You may not use any of the words in the bankmore than once.As if you needed another reason to hate the gym, it now turns out that exercise can exhaust not only your muscles, but also your eyes. Fear not, however, for coffee can stimulate them again. During26 exercise, our muscles tire as they run out of fuel and build up waste products. Muscle performance can also be affected by a 27 called "central fatigue," in which an imbalance in the body's chemical messengers prevents the central nervous system from directing muscle movements 28 . It was not known , however , whether central fatigue might also affect motor systems not directly 29 in the exercise itself, such as those that move the eyes. To find out, researchers gave 11 volunteer cyclists a carbohydrate (碳水化合物的）30 either with a moderate dose of caffeine (咖啡因），which is known to stimulate the central nervous system ,or as a placebo (安慰剂）without, during 3 hours of 31 . After exercising ,the scientists tested the cyclists with eye-tracking cameras to see how well their brains could still 32 their visual system. The team found that exercise reduced the speed of rapid eye movements by about 8%, 33 their ability to capture new visual information. The caffeine, the equivalent of two strong cups of coffee, was 34 to reverse this effect, with some cyclists even displaying 35 eye movement speeds. So it might be a good idea to get someone else to drive you home after that marathon.A)cautiously B)commit C)controlD)cycling E)effectively F)increasedG)involved H)limited I)phenomenonJ)preventing K)sensitive L)slowingM)solution N)sufficient O)vigorousSection Ba passage wit ten statements attac e to it. Each statement contains Directions: In讥is section ,you are going to read·h h d·information given in one of the paragraphs. Identify the paragraph from which the information is derived.You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questionsby marking the corresponding letter on Answer Sheet 2.Team SpiritA)Teams have become the basic building blocks of organisations. Recruitment advertisements routinely call for"team players. " Business schools grade their students in part on their performance in group projects. Office managers knock down walls to encourage team building. Teams are as old as civilisation, of course: even Jesus had 12 co-workers. But a new report by Deloitte, "Global Human Capital Trends," based on a survey of more than 7,000 executives in over 130 countries, suggests that the fashion for teamwork has reached a new high.Almost half of those surveyed said their companies were either in the middle of restructuring or about to embark on (开始）it; and for the most part, restructuring meant putting more emphasis on teams.B)Companies are abandoning conventional functional departments and organising employees into cross-disciplinaryteams that focus on particular products, problems or customers. These teams are gaining more power to run their own affairs. They are also spending more time working with each other rather than reporting upwards. Deloitte argues that a new organisational form is on the rise: a network of teams is replacing the conventional hierarchy （等级体制）．C)The fashion for teams is driven by a sense that the old way of organising people is too rigid for both the modemmarketplace and the expectations of employees. Technological innovation places greater value on agility (灵活性）. John Chambers, chairman of Cisco Systems Inc. ,a worldwide leader in electronics products, says that "we compete against market transitions (过渡），not competitors. Product transitions used to take five or seven years; now they take one or two. "Digital technology also makes it easier for people to co-ordinate their activities without resorting to hierarchy. The "millennials" (千禧一代）who will soon make up half the workforce in rich countries were raised from nursery school onwards to work in groups.D)The fashion for teams is also spreading from the usual corporate suspects (such as GE and IBM) to some moreunusual ones. The Cleveland Clinic, a hospital operator, has reorganised its medical staff into teams to focus on particular treatment areas; consultants, nurses and others collaborate closely instead of being separated by speciality (专业）and rank. The US Army has gone the same way. In his book, Team of Teams ,General Stanley McChrystal describes how the army's hierarchicalstructure hindered its operations during the early stages of the Iraq war. His solution was to learn something from the rebels it was fighting: decentralising authority to self-organising teams.E)A good rule of thumb is that as soon as generals and hospital administrators jump on a management bandwagon（追随一种管理潮流），it is time to ask questions. Leigh Thompson of Kellogg School of Management in Illinois warns that, "Teams are not always the answer—teams may provide insight, creativity and knowledge ina way that a person working independently cannot; but teamwork may also lead to confusion, delay and poordecision-making." The late Richard Hackman of Harvard University once argued, "I have no question that when you have a team, the possibility exists that it will generate magic, producing something extraordinary. ..But don't count on it. "F)Hackman (who died in 2013) noted that teams are hindered by problems of co-ordination and motivation thatchip away at the benefits of collaboration. High-flyers (能干的人）who are forced to work in teams may be undervalued and free-riders empowered. Group-think may be unavoidable. In a study of旦Q teams of senior executives, he discovered that less than 10% of their supposed members agreed on who exactly was on the team.If it is hard enough to define a team's membership, agreeing on its purpose is harder still.G)Profound changes in the workforce are making teams trickier to manage. Teams work best if their members havea strong common culture. This is hard to achieve when, as is now the case in many big firms, a large proportionof staff are temporary contractors. Teamwork improves with time: America's National Transportation Safety Board found that 73% of the incidents in its civil-aviation database occurred on a crew's first day of flying together. However, as Amy Edmondson of Harvard points out, organisations increasingly use "team" as a verb rather than a noun: they form teams for specific purposes and then quickly disband them.H)The least that can be concluded from this research is that companies need to think harder about managing teams.They need to rid their minds of sentimentalism (感情用事）：the most successful teams have leaders who are able to set an overall direction and take immediate action. They need to keep teams small and focused: giving in to pressure to be more "inclusive" is a guarantee of dysfunction. Jeff Bezos, Amazon's boss, says that "If I see more than two pizzas for lunch, the team is too big. "They need to immunise teams against group-think: Hackman argued that the best ones contain "deviants" (离经叛道者）who are willing to do something that maybe upsetting to others.I) A new study of 12,000 workers in 17 countries by Steelcase, a furniture-maker which also does consulting, findsthat the best way to ensure employees are "engaged" is to give them more control over where and how they do their work—which may mean liberating them from having to do everything in collaboration with others.J)However, organisations need to learn something bigger than how to manage teams better: they need to be in the habit of asking themselves whether teams are the best tools for the job. Team-building skills are in short supply: Deloitte reports that only 12% of the executives they contacted feel they understand the way people work together in networks and only 21 %feel confident in their ability to build cross-functional teams. Loosely managed teams can become hotbeds of distraction—employees routinely complain that they can't get their work done because they are forced to spend too much time in meetings or compelled to work in noisy offices. Even in the age of openplan offices and social networks some work is best left to the individual.36.Successful team leaders know exactly where the team should go and are able to take prompt action.37.Decentralisation of authority was also found to be more effective in military operations.38.In many companies, the conventional form of organisation is giving way to a network of teams.39.Members of poorly managed teams are easily distracted from their work.40.Teamwork is most effective when team members share the same culture.41.According to a report by Deloitte, teamwork is becoming increasingly popular among companies.42.Some team members find it hard to agree on questions like membership and the team's purpose.43.Some scholars think teamwork may not always be reliable, despite its potential to work wonders.44.To ensure employees'commitment, it is advisable to give them more flexibility as to where and how they work.45.Product transitions take much less time now than in the past.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A) ,B), C) and D). You should decide on the best choice andmark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.Shoppers in the UK are spending less money on toilet paper to save money ,research has shown.Penny-pinching UK consumers choose cheaper products from discounters such as Aldi and Lidl rather than luxury alternatives.This has wiped 6% off the value of the soft tissue paper market in the UK. It has shrunk from£1. 19 billion in 2011 to£1. 12 billion in 2015, according to a new report from market research company Mintel. Furthermore, the future of the market looks far from rosy ,with sales expected to fall further to£1. 11 billion in 2016.In the last year alone ,despite an increase in the UK population and a subsequent rise in the number of households, sales of toilet paper fell by 2 % , with the average household reducing their toilet roll spending from£43 in 2014 to£41 in 2015.Overall, almost three in five people say they try to limit the让usage of paper—including facial tissue and kitchen roll—to save money. "Strength, softness and thickness remain the leading indicators of toilet paper quality, with just a small proportion of consumers preferring more luxurious alternatives, such as those with flower patterns or perfume, "said Mintel analyst Jack Duckett. " T hese extra features are deemed unnecessary by the majority of shoppers ,which probably reflects how these types of products are typically more expensive than regular toilet paper,even when on special offer."While consumers are spending less on toilet paper, they remain fussy—in theory at least—when it comes to paper quality. Top of Britons'toliet paper wish list is softness (57%) followed by strength (45%) and thickness (36%).One in 10 buyers rank toliet rolls made from recycled paper among their top considerations, highlighting how overall the environment is much less of a consideration for shoppers than product quality. In a challenge for manufacturers ,81 %of paper product users said they would consider buying recycled toilet tissue if it were comparable in quality to standard paper.46. The market sales of toilet paper have decreased because.A)Britons have cut their spending on itB)its prices have gone up over the yearsC)its quality has seen marked improvementD)Britons have developed the habit of saving4 7. What does the author think of the future of the tissue paper market in the UK?A)It will expand in time.B)It will remam gloomy.C)It will experience ups and downs.D)It will recover as population grows.48. What does Jack Duckett say about toilet paper?A)Special offers would promote its sales.B)Consumers are loyal to certain brands.C)Luxurious features add much to the price.D)Consumers have a variety to choose from.49. What do we learn about Britons concerning toilet paper?A)They are particular about the quality of toilet paper.B)They emphasize the strength of toilet paper the most.C)They prefer cheap toilet paper to recycled toilet paper.D)They reject using toilet paper with unnecessary features.50. What can we infer from the last paragraph?A)More and more Britons buy recycled toilet paper to protect the environment.B)Toilet paper manufacturers are facing a great challenge in promoting its sales.C)Toilet paper manufacturers compete with one another to improve product quality.D)Environmental protection is not much of a concern when Britons buy toilet paper.Passage TwoQuestions 51 to 55 are based on the following passage."One of the reasons I find this topic very interesting is because my mom was a smoker when I was younger, " says Lindson-Hawley, who studies tobacco and health at the University of Oxford.By studying about 700 adult smokers ,she found out that her mom quit the right way—by stopping abruptly and completely.In her study, participants were randomly (随机地）assigned to two groups. One had to quit abruptly on a given day, going from about a pack a day to zero. The other cut down gradually over the course of two weeks. People in both groups used nicotine (尼古丁）patches before they quit ,in addition to a second form of nicotine replacement , like gum or spray. They also had talk therapy with a nurse before and after quit day.Six months out, more people who had quit abruptly had stuck with it—more than one-fifth of them, comparedto about one-seventh in the other group. Although these numbers appear low, it is much higher than if people try without support.And the quit rates were particularly convincing given that before the study started, most of the people had said they'd rather cut down gradually before quitting. "If you're training for a marathon, you wouldn't expect to turn up and just be able to run it. And I think people see that for smoking as well. They think,'Well, if I gradually reduce, it's like practice,"'says Lindson-Hawley. But that wasn't the case. Instead of giving people practice, the gradual reduction likely gave them cravi ngs (瘾）and withdrawal symptoms before they even reached quit day, which could be why fewer people in that group actually made it to that point. "Regardless of your stated preference, if you're ready to quit, quitting abruptly is more effective," says Dr. Gabriela Ferre让a." W hen you can quote a specific number like a fifth of the patients were able to quit, that's compelling. It gives them the encouragement, I think, to really go for it," Ferreira says.People rarely manage to quit the first time they try. But at least, she says, they can maximize the odds of success.51. What does Lindson-Hawley say about her mother?A)She quit smoking with her daughter's help.B)She succeeded in quitting smoking abruptly.C)She was also a researcher of tobacco and health.D)She studied the smoking patterns of adult smokers.52. What kind of support did smokers receive to quit smoking in Lindson-Hawley's study?A)They were given physical training.B)They were looked after by physicians.C)They were encouraged by psychologists.D)They were offered nicotine replacements.53.How does Dr. Gabriela Ferreira view the result of Lindson-Hawley's experiment?A)It is idealized.B)It is unexpected.C)It is encouraging.D)It is misleading.54.The idea of "a marathon" (Line 2, Para. 5) illustrates the popular belief that quitting smoking.A)is something few can accomplish B)needs some practice firstC)requires a lot of patience D)is a challenge at the beginning55. What happens when people try to quit smoking gradually?A)They find it even more difficult.B)They are simply unable to make it.C)They show fewer withdrawal symptoms.D)They feel much less pain in the process.Part IV Translation (30 minutes) Directions : 的r this part, you are allowed 30 minutes to translate a passage f rom Chinese into English.

At the speed of only 30 miles per hour it is the same as falling from a third-floor windows. Wearing a seat belt saves lives; it reduces your chance of death or serious injury by more than half.Therefore drivers or front seat passengers over 14 in most vehicles must wear a seat belt. If you do not, you could be fined up to ￡50. it will not be up to the drivers to make sure you wear your belt. But it will be the driver’s responsibility to make sure that children under 14 do not ride in the front unless they are wearing a seat belt of some kind.However, you do not have to wear a seat belt if you reversing your vehicle; or you are making a local delivery or collection using a special vehicle; or if you have a valid medical certificate which excuses you from wearing it. Make sure these circumstances apply to you before you decide not to wear you seat belt. Remember you may be taken to court for not doing so, and you may be fined if you cannot prove to the court that you have been excused from wearing it.21.

This is the research finding of a team of Japanese doctors, who say that most of our brains are not getting enough exercise—and as a result, we are ageing unnecessarily soon.Professor Taiju Matsuzawa wanted to find out why otherwise healthy farmers in northern Japan appeared to be losing their ability to think and reason at a relatively early age, and how the process of ageing could be slowed down.With a team of colleagues at Tokyo National University, he set about measuring brain volumes of a thousand people of different ages and varying occupations.Computer technology enabled the researchers to obtain precise measurements of the volume of the front and side sections of the brain, which relate to intellect (智能) and emotion, and determine the human character. (The rear section of the brain, which controls functions like eating and breathing, does not contract with age, and one can continue living without intellectual or emotional faculties.)Contraction of front and side parts—as cells die off—was observed I some subjects in their thirties, but it was still not evident in some sixty- and seventy-year-olds.Matsuzawa concluded from his tests that there is a simple remedy to the contraction normally associated with age—using the head.The findings show in general terms that contraction of the brain begins sooner in people in the country than in the towns. Those least at risk, says Matsuzawa, are lawyers, followed by university professors and doctors. White collar workers doing routine work in government offices are, however, as likely to have shrinking brains as the farm worker, bus driver and shop assistant.Matsuzawa’s findings show that thinking can prevent the brain from shrinking. Blood must circulate properly in the head to supply the fresh oxygen the brain cells need. “The best way to maintain good blood circulation is through using the brain,” he says, “Think hard and engage in conversation. Don’t rely on pocket calculators.”26. The team of doctors wanted to find out ________.A) why certain people age sooner than othersB) how to make people live longerC) the size of certain people’s brainsD) which people are most intelligent27. On what are their research findings based?A) A survey of farmers in northern Japan.B) Tests performed on a thousand old people.C) The study of brain volumes of different peopleD) The latest development of computer technology.28. The doctor’s test show that ________.A) our brains shrink as we grow olderB) the front section of the brain does not shrinkC) sixty-year-olds have the better brains than thirty-year-oldsD) some people’s brains have contracted more than other people’s29.

According to the passage, which people seem to age slower than the others?A) Lawyers.B) Farmers.C) Clerks.D) Shop assistants.Passage ThreeQuestions 31 to 35 are based on the following passage.On June 17, 1744, the officials from Maryland and Virginia held a talk with the Indians of the Six Nations. The Indians were invited to send boys to William and Mary College. In a letter the next day the refused the offer as follows:We know that you have a high opinion of the kind of learning taught in your colleges, and that the costs of living of our young men, while with you, would be very expensive to you. We are convinced that you mean to do us good by your proposal; and we thank you heartily. But you must know that different nations have different ways of looking at things, and you will therefore not be offended if your ideas of this kind of education happen not t be the same as yours. We have had some experience of it. Several of our young people were formerly brought up at the colleges of the northern provinces: they were taught all your sciences; but, when they came back to us, they were bad runners, ignorant of every means of living in the woods…they were totally good for nothing.We are, however, not the less obliged by your kind offer, though we refuse to accept it; and, to show our grateful sense of it, if the gentlemen of Virginia will send up a dozenof their sons, we will take care of their education, teach them in all we know, and make men of them.31. The passage is about ________.A) the talk between the Indians and the officialsB) the colleges of northern provincesC) the educational values of the IndiansD) the problems of the Americans in the mid-eighteenth century32. The Indians’ chief purpose in writing the letter seems to be to ________.A) politely refuse a friendly offerB) express their opinion on equal treatmentC) show their prideD) describe Indian customs33. According to the letter, the Indians believed that ________.A) it would be better for their boys to receive some schoolingB) they were being insulted by the offerC) they knew more about science than the officialsD) they had a better way of educating young men34. Different from the officials’ view of education, the Indians though ________.A) young women should also be educatedB) they had different goals of educationC) they taught different branches of scienceD) they should teach the sons of the officials first35. The tone of the letter as a whole is best described as ________.A) angryB) pleasantC) politeD) inquiringPassage FourQuestions 36 to 40 are based on the following passage.In what now seems like the prehistoric times of computer history, the earth’s postwar era, there was quite a wide-spread concern that computers would take over the world from man one day. Already today, less than forty years later, as computers arerelieving us of more and more of the routine tasks in business and in our personal lives, we are faced with a less dramatic but also less foreseen problem. People tend to be over-trusting of computers and are reluctant to challenge their authority. Indeed, they behave as if they were hardly aware that wrong buttons may be pushed, or that a computer may simply malfunction (失误).Obviously, there would be no point in investing in a computer if you had to check all its answers, but people should also rely on their own internal computers and check the machine when they have the feeling that something has gone wrong.Questioning and routine double-checks must continue to be as much a part of good business as they were in pre-computer days. Maybe each computer should come with the warning: for all the help this computer may provide, it should not be seen as a substitute for fundamental thinking and reasoning skills.36. What is the main purpose of this passage?A) To look back to the early days of computers.B) To explain what technical problems may occur with computers.C) To discourage unnecessary investment in computers.D) To warn against a mentally lazy attitude towards computers.37. According to the passage, the initial concern about computers was that they might________.A) change our personal livesB) take control of the worldC) create unforeseen problemsD) affect our businesses38. The passage recommends those dealing with computers to ________.A) be reasonably doubtful about themB) check all their answersC) substitute them for basic thinkingD) use them for business purposes only39. The passage suggests that the present-day problem with regard to computers is________.A) challengingB) psychologicalC) dramaticD) fundamental40. It can be inferred from the passage that the author would disapprove of ________.A) investment in computersB) the use of on e’s internal computerC) double-check on computersD) complete dependence on computers for decision-makingPart III Vocabulary and Structure (20 minutes)Directions: There are 30 incomplete sentences in this part.

Despite having as brain no bigger than the 28 of your index finger, pigeons have a very impressive 29 memory. Recently it was shown that they could be trained to be as accurate as humans at detecting breast cancer in images.Rats are often 30 with spreading disease rather than 31 it, but this long-tailed画mal is highly 32 —. Inside a rat's nose are up to 1 ,000 different types of olfactoryreceptors (嗅觉感受器），whereas humans only have 100 to 200 types. This gives rats the ability to detect 33 smells. As a result, some rats are being put to work to detect TB (肺结核）. When the rats detect the smell, they stop and rub their legs to 34 a sample is infected.Traditionally, a hundred samples would take lab technicians more than two days to 35 , but for a rat it takes less than 20 minutes. This rat detection method doesn't rely on specialist equipment. It is also more accurate—the rats are able to find more TB infections and, therefore, save more lives.Section B A)associatedD)nuisanceG)prohibitingJ)speci fyM)tipB)examineE)peakH)sensitiveK)superiorN)treatedC)indicateF)preventingI)slightL)suspiciousO)visualDirections: In this section, you are going to read a passage with ten statements attached to it.

So it may seem rather strange that I have returned to college to finish thedegree I left undone some four decades ago. I am making my way through Columbia University, surrounded by students who quickly supply the verbal answer while I am still processing the question.B)Since there is no way for me to avoid exams ,I am currently questioning what kind are the most taxing and ultimately beneficial. I have already sweated through numerous in-class midterms and finals, and now I have a professor who issues take-home ones. I was excited when I learned this, figuring I had a full week to do the research, read the texts, and write it all up. In fact, I was still rewriting my midterm the morning it was due. Tosay I had lost the thread is putting it mildly.C)As I was suffering through my week of anxiety, overthinking the material and guessing my grasp of it, I didsome of my own polling among students and professors. David Eisenbach, who teaches a popular class on U.S.presidents at Columbia, prefers the in-class variety. He believes students ultimately learn more and encourages them to form study groups. "That way they socialize over history outside the class, which wouldn't happen without the pressure of an in-class exam," he explained. "Furthermore, in-class exams force students to learn how to perform under pressure , an essential work skill. "D)He also says there is less chance of cheating with the in-class variety. In 2012, 125 students at Harvard werecaught up in a scandal when it was discovered they had cheated on a take-home exam for a class entitled "Introduction To Congress. "Some colleges have what they call an "honor code," though if you are smart enough to get into these schools, you are either smart enough to get around any codes or hopefully, too ethical to consider doing so. As I sat blocked and clueless for two solid days, I momentarily wondered if I couldn't just call an expert on the subject matter which I was tackling, or someone who took the class previously, to get me go m g.E)Following the Harvard scandal, Mary Miller, the former dean of students at Yale, made an impassioned appealto her school's professors to refrain from take-home exams. "Students risk health and well being, as well as performance in other end-of-term work, when faculty offers take-home exams without clear, time-limited boundaries," she told me. "Research now shows that regular quizzes, short essays, and other assignments over the course of a term better enhance learning and retention. "F)Most college professors agree the kind of exam they choose largely depends on the subject. A quantitative-basedone, for example, is unlikely to be sent home, where one could ask their older brothers and sisters to help.Vocational-type classes, such as computer science or journalism, on the other hand, are often more researchoriented and lend themselves to take-home testing. Chris Koch, who teaches "History of Broadcast Journalism"at Montgomery Community College in Rockville, Maryland, points out that reporting is about investigation rather than the memorization of minute details. "In my field, it's not what you know—it's what you know how to find out, "says Koch. "There is way too much information, and more coming all the time, for anyone to remember.I want my students to search out the answers to questions by using all the resources available to them. "G)Students'test-form preferences vary, too, often depending on the subject and course difficulty. "I prefer takehome essays because it is then really about the writing, so you have time to edit and do more research, "says Elizabeth Dresser, a junior at Barnard. Then there is the stress factor. Francesca Haass, a senior at Middlebury, says, "I find the in-class ones are more stressful in the short term, but there is immediate relief as you swallow information like mad, and then you get to forget it all. Take-homes require thoughtful engagement which can lead to longer term stress as there is never a moment when the time is up. "Meanwhile, Olivia Rubin, a sophomore at Emory, says she hardly even considers take-homes true exams. "If you understand the material and have the ability to articulate (说出）your thoughts, they should be a breeze. "H)How students ultimately handle tests may depend on their personal test-taking abilities. There are people whoalways wait until the last minute, and make it much harder than it needs to be. And then there are those who, not knowing what questions are coming at them , and having no resources to refer to , can freeze. And then there are we rare folks who fit both those descriptions.I)Yes , my advanced age must factor into the equation (等式），in part because of my inability to access the information as quickly. As another returning student at Columbia, Kate Marber, told me, "We are learning not only all this information, but essentially how to learn again. Our fellow students have just come out of high school. A lot has changed since we were last in school. "J)If nothing else, the situation has given my college son and me something to share. When I asked his opinion on this matter, he responded, "I like in-class exams because the time is already reserved, as opposed to using my free time at home to work on a test, " he responded. It seems to me that a compromise would be receiving the exam questions a day or two in advance, and then doing the actual test in class with the ticking clock overhead. K)Better yet, how about what one Hunter College professor reportedly did recently for her final exam: She encouraged the class not to stress or even study, promising that, "It is going to be a piece of cake. " When the students came in, sharpened pencils in hand, there was not a blue book in sight. Rather, they saw a large chocolate cake and they each were given a slice.36.Elderly students find it hard to keep up with the rapid changes in education.37.Some believe take-home exams may affect students'performance in other courses.38.Certain professors believe in-class exams are ultimately more helpful to students.39.In-class exams are believed to discourage cheating in exams.40.The author was happy to learn she could do some exams at home.41.Students who put off their work until the last moment often find the exams more difficult than they actually are.42.Different students may prefer different types of exams.43.Most professors agree whether to give an in-class or a take-home exam depends on the type of course beingtaught.44.The author dropped out of college some forty years ago.45.Some students think take-home exams will eat up their free time.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A) ,B), C) and D). You should decide on the best choice andmark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.That people often experience trouble sleeping in a different bed in unfamiliar surroundings is a phenomenon known as the "fast-night" effect. If a person stays in the same room the following night they tend to sleep more soundly. Yuka Sasaki and her colleagues at Brown University set out to investigate the origins of this effect.Dr. Sasaki knew the first-night effect probably has something to do with how humans evolved. The puzzle was what benefit would be gained from it when performance might be affected the following day. She also knew from previous work conducted on birds and dolphins that these画mals put half of their brains to sleep at a time so that they can rest while remaining alert enough to avoid predators (捕食者）. This led her to wonder if people might be doing the same thing. To take a closer look, her team studied 35 healthy people as they slept in the unfamiliar envirorunent of the university's Department of Psychological Sciences. The participants each slept in the department for two nights and were carefully monitored with techniques that looked at the activity of their brains. Dr. Sasaki found ,as expected ,the participants slept less well on their first night than they did on their second ,taking more than twice as long to fall asleep and sleeping less overall. During deep sleep, the participants'brains behaved in a similar manner seen in birds and dolphins. On the first night only, the left hemispheres (半球）of their brains did not sleep nearly as deeply as their right hemispheres did.Curious if the left hemispheres were indeed remaining awake to process information detected in the surrounding envirorunent, Dr. Sasaki re-ran the experiment while presenting the sleeping participants with a mix of regularlytimed beeps (峰鸣声）of the same tone and irregular beeps of a different tone during the night. She worked out that , if the left hemisphere was staying alert to keep guard in a strange environment, then it would react to the irregular beeps by stirring people from sleep and would ignore the regularly timed ones. This is precisely what she found.46. W hat did researchers find puzzling about the first-night effect?A) To what extent it can trouble people.B) What role it has played in evolution.C) What circumstances may trigger it.D) In what way it can be beneficial.47. W hat do we learn about Dr. Yuka Sasaki doing her research?A)She found birds and dolphins remain alert while asleep.B)She found birds and dolphins sleep in much the same way.C)She got some idea from previous studies on birds and dolphins.D)She conducted studies on birds'and dolphins'sleeping patterns.48. W hat did Dr. Sasaki do when she first did her experiment?A)She monitored the brain activity of participants sleeping in a new envirorunent.B)She recruited 35 participants from her Department of Psychological Sciences.C)She studied the differences between the two sides of participants'brains.D)She tested her findings about birds and dolphins on human subjects.49. W hat did Dr. Sasaki do when re-running her experiment?A)She analyzed the negative effect of irregular tones on brains.B)She recorded participants'adaptation to changed environment.C)She exposed her participants to two different stimuli.D)She compared the responses of different participants.50. W hat did Dr. Sasaki find about the participants in her experiment?A)They tended to enjoy certain tones more than others.B) They tended to perceive irregular beeps as a threat.C) They felt sleepy when exposed to regular beeps.D)They differed in their tolerance of irregular tones.Passage TwoQuestions 51 to 55 are based on the following passage.It's time to reevaluate how women handle conflict at work. Being overworked or over-committed at home and on the job will not get you where you want to be in life. It will only slow you down and hinder your career goals.Did you know women are more likely than men to feel exhausted? Nearly twice as many women than men ages 18-44 reported feeling "very tired" or "exhausted", according to a recent study.This may not be surprising given that this is the age range when women have children. It's also the age range when many women are trying to balance careers and home. One reason women may feel exhausted is that they have a hard time saying "no." Women want to be able to do it all—volunteer for school parties or cook delicious meals— and so their answer to any request is often "Yes, I can. "Women struggle to say " n o" in the workplace for similar reasons ,including the desire to be liked by their colleagues. Unfortunately, this inability to say "no" may be hurting women's health as well as their career.At the workplace, men use conflict as a way to position themselves, while women often avoid conflict or strive to be the peacemaker, because they don't want to be viewed as aggressive or disruptive at work. For example,there's a problem that needs to be addressed immediately, resulting in a dispute over who should be the one to fix it. Men are more likely to face that dispute from the perspective of what benefits them most, whereas women may approach the same dispute from the perspective of what's the easiest and quickest way to resolve the problem—even if that means doing the boring work themselves.This difference in handling conflict could be the deciding factor on who gets promoted to a leadership position and who does not. Leaders have to be able to delegate and manage resources wisely—including staff expertise. Shouldering more of the workload may not earn you that promotion. Instead, it may highlight your inability to delegate effectively.51.What does the author say is the problem with women?A)They are often unclear about the career goals to reach.B) They are usually more committed at home than on the job.C) They tend to be over-optimistic about how far they could go.D) They tend to push themselves beyond the limits of their ability.52.

You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.A rat or pigeon might not be the obvious choice to tend to someone who is sick, but these creatures have some 26 skills that could help the treatment of human diseases.Pigeons are often seen as dirty birds and an urban 27 , but they are just the latest in a long line of animals that have been found to have abilities to help humans. Despite having a brain no bigger than the 28 of your index finger, pigeons have a very impressive 29__ memory. Recently it was shown that they could be trained to be as accurate as humans at detecting breast cancer in images.Rats are often 30 with spreading disease rather than 31 it, but this long-tailed animal is highly 32 . Inside a rat's nose are up to 1,000 different types of olfactory receptors (嗅觉感受器), whereas humans only have 100 to 200 types. This gives rats the ability to detect __33 smells. As a result, some rats are being put to work to detect TB(肺结核). When the rats detect the smell, they stop and rub their legs to 34 a sample is infected.Traditionally, a hundred samples would take lab technicians more than two days to 35 , but for a rat it takes less than 20 minutes. This rat detection methoddoesn't rely on specialist equipment. It is also more accurate — the rats are able to find more TB infections and, therefore, save more lives.Section BDirections: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.Do In-Class Exams Make Students Study Harder?Research suggests they may study more broadly for the unexpected rather than search for answers.[A] I have always been a poor test-taker. So it may seem rather strange that I have returned to college to finish the degree I left undone some four decades ago.I am making my way through Columbia University, surrounded by students who quickly supply the verbal answer while I am still processing the question.[B] Since there is no way for me to avoid exams, I am currently questioning what kind are the most taxing and ultimately beneficial. I have already sweated through numerous in-class midterms and finals, and now I have a professor who issues take-home ones. I was excited when I learned this, figuring I had a full week to do the research, read the texts, and write it all up. In fact, I was still rewriting my midterm the morning it was due. To say I had lost the thread is putting it mildly.[C] As I was suffering through my week of anxiety, overthinking the material and guessing my grasp of it, I did some of my own polling among students and professors. David Eisenbach, who teaches a popular class on U.S. presidents at Columbia, prefers the in-class variety. He believes students ultimately learn more and encourages them to form study groups. “That way they socialize over history outside the class, whichwouldn’t happen without the pressure of an in-class exam,” he explained, “Furthermore, in-class exams force students to learn how to perform under pressure, and essential work skill.”[D] He also says there is less chance of cheating with the in-class variety. In 2012, 125 students at Harvard were caught up in a scandal when it was discovered they had cheated on a take-home exam for a class entitled “Introduction To Congress.”Some colleges have what they call an “honor code,” though if you are smart enough to get into these schools, you are either smart enough to get around any codes or hopefully, too ethical to consider doing so. As I sat blocked and clueless for two solid days, I momentarily wondered if I couldn’t just call an expert on the subject matter which I was tackling, or someone who took the class previously, to get me going.[E] Following the Harvard scandal, Mary Miller, the former dean of students at Yale, made an impassioned appeal to her school’s professors to refrain from take-hone exams. “Students risk health and well being, as well as performance in other end-of-term work, when faculty offers take-home exams without clear, time-limited boundaries,” she told me. “Research now shows that regular quizzes, short essays, and other assignments over the course of a term better enhance learning and retention.”[F] Most college professors agree the kind of exam they choose largely depends on the subject. A quantitative-based one, for example, is unlikely to be sent home, where one could ask their older brothers and sisters to help. Vocational-type classes, such as computer science or journalism, on the other hand, are often more research-oriented and lend themselves to take-home testing. Chris Koch, who teaches “History of Broadcast Journalism” at Montgomery Community College in Rockville, Maryland, points out that reporting is about investigation rather than the memorization of minute details. “In my field, it’s not what you know—it’s what you know how to find out,” says Koch. “There is way too much information, and more coming all the time, for anyone to remember. I want my students to search out the answers to questions by using all the resources available to them.[G] Students’ test-form preferences vary, too, often depending on the subject and course difficulty. “I prefer take-home essays because it is then really about the writing, so you have time to edit and do more research,” says Elizabeth Dresser, a junior at Barnard. Then there is the stress factor. Francesca Haass, a senior at Middlebury, says, “I find the in-class ones are more stressful in the short term, but there is immediate relief as you swallow information like mad, and then you getto forget it all. Take-homes require thoughtful engagement which can lead to longer term stress as there is never a moment when the time is up.” Meanwhile, Olivia Rubin, a sophomore at Emory, says she hardly even considers take-homes true exams. “If you understand the material and have the ability to articulate (说出) your thoughts, they should be a breeze.”[H] How students ultimately handle stress may depend on their personaltest-taking abilities. There are people who always wait until the last minute, and make it much harder than it needs to be. And then there those who, not knowing what questions are coming at them, and having no resources to refer to, can freeze. And then there are we rare folks who fit both those descriptions.[I] Yes, my advanced age must factor into the equation (等式), in part because of my inability toaccess the information as quickly. As another returning student at Columbia, Kate Marber, toldme, “We are learning not only all this information, but essentially how to learn again. Ourfellow students have just come out of high school. A lot has changed since we were last inschool.”[J] If nothing else, the situation has given my college son and me something to share, When Iasked his opinion on this matter, he responded, “I like in-class exams because the time isalready reserved, as opposed to using my free time at home to work on a test,” he responded.It seems to me that a compromise would be receiving the exam questions a day or two inadvance, and then doing the actual test in class the ticking clock overhead.[K] Better yet, how about what one Hunter College professor reportedly did recently for her finalexam: She encouraged the class not to stress or even study, promising that, “It is going to be apiece of cake.” When the students came in, sharpened pencils in hand, there was not a bluebook in sight. Rather, they saw a large chocolate cake and they each were given a slice.36. Elderly students find it hard to keep up with the rapid changes in education.37. Some believe take-home exams may affect students' performance in other courses.38. Certain professors believe in-class exams are ultimately more helpful to students.39. In-class exams are believed to discourage cheating in exams.40. The author was happy to learn she could do some exams at home.41. Students who put off their work until the last moment often find the exams more difficult thanthey actually are.42. Different students may prefer different types of exams.43. Most professors agree whether to give an in-class or a take-home exam depends on type ofcourse being taught.44. The author dropped out of college some forty years ago.45. Some students think take-home exams will eat up their free time.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 and 50 are based on the following passage.That people often experience trouble sleeping in a different bed in unfamiliar surroundings is a phenomenon known as the “first-night” effect. If a person stays in the same room the following night they tend to sleep more soundly. Yuka Sasaki and her colleagues at Brown University set out to investigate the origins of this effect.Dr. Sasaki knew the first-night effect probably has something to do with how humans evolved. The puzzle was what benefit would be gained from it when performance might be affected the following day. She also knew from previous work conducted on birds and dolphins that these animals put half of their brains to sleep at a time so that they can rest while remaining alert enough to avoid predators (捕食者). This led her to wonder if people might be doing the same thing. To take a closer look, her team studied 35 healthy people as they slept in the unfamiliar environment of the university’s Department of Psychological Sciences. The participants each slept in the department for two nights and were carefully monitored with techniques that looked at the activity of their brains. Dr. Sasaki found, as expected, theparticipants slept less well on their first night than they did on their second, taking more than twice as long to fall asleep and sleeping less overall. During deep sleep, the participants’ brains behaved in a similar manner seen in birds and dolphins. On the first night only, the left hemispheres (半球) of their brains did not sleep nearly as deeply as their right hemispheres did.Curious if the left hemispheres were indeed remaining awake to process information detected in the surrounding environment, Dr. Sasaki re-ran the experiment while presenting the sleeping participants with a mix of regularly timed beeps (蜂鸣声) of the same tone and irregular beeps of a different tone during the night. She worked out that, if the left hemisphere was staying alert to keep guard in a strange environment, then it would react to the irregular beeps by stirring people from sleep and would ignore the regularly timed ones. This is precisely what she found.46. What did researchers find puzzling about the first-night effect?A) To what extent it can trouble people. C) What circumstances may trigger it.B) What role it has played in evolution. D) In what way it can be beneficial.47. What do we learn about Dr. Yuka Sasaki doing her research?A) She found birds and dolphins remain alert while asleep.B) She found birds and dolphins sleep in much the same way.C) She got some idea from previous studies on birds and dolphinsD) She conducted studies on birds’ and dolphins’ sleeping patterns.48. What did Dr. Sasaki do when she first did her experiment?A) She monitored the brain activity of participants sleeping in a new environment.B) She recruited 35 participants from her Department of Psychological Sciences.C) She studied the differences between the two sides of participants’ brains.D) She tested her findings about birds and dolphins on human subjects.49. What did Dr. Sasaki do when re-running her experiment?A) She analyzed the negative effect of irregular tones on brains.B) She recorded participants’ adaptation to changed environment.C) She exposed her participants to two different stimuli.D) She compared the responses of different participants.50. What did Dr. Sasaki find about the participants in her experiment?A) They tended to enjoy certain tones more than others.B) They tended to perceive irregular beeps as a threat.C) They felt sleepy when exposed to regular beeps.D) They differed in their tolerance of irregular tones.Passage TwoQuestions 51 to 55 are based on the following passage.It’s time to reevaluate how women handle conflict at work. Being overworked or over-committed at home and on the job will not get you where you want to be in life. It will only slow you down and hinder your career goals.Did you know women are more likely than men to feel exhausted? Nearly twice as many women than men ages 18-44 reported feeling “very tired” or “exhausted”, according to a recent study.This may not be surprising given that this is the age range when women have children. It's also the age range when many women are trying to balance careers and home. One reason women may feel exhausted is that they have a hard time saying "no." Women want to be able todo it all volunteer for school parties or cook delicious meals-and so their answer to any request is often “Yes, I can.”Women struggle to say “no” in the workplace for similar reasons, including the desire to be liked by their colleagues. Unfortunately, this inability to say "no" may be hurting women's heath as well as their career.At the workplace, men use conflict as a way to position themselves, while women often avoid conflict or strive to be the peacemaker, because they don't want to be viewed as aggressive or disruptive at work. For example, there’s a problem that needs to be addressed immediately, resulting in a dispute over should be the oneto fix it. Men are more likely to face that dispute from the perspective of what benefits them most, whereas women may approach the same dispute from the perspective of what's the easiest and quickest way to resolve the problem-evenif that means doing the boring work themselves.This difference in handling conflict could be the deciding factor on who gets promoted to a leadership position and who does not. Leaders have to be able to delegate and manage resources wisely – including staff expertise. Shouldering more of the workload may not earn you that promotion. Instead, it may highlight your inability to delegate effectively.51. What does the author say is the problem with women?A) They are often unclear about the career goals to reach.B) They are usually more committed at home than on the job.C) They tend to be over-optimistic about how far they could go.D) They tend to push themselves beyond the limits of their ability.52. Why do working women of child-bearing age tend to feel drained of energy?A) They struggle to satisfy the demands of both work and home.B) They are too devoted to work and unable to relax as a result.C) They do their best to cooperate with their workmates.D) They are obliged to take up too many responsibilities.53. What may hinder the future prospects of career women?A) Their unwillingness to say “no”.B) Their desire to be considered powerful.C) An underestimate of their own ability.D) A lack of courage to face challenges.54.
