单选题{{B}}Passage Three{{/B}} 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. Modern 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 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 interior presents formidable task to the cartographers who undertake the work. Once their labors 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, an 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 intercontinental air service by making these areas as light as day. Present flying routes will completely change, for the Antarctic refueling bases will make flight 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 parties were men who had never seen snow before, and yet he records that they survived the rigors 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 health 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 disease 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 latter 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 years ago was regarded as a "dead continent" now promises to be a most active centre of human life and endeavor.

单选题{{B}}Passage 1{{/B}} The planet's oldest and largest lake, Baikal is about the size of Belgium and accounts for a fifth of the world's fresh water reserves. It is a precious resource, an area of surpassing beauty and to some extent, the very symbol of our nation. For several years, newspapers had been publishing Manning reports on threats to Baikal from industrial construction along its shores, the felling and rafting of timber and pulp mill's discharge of chemical wastes. Documents revealed that Orlov, the prime minister in charge of the paper industry, had ordered construction of a large cellulose complex on the lake's shores to produce a particularly durable rayon cord for airplane tires with the assumption that the pure water would facilitate the chemical process resulting in stronger fibers, and the story goes that Orlov had chosen the site by simply pointing to a place on the shoreline while cruising in a motorboat with some old friends. Tile site, however, turned out to be a seismically active region, and the buildings, while supported by steel piles, are still vulnerable to the major earthquakes that have occurred there once or twice a century. The pure water helped the process, whose final product proved out-of-date, aviation industry switching to metallic cord. The variety of fish, unfortunately, fell victim to the toxic waste, the fragile ecological balance of the region threatened. Those concerned proposed that the lakeshores be closed to new industry and existing enterprises be moved but they encountered tough resistance from officials defending their decision and saving face by insisting on the complex's importance. Of course, what you see on pictures is still a beauty but the lake is no longer a home to more than 1,000 species of plants and animals unknown anywhere else.

单选题So what are books good for? My best answer is that books produce knowledge by encasing it. Books take ideas and set them down, transforming them through the limitations of space into thinking usable by others. In 1959, C. P. Snow threw down the challenge of "two cultures" , the scientific and the humanistic, pursuing their separate, unconnected lives within developed societies. In the new-media ecology of the 21st century, we may not have closed that gap, but the two cultures of the contemporary world are the culture of data and the culture of narrative. Narrative is rarely collective. It isn't infinitely expandable. Narrative has a shape and a temporality, and it ends, just as our lives do. Books tell stories. Scholarly books tell scholarly stories. Storytelling is central to the work of the narrative-driven disciplines—the humanities and the nonquantitative social sciences—and it is central to the communicative pleasures of reading. Even argument is a form of narrative. Different kinds of books are, of course, good for different things. Some should be created only for download and occasional access, as in the case of most reference projects, which these days are born digital or at least given dual passports. But scholarly writing requires narrative fortitude, on the part of writer and reader. There is nothing wiki about the last set of Cambridge University Press monographs(专著)I purchased, and in each I encounter an individual speaking subject. Each single-author book is immensely particular, a story told as only one storyteller could recount it. Scholarship is a collagist(拼贴画家), building the next road map of what we know book by book. Stories end, and that, I think, is a very good thing. A single authorial voice is a kind of performance, with an audience of one at a time, and no performance should outstay its welcome. Because a book must end, it must have a shape, the arc of thought that demonstrates not only the writer's command of her or his subject but also that writer's respect for the reader. A book is its own set of bookends. Even if a book is published in digital form, freed from its materiality, that shaping case of the codex(古书的抄本)is the ghost in the knowledge-machine. We are the case for books. Our bodies hold the capacity to generate thousands of ideas, perhaps even a couple of full-length monographs, and maybe a trade book or two. If we can get them right, books are luminous versions of our ideas, bound by narrative structure so that others can encounter those better, smarter versions of us on the page or screen. Books make the case for us, for the identity of the individual as an embodiment of thinking in the world. The heart of what even scholars do is the endless task of making that world visible again and again by telling stories, complicated and subtle stories that reshape us daily so that new forms of knowledge can shine out.

单选题In this part you are going to read six passages. Each of the passages is followed by some questions or unfinished statements. For each question there are four choices marked A, B, C and D. Decide on the best choice according to the passage you read and write your choice. If you were to examine the birth certificates of every soccer player in 2006's World Cup tournament you would most likely find a noteworthy quirk elite soccer are more likely to have been born in the earlier months of the year than in the later months. If you then examined the European national youth teams that feed the World Cup and professional ranks, you would find this strange phenomenon to be even more pronounced. What might account for this strange phenomenon? Here are a few guesses: a) certain astrological signs confer superior soccer skills, b) winter-born bathes tend to have higher oxygen capacity which increases soccer stamina. c) soccer mad parents are more likely to conceive children in springtime at the annual peak of soccer mania, d) none of the above. Anders Ericsson, a 58-year-old psychology professor at Florida State University, says he believes strongly in "none of the above". Ericsson grew up in Sweden, and studied nuclear engineering until he realized he realized he would have more opportunity to conduct his own research if he switched to psychology. His first experiment nearly years ago, involved memory: training a person to hear and then repeat a random series of numbers. "With the first subject, after about 20 hours of training his digit span had risen from 7 to 20," Ericsson recalls. "He kept improving, and after about 200 hours of training he had risen to over 80 numbers." This success coupled with later research showing that memory itself as not genetically determined, led Ericsson to conclude that the act of memorizing is more of a cognitive exercise than an intuitive one. In other words, whatever inborn differences two people may exhibit in their abilities to memorize those differences are swamped by how well each person "encodes" the information. And the best way to learn how to encode information meaningfully, Ericsson determined, was a process known as deliberate practice. Deliberate practice entails more than simply repeating a task. Rather, it involves setting specific goals, obtaining immediate feedback and concentrating as much on technique as on outcome. Ericsson and his colleagues have thus taken to studying expert performers in a wide range of pursuits, including soccer. They gather all the data they can, not just predominance statistics and biographical details but also the results of their own lavatory experiments with high achievers. Their work makes a rather startling assertion: the trait we commonly call talent is highly overrated. or, put another way, expert performers whether in memory or surgery, ballet or computer programming are nearly always made, not born.

单选题People who question or even look down on the study of the past and its works usually assume that the past is entirely different from the present, and that hence we can learn nothing worthwhile from the past. But it is not true that the past is entirely different from the present. We can learn much of value from its similarity and its difference. A tremendous change in the conditions of human life and in our knowledge and control of the natural world has taken place since ancient times. The ancients could not, however, see in advance our contemporary technical and social environment, and hence have no advice to offer us about the particular problems facing us. But, although social and economic arrangements vary with time and place, man still remains man. We and the ancients share a common human nature and hence certain common human experiences and problems. The poets bear witness that ancient man, too, saw the sun rise and set, felt the wind on his cheek, was possessed by love and desire, experienced joy and excitement as well as frustration and disappointment, and knew good and evil. The ancient poets speak across the centuries to us, sometimes more directly and vividly than our contemporary writers. And the ancient prophets and philosophers, in dealing with the basic problems of men living together in society, still have something to say to us. We also learn from the past by considering the respects in which it differs from the present. We can discover where we are today and what we have become by knowing what the people of the past did and thought. And part of the past—our personal past and that of the race—always lives in us.

单选题Listening out for whale song is one way that ships can avoid colliding with whales. But what do you do if the whales aren't singing? One answer, developed by researchers in the Canary Islands, is to focus on the way the giant creatures mask the clamour of ocean noise. No one knows how many whales are killed by ships each year, but collisions are thought to ac- count for up to a third of unnatural deaths. For the northern right whale, this means one or two individuals every year, and with only 300 animals left, that's an unacceptable loss. There are three global hot spots for whale collisions: northern right whales are at risk in the Atlantic off the east coast of the US and Canada, fin whales in the Mediterranean, and sperm whales off the Canary Islands. Last year, the Massachusetts-based international Fund for Animal Welfare attached hydro- phones to buoys and successfully listened out for right whale song in the North Atlantic. But since right whales remain silent for hours at a time, and sperm whales are silent for around haft the time, a better tracking technology is needed. The new Whale Anti-Collision System (WACS), developed by Michel Andre, is designed to help ships in these hot spots steer clear of the whales. It uses a sonar technique called ambient noise imaging to locate the animals even when they are silent. To do this, Andre has been testing a long lines of buoys, each bristling with 32 sensitive under- water microphones, or hydrophones, that pick up sea sounds such as breaking waves, rain and ship- ping noise. Any approaching whale blocks this background noise and creates a detectable "sound shadow". By comparing the reflections received from the hydrophones on different buoys, Andre's system can gather enough information to work out the whale' s position and how fast it is moving. Software displays the results, on a 3D colour map. Underwater objects stand out like hot spots on a thermal image. In trials planned for next year, Andre will place two lines of 12 spherical buoys along the 120-kilometre ferry route between the islands of Tenerife and Gran Canaria. The signals will be sent to a land station where they will be analysed to create a 3D picture of the sea in real time. If the trials are successful, the WACS software could be installed aboard ferries so that ships' masters can steer clear of whales. Failing that, the whales' movements could be tracked from shore- based installation and radioed to ships in the area.

单选题Hello, my name is Richard and I am an ego surfer. The habit began about five years ago, and now I need help. Like most journalists, I can't deny that one of my private joys is seeing my byline in print. Now the Intemet is allowing me to feed this vanity to an ever greater extent, and the occasional sneaky web search has grown into a full-blown obsession with how high up Google's ranking my articles appear when I put my name into the search box. When I last looked, my best effort was a rather humiliating 47th place. You know you have a problem when you find yourself competing for ranking with a retired basketball player from the 1970s. Not that I'm alone in suffering from a disfunctional techno-habit. New technologies have revealed a whole raft of hitherto unsuspected personality problems: think crackberry, powerpointlessness or cheesepodding. Most of us are familiar with sending an email to a colleague sitting a couple of feet away instead of talking to them. Some go onto the web to snoop on old friends, colleagues or even first dates. More of us than ever reveal highly personal information on blogs or My Space entries. A few will even use Intemet anonymity to fool others into believing they are someone else altogether. So are these web syndromes and technological tics new versions of old afflictions, or are we developing fresh mind bugs? Developing a bad habit is easier than many might think. "You can become addicted to potentially anything you do," says Mark Griffiths, an addiction researcher at Nottingham Trent University in the UK, "because addictions rely on constant rewards." Indeed, although definitions of addiction vary, there is a body of evidence that suggests drug addictions and non-drug habits share the same neural pathways. While only a hardcore few can be considered true technology addicts, an entirely unscientific survey of the web, and of New Scientist staff, has revealed how prevalent techno-addictions may have become. The web in particular has opened up a host of opportunities for overindulgence. Take Wikipedia. Updating the entries--something anyone can do--has become almost a way of life for some. There are more than 2,400 "Wikipedians", who have edited more than 4,000 pages each. "It's clearly like crack for some people," says Dan Closely at Cornell University in New York, who has studied how websites such as Wikipedia foster a community. To committed Wikipedians, he says, the site is more than a useful information resource; it's the embodiment of an ideology of free information for all. Then there are photolog sites like Flickr. While most of us would rather die than be caught surreptitiously browsing through someone else's photos, there need be no such qualms about the private PICS people put up on these sites. Most people using Flickr and similar sites spent time each day browsing albums owned by people they had never met. They do this for emotional kicks. Khalid and Dix suggest: flicking through someone else's wedding photos, for example, allows people to daydream about their own nuptials. Email is another area where things can get out of hand. While email has led to a revival of the habit of penning short notes to friends and acquaintances, the ease with which we can do this means that we don't always think hard enough about where our casual comments could end up. This was the undoing of US broadcaster Keith Olbermann,who earlier this year sent a private email in which he described a fellow MSNBC reporter as "dumber than a suitcase of rocks". Unfortunately for Olbermann, the words found their way into the New York Daily News. Pam Briggs, a specialist in human-computer interaction at the University of Northumbria, UK, says the lack of cues such as facial expressions or body language when communicating electronically can lead us to overcompensate in what we say. "The medium is so thin, there's little room for projecting ourselves into it," says Briggs. "When all the social cues disappear, we feel we have to put something else into the void, which is often an overemotional or over-intimate message." The habit of forwarding jokey emails or YouTube videos- think Diet Coke and Mentos fountains- can also say a lot about how people want to be perceived, Briggs adds. "We rarely want to be seen as too serious, so we try to project more of our personality into email." This could also explain why many bloggers expose private information that they would never shout out to a crowded room.
