American researchers found females are the more talkative sex because of a special “language protein” in the brain.

The study, conducted by neuroscientists(神经学家) 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(超声波的) 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.”

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?

I wondered what I would do if ________ with a real mid-air medical emergency --- without access ________ a hospital staff and the usual emergency equipment. So ________ the New England Journal of Medicine last week________a study about in-flight medical events, I read it with ________.

The study estimated that there are a(n) ________of thirty in-flight medical emergencies on U.S. flights every day.

Let’s face it: plane rides are ________. For starters, cabin pressures at high altitudes are set at roughly ________they would be if you lived at 5,000 to 8,000 feet above sea level. Most people can tolerate these pressures pretty ________, but passengers with heart disease ________experience chest pains as a result of the reduced amount of oxygen flowing through their blood. ________ common in-flight problem is deep venous thrombosis(静脉血栓) --- the so-called economy class syndrome. ________ happens, don’t panic. Things are getting better on the in-flight-emergency front. Thanks to more recent laws, flights with at ________one attendant are starting to install(安装) emergency medical equipment to treat heart attacks.

Why do Americans struggle with watching their weight, while the French, who consume rich food, continue to stay thin? Now a research by Cornell University suggests how life style and decisions about eating may affect weight. Researchers conclude that the French tend (易于) to stop eating when they feel full. However, Americans tend to stop when their plate is empty or their favorite TV show is over.

According to Dr. Joseph Mercola, a health expert, the French see eating as an important part of their life style. They enjoy food and therefore spend a fairly long time at the table, while Americans see eating as something to be squeezed (挤出) between the other daily activities. Mercola believes Americans lose the ability to sense when they are actually full. So they keep eating long after the French would have stopped. In addition, he points out that Americans drive to huge supermarkets to buy canned and frozen foods for the week. The French, instead, tend to shop daily, walking to small shops and farmers’ markets where they have a choice of fresh fruits, vegetables, and eggs as well as high-quality meats for each meal.

After a visit to the United States, Mireille Guiliano, author of French Women Don’t Get Fat, decided to write about the importance of knowing when to stop rather than suggesting how to avoid food. Today she continues to stay slim and rarely goes to the gym.

In spite of all these differences, evidence shows that recent life style changes may be affecting French eating habits. Today the rate of obesity - or extreme overweight - among adults is only 6%. However, as American fast food gains acceptance and the young reject (拒绝) older traditions, the obesity rate among French children has reached 17% - and is growing.

1.In what way are the French different from Americans according to Dr. Joseph Mercola?

A. They go shopping at supermarkets more frequently.

B. They regard eating as a key part of their life style.

C. They squeeze eating between the other daily activities.

D. They usually eat too much canned and frozen food.

2.This text is mainly about the relationship between ______.

A. children and adults B. Americans and the French

C. life style and obesity D. fast food and overweight

3.Where does this text probably come from?

A. A health report B. A book review

C. A TV interview D. A food advertisement
