American researchers found females are the more talkative sex because of a special “l(fā)anguage protein” in the brain.
The study, conducted by neuroscientists(神經(jīng)學(xué)家) and psychologist from the University of Maryland, concluded that women talked more because they had more of the Foxp2 protein.The research, published in the Journal of Neuroscience, found that higher levels were found among humans that were women but in rats that were males.Their findings came after it was previously claimed that ladies speak about 20,000 words a day – over 13,000 more than men.“This study is one of the first to report a sex difference in the expression of a language-associated protein in humans or animals,” said Prof Margaret McCarthy, who led the study.In their study, the researchers attempted to determine what might make male rats more vocal than their female friends.
They separated four-day-old rats from their mothers and then counted the number of times they cried out in the “ultrasonic(超聲波的) range”, the frequencies higher than humans can hear, over five minutes.While both sexes called out hundreds of cries, the males called out twice as often, they found.But when the pups were returned to their mother’s cage, she fussed over her sons first.Tests conducted on the parts of the brain known to be associated with vocal calls showed the male pups have up to twice as much Foxp2 protein as the females.The researchers then increased the production in the brains of female pups and reduced it in males.This led to the female rats crying out more often and their mothers showing more interest to them.In contrast, males became less “talkative”.
The researchers then tested samples from ten children, aged between three and five, which showed that females had up to 30 per cent more of the Foxp2 protein than males, in a brain area key to language in humans.
“Based on our observations, we assume higher levels of Foxp2 in girls and higher levels of Foxp2 in male rats is an indication that Foxp2 protein levels are associated with the more communicative sex,” said Prof McCarthy.
“Our results imply Foxp2 as a component (成分)of the neurobiological basis of sex differences in vocal communication in mammals.”
1.From the second paragraph, we can learn that ________.
A.women always speak more words than men
B.men and male rats have low levels of language protein
C.women and male rats have similar levels of Foxp2
D.McCarthy isn’t the first to find females more talkative
2.The underlined phrase “fussed over” in the third paragraph probably means______.
A.paid attention to
B.related to
C.put pressure on
D.counted on
3.The researchers carried out the experiments on rats in order to _______.
A.test which part of the brain is key to language in rats and humans
B.prove the levels of Foxp2 protein in humans and rats are different
C.determine the reason why female rats are more talkative than male rats
D.discover the association between Foxp2 protein and vocal communication
4.Which of the following can be the best title for the passage?
A.Tests on humans and rats
B.Why women are the talkative sex
C.Sex differences in Foxp2 protein
D.Foxp2 protein determines oral ability

Dyslexia is a learning disorder, it interferes with the ability to recognize words, and for some readers to understand what they have read. Experts say dyslexia affects about five to ten percent of the population of the United States. Researchers have long known that people with dyslexia write or read words and letters backwards in the wrong order.
But a new study shows that people with dyslexia may have trouble redirecting their attention between senses, from seeing something to hearing something. The study suggests something that might help dyslexic people learn more quickly - play video games.
Vanessa Harrar of Britain’s University of Oxford led the study. She reported the findings in the journalCurrent Biology. The study suggests that dyslexic people may have trouble moving quickly from what they read to what they hear.
In the study, Doctor Harrar tested 17 people with dyslexia, and 19 others without reading problems. The volunteers were asked to push a button as quickly as possible when they heard a sound, saw a light or experienced both together. Doctor Harrar compared the speed of their reactions. She found that people with dyslexia were just as fast as the others when they saw only a picture or heard only a sound. But the Dyslexicshad a slower reaction time when they heard a sound and saw a picture at the same time, this may have an effect on how dyslexic children are taught how to read.
Doctor Harrar feels like playing video games could help dyslexic people shift from seeing to hearing more quickly. She adds that images in video games force the eyes to move and focus quickly. “Video game types of things pop out of here and there, they move your eyes around the screen quite quickly in response to things quite quickly, and the more you play a video game the faster you get that kind of thing. So, the video game is really training the attention system to move quickly,” said Harrar. When children learn the alphabet, they usually see the letter first and then hear the sound, or they see and hear the letter at the same time. The study shows that Dyslexics might learn more quickly if they hear the sound of a letter or word first before seeing it.
1.According to Doctor Harrar’s study, the dyslexic people have difficulty in______.
A. recognizing words
B. reading words backwards
C. writing letters in order
D. shifting from seeing to hearing
2.Which factor affects the way dyslexic children are taught to read?
A. They react more slowly to a single picture or sound
B. They react as fast as others to a single picture or sound
C. It takes them longer to react to sounds and pictures together
D. It is difficult for them to understand before seeing the word
3.How does the author suggest Dyslexics are taught based on the research finding?
A. by putting hearing previous to seeing
B. by training the attention on games
C. by seeing first and then hearing later
D. by moving the eyes around the screen
4.What can be the best title of the passage?
A. Video Games Might Help Dyslexics
B. Dyslexia Affects Attention between Senses
C. Video Games Can Train the Attention System
D. Dyslexics Might Learn Better through Sound

According to the US government, wind farms off the Pacific coast could produce 900 gigawatts of electricity every year.Unfortunately, the water there is far too deep for even the tallest windmills to touch bottom.An experiment under way off the coast of Norway, however, could help put them anywhere.
The project, called Hywind, is the world’s first large-scale deepwater wind turbine (渦輪發(fā)電機(jī)).Although it uses a fairly standard 152-ton, 2.3-megawatt turbine, Hywind represents totally new technology.The turbine will be fixed 213 feet above the water on a floating spar, a technology Hywind’s creator, the Norwegian company StatoilHydro, has developed recently.The steel spar, which is filled with stones and goes 328 feet below the sea surface, will be tied to the ocean floor by three cables ; these will keep the spar stable and prevent the turbine from moving up and down in the waves.Hywind’s stability in the cold and rough sea would prove that even the deepest corners of the ocean are suitable for wind power.If all goes according to the plan, the turbine will start producing electricity six miles off the coast of southwestern Norway as early as September.
To produce electricity on a large scale, a commercial wind farm will have to use bigger turbines than Hywind does, but it’s difficult enough to balance such a large turbine so high on a floating spar in the middle of the ocean.To make that turbine heavier, the whole spar’s center of gravity must be moved much closer to the ocean’s surface.To do that, the company plans to design a new kind of wind turbine, one whose gearbox (變速箱) sits at sea level rather than behind the blades.
Hywind is a test run, but the benefits for perfecting floating wind-farm technology could be extremely large.Out at sea, the wind is often stronger and steadier than close to shore, where all existing offshore windmills are planted.Deep-sea farms are invisible from land, which helps overcome the windmill-as-eyesore objection.If the technology catches on, it will open up vast areas of the planet’s surface to one of the best low-carbon power sources available.
1.The Hywind project uses totally new technology to ensure the stability of_________.
A.the cables which tie the spar to the ocean floor
B.the spar which is floating in deep-sea water
C.the blades driven by strong and steady sea wind
D.the stones filled in the spar below the sea surface
2.To balance a bigger turbine high on a floating spar, a new type of turbine is to be designed with its gearbox sitting_________.
A.on the sea floor
B.on the spar top
C.a(chǎn)t sea level
D.behind the blades
3.Wide applications of deepwater wind power technology can_________.
A.solve the technical problems of deepwater windmills
B.make financial profits by producing more turbines
C.settle the arguments about environmental problems
D.explore low-carbon power resources available at sea

“Old wives tales” are beliefs passed down from one generation to another, For example, most of us remember our parents’ telling us to eat more of certain foods or not to do certain things.Is there any truth in these teachings? Some of them agree with present medical thinking, but others have not passed the test of time.
Did your mother ever tell you to eat your carrots because they are good for your eyes? Scientists now report that eating carrots can help prevent a serious eye disease called macular degeneration.Eating just one carrot a day can reduce the possibility of getting this disease by 40%.Garlic is good for you, too.It can kill the type of virus that causes colds.
