SECTION B PASSAGES

Directions: In this section, you will hear several passages. Listen to the passages carefully and then answer the questions that follow.

听力原文: Soon it would be the holidays, but before that, there was the end of year exams. All the students had been working hard for some time. If they didn't pass, they would have to take them again in September. There were usually a few who failed, but Rosy was determined not to be one of them. She had worked hard all year, but just before the exams she was working so hard that her sister Betty was worried about her. She was staying up too late. The night before the first exam, Betty insisted that she should have an early night and take a sleeping pill. She promised to wake her in the morning.

As she was falling asleep, Rosy was worried that she might oversleep. Her mind kept jumping from subject to subject. At last, with the help of the pill, she fell asleep. In no time at all, she was sitting in the examination hall, looking at the paper. She couldn't answer any of the question. Everyone round her was writing pages and pages. However hard she thought, she couldn't find anything to write about. She kept looking at her watch. Time was running out. There was only an hour left. She started one question, wrote two sentences, gave up and tried another one. With only half an hour left she wrote another two sentences. By this time she was so worried that she started crying. Her whole body shook. It shook so much that it woke her up. She was still in bed and it had all been a terrible dream. A minute later, Betty called her name.

Why did Rosy study until very late at night?

A.She wanted to pass the exams.

B.She had not worked very much.

C.She wanted her sister to worry about her.

D.All the students were working hard.

The timing of flu season is a little hard to predict. Part of what makes it unpredictable
is that scientists still don t understand exactly why we have one at all. There have been lots of theories: One theory is that people spend more time indoors, with the windows closed, breathing each other s air. Other scientists have argued that cold of winter weakens our immune systems. A third theory is that the flu virus lives in the cold, dry air, but suffers in the warm, humid air. For a while, scientists had a hard time testing these theories: they needed to run experiments, but researchers aren t allowed to infect humans with illnesses, and most lab animals arent affected by the flu the same way people are. In 2007, a medical researcher named Peter Palese found an 80-year-old journal article that reported that guinea pigs (豚鼠)get infected and pass on the flu just like humans. Palese decided to test Theory 3. The research team led by Palese ran several experiments and in each experiment, they injected half the guinea pigs with influenza A (the common flu), and put them in a box next to a box of uninfected animals. At a temperature of 41 degrees, all four of the exposed guinea pigs caught the flu, but when Palese repeated the experiment at 68 degrees, only one of the animals was infected. And when he ran the test at 86 degrees, none of the exposed animals got sick. The researchers also ran experiments where they varied the humidity in the room but kept the temperature constant: the drier the air, they found, the more animals got sick. Palese s study showed that the influenza virus does spread more effectively in cold, dry air.

What does Paragraph 3 mainly discuss?

A.The direction for future research.

B.The necessity of running more tests.

C.The difficulty of testing the theories.

D.The cost of animal experiments.

The geology of the Earth's surface is dominated by the particular properties of water. Pre
sent on Earth in solid, liquid, and gaseous states, water is exceptionally reactive. It dissolves, transports, and precipitates many chemical compounds and is constantly modifying the face of the Earth.

Evaporated from the oceans, water vapor forms clouds, some of which are transported by wind over the continents. Condensation from the clouds provides the essential agent of continental erosion: rain. Precipitated onto the ground, the water trickles down to form. brooks, streams, and rivers, constituting what is called the hydrographic network. This immense polarized network channels the water toward a single receptacle: an ocean. Gravity dominates this entire step in the cycle because water tends to minimize its potential energy by running from high altitudes toward the reference point that is sea level.

The rate at which a molecule of water passes through the cycle is not random but is a measure of the relative size of the various reservoirs. If we define residence time as the average time for a water molecule to pass through one of the three reservoirs--atmosphere, continent, and ocean--we see that the times are very different. A water molecule stays, on an average, eleven days in the atmosphere, one hundred years on a continent and forty thousand years in the ocean. This last figure shows the importance of the ocean as the principal reservoir of the hydrosphere but also the rapidity of water transport on the continents.

A vast chemical separation process takes places during the flow of water over the continents. Soluble ions such as calcium, sodium, potassium, and some magnesium are dissolved and transported. Insoluble ions such as aluminum, iron, and silicon stay where they are and form. the thin, fertile skin of soil on which vegetation can grow. Sometimes soils are destroyed and transported mechanically during flooding. The erosion of the continents thus results from two closely linked and interdependent processes, chemical erosion and mechanical erosion. Their respective interactions and efficiency depend on different factors.

According to the passage, clouds are primarily formed by water ______.

A.precipitating onto the ground

B.changing from a solid to a liquid state

C.evaporating from the oceans

D.being carried by wind

Trouble in Paradise Valley

A On one side of the argument there are eagles, wolves and orchids; on the other side there are endless heavy lorries and burgeoning economic growth. Welcome to Europe's new environmental battleground The conflict is coming to a head for the first time in a pristine valley in north-east Poland, crammed with spectacular wildlife, which has been earmarked as the route for a badly-needed motorway to the Baltic states. The clash of priorities has bitterly divided public opinion in Poland itself and has now set the country on collision course with the European Union. Yet the struggle to save the Rospuda valley is only the first of many conflicts likely to arise between economic development in the new EU member nations of central and eastern Europe, and their wildlife heritage.

B Species which have long been rare or extinct in western European countries, such as lynx, elk, wolf and beaver, along with scores of uncommon bird species, from eagles to corncrakes, still have substantial populations in the ten central and eastern European nations which have recently joined the EU. In Poland and the other member states which joined in 2004 (the Creek Republic, Slovakia, Slovenia, Hungary and the three Baltic countries of Estonia, Latvia and Lithuania), as well as in Bulgaria and Romania, which joined this year, two remarkable habitats in particular act as giant wildlife reservoirs for Europe as a whole. One is the vast extent of ancient forests, some of which are still primeval—meaning they have never been cut down and replanted—and the other is the great range of wetlands in river valleys, flood plains and deltas.

C The Rospuda valley combines both. The Rospuda river flows through the ancient Augastow Forest near Poland's border with Lithuania, one of the mast pristine forest regions in all of Europe; and the river's course is bracketed by a peat bog wkieh is astonishingly rich in mammals, rare birds, plants and insects. In environmental terms, the valley is a jewel Yet it sits squarely astride the route for one of Europe's most ambitious road schemes, the so-called Vm Baltica expressway from Warsaw to Heisinki, which will pass through the Baltic states. The section of the new road which is intended to be the bypass for the small town of Augustow, where two routes from Warsaw join, is planned to go right through the valley's heart.

D Environmentalists contend that the road will irreparably damage the valley, and insist an alternative route, further to the west, must be used; the Polish government, riding a wave of new prosperity with annual economic growth running at six per cent, and desperate to upgrade its transport links with its neighbours as quickly as possible, insists that the Rospuda route is the right one, wildlife or no wildlife. The people of Augustow, who are sick of the unending procession of heavy lorries through their town, heartily agree.

E A survey carried out by the Polish Bird Protection Society, Otop, has found that within 750 metres each side of the centreline of the proposed expressway as it passes through the valley, no fewer than 20 species of birds are breeding which are specifically protected, as rare or threatened, under European law. They represent a British birdwatcher's dream, ranging from the white-tailed, short-toed and lesser-spotted eagles, through the black grouse and the capercaillie, to the corncrake, the crane and the great snipe. There is much more. Among a profusion of rare wildflowers, there are 20 orchid species in the valley, including the last colony in Poland of the musk orchid Herminium monorchls, and mammals which are resident or pass through the forest and the marsh include lynx, wolf, elk, wild boar, otter and beaver.

F The Polish centre-left national daily newspaper, Gazeta Wyborcza, has taken up the cause of saving Rospuda, and has given away green lapel ribbons for supporters to wear. An electronic peti

第10题
When Julius Caesar made his triumphal entrance into Rome in 45 BC, he celebrated by giving
a feast at which thousands of guests ate gorged (狼吞虎咽) poultry, seafood and game. Similar celebrations featuring excessive consumption of animal flesh have marked human victories-in war, sport, politics and commerce-since our species learned to control fire. Throughout the developing world today, one of the first things people do as they climb out of poverty is to shift from their peasant diet of mainly grains and beans to one that is rich in pork or beef. Since 1950, per capita consumption of meat around the globe has more doubled.

Meat, it seems, is not just food but reward as well. But in the coming century, that will change. Much as we have awakened to the full economic and social costs of cigarettes, we will find we can no longer subsidize (补助) or ignore the costs of mass-producing cattle, poultry,, pigs, sheep and fish to feed our growing population. These costs include hugely inefficient use of fresh water and land, heavy pollution from livestock feces, rising rates of heart disease and other degenerative illness, and spreading destruction of the forests on which much of our planet's life depends.

First, consider the impact on supplies of fresh water. To produce l kg of feedlot beef requires 7kg of feed grain, which takes 1 000kg of water to grow. Pass up one hamburger, and you'll save as much as water as you save by taking 40 showers with a low-now nozzle (喷嘴). Yet in the U. S. , 70% of all the wheat, corn and other grain produced go to feeding herds of livestock. Around the world, as more water is diverted to raising pigs and chickens instead of producing crops' for direct consumption, millions of wells are going dry, India, China, North Africa and the U. S. are all running freshwater deficits, pumping more from their .aquifers (蓄水层) than rain can replenish. As populations in water scarce regions continue to expand, governments will inevitably act to cut these deficits by shining water to grow food, not feed. The new policies will raise the price of meat to levels unaffordable for any but the rich.

That prospect will doubtlessly provoke protests that direct consumption of grain can't provide the same protein that meat provides. Indeed, it can't. But nutritionists will attest that most people in the richest countries don't need nearly as much protein as we are currently getting from meat, and there are plenty of vegetable sources--including the grains now wasted on feed--that can provide the protein we need.

In the opening paragraph, the author introduces his topic by ______.

A.justifying an assumption

B.giving an example

C.making a comparison

D.explaining a phenomenon
