American researchers found females are the more talkative sex because of a special “language protein(蛋白质)” 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 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 vocalcalls 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 of the neurobiological basis of sex differences in vocal communication in mammals. “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 |

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 |
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 |
Yawning sends out certain messages -either “Oh ，this movie is so boring” or “I probably need to get some sleep”. But did you know that a yawn can also help your brain to cool down when it is overheated?
A new study, led by a research team at Princeton University, has indicated that yawning could be the brain’s natural way of regulating temperature. People yawn more often when the temperature outdoors is lower than their body temperature but are less likely to yawn when it is hotter outdoors, according to Sciencedaily. com.
The research team did an experiment on 160 people, 80 in summer and 80 in winter, to examine how often they yawned at different air temperatures. The study found that people yawned more often in winter than in summer. Scientists say that when the air temperature is lower outside the body, there is heat exchange between the overheated brain and the cool air. But when the air temperature is higher than or equal to the body, people are less likely to yawn because the hot air they breathe in will make the brain even hotter.
When people yawn, their jaw is also stretched ，which increases blood flow and may also help cool the brain
The study showed that the amount someone yawned could be related to the amount of time they spent outside. The longer they spent outside in summer, the less they yawned. Nearly 40 percent of participants yawned within their first five minutes outside, but after that the percentage was reduced to less than 10 percent.
However, the result was the opposite in winter. The number of people who yawned increased when they spent more than five minutes outdoors. But the change was only slight compared to summertime.
According to Gallup, this is the first report to show that yawning frequencies change depending on season. This could help us to understand better the way our brains work. It may also help us understand the reason why frequent yawning can sometimes be a sign of brain disease.The purpose of the experiment is ______.
| A． to prove people yawn in winter and in summer equally |
| B． to indicate brain can regulate temperature naturally |
| C． to find the frequency of people’s yawning |
| D． to show the real reason why people yawn |
The information we get from Paragraphs 5 and 6 is that ______.
| A． longer outdoor summertime results in more yawns |
| B． yawning frequency changes with outdoor time |
| C． yawning frequency increases with outdoor time |
| D． longer outdoor wintertime leads to fewer yawns |

Some young Cambodians are learning a new sport — skateboarding. The country’s first skateboard park is located on the grounds of a local charity group at the edge of Phnom Penh, the capital.
Sports like Khmer boxing and soccer are wildly popular in Cambodia. But Chea ，who has been skating for 6 months ，says skating has already become his favorite sport.
The skaters are learning tricks like launching off a jump or half-pipe and flying through the air on their narrow wooden boards.
A non-governmental organization called Skateistan Cambodia organizes weekly programs at the park. Skateistan started its work in Afghanistan years ago. Rory Burke is working with the group which expanded to Cambodia last year.
Rory Burke points out, “Yeah, it’s definitely not a typical Cambodian pastime (消遣）.And I think the idea of ‘why skateboarding’is that it’s not been done before here. We want to use skateboarding as something saying, ‘Hey，this is new ，this is something different.，And that kind of itself becomes a little bit of hook. People see it and they think and they say, ‘Wow, what is that?，and they want to get involved. ”
Skateistan partners with local groups that work with young people. The park is on the grounds of the group known as PSE, where children attend school and learn a trade. There are almost one hundred twenty participants. They all come from troubled lives.
Seventeen-year-old Sang Rotha is a student at PSE. “Sometimes I don’t do well on subjects like math,”he says, “I feel bad when I find it hard to keep up with my lessons. So that is why I skateboard -to improve my bad feelings. ’，
He says he began skateboarding more than a year ago. Before he started training, it seemed very easy. But it was very difficult to learn tricks, and he got hurt a lot from falling off.
Rory Burke says learning to deal with the difficulties is part of the lesson for these young skateboarders.According to the passage, PSE is a group ______.

| A． a sport liked by most young Cambodians |
| B． an increasingly popular sport in Cambodia |
| C． a sport used to better young Cambodians’ life |
| D． a good way to train young Cambodians’ learning skills |
People think what I do is so wonderful because I interview stars. And I have to admit that when I first started working at Sassy in 1987 I was excited about that part of my job for the first couple of months，anyway. Then I noticed how stars would fool me around for months. I could never get enough time with a star to find out anything interesting, and some acted just simply rudely. I started hating the way I was treated, and I was really disappointed to see that these people I had worshipped (崇拜）before were pretty ordinary. So I decided I would just tell the truth instead of keeping up their myths(神秘）.If the star was a bad guy, I would say so. If I thought anyone was stupid, I did not hold back that information.
I thought readers would appreciate that kind of honesty. Surprisingly, many of them hated me for it. I have gotten so many attacks on my character. In their eyes，being famous is everything, even more desirable than being truly creative and talented
Why do we need stars? In fact, the media created stars to satisfy our basic need for gossip (闲话）.Over time, talking about people we have never met and we are never likely to meet has become what we are crazy about. Thus, some people are more interested in the personal lives of the stars than in the lives of their own family and their own friends. That is why it is so ridiculous when a star wants to discuss only his or her work in an interview -as we care. We want the dirt on their personal lives.
There is another reason we worship stars. As a whole, our society is not as religious as it once was. It seems that people need something to fulfill them the way religion once did. Star worship exists as an unfulfilling desire for true heroes.
We make them stars, but then their reputation makes us feel unimportant, and we truly feel better about ourselves when they die. I am part of this whole process. No wonder I feel soiled at the end of workday.What are the stars like according to the author?
| A． They always treat others rudely. |
| B． They always talk about something dull. |
| C． They are acutually ordinary people. |
| D． They are usually honest and polite, |
We worship stars because ______.
A, we need true mental heroes to support us
B. we can learn something useful from famous stars
C. we concern about the stars ，family and friends
D. we like talking about the stars ，dressing stylesWhen the author is writing this article ，his tone sounds ______.
A, excited B. angry C. worried D. calmWhat is the main purpose of the author writing the passage?
| A． To show the disadvantages of working with stars. |
| B． To remind us not to worship famous stars blindly. |
| C． To laugh at the failures of stars he has interviewed. |
| D． To talk about the reasons why we worship stars. |
A father in Wuhan, nicknamed "Eagle Dad" for his controversial parenting style, has dismissed critics' claims that he pushes his 4-year-old son too hard.
Police officer Wang Shaoyan came under the spotlight this month after his child took part in an 18-kilometer race in the Hubei provincial capital.
Some parents attacked his methods of extreme physical training, while others reacted strongly to his admission that he regularly exposes the youngster to cold showers. "I just want my son to reach his full potential," Wang said, adding that 4-year-old son not only runs 3 km every day he also takes cold showers from time to time to strengthen his body's resistance and willpower.
"He has never taken any sick leave from kindergarten," he said proudly. However, some parents find his methods too extreme.
"I'm not sure a 4-year-old is prepared for such intense training," said Zhang Ruxia a woman who gave birth to two boys in October in Tianjin. "You can have good intentions to train your child at an early age but you also have to consider whether he can take it." Wang responded by saying children are too young to make decisions, and it is up to parents to lead them on the right path.
"I read many materials before and the whole process is step-by-step without pushing or imposing on my son," Wang said. The father said he was not acting rashly but following a scientific way of education. He said the doubts about his methods reflect the declining standards of modern education.
"Many people in Japan give their children cold showers too ,and no one is fussing about it，" he said. The traditional way of education applied by most of his peers might not necessarily help bring the best out of a child he said.
Wang said in addition to the physical training, he has also laid out a detailed and particular program to strengthen the intelligence of the child. "I have hired some university students to expand his knowledge in natural sciences, while playing the video for English-language teaching as well," he said.For what reason was Wang made known to the public?
| A．He employed some college students to teach his son. |
| B．He made his kid take a long distance race. |
| C．He exposed his 4-year-old to cold showers. |
| D．He forced his youngster to run 3 km every day. |
Which statement is supported by the parents who hold the opposite opinion?
| A．Extreme physical training can explore children's full potentials. |
| B．Taking cold showers regularly is beneficial for children's development. |
| C．It's up to parents to lead children on the right path. |
| D．The way to educate children should agree with their age. |
What does the phrase "fussing about” probably mean in the 8th paragraph?
| A．Minding about. | B．Paying attention to. |
| C．Laughing at. | D．Talking about. |
In Eagle Dad’s opinion, his extreme parenting was questioned because____.
| A．he didn’t take it step by step in a scientific way |
| B．the highly tense work-out was misunderstood |
| C．modern education is not challenging enough |
| D．some parents were jealous of his success |
