    Humans might be the most highly-evolved species on the planet, but most animals possess skills we can only dream of having. Imagine how much electricity we could save if we could see in the dark the way cats do. Imagine leaping from tree to tree like a monkey. Giraffes, which are otherwise calm and good-natured, sleep only 4.6 hours a day.
    We realized a long, long time ago that nature provides the best blueprint for invention. We’ve borrowed canals from beavers and reflectors from cat’s eyes. Although the words “bionics”(仿生学) became popular only after the 1960s, history shows that nature has always provided ideas on solving everyday problems. Our archives(档案) don’t go back to the time of Leonardo da Vinci and his bird-like flying machines, but we can take you to the late 19th century, where we applied those same principles for building our first practical airplanes.
    To prepare for their flight at Kitty Hawk, the Wright brothers studied the movements of pigeons to figure out how they stayed high up when they were heavier than air. Their success inspired scores of successors to improve on the airplane by studying various aspects of nature. One of Orville Wright’s pupils caught and stuffed seagulls to examine their wingspan. Meanwhile, two French inventors examined spinning sycamore(梧桐) seeds in an effort to apply those same motions, reversed, to a helicopter .
    Some examples are more obvious than others. The outside of the airplane designed by the Wright brothers looks like a minimalistic(简单抽象艺术) structure. On the other hand, Barney Connett’s fish submarine actually looks like a fish.
    Some bio-inspired concepts have yet to be invented. In the 1960s, the US Army commissioned several university professors to conduct research on the motor skills animals in hope of applying those same abilities to tanks. Tanks that run like horses or jump like grasshoppers(蚂蚱)-sounds shocking, doesn’t it? But imagine how life would change if we could achieve that.
    小题1:“Cats”, “monkeys” and “giraffes” mentioned in paragraph 1 are examples to show______.
    A．they are highly-evolved species as humans
    B．animals have skills that humans do not possess
    C．humans can learn animals’ skills
    D．they are skillful in different ways
    小题2:What happened after the Wright brothers’ success?
    A．People carried out a systematic study on pigeons.
    B．People studied more animals and plants to develop the airplane.
    C．People could fly their airplane for fun.
    D．People kept their airplane at a French gallery.
    小题3:Which of the following is true about the research carried out by the US Army?
    A．It has cost a large sum of money.
    B．It has changed our life.
    C．It has improved the abilities of tanks
    D．It has not succeeded yet.
    小题4:What does the writer want to tell in the passage?
    A．many inventions get ideas from nature.
    B．Some animals possess unique skills.
    C．People should protect nature.
    D．Bionics is far from perfect

    小题1:B
    小题2:B
    小题3:D
    小题4:A

    试题分析：人类也许是地球上进化最高级的动物，但是，有许多动物都有着人类无法企及的技能。从莱特兄弟制造飞机开始，人类一直都在从大自然中探索发明创造，这些发明创造给人们的生活带来了很大的改变。
    小题1:根据第一段“but most animals possess skills we can only dream of having.”可知，猫的夜视，猴子的跳跃，长颈鹿短的睡眠时间，许多动物有着人类没有的技能，故选B。
    小题2:根据第三段“Their success inspired scores of successors to improve on the airplane by studying various aspects of nature.”可知，在莱特兄弟之后，许多人开始研究动植物来研制飞机，故选B。
    小题3:根据最后一段“Some bio-inspired concepts have yet to be invented. ...sounds shocking, doesn’t it? But imagine how life would change if we could achieve that.”可知，一些仿生概念尚有待发明，如果美国军方的研究成功的话，会给我们的生活带来什么样的变化？由此可见，美国军方的研究还没有成功，故选D。
    小题4:根据“history shows that nature has always provided ideas on solving everyday problems. ...the Wright brothers studied the movements of pigeons ...One of Orville Wright’s pupils caught and stuffed seagulls ...two French inventors examined spinning sycamore(梧桐) seeds”可知，文章讲的是，人类不断从大自然中获得启发，进而发明出许多解决日常问题的事物，故选A。

    DAVID Beckham. Cristiano  Ronaldo and Rnfacl Nadal while you watch sports and admin* the players’ skills, do you ever notice how handsome the players are?
    Yes, sportsmen tend to be handsome. And they haven’t only attracted the interest of the audience even scientists are now studying their good looks.
    In a recent study, Erik Postma, a biologist at the University of Zurich in Switzerland, collected the headshots（头像）of 80 professional athletes from I hr 2012 Tour He France, a bicycle race held in Franco. The race, which covers 3,200 kilometers in 23 days, is often considered to In* one of the hardest endurance（耐力）events, according to The Telegraph.
    Postma then asked female participants to score the cyclists’ attractiveness.judging them only based on their facial appearances. So, if a participant recognized any of the cyclists, meaning she knew how good he was at the sport, her score wouldn’t count.
    After comparing all the scores with the cyclists’ performances in the 2012 race, Postma was surprised to find that the best riders were rated on average 25 percent more attractive than the worst ones. For example, one of the cyclists, Maxime Monfort , came third in terms of attractiveness and sixth in terms of performance, reported Discovery News.
    But where did women get the ability to single out a good rider by simply looking at his face?
    According lo Postma, evolution (进化) seems to be the answer. In ancient times, women preferred to marry strong men because they would provide good genes for their children. A man with great endurance was also able to cover long distances to hunt for food, which would allow him to better feed the family. “That’s why endurance performance was a key evolutionary factor.” Postma told Discovery News.
    As you can see, it’s not that sportsmen ate more attractive themselves, women were just born to think of them that way.
    Perhaps surprisingly, when Postma did the same test with male participants, he found that men actually had a quite similar view on which riders were handsome. Even
    though most men aren’t aware of it. they inherited (继承) this ability from their ancient past, when it was necessary to “spot potential competitors” , explained Postma.
    小题1:What did Erik Postma ask female participants to do in his study?
    A．To help collect the headshots of professional cyclists from the Tour de France.
    B．To pick out the cyclists whom they are familiar with or appreciate most.
    C．To rate the cyclists’ attractiveness according to facial appearance.
    D．To predict the cyclists ’ performances based on facial appearance.
    小题2:What did Postma discover from his study?
    A．The more attractive a cyclist was, the better he performed in the race.
    B．Generally, a cyclist’s endurance had nothing to do with his attractiveness.
    C．Attractive cyclists proved to have less endurance than those who were less attractive.
    D．Those who performed best in the games were considered more attractive than those who performed worst.
    小题3:What can we conclude from the last three paragraphs?
    A．Women and men hold quite different views on male attractiveness.
    B．Men with good looks tend to lie less popular than men with great endurance.
    C．A man with great endurance appealed to women in ancient times and this remains the same today.
    D．Most men don* t have the same ability as women to single out a good sportsman by simply looking at his face.

    Schooling Matters
    March 25, 2014  Chengdu  Michelle Obama
    You see, the truth is that I grew up like many of you. My mom, my dad, my brother and I, we lived in a tiny apartment in Chicago, which is one of the largest cities in America. My father worked at the local water plant…
    While we certainly weren’t rich, my parents had big dreams for me and my brother. They had only a high school education themselves, but they were determined to send us both to universities.
    So they poured all of their love and all of their hope into us, and they worked hard. They saved every penny. And I know that wasn’t easy for them, especially for my father. You see, my father had serious illness called multiple sclerosis(多发性硬化症). And as he got sicker, it got harder for him to walk, and it took him longer to get dressed in the morning.
    But no matter how tired he felt, no matter how much pain he was in, my father hardly ever missed a day of work, because he was determined to give me and my brother a better life. And every day, like so many of you, I felt the weight of my parents’ sacrifices on my shoulders. Every day, I wanted to make them proud.
    So, while most American kids attend public schools near their homes, when it was time for me to attend high school, I took an exam and got into a special public high school where I could get a better education. But the school was very far from my home, so I had to get up early every morning and ride a bus for an hour, sometimes an hour and a half if the weather was bad. And every afternoon, I’d ride that same bus back home and then immediately start my homework, often studying late into the night – and sometimes I would wake up at 4:30 or 5:00 in the morning to study even more.
    And it wasn’t easy. But whenever I got tired or discouraged, I would just think about how hard my parents were working for me. And I would remember something my mother always told me – she said, “A good education is something that no one can take away from you.”
    小题1:The passage can be sorted as a        ．

    Researchers in the psychology department at the University of California at Los Angeles (UCLA) have discovered a major difference in the way men and women respond to stress. This difference may explain why men are more likely to suffer from stress-related disorders.
    Until now, psychological research has maintained that both men and women have the same "fight-or-flight" reaction to stress. In other words, individuals either react with aggressive behavior, such as verbal or physical conflict ("fight"), or they react by withdrawing from the stressful situation ("flight"). However, the UCLA research team found that men and women have quite different biological and behavioral responses to stress. While men often react to stress in the fight-or-flight response, women often have another kind of reaction which could be called "tend and befriend." That is, they often react to stressful conditions by protecting and nurturing their young ("tend"), and by looking for social contact and support from others - especially other females ('befriend").
    Scientists have long known that in the fight-or- flight reaction to stress, an important role is played by certain hormones(激素) released by the body. The UCLA research team suggests that the female tend-or-befriend response is also based on a hormone. This hormone, called oxytocin, has been studied in the context of childbirth, but now it is being studied for its role in the response of both men and women to stress. The principal investigator, Dr. Shelley E. Taylor, explained that "animals and people with high levels of oxytocin are calmer, more relaxed, more  social, and less anxious." While men also secrete(分泌）oxytocin, its effects are reduced by male hormones.
    In terms of everyday behavior, the UCLA study found that women are far more likely than men to seek social contact when they are feeling stressed. They may phone relatives or friends, or ask directions if they are lost.
    The study also showed how fathers and mothers responded differently when they came home to their family after a stressful day at work. The typical father wanted to be left alone to enjoy some peace and quiet. For a typical mother, coping with a bad day at work meant focusing her attention on her children and their needs.
    The differences in responding to stress may explain the fact that women have lower frequency of stress-related disorders such as high blood pressure or aggressive behavior. The tend-and-befriend regulatory(调节的) system may protect women against stress, and this may explain why women on average live longer than men.
    小题1:The UCLA study shows that in response to stress, men are more likely than women to _____ .
    A．turn to friends for helpB．solve a conflict calmly
    C．find an escape from realityD．seek comfort from children
    小题2:Which of the following is true about oxytocin according to the passage?
    A．Men have the same level of oxytocin as women do.
    B．Oxytocin used to be studied in both men and women.
    C．Both animals and people have high levels of oxytocin.
    D．Oxytocin has more of an effect on women than on men.
    小题3:What can be learned from the passage?
    A．Male hormones help build up the body's resistance to stress.
    B．In a family a mother cares more about children than a father does.
    C．Biological differences lead to different behavioral responses to stress.
    D．The UCLA study was designed to confirm previous research findings.
    小题4:Which of the following might be the best title of the passage?
    A．How men and women get over stress
    B．How men and women suffer from stress

    The $11 billion self-help industry is built on the idea that you should turn negative thoughts like “I never do anything right” into positive ones like “I can succeed”. But was positive thinking advocate Norman Vincent Peale right? Is there power in positive thinking?
    Researchers in Canada just published a study in the journal Psychological Science that says trying to get people to think more positively can actually have the opposite effect: it can simply highlight how unhappy they are.
    The study's authors, Joanne Wood and John Lee of the University of Waterloo and Elaine Perunovic of the University of New Brunswick, begin by citing (引证) older research showing that when people get feedback which they believe is overly positive, they actually feel worse, not better. If you tell your friend who is slow to learn that he has the potential of an Einstein, you’re just underlining his faults. In one 1990s experiment, a team including psychologist Joel Cooper of Princeton asked participants to write essays against funding for the disabled. When the essayists were later praised for their sympathy, they felt even worse about what they had written.
    In this experiment, Wood, Lee and Perunovic measured 68 students’ self-esteem (自尊). The participants were then asked to write down their thoughts and feelings for four minutes. Every 15 seconds, one group of students heard a bell. When it rang, they were supposed to tell themselves, “I am lovable.”
    Those with low self-esteem didn’t feel better after the forced self-affirmation (自我肯定). In fact, their moods turned significantly darker than those of members of the control group, who weren’t urged to think of positive thoughts.
    The paper provides support for newer forms of psychotherapy (心理治疗) that urge people to accept their negative thoughts and feelings rather than fight them. In the fighting, we not only often fail but can make things worse. Meditation (静思) techniques, in contrast, can teach people to put their shortcomings into a larger, more realistic viewpoint. Call it the power of negative thinking. 
    小题1:The first paragraph is written _________.
    A．to raise an argument about positive thinking
    B．to introduce the power of positive thinking
    C．to encourage people to have positive thoughts
    D．to introduce the $11 billion self-help industry
    小题2:According to the study of the Canadian researchers, _________.
    A．positive thinking is not as powerful as negative thinking
    B．encouraging positive thinking may actually discourage people
    C．happy people can think positively while unhappy people can’t
    D．getting people to think positively can strengthen their confidence
    小题3:What does the underlined sentence in Paragraph 3 mean?
    A．You are pointing out the mistakes he has made.
    B．You are reminding him that he is not intelligent.
    C．You are not taking his mistakes seriously enough.
    D．You are showing he has great potential in spite of faults.
    小题4:We can learn from the last paragraph that _________.
    A．negative feelings must be got rid of
    B．there’s no point in thinking positively
    C．it doesn’t make sense to think negatively
    D．negative thinking is not always negative
