    Recently the Barbican Museum in London held an exhibition called the Rain Room. During the time this exhibition was open, my twitter stream was filled with photos of people standing in the rain room, accompanied by the caption “rain room@ the barbican!” and a location attachment to prove that they were indeed in the rain room.

    This got me thinking. What were people actually saying by Tweeting about their visit? I think all they were doing was fulfilling the obligation that we have to share. Not sharing in the sense of treasuring a moment with people close to us, but sharing in the sense of “tell the world that I am doing a thing”.

    It’s not sharing; it’s showing off. When we log in to Facebook or Twitter we see an infinitely updating stream of people enjoying themselves. It’s not real life, because people only post about the good things whereas all the dull or deep stuff doesn’t get mentioned. But despite this obvious fact, it subconsciously makes us feel like everyone is having a better time than us.

    This is the curse of our age. We walk around with the tools to capture extensive data about our surroundings and transmit them in real-time to every friend we’ve made. We end up with a reduced understanding of reality because we’re more concerned about choosing a good Instagram filter(过滤器) for our meal than how it tastes.

    I don’t think that it’s inherently(内在的、固有的)wrong to want to keep the world updated about what you’re doing. But when you go through life robotically posting about everything you do, you’re not a human being. You’re just a prism that takes bits of light and sound and channels them into the cloud.

    The key thing to remember is that you are not enriching your experiences by sharing them online; you are detracting from them because all your efforts are focused on making the look attractive to other people. Once you stop seeing things through the eyes of the people following you on Twitter or Facebook or Instagram, you can make your experiences significant, because you were there and you saw the sights and smelled the smells and heard the sounds, not snapped a photo of it through a half-inch camera lens.

    28.What do we learn from the first two paragraphs?

    A. Rain Room exhibition received a large audience in London.

    B. Most of people feel obligated to share their experience with friends.

    C. Many people want to inform others of their experience by Tweeting.

    D. All people having gone to the Rain Room took pictures.

    29.It seems to the author that ___________.

    A. Facebook or Twitter is a good place where we share personal experience

    B. people seldom show depressing stuff on the social networking websites

    C. most people tend to show off that they are having a better time than others

    D. sharing experience on the social networking websites is not real life

    30.By talking of “a good Instagram filter for our meal” (Line 3-4, Para.4), the author wants to show _____.

    A. we are surrounded by various tools to capture our daily data

    B. we are more concerned about how our life seems to be to others

    C. we transmit our experience immediately to everybody we know

    D. we gain more extensive perception of reality with digital tools

        “Iris scan (虹膜扫描), please,” the bank’s computer voice tells you . You step up and the computer reads your eye, comparing it to the stored file it has of your iris. The images had better match—otherwise you won’t be able to get your money.

        Iris scanning and other technologies, such as fingerprint and voice scanning, have appeared in many science fiction movies in the past. Today, these advanced technologies are part of the real world. They are common at work, the bank, the airport, and your local prison. The iris scan, fingerprint scan, and voice scan are all examples of biometrics(生物测定学), a fast developing area of automatic personal identification technology. Basically, biometrics uses various ways to verify a persons identity, based on the individual’s unique characteristics, including fingerprints, voices, irises, body heat patterns, facial images, handprints, signatures and so on.

        Biometrics identification systems have a number of advantages over password systems. The primary advantage is that an individual has to be physically present in order to be identified. Another important advantage is that there are no passwords to remember, forget, lose or steal.

        The voice scan is the simplest and most affordable form of biometrics. It only requires a computer, a microphone and the correct software. The software records a subject’s voice and then compares it to a stored voice sample for identification purposes.

        For additional safety, fingerprint and handprint scans can also be employed. Fingerprint scans take the image of a fingerprint and compare it to a stored file of prints. Handprint scans identify the unique features of a hand.

        Iris scans currently give the highest level of accuracy among all the available biometrics systems. Another technology, full facial scans, is currently in use at border crossings and airports. Facial scanning equipment can actually track and identify moving faces within a crowd.

        The potential of biometrics is exciting and encouraging. With continued development, testing and application, current technologies will become even more effective in the future. Soon, the days of password and car keys will be gone. Just don’t leave home without your fingerprints!

    24. The first paragraph serves as a(n)         .

      A. conclusion   B. explanation   C. comment   D. example

    25. The underlined word “verify” in Paragraph 2 probably means “         ”.

      A. change   B. confirm   C. develop   D. protect

    26. Which is the most accurate form of biometrics?        

      A. The iris scan  B. The fingerprint scan  C. The voice scan D. The facial scan

    27. What is the author’s attitude towards the future of biometrics?        

      A. He is uncertain about it.    B. He feels doubtful about it.

      C. He feels hopeful about it.   D. He is worried about it.

    New research, attempting to throw light upon how male and female brains differ, has found that timing is everything. American Vanderbilt University researchers Stephen Camarata and Richard Woodcock discovered that females have a significant advantage over males in timed tests and tasks. The study involved more than 8,000 males and females ranging in age from 2 to 90 from across the US.

    “We found hardly any differences in overall intelligence. But we discovered that females performed better than men in time limited situations,” Camarata said, “It is very important for teachers to understand this difference in males and females when it comes to assigning work and tests.”

    Many males can do a better job without strict time limits, added Camarata.

    “Consider that many classroom activities, including testing, are directly or indirectly related to processing speed,the researchers wrote in their report. “The higher performance in females may contribute to a classroom culture that favors females, not because of teacher bias(偏见)but because of inherent(与生俱来的)differences in gender processing speeds.”

    The researchers found that males scored lower than females in all age groups in tests measuring processing speed. However, the study also found that males consistently outperformed females in some language abilities, such as identifying objects and knowing antonyms(反义词)and synonyms(同义词). The research contradicts the popular belief that girls develop all communication skills earlier than boys.

    The researchers found no significant overall intelligence differences between males and females in any age groups.

    “We believe there are fundamental differences in how male and female brains end up getting organized,” Camarata said, “Our next studies will give us some insight into where these processing differences are occurring.”

    46. The new research referred to in the passage is intended to ________

    A. find whether age has something to do with people's intelligence

    B. help teachers to assign work and arrange tests for students

    C. find what's the differences between male and female brains

    D. prove the differences in processing speed between males and females

    47. The underlined word “outperformed” in the fifth paragraph probably means “________”.

    A. to achieve better results than someone

    B. to perform worse in some aspect than someone

    C. to do something as well as someone

    D. to be not so good at something as someone

    48. People usually believe that ________.

    A. there're hardly any differences between males' and females' overall intelligence

    B. teachers favor girl students instead of boy students in schools

    C. girls develop their language skills earlier than boys

    D. females have a significant advantage over males in all subjects

    49. Which of the following statements is TRUE according to the passage?

    A. The researchers interviewed more than 8,000 males and females all over the world.

    B. Generally speaking, males can do better jobs with strict time limits than females.

    C. Females scored higher than males in any age groups in any situations.

    D. The differences in gender processing speeds occur when people are born.

    50. Which of the following can be inferred from the passage?

    A. The researchers will continue to study how the gender differences in timing occur.

    B. A female mathematician will make greater achievements than a male one.

    C. School teachers have already known about these processing differences before.

    D. If a girl has a higher processing speed than a boy, she must be more intelligent than him.

    Would you carry around an electronic ID,not in your pocket,but in your body? Does this idea scare you or make you feel safe?

    The first computer ID chip (芯片) that could be planted under a person's skin might be marketed very soon.

    Developed by Applied Digital,an American technology company based in Florida,the device (发明物) could meet the need for public security after the September 11 attacks.

    For airports,nuclear power plants (核电站) and other high security facilities,the immediate effects are obvious.

    The technology could help put an end to false ID cards,because it would be difficult to remove and copy a tiny computer chip.The chip is as small as a grain of rice.

    The technology would also allow satellites to track (追踪) a person's every movement and store medical records.

    These uses are already attracting interest for tasks like fighting against kidnappings(绑架),or helping with medical operations.

    But some people are afraid of the loss of privacy.

    "You always have to think about what the device could be used for tomorrow,"said Lee Tien,a senior privacy lawyer in the United States.

    "At first a device is used for applications we all agree are good,but then it slowly starts being used for more than it was intended,"he said.

    However,Applied Digital says it will soon apply for government permission for the device.It says that the first people to use the chip will be volunteers.

    Getting the implant (需移植的芯片) would go something like this:

    A person or company buys the chip from Applied Digital for about US $200.And the company encodes (编码) it with the desired information.

    The customer then takes the chip to their doctor,who can plant it with a large needle.

    The device has no power supply,rather it is activated (使活动,使运行) by a scanner (扫描仪) running across the skin above it.Without a scanner,the chip cannot be read.

    Even with the privacy concern,some are already eager to use the product.

    Jell Jacobs from Florida hopes to become the first buyer of the chip to store his medical records.Suffering from a serious illness,he wants to make sure doctors can help him quickly.

    Eight Latin American companies have also shown interests in the device.It could help to find any tourists who are kidnapped.

    25.The best title for the passage is      .

    A.Why Is the New ID Necessary                      B.Where to Buy the Chip

    C.An Advertisement for Chips                            D.Getting a New Kind of ID Under Your Skin

    26.Which of the following is true according to the text?

    A.In some airports and factories such device is already being used.

    B.The information on the chip can be read when it has its power supply.

    C.The technology could help put an end to false ID cards.

    D.The first computer ID chip has already come into the market.

    27.What is the advantage with the electronic ID according to the passage?

    A.It's cheap to buy and easy to get.

    B.With this people will have no fear of losing privacy.

    C.It can store people's medical records and help with medical operations.

    D.It is developed by Applied Digital in Florida.

    28.What can we learn about Jeff Jacobs?

    A.He's a worker in Applied Digital,a company in Florida.

    B.He's a doctor who helps plant tile chips on people.

    C.He fears if he uses the chip he will lose privacy.      

    D.He's suffering from a serious illness and wants to buy the chip.

        The science fiction type of entertainment is considered by most to be fathered by Jules Verne (AJourney to the Center of the Earth and Twenty Thousand Leagues Under the Sea) and H. G. Wells (The Time Machine and The War of the Worlds). Sci-Fi, as it is commonly shortened, is a fictional story in which science and technology have a significant influence on the characters and plot. Many such works are guesswork about what the future holds and how scientific findings and technological advances will shape humankind.

        Writing in the late 1800s, Jules Verne was remarkably successful in his 10 guesses about future technologies of air conditioning, automobiles, the Internet, television, and underwater, air, and space travel. Unbelievably, of all places from which to choose, Jules Verne guessed Tampa, Florida, USA as the launching site of the first project to the Moon, which was only 200 kilometers away from the actual 1969location at Cape Canaveral, Florida.

        One of the best-known science fiction books is Nineteen Eighty-Four by George Orwell. Published in1949, it was not meant as a prediction, but as a warning: Orwell was describing what he saw as the outcome of the ideas, trends, and emerging technologies of his time. Many invented terms from this novel have become common in everyday use, such as “big brother” and “doublethink”. Even the author’s name has been made into an adjective—Orwellian—and has become a warning expression of situations where privacy is lost and the individual has no power and is completely controlled by the government. Nineteen Eighty-Four was translated into sixty-five languages within five years of its publication, setting a record thatstill stands.

        What helps bring science fiction into being is usually a new discovery or innovation. The author creates an analysis of the potential influence and consequences and then wraps it in a pleasant story. For example, the beginning of space exploration was followed a few years later by the Star Trek television program and movie series. The science fiction author’s self-determined role is to search the world of future possibilities upon the road which we are traveling.

    32. From the first paragraph, we know that science fiction might be _________.

       A. a forecast of how a new discovery could influence mankind

       B. a brief review of the present drawbacks of technology

       C. a thoughtful look at the past and a prediction of the future

       D. an analysis of how a new technology could be used to harm human

    33. Which of the following best describes Nineteen Eighty-Four?

       A. A prediction of future technologies.     B. A warning of unfair and cruel ruling.

       C. The motive of scientific development.      D. An imaginary perfect world of freedom.

    34. From the passage we can learn that _________.

       A. H.G. Wells predicted the Internet in the late 1800s

       B. Nineteen Eighty-Four adopted some popular terms

       C. Star Trek movie series were based on space exploration

       D. Cape Canaveral was mentioned in Jules Verne’s fiction

    35. According to the author, what is the role of science fiction in our life?

       A. A reference of technology.         B. A moral compass.

       C. A record of science development.     D. A form of thinking about possibilities.

         Drinking two cups of hot chocolate a day may help old people keep brains healthy, a U.S. study said Wednesday.

         The study, published online in the American Academy of Neurology journal Neurology, involved 60 people with an average age of 73 who did not have dementia(痴呆)

         The participants drank two cups of hot cocoa per day for 30 days and did not consume any other chocolate during the study. They were also given tests of memory and thinking skills as well as ultrasounds(超音波) tests to measure the amount of blood flow to the brain.

         “We’re learning more about blood flow in the brain and its effect on thinking skills,” study author Farzaneh Sorond said in a statement. “As different areas of the brain need more energy to complete their tasks, they also need greater blood flow. This relationship may play an important role in diseases such as Alzheimer’s.”

         The researchers found that 18 of the 60 participants who had impaired blood flow at the start of the study saw an 8.3-percent improvement by the end of the study. There was no improvement for those who started out with regular blood flow.

         The people with impaired blood flow also improved their time on a test of working memory, with scores dropping from 167 seconds at the beginning of the study to 116 seconds in the end, the researchers said. There was no change in time for people with regular blood flow.

         A total of 24 of the participants also had magnetic resonance imaging(磁共振成像) scans of the brain to look for tiny areas of brain damage. The scans found that people with impaired blood flow were also more likely to have these areas of brain damage.

         “More work is needed to prove a link between cocoa, blood flow problems and cognitive (认知) decline,” said Paul Rosenberg, who wrote an editorial accompanying the study. “But this is an important first step that could guide future studies.”

    12. It can be learned from the passage that________.

      A. the study involved 73 people without dementia

      B. there was slight improvement for those participants

      C. Alzheimer’s may be connected with blood flow

      D. blood flow has little effect on thinking skills

    13. What does the underlined word in the 5th paragraph mean?

      A. Damaged---not as good as before           B. Improved---stronger than before

      C. Quicker---to some degree                 D. Normal---as good as before

    14. What can be inferred from the passage?

    A. It is uncertain that cocoa, blood flow problems and cognitive decline are connected.

      B. The better condition a person is in, the longer it will take to test the time of working memory.

      C. Cocoa will be in great demand in the future

      D. Drinking cocoa will be able to cure Alzheimer’s.

    15. What could be the title of the passage?

      A. Hot chocolate---a cure for dementia       B. Hot chocolate and blood flow

      C. A scientific discovery in medicine         D. Hot chocolate may help keep brain healthy

    Management Consultant Suzy Welch remembers the moment 14 years ago when her life “imploded(压破).” She was speaking to an auditorium full of insurance executives in Hawaii when she saw the faces of two of her children, then six and five, pressed against the glass door. She had parked them in a dance class, but they’d fled out to find her. She wrapped up her remarks and canceled the Q&A. “I was trying to please everyone but pleasing no-one,” she says, “I had to rethink the way I made my decisions.”

       Author of the bestselling Winning (written with husband Jack Welch, former head of GE), Suzy Welch, 49, has a new book, 10-10-10, that details the strategy she created after the tremendous decision-making moment. The mother of four explains: “When faced with a vital decision, ask yourself, how will my choice affect my life ten minutes from now? Ten months from now? Ten years from now?

       “Too often we decide something by avoiding the immediate ouch. But by looking at the middle and longer time frames as well as the short-term, we’re accessing our real values. My business trip is an example. Had I applied the strategy to it back then, I would have declined it. I had other work travel coming up. I was needed at home.

       “Many people have found ‘10-10-10’ thrilling. An entrepreneur moved forward with a new business plan but without the girlfriend, who didn’t share his goals. A mum of a troubled teen finally got him to a psychologist after putting it off. Often, in our most stressful moments, we make decisions by instinct only. Or we ask a friend for advice. Or we make no decision and suffer for it. We can live much more deliberately by taking control of choices and really understanding them.

       “Sure, there’s still room for spontaneity(自发的行为). But when you look at things from three distinct time frames and assess the consequences, never again will you say, ‘I have no idea why I made this decision.’”

    63. What did Suzy do to her two kids before addressing those executives 14 years ago?

       A. She left them in a car in a parking lot.

       B. She had a dance class together with the two kids.

       C. She fed the kids a lot of food and let them sleep.

       D. She just left them in a dance class.

    64. Which of the following is NOT true according to the passage?

       A. Suzy and her husband used to work in GE, and they achieved great success in business.

       B. Suzy and her husband had four children.

       C. Suzy believed that many people reached a decision by avoiding direct pains.

       D. Suzy failed to give up her work travel because she hadn’t had her great strategies then.

    65. Which of the following is probably one of the strategies in Suzy’s book?

       A. When doing business, you should learn to please everyone.

       B. Before making a vital decision, you should ask yourself instead of others.

       C. When carrying out a new plan, you’d better take your girlfriend.

       D. The assessment of consequences plays a vital role in decision-making.

    66. Suzy’s new book was mainly about _______.

       A. how to deal with numbers when doing business

       B. how to make decisions by following her strategies

       C. how to obtain more benefits in business111]

       D. how to make detailed strategies in business

    Blind imitation is self-destruction. To those who do not recognize their unique worth. Imitation appears attractive: to those who know their strength. Imitation is unacceptable. 

    In the early stages of skill or character development, imitation is helpful. When I first learned to cook, I used recipes and turned out some tasty dishes. But soon I grew bored. Why follow someone else's way of cooking when I could create my own? Imitating role models is like using training wheels on a child's bicycle; they help you get going, but once you find your own balance, you fly faster and farther without relying on them.

    In daily life, imitation can hurt us if we subconsciously (下意识地) hold poor role models. If, as a child, you observed people whose lives were bad, you may have accepted their fear and pain as normal and gone on to follow what they did. If you do not make strong choices for yourself, you will get the results of the weak choices of others. 

    In the field of entertainment, our culture glorifies celebrities. Those stars look great on screen. But when they step off screen, their personal lives may be disastrous. If you are going to follow someone, focus on their talent, not their bad character or unacceptable behaviors. 

    Blessed is the person willing to act on their sudden desire to create something unique. Think of the movies, books, teachers, and friends that have affected you most deeply. They touched you because their creations were motivated by inspiration, not desperation. The world is changed not by those who do what has been done before them, but by those who do what has been done inside them. Creative people have an endless resource of ideas. The problem a creator faces is not running out of material; it is what to do with the material knocking at the door of imagination. 

    Study your role models, accept the gifts they have given, and leave behind what does not server. Then you can say, “I stand on the shoulders of my ancestors’ tragedies and stories, and know that they are cheering me on.”

     33. To avoid the bad result of imitation, we should _____.

    A. forget daily fear and pain       B. ask others for decisions

    C. choose the right example        D. stay away from stars

    33. According to the author, the world moves on because of those who are _____.

    A. desperate to insurance others with their knowledge

    B. willing to accept others' ideas

    C. eager to discover what their ancestors did 

    D. ready to turn their original ideas into reality

    35. What is the author's purpose in writing this passage? 

    A. To highlight the importance of creatively. 

    B. To criticize the characters of role models. 

    C. To compare imitation with creation. 

    D. To explain the meaning of success.

    Before discussing different kinds of emotions,let us briefly talk about how researchers measure bodily processes and action or behavior,and how this relates to what we do in our daily lives when we observe emotions in others.

    Bodily processes can be directly measured by means of a polygraph.When a polygraph is skillfully used to compare how we react bodily with what we are saying,it is called a “lie detector”.Bodily processes can also be measured indirectly.This is what we do when we observe someone blushing (脸红).However,we are not always aware of what bodily processes respond to.

    Measuring action or behavior is the other way researchers assess the emotions.For example,one measure of fear of snakes is how close a person will go to the snake.Another procedure is to have a person tell how afraid he is,or how he feels.In this way,researchers have developed the socalled “fear thermometer” to assess a person's fear.In our everyday living,we do very much the same thing.Only not too systematically,we react to what a person does, what he says,how he says it,and how he looks.Is he smiling? Is his voice trembling? We put all this observations together to infer what a person is feeling.

    However,we do not always act as we feel.Sometimes we do things that we don't feel like doing.Sometimes we say we feel one way and then we act another.Actors,for example,successfully learn to “make believe” emotions,or learn to hide them.Thus we cannot always tell what a person is feeling by what he says or by what he does.

    29.Which of the following statements is NOT true? 

    A.We can never tell what a person is feeling.

    B.The “fear thermometer” is a way to measure how fearful a person is.

    C.Researchers can assess the emotions in some ways.

    D.People do not always know what bodily processes they respond to.

    30.The underlined word “assess” in the 3rd paragraph is close in meaning to ______.

    A.make                   B.measure               C.discuss                D.develop

    31.The writer uses the example of actors in order to argue that ______.

    A.it is rather easy to become successful actors                B.people do not always act as they feel

    C.we can never believe what other people say                D.actors are always telling lies

    32.The passage is mainly about ______.

    A.the way of assessing the emotion                         B.the usefulness of a “lie detector” 

    C.the functioning of different emotions                     D.the development of the “fear thermometer”

           As they migrate(迁移), butterflies and moths(飞蛾) 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 such little creatures at such great heights.

           To their surprise, though, the insects weren’t passive but active 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(导航) 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(抵消). 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.

    Larger brain size linked to longer life in deer

    The size of a female animals’ brain may determine whether they live longer and have more healthy offspring (后代), according to new research led by the University of Cambridge.

    The study, published in the Royal Society Open Science journal, shows that female red deer with larger brains live longer and have more surviving offspring than those with smaller brains. Brain size is passed down through the generations. This is the first extensive study of individual differences in brain size in wild mammals and draws on data comparing seven generations of deer.

    Across species of mammals, brain size varies widely. This is thought to be a consequence of specific differences in the benefits and costs of a larger brain. Mammals with larger brains may, for example, have greater cognitive abilities that enable them to adapt better to environmental changes or they may have longer lifespans (寿命) . But there may also be disadvantages: for instance, larger brains require more energy, so individuals that possess them may show reduced fertility (繁殖力).

    The researchers, based at the University of Cambridge’s Zoology Department and Edinburgh University’s Institute of Evolutionary Biology, wanted to test if they could find more direct genetic or non-genetic evidence of the costs and benefits of large brain size by comparing the longevity (长寿) and survival of individuals of the same species with different sized brains. Using the skulls of 1,314 wild red deer whose life histories and breeding success had been monitored in the course of a long-term study on the Isle of Rum, they found that females with larger endocranial volumes (脑腔容量) lived longer and produced more surviving offspring in the course of their lives.

    Lead author Dr Corina Logan, a Gates Cambridge Scholar, says, “The reasons for the association between brain size and longevity are not known, but other studies have suggested that larger brains are a consequence of the longer-lived species having longer developmental periods in which the brain can grow. These hypotheses (假设) were generated from cross-species correlations; however, testing such hypotheses requires investigations at the within-species level, which is what we did.”

    Dr Logan adds, “We found that some of the cross-species predictions about brain size held for female red deer, and that none of the predictions were supported in male red deer. This indicates that each sex likely experiences its own set of trade-offs (权衡,协调) with regard to brain size.” The study also showed that females’ relative endocranial volume is smaller than that of males, despite evidence of selection for larger brains in females.

    Professor Tim Clutton-Brock, who set up the Rum Red Deer study with Fiona Guinness in 1972 and initiated the work on brain size, points out, “The reason that this kind of study has not been conducted before is that it requires long term records of a large number of individuals across multiple generations and data of this kind are still rare in wild animals.”

    12.What does the new research about brain size reveal?

    A. Large-brain red deer tend to be more reproductive.

    B. Large-brain female deer survive small-brain male deer.

    C. Brain size causes individual differences in some mammals.

    D. Brain size has been increasing from generation to generation.

    13.For different species of mammals, brain size varies widely in that ______.

    A. mammals can develop different adaptive abilities

    B. a larger brain has its advantages and disadvantages

    C. different mammals are born with different lifespans

    D. brain size is affected by genetic or non-genetic factors

    14.What can we learn about the relation between brain size and longevity?

    A. The cause and effect needs to be further investigated.

    B. Brain size absolutely determines animals’ longevity.

    C. Longer-lived species allow brains to grow to a large size.

    D. The cross-species assumptions apply to red deer of both sexes.

    15.What can we infer from Professor Tim Clutton-Brock’s words?

    A. Researchers can’t possibly reach a conclusion about the reason.

    B. Researchers are not patient enough to keep long term records.

    C. Such research has been thoroughly conducted on wild animals before.

    D. Such research will witness great difficulty in the long-term process.

         If you' re considering a career in academia, or a job in a lab, previous lab experience is considered important. Most bioscience students in the UK get around 3-9 hours of lab time per week, but that' s not enough.

         There are a few places out there that offer paid internships (实习工作) in labs, but getting a work placement is tough. I'm a biochemistry student and have applied to several work placements, but in spite of my good grades, I was turned down by all of them. When I asked for personal feedback (反馈意见), I was usually told I lacked lab experience. Like many internships you need experience in order to get that experience.

         If you miss out on organized schemes, you can apply to individual labs requesting a summer work placement. But most labs don't reply. If you' re particularly lucky, a couple of academics get back to you to say either that they do not accept undergraduates (大学本科生), or that their lab has no more available spaces.

         Louis Freeland-Haynes, a Cambridge University biology student, who was able to find a summer work placement at a molecular biology (分子生物学)  lab  at  Edinburgh  University,  says,  "The experience gave me motivation and enthusiasm for the subject as most teaching labs restrict the amount of equipment you work with."

         But most of us are not as lucky. Things need to change. Science internships need to be accessible to a wide range of students, including those that do not have experience and do not have perfect grades. We need to give more people a chance to succeed in science—not just for the benefit of those students, but to progress scientific work and the benefits science brings to us all. Science students should be encouraged to experiment and learn through experiments. This can only be done if researchers and the scientific community can make lab internships more accessible.

    29. Why did the author fail to get a paid internship in a lab?

        A. No labs paid undergraduates.

        B. He had no personal feedback.

        C. He hardly had lab experience.

        D. His grades were not good enough.

    30. What can be inferred from Paragraph 3?

        A. Some individual labs accept undergraduates.

        B. Getting a summer work placement is difficult.

        C. Most individual labs will reply to the applicant.

        D. Undergraduates should adopt organized schemes.

    31. What does Louis Freeland-Haynes want to express in Paragraph 4?

        A. Some labs do offer paid internships.

        B. Getting a lab internship requires enthusiasm.

        C. Having a summer work placement in a lab is important.

        D. Teaching labs can greatly help students learn biology.

    32. Why has the author written the text?

        A. To tell students how to find paid internships.

        B. To encourage students to perform better at college.

        C. To  show undergraduates need more lab internships.

    D. To explain why undergraduates lack lab experience.

          A warm drink of milk before bed has long been the best choice for those wanting a good night's sleep. But now a study has found it really does help people nod offif it is milked from a cow at night.

          Researchers have discovered that "night milk" contains more melatonin (褪黑激素), which has been proven to help people feel sleepy and reduce anxiety.

          The study, by researchers from Seoul, South Korea, involved mice being fed with dried milk powder made from cows milked both during the day and at night.

          Those given night milk, which contained 10 times the amount of melatonin, were less active and less anxious than those fed with the milk collected during daytime, according to the study published in The Journal of Medicinal Food.

          Night milk quickened the start of sleep and caused the mice to sleep longer.

          While the effect of cows milk harvested at different time has not been tested on humans up to now, taking melatonin drugs has been suggested to those who are struggling to fall asleep at night.

          Previous studies have also indicated that milk can be excellent for helping sleep because of the calcium content, which helps people to relax.

          Milk is also sugar-free and addictive-free with nutritionists recommending skimmed milk as the best choice before bed as it is the least fattening. The more fat you take in before bedtime, the greater burden you will put on your body at night.

    25. According to the text, the mice fed with daytime milk

        A. started sleep more easily                     B. were more anxious

        C. were less active                            D. woke up later

    26. Which of the following is true of melatonin according to the text?

        A. It's been tested on mice for ten times.          B. It can make people more energetic.

        C. It exists in milk in great amount.              D. It's used in sleeping drugs.

    27. What can be a suitable title for the text?

        A. Night Milk and Sleep                       B. Fat, Sugar and Health

        C. An Experiment on Mice                         D. Milk Drinking and Health

    28. How does the author support the theme of the text?

        A. By giving examples.                          B. By stating arguments.

        C. By explaining statistical data.                   D. By providing research results.

    Scientists have found that the risk of getting cancer and heart disease is reduced when we take part in physical activityand now they've found cycling to work is one of the best activities to do this.

    The study linked using two wheels with a halving of the risk of cancer and heart disease.It also showed that walking had some benefits over sitting on public transport or taking the car.Cycling to work is already popular in many cities across the world.Some authorities have built cycle lanes.as well as providing secure places to lock them up.Some companies provide facilities for their employees to get changed and cleaned up when they arrive at work.It all makes good senseaccording to people surveyed in this study,regular cycling cut the risk of death from any cause by 41%,the incidence of cancer by 45% and heart disease by 46%.      

    Cycling to work is quicker and cheaper than using public transport.While going to the gym to lose a few pounds takes effort and commitment,cycling has just become part of the work routine.Clare Hyde from Cancer Research UK says,"This study helps to highlight the potential benefits of building activity into your everyday life."

    Of course,any exercise is good for you but it's thought that cycling is better than walking because the activity is longer and more intense.Dr.Jason Gill,from the University of Glasgow,said,"You need to get to work every day so if you build cycling into the day,it essentially takes willpower out of consideration."You don't need to wear skin-tight lycra clothes,as long as you wear the most important accessory,a helmet.

    28.The passage mainly focuses on       .

    A.the benefits of cycling                                B.the advantages of sports

    C.the changes of lifestyle                                          D.the prevention of cancer

    29.What can we learn from paragraph two?

    A.Walking is similar to sitting in a bus.             B.Cycling to work has gained popularity.

    C.Cycling to work causes more spending.                   D.City governments need more bicycles.

    30.What is the advantage of cycling to work compared to going to the gym?

    A.It is longer and more intense.                       B.It helps to lose more weight.

    C.It can be part of daily life.                                   D.It is quicker and cheaper.   

    31.According to Dr.Jason Gill,       .

        Researchers at the University of Kansas say that people can accurately judge 90 percent of a stranger's personality simply by looking at the person’s shoes.

        “Shoes convey a thin but useful piece of information about their wearer, the authors wrote in the new study published in the Journal of Research in Personality. “Shoes serve a practical purpose, and also serve as nonverbal cues(非语言暗示) with symbolic messages. People tend to pay attention to the shoes they and others wear.”

        Medical Daily notes that the detailed personality information detected in the study includes a person’s general age, gender, income, political ideas, and other personality, including someone’s emotional stability.

        Lead researcher Omri Gillath said the judgments were based on the style, cost, color and condition of someone’s shoes. In the study, 63 students from The University of Kansas researchers looked at pictures showing 208 different pairs of shoes worn by the study’s participants. Volunteers in the study were photographed in their most commonly worn shoes, and then filled out a personality questionnaire.

        Some of the results were expected: people with higher income most commonly wore expensive shoesand flashier footwear was typically worn by outgoing people.

        Howeversome results are funny and interesting. For example, “practical and functional” shoes were generally worn by more “agreeable” people, while ankle boots were more closely aligned with “aggressive” personality. The strangest of all may be that those who wore “uncomfortable looking” shoes tend to have “calm” personality.

        The researchers noted that some people would choose shoe styles to mask their actual personality informationbut researchers noted that volunteers were also likely to be unaware that their footwear choices were revealing deep insights into their personality.

    33. According to Paragraph 2, which of the following statements is true?

    A. The shoes people wear may reflect the information of the wearer.

    B. People would always look at strangers’ shoes with a practical purpose.

    C. Shoes are so funny and interesting that they attract people’s much attention.

    D. People pay attention to shoes in order to know the information of the shoes.

    34. According to the text, the researchers did the study by __________.

    A. doing casual interviews                  B. carrying out lab experiments

    C. analyzing the data from the participants     D. observing the participants

    35. The underlined part “aligned with” probably means “__________”.

       French surgeons have performed what they said on Wednesday was the world's first partial face transplant(移植)--- giving a new nose, chin and lips to a woman attacked by a dog.

       Specialists from two French hospitals carried out the operation on a 38-year-old woman on Sunday in the northern city of Amiens by taking the face from a brain-dead woman, who had hanged herself just hours before the operation. Her family agreed on the operation.

       “The patient is in an excellent state and the transplant looks normal,” the hospitals said in a brief statement after waiting three days to announce the pioneering surgery.

       The woman had been left without a nose and lips after the dog attacked her last May, and was unable to talk or chew properly. Such injuries are “extremely difficult, if not impossible” to repair using normal surgical techniques, the statement said.

        The statement did not say what the woman would look like when she had fully recovered, but medical experts said she was unlikely to resemble the woman who had been the source of her new face.

       The operation was led by Jean-Michel Dubernard, a specialist from a hospital in Lyon who has also carried out hand transplants.

       Skin transplants have long been used to treat burns and other injuries, but operations around the mouth and nose have been considered very difficult because of the area's high sensitivity(敏感) to foreign tissue.

        Teams in France, the United States and Britain had been developing techniques to make face transplants a reality

        There was a short-term risk for the patient if blood vessels became blocked, a medium-term danger of her body rejecting the new skin and a long-term possibility that the drugs used could cause cancers.

        Experts say that although such medical advances should be celebrated, the transplant had thrown up moral(道德的)and ethical(伦理的)issues. Little is known about the psychological effect of thee transplant.

    29. The best title for the passage would be ________.

      A. French Woman has First Partial Face Transplant    B. First Face Transplant Opens Debate

      C. Risks and Ethical Problems of a Face Transplant

      D. A Complete Face Transplant of a French Woman

    30. Why did the woman need such an operation?

     A. Her face had been bitten by a dog   B. Her face had been burnt in a fire.

     C. She was born especially ugly      D. She wanted to test such an operation.

    31. What can we learn about the operation?

    A. The woman had used the dead woman' s whole face.

    B. There has arisen(引起) a debate about the operation.

    C. The woman will suffer from psychological damage soon.

    D. Such transplants have been performed by doctors.

    32 . Which of the following is NOT one of the risks of the operation?

    A. Block of blood vessels.       B. Organ rejection

    C. Heart damage.              D. Side effect of the drugs

    A cookie can give one person a sugar rush while barely affecting another person, a new study finds, indicating that a food’s glycemic index(血糖指数)is in the eater.

    People’s blood sugar rises or falls differently even when they eat the exact same fruit, bread, deserts, pizza and many other foods, researchers report. That suggests that diets should be tailored to individuals’ personal characteristics.

    The researchers made the discovery after fitting 800 people with blood glucose (血糖)monitors for a week. The people ate standard breakfasts supplied by the researchers. Although the volunteers all ate the same food, their blood glucose levels after eating those foods varied dramatically. Characteristics and behaviors such as body mass index, sleep, exercise, blood pressure, cholesterol levels and the kinds of microbes(微生物) living in people’s intestines are associated with blood glucose responses to food, the researchers conclude.

    Those findings indicate that blood sugar spikes (血糖尖峰)after eating depend not only on what you eat, but how your system processes that food.

    A team led by a biologist created a computer algorithm(计算程序) that predicted how much a person’s blood sugar would rise or fall after eating a certain food. When testing on a new group of 100 people, the algorithm correctly predicted the response about 70 percent of the time.

    A third group of 26 participants were then given personalized meals. The computer algorithm analyzed each person and then picked diets for 12 of them. A nutritionist chose a “good” and “bad” diet for the remaining participants. Good diets were ones that minimized blood sugar spikes after eating. Bad diets sent blood sugar skyrocketing. The diets contained the same amount of calories. It turned out that foods on the “good” diet for one person were sometimes on another participant’s “bad” list.
