    You don't need to get in a time-traveling machine to see how technology will reshape our lives, such as the way we shop．Several new technologies that are to change your buying habits already exist．Let's see what's in store for your future shopping．
    Try it on, virtually （虚拟的）．Want to shop online for a new pair of eyeglasses? You don't need to guess which pair looks best on you. Go and see the eBay Fashion iPhone app to try a pair of eyewear you're checking out on a picture of your face．But what if you want to buy something bigger? Thanks to Microsoft Kinect's motion tracking camera, you can cover clothes on your screen body．You can even choose the background of your virtual fitting room to enrich your shopping experience．
    Get a perfect, custom fit．Everyone's body is shaped differently．To get a perfect fit, you sometimes have to get your clothes changed．But by using 3D scanning technology, all the clothes you buy will fit your body perfectly．Some companies scan your body using High-tech to get the most accurate measurements, so they can make special clothes just for you．
    High-tech shopping carts and checkout counters．High-tech shopping carts could, in time, be a common sight in malls and supermarkets．Microsoft Kinect-enabled carts are currently under test．The cart can follow you along the aisles （通道）, controlled merely by your movement and your voice．In China, a supermarket chain introduced tablet-equipped carts that guide shoppers around the stores' aisles．
    In the United States, several supermarkets use a device called Scan It that gives buyers the freedom to scan purchases on their own while they shop．While it's great not having to line up at a checkout counter, we wouldn't mind it if the store used Toshiba's new Object Recognition Scanner．The machine identifies a product as soon as it's placed in front of a camera just by its shape and color, even if it has no bar code．

    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. “
    小题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
    小题2:The underlined phrase “fussed over” in the third paragraph probably means______.
    A．paid attention toB．related toC．put pressure onD．counted on
    小题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
    小题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

    As they migrate (迁移), butterflies and moths choose the winds they want to fly with, and they change their body positions if they start floating in the wrong direction. This new finding suggests that insects may employ some of the same methods that birds use for traveling long distances. Scientists have long thought that insects were simply at the mercy of the wind.
    Fascinating as their skills of flight are, migrating behavior has been difficult to study in   insects because many long distant trips happen thousands of feet above ground. Only recently have scientists developed technologies that can detect (测出) such little creatures at such great heights.
    To their surprise, though, the insects weren’t passive travelers on the winds. In autumn, for example, most light winds blew from the east, but the insects somehow sought out ones that carried them south and they positioned themselves to navigate directly to their wintering homes.
    Even in the spring, when most winds flowed northward, the insects didn’t always go with the flow. If breezes weren’t blowing in the exact direction they wanted to go, the insects changed their body positions to compensate (补偿). Many migrating birds do the same thing.
    The study also found, butterflies and moths actively flew within the air streams that pushed them along. By adding flight speeds to wind speeds, the scientists calculated that butterflies and moths can travel as fast as 100 kilometers an hour. The findings may have real-world applications. With climate warming, migrating insects are growing in number. Knowing how and when these pests move could help when farmers decide when to spray their crops.
    小题1:What’s the main idea of the text?  
    A．Insects migrate with the seasons．
    B．Wind helps insects greatly in migrating．
    C．Windsurfing insects have real direction．
    D．Scientists have trouble in observing insects．
    小题2:Scientists originally thought that ________．
    A．insects always waited for their favorable winds
    B．insects chose the winds they wanted to ride
    C．insects were just blown about by the wind
    D．insects positioned themselves in the winds
    小题3:It is not easy to study the migrating behavior of the insects because ________．         
    A．the little creatures can fly very fast
    B．they have no regular migrating courses
    C．the wind’s direction is hard to foresee
    D．their flight is long and high above ground
    小题4:We can learn from the text that _________．          
    A．insects fly in the way birds do
    B．insects travel more easily in autumn
    C．insects never position themselves when flying low
    D．insects rest a lot when the wind pushes them along
    小题5:According to the passage, the findings can__________．             
    A．increase insects in numberB．instruct farmers when to spray
    C．prevent climate warmingD．help protect insects

    Animals are considered to be endangered if the species is close to extinction throughout all or most of its environment. Animals become endangered for a variety of reasons.
    Some animals become endangered when their habitats contain resources for humans. For example, commercial forest cutting in the Amazon Rainforest has seriously reduced the population of many animal species and lead to the extinction of other groups. Land itself is an important resource to humans since it provides us with living space, and when people replace animal habitats with human habitats, it can lead to larger loss of natural species.
    Commercial and industrial operations may reduce land or water for animals and pollute their environment. Due to water pollution, the baiji, a fresh water dolphin native to China, was declared extinct, meaning it’s unlikely the population can recover. Even noise pollution from human activities can lead to the disorder of animal behavior.
    Another cause that makes animals become endangered is over-fishing or over-hunting. Over-hunting whales led to near extinction of many species of whales.
    The introduction of a non-native species to a habitat may make animals become endangered. The native species may not defend against a new one, and the effects can be dangerous. In Australia, the introduction of the common house cat led to the extinction of the red-fronted parakeet and has seriously damaged the populations of several small animals.
    Introduced species can also bring new diseases with them. As a result, animals become endangered. Native animals may not have the power to fight against non-native diseases, and population levels can suffer. Another cause of disease is human-introduced chemicals. The use of DDT is believed to be one of the leading causes in driving the California Condor to near extinction.
    When animals become endangered, the entire food chain can be affected. For example, in 2008 disease seriously harmed the honeybee, which is largely responsible for pollinating(授花粉)  plants, including many fruits and vegetables. Without their pollination, a very large part of the human diet could be reduced. In fact, if the honeybee should become extinct, our life would be affected and billions of dollars would be lost. Therefore, many people argue that when animals become endangered it is in man’s own self-interest to protect them.
    小题1:The passage is mainly about ______.
    A．ways of protecting animals’ habitats
    B．effects caused by species endangerment
    C．dangers of bringing in non-native species
    D．reasons why animals become endangered
    小题2:Which of the following examples shows that environmental pollution may cause species endangerment?
    A．The extinction of the whales.
    B．The extinction of the red-fronted parakeet.
    C．The decreasing population of the dolphin.
    D．The effect of the honeybee on the human diet.
    小题3:Why is it dangerous to introduce a non-native species to a habitat?
    A．Native species are likely to die from the new diseases.
    B．It’s hard for non-native species to survive.
    C．Non-native species will take up more space.
    D．Native species are so powerful for non-native species.
    小题4:The California Condor is in danger of dying out because of ______.
    A．loss of habitatB．harmful chemicals
    C．forest cuttingD．unfamiliar diseases
    小题5:We can infer from the last paragraph that ______.
    A．humans are to blame for species extinction
    B．small animals mean little to the whole food chain
    C．protection of the honeybee has cost billions of dollars
    D．humans protect animals for the benefit of themselves

    Play allows children to use their creativity while developing their imagination and physical, cognitive (认知的), 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 (顺从) 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.
    小题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
    小题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
    小题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
    小题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.

    We are always told that TV is not good for us. If it is true, how come the TV-addicted kids of our young generation nowadays are much smarter than we are? In my family, the only persons who can work the TV remote control well are the children.
    Probably TV really educates us. For example, we can learn a very useful medical fact: A man that has been shot always has time to speak a broken sentence when he is dying. “The killer was…” (dies)
    But I suppose the biggest things that we learn from TV can be regarded as “Life Skills”. Bad things simply happen on either stormy or dark nights. Emotional breakdowns make people wander in the heavy rain without raincoats or umbrellas. And contrary to the scientists, the crack of lightning and the accompanying flash come on at exactly the same time, wherever the scenes are.
    I’ve even got to know useful geographical facts from science-fiction shows: Aliens only speak the language of English no matter which planet they come from.
    To make good use of something that we learn from TV can make our security better. Consider these truths. When you are really attacked by 20 bad guys, you needn’t worry about your being outnumbered. The criminals will hang back and take turns to approach you in ones and twos just so you can conveniently defeat them all. Bad guys who are completely covered in black clothes always remove their black masks to reveal that they are in fact, aha, women.
    TV often teaches us a lot of important information as well about escaping from danger. Watch and learn. (1) If anyone is running after you down a passage, you will find that boxes have been conveniently placed near all the walls you need to jump over. (2) If you are tall and handsome, you can run from any number of armed criminals, and every shot will miss you.
    Be warned, however, if your name card says “henchman” (帮凶) and you are part of a group of plain-looking people trying to catch a handsome individual, a single shot will kill you. But don’t be anxious: TV also delivers useful information for bad guys. All cars are inflammable (易燃的) and have amazing shock absorbers that enable them to fly into the air and land without damage — except police cars.
    TV even teaches us about TV. Whenever anyone turns on a TV, it shows a news flash about someone they know. They then turn the box off immediately after that news item.
    小题1: When the writer says “A man that has been shot always has time to speak a broken sentence when he is dying” (Paragraph 2), he shows his________.
    A．humorB．sympathyC．deep concernD．medical knowledge
    小题2: We can learn from Paragraph 3 that in the real world________.
    A．bad things cause people to break down in the rain
    B．bad things never happen on dark and stormy nights
    C．people with emotional problems like to walk in the rain without umbrellas
    D．you can’t hear the crack of lightning and see the accompanying flash exactly at the same time
    小题3: On TV what usually happens when a person turns it on?
    A．The program shown is always about the importance of TV.
    B．The person always turns off the TV when it’s time for news.
    C．The news shown is always about someone the person knows.
    D．TV always shows news about famous people.
    小题4: What’s the main idea of this passage?
    A．Life skills can be learned from TV.
    B．What happens in TV is quite different from reality.
    C．Watching TV makes people more creative.
    D．TV plays an important role in society.
    小题5: The writer of this passage takes a(n) ________ attitude towards TV plays.
    A．positiveB．casualC．negativeD．indifferent

    Some students get so nervous before a test; they do poorly even if they know the material. Sian Beilock has studied these highly anxious test-takers.
    Sian Beilock: “They start worrying about the consequences. They might even start worrying about whether this exam is going to prevent them from getting into the college they want. And when we worry，it actually uses up attention and memory resources. I talk about it as your cognitive horsepower that you could otherwise be using to focus on the exam.”
    Professor Beilock and another researcher，Gerardo Ramirez，have developed a possible solution. Just before an exam，highly anxious test-takers spend ten minutes writing about their worries about the test.
    Sian Beilock: “What we think happens is when students put it down on paper，they think about the worst that could happen and they reappraise the situation. They might realize it’s not as bad as they might think it was before and，in essence(本质上)，it prevents these thoughts from popping up when they’re actually taking a test.”
    The researchers tested the idea on a group of twenty anxious college students. They gave them two short math tests. After the first one, they asked the students to either sit quietly or write about their feelings about the upcoming second test.
    The researchers added to the pressure. They told the students that those who did well on the second test would get money. They also told them that their performance would affect other students as part of a team effort.
    Professor Beilock says those who sat quietly scored an average of twelve percent worse on the second test. But the students who had written about their fears improved their performance by an average of five percent.
    Next, the researchers used younger students in a biology class. They told them before final exams either to write about their feelings or to think about things unrelated to the test.
    Prefessor Beilock says highly anxious students who did the writing got an average grade of  B+，compared to a B－ for those who did not.
    Sian Beilock: “What we showed is that for students who are highly test-anxious，who’d done our writing intervention(排解)，all of a sudden there was no relationship between test anxiety and performance. Those students most likely to worry were performing just as well as their classmates who don’t normally get nervous in these testing situations.”
    But what if students do not have a chance to write about their fears immediately before an exam or presentation? Professor Beilock says students can try it themselves at home or in the library and still improve their performance.
    小题1:Which of the following is TRUE?
    A．The result in the math test agrees with that in the biology test.
    B．In the first math test, students who sat quietly performed better.
    C．In the second math test, students who wrote about their feelings did worse.
    D．Some college students are highly anxious test-takers while others are not in the tests.
    小题2:What may happen if students have the problem of test anxiety?
    A．Test anxiety is sure to cause students to fail the test.
    B．Test anxiety can improve students’ performance to some degree.
    C．Students’ attention and memory resources run out when worried.
    D．Students may not be admitted into their favorite college if worried
    小题3:The result of the research suggests that ________．
    A．proper amount of burden may turn out to be a good thing
    B．facing the fears bravely may help one to achieve more
    C．avoiding facing the problem may contribute to relaxation
    D．taking no action before difficulty may result in success
    小题4:What is the main idea of the passage?
    A．It is important for students to overcome test anxiety.
    B．Anxious students overcome test anxiety by writing down fears.
    C．It is a common practice for students being worried before a test.
    D．Being worried before tests does harm to students’ performance.

    Astronomers have captured(捕获) the first direct image of a planet being born.
    Adam Kraus, of the University of Hawaii’s Institute for Astronomy, said the planet is being formed out of dust and gas circling a 2-million-yea-old star about 450 light years from Earth.
    The planet itself, based on scientific models of how planets form, is believed to have started taking shape about 50,000 to 100,000 years ago.
    Called LkCa 15b, it’s the youngest planet ever observed. The previous record holder was about five times older.
    Kraus and his colleague, Michael Ireland from Macquarie University and the Australian Astronomical Observatory, used Keck telescopes on Mauna Kea(a volcano on the island of Hawaii, US) to find the planet. Kraus presented the discovery Wednesday at NASA’s Goddard Space Flight Center in Maryland.
    Observing planets while they’re forming can help scientists answer questions like weather planets form early in the life of a star or later, and whether they form relatively close to stars or father away.
    Planets can change orbits(轨道) after forming, so it’s difficult to answer such questions by studying older planets.
    “These very basic questions of when and where are best answered when you can actually see the planet forming, as the process is happening right now,” Kraus said.
    Scientists hadn’t been able to see such young planets before because the stars they’re circling around outshine(光亮强过) them. Kraus and Ireland used two techniques to overcome this problem.
    One method, which is also used by other astronomers, was to change the shape of the telescope mirrors to remove light distortion(扭曲) created by the Earth’s atmosphere. The other method they used, which was unique, was to put masks with several holes over most of the telescope mirrors. The combination of these techniques allowed the astronomers to obtain high-quality images that let them see the planet next to the bright star.
    The star LkCa 15—the planet is named after its star—was the team’s second target. They immediately knew they were seeing something new, so they plan to gather more data on the star.
    小题1:The research on younger planets helps scientists _____________.
    A．study why planets change orbits after forming
    B．understand how planets move around their stars
    C．answer questions about the age of stars and planets
    D．know the relationship between planets and their stars
    小题2:Why are young planets like LkCa 15b hard to discover?
    A．Their stars are brighter than them..B．They are very far from the earth.
    C．They are generally too small.D．They rarely form.
    小题3:According to the text, Kraus and Ireland _____________.
    A．have been working in the same university
    B．observed the planet on a volcano in Hawaii
    C．used two new methods in the observation
    D．cut holes in the mirrors when observing
    小题4:Which of the following would be the best title for the text?
    A．Youngest planet seen as it’s forming.
