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. High School Sports Aren’t Killing AcademicsA)In this month’s Atlantic cover article, “The Case Against High-School Sports,” Amanda Ripley argues that school-sponsored sports programs should be seriously cut. She writes that, unlike most countries that outperform the United States on international assessments, American schools put too much of an emphasis on athletics, “ Sports are embedded in Americanschools in a way the y are not almost anywhere else,” she writes, “Yet this difference hardly ever comes up in domestic debates about America’s international mediocrity(平庸)in education.”B)American student-athletes reap many benefits from participating in sports, but the costs to the schools could outweigh their benefits, she argues, In particular, Ripley contends that sports crowd out the academic missions of schools: America should learn from South Korea and Finland and every other country at the top level of international test scores, all of whom emphasize athletics far less in school. ”Even in eighth grade, American kids spend more than twice the time Korean kids spend playing sports,” she writes, citing a 2010 study published in the Journal of Advanced Academics.C)It might well be true that sports are far more rooted in American high schools than in other countries. But our reading of international test scores finds no support for the argument against school athletics. Indeed, our own research and that of others lead us to make the opposite case. School-sponsored sports appear to provide benefits that seem to increase, not detract(减少)from, academic success.D)Ripley indulges a popular obsession(痴迷)with international test score comparisons, which show wide and frightening gaps between the United States and other countries. She ignores, however, the fact that states vary at least as much in test scores as do developed countries. A 2011 report from Harvard University shows that Massachusetts produces math scores comparable to South Korea and Finland, while Mississippi scores are closer to Trinidad and T obago. Ripley’s thesis about sports falls apart in light of this fact. Schools in Massachusetts provide sports programs while schools in Finland do not. Schoolsin Mississippi may love football while in Tobago interscholastic sports are nowhere near as prominent. Sports cannot explain these similarities in performance. They can’t explain international differences either.E)If it is true that sports undermine the academic mission of American schools, we would expect to see a negative relationship between the commitment to athletics and academic achievement. However, the University of Arkansas’s Daniel Bowen and Jay Greene actually find the opposite. They examine this relationship by a nalyzing schools’ sports winning percentages as well as student-athletic participation rates compared to graduation rates and standardized test score achievement over a five-year period for all public high schools in Ohio. Controlling for student poverty levels, demographics(人口统计状况), and district financial resources, both measures of a school’s commitment to athletics are significantly and positively related to lower dropout rates as well as higher test scores.F)On-the-field success and high participation in sports is not random-it requires focus and dedication to athletics. One might think this would lead schools obsessed with winning to deemphasize academics. Bowen and Greene’s results contradict that argument. A likely explanation for this seemingly counterintuitive(与直觉相反的)result is that success in sports programs actually facilitates or reflects greater social capital within a school’s community.G)Ripley cites the writings of renowned sociologist James Coleman, whose research in education was groundbreaking. Coleman in his early work held athletics in contempt, arguing that they crowded out schools’ academic missions. Ripley quotes his 1961 study, The Adolescent Society, where Colemanwrites, “Altogether, the trophy(奖品)case would suggest to the innocent visitor that he was entering an athletic club, not an educational institution.”H)However, in later research Coleman would show how the success of schools is highly dependent on what he termed social capital, “the social networks, and the relationships bet ween adults and children that are of value for the child’s growing up.”I)According to a 2013 evaluation conducted by the Crime Lab at the University of Chicago, a program called Becoming a Man-Sports Edition creates lasting improvements in the boys’ study habits and grade point averages. During the first year of the program, students were founds to be less likely to transfer schools or be engaged in violent crime. A year after the program, participants were less likely to have had an encounter with the juvenile justice system.J)If school-sponsored sports were completely eliminated tomorrow, many American students would still have opportunities to participate in organized athletics elsewhere, much like they do in countries such as Finland, Germany, and South Korea. The same is not certain when it comes to students from more disadvantaged backgrounds. In an overview of the research on non-school based after-school programs, researchers find that disadvantaged children participate in these programs at significantly lower rates. They find that low-income students have less access due to challenges with regard to transportation, non-nominal fees, and off-campus safety. Therefore, reducing or eliminating these opportunities would most likely deprive disadvantaged students of the benefits from athletic participation, not least of which is the opportunity to interact with positive role models outside of regular school hours.K)Another unfounded criticism that Ripley makes is bringing up the stereotype that athletic XX are typically lousy(蹩脚的)classroom teachers. “American principals, unlike the XX XX of principals around the world, make many hiring decisions with their sports teams in mind, which does not always end well for students,” she writes. Educators who seek em ployment at schools primarily for the purpose of coaching are likely to shirk(推卸)teaching responsibilities, the argument goes. Moreover, even in the cases where the employee is a teacher first and athletic coach second, the additional responsibilities that come with coaching likely comes at the expense of time otherwise spent on planning, grading, and communicating with parents and guardians.L)The data, however, do not seem to confirm this stereotype. In the most rigorous study on the classroom results of high school coaches, the University of Arkansas’s Anna Egalite finds that athletic coaches in Florida mostly tend to perform just as well as their non-coaching counterparts, with respect to raising student test scores. We do not doubt that teachers who also coach face serious tradeoffs that likely come at the expense of time they could dedicate to their academic obligations. However, as with sporting events, athletic coaches gain additional opportunities for communicating and serving as mentors(导师)that potentially help students succeed and make up for the costs of coaching commitments.M)If schools allow student-athletes to regularly miss out on instructional time for the sake of traveling to athletic competitions, that’s bad. However, such issues would be b etter addressed by changing school and state policies with regard to the scheduling of sporting events as opposed to total elimination.If the empirical evidence points to anything, it points towards school sponsored sports providing assets that are well worth the costs.N)Despite negative stereotypes about sports culture and Ripley’s presumption that academics and athletics are at odds with one another, we believe that the greater body of evidence shows that school-sponsored sports programs appear to benefit students. Successes on the playing field can carry over to the classroom and vice versa(反之亦然). More importantly, finding ways to increase school communities’ social capital is imperative to the success of the school as whole, not just the athletes.46.Stunets from low-income families have less access to off-campus sports programs.47.Amanda Ripley argues that America should learn from other countries that rank high in international tests and lay less emphasis on athletics.48.According to the author,Amanda Ripley fails to note that stunents'performance in exams varies from state to state.49.Amanda Ripley thinks that athletic coaches are poor at classroom instruction.50.James Coleman's later resrarch make an argument for a school's social capital.51.Reaearchers find that there is a ppsitive relationship between a school's commitment to athletics and academic achievements.52.Aa rigorous study finds that athletic coaches also do well in raising students'test scores.53.According to an evaluation,spograms contribute to students's academic preformance and character building.54.Amanda Ripley believes the emphasis on school sports shuold be brought up when trying to understand why Aamerican students are mediocre.55.James Coleman suggests in his earlier writings that school athletics would undermine a school's image.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 oneIt is easy to miss amid the day-to-day headlines of global economic recession, but there is a less conspicuous kind of social upheaval(剧变)underway that is fast altering both the face of the planet and the way human beings live. That change is the rapid acceleration of urbanization. In 2008, for the first time in human history, more than half the world’s population was livi ng in towns and cities. And as a recently published paper shows, the process of urbanization will only accelerate in the decades to come—with an enormous impact on biodiversity and potentially on climate change.As Karen Seto, the led author of the paper, points out, the wave of urbanization isn’t just about the migration of people into urban environments, but about the environments themselves becoming bigger to accommodate all those people. The rapid expansion of urban areas will have a huge impact on biodiversity hotspots and on carbon emissions in those urban areas.Humans are the ultimate invasive species—when the moveinto new territory, the often displace the wildlife that was already living there. And as land is cleared for those new cities—especially in the dense tropical forests—carbon will be released into the atmosphere as well. It’s true that as people in developing nations move from the countryside to the city, the shift may reduce the pressure on land, which could in turn be good for the environment. This is especially so in desperately poor countries, where residents in the countryside slash and burn forests each growing season to clear space for farming. But the real difference is that in developing nations, the move from rural areas to cities often leads to an accompanying increase in income — and that increase leads to an increase in the consumption of food and energy, which in turn causes a rise in carbon emissions. Getting enough to eat and enjoying the safety and comfort of living fully on the grid is certainly a good thing — but it does carry an environmental price.The urbanization wave can’t be stopped —and it shouldn’t be. But Seto’s paper does underscore the importance of managing that transition. If we do it the right way, we can redu ce urbanization’s impact on the environment. “There’s an enormous opportunity here, and a lot of pressure and responsibility to think about how we urbanize,” says Seto. “One thing that’s clear is that we can’t build cities the way we have over the last couple of hundred years. The scale of this transition won’t allow that.” We’re headed towards an urban planet no matter what, but whether it becomes heaven or hell is up to us.56. What issue does the author try to draw people’s attention to?A. The shrinking biodiversity worldwide.B. The rapid increase of world population.C. The ongoing global economic recession.D. The impact of accelerating urbanization.57. In what sense are humans the ultimate invasive species?A. They are much greedier than other species.B. They are a unique species born to conquer.C. They force other species out of their territories.D. They have an urge to expand their living space.下载文档。

What is the man think of doingPassage 1A report on sleep and nutrition released this month found that people who consistently went to bed earlier than 11 . took in fewer calories and ate more healthy food. In contrast, “night owls” who go to bed between 11 . and 3 . tend to consume more coffee, alcohol, refined sugars and processed meats than early risers. This report corresponds with the existing scientific literature on bedtime and wellness. The relationship between geeing more sleep and making better food choices is well-documented. A study published last year in The American Journal of Clinical Nutrition found that people who sleep more tend to eat less unhealthy food than their peers who don’t get much rest. And a 2015 study from the University of California, Berkeley, found that teens who go to bed late are more likely to gain weight over a five-year period. As a group, “night owls” types tend to eat less healthy food and take in more calories overall than early risers. The later one goes to bed, the more calories one records the next day. As yet a challenge to explain the cause-and-effect relationship between sleep and nutrition, there may be a third factor that impacts both of them. Or the relationship could be reversed, that is, people who eat less fall asleep earlier.Still, if late sleepers want to lose a few pounds, they can go to bed earlier than they usually do, thereby, reducing their chance of taking snacks before bedtime.do we learn about the report released this month10. What does the study from the University of California, Berkeley, find about teens who go to bed late11. Wha t should “night owls” do to reduce their consumption of unhealthy food Passage 2Researchers have found not just a diversity problem in Hollywood but actually an inclusion crisis. With less than a week before an Oscars ceremony that has already been criticized for an all-whit list of acting nominees, a study shows the film industry does worse than television. Just percent of film directors were female, and only 7 percent of films has cast whose balance of race and ethnicity reflected the country’s div ersity. When researches looked at all TV shows, they also found that women of color over 40 were regarded as “largely invisible” and just 22 percent of TV series creators were female. Overall, the study found half the films and TV shows had no Asian speaking characters and more than one-fifth of them had no black characters with dialogue. The film industry still functions as a straight, whit, boy’s club. When looking at how women are depicted, the study found female characters were four times more likely to be shown in sexy clothing and nearly four times as likely to be referred to as physically attractive. But their results also indicated films and TV shows withwomen or people of color in the important jobs behind the scenes—director, producer or writer—tended to have better diversity numbers. Across TV and film, the underrepresentation of non-white characters falls mostly on Hispanics. Among more than 10,000 characters, proportions of white, black and Asian characters came close to . population figures. But Hispanics were just percent of characters, despite being about 17 percent of the . population.12. Why has the Oscars ceremony been criticized13. What do we learn from the research14. Who are regarded as “largely invisible” on TV shows15. What does the speaker say about HispanicLecture 1When purchasing life insurance, there are many important factors to consider. One should buy the policies that give the most protection at the least cost, ensure the right family members, and consider the family’s financial needs. It is important to buy the insurance from companies that are financially sound and that are represented by honest, well-trained agents. At various stages in a person’s life, different kinds of life insurance are needed for particular situations. Jerry is single and has no dependents. Probable the only life insurance he needs is enough to cover his debts and burial expenses. Insurance can be purchased at a lower rate during the young years, but by buying while young, the premiums are paid in for a longer period of time. In the end, the amount paid for premium isabout the same. A person shouldn’t buy insurance protection that really isn’t necessary. Suppose that Jerry marries Jeannette, who is a college graduate and is working. Perhaps enough insurance would be needed to cover their debts and burial expenses. Now, Jeanette has quit work and their first child is on the way. They have purchased a home with a small down payment and a 30-year mortgage. The situation regarding life insurance takes on a different look. There are dependents who need financial protection. How much insurance is needed As the family increase in size, it is essential to add more insurance on the breadwinner to protect the dependents. When the children are young and depend upon the family for financial need, families with modest incomes have difficulty providing enough life insurance to protect the mother and the children. Families with modest incomes should insure the breadwinner or breadwinners first. When considering the amount of insurance for the mother with dependent children, substitute child care is a need that should be planned for until the children can care for themselves. The death of a small child would have no effect upon the income of the family. Perhaps a policy to meet funeral expenses would sufficient for the young child, although most people do not take out insurance on their young children. As the children become financially independent of the family, the emphasis on family financial security will shift from protection to saving for the retirement years. Every family situation is different, but it is important that each family give adequate thought to planning its financial future.16. What life insurance should a singe person buy, according to the speaker17. What should people do as their family increases in size18. When should one change their life insuranceLecture 2“Stereotype” may sound like a bad word, but there’s nothing bad about it. For one thing, stereotypes are often accurate. When you ask people about their concept of stereotypes, they get it pretty much right. Also, stereotypes are often positive, particularly of groups that we ourselves belong to. Some of the statistical generalizations may be positive as some groups have reputations for being smart, for being loyal, for being brave, for all sorts of things that are not at all negative. And so there’s nothing inherently wrong abut stereotypes.But there are problems with stereotypes. For one thing, they’re reliable insofar as they’re based on unbiased samples. But a lot of the information we get about human groups is through biased sources like how they’re represented in the media. And if these sources don’t give you an accurate depiction, your stereotype won’t be accurate.For e xample, many Jews have been troubled by Shakespeare’s depiction of Shylock. If the only Jew you know is Shakespeare’s Shylock, it’s going to be a very bad impression. So one problem with stereotypes is while we are good at drawing conclusions from them, of ten our information isn’t reliable.A second problem is that stereotypes, regardless of whether or not they’re accurate, can have a negative effect on the people that they apply to. And this is what psychologist, Claude Steele, described as stereotype threat. He has a vivid example of this. Here’s how to make African-Americans do worse on a math test. You have the test and you put on the test that they have to identify theirrace. The very act of acknowledging that they are African-Americans when given a test ignites in them thoughts of their own stereotype which is negative regarding academics and that makes them do worse. Want to know how to make a woman do worse on a math test Same thing, get her to write down her sex.One recent study found a sort of clever twist on this. When Asian-American women are given a test and they’re asked to mark down their race, they do better than they would otherwise do. They’re reminded of a positive stereotype that boosts their morale. You ask them, on the other hand, to mark down their sex, they do worse because they are reminded of a negative stereotype. That’s an example of how stereotypes have a potentially damaging effect on people.19. What does the speaker say about stereotype20. What lead to the bias of stereotype21. What does the speaker say is a problem with stereotypes22. What did one recent study find about stereotypeLecture 3Sometimes when you take a common drug, you may have a side effect. That is, the drug may cause some effect other than its intended one. When these side effects occur, they are called adverse reactions. Whenever you have an adverse reaction, you should stop taking the drug right away. Ask your pharmacist whether he can suggest a drug that will relieve the symptoms but that will not cause the adverse reaction. If an adverse reaction to a drug is serious, consult your doctor for advice at once.Drugs that are safe in the dosage stated on the label may be very dangerous in large dose. For example, aspirin is seldom thought of as dangerous, but there are many reports of accidental poisoning of young children who take too many aspirin pills as well as the possible development of Reye syndrome in children with flu. In adults, excessive used of some pain-killing drugs may cause serve kidney damage. Some drugs for relief of stomach upsets, when taken in excess, can perhaps cause serious digestive problems. You should never use any over-the-counter drug on a regular, continued basis, or in large quantities, except on your doctor’s advice. Y ou could be suffering from a serious illness that needs a doctor’s care.Each drug you take not only acts on the body but may also alter the effect of any other drug you are taking. Sometimes, this can cause dangerous or even fatal reactions. For example, aspirin increases the blood-thinning effects of drugs given to patients with heart disease. Therefore, a patient who has been taking such a drug may risk bleeding if her or she uses aspirin for a headache. Before using several drugs together you should ask your doctor and follow his advice. Your pharmacist can tell you whether certain drugs can safely be taken together.Alcohol may increase the effect of a drug—sleeping pills combine with alcohol to produce a sleepy feeling. When taking any drug, you should ask your doctor whether drinking alcohol could be dangerous in combination with the medicine.

If you show your respect for others, you are more likely to gain their respect. Just as the saying goes, “ Respect others, and you will be respected”. It indicates the great significance of respecting others in our daily life. First and foremost, respecting others gives them confidence and encouragement, especially those who are not as good as you. Your respect can help them become upbeat and active, and even enhance their self-assurance. In addition, polite words help improve your interpersonal relationships to a large extent. As mentioned above, if your respect proves to be effective, people will show their respect for you, too, and it will benefit your social intercourse. Last but not least, respecting others is a symbol of high quality, which shows one’s good upbringing.

You should write at least 150 words but no more than 200 words.正确答案：Be Generous with Your Help When it comes to the topic of help, we are frequently told that, “Help others, and you will be helped when you are in need. “ Simple as the saying is, it implies the importance of helping others in need. What I learn from the remark, in short words, is that helping others is helping yourself. Examples can easily be found to make this point clearer. The story of the ant and the dove is a case in point. An ant slipped into the river when drinking along the river. A dove heard his cries for help and threw him a leaf, which helped the ant float back to the bank. After a few days, a hunter was raising his gun to the dove as she was building her nest. Seeing this, the ant ran quickly to bite the hunter’s leg. The dove heard the hunter’s scream and flew away. All in all, this example indicates that when we offer our help to others, we are leaving a way open for the future. Helping others is a virtue, and we should take some measures to carry forward this virtue and do others a favor. Only in this way can we build a loving and harmonious society.解析：“帮助他人”是我们日常生活中非常熟悉的话题。

Snowden in 2013 that the government both cozied up to (讨好) certain tech companies and hacked into others to gain access to private data on an enormous scale, tech giants began to recognize the United States government as a hostile actor. But if the confrontation has crystallized in thislatest battle, it may already be heading toward a predictable conclusion: In the long run, the tech companies are destined to emerge victorious.[C] It may not seem that way at the moment. On the one side, you have the United States government's mighty legal and security apparatus fighting for data of the most sympathetic sort: the secrets buried in a dead mass murderer's phone. The action steins from a federal court order issued on Tuesday requiring Apple to help the Federal Bureau of Investigation (FBI) to unlock an iPhone used by one of the two attackers who killed 14 people in San Bernardino, California, in December.[D] In the other corner is the world's most valuable company, whose chief executive, Timothy Cook, has said he will appeal the court's order. Apple argues that it is fighting to preserve a principle that most of us who are addicted to our smartphones can defend: Weaken a single iPhone so that its contents can be viewed by the American government and you risk weakening all iPhones for any government intruder, anywhere.[E] There will probably be months of legal confrontation, and it is not at all clear which side will prevail in court, nor in the battle for public opinion and legislative favor. Yet underlying all of this is a simple dynamic: Apple, Google, Facebook and other companies hold most of the cards in this confrontation. They have our data, and their businesses depend on the global public's collective belief that they will do everything they can to protect that data. [F] Any crack in that front could be fatal for tech companies that must operate worldwide. If Apple is forced to open up an iPhone for an American law enforcement investigation, what is to prevent it from doing so for a request from the Russians or the Iranians? If Apple is forced to write code that lets the FBI get into the Phone 5c used by Syed Rizwan Farook, the male attacker in the San Bernardino attack, who would be responsible if some hacker got hold of that code and broke into its other devices?[G] Apple's stance on these issues emerged post-Snowden, when the company started putting in place a series of technologies that, by default, make use of encryption (加密）to limit access to people's data. More than that, Apple—and, in different ways, other tech companies, including Google, Facebook, Twitter and Microsoft—have made their opposition to the government's claims a point of corporate pride.[H] Apple's emerging global brand is privacy; it has staked its corporate reputation, not to mention the investment of considerable technical and financial resources, on limiting the sort of mass surveillance that was uncovered by Mr. Snowden. So now, for many cases involving governmental intrusions into data, once-lonely privacy advocates find themselves fighting alongside the most powerful company in the world.[I] "A comparison point is in the 1990s battles over encryption," said Kurt Opsahl, general counsel of the Electronic Frontier Foundation, a privacy watchdog group. "Then you had a few companies involved, but not one of the largest companies in the world coming out with a lengthy and impassioned post, like we saw yesterday from Timothy Cook. Its profile has really been raised."[J] Apple and oilier tech companies hold another ace: the technical means to keep making their devices more and more inaccessible. Note that Apple's public opposition to the government's request is itself a hindrance to mass government intrusion. And to get at the contents of a single iPhone, the government says it needs a court order and Apple's help to write new code; in earlier versions of the iPhone, ones that were created before Apple found religion on (热衷于) privacy, the FBI might have been able to break into the device by itself.[K] You can expect that noose (束缚) to continue to tighten. Experts said that whether or not Apple loses this specific case, measures that it could put into place in the future will almost certainly be able to further limit the government's reach.[L] That is not to say that the outcome of the San Bernardino case is insignificant. As apple and several security experts have argued, an order compelling Apple to write software that gives the FBI access to the iPhone in question would establish an unsettling precedent. The order essentially asks Apple to hack its own devices, and once it is in place, the precedent could be used to justify law enforcement efforts to get around encryption technologies in other investigations far removed from national security threats.[M] Once aimed with a method for gaining access to iPhones, the government could ask to use it proactively (先发制人地), before a suspected terrorist attack —leaving Apple in a bind as to whether to comply or risk an attack and suffer a public-relations nightmare. "This is a brand new move in the war against encryption," Mr. Opsahl said. "We have had plenty of debates in Congress and the media over whether the government should have a backdoor, and this is an end run (迂回战术) around that—here they come with an order to create that backdoor."[N] Yet it is worth noting that even if Apple ultimately loses this case, it has plenty of technical means to close a backdoor over time. "If they are anywhere near worth their salt as engineers, I bet they are rethinking their threat model as we speak," said Jonathan Zdziarski, a digital expert who studies the iPhone and its vulnerabilities.[O] One relatively simple fix, Mr. Zdziarski said, would be for Apple to mod ify future versions of the iPhone to require a user to enter a passcode before the phone will accept the sort of modified operating system that the FBI wants Apple to create. That way, Apple could not unilaterally introduce a code that weakens the iPhone—a user would have to consent to it.[P] "Nothing is 100 percent hacker-proof," Mr. Zdziarski said, but he pointed out that the judge's order in this case required Apple to provide "reasonable security assistance" to unlock Mr. Farook's phone. If Apple alters the security model of future iPhones so that even its own engineers' "reasonable assistance" will not be able to crack a given device when compelled by the government, a precedent set in this case might lose its lasting force. In other words, even if the FBI wins this case, in the long run, it loses.36. It is a popular belief that tech companies are committed to protecting their customers' private data.37. The US government believes that its access to people's iPhones could be used to prevent terrorist attacks.38. A federal court asked Apple to help the FBI access data in a terrorist's iPhone.39. Privacy advocates now have Apple fighting alongside them against government access to personal data.40. Snowden revealed that the American government had tried hard to access private data on a massive scale.41. The FBI might have been able to access private data in earlier iPhones without Apple's help.42. After the Snowden incident, Apple made clear its position to counter government intrusion into personal data by means of encryption.43. According to one digital expert, no iPhone can be entirely free from hacking.44. Timothy Cook's long web post has helped enhance Apple's image.45. Apple's CEO has decided to appeal the federal court's order to unlock a user's iPhone.Section C 仔细阅读Passage OneQuestions 46 to 50 are based on the following passage.At the base of a mountain in Tanzania's Gregory Rift, Lake Natron burns bright red, surrounded by the remains of animals that were unfortunate enough to fall into the salty water. Bats, swallows and more are chemically preserved in the pose in which they perished, sealed in the deposits of sodium carbonate in the water. The lake's landscape is bizarre and deadly—and made even more so by the fact that it's the place where nearly 75 percent of the world's flamingos (火烈鸟）are born.The water is so corrosive that it can burn the skin and eyes of unadapted animals. Flamingos, however, are the only species that actually makes life in the midst of all that death. Once every three or four years, when conditions are right, the lake is covered with the pink birds as they stop flight to breed. Three-quarters of the world's flamingos fly over from other salt lakes in the Rift Valley and nest on salt-crystal islands that appear when the water is at a specific level—too high and the birds can't build their nests, too low and predators can move briskly across the lake bed and attack. When the water hits the right level, the baby birds are kept safe from predators by a corrosive ditch."Flamingos have evolved very leathery skin on their legs so they can tolerate the salt water," says David Harper, a professor at the University of Leicester. "Humans cannot, and would die if their legs were exposed for any length of time." So far this year, water levels have been too high for the flamingos to nest.Some fish, too, have had limited success vacationing at the lake as less salty lagoons (泻湖) form on the outer edges from hot springs flowing into Lake Natron. Three species of tilapia (罗非鱼) thrive there part-time. "Fish have a refuge in the streams and can expand into the lagoons when the lake is low and the lagoons are separate," Harper said. "All the lagoons join when the lake is high and fish must retreat to their stream refuges or die." Otherwise, no fish are able to survive in the naturally toxic lake.This unique ecosystem may soon be under pressure. The Tanzanian government has once again started mining the lake for soda ash, used for making chemicals, glass and detergents. Although the planned operation will be located more than 40 miles away, drawing the soda ash in through pipelines, conservationists worry it could still upset the natural water cycle and breeding grounds. For now, though, life prevails—even in a lake that kills almost everything it touches.46. What can we learn about Lake Natron?A) It is simply uninhabitable for most animals.B) It remains little known to the outside world.C) It is a breeding ground for a variety of birds.D) It makes an ideal habitat for lots of predators.47. Flamingos nest only when the lake water is at a specific level so that their babies can .A) find safe shelter more easilyB) grow thick feathers on their feetC) stay away from predatorsD) get accustomed to the salty water48. Flamingos in the Rift Valley are unique in that .A) they can move swiftly across lagoonsB) they can survive well in salty waterC) they breed naturally in corrosive ditchesD) they know where and when to nest49. Why can certain species of tilapia sometimes survive around Lake Natron?A) They can take refuge in the less salty waters.B) They can flee quick enough from predators.C) They can move freely from lagoon to lagoon.D) They can stand the heat of the spring water.50. What may be the consequence of Tanzanian government's planned operation?A) The accelerated extinction of flamingos.B) The change of flamingos' migration route.C) The overmining of Lake Natron's soda ash.D) The disruption of Lake Natron's ecosystem.Passage TwoQuestions 51 to 55 are based on the following passage.It is the season for some frantic last-minute math—across the country, employees of all stripes are counting backward in an attempt to figure out just how much paid time-off they have left in their reserves. More of them, though, will skip those calculations altogether and just power through the holidays into 2017: More than half of American workers don't use up all of their allotted vacation days each year.Not so long ago, people would have turned up their noses at that kind of dedication to the job. As marketing professors Silvia Bellezza, Neeru Paharia, and Anat Keinan recently explained in Harvard Business Review (HBR), leisure time was once seen as an indicator of high social status, something attainable only for those at the top. Since the middle of the 20th century, though, things have turned the opposite way—these days, punishing hours at your desk, rather than days off, are seen as the mark of someone important.In a series of several experiments, the researchers illustrated just how much we've come to admire busyness, or at least the appearance of it. Volunteers read two passages, one about a man who led a life of leisure and another about a man who was over-worked and over-scheduled; when asked to determine which of the two had a higher social status, the majority of the participants said the latter. The same held true for people who used products that implied they were short on time: In one experiment, for example, customers of the grocery-delivery service Peapod were seen as of higher status than people who shopped at grocery stores that were equally expensive; in another, people wearing wireless headphones were considered further up on the social ladder than those wearing regular headphones, even when both were just used to listen to music.In part, the authors wrote in HBR, this pattern may have to do with the way work itself has changed over the past several decades.We think that the shift from leisure-as-status to busyness-as-status may be linked to the development of knowledge-intensive economics. In such economies, individuals who possess the human capital characteristics that employers or clients value (e. g. , competence and ambition) are expected to be in high demand and short supply on the job market. Thus, by telling others that we are busy and working all the time, we are implicitly suggesting that we are sought after, which enhances our perceived status.Even if you feel tempted to sacrifice your own vacation days for fake busyness, though, at least consider leaving your weekends unscheduled. It's for your own good.51. What do most employees plan to do towards the end of the year?A) Go for a vacation.B) Keep on working.C) Set an objective for next year.D) Review the year's achievements.52. How would people view dedication to work in the past?A) They would regard it as a matter of course.B) They would consider it a must for success.C) They would look upon it with contempt.D) They would deem it a trick of businessmen.53. What did the researchers find through a series of experiments?A) The busier one appears, the more respect one earns.B) The more one works, the more one feels exploited.C) The more knowledge one has, the more competent one will be.D) The higher one's status, the more vacation time one will enjoy.54. What may account for the change of people's attitude towards being busy?A) The fast pace of life in modern society.B) The fierce competition in the job market.C) The widespread use of computer technology.D) The role of knowledge in modern economy.55. What does the author advise us to do at the end of the passage?A) Schedule our time properly for efficiency.B) Plan our weekends in a meaningful way.C) Find time to relax however busy we are.D) Avoid appearing busy when we are not.Part I Translation (30minutes)Directions：For this part, you are allowed 30 minutes to translate a passage from Chinese into English. You should write your answer on Answer Sheet 2.洞庭湖位于湖南省东北部，面积很大，但湖水很浅。
2017年12月英语六级之阅读理解(三套)
2017年12月英语六级之阅读理解Passage OneQuestions 46 to 50 are based on the following passage.You may have heard that Coca-Cola once contained an ingredient capable of sparking particular devotion in consumers: cocaine. The "coca" in the name referred to the extracts of coca leaf that the drink's originator, chemist John Pemberton, mixed with his sugary syrup (浆汁). At the time, coca leaf extract mixed with wine was a common tonic (滋补品), and Pemberton's sweet brew was a way to get around local laws prohibiting the sale of alcohol. But the other half of the name represents another ingredient, less infamous (名声不好的), perhaps, but also strangely potent: the kola nut.In West Africa, people have long chewed kola nuts as stimulants, because they contain caffeine that also occurs naturally in tea, coffee, and chocolate. They also have heart stimulants.Historian Paul Lovejoy relates that the cultivation of kola nuts in West Africa is hundreds of years old. The leafy, spreading trees were planted on graves and as part of traditional rituals. Even though the nuts, which need to stay moist, can be somewhat delicate to transport, traders carried them hundreds of miles throughout the forests and grasslands.Europeans did not know of them until the 1500s, when Portuguese ships arrived on the coast of what is now Sierra Leone. And while the Portuguese took part in the trade, ferrying nuts down the coast along with other goods, by 1620, when English explorer Richard Jobson made his way up the Gambia, the nuts were still peculiar to his eyes.By the late 19th century, kola nuts were being shipped by the tonne to Europe and the US. Many made their way into medicines, intended as a kind of energy boost. One such popular medicinal drink was Vin Mariani, a French product consisting of coca extract mixed with red wine It was created by a French chemist, Angelo Mariani, in 1863. So when Pemberton created his drink, it represented an ongoing trend. When cocaine eventually fell from grace as a beverage ingredient, kola-extract colas became popular.The first year it was available, Coca-Cola averaged nine servings a day across all the Atlanta soda fountains where it was sold. As it grew more popular, the company sold rights to bottle the soda, so it could travel easily. Today about 1.9 billion Cokes purchased daily. It’s become so iconic that attempts to change its taste in 1985-sweetening it in a move projected to boost sales proved disastrous, with widespread anger from consumers. ”Coca-Cola Classic” returned to store shelves just th ree months afte r the ”New Coke” was released.These days, the Coca-Cola recipe is a closely guarded secret. But it’s said to no longer contain kola nut extract, relying instead on artificial imitations to achieve the flavor.46.【题干】What do we learn about chemist John Pemberton?A. He used a strangely potent ingredient in a food supplement.B .He created a drink containing alcohol without breaking law.C .He became notorious because of the coca drink he developed.D .He risked breaking local law to make a drink with coca leaves.47.【题干】What does the passage say about kola nuts?A.Their commercial value was first discovered by Portuguese settlers.B.They contain some kind of energy boost no found in any other food.C.Many were shipped to Europe in the late 19th century for medicinal use.D.They were strange to the Europeans when first imported from West Africa.48.【题干】How come kola-extract colas became popular?A.Cocaine had become notorious.B.Alcoholic drinks were prohibited.C.Fountains were set up to sell them.D.Rights were sold to bottle the soda.49.【题干】What is known about the taste of Coca-Cola?A.I was so designed as to create addition in consumers.B.It still relies on traditional kola nut extract.C.It has become more popular among the old.D.I has remained virtually unchanged since its creation.50.【题干】What is the passage mainly about?A.The evolution of Coca-Cola.C.The medicinal value of Coca-Cola.B.The success of Coca-Cola.D.The business strategy of Coca-Cola.Passage TwoQuestions 51 to 55 are based on the following passage.Twenty years ago the Urban Land Institute defined the two types of cities that dominated the US landscape: smaller cities that operated around standard 9-5 business hours and large metropolitan areas that ran all 24 hours of the day. Analyzing and comparing cities using the lens of this basic divide gives interesting context to how investment capital flows and housing prices have shifted.In recent years, many mid-sized cities have begun to a middle-of-the-road approach incorporating the excitement and opportunity of large cities with small cities' quiet after midnight. These 18-hour cities are beginning to make waves in real estate rankings and attract more real estate investment. What is underlying this new movement in real estate, and why do these cities have so much appeal?18-hour cities combine the best of 24-hour and 9-5 cities, which contribute to downtown revitalization. For decades, many downtown cores in Small to mid-sized cities were abandoned after work hours by worker who lived in the suburbs. Movement out of city centers was widespread, and downtown tenants were predominantly made up of the working poor. This generated little commerce for downtown business in the evenings, which made business and generating tax revenue for municipal upkeep difficult. With the rise of a new concept in urban areas that caused the real estate pushes, in major cities like San Francisco or New York, has inspired a type of forward thinking urbanity and policy in smaller cities.Transforming downtown areas so that they incorporate modern housing and improved walkability to local restaurants, retail, and entertainment - especially when combined with improved infrastructure for cyclists and public transit - makes them appeal to a more affluent demographic, These adjustments encourage employers in the knowledge and talent industries to keep their offices downtown. Access to foot traffic and proximity to transit allow the type of entertainment-oriented businesses such as bars and restaurants to stay open later, which attracts both younger, creative workers and baby boomers nearing retirement alike. Because of their smaller size, most keep hours that allow people to enjoy themselves, then have some quiet after midnight, as opposed to large major cities like New York, where the buzz of activity is ongoing.These 18-hour cities are rapidly on the rise and offer great opportunities for homeowner investment. In many of these cities such as Denver, a diverse and vigorous economy attracted to the urban core has offered stable employment for residents. The right urban mix has propped up home occupancy, increased property values and attracted significant investment capital.51.【题干】What do we learn about American cities twenty years ago?A.They were divided into residential and business areas.B.Their housing prices were linked with their prosperity.C.There was a clear divide between large and small cities.D.They were places where large investment capital flowed.52.【题干】What can be inferred from the passage about 18-hour cities?A.They especially appeal to small businesses.B.They have seen a rise in property prices.C.They have replaced quiet with excitement.D.They have changed America's landscape.53.【题干】Years ago, many downtown cores in small to mid-sized cities_____.A.had hardly any business activity.C.exhibited no signs of prosperity.B.were crowded in business hours.D.looked deserted in the evenings54.【题干】What characterizes the new downtown areas in 18-hour cities?A.A sudden emergence of the knowledge industry.B.Flooding in of large crowds of migrant workers.C.Modernized housing and improved infrastructure.D.More comfortable life and greater upward mobility.55.【题干】What have 18-hour cities brought to the local residents?A.More chances for promotion.C.Greater cultural diversity.B.Healthier living environment.D.Better job opportunities.（第二套）Passage One Questions 46 to 50 are based or the following passage.In the beginning of the movie I. Robot, a robot has to decide whom to save after two cars plunge into the water——Del Spooner or a child. Even though Spooner screams "Save her! Save her!" the robot rescues him because it calculates that he has a 45 percent chance of survival compared to Sarah's 11 percent. The robot's decision and its calculated approach raise an important question: would humans make the same choice? And which choice would we want our robotic counterparts to make?Lsaac Asimov evaded the whole notion of morality in devising his three laws of robotics, which hold that I.Robots cannot harm humans or allow humans to come to harm; 2. Robots must obey preservation, unless doing so conflict with law 1; and 3. Robots must act in self-preservation, unless doing so conflicts with laws l or 2. These laws are programmed into Asimov's robots——they don't have to think, judge, or value. They don't have to like humans or believe that hurting them is wrong or bad. They simply don't do it.The robot who rescues Spooner's life in I.Robot follows Asimov's zeroth law: robots cannot harm humanity (as opposed to individual humans) or allow humanity to come to harm一an expansion of the first law that allows robots to determine what's in the greater good. Under the first law, a robot could not harm dangerous gunman, but under the zeroth law, a robot could kill the gunman to save others.Whether it's possible to program a robot with safeguards such as Asimov's laws ins debatable. A word such as "harm" is vague (what about emotional harm? Is replacing a human employee harm?), and abstract concepts present coding problems. The robots in As imov‘s fiction expose complications and loopholes in the three laws, and even when the laws work, robots still have to assess situations.Assessing situations can be complicated. A robot has to identify the players, conditions, abd possible outcomes for various scenarios. It's doubtful that a computer program can do that—at least, not without some undesirable results. A roboticist at the Bristol Robotics Laboratory programmed a robot to save human proxies(替身)called "H-bots" from danger. When two H-bots heads for danger, the robot successfully pushed it out of the way. But when two H-bots became imperiled, the robot choked 42 percent of the time, unable to decide which to save and letting them both "die." The experiment highlights importance of morality: without it, how can a robot decide whom to save or what's best for humanity, especially if it can't calculate survival odds?46.【题干】What question does the example in the movie raise?A.Whether robots can reach better decisions.B.Whether robots follow Asimov's zero law.C.How robots may make bad judgments.D.How robots should be programmed.47.【题干】What does the author think of Asimov's three laws of robotics?A.They are apparently divorced from reality.B.They did not follow the coding system of robotics.C.They laid a solid foundation for robotics.D.They did not take moral issues into consideration.48.【题干】what does the author say about Asimov's robots?A.They know what is good or bad for human beings.B.They are programmed not to hurt human beings.C.They perform duties in their owners' best interest.D.They stop working when a moral issue is involved.49.【题干】What does the author want to say by mentioning the word "harm" in Asimov s laws?A.Abstract concepts are hart to program.B.It is hard for robots to make decisions.C.Robots may do harm in certain situations.D.Asimov's laws use too many vague terms.50.【题干】What has the roboticist at the Bristol Robotics Laboratory found in his experiment?A.Robots can be made as intelligent as human beings some day.B.Robots can have moral issues encoded into their programs.C.Robots can have trouble making decisions in complex scenarios.D.Robots can be programmed to perceive potential perils.Passage TwoOur world now moves so fast that we seldom stop to see just how far we have come in just a few years. The latest iPhone6s, for example, has a dual-core processor and fits nicely into your pocket. By comparison, you would expect to find a technological specification like this on your standard laptop in an office anywhere in the world.It's no wonder that new applications for the Internet of Things are moving ahead fast when almost every new device we buy has a plug on the end of it or a wireless connection to the internet. Soon, our current smartphone lifestyle will expand to create our own smart home lifestyle too.All researchers agree that close to 25 billion devices, things and sensors will be connected by 2020 which incidentally is also the moment that Millennials (千禧一代)are expected to make up 75 percent of our overallworkforce, and the fully connected home will become a reality for large numbers of people worldwide.However, this is just the tip of the proverbial iceberg as smart buildings and ever cities increasingly become the norm as leaders and business owners begin to wake up to the massive savings that technology can deliver through connected sensors and new forms of automation coupled with intelligent energy and facilities management.Online security cameras, intelligent lighting and a wealth of sensors that control both temperature and air quality are offering an unprecedented level of control, efficiency, and improvements to what were once classed necessary costs when running a business or managing a large building.We can expect that the ever-growing list of devices, systems and environments remain connected, always online and talking to each other. The big benefit will not only be in the housing of this enormous and rapidly growing amount of data, but will also be in the ability to run real time data analytics to extract actionable and ongoing knowledge.The biggest and most exciting challenge of this technology is how to creatively leverage this ever-growing amount of data to deliver cost savings, improvements and tangible benefits to both businesses and citizens of these smart cities.The good news is that most of this technology is already invented. Let's face it, it wasn't too long ago that the idea of working from anywhere and at anytime was some form of a distant utopian(乌托邦式的)dream, and yet now we can perform almost any office-based task from any location in the world as long as we have access to the internet.It's time to wake up to the fact that making smart buildings, cities and homes will dramatically improve our quality of life in the years ahead.51.【题干】What does the example of iPhone 6s serve to show?A.The huge capacity of the smartphones people now use.B.The widespread use of smartphones all over the world.C.The huge impact of new technology on people's everyday life.D.The rapid technological progress in a very short period of time.52.【题干】What can we expect to see by the year 2020?A.Apps for the Internet of Things.B.The popularization of smart homes.C.The emergence of Millennials.D.Total globalization of the world.53.【题干】What will business owners do when they become aware of the benefits of the Internet of Things?A.Employ fewer workers in their operations.B.Gain automatic control of their businesses.C.Invest in more smart buildings and cities.D.Embrace whatever new technology there is.54【题干】What is the most exciting challenge when we possess more and more data?A.How to turn it to profitable use.B.How to do real time data analysis.C.How to link the actionable systems.D.How to devise new ways to store it.55【题干】What does the author think about working from any where and at any time?A.It is feasible with a connection to the internet.B.It will thrive in smart buildings, cities and homes.C.It is still a distant utopian dream for ordinary workers.D.It will deliver tangible benefits to both boss and worker.（第三套）Passage One46-50 ACBAD46.
