    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

    1. 1.

      The purpose of the experiment is ______

      1. A.
        to find the frequency of people’s yawning
      2. B.
        to indicate brain can regulate temperature naturally
      3. C.
        to prove people yawn in winter and in summer equally
      4. D.
        to show the real reason why people yawn
    2. 2.

      The information we get from Paragraphs 5 and 6 is that ______

      1. A.
        longer outdoor summertime results in more yawns
      2. B.
        yawning frequency increases with outdoor time
      3. C.
        yawning frequency changes with outdoor time
      4. D.
        longer outdoor wintertime leads to fewer yawns
    3. 3.

    Sparrow is a fast-food chain with 200 restaurants. Some years ago, the group to which Sparrow belonged was taken over by another company. Although Sparrow showed no sign of declining, the chain was generally in an unhealthy state. With more and more fast-food concepts reaching the market, the Sparrow menu had to struggle for attention. And to make matters worse, its new owner had no plans to give it the funds it required.
    Sparrow failed to grow for another two years. Until a new CEO, Carl Pearson, decided to build up its market share. He did a survey, which showed that consumers who already used Sparrow restaurants were extremely positive about the chain, while customers of other fast-food chains were unwilling to turn away from them. Sparrow had to develop a new promotional campaign.
    Pearson faced a battle over the future of the Sparrow brand. The chain’s owner now favored rebranding Sparrow as Marcy’s restaurants. Pearson resisted, arguing for an advertising campaign designed to convince customers that visits to Sparrow restaurants were fun. Such an attempt to establish a positive relationship between a company and the general public was unusual for that time. Pearson strongly believed that numbers were the key to success, rather than customers’ speeding power. Finally, the owner accepted his idea.
    The campaign itself changed the traditional advertising style of the fast-food industry. The TV ads of Sparrow focused on entertainment and featured original sons performed by a variety of stars. Instead of showing the superiority of a specific product, the intension was to put Sparrow in the hearts of potential customers.
    Pearson also made other decisions which he believed would contribute to the new Sparrow image. For example, he offered to lower the rent of any restaurants which achieved a certain increase in their turnover. (营业额)
    These efforts paid off, and Sparrow soon became one of the most successful fast-food chains in the regions where it operated

    1. 1.

      Which was one of the problems Sparrow faced before Pearson became CEO?

      1. A.
        The number of its customers was declining

        It was in need of financial support
      3. C.
        Its customers found the food unhealthy
      4. D.
        Most of its restaurants were closed

        Sparrow restaurants
      3. C.
        other fast-food chains
      4. D.
        Customers of other fast-food chains
    3. 3.

      For what purpose did Pearson start the advertising campaign?

      1. A.
        To stress the unusual tradition of Sparrow
      2. B.
        To lean about customers; spending power
      3. C.
        To meet the challenge from Marcy’s restaurants
      4. D.
        To build a good relationship with the public

    Pop music is the name for different forms of popular, commercial(商业) music. It had its beginning in the USA and spread throughout the whole world during the 1950s and 1960s. It is widely liked by the young people. The best known early form of pop music was “rock’ n’ roll”; another was “blues”. A more recent development is “folk-rock”. Pop music has taken the place of native music in many parts of the world; it has caused the number of people for jazz to become much smaller than it was in the 1950s and earlier, and it has now begun to rule musical stage productions. It’s a big industry. Much pop music is without artistic value, but the work of some pop singers, e.g. the Beatles, Bob Dylan, the groups like Floyd and Crosby, Stills and Nash, is on a higher musical level.

    In Wiltshire, England, volunteers are being sought to visit a nature protection area to count the butterflies living there and on surrounding fields. The project is promoted by all environmental protection organization, which has contributed to improving the living environment for wild animals. Recently, the organization has issued an appeal to help it observe environmental changes based on the record of butterflies and protect the environment.
    In the area, the local people have planted many special flowers with the help of the organization, aiming to see whether these flowers will interest the rare and beautiful butterflies. The project officer Sarah Marshall says,“It will be a suitable habitat (栖息地) for butterflies. They are great‘indicator species’ as they are easily affected by climate changes so they make a brilliant early-warning system for the environment.” She also points out that volunteers are needed to record the number or species of butterflies, and based on the change happening to the butterflies, the hidden environmental problems in the area can be found out in time.
    The organization is seeking volunteers to help monitor butterflies from April through to September. They will walk a fixed route and record the different butterflies they encounter along the way. Each visit should take no more than two hours, and each volunteer is expected to visit once a month to count the wildlife. “Staff will provide back up, so if the weather is poor on the day you are to visit (butterflies don’t like to fly in the rain, wind or if it’s too cloudy) we can have someone else do your job,” Sarah points out.
    No previous experience is necessary as training and support will be provided, but a keen interest is essential. If you are interested please contact Sarah on (01380) 725670, ext 278, email—sarahm @ wiltshirewildlife. org

    Removing the sleeve(封套), you will find a book that is entirely white, except for the names of its author and subject in elegant black type on the cover. It is the perfect design for the biography of a man who insisted that even the insides of his products be perfectly constructed, and that his factory wails flash in the whitest white.
    The cover was the only part of the book Steve Jobs wanted to control, writes Isaacson in his introduction. Though Mr. Jobs pushed the biographer of Albert Einstein and Benjamin Franklin to write in his own way, generously allowing the writer more than 40 interviews, this book offers quite a different view of Mr. Jobs, who won much praise from his fans after his death on October 5th at the age of 56.
    As a biographer of Albert Einstein and Benjamin Franklin, Mr. Isaacson knows how to celebrate long-dead genius, but he claimed that "Steve Jobs" would not be entirely praiseful words. The picture he paints, particularly in the first half of this book, is not nice. Mr. Jobs emerges as a controlling and often cold-blooded character. A child of the 1960s counter-culture (反主流文化), he hated, materialism and lived in simply furnished houses ( in part because he was too particular about furniture). But when Apple went public in 1980, he refused to give any share to Daniel Kottke, a Iongtime supporter and soul mate from college. "He has to abandon the people he is close to," observes Andy Hertzfeld, an early Apple engineer.
    Mr. Jobs was undoubtedly possessing an extraordinary ability to attract others and inspire a kind of faith that could not be questioned. But also he could be cold and cruel. If he disapproved of an employee's work, he often shamed him. "This is who I am," he once said after being challenged,"and you can't expect me to be someone I'm not. " This disgusting personality wasn't always helpful,but it served a purpose, writes Mr. Isaacson, many would "end their chain of horror stories by saying that he got them to do things they never dreamed possible. "
    Mr. Isaacson treats "Steve Jobs" as the biography of record, which means that it is a strange book to read so soon after its subject's death

    1. 1.

      The biography for Jobs is believed to have the perfect design because __

      1. A.
        it follows Jobs' style
      2. B.
        its cover is entirely white
      3. C.
        black and white are his favorite
      4. D.
        it is designed by a famous biographer
    2. 2.

      The picture of Jobs that Isaacson paints in his book is _________

      ①cruel    ②humorous   ③particular  ④generous

      1. A.
        ①③
      2. B.
        ②③
      3. C.
        ①④
      4. D.
        ③④
    3. 3.

      It can be safely concluded that        

      1. A.
        Jobs is highly spoken of in the book
      2. B.
        Isaacson doesn't think Jobs a good man
      3. C.
        Jobs didn't care about the design of the book
      4. D.
        all descriptions of Jobs are not nice in the book
    4. 4.

      This passage can be classified as          

      1. A.
        a personal diary
      2. B.
        a book review
      3. C.

    Despite the fact that it has never been seen almost everyone is familiar with the legendary unicorn(独角兽). Descriptions of unicorns have been found dating from ancient times. The great philosopher Aristotle theorized that there were two types of unicorn--- the so-called Indian Ass and the Oryx, a kind of antelope. Unicorns are often used in the logo of a noble family, town council or university as their special sign. Even Scotland is represented by a unicorn.
    According to the legend, anyone attempting to catch a unicorn had to be extremely careful as it was very fierce and dangerous. A clever trick suggested by unicorn-trappers, in order to catch this amazing animal without being hurt by its horn, was for the hunter to stand in front of a tree and then to move quickly behind it as the unicorn dashed angrily. Hopefully, the creature could then be caught when its horn was stuck in the tree.
    When hollowed out and used as a drinking-cup, the unicorn’s horn was said to have the power to offer protection against person. It was believed that nobody could be harmed-by drinking the contents of a unicorn’s horn. Right up until the French Revolution in 1789, the French court was said to have used cups made of “unicorn” horn in order to protect the king. In addition, the horn was said to have medicinal value, so much so that it could be sold for more than ten times the price of the same weight of gold. What, then, was “unicorn” horn? We know at times the rhino(犀牛) was confused with this legendary creature. A drinking-cup supposedly made of “unicorn” horn was discovered to be made of the horn of a rhino

      4. D.
        It could be the symbol of a university
    2. 2.

      To catch a unicorn, the unicorn-trappers had to try all of the following EXCEPT ____

        attracting the unicorn to attack
      2. B.
        making use of the tree as a defense
      3. C.
        hiding quickly behind the unicorn
      4. D.
        having the unicorn horn stuck in the tree

    The National Dark-Sky Week (NDSW) is a week during which people all over the United States turn off their lights to enjoy the beauty of the night sky without light pollution. This even was started by Jennifer Barlow of Midlothian, Virginia in 2003, and it is becoming more popular each year. It has been supported by the International Dark-Sky Association, the American Astronomical Society, and the Astronomical League.
    This even always occurs in April, during the week of the new moon so that the sky can be as dark as possible for the best viewing conditions.
    “It is my wish that people could see the night sky without other light in the sky as our ancestors (祖先) saw it hundreds of years ago,” explains Barlow.
    Since it only lasts a week and not everyone in the country will take part in it, how will the National Dark-Sky Week reduce light pollution? The main goal of NDSW is to increase awareness (意识) of the harmful effects of light pollution. It is not possible for all of the light pollution in this part of the world to disappear. However, it is possible to make a small difference in the quality of the night sky. Another goal of this even is to promote (促进) the use of better lighting systems that direct light toward the ground instead of up into the sky.
    Jennifer Barlow states, “The night sky is a gift of such beauty that it should not be polluted by wasted light. In this way, our children will not lose touch with the wonder of our universe.”

    1. 1.

      This passage is mainly about______.

      1. A.

      3. C.
        the harm of light pollution
      4. D.
        the beauty of the night sky

    Dear Michelle,
    My Dad hates my Mom. He tells me that she is a liar and that I should not trust her. Of course, they are divorced but they have “joint custody” (共同监护). What a joke! I am 15, my brother is nine, and we have a life of hell, frankly.
    We live one week on and one week off. This was the brilliant idea of both of my parents, which was fair to them but ruining my life. I cannot get away from his voice and his putting my mom down. Sometimes I think about running away.
    A Hopeless Ant
    Dear Hopeless Ant,
    First, thank you for trusting me with your problem. If all you said is correct, then there are several things that you can and should do to help yourself, your brother, and oddly enough, your parents.
    You need a family counselor. Such a person could listen to each family member alone and then meet together to talk about the situation.
    If refused, you need to talk to a counselor in your school. You need to be heard, and you need an adult who will listen. A school counselor can organize a meeting with your parents.
    Perhaps you need to write to your mother. Writing things down allows people to go over it more than one time.
    I cannot imagine that she will stand passively by and do nothing at all to help once she reads how you feel. Your father needs a letter as well. He may not realize the destructive effect that it has on his children.
    Lastly, have a plan in mind when all else fails that is not self-destructive. Life passes very quickly, sweetheart, and you will grow up and have your own life.
    Until then, you need to keep yourself safe. Never doubt that it will get better. Write back and let me know how everything is going.
    Michelle

    You can’t always predict a heavy rain or remember your umbrella. But designer Mikhail Belvacv doesn’t think that forgetting to check the weather forecast before heading out should result in you getting wet. That’s why he created lampbrella, a lamp post with its own rain sensing umbrella.
    The designer says he come up with the idea after watching people get wet on streets in Russia. “once, I was driving on a central Saint Petersburg street and saw the street lamps lighting up people trying to hide from the rain. I thought it would be appropriate to have a canopy(伞蓬)built into a street lamp.” he said.
    The lampbrella is a standard-looking street lamp fitted with an umbrella canopy. It has a built-in electric motor which can open or close the umbrella on demand. Sensors(传感器)then ensure that the umbrella offers pedestrians shelter whenever it starts raining.
    In addition to the rain sensor, there’s also a 360°motion sensor on the biberglass street lamp which detects whether anyone’s using the lampbrella. After three minutes of not being used the canopy is closed.
    According to the designer, the lampbrella would move at a relatively low speed, so as not to cause harm to the pedestrians. Besides, it would be grounded to protect from possible lighting strike. Each lampbrella would offer enough shelter for several people. Being installed at 2 meters off the ground, it would only be a danger for the tallest of pedestrians.
    While there are no plans to take lampbrella into production, Belyacv says he recently introduced his creation one Moscow Department, and insists this creation could be installed on many streets where a lot of people walk but there are no canopies to provide shelter
