单选题The Month of January offered those who track the ups and downs of the U. S. economy 92 significant data releases and announcements to digest. That's according to a calendar compiled by the investment bank UBS. The number doesn't include corporate earnings, data from abroad or informal indicators like, say, cardboard prices (a favorite of Alan Greenspan's back in the day). It was not always thus. "One reads with dismay of Presidents Hoover and then Roosevelt designing policies to combat the Great Depression of the 1930s on the basis of such sketchy data as stock price indices, freight car loadings, and incomplete indices of industrial production," writes the University of North Carolina's Richard Froyen in his macroeconomics textbook. But that was then The Depression inspired the creation of new measures like gross domestic product. (It was gross national product back in those days, but the basic idea is the same. ) Wartime planning needs and advances in statistical techniques led to another big round of data improvements in the 1940s. And in recent decades, private firms and associations aiming to serve the investment community have added lots of reports and indexes of their owrL Taken as a whole, this profusion of data surely has increased our understanding of the economy and its ebb and flow. It doesn't seem to have made us any better at predicting the future, though; perhaps that would be too much to ask But what is troubling at a time like this, with the economy on everyone's mind, is how misleading many economic indicators can be about the present. Consider GDP. In October, the Commerce Department announced--to rejoicing in the media, on Wall Street and in the White House--that the economy had grown at a 3.5% annual pace in the third quarter. By late December, GDP had been revised downward to a less impressive 2.2%, and revisions to come could ratchet it down even more (or revise it back up). The first fourth-quarter GDP estimate comes out Jan. 29. Some are saying it could top 5%. If it does, should we really believe it? Or take jobs. In early December, the Labor Department's monthly report surprised on the upside-- and brought lots of upbeat headlines--with employers reporting only 11, 000 jobs lost and the unemployment rate dropping from 10.2% to 10%. A month later, the surprise was in the other directio--unemployment has held steady, but employers reported 85,000 fewer jobs. Suddenly the headlines were downbeat, and pundits were pontification about the political implications of a stalled labor market. Chances are, the disparity between the two reports was mostly statistical noise. Those who read great meaning into either were deceiving themselves. It's a classic case of information overload making it harder to see the trends and patterns that matter. In other words, we might be better off paying less (or at least less frequent) attention to data. With that in mind, I asked a few of my favorite economic forecasters to name an indicator or two that I could afford to start ignoring. Three said they disregarded the index of leading indicators, originally devised at the Commerce Department but now compiled by the Conference Board, a business group. Forecasters want new hard data, and the index "consists entirely of already released information and the Conference Board's forecasts," says Jan Hatzius of Goldman Sachs. (The leading-indicators index topped a similar survey by the Chicago Tribune in 2005, it turns out. ) The monthly employment estimate put out by pay roll-service firm ADP got two demerits, mainly because it doesn't do a great job of predicting the Labor Department employment numbers that are released two days later. And consumer-sentiment indexes, which offer the tantalizing prospect of predicting future spending patterns but often function more like an echo chamber, got the thumbs-down from two more forecasters. The thing is, I already ignore all these (relatively minor) indicators. I had been hoping to learn I could skip GDP or the employment report. I should have known that professional forecaster wouldn't forgo real data. As Mark Zandi of Moody's Economy. com put it in an e-mail, "I cherish all economic indicators. " Most of us aren't professional forecasters. What should we make of the cacophony of monthly and weekly data? The obvious advice is to focus on trends and ignore the noise. But the most important economic moments come when trends reverse--when what appears to be noise is really a sign that the world has changed. Which is why, in these uncertain times, we jump whenever a new economic number comes out. Even one that will be revised in a month.

单选题Every day of our lives we are in danger of instant death from small high-speed missiles from space—the lumps of rocky or metallic debris which continuously bombard the Earth. The chances of anyone actually being hit, however, are very low, although there are recorded instances of "stones from the sky" hurting people, and numerous accounts of damage to buildings and other objects. At night this extraterrestrial material can be seen as "fireballs" or "shooting stars", burning their way through our atmosphere. Most, on reaching our atmosphere, become completely vaporised. The height above ground at which these objects become sufficiently heated to be visible is estimated to be about 60-100 miles. Meteorites that have fallen on buildings have sometimes ended their long lonely space voyage incongruously under beds, inside flower pots or even, in the case of one that landed on a hotel in North Wales, within a chamber pot. Before the era of space exploration it was confidently predicted that neither men nor space vehicles would survive for long outside the protective blanket of the Earth"s atmosphere. It was, thought that once in space they would be seriously damaged as a result of the incessant downpour of meteorites falling towards our planet at the rate of many millions every day. Even the first satellites showed that the danger from meteorites had been greatly overestimated by the pessimists, but although it has not happened yet, it is certain that one day a spacecraft will be badly damaged by a meteorite. The greatest single potential danger to life on Earth undoubtedly comes from outside our planet. Collision with another astronomical body of any size or with a "black hole" could completely destroy the Earth almost instantly. Near misses of bodies larger than or comparable in size to our own planet could be equally disastrous to mankind as they might still result in total or partial disruption. If the velocity of impact were high, collision with even quite small extraterrestrial bodies might cause catastrophic damage to the Earth"s atmosphere, oceans and outer crust and thus produce results inimical to life as we know it. The probability of collision with a large astronomical body from outside our Solar System is extremely low, possibly less than once in the lifetime of an average star. We know, however, that our galaxy contains great interstellar dust clouds and some astronomers have suggested that there might also be immense streams of meteorite matter in space that the Solar system may occasionally encounter. Even if we disregard this possibility, our own Solar system itself contains a great number of small astronomical bodies, such as the minor planets or asteroids and the comets, some with eccentric orbits that occasionally bring them close to the Earth"s path.

单选题 Questions 16-20 Computers monitor everything in Singapore from soil composition to location of manholes. At the airport, it took just 15 seconds for the computerized immigration system to scan and approve my passport. It takes only one minute to be checked into a public hospital. By 1998, almost every household will be wired for interactive cable TV and the Internet, the global computer network. Shoppers will be able to view and pay for products electronically. A 24- hour community telecomputing network will allow users to communicate with elected representatives and retrieve information about government services. It is all part of the government's plan to transform the nation into what it calls the "Intelligent Island". In so many ways, Singapore has elevated the concept of efficiency to a kind of national ideology. For the past ten years, Singapore's work force was rated the best in the world--ahead of Japan and the U. S. --in terms of productivity, skill and attitude by the Business Environment Risk Intelligence service. Behind the "Singapore miracle" is a man Richard Nixon described as one of "the ablest leaders I have met," one who, "in other times and other places, might have attained the world stature of a Churchill. " Lee Kuan Yew led Singapore's struggle for independence in the 1950s, serving as Prime Minister from 1959 until 1990. Today (1995), at 71, he has nominally retired to the office of Senior Minister, where he continues to influence his country's future. Lee offered companies tax breaks, political stability, cheap labor and strike-free environment. Nearly 90 percent of Singaporean adults now own their own homes and thanks to strict adherence to the principle of merit, personal opportunities abound. "If you've got talent and work hard, you can be anything here," says a Malaysian-born woman who holds a high-level civil-service position. Lee likes to boast that Singapore has avoided the "moral breakdown" of Western countries. He attributes his nation's success to strong family ties, a reliance on education as the engine of advancement and social philosophy that he claims is superior to America's. In an interview with Reader's Digest, he said that the United States has "lost its bearings" by emphasizing individual rights at the expense of society. "An ethical society," he said, "is one which matches human rights with responsibilities. "

单选题Psychologists agree that I.Q. contributes only about 20% of the factors that determine success. A full 80% comes from other factors, including what I call emotional intelligence. Following are two of the major qualities that make up emotional intelligence, and how they can be developed: Self-awareness The ability to recognize a feeling as it happens is the keystone of emotional intelligence. People with greater certainty about their emotions are better pilots of their lives. Developing self-awareness requires tuning in to what neurologist Antonio Damasio calls "gut feelings". Gut feelings can occur without a person being consciously aware of them. For example, when people who fear snakes are shown a picture of a snake, sensors on their skin will detects sweat, a sign of anxiety, even though the people say they do not feel fear. The sweat shows up even when a picture is presented so rapidly that the subject has no conscious awareness of seeing it. Through deliberate effort we can become more aware of our gut feelings. Take someone who is annoyed by a rude encounter for hours after it occurred. He may be unaware of his irritability and surprised when someone calls attention to it. But if he evaluates his feelings, he can change them. Emotional self-awareness is the building block of the next fundamental of emotional intelligence: being able to shake off a bad mood. Mood Management Bad as well as good moods spice life and build character. The key is balance. We often have little control over when we are swept by emotion. But we can have some say in how long that emotion will last. Psychologist Dianne Tice asked more than 400 men and women about their strategies for escaping foul moods. Her research, along with that of other psychologists, provides valuable information on how to change a bad mood. Of all the moods that people want to escape, rage seems to be the hardest to deal with. When someone in another car eats you off on the highway, your reflexive thought may be: That jerk! He could have hit me! I can"t let him get away with that! The more you stew, the angrier you get. Such is the stuff of hypertension and reckless driving. What should you do to relieve rage? One myth is that ventilating will make you feel better. In fact, researchers had found that"s one of the worst strategies. A more effective technique is "reframing", which means consciously reinterpreting a situation in a more positive light. In the case of the driver who cuts you off, you might tell yourself: Maybe he had some emergency. This is one of the most potent ways, Tice found, to put anger to rest. Going off alone to cool down is also an effective way to refuse anger, especially if you can"t think clearly. Tice found that a large proportion of men cool down by going for a drive—a finding that inspired him to drive more defensively. A safer alternative is exercise, such as taking a long walk. Whatever you do, don’t waste the time pursuing your train of angry thoughts. Your aim should be to distract yourself. The techniques of reframing and distraction can alleviate depression and anxiety as well as anger. Add to them such relaxation techniques as deep breathing and meditation and you have an arsenal of weapons against bad moods.

单选题There"s a new campaign for the under-30s called Undivided. It gathers suggestions about Brexit from across the spectrum: leavers and remainers, left and, presumably, right. Its aim is to "get the best possible deal for young people out of the Brexit negotiations" and it will present the chosen ten demands in January. Hafsah Dabiri, its co-leader, says that young people must have a voice, and "the only way to achieve this is for us to be undivided in our political demands". Ah, demands. When a news website published Undivided"s video of young people speaking to camera, a sort of digital Ed Stone in its vagueness, the D-word was central. "I demand that there will be structures in place that allow me to study and work in Europe"; "I demand better access to mental health services for young people and better sexual health services for young women"; "I demand maintenance of free travel and free trade following Brexit". They must call the shots because they "are going to live with the consequences of Brexit the longest". The presumption that anyone over 30 is going to die soon may be a bit wounding to some of us, but never mind. It goes on to demand that Islamophobia and racism are stamped out, and "young people are finally taken seriously". Friends, this is not the way to get taken seriously by us battered, moribund, doomed oldies. Scroll down and the first reactions are tart. "I demand they learn manners, and how to vote" and "Oh, piss off, you can demand nothing, go sit in the corner and learn some manners...try thanking the older generation who fought to give them freedom of speech". To be fair, regarding that last comment the generation who fought most relevantly are now gently passing into history. The legitimate generational quarrel is with us baby-boomers who surfed a wave of prosperity, let the European dream corrode into corrupt bureaucracy, and didn"t mend the roof while the sun shone. Undivided is welcome because the young should be idealistic and take an interest. But reflecting on that intensely annoying video it struck me that if they have learnt the language of entitlement and demand it was from the generation above. Active citizenship, constructive improvement and neighbourly grassroots organization have declined in status and esteem. The industrious wartime sense of a duty to save, firewatch and donate scrap iron to the common good is old hat. We have created a sense of the citizen as disgruntled recipient, not active contributor. Of course from ministries to minnows, active citizens still beaver away, keep the wheels turning and struggle to meet demands. But rarely does anybody say: "A good job done. Thank you!" Rather, the tone of public discourse is a passive and critical one: "Why-can"t-I"; "S-not fair"; "Bloody jobsworths". Hands up: this is led by media. A soggy stream of unconstructive passive discontent and crabby criticism rises constantly from interviews and polemics, comedians, columnists and Twitter. Excuse me here while I shoot myself in the foot and irritate the hell out of my colleagues, but if I read one more beautifully phrased think piece (even by me) about how "the government is doing Brexit all wrong, and, dammit, not even telling us what it is doing, but we assume it"s rubbish"—I shall scream. The same goes for the routine sneer of the newscast interviewer and the grunting outrage of the polemicist. It"s great entertainment, this universal barracking. But anyone who has ever sat around a committee table knows what a sweat it is to balance budgets, comply with laws, set priorities, delay cherished projects, cheesepare costs and—yes—worry about media reaction. Yet those who do this rarely get much credit. In an age when media and image are sublime, the most popular figures are deplorers and snarkers who mock and complain and "demand". The palm of public approval goes to comedians and commentators, interviewers and satirists and entertainers who publicly weep for their nation"s shame. Some people, of course, do both. Honour to fundraisers, charity stalwarts, aid workers, and honest souls who stir their stumps to man a food bank, create non-profit services, take clothes and food to the homeless or the Calais Jungle. They I admire. They can have a platform. Among the "Undivided" campaigners some of the young demanders probably are volunteering, or thinking of how to engage with Europe or whatever. Those are fully entitled to offer well-researched and detailed "demands" and also to inform us, the media, so we can admiringly report and support them. But let it always be clear, in everyone"s mind, that anyone who actually does things for the general good deserves a higher rank and esteem than anyone who just talks about it. Or mocks it. There"s a parallel in the principle, which all sensible critics admit, that any honest theatre-maker or writer or creative artist—even if unsuccessful—outranks any critic, however brilliant. Actions speak louder than words. Not the other way round.

单选题Jamie Stephenson has seen firsthand what modem genetic science can do for a family. When her son David was 2 years old, a pediatrician noticed developmental delays and suspected fragile syndrome, a hereditary form of mental retardation. A lab test confirmed the diagnosis, and the Stephensons spent several years learning to live with it. When David was 6, he visited a neurologist, who scribbled "fragile X" on an insurance-company claim form. The company responded promptly—by canceling coverage for the entire family of six. There is no medical treatment for fragile X, and none of David"s siblings had been diagnosed with the condition. "The company didn"t care," Stephenson says. "They just saw a positive genetic test and said, "You"re out". " From the dawn of the DNA era, critics have worried that genetic testing would create a "biological underclass"—a population of people whose genes brand them as poor risks for employment, insurance, even marriage. The future is arriving fast. Medical labs can now test human cells for hundreds of anomalous genes. Besides tracking rare conditions, some firms now gauge people"s susceptibility to more common scourges. By unmasking inherited mutations in p53 ( main story) and other, genes, the new tests can signal increased risk of everything from breast, colon and prostate tumors to leukemia. Many of the tests are still too costly for mass marketing, but that will change. And as the Stephensons" story suggests, the consequences won"t all be benign. "This is bigger than race or sexual orientation," says Martha Volner, health-policy director for the Alliance of Genetic Support Groups. "Genetic discrimination is the civil-rights issue of the 21st century." No one would argue that genetic tests are worthless. Used properly, they can give people unprecedented power over their lives. Prospective parents who discover they"re silent carriers of the gene for a disease can make better-in formed decisions about whether and how to have kids. Some genetic maladies can be managed through medication and lifestyle changes once they"re identified. And while knowing that you"re at special risk for cancer may be an emotional burden, it can also alert you to the need for intensive monitoring. Jane Gorrell knows her family is prone to colon cancer. Her father developed hundreds of precancerous polyps back in the 1960s, and both she and her sister had the same experience during the "70s. Their condition, has since been linked to a mutation in the p53 gene—and Gorrell has learned, that one of her two children inherited it. Though the child has suffered no symptoms, she gets frequent colon exams and is helping researchers test a drug that could help save lives. The catch is that no one can guarantee the privacy of genetic information. Outside of large group plans, insurance companies often scour people"s medical records before extending coverage. And though employers face some restriction, virtually any company with a benefits program can get access to workers" health data. So can schools, adoption agencies and the military. Employees of Lawrence Berkeley Laboratory (LBL), a large research institution owned by the Department of Energy and operated by the University of California, recently discovered that the organization had for three decades been quietly testing new hires blood and urine samples for evidence of various conditions. "I can"t say the information was put to some incredibly harmful use, because we don"t know what happened," says Vicki Laden, a San Francisco lawyer who has tried unsuccessfully to sue the lab for civil fights violations. LBL recently stopped the testing.

单选题Questions 16 to 20 are based on the following talk.

单选题 Is language, like food, a basic human need without which a child at a critical period of life can be starved and damaged? Judging from the drastic experiment of Frederick Ⅱ in the thirteenth century, it may be. Hoping to discover what language a child would speak if he heard no mother tongue, he told the nurses to keep silent. All the infants died before the first year. But clearly there was more than lack of language here. What was missing was good mothering. Without good mothering, in the first year of life especially, the capacity to survive is seriously affected. Today no such severe lack exists as that ordered by Frederick. Nevertheless, some children are still backward in speaking. Most often the reason for this is that the mother is insensitive to the signals of the infant, whose brain is programmed to learn language rapidly. If these sensitive periods are neglected, the ideal time for acquiring skills passes and they might never be learned so easily again. A bird learns to sing and to fly rapidly at the right time, but the process is slow and hard once the critical stage has passed. Experts suggest that speech stages are reached in a fixed sequence and at a constant age, but there are cases where speech has started late in a child who eventually turns out to be of high IQ. At twelve weeks a baby smiles and makes vowel-like sounds; at twelve months he can speak simple words and understand simple commands; at eighteen months he has a vocabulary of three to fifty words. At three he knows about 1,000 words which he can put into sentences, and at four his language differs from that of his parents in style rather than grammar. Recent evidence suggests that an infant is born with the capacity to speak. What is special about man's brain, compared with that of the monkey, is the complex system which enables a child to connect the sight and feel of, say, a toy-bear with the sound pattern "toy-bear". And even more incredible is the young brain's ability to pick out an order in language from the mixture of sound around him, to analyze, to combine and recombine the parts of a language in new ways. But speech has to be induced, and this depends on interaction between the mother and the child, where the mother recognizes the signals in the child's babbling, grasping and smiling, and responds to them. Insensitivity of the mother to these signals dulls the interaction because the child gets discouraged and sends out only the obvious signals. Sensitivity to the child's non-verbal signals is essential to the growth and development of language.

单选题 Wild Bill Donovan would have loved the Internet. The American spymaster who built the Office of Strategic Services in the World War II and later laid the roots for the CIA was fascinated with information. Donovan believed in using whatever tools came to hand in the "great game" of espionage—spying as a "profession". These days the Net, which has already re-made pastimes as buying books and sending mail, is reshaping Donovan's vocation as well. The last revolution isn't simply a matter of gentlemen reading other gentlemen's e-mail. That kind of electronic spying has been going on for decades. In the past three or four years, the World Wide Web has given birth to a whole industry of point-and-click spying. The technical talents call it "open source intelligence", and as the Net grows, it is becoming increasingly influential. In 1995 the CIA held a contest to see who could compile the most data about Burundi. The winner, by a large margin, was a tiny Virginia company called Open-Source Solutions, whose clear advantage was its mastery of the electronic world. Among the firms making the biggest splash in the new world is Straitford Inc., a private intelligence-analysis firm based in Austin, Texas. Straitford makes money by selling the results of spying (covering nations from Chile to Russia) to corporations like energy-services firm McDermott International. Many of its predictions are available online at www. straitford, com. Straitford president George Friedman says he sees the online world as a kind of mutually reinforcing tool for both information collection and distribution, a spymaster's dream. Last week his firm was busy vacuuming up data bits from the far comers of the world and predicting a crisis in Ukraine. "As soon as that report nms, we'll suddenly get 500 new Internet sign-ups from Ukraine," says Friedman, a former political science professor. "And we'll hear back from some of them." Open-source spying does have its risks, of course, since it can be difficult to tell good information from bad. That's where Straitford earns its keep. Friedman relies on a lean staff in Austin. Several of his staff members have military-intelligence backgrounds. He sees the firm's outsider status as the key to its success. Straitford's briefs don't sound like the usual Washington back-and-forthing, whereby agencies avoid dramatic declarations on the chance they might be wrong. Straitford, says Friedman, takes pride in its independent voice.

单选题 What, can rigid, cold calculating mathematics possibly have in common with subtle, creative, lofty, imaginative art? This question faithfully mirrors the state of mind of most people, even of most educated people, when they regard the numbers and symbols that populate the world of mathematics. But the great leaders of mathematics thought have frequently and repeatedly asserted that the object of their pursuit is just as much an art as it is a science, and perhaps even a fine art. Maxime Bocher, an eminent mathematician living at the beginning of this century, wrote: "I like to look at mathematics almost more as an art than as a science; for the activity of the mathematician, constantly creating as he is, guided although not controlled by the external world of the senses, bears a resemblance, not fanciful, I believe, but real, to the activities of the artist—of a painter, let us say." Rigorous deductive reasoning on the part of the mathematician may be likened here to the technical skill in drawing on the part of the painter. Just as one cannot become a painter without a certain amount of skill, so no one can become a mathematician without the power to reason accurately up to a certain point. "Yet these qualities, fundamental though they are, do not make a painter or a mathematician worthy of the name, nor indeed are they the most important factors in the case. Other qualities of a far more subtle sort, chief among which in both cases is imagination, go into the making of a good artist or a good mathematician." If mathematics wants to lay claim to being an art, however, it most shows that it possesses and makes use of at least some of the elements that go to make up the things of beauty. Is not imagination, creative imagination, the most essential element of an art? Let us take a geometric object, such as the circle. To the ordinary man, this is the rim of a wheel, perhaps with spokes in it. Elementary geometry has crowded this simple figure with radii, chords, sectors, tangents, diameters, inscribed and circumscribed polygons, and so on. Here you have already an entire geometrical world created from a very rudimentary beginning. These and other miracles are undeniable proof of the creative power of the mathematieian; and, as if this were not enough, the mathematician allows the whole circle to "vanish", declares it to be imaginary, then keeps on toying with his new creation in much the same way and with much the same gusto as he did with the innocent little thing you allowed him to start out with. And all this, remember please, is just elementary plane geometry. Truly, the creative imagination displayed by the mathematician has nowhere been exceeded, not even paralleled, and, I would make bold to say, now even closely approached anywhere else. In many ways mathematics exhibits the same elements of beauty that are generally acknowledged to be the essence of poetry. First let us consider a minor point: the poet arranges his writings on the page in verses. His poem first appeals to the eye before it reaches the ear or the mind; and similarly, the mathematician lines up his 'formulas and equations so that their form may make an aesthetic impression. Some mathematicians are given to this love of arranging and exhibiting their equations to a degree that borders on a fault. Trigonometry, a branch of elementary mathematics particularly rich in formulas, offers some curious groups of them, curious in their symmetry and their arrangement. The superiority of poetry over other forms of verbal expression lies first in the symbolism used in poetry, and secondly in its extreme condensation and economy of words. Take a poem of universally acknowledged merit, say, Shelley's poem "To Night". Here is the second stanza: Wrap thy form in a mantle gray, star-in wrought! Blind with thine hair the eyes of Day; Kiss her until she be wearied out; Then wander oer city, and sea, and land, Touching all with thine opiate wand—Come, long-sought ! Taken literally, all this is, of course, sheer nonsense and nothing else. Night has no hair, night does not wear any clothes, and night is not an illicit peddler of narcotics. But is there anybody balmy enough to take the words of the poet literally? The words here are only comparisons, only symbols. For the sake of condensation the poet doesn't bother stating that his symbols mean such and such, but goes on to treat them as if they were realities. The mathematician does these things precisely as the poet does. Take numbers, for example, the very idea of which is an abstraction, or symbol. When you write the figure 3, you have created a symbol for a symbol, and when you say in algebra that is a number, you have condensed all the symbols for all the numbers into one all-embracing symbol. These, like other mathematical symbols, and like the poets symbols, are a condensed, concentrated way of stating a long and rather complicated chain of simple geometrical, algebraic, or numerical relations.

单选题Questions 16 to 20 are based on the following talk.

单选题 Civil-liberties advocates reeling from the recent revelations on surveillance had something else to worry about last week: the privacy of the billions of search queries made on sites like Google, AOL, Yahoo and Microsoft. As part of a long-running court case, the government has asked those companies to turn over information on its users' search behavior. All but Google have handed over data, and now the Department of Justice has moved to compel the search giant to turn over the goods. What makes this case different is that the intended use of the information is not related to national security, but the government's continuing attempt to police Internet pornography. In 1998, Congress passed the Child Online Protection Act (COPA), but courts have blocked its implementation due to First Amendment concerns. In its appeal, the DOJ wants to prove how easy it is to inadvertently stumble upon porn. In order to conduct a controlled experiment—to be performed by a UC Berkeley professor of statistics—the DOJ wants to use a large sample of actual search terms from the different search engines. It would then use those terms to do its own searches, employing the different kinds of filters each search engine offers, in an attempt to quantify how often "material that is harmful to minors" might appear. Google contends that since it is not a party to the case, the government has no right to demand its proprietary information to perform its test. "We intend to resist their motion vigorously," said Google attorney Nicole Wong. DOJ spokesperson Charles Miller says that the government is requesting only the actual search terms, and not anything that would link the queries to those who made them. (The DOJ is also demanding a list of a million Web sites that Google indexes to determine the degree to which objectionable sites are searched.) Originally, the government asked for a treasure trove of all searches made in June and July 2005; the request has been scaled back to one week's worth of search queries. One oddity about the DOJ's strategy is that the experiment could conceivably sink its own case. If the built-in filters that each search engine provides are effective in blocking porn sites, the government will have wound up proving what the opposition has said all along—you don't need to suppress speech to protect minors on the Net. "We think that our filtering technology does a good job protecting minors from inadvertently seeing adult content," says Ramez Naam, group program manager of MSN Search. Though the government intends to use these data specifically for its COPA-related test, it's possible that the information could lead to further investigations and, perhaps, subpoenas to find out who was doing the searching. What if certain search terms indicated that people were contemplating terrorist actions or other criminal activities? Says the DOJ's Miller, "I'm assuming that if something raised alarms, we would hand it over to the proper [authorities]." Privacy advocates fear that if the government request is upheld, it will open the door to further government examination of search behavior. One solution would be for Google to stop storing the information, but the company hopes to eventually use the personal information of consenting customers to improve search performance. "Search is a window into people's personalities," says Kurt Opsahl, an Electronic Frontier Foundation attorney. "They should be able to take advantage of the Internet without worrying about Big Brother looking over their shoulders. "

单选题 The discovery of the Antarctic not only proved one of the most interesting of all geographical adventures, but created what might be called "the heroic age of Antarctic exploration". By their tremendous heroism, men such as Shackleton, Scott, and Amundsen, caused a new continent to emerge from the shadows, and yet that heroic age, little more than a century old, is already passing. Modem science and inventions are revolutionizing the techniques of former explorers, and, although still calling for courage and feats of endurance, future journeys into these icy wastes will probably depend on motor vehicles equipped with caterpillar traction rather than on the dogs that earlier discoverers found so invaluable. Few realize that this Antarctic continent is almost equal in size to South America, and an enormous field of work awaits geographers and prospectors. The coasts of this continent remain to be accurately charted, and the mapping of the whole of the interior presents a formidable task to the cartographers who undertake the Work. Once their labours are completed, it will be possible to prospect the vast natural resources which scientists believe will furnish one of the largest treasure hoards of metals and minerals the world has yet known, and almost inexhaustible sources of copper, coal, uranium, and many other ores will become available to man. Such discoveries will usher in an era of practical exploitation of the Antarctic wastes. The polar darkness which hides this continent for the six winter months will be defeated by huge batteries of light, and make possible the establishing of air-fields for the future inter-continental air services by making these areas as light as day, Present flying mutes will be completely changed, for the Antarctic refueling bases will make flights from Australia to South America comparatively easy over the 5,000 miles journey. The climate is not likely to offer an insuperable problem, for the explorer Admiral Byrd has shown that the climate is possible even for men completely untrained for expeditions into those frozen wastes. Some of his party were men who had never seen snow before, and yet he records that they survived the rigours of the Antarctic climate comfortably, so that, provided that the appropriate installations are made, we may assume that human beings from all countries could live there safely. Byrd even affirms that it is probably the most healthy climate in the world, for the intense cold of thousands of years has sterilized this continent, and rendered it absolutely germfree, with the consequences that ordinary and extraordinary sicknesses and diseases from which man suffers in other zones with different climates are here utterly unknown. There exist no problems of conservation and preservation of food supplies, for the later keep indefinitely without any signs of deterioration; it may even be that later generations will come to regard the Antarctic as the natural storehouse for the whole world. Plans are already on foot to set up permanent bases on the shores of this continent, and what so few yearn ago was regarded as a "dead continent" now promises to be a most active center of human life and endeavour.
