In a rare unanimous ruling, the US Supreme Court has overturned the corruption conviction of a former Virginia governor, Robert McDonnell. But it did so while holding its nose at the ethics of his conduct, which included accepting gifts such as a Rolex watch and a Ferrari automobile from a company seeking access to government.The high court's decision said the judge in Mr. McDonnell's trial failed to tell a jury that it must look only at his “official acts,” or the former governor's decisions on “specific” and “unsettled” issues related to his duties.Merely helping a gift-giver gain access to other officials, unless done with clear intent to pressure those officials, is not corruption, the justices found.The court did suggest that accepting favors in return for opening doors is “distasteful” and “nasty”. But under anti-bribery laws, proof must be made of concrete benefits, such as approval of a contract or regulation. Simply arranging a meeting, making a phone call, or hosting an event is not an “official act.’’The court's ruling is legally sound in defining a kind of favoritism that is not criminal. Elected leaders must be allowed to help supporters deal with bureaucratic problems without fear of prosecution for bribery. “The basic compact underlying representative government, ” wrote Chief Justice John Roberts for the court, “assumes that public officials will hear from their constituents and act on their concerns.”But the ruling reinforces the need for citizens and their elected representatives, not the courts, to ensure equality of access to government. Officials must not be allowed to play favorites in providing information or in arranging meetings simply because an individual or group provides a campaign donation or a personal gift. This type of integrity requires well-enforced laws in government transparency, such as records of official meetings, rules on lobbying, and information about each elected leader's source of wealth.Favoritism in official access can fan public perceptions of corruption. But it is not always corruption. Rather officials must avoid double standards, or different types of access for average people and the wealthy. If connections can be bought, a basic premise of democratic society— that all are equal in treatment by government — is undermined. Good governance rests on an understanding of the inherent worth of each individual.The court's ruling is a step forward in the struggle against both corruption and official favoritism. 1.The underlined sentence (Paragraph 1) most probably shows that the court(  ).2.According to Paragraph 4, an official act is deemed corruptive only if it involves (  ).  3.The court's ruling is based on the assumption that public officials are (  ).  4.Well-enforced laws in government transparency are needed to (  ).  5.The author's attitude toward the court's ruling is(  ).

“There is one and only one social responsibility of business,” wrote Milton Friedman, a Nobel prize-winning economist,“ That is, to use its resources and engage in activities designed to increase its profits.’’ But even if you accept Friedman's premise and regard corporate social responsibility (CSR) policies as a waste of shareholders' money, things may not be absolutely clear-cut. New research suggests that CSR may create monetary value for companies—at least when they are prosecuted for corruption.The largest firms in America and Britain together spend more than $15 billion a year on CSR, according to an estimate by EPG, a consulting firm. This could add value to their businesses in three ways. First, consumers may take CSR spending as a “signal” that a company's products are of high quality. Second, customers may be willing to buy a company's products as an indirect way to donate to the good causes it helps. And third, through a more diffuse “halo effect,” whereby its good deeds earn it greater consideration from consumers and others.Previous studies on CSR have had trouble differentiating these effects because consumers can be affected by all three. A recent study attempts to separate them by looking at bribery prosecutions under America's Foreign Corrupt Practices Act (FCPA). It argues that since prosecutors do not consume a company's products as part of their investigations, they could be influenced only by the halo effect.The study found that, among prosecuted firms, those with the most comprehensive CSR programmes tended to get more lenient penalties. Their analysis ruled out the possibility that it was firms' political influence, rather than their CSR stand, that accounted for the leniency: Companies that contributed more to political campaigns did not receive lower fines.In all, the study concludes that whereas prosecutors should only evaluate a case based on its merits, they do seem to be influenced by a company's record in CSR. “We estimate that either eliminating a substantial lab our-rights concern, such as child labour, or increasing corporate giving by about 20% results in fines that generally are 40% lower than the typical punishment for bribing foreign officials,” says one researcher.Researchers admit that their study does not answer the question of how much businesses ought to spend on CSR. Nor does it reveal how much companies are banking on the halo effect, rather than the other possible benefits, when they decide their do-gooding policies. But at least they have demonstrated that when companies get into trouble with the law, evidence of good character can win them a less costly punishment.1.The author views Milton Friedman's statement about CSR with(  ).2.According to Paragraph 2, CSR helps a company by (  ).  3.The expression “more lenient”(Paragraph 4) is closest in meaning to (  ).  4.When prosecutors evaluate a case, a company's CSR record (  ).  5.Which of the following is true of CSR, according to the last paragraph?

The decision of the New York Philharmonic to hire Alan Gilbert as its next music director has been the talk of the classical-music world ever since the sudden announcement of his appointment in 2009. For the most part, the response has been favorable, to say the least. “Hooray! At last!” wrote Anthony Tommasini, a sober-sided classical-music critic.One of the reasons why the appointment came as such a surprise, however, is that Gilbert is comparatively little known. Even Tommasini, who had advocated Gilbert’s appointment in the Times, calls him “an unpretentious musician with no air of the formidable conductor about him.” As a description of the next music director of an orchestra that has hitherto been led by musicians like Gustav Mahler and Pierre Boulez, that seems likely to have struck at least some Times readers as faint praise.For my part, I have no idea whether Gilbert is a great conductor or even a good one. To be sure, he performs an impressive variety of interesting compositions, but it is not necessary for me to visit Avery Fisher Hall, or anywhere else, to hear interesting orchestral music. All I have to do is to go to my CD shelf, or boot up my computer and download still more recorded music from iTunes.Devoted concertgoers who reply that recordings are no substitute for live performance are missing the point. For the time, attention, and money of the art-loving public, classical instrumentalists must compete not only with opera houses, dance troupes, theater companies, and museums, but also with the recorded performances of the great classical musicians of the 20th century. These recordings are cheap, available everywhere, and very often much higher in artistic quality than today’s live performances; moreover, they can be “consumed” at a time and place of the listener’s choosing. The widespread availability of such recordings has thus brought about a crisis in the institution of the traditional classical concert.One possible response is for classical performers to program attractive new music that is not yet available on record. Gilbert’s own interest in new music has been widely noted: Alex Ross, a classical-music critic, has described him as a man who is capable of turning the Philharmonic into “a markedly different, more vibrant organization.” But what will be the nature of that difference? Merely expanding the orchestra’s repertoire will not be enough. If Gilbert and the Philharmonic are to succeed, they must first change the relationship between America’s oldest orchestra and the new audience it hopes to attract.1. We learn from Paragraph 1 that Gilbert’s appointment has ________.2. Tommasini regards Gilbert as an artist who is ________.3. The author believes that the devoted concertgoers ________.4. According to the text, which of the following is true of recordings?5. Regarding Gilbert’s role in revitalizing the Philharmonic, the author feels ________.

When Liam McGee departed as president of Bank of America in August, his explanation was surprisingly straight up. Rather than cloaking his exit in the usual vague excuses, he came right out and said he was leaving “to pursue my goal of running a company.” Broadcasting his ambition was “very much my decision,” McGee says. Within two weeks, he was talking for the first time with the board of Hartford Financial Services Group, which named him CEO and chairman on September 29.McGee says leaving without a position lined up gave him time to reflect on what kind of company he wanted to run. It also sent a clear message to the outside world about his aspirations. And McGee isn’t alone. In recent weeks the No. 2 executives at Avon and American Express quit with the explanation that they were looking for a CEO post. As boards scrutinize succession plans in response to shareholder pressure, executives who don’t get the nod also may wish to move on. A turbulent business environment also has senior managers cautious of letting vague pronouncements cloud their reputations.As the first signs of recovery begin to take hold, deputy chiefs may be more willing to make the jump without a net. In the third quarter, CEO turnover was down 23% from a year ago as nervous boards stuck with the leaders they had, according to Liberum Research. As the economy picks up, opportunities will abound for aspiring leaders.The decision to quit a senior position to look for a better one is unconventional. For years executives and headhunters have adhered to the rule that the most attractive CEO candidates are the ones who must be poached. Says Korn/Ferry senior partner Dennis Carey: “I can’t think of a single search I’ve done where a board has not instructed me to look at sitting CEOs first.”Those who jumped without a job haven’t always landed in top positions quickly. Ellen Marram quit as chief of Tropicana a decade ago, saying she wanted to be a CEO. It was a year before she became head of a tiny Internet-based commodities exchange. Robert Willumstad left Citigroup in 2005 with ambitions to be a CEO. He finally took that post at a major financial institution three years later.Many recruiters say the old disgrace is fading for top performers. The financial crisis has made it more acceptable to be between jobs or to leave a bad one. “The traditional rule was it’s safer to stay where you are, but that’s been fundamentally inverted,” says one headhunter. “The people who’ve been hurt the worst are those who’ve stayed too long.”1. When McGee announced his departure, his manner can best be described as being ________.2. According to Paragraph 2, senior executives’ quitting may be spurred by ________.3. The word “poached” (Paragraph 4) most probably means ________.4. It can be inferred from the last paragraph that ________.5. Which of the following is the best title for the text?

Of all the changes that have taken place in English-language newspapers during the past quarter-century, perhaps the most far-reaching has been the inexorable decline in the scope and seriousness of their arts coverage. It is difficult to the point of impossibility for the average reader under the age of forty to imagine a time when high-quality arts criticism could be found in most big-city newspapers. Yet a considerable number of the most significant collections of criticism published in the 20th century consisted in large part of newspaper reviews. To read such books today is to marvel at the fact that their learned contents were once deemed suitable for publication in general-circulation dailies.We are even farther removed from the unfocused newspaper reviews published in England between the turn of the 20th century and the eve of World War II, at a time when newsprint was dirt-cheap and stylish arts criticism was considered an ornament to the publications in which it appeared. In those far-off days, it was taken for granted that the critics of major papers would write in detail and at length about the events they covered. Theirs was a serious business, and even those reviewers who wore their learning lightly, like George Bernard Shaw and Ernest Newman, could be trusted to know what they were about. These men believed in journalism as a calling, and were proud to be published in the daily press. “So few authors have brains enough or literary gift enough to keep their own end up in journalism,” Newman wrote, “that I am tempted to define ‘journalism’ as ‘a term of contempt applied by writers who are not read to writers who are’.”Unfortunately, these critics are virtually forgotten. Neville Cardus, who wrote for the Manchester Guardian from 1917 until shortly before his death in 1975, is now known solely as a writer of essays on the game of cricket. During his lifetime, though, he was also one of England's foremost classical-music critics, a stylist so widely admired that his Autobiography (1947) became a best-seller. He was knighted in 1967, the first music critic to be so honored. Yet only one of his books is now in print, and his vast body of writings on music is unknown save to specialists.Is there any chance that Cardus's criticism will enjoy a revival? The prospect seems remote. Journalistic tastes had changed long before his death, and postmodern readers have little use for the richly upholstered Vicwardian prose in which he specialized. Moreover, the amateur tradition in music criticism has been in headlong retreat.1.It is indicated in Paragraphs 1 and 2 that(  ).2.Newspaper reviews in England before World War II were characterized by (  ).  3.Which of the following would Shaw and Newman most probably agree on?4.What can be learned about Cardus according to the last two paragraphs?5.What would be the best title for the text?

In his book The Tipping Point, Malcolm Gladwell argues that “social epidemics” are driven in large part by the actions of a tiny minority of special individuals, often called influentials, who are unusually informed, persuasive, or well connected. The idea is intuitively compelling, but it doesn't explain how ideas actually spread.The supposed importance of influentials derives from a plausible-sounding but largely untested theory called the “two-step flow of communication”: Information flows from the media to the influentials and from them to everyone else. Marketers have embraced the two-step flow because it suggests that if they can just find and influence the influentials, those selected people will do most of the work for them. The theory also seems to explain the sudden and unexpected popularity of certain looks, brands, or neighborhoods. In many such cases, a cursory search for causes finds that some small group of people was wearing, promoting, or developing whatever it is before anyone else paid attention. Anecdotal evidence of this kind fits nicely with the idea that only certain special people can drive trends. In their recent work, however, some researchers have come up with the finding that influentials have far less impact on social epidemics than is generally supposed. In fact, they don't seem to be required at all.The researchers' argument stems from a simple observation about social influence: with the exception of a few celebrities like Oprah Winfrey—whose outsize presence is primarily a function of media, not interpersonal, influence—even the most influential members of a population simply don't interact with that many others. Yet it is precisely these non-celebrity influentials who, according to the two-step-flow theory, are supposed to drive social epidemics, by influencing their friends and colleagues directly. For a social epidemic to occur, however, each person so affected, must then influence his or her own acquaintances, who must in turn influence theirs, and so on; and just how many others pay attention to each of these people has little to do with the initial influential. If people in the network just two degrees removed from the initial influential prove resistant, for example, the cascade of change won't propagate very far or affect many people.Building on the basic truth about interpersonal influence, the researchers studied the dynamics of social influence by conducting thousands of computer simulations of populations, manipulating a number of variables relating to people's ability to influence others and their tendency to be influenced. They found that the principal requirement for what is called “global cascades” — the widespread propagation of influence through networks—is the presence not of a few influentials but, rather, of a critical mass of easily influenced people. 1.By citing the book The Tipping Point, the author intends to(  ).2.The author suggests that the "two-step-flow theory" (  ).  3.What the researchers have observed recently shows that (  ).  4.The underlined phrase “these people” in paragraph 4 refers to the ones who (  ).  5.What is the essential element in the dynamics of social influence?

Bankers have been blaming themselves for their troubles in public. Behind the scenes, they have been taking aim at someone else: the accounting standard-setters. Their rules, moan the banks, have forced them to report enormous losses, and it's just not fair. These rules say they must value some assets at the price a third party would pay, not the price managers and regulators would like them to fetch.Unfortunately, banks' lobbying now seems to be working. The details may be unknowable, but the independence of standard-setters, essential to the proper functioning of capital markets, is being compromised. And, unless banks carry toxic assets at prices that attract buyers, reviving the banking system will be difficult.After a bruising encounter with Congress, America's Financial Accounting Standards Board (FASB) rushed through rule changes. These gave banks more freedom to use models to value illiquid assets and more flexibility in recognizing losses on long-term assets in their income statements. Bob Herz, the FASB's chairman, cried out against those who “question our motives.” Yet bank shares rose and the changes enhance what one lobbying group politely calls “the use of judgment by management.”European ministers instantly demanded that the International Accounting Standards Board (IASB) do likewise. The IASB says it does not want to act without overall planning, but the pressure to fold when it completes its reconstruction of rules later this year is strong. Charlie McCreevy, a European commissioner, warned the IASB that it did “not live in a political vacuum” but “in the real world” and that Europe could yet develop different rules.It was banks that were on the wrong planet, with accounts that vastly overvalued assets. Today they argue that market prices overstate losses, because they largely reflect the temporary illiquidity of markets, not the likely extent of bad debts. The truth will not be known for years. But banks' shares trade below their book value, suggesting that investors are skeptical. And dead markets partly reflect the paralysis of banks which will not sell assets for fear of booking losses, yet are reluctant to buy all those supposed bargains.To get the system working again, losses must be recognized and dealt with. America's new plan to buy up toxic assets will not work unless banks mark assets to levels which buyers find attractive. Successful markets require independent and even combative standard-setters. The FASB and IASB have been exactly that, cleaning up rules on stock options and pensions, for example, against hostility from special interests. But by giving in to critics now they are inviting pressure to make more concessions.1.Bankers complained that they were forced to(  ).2.According to the author, the rule changes of the FASB may result in (  ).  3.According to Paragraph 4, McCreevy objects to the IASB's attempt to (  ).  4.The author thinks the banks were “on the wrong planet” in that they (  ).  5.The author's attitude towards standard-setters is one of(  ).

Since the days of Aristotle, a search for universal principles has characterized the scientific enterprise. In some ways, this quest for commonalities defines science. Newton's laws of motion and Darwinian evolution each bind a host of different phenomena into a single explicatory frame work. (1)In physics, one approach takes this impulse for unification to its extreme, and seeks a theory of everything—a single generative equation for all we see. It is becoming less clear, however, that such a theory would be a simplification, given the dimensions and universes that it might entail, nonetheless, unification of sorts remains a major goal. This tendency in the natural sciences has long been evident in the social sciences too. (2)Here, Darwinism seems to offer justification for it all humans share common origins it seems reasonable to suppose that cultural diversity could also be traced to more constrained beginnings. Just as the bewildering variety of human courtship rituals might all be considered forms of sexual selection, perhaps the world's languages, music, social and religious customs and even history are governed by universal features. (3)To filter out what is unique from what is shared might enable us to understand how complex cultural behavior arose and what guides it in evolutionary or cognitive terms.That, at least, is the hope. But a comparative study of linguistic traits published online today supplies a reality check. Russell Gray at the University of Auckland and his colleagues consider the evolution of grammars in the light of two previous attempts to find universality in language.The most famous of these efforts was initiated by Noam Chomsky, who suggested that humans are born with an innate language—acquisition capacity that dictates a universal grammar. A few generative rules are then sufficient to unfold the entire fundamental structure of a language, which is why children can learn it so quickly. (4)The second, by Joshua Greenberg, takes a more empirical approach to universality identifying traits (particularly in word order) shared by many language which are considered to represent biases that result from cognitive constraints. Gray and his colleagues have put them to the test by examining four family trees that between them represent more than 2,000 languages. (5)Chomsky's grammar should show patterns of language change that are independent of the family tree or the pathway tracked through it. Whereas Greenbergian universality predicts strong co-dependencies between particular types of word-order relations. Neither of these patterns is borne out by the analysis, suggesting that the structures of the languages are lire age—specific and not governed by universals.

In the 2006 film version of The Devil Wears Prada, Miranda Priestly, played by Meryl Streep, scold her unattractive assistant for imagining that high fashion doesn't affect her. Priestly explains how the deep blue color of the assistant's sweater descended over the years from fashion shows to department stores and to the bargain bin in which the poor girl doubtless found her garment.This top-down conception of the fashion business couldn't be more out of date or at odds with feverish world described in Overdressed, Elizabeth Cline's three-year indictment of “fast fashion”. In the last decades or so, advances in technology have allowed mass-market labels such as Zara, H&M, and Uniqlo to react to trends more quickly and anticipate demand more precisely. Quicker turnarounds mean less wasted inventory, more frequent releases, and more profit. Those labels encourage style-conscious consumers to see clothes as disposable—meant to last only a wash or two, although they don't advertise that—and to renew their wardrobe every few weeks. By offering on-trend items at dirt-cheap prices, Cline argues, these brands have hijacked fashion cycles, shaking an industry long accustomed to a seasonal pace.The victims of this revolution, of course, are not limited to designers. For H&M to offer a $5.95 knit miniskirt in all its 2,300-plus stores around the world, it must rely on low-wage, overseas labor, order in volumes that strain natural resources, and use massive amounts of harmful chemicals.Overdressed is the fashion world's answer to consumer-activist bestsellers like Michael Pollan's The Omnivore’s Dilemma. “Mass-produced clothing, like fast food, fills a hunger and need, yet is non-durable, and wasteful,” Cline argues. Americans, she finds, buy roughly 20 billion garments a year—about 64 items per person—and no matter how much they give away, this excess leads to waste. Towards the end of Overdressed, Cline introduced her ideal, a Brooklyn woman named Sarah Kate Beaumont, who since 2008 has made all of her own clothes—and beautifully. But as Cline is the first to note, it took Beaumont decades to perfect her craft; her example can't be knocked off.Though several fast-fashion companies have made efforts to curb their impact on labor and the environment—including H&M, with its green Conscious Collection Line—Cline believes lasting change can only be effected by the customer. She exhibits the idealism common to many advocates of sustainability, be it in food or in energy. Vanity is a constant; people will only start shopping more sustainably when they can't afford not to.1.Priestly criticizes her assistant for her(  ).2.According to Cline, mass-market labels urge consumers to (  ).  3.The word “indictment” (Line 3, Para.2) is closest in meaning to (  ).  4.Which of the following can be inferred from the last paragraph? 5.What is the subject of the text?

On a five to three vote, the Supreme Court knocked out much of Arizona's immigration law Monday—a modest policy victory for the Obama Administration. But on the more important matter of the Constitution, the decision was an 8-0 defeat for the Administration's effort to upset the balance of power between the federal government and the states.In Arizona v. United States, the majority overturned three of the four contested provisions of Arizona's controversial plan to have state and local police enforce federal immigration law. The Constitutional principles that Washington alone has the power to “establish a uniform Rule of Naturalization” and that federal laws precede state laws are noncontroversial. Arizona had attempted to fashion state policies that ran parallel to the existing federal ones.Justice Anthony Kennedy, joined by Chief Justice John Roberts and the Court's liberals, ruled that the state flew too close to the federal sun. On the overturned provisions the majority held that Congress had deliberately “occupied the field,” and Arizona had thus intruded on the federal's privileged powers.However, the Justices said that Arizona police would be allowed to verify the legal status of people who come in contact with law enforcement. That's because Congress has always envisioned joint federal-state immigration enforcement and explicitly encourages state officers to share information and cooperate with federal colleagues.Two of the three objecting Justice—Samuel Alito and Clarence Thomas—agreed with this Constitutional logic but disagreed about which Arizona rules conflicted with the federal statute. The only major objection came from Justice Antonin Scalia, who offered an even more robust defense of state privileges going back to the Alien and Sedition Acts.The 8-0 objection to President Obama turns on what Justice Samuel Alito describes in his objection as “a shocking assertion of federal executive power”. The White House argued that Arizona's laws conflicted with its enforcement priorities, even if state laws complied with federal statutes to the letter. In effect, the White House claimed that it could invalidate any otherwise legitimate state law that it disagrees with.Some powers do belong exclusively to the federal government, and control of citizenship and the borders is among them. But if Congress wanted to prevent states from using their own resources to check immigration status, it could. It never did so. The administration was in essence asserting that because it didn’t want to carry out Congress's immigration wishes, no state should be allowed to do so either. Every Justice rightly rejected this remarkable claim.1.Three provisions of Arizona's plan were overturned because they(  ).2.On which of the following did the Justices agree, according to Paragraph 4?3.It can be inferred from Paragraph 5 that the Alien and Sedition Acts (  ).  4.The White House claims that its power of enforcement (  ).  5.What can be learned from the last paragraph?

[A]Some archaeological sites have always been easily observable—for example, the Parthenon in Athens, Greece; the pyramids of Giza in Egypt; and the megaliths of Stonehenge in southern England. But these sites are exceptions to the norm. Most archaeological sites have been located by means of careful searching, while many others have been discovered by accident. Olduvai Gorge, an early hominid site in Tanzania, was found by a butterfly hunter who literally fell into its deep valley in 1911. Thousands of Aztec artifacts came to light during the digging of the Mexico City subway in the 1970s.[B]In another case, American archaeologists Rene Million and George Cowgill spent years systematically mapping the entire city of Teotihuacan in the Valley of Mexico near what is now Mexico City. At its peak around AD 600, this city was one of the largest human settlements in the world. The researchers mapped not only the city's vast and ornate ceremonial areas, but also hundreds of simpler apartment complexes where common people lived.[C] How do archaeologists know where to find what they are looking for when there is nothing visible on the surface of the ground? Typically, they survey and sample (make test excavations on) large areas of terrain to determine where excavation will yield useful information. Surveys and test samples have also become important for understanding the larger landscapes that contain archaeological sites.[D] Surveys can cover a single large settlement or entire landscapes. In one case, many researchers working around the ancient Maya city of Copan, Honduras, have located hundreds of small rural villages and individual dwellings by using aerial photographs and by making surveys on foot. The resulting settlement maps show how the distribution and density of the rural population around the city changed dramatically between AD 500 and 850, when Copan collapsed.[E] To find their sites, archaeologists today rely heavily on systematic survey methods and a variety of high-technology tools and techniques. Airborne technologies, such as different types of radar and photographic equipment carried by airplanes or spacecraft, allow archaeologists to learn about what lies beneath the ground without digging. Aerial surveys locate general areas of interest or larger buried features, such as ancient buildings or fields.[F] Most archaeological sites, however, are discovered by archaeologists who have set out to look for them. Such searches can take years. British archaeologist Howard Carter knew that the tomb of the Egyptian pharaoh Tutankhamun existed from information found in other sites. Carter sifted through rubble in the Valley of the Kings for seven years before he located the tomb in 1922. In the late 1800s British archaeologist Sir Arthur Evans combed antique dealers' stores in Athens, Greece. He was searching for tiny engraved seals attributed to the ancient Mycenaean culture that dominated Greece from the 1400s to 1200s BC. Evans's interpretations of these engravings eventually led him to find the Minoan palace at Knossos (Knosos), on the island of Crete, in 1900.[G] Ground surveys allow archaeologists to pinpoint the places where digs will be successful. Most ground surveys involve a lot of walking, looking for surface clues such as small fragments of pottery. They often include a certain amount of digging to test for buried materials at selected points across a landscape. Archaeologists also may locate buried remains by using such technologies as ground radar, magnetic-field recording, and metal detectors. Archaeologists commonly use computers to map sites and the landscapes around sites. Two-and three-dimensional maps are helpful tools in planning excavations, illustrating how sites look, and presenting the results of archaeological research.1.(  )→A→ 2.(  ) →E→ 3.(  ) → 4.(  ) →5.(  )

In the quest for the perfect lawn, homeowners across the country are taking a shortcut—and it is the environment that is paying the price. About eight million square metres of plastic grass is sold each year but opposition has now spread to the highest gardening circles. The Chelsea Flower Show has banned fake grass from this year’s event, declaring it to be not part of its ethos. The Royal Horticultural Society (RHS), which runs the annual show in west London, says it has introduced the ban because of the damage plastic grass does to the environment and biodiversity. Ed Horne, of the RHS, said: “We launched our sustainability strategy last year and fake grass is just not in line with our ethos and views on plastic. We recommend using real grass because of its environmental benefits, which include supporting wildlife alleviating flooding and cooling the environment.” The RHS’s decision comes as campaigners try to raise awareness of the problems fake grass causes. A Twitter account, which claims to “cut through the greenwash” of artificial grass, already has more than 20,000 followers. It is trying to encourage people to sign two petitions, one calling for a ban on the sale of plastic grass and another calling for an “ecological damage” tax on such lawns. They have gathered 7,276 and 11,282 signatures. However, supporters of fake grass point out that there is also an environmental impact with natural lawns, which need mowing and therefore usually consume electricity or petrol. The industry also points out that real grass requires considerable amounts of water, weed killer or other treatments and that people who lay fake grass tend to use their garden more. The industry also claims that people who lay fake grass spend an average of £500 on trees or shrubs for their garden, which provides habitat for insects. In response to another petition last year about banning fake lawns, which gathered 30,000 signatures, the government responded that it has “no plans to ban the use of artificial grass”. It added: “We prefer to help people and organizations make the right choice rather than legislating on such matters. However, the use of artificial grass must comply with the legal and policy safeguards in place to protect biodiversity and ensure sustainable drainage, while measures such as the strengthened biodiversity duty should serve to encourage public authorities to consider sustainable alternatives.1. The RHS thinks that plastic grass ________. 2. The petitions mentioned in Paragraph 3 reveal the campaigners’ ________.3. In Paragraph 4, supporters of fake grass point out ________. 4. What should the government do with regard to artificial grass?5. It can be learned from the text that fake grass ________.

It’s easy to dismiss as absurd the federal government’s ideas for plugging the chronic funding gap of our national parks. Can anyone really think it’s a good idea to allow Amazon deliveries to your tent in Yosemite or food trucks to line up under the redwood trees at Sequoia National Park? But the administration is right about one thing: U.S. national parks are in crisis. Collectively, they have a maintenance backlog of more than $12 billion. Roads, trails, restrooms, visitor centers and other infrastructure are crumbling. But privatizing and commercializing the campgrounds would not be the panacea that the Interior Department’s Outdoor Advisory Committee would have us believe. Campgrounds are a tiny portion of the overall infrastructure backlog, and concessionaires in the parks hand over, on average, only about 5% of their revenues to the National Park Service. Moreover, increased privatization would certainly undercut one of the major reasons why 300 million visitors come to the parks each year: to enjoy nature and get a respite from the commercial drumbeat that overwhelms daily life. The real problem is that the parks have been chronically starved of funding. We conducted a comprehensive survey examining how U.S. residents view their national parks, and we found that Americans place a very high value on them—whether or not they actually visit them. The peer-reviewed economic survey of 700 U.S. taxpayers, conducted by mail and internet, also found that people would be willing to pay a significant amount of money to make sure the parks and their programs are kept intact. Some 81% of respondents said they would be willing to pay additional taxes for the next 10 years to avoid any cuts to the national parks. The national parks provide great value to U.S. residents both as places to escape and as symbols of nature. On top of this, they produce value from their extensive educational programs, their positive impact on the climate through carbon sequestration, their contribution to our cultural and artistic life, and of course through tourism. The parks also help keep America’s past alive, working with thousands of local jurisdictions around the country to protect historical sites—including Ellis Island and Gettysburg—and to bring the stories of these places to life. The parks do all this on a shoestring. Congress allocates only $3 billion a year to the national park system—an amount that has been flat since 2001 (in inflation-adjusted dollars) with the exception of a onetime boost in 2009 as part of the Obama stimulus package. Meanwhile, the number of annual visitors has increased by more than 50% since 1980, and now stands at 330 million visitors per year.1. What problem are U.S. national parks faced with ________. 2. Increased privatization of the campground may ________. 3. According to para. 5, most respondents in the survey would ________. 4. The national parks are valuable in that they ________. 5. It can be concluded from the text that the national park system ________.

The Internet may be changing merely what we remember, not our capacity to do so, suggests Columbia University psychology professor Betsy Sparrow. In 2011, Sparrow led a study in which participants were asked to record 40 factoids in a computer (“an ostrich’s eye is bigger than its brain,” for example). Half of the participants were told the information would be erased, while the other half were told it would be saved. Guess what? The latter group made no effort to recall the information when quizzed on it latter, because they knew they could find it on their computers. In the same study, a group was asked to remember both the information and the folders it was stored in. They didn’t remember the information, but they remembered how to find the folders. In other words, human memory is not deteriorating but “adapting to new communications technology,” Sparrow says.In a very practical way, the Internet is becoming an external hard drive for our memories, a process known as “cognitive offloading.” Traditionally, this role was fulfilled by data banks, libraries, and other humans. Your father may never remember birthdays because your mother does, for instance. Some worry that this is having a destructive effect on society, but Sparrow sees an upside. Perhaps, she suggests, the trend will change our approach to learning from a focus on individual facts and memorization to an emphasis on more conceptual thinking—something that is not available on the Internet. “I personally have never seen all that much intellectual value in memorizing things,” Sparrow says, adding that we haven’t lost our ability to do it.Still other experts say it’s too soon to understand how the Internet affects our brains. There is no experimental evidence showing that it interferes with our ability to focus, for instance, wrote psychologists Christopher Chabris and Daniel Simons. And surfing the web exercised the brain more than reading did among computer-savvy older adults in a 2008 study involving 24 participants at the Semel Institute for Neuroscience and Human Behavior at the University of California, Los Angels.“There may be costs associated with our increased reliance on the Internet, but I’d have to imagine that the overall benefits are going to outweigh those costs,” observes psychology professor Benjamin Storm. “It seems pretty clear that memory is changing, but is it changing for the better? At this point, we don’t know.”1. Sparrow’s study shows that with the Internet, the human brain will ________. 2. The process of “cognitive offloading” ________.3. Which of the following would Sparrow support about the Internet?4. It is indicated in Paragraph 3 that how the Internet affects our brains ________. 5. Neither Sparrow nor Storm would agree that ________.
