Easy Learning
Students should be jealous. Not only do babies get to doze their days away, but they’ve also mastered the fine art of learning in their sleep.
By the time babies are a year old they can recognise a lot of sounds and even simple words. Marie Cheour at the University of Turku in Finland suspected that they might progress this fast because they learn language while they sleep as well as when they are awake.
To test the theory, Cheour and her colleagues studied 45 newborn babies in the first few days of their lives. They exposed all the infants to an hour of Finnish vowel sounds—one that sounds like “oo”, another like “ee” and a third boundary vowel peculiar to Finnish and similar languages that sounds like something in between. EEG recordings of the infants brains before and after the session showed that the newborns could not distinguish the sounds.
Fifteen of the babies then went back with their mothers, while the rest were split into two sleep-study groups. One group was exposed throughout their night-time sleeping hours to the same three vowels, while the others listened to other, easier-to-distinguish vowel sounds.
When tested in the morning, and again in the evening, the babies who’d heard the tricky boundary vowel all night showed brainwave activity indicating that they could now recognise this new sound. They could identify the sound even when its pitch was changed, while none of the other babies could pick up the boundary vowel at all.
Cheour doesn’t know how babies accomplish this night-time learning, but she suspects that the special ability might indicate that unlike adults, babies don’t “turn off” their cerebral cortex while they sleep. The skill probably fades in the course of the first year of life, she adds—so forget the idea that you can pick up tricky French vowels as an adult just by slipping a language tape under your pillow. But while it may not help grown-ups, Cheour is hoping to use the sleeping hours to give remedial help to babies who are genetically at risk of language disorders.

16. Babies can learn language even in their sleep.
A. Right B. Wrong C. Not mentioned
17. An infant can recognize a lot of vowels by the time he or she is a year old.
A. Right B. Wrong C. Not mentioned
18. Finnish vowels are easy to distinguish.
A. Right B. Wrong C. Not mentioned
19. The three vowels mentioned in this article are all Finnish sounds.
A. Right B. Wrong C. Not mentioned
20. The study shows that the infant’s cerebral cortex is working while he is asleep.
A. Right B. Wrong C. Not mentioned
21. If an adult wants to learn a language faster. he can put a language tape under his pillow.
A. Right B. Wrong C. Not mentioned
22. Cheour’s finding is worthless.
A. Right B. Wrong C. Not mentioned

Screen Test
Every year millions of women are screened with X-rays to pick up signs of breast cancer. If this happens early ecough, the disease can often be treated successfully. According to a survey published last year, 21 countries have screening programmes. Nine of them, including Australia, Canada, the US and Spain, screen women under 50.
But the medical benefit of screening these younger women are controversial, partly because the radiation brings a small risk of inducing cancer. Also, younger women must be given higher doses of X-rays because their breast tissue is denser.
Researchers at the Polytechnic University of Valencia analysed the effect of screening more than 160,000 women at 11 local clinics. After estimating the women’s cumulative dose of radiation, they used two models to calculate the number of extra cancers this would cause.
The mathematical model recommended by Britain’s National Radiological Protection Board (NRPB) predicted that the screening programme would cause 36 cancers per 100,000 women, 18 of them fatal. The model preferred by the UN Scientific Committee on the Effects of Atomic Radiation led, to a lower figure of 20 cancers.
The researchers argue that the level of radiation-induced cancers is “not very significant” compared to the far larger number of cancers that are discovered and treated. The Valencia programme, they say, detects between 300 and 450 cases of breast cancer in every 100,000 women screened.
But they point out that the risk of women contracting cancer from radiation could be reduced by between 40 and 80 percent if screening began at 50 instead of 45, because they would be exposed to less radiation. The results of their study, they suggest, could help “optimise the technique” for breast cancer screening.
“There is a trade-off between the diagnostic benefits of breast screening and its risks.” admits Michael Clark of the NRPB. But he warns that the study should be interpreted with caution. “On the basis of the current data, for every 10 cancers successfully detected and prevented there is a risk of causing one later in life. That’s why radiation exposure should be minimised in any screening programme.”

第4部分：阅读理解(第31～45题，每题3分，共45分)
下面有3篇短文，每篇短文后有5道题。请根据短文内容，为每题确定1个最佳选项。

第一篇
Powering a City? It’s a Breeze.
The graceful wooden windmills that have broken up the flat Dutch landscape for centuries — a national symbol like wooden shoes and tulips — yielded long ago to ungainly metal-pole turbines.
Now, windmills are breaking into a new frontier. Though still in its teething stages, the “urban turbine” is a high-tech windmill designed to generate energy from the rooftops of busy cities. Lighter, quieter, and often more efficient than rural counterparts, they take advantage of the extreme turbulence and rapid shifts in direction that characterize urban wind patterns.
Prototypes have been successfully tested in several Dutch cities, and the city government in the Hague has recently agreed to begin a large-scale deployment in . Current models cost US $8, 000 to US $12, 000 and can generate between 3, 000 and 7, 000 kilowatt hours of electricity per year. A typical Dutch household uses 3,500 kilowatt hours per year, while in the United States, this figure jumps to around 10, 000 kilowatt hours.
But so far, they are being designed more for public or commercial buildings than for private homes. The smallest of the current models weigh roughly 200 kilograms and can be installed on a roof in a few hours without using a crane.
Germany, Finland and Denmark have also been experimenting with the technology, but the ever-practical Dutch are natural pioneers in urban wind power mainly because of the lack of space. The Netherlands, with 16 million people crowded into a country twice the size of Slovenia, is the most densely populated in Europe.
Problems remain, however, for example, public safety concerns, and so strict standards should be applied to any potential manufacturer. Vibrations are the main problem in skyscraper-high turbine. People don’t know what it would be like to work there, in an office next to one of the big turbines. It might be too hectic.
Meanwhile, projects are under way to use minimills to generate power for lifeboats, streetlights, and portable generators. “I think the thing about wind power is that you can use it in a whole range of situations,” said Corin Millais, of the European Wind Energy Association. “It’s a very local technology, and you can use it right in your backyard, I don’t think anybody wants a nuclear power plant in their backyard.”

31. What are the symbols of the Netherlands according to the first paragraph?
A. The flat landscape.
B. Wooden shoes and wooden windmills.
C. Metal-pole turbines.
D. Both A and B.
32. Which statement best describes the urban turbine mentioned in the second paragraph?

D. It is driven by urban wind.
33. The smallest models of an urban turbine
A. is designed for private homes.
B. weighs 2,000 kilograms.
C. can be carried up to the rooftop without a crane.
D. can he installed with a crane.
34. Netherlands leads in the urban turbine technology because
A. the Dutch are natural pioneers.
B. the Dutch have a tradition with windmills.
C. the Netherlands is windier than Germany, Finland and Slovenia.
D. the Netherlands is a small country with a large population.
35. According to the last paragraph, what are the advantages of wind power technology?
A. It can be used for different purposes.
B. It can replace nuclear power plant.
C. It can be installed in one’s backyard.
D. Both A and C.

Explorer of the Extreme Deep
　　Oceans cover more than two-thirds of our planet. Yet, just a small fraction of the underwater world has been unexplored. Now, Scientists at the Woods Hole Oceanographic Institution (WHOI) in Massachusetts are building an underwater vehicle that will carry explorers as deep as 6, 500 meters (21, 320 feet). The new machine, known as a manned submersible (能潜水的) or human-operated vehicle (HOV), will replace another one named Alvin which bas an amazing record of discovery, playing a key role in various important and famous undersea expeditions. Alvin has been operating for 40 years but can go down only 4, 500 meters (14, 784 feet). It’s about time for an upgrade, WHOI researchers say.
　　Alvin was launched (发动) in 1964. Since then, Alvin has worked between 200 and 250 days a year, says Daniel Fornari, a marine geologist (地质学者) and director of the Deep Ocean Exploration Institute at WHOI. During its lifetime，Alvin has carried some 12, 000 people on a total of more than 3, 000 dives. A newer, better versions of Alvin is bound to reveal even more surprises about a world that is still full of mysteries, Fornari says. It might also make the job of exploration a little easier. “We take so much for granted on land,” Fornari says. “We can walk around and see with our eyes how big things are. We can see colors，special arrangements.”
　　Size-wise, the new HOV will be similar to Alvin. It’ll be about 37 feet long. The setting area inside will be a small sphere，about 8 feet wide，like Alvin，it’ll carry a pilot and two passengers. It will be just as maneuverable (机动的). In most other ways, it will give passengers more opportunities to enjoy the view, for one thing. Alvin has only three windows, the new vehicle will have five, with more overlap so that the passengers and the pilot can see the same thing.
　　Alvin can go up and down at a rate of 30 meters every second, and its maximum speed is 2 knots (about 2.3 miles per hour), while the new vehicle will be able to ascend and descend at 44 meters per second. It’ll reach speeds of 3 knots, or 3.5 miles per hour.

36. What is Alvin?
A. A research institute.
B. A transporting vehicle.
C. A submersible.
D. A scientist.
37. Which of the following statements is NOT a fact about Alvin?
A. It can carry explorers as deep as 6, 500 meters.
B. It has played a key role in various important undersea expeditions.
C. It was launched in the sixties of the twentieth century.
D. It has been used for more than 40 years.
38. “... a world that is still full of mysteries” refers to
A. the earth.
B. out space.
C. the ocean.
D. Mars.
39. In what aspects are the new HOV and Alvin similar?
A. Size.
B. Speed.
C. Capacity.
D. Shape.
40. In what aspects are the new HOV and Alvin different?
A. Offering better views.
B. Speed.
C. Size.
D. Both A and B.
