Recently we told you about a finding that more years of school could help students get higherscores on intelligence tests.That was the finding of a study of teenage males in Norway.Now,other research shows that physical activity may help students do better in their classes .
The research comes as educators in some countries are reducing time for activities like physical education.They are using the time instead for academic subjects like maths and reading.The studies appeared between 2007 and 2013.They included more than 55,000 children,aged 6 to 18.
Amika Singh:“Based on the results of our study,we can conclude that being physically active is beneficial for academic performance. There are,first,Physiological explanations,like more blood flow, and so more oxygen to the brain.Being physically active means there are more hormones(荷爾蒙)produced like endorphins(內啡肽).And endorphins make your stress level lower and  your mood improved, which means you also perform better.”
Also,students involved in organized sports learn rules and how to follow them.This could improve their classroom behavior and help them keep their mind on their work.
The study leaves some questions unanswered,however.Ms.Stash says it is not possible to say whether the amount or kind of activity affected the level of academic improvement.This is because of differences among the studies .
Also.they were mostly observational studies.An observational study is where researchers do not do controlled comparisons.They only describe what they observe.So they might observe a link that students who are more active often have better grades.But that does not necessarily mean being active was the cause of those higher grades.
The researchers said they found only two high - quality studies.They called for more high-
quality studies to confirm their findings.They also pointed out that “outcomes for other parts of the world may be quite different. ”
Still,the general finding was that physically active kids are more likely to do better in school.Ms.Singh says schools should consider that finding before they cut physical education programs.Her paper on “Physical Activity and Performance at School”is published in the Archives of Pediatric and Adolescent Medicine.
【小題1】The passage mainly tells us that ____

A.a research on physical education has been done by the researchers
B.there exists a possibility that physical activity leads to higher grades
C.the amount or kind of activity directly affects academic level
D.the research shows that the children aged 6 to 1 8 don't do sports
【小題2】Which of the following is TRUE?
A.Being mentally active is good for academic subjects.
B.The more hormones you have,the more stressed you will get.
C.They have found many high-quality studies to prove the research.
D.The educators in the research think studies,not exercise,mean much to students.
【小題3】The underlined sentence in Paragraph 7 probably means ____.
A.good marks result from high-quality study
B.findings probably vary in different areas
C.physical activity will spread all over the world
D.academic performance depends on the surroundings
【小題4】What's the purpose of writing the passage?

      People from East Asia tend to have more difficulty than those from Europe in distinguishing facial expressions — and a new report published online in Current Biology explains why.
Rachael Jack, University of Glasgow researcher, said that rather than scanning evenly(均勻的) across a face as Westerners do, Easterners fix their attention on the eyes.
"We show that Easterners and Westerners look at different face features to read facial expressions," Jack said. "Westerners look at the eyes and the mouth in equal measure, whereas Easterners favor the eyes and neglect (忽略) the mouth."
According to Jack and her colleagues, the discovery shows that human communication of emotion is more complex than previously believed. As a result, facial expressions that had been considered universally recognizable cannot be used to reliably convey emotion in cross-cultural situations.
The researchers studied cultural differences in the recognition of facial expressions by recording the eye movements of 13 Western Caucasian and 13 East Asian people while they observed pictures of. expressive faces and put them into categories: happy, sad, surprised, fearful, disgusted, angry, or neutral. They compared how accurately participants read those facial expressions using their particular eye movement strategies.
It turned out that Easterners focused much greater attention on the eyes and made significantly more errors than did Westerners. "The cultural difference in eye movements that they show is probably a reflection of cultural difference in facial expressions," Jack said. "Our data suggest that whereas Westerners use the whole face to convey emotion, Easterners use the eyes more and mouth less."
In short, the data show that facial expressions are not universal signals of human emotion. From here on, examining how cultural factors have diversified these basic social skills will help our understanding of human emotion. Otherwise, when it comes to communicating emotions across cultures, Easterners and Westerners will find themselves lost in translation.
【小題1】 The discovery shows that Westerners         .

A.pay equal attention to the eyes and the mouth 
B.consider facial expressions universally reliable

A.To make a face at each other. B.To get their faces impressive. 
C.To classify some face pictures. D.To observe the researchers' faces. 
【小題3】 What does the underlined word "they" in Paragraph 6 refer to?
A.The participants in the study. 
B.The researchers of the study. 
C.The errors made during the study. 
D.The data collected from the study.  
【小題4】 In comparison with Westerners, Easterners are likely to         .
A.do translation more successfully 
B.study the mouth more frequently 
C.examine the eyes more attentively 
D.read facial expressions more correctly 
【小題5】 What can be the best title for the passage?
A.The Eye as the Window to the Soul

Many people believe that teaching children music makes them smarter, better able to learn new things. But the organizers of a new study say there's no scientific evidence that early musical training affects the intelligence of young people.
An estimated 80 percent of American adults think music lessons improve children's abilily to learn or their performance in school. They say that the satisfaction for learning to play a new song helps a child express creativity.
Researchers at Harvard University, however, have found that there's one thing musi­cal training does not do. They say it does not make children more intelligent. Samuel Mehr is a graduate student at Harvard's School of Education. He said it is wrong to think that learning to play a musical instrument improves a child's intellectual development. He says the evidence comes from studies that measured the mental ability of two groups of 4-year-olds and their parents. One group attended music class, the other went to a class that places importance on the visual arts—arts that can be seen.
"The evidence there is 'no'. We found no evidence for any advantage on any of these tests for the kids participating in these music clases," said Mehr.Samuel Mehr says researchers have carried out many studies in an effort to learn whether musical training can make children smarter. He says the results have been mixed. He says only one study seems to show a small percentage increase in IQ, intellectual scores among students after one year of music lessons. He does not believe that IQ is a good measure of child's intelligence. He says researchers in his study compared how well children in the musical training group did on mental processing tasks or projects, then the results were compared to those of children who did not take lessons. There was no evidence that the musical training group did much better on the mental tasks than the other group.
The researchers comfirmed the results with a larger group of children and their par­ents.Mr Mehr says music lessons may not offer children a fast easy way to gain entry to the best schools later of their life. But he says the training is still important for cultural reasons. In his words, "We teach music because music is important for us."
【小題1】According to the new study, musical training______.

A.makes children smarter
B.helps a child express creativity
C.does not make children more intelligent
D.improve children's ability to learn in school
【小題2】Samuel Mehr may agree that______.
A.the children who attended music class are smarter than those who attended arts class
B.IQ is a good measure of a child's intelligence
C.we needn't to teach children music
D.music training is still important for cultural reasons
【小題3】In order to confirm his view, Samuel Mehr______.
A.conducted more than one research
B.interviewed many American adults
C.taught two groups of 4-yetr-olds music and arts
D.offered children a fast way to be admitted to the best schools
【小題4】The artical may be taken from a report about _____.

What's going to happen in the future? Will robots take over our planet? Will computers become smarter than us? Not likely. But here are some things that scientists say are most likely to happen 10 to 30 years later from now, according to the BBC.
1.Digital money
We used to pay with cash for everything we bought. Now when we swipe(刷) our bus pass or use a credit card to shop online, money is spent without us even seeing it. In fact, we are already using one type of digital money.
You have to admit that using a card is much easier than searching your pockets for change. It is also safer than carrying a lot of cash.
When ATM cards were first introduced, they were not accepted everywhere. But now it's hard to live without them. People in Sweden completely stopped using cash last year, according to the Associated Press, and the US might be next.
2.Bionic(能力超人的)eye
It's no longer something only in a sci­fi movie. People who are blind may have a chance to get their sight back—by wearing bionic eyes.
A blind eye can no longer sense light, but a bionic eye can use a camera to “see” the environment and send data directly to the brain.
Although the bionic eye that's out now only allows patients to see lights and unclear shapes, a high­resolution(高清晰度的) version could be just a few years away.
3.Self­driving cars
Everything is going automatic these days—washing machines, ticket selling machines and even cars. Unlike a human driver, a self­driving car won't get distracted by a phone call, the radio or something outside the window. Sensors and cameras on the car would allow it to stick strictly to the rules of the road and keep a safe distance from other cars. This would greatly reduce the number of road accidents. You could even take a nap while the car drives itself.
Many vehicle companies are now planning self­driving cars. “By 2040, driverless vehicles will be widely accepted and possibly be the dominant vehicles on the road,” said Jeffrey Miller, professor at the University of Alaska Anchorage, US, in Wired magazine.
【小題1】The underlined word “distracted” in the article is closest in meaning to “________”.

A.directedB.discouraged
C.attackedD.disturbed
【小題2】Jeffrey Miller's attitude towards self­driving cars is ________.
A.optimisticB.pessimistic
C.doubtfulD.cautious
【小題3】Which section is the article most likely to be found in the newspaper?
A.Learning KitB.Campus Trends
C.EntertainmentD.Technology

Can people change their skin color without suffering like pop king Michael Jackson? Perhaps yes. Scientists have found the gene that determines skin color.
The gene comes in two versions, one of which is found in 99 percent of Europeans. The other is found in 93 to 100 percent of Africans, researchers at Pennsylvania State University report in the latest issue of Science.
Scientists have changed the color of a dark-striped zebra-fish(斑馬魚) to uniform gold by inserting a version of the pigment (色素) gene into a young fish. As with humans, zebra-fish skin color is determined by pigment cells, which contain melanin (黑色素). The number, size and darkness of melanin per pigment cell determine skin color.
It appears that, like the golden zebra-fish, light-skinned Europeans also have a mutation (變異) in the gene for melanin production. This results in less pigmented skin.
However, Keith Cheng, leader of the research team, points out that the mutation is different in human and zebra-fish genes.
Humans acquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays of the sun (太陽光紫外線), which can cause skin cancer.
But when modern humans leave Africa to live in northern latitudes, they need more sunlight on their skin to produce vitamin D. So the related gene changes, according to Cheng.
Asians have the same version of the gene as Africans, so they probably acquired their light skin through the action of some other gene that affects skin color, said Cheng.
The new discovery could lead to medical treatments for skin cancer. It also could lead to research into ways to change skin color without damaging it like chemical treatment did on Michael Jackson.
【小題1】The passage mainly tells us that ________.

A.people can not change their skin color without any pain
B.the new discovery could lead to research into ways to change skin color safely
C.pop king Michael Jackson often changed his skin color as he liked
D.scientists have found out that people’s skin color is determined by the gene
【小題2】It can be inferred from the passage that _____________.
A.nowadays people who want to change their skin color have to suffer a lot from the damage caused by the chemical treatment
B.Europeans and Africans have the same gene
C.the new discovery could help to find medical treatments for skin cancer
D.there are two kinds of genes
【小題3】Scientists have done an experiment on a dark-striped zebra-fish in order to _____________.
A.find the different genes of humans’
B.prove the humans’ skin color is determined by the pigment gene
C.find out the reason why the Africans’ skin color is dark
D.find out the ways of changing people’s skin color
【小題4】 The reason why Europeans are light-skinned is probably that _____________.
A.they are born light-skinned people
B.light-skinned Europeans have mutation in the gene for melanin production
C.they have fewer activities outside
D.they pay much attention to protecting their skin
【小題5】The writer’s attitude towards the discovery is ______________.
A.neutral B.negative C.positive D.unconcerned

People in several American states may be surprised to see cars on city streets without a driver. Experimental driverless vehicles now are legal in Florida, Nevada and California. They are pointing the way to a future that is not far down the road. The high-tech company Google has a number of self-driving cars, which had covered 480,000 kilometers by August. Volvo is among the companies doing road tests and says it plans to sell driverless cars by 2020.
In September, California Governor Jerry Brown signed an act to allow autonomous vehicles on the roads of his state. " Today we're looking at science fiction becoming tomorrow's reality-the driverless car. " The technology for these cars includes cameras, radar and motion sensors. The systems have been improved through competitions sponsored by the U. S. government agency DARPA. Engineer Richard Mason of the Rand Corporation helped design driverless vehicles for DARPA challenge races.
Cars have become much more fuel-efficient, and new electronic features are' making Hondas safer, said Angie Nucci of Honda America. " A camera on the passenger-side mirror actually engaged on your guiding screen so you can safely change lanes. " Other safety features include warning systems on the front and the sides of the cars. These systems help drivers , but don't replace them. Curator Leslie Kendall of the Petersen Automotive Museum said autonomous cars will make the high ways safer.
"By taking out drivers, you also remove most risks of an accident," Kendall said. He said consumers, however, may be unwilling to lose control. "It may take them time to come to realize that the technology is indeed reliable, but it will have to prove itself first. "
Mason said the technology already works and the biggest challenge now is getting down the cost for driverless vehicles from hundreds of thousands of dollars to something more affordable. He said this will happen as the technology is improved.
【小題1】What can we learn from Paragraph l?
A. Driverless vehicles are now legal in the whole USA.
B. Volvo will be the first to sell driverless cars.
C. Driverless cars are pointing us' a faraway future.
D. Google's self-driving cars have covered a long distance.
【小題2】We learn that Governor of California Jerry Brown_________.

A.helped design self-driving cars.

A smart phone (智能手機) is a mobile phone built on a mobile operating system, with more advanced computing abilities than a common phone. The first smart phones enabled the users to send and receive emails. Later models added the function of portable media players, pocket video cameras, and GPS navigation (導航) units to form one multi-use device. Many modern smart phones also include touchscreens and web browsers (瀏覽器) that display web pages.
A recent report says we spend an average of two hours and 40 minutes each day looking at a smart phone. That doesn’t mean making calls, but playing phone games and browsing the Web.
Nowadays we always find people checking emails in a restaurant, taking a picture of the food when it arrives, or checking a message during a conversation instead of traditional communication. It’s no secret that our lives are being affected by our smart phones obsession.
However, this phenomenon has never been presented so vividly as in the short YouTube film I Forgot My Phone. Despite only being online for a few days, it's already been viewed more than 10.5 million times. Whether it will be screened in the cinema remains to be seen.
Ironically, YouTube’s data show that the site gets a billion views per day from mobile devices, so a lot of those people watched it on their phones.
The short film, written by and starring actress Charlene Deguzman, shows groups of people in various social situations, the majority of whom are absorbed in their phones instead of the world around them. To a certain extent, we all do it.
【小題1】People prefer a smart phone to a common one, because the latter only can help us ______.

A.check emails B.send messages C.find the destination D.watch a video

The United States is not part of the Kyoto Protocol.But since 2005 more than 1,000 mayors across the country have agreed to sign their own version of the protocol.
It is called the United States Conference of Mayors' Climate Protection Agreement.Local leaders have agreed to follow the suggestions of the Kyoto Protocol in their communities.They have also agreed to urge state and federal governments to follow these suggestions.One goal is to reduce air pollution to the 1990 levels by 2012.
A “green” city might work on several kinds of environmental goals and programs.These include air quality,reducing electricity use, green building, public health, the reuse of materials, water quality and clean transportation.
The Natural Resources Defense Council works to protect the environment through action, law and science.One of its online projects is called Smarter Cities, which lists some cities that have made important environmental steps.
Washington,D.C.is also a leading city for green roofs,with over 92,000 square meters of green rooftops.The city also launched a program called “Skip the Bag,Save the River.”Stores charge people a five­cent  tax for using plastic or paper shopping bags instead of reusable bags.Money from the tax will be used to clean up a local river.
New York City is using water as a renewable energy source.For several years, the city has experimented with water in the East River to create energy.Officials operating the program recently asked for permission to put into place 30 river turbine devices.
The people of Portland, Oregon are among the top recyclers in the nation.People living there recycle over half of the waste they throw out.The city has also worked to provide green transportation by providing safe bike paths and free parking spaces where electric cars can get recharged.
In Oakland, California, you can ride on one of several public hydrogen­powered(氫氣作燃料的) buses.These buses release zero pollution into the air.However,they cost about five times more than common buses.

Play allows children to use their creativity while developing their imagination and physical, cognitive (認知的), and emotional strength. Play is important to healthy brain development. Play allows children to create and explore a world they can master, conquering their fears while practicing adult roles. Undirected play allows children to learn how to work in groups, to share, to negotiate, and to resolve conflicts.
Ideally, much of play involves adults, but when play is controlled by adults, children acquiesce (順從) to adult rules and concerns and lose some of the benefits play offers them, particularly in developing creativity, leadership, and group skills. In contrast to passive entertainment, play builds active, healthy bodies. In fact, it has been suggested that encouraging unstructured play may be an exceptional way to increase physical activity levels in children, which is one important strategy in the resolution of the obesity problem.
Children’s development is critically influenced by appropriate, affective relationships with loving and consistent caregivers as they relate to children through play. When parents observe their children in play or join with them in child-driven play, they are given a unique opportunity to see the world from their children’s vantage point as the child navigates a world perfectly created just to fit his or her needs. The interactions that occur through play tell children that parents are fully paying attention to them and help to build enduring relationships. Parents who have the opportunity to look at their children’s world learn to communicate more effectively with their children and are given another setting to offer guidance. Less verbal children may be able to express their views, giving their parents an opportunity to gain a fuller understanding of their perspective. Quite simply, play offers parents a wonderful opportunity to engage fully with their children.
Play is essential to the academic environment. It ensures that the school setting attends to the social and emotional development of children as well as their cognitive development. It has been shown to help children adjust to the school setting and even to strengthen children’s learning willingness. Social-emotional learning is best integrated (融合) with academic learning; it is concerning if some of the forces that enhance children’s ability to learn are improved at the expense of others. Play and unscheduled time that allow for peer interactions are important components of social-emotional learning.
【小題1】Compared with undirected play, play which is controlled by adults ________.

A.doesn’t benefit the children at all 
B.doesn’t help develop leadership and group skills  
C.makes children become more active  
D.helps increase physical activity levels 
【小題2】The third paragraph mainly tells us that ________.
A.play offers parents a good chance to establish good relationships with children 
B.children’s development is greatly influenced by relationships with parents 
C.play helps children better express their views 
D.play offers parents a unique opportunity to see the world from a different perspective 
【小題3】From the last paragraph, we know that ________.
A.play can’t help children become adapted to the school setting 
B.play makes social-emotional learning and academic learning separated 
C.play is beneficial to social-emotional learning as well as academic learning 
D.it is necessary to strengthen children’s academic development at the expense of others 
【小題4】Which of the following statements is NOT true?
A.Undirected play can help children develop team spirit. 
B.Play can improve children’s willingness to learn. 
C.Play helps adults gain a better understanding of the children’s thoughts. 
D.Adults shouldn’t be involved in children’s play.
