单选题Extraordinary creative activity has been characterized as revolutionary, flying in the face of what is established and producing not what is acceptable but what will become accepted. According to this formulation, highly creative activity transcends the limits of an existing form and establishes a new principle of organization. However, the idea that extraordinary creativity transcends established limits is misleading when it is applied to the arts, even though it may be valid for the sciences. Differences between highly creative art and highly creative science arise in part from a difference in their goals. For the sciences, a new theory is the goal and end result of the creative act. Innovative science produces new propositions in terms of which diverse phenomena can be related to one another in more coherent ways. Such phenomena as a brilliant diamond or a nesting bird are relegated to the role of data, serving as the means for formulating or testing a new theory. The goal of highly creative art is very different: the phenomenon itself becomes the direct product of the creative act. Shakespeare' s Hamlet is not a tract about the behavior of indecisive princes or the uses of political power, nor is Picasso' s painting Guernica primarily a propositional statement about the Spanish Civil War or the evils of fascism. What highly creative artistic activity produces is not a new generalization that transcends established limits, but rather an aesthetic particular. Aesthetic particulars produced by the highly creative artist extend or exploit, in an innovative way, the limits of an existing form, rather than transcend that form. This is not to deny that a highly creative artist sometimes establishes a new principle of organization in the history of an artistic field; the composer Monteverdi, who created music of the highest aesthetic value, comes to mind. More generally, however, whether or not a composition establishes a new principle in the history of music has little bearing on its aesthetic worth. Because they embody a new principle of organization, some musical works, such as the operas of Florentine Cnmerata, are of signal historical importance, but few listeners or musicologists would include these among the great works of music. On the other hand, Mozart' s The Marriage of Figaro is surely among the masterpieces of music even though its modest innovations are confined to extending means. It bas been said of Beethoven that he toppled the rules and freed music from the stifling confines of convention. But a close study of his compositions reveals that Beethoven overturned no fundamental rules. Rather, he was an incomparable strategist who exploited limits— the rules, forms, and conventions that he inherited from predecessors such as taydn and Mozart, Handel and Bach—in strikingly original ways.

单选题The human brain contains 10 thousand million cells and each of these may have a thousand connections. Such enormous numbers used to discourage us and cause us to dismiss the possibility of making a machine with human-like ability, but now that we have grown used to moving forward at such a pace we can be less sure. Quite soon, in only 10 or 20 years perhaps, we will be able to assemble a machine as complex as the human brain, and if we can we will. It may then take us a long time to render it intelligent by loading in the right software or by altering the architecture but that, too, will happen. I think it certain that in decades, not centuries, machines of silicon will arise first to rival and then exceed, their human ancestors. Once they exceed us they will be capable of their own design. In a real sense they will be able to reproduce themselves. Silicon will have ended carbon's long control. And we will no longer be able to claim ourselves to be the finest intelligence in the known universe. As the intelligence of robots increases to match that of humans and as their cost declines through economies of scale we may use them to expand our frontiers, first on earth through their ability to withstand environments harmful to ourselves. Thus, deserts may bloom and the ocean beds be mined. Further ahead, by a combination of the great wealth this new age will bring and the technology it will provide, the construction of a vast, man-created world in space, home to thousands of millions of people, will be within our power.

单选题Some of the concerns surrounding Turkey's application to join the European Union, to be voted on by the EU's Council of Ministers on December 17th, are economic — in particular, the country's relative poverty. Its GDP per head is less than a third of the average for the 15 pre-2004 members of the EU. But it is not far off that of one of the ten new members which joined on May 1st 2004(Latvia), and it is much the same as those of two countries, Bulgaria and Romania, which this week concluded accession talks with the EU that could make them full members on January 1st 2007. Furthermore, the country's recent economic progress has been, according to Donald Johnston, the secretary-general of the OECD, " stunning". GDP in the second quarter of the year was 13. 4% higher than a year earlier, a rate of growth that no EU country comes close to matching. Turkey's inflation rate has just fallen into single figures for the first time since 1972, and this week the country reached agreement with the IMF on a new three-year, $ 10 billion economic programme that will, according to the IMF's managing director, Rodrigo Rato, "help Turkey... reduce inflation toward European levels, and enhance the economy's resilience". Resilience has not historically been the country's economic strong point. As recently as 2001, GDP fell by over 7% . It fell by more than 5% in 1994, and by just under 5% in 1999. Indeed, throughout the 1990s growth oscillated like an electrocardiogram recording a violent heart attack. This irregularity has been one of the main reasons(along with red tape and corruption)why the country has failed dismally to attract much-needed foreign direct investment. Its stock of such investment(as a percentage of GDP)is lower now than it was in the 1980s, and annual inflows have scarcely ever reached $ 1 billion(whereas Ireland attracted over $ 25 billion in 2003, as did Brazil in every year from 1998 to 2000). One deterrent to foreign investors is due to disappear on January 1st 2005. On that day, Turkey will take away the right of virtually every one of its citizens to call themselves a millionaire. Six noughts will be removed from the face value of the lira; one unit of the local currency will henceforth be worth what lm are now—ie, about 0. 53euro($ 0. 70). Goods will have to be priced in both the new and old lira for the whole of the year, but foreign bankers and investors can begin to look forward to a time in Turkey when they will no longer have to juggle mentally with indeterminate strings of zeros.

单选题We tend to think of the decades immediately following World War Ⅱ as a time of prosperity and growth, with soldiers returning home by the millions, going off to college on the G.I. Bill and lining up at the marriage bureaus. But when it came to their houses, it was a time of common sense and a belief that less could truly be more. During the Depression and the war, Americans had learned to live with less, and that restraint, in combination with the postwar confidence in the future, made small, efficient housing positively stylish. Economic condition was only a stimulus for the trend toward efficient living. The phrase "less is more" was actually first popularized by a German, the architect Ludwig Mies van der Rohe, who like other people associated with the Bauhaus, a school of design, emigrated to the United States before World War Ⅱ and took up posts at American architecture schools. These designers came to exert enormous influence on the course of American architecture, but none more so than Mies. Mies"s signature phrase means that less decoration, properly organized, has more impact than a lot. Elegance, he believed, did not derive from abundance. Like other modern architects, he employed metal, glass and laminated wood—materials that we take for granted today but that in the 1940s symbolized the future. Mies"s sophisticated presentation masked the fact that the spaces he designed were small and efficient, rather than big and often empty. The apartments in the elegant towers Mies built on Chicago"s Lake Shore Drive, for example, were smaller—two-bedroom units under 1,000 square feet—than those in their older neighbors along the city"s Gold Coast. But they were popular because of their airy glass walls, the views they afforded and the elegance of the buildings" details and proportions, the architectural equivalent of the abstract art so popular at the time. The trend toward "less" was not entirely foreign. In the 1930s Frank Lloyd Wright started building more modest and efficient houses—usually around 1,200 square feet—than the spreading two-story ones he had designed in the 1890s and the early 20th century. The "Case Study Houses" commissioned from talented modern architects by California Arts & Architecture magazine between 1945 and 1962 were yet another homegrown influence on the "less is more" trend. Aesthetic effect came from the landscape, new materials and forthright detailing. In his Case Study House, Ralph Rapson may have mispredicted just how the mechanical revolution would impact everyday life—few American families acquired helicopters, though most eventually got clothes dryers—but his belief that self-sufficiency was both desirable and inevitable was widely shared.

单选题{{B}}Passage 3{{/B}} The Greek's lofty attitude toward scientific research—and the scientists' contempt of utility—was a long time dying. For a millennium after Archimedes, this separation of mechanics from geometry inhibited fundamental technological progress and in some areas repressed it altogether. But there was a still greater obstacle to change until the very end of the middle ages: the organization of society. The social system of fixed class relationships that prevailed through the Middle Ages (and in some areas much longer) itself hampered improvement. Under this system, the laboring masses, in exchange for the bare necessities of life, did all the productive work, while the privileged few—priests, nobles, and kings—concerned themselves only with ownership and maintenance of their own position. In the interest of their privileges they did achieve considerable progress in defense, in warmaking, in government, in trader in the arts of leisure, and in the extraction of labor from their dependents, but they had no familiarity with the process of production. On the other hand, the laborers, who were familiar with manufacturing techniques, had no incentive to improve or increase production to the advantage of their masters. Thus, with one class possessing the requisite knowledge and experience, but lacking incentive and leisure, and the other class lacking the knowledge and experience, there was no means by which technical progress could be achieved. The whole ancient world was built upon this relationship—a relationship as sterile as it was inhuman. The availability of slaves nullified the need for more efficient machinery. In many of the conmonplace fields of human endeavor, actual stagnation prevailed for thousands of years. Not all the glory that was Greece and the grandeur that was Rome could develop the windmill or contrive so simple an instrument as the wheelbarrow—products of the tenth and thirteenth centuries respectively. For about twenty-five centuries, two-thirds of the power of the horse was lost because he wasn't shod, and much of the strength of the ox was wasted because his harness wasn't modified to fit his shoulders. For more than five thousand years, sailors were confined to rivers and coasts by a primitive steering mechanism which required remarkably little alteration (in the thirteenth century) to become a rudder. With any ingenuity at all, the ancient plough could have been put on wheels and the ploughshare shaped to bite and turn the sod instead of merely scratching it—but the ingenuity wasn't forthcoming. And the villager of the Middle Ages, like the men who first had fire, had a smoke hole in the center of the straw and reed thatched roof of his one-room dwelling (which he shared with his animals), while the medieval charcoal burner (like his Stone Age ancestor) made himself a hut of small branches.

单选题Directions: Read the following four texts. Answer the questions below each text by choosing A, B, C, or D. Want a glimpse of the future of health care? Take a look at the way the various networks of people involved in patient care are being connected to one another, and how this new connectivity is being exploited to deliver medicine to the patient-no matter where he or she may be. Online doctors offering advice based on standardized symptoms are the most obvious example. Increasingly, however, remote diagnosis (telemedicine) will be based on real physiological data from the actual patient. A group from the university of Kentucky has shown that by using an off-the shelf (现成的) PDA (personal data assistance) such as a Palm Pilot plus a mobile phone, it is perfectly feasible to transmit a patient's vital signs over the telephone. With this kind of equipment in a first-aid kit (急救包), the cry asking whether there was a doctor in the house could well be a thing of the past. Other medical technology groups are working on applying telemedicine to rural care. And at least one team wants to use telemedicine as a tool for disaster response-especially after earthquakes. Overall, the trend is towards providing global access to medical data and expertise. But there is one problem. Bandwidth is the limiting factor for transmitting complex medical images around the world-CT scans being one of the biggest bandwidth consumers. Communications satellites may be able to cope with the short-term needs during disasters such as earthquakes, wars or famines. But medicine is looking towards both the second-generation internet and third-generation mobile phones for the future of distributed medical intelligence. Doctors have met to discuss computer-based tools for medical diagnosis, training and telemedicine. With the falling price of broadband communications, the new technologies should usher in (迎来) an era when telemedicine and the sharing of medical information, expert opinion and diagnosis are common.

单选题Rubidium, potassium and carbon are three common elements used to date the history of Earth. The rates of radioactive decay of these elements are absolutely regular when averaged out over a period of time; nothing is known to change them. To be useful as clocks, the elements have to be fairly common in natural minerals, unstable but decay slowly over millions of years to form recognizable "daughter" products which are preserved minerals. For example, an atom of radioactive rubidium decays to form an atom of strontium (another element) by converting a neutron in its nucleus to a proton and releasing an electron, generating energy in the process. The radiogenic daughter products of the decay—in this case strontium atoms—diffuse away and are lost above a certain very high temperature. So by measuring the exact proportions of rubidium and strontium atoms that are present in a mineral, researchers can work out how long it has been since the mineral cooled below that critical "blocking" temperature. The main problems with this dating method are the difficulty in finding minerals containing rubidium, the accuracy with which the proportions of rubidium and strontium are measured, and the fact that the method gives only the date when the mineral last cooled below the blocking temperature. Because the blocking temperature is very high, the method is used, mainly for recrystallized (igneous or metamorphic) rocks, not for sediments—rubidium-bearing minerals in sediments simply record the age of cooling of the rocks which were eroded to form the sediments, not the age of deposition of the sediments themselves. Potassium decays to form (a gas) which is sometimes lost from its host mineral by escaping through pores. Although potassium-argon dating is therefore rather unreliable, it can sometimes be useful in dating sedimentary rocks because potassium is common in some minerals which form in sediments at low temperatures. Assuming no argon has escaped, the potassium-argon date records the age of the sediments themselves. Carbon dating is mainly used in archaeology. Most carbon atoms (carbon-12) are stable and do not change over time. However, cosmic radiation bombarding the upper atmospheres is constantly interacting with nitrogen in the atmosphere to create an unstable form of carbon, carbon-14.
