-G has been necessary for Kuhn’s research. “It is the only chance, other than going to Mars, to mimic movement of water as it would be on Mars,” he told TFK.

For years, NASA used zero-gravity flights to prepare and train astronauts. “I have not been to space,” Peters of Zero-G says, “But I have been told by astronauts that zero-gravity feels exactly the same.” As humans continue to explore the universe beyond Planet Earth, zero-gravity flights will remain an important and fun tool. “It never gets old,” Peters says “I would do it every weekend for the rest of my life if I could.”

1.Why do scientists set up man-made zero-gravity environment？

A.To study the water on the earth.

B.To offer weightlessness as a business.

C.To take scientists to any other planets.

D.To mimic the condition of space for experiments.

2.How much time of weightlessness can a Zero-G light offer？

A.About 30 seconds. B.About 90 seconds.

C.About 15 minutes. D.About 30 minutes.

3.What feature do the parabolas in Zero-G flights have？

A.The gentler parabolas are, the more satisfied the researchers are.

B.The steeper parabolas are, the less weight the passengers feel.

C.The steeper parabolas are, the more successful the experiments are.

D.The gentler parabolas are, the more quickly water on Mars flows.

4.What can be inferred about the Zero-G flight from the text？

A.It is useless for training astronauts.

B.It has no side effect on human body.

C.It creates a substitutable environment of zero gravity in space.

D.It is cheaper but more dangerous than space travel.
