单选题(1) Gerald Feinberg, the Columbia University physicist, once went so far as to declare that "everything possible will eventually be accomplished." Well, that of course left only the impossible as the one thing remaining for daring intellectual adventurers to whittle away at Feinberg, for one, thought that "they"d succeed even there." (2) It was a point worth considering. How many times in the past had certain things been said to be impossible, only to have it turn out shortly thereafter that the item in question had already been done or soon would be. What greater cliche was there in the history of science than the comic litany of false it-couldn"t-be-dones; the infamous case of Auguste Comte saying in 1844 that it would never be known what the stars were made of, followed in a few years by the spectroscope being applied to starlight to reveal the stars" chemical composition; or the case of Lord Rutherford, the man who discovered the structure of the atom, saying in 1933 mat dreams of controlled nuclear fission were "moonshine." And those weren"t even the worst examples. No, the huffiest of all it-couldn"t-be-done claims centered on the notion that human beings could actually fly, either at all, or across long distances, or to the moon, the stars, or wherever else. (3) There had been so many embarrassments of this type that about mid-century Arthur C. Clarke came out with a guideline for avoiding them, which he termed Clarke"s Law: "When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong." (4) Still, one had to admit there were lots of things left that were really and truly impossible, even if it took some ingenuity in coming up with a proper list of examples. Such as. "A camel cannot pass through the eye of a needle." (Well, unless of course it was a very large needle.) On "It is impossible for a door to be simultaneously open and closed." (Well, unless of course it was a revolving door.) (5) Indeed, watertight examples of the really and truly impossible were so exceptionally hard to come by that paradigm cases turned out to be either trivial or absurd. "I know I will never play the piano like Vladimir Horowitz," offered Milton Rothman, a physicist, "no matter how hard I try". Or, from Scott Lankford, a mountaineer "Everest on roller skates."

单选题{{B}}Directions:{{/B}} There are 5 reading passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C, and D. You should decide on the best choice and mark your answer on the ANSWER SHEET by blackening the corresponding letter in the brackets. No one can be a great thinker who does not realize that as a thinker it is his first duty to follow his intellect to whatever conclusions it may lead. Truth gains more even by the errors of one who, with due study and preparation, thinks for himself, than by the true opinions of those who only hold them because they do not suffer themselves to think. Not that it is solely, or chiefly, to form great thinkers that freedom of thinking is required. On the contrary, it is as much or even more indispensable to enable average human beings to attain the mental stature which they are capable of. There have been, and may again be, great individual thinkers in a general atmosphere of mental slavery. But there never has been, nor ever will be, in that atmosphere an intellectually active people. Where any people has made a temporary approach to such a character, it has been because the dread of heterodox speculation was for a time suspended. Where there is a tacit convention that principles are not to be disputed; where the discussion of the greatest questions which can occupy humanity is considered to be closed, we cannot hope to find that generally high scale of mental activity which has made some periods of history so remarkable. Never when controversy avoided the subjects which are large and important enough to kindle enthusiasm was the mind of a people stirred up from its foundations and the impulse given which raised even persons of the most ordinary intellect to something of the dignity of thinking beings. He who knows only his own side of the case knows little of that. His reasons may be good, and no one may have been able to refute them. But if he is equally unable to refute the reasons on the opposite side; if he does not so much as know what they are, he has no ground for preferring either opinion. The rational position for him would be suspension of judgment, and unless he contents himself with that, he is either led by authority, or adopts, like the generality of the world, the side to which he feels the most inclination. Nor is it enough that he should hear the arguments of adversaries from his own teachers, presented as they state them, and accompanied by what they offer as refutations. That is not the way to do justice to the arguments, or bring them into real contact with his own mind. He must be able to hear them from persons who actually believe them; who defend them in earnest, and do their very utmost for them. He must know them in their most plausible and persuasive form: he must feel the whole force of the difficulty which the true view of the subject has to encounter and dispose of; else he will never really possess himself of the portion of truth which meets and removes that difficulty. Ninety-nine in a hundred of what are called educated men are in this condition; even of those who can argue fluently for their opinions. Their conclusion may be true, but it might be false for anything they know: they have never thrown themselves into the mental position of those who think differently from them and considered what such persons may have to say; and consequently they do not, in any proper sense of the word, know the doctrines which they themselves profess. They do not know those parts of it which explain and justify the remainder; the considerations which show that a fact which seemingly conflicts with another is reconcilable with it, or that, of two apparently strong reasons, one and not the other ought to be preferred.

单选题Exceptional children are different in some significant way from others of the same age. For these children to develop to their full adult potential, their education must be adapted to those differences. Although we focus on the needs of exceptional children, we find ourselves describing their environment as well. While the leading actor on the stage captures our attention, we are aware of the importance of the supporting players and the scenery of the play itself. Both the family and the society in which exceptional children live are often the key to their growth and development. And it is in the public schools that we find the full expression of society" s understanding—the knowledge, hopes, and fears that are passed on to the next generation. Education in any society is a mirror of that society. In that minor we can see the strengths, the weaknesses, the hopes, the prejudices, and the central values of the culture itself. The great interest in exceptional children shown in public education over the past three decades indicates the strong feeling in our society that all citizens, whatever their special conditions, deserve the opportunity to fully develop their capabilities. "All men are created equal." We"ve heard it many times, but it still has important meaning for education in a democratic society. Although the phrase was used by this country"s founders to denote equality before the law, it has also been interpreted to mean equality of opportunity. That concept implies educational opportunity for all children—the right of each child to receive help in learning to the limits of his or her capacity, whether that capacity be small or great. Recent court decisions have confirmed the right of all children—disabled or not—to an appropriate education, and have ordered that public schools take the necessary steps to provide that education. In response, schools are modifying their programs, adapting instruction to children who are exceptional, to those who cannot profit substantially from regular programs.

单选题Cities develop as a result of functions that they can perform, some functions result directly from the ingenuity of the citizenry, but most functions result from the needs of the local area and of the surrounding hinterland (the region that supplies goods to the city and to which the city furnishes services and other goods). Geographers often make a distinction between the situation and the site of a city. Situation refers to the general position in relation to the surrounding region, whereas site involves physical characteristics of the specific location. Situation is normally much more important to the continuing prosperity of a city. If a city is well situated in regard to its hinterland, its development is much more likely to continue. Chicago, for example, possesses an almost unparalleled situation: it is located at the southern end of a huge lake that forces eastwest transportation lines to be compressed into its vicinity, and at a meeting of significant land and water transport routes. It also overlooks what is one of the world's finest large farming regions. These factors ensured that Chicago would become a great city regardless of the disadvantageous characteristics of the available site, such as being prone to flooding during thunderstorm activity. Similarly, it can be argued that much of New York City's importance stems from its early and continuing advantage of situation. Philadelphia and Boston both originated at about the same time as New York and shared New York's location at the western end of one of the world's most important oceanic trade routes, but only New York possesses an easyaccess functional connection (the HudsonMohawk lowland ) to the vast Midwestern hinterland. This account does not alone explain New York's primacy, but it does include several important factors. Among the many aspects of situation that help to explain why some cities grow and others do not, original location on a navigable waterway seems particularly applicable. Of course, such characteristic as slope, drainage, power resources, river crossings, coastal shapes, and other physical characteristics help to determine city location, but such factors are normally more significant in early stages of city development than later.

单选题During the past generation, the American middle-class family that once could count on hard work and fair play to keep itself financially secure had been transformed by economic risk and new realties. Now a pink slip, a bad diagnosis, or a disappearing spouse can reduce a family from solidly middle class to newly poor in a few months. In just one generation, millions of mothers have gone to work, transforming basic family economics. Scholars, policymakers, and critics of all stripes have debated the social implications of these changes, but few have looked at the side effect; family risk has risen as well. Today's families have budgeted to the limits of theirs new two-paycheck status. As a result, they have lost the parachuted they once had in times of financial setback—a back-up earner(usually Mom)who could go into the workforce if the primary earner got laid off or fell sick. This " added-worker effect" could support the safety net offered by unemployment insurance or disability insurance to help families weather bad times. But today, a disruption to family fortunes can no longer be made up with extra income from an otherwise stay at home partner. During the same period, families have been asked to absorb much more risk in their retirement income. Steelworkers, airline employees, and now those in the auto industry are joining millions of families who must worry about interest rates, stock market fluctuation, and the harsh reality that they may outlive their retirement money. For much of the past year, President Bush campaigned to move Social Security to a saving-account model, with retirees trading much or all of their guaranteed payments for payments depending on investment returns. For younger families the picture is not any better. Both the absolute cost of healthcare and the share of it borne by families have risen—and newly fashionable health-saving plans are spreading from legislative halls to Wal-Mart workers, with much higher deductibles and a large new dose of investment risk for families' future healthcare. Even demographics are working against the middle class family, as the odds of having a weak elderly parent—and all the attendant need for physical and financial assistance—have jumped eightfold in just one generation. From the middle-class family perspective, much of this, understandably, looks far less like an opportunity to exercise more financial responsibility, and a good deal more like a frightening acceleration of the wholesale shift of financial risk onto their already overburdened shoulders. The financial fallout has begun, and the political fallout may not be far behind.

单选题In a sense, the new protectionism is not protectionism at all, at least not in the traditional sense of the term．The old protectionism referred only to trade restricting and trade expanding devices, such as the tariff or export subsidy．The new protectionism is much broader than this； it includes interventions into foreign trade but is not limited to them．The new protectionism, in fact, refers to how the whole of government intervention into the private economy affects international trade．The emphasis on trade is still there, thus came me term"protection"．But what is new is the realization that virtually all government activities can affect international economic relations． The emergence of the new protectionism in the Western world reflects the victory of the interventionist．or welfare economy over the market economy．Jab Tumiler writes, "The old protectionism…coexisted, without any apparent intellectual difficulty with the acceptance of the market as a national as well as an international economic distribution mechanism．Indeed, protectionists as well as(if not more than)free traders stood for laissez faire．Now, as in the 1930s, protectionism is an expression of a profound skepticism as to the ability of the market to distribute resources and incomes to societies sarisfaction．" It is precisely this profound skepticism of the market economy that is responsible for the protectionism．In a market economy,economic change of various colors implies redistribution of resources and incomes．The same opinion in many communities apparently is that such redistributions often are not proper．Therefore, the government intervenes to bring about a more desired result． The victory of the welfare state is almost complete in northem Europe．In Sweden, Norway, Finland, Denmark, and the Netherlands, government intervention in almost all aspects of economic and social life is considered normal．In Great Britain this is only somewhat less true．Government traditionally has played a very active role in economic life in France and continued to do so．Only West Germany dares to go against the tide towards excessive interventionism in Western Europe．It also happens to be the most successful Western European economy． The welfare state has made significant progress in the United States as well as in Western Europe．Social security,unemployment insurance, minimum wage laws, and rent control are by now traditional welfare state elements on the American scene．

单选题The world"s greatest snow-capped peaks, which run in a chain from the Himalayas to Tian Shah 1 the border of China and Kyrgyzstan, have lost no ice 2 the last decade, new research shows. The discovery has stunned scientists, who 3 that around 50bn tons of meltwater 4 each year and not being replaced by new snowfall. The study is the first to survey all the world"s icecaps and glaciers and was made 5 by the use of satellite data. Overall, the contribution of melting ice outside the two largest caps— Greenland and Antarctica—is much 6 than previously estimated, with the lack of ice loss in the Himalayas and the other high peaks of Asia 7 most of the discrepancy. Bristol University glaciologist Prof Jonathan Bamber, who was not part of the research team, said, "The very unexpected result was the negligible mass loss from high mountain Asia which is not 8 different from zero. " The melting of Himalayan glaciers caused 9 in 2009 when a report from the UN"s Intergovernmental Panel on Climate Change mistakenly stated that they would disappear by 2035, instead of 2350. 10 , the scientist who led the new work is clear that while greater uncertainty has been discovered in Asia"s highest mountains, the melting of ice caps and glaciers around the world 11 a serious concern. "Our results and those of everyone else show we are losing a huge amount of water into the oceans every year," said Prof John Wahr of the University of Colorado. "People should be just as worried about the melting of the world"s ice as they were before. " His team"s study, published in the journal Nature, concludes that between 443-629bn tons of meltwater overall are added to the world"s oceans each year. This is 12 sea level by about 1.5mm a year, the team reports, 13 the 2mm a year caused by expansion of the warming ocean. The scientists are careful to point out that lower-altitude glaciers in the Asian mountain ranges—sometimes dubbed the "third pole" —are 14 melting. Satellite images and reports confirm this. But over the study period, enough ice was added to the peaks to 15 .
