单选题The single business of Henry Thoreau, during forty odd years of eager activity, was to discover an economy calculated to provide a satisfying life. His one concern, which gave to his ramblings in Concord fields a value of high adventure, was to explore the true meaning of wealth. As he understood the problems of economics, there were three possible solutions open to him, to exploit himself, to exploit his fellows, or to reduce the problem to its lowest denominator. The first was quite impossible——to imprison oneself in a treadmill when the morning called to great adventure. To exploit one's fellows seemed to Thoreau's sensitive social conscience an even greater infidelity. Freedom with abstinence seemed to him better than serfdom with material well-being, and he was content to move to Walden Pond and set about the high business of living, "to front only the essential facts of life and to see what it had to teach." He did not advocate that other men should build cabins and live isolated. He had no wish to dogmatize concernig the best mode of living——each must settle that for himself. But that a satisfying life should be lived, he was virtually concerned. The story of his emancipation from the lower economics is the one romance of his life, and Walden is his great book. It is a book in praise of life rather than of Nature, a record of calculating economies that studied saving in order to spend more largely. But it is a book of social criticism as well, in spite of its explicit denial of such a purpose. In considering the true nature of economy he concluded, with Ruskin, that the cost of a thing is the amount of life which is required in exchange for it, immediatey or in the long run. In Walden Thoreau elaborated the text: "The only wealth is life.\

单选题{{B}}Passage Five{{/B}} Nanotechnology, according to its fans, will jump-start a new industrial revolution with molecular-sized structures as complex as the human cell and 100 times stronger than steel. The new technology transforms everyday products and the way they are made by manipulating atoms so that materials can be shrunk, strengthened and lightened all at once. To date only modest nanotech-based products--such as stain-resistant fabrics and fresh food packaging--have entered the market, but some scientists predict nanotechnology will eventually be the only game in town. "It will be a ubiquitous technology," said George Stephanopoulos, professor of chemical engineering at the Massachusetts Institute of Technology. He echoes other nanotech supporters who say industrial countries are already sliding toward its use in every aspect of manufacturing. Aided by recent advances in microscopes, scientists can now place single atoms where they want for the first time. The potential applications are numerous, with microscopic computers, cancer-killing antennae and nonpolluting car engines on the distant horizon. When it's all going to happen, though, is another matter. According to most scientific accounts, the nanotech future may be 10 to 20 years off. Major hurdles need to be jumped. First, there is a lack of economic mass production. Some of the more complicated devices would require exact placement of billions of atoms. "It may take the lifetime of the universe to complete the construction of (such a)device, " said George Barbastathis, assistant professor at NIT. Another challenge is bridging the nanoscale and macroscopic, he said. In other words, the smallness of a nano device is useless when it must be attached to large wires. It's unclear how scientists will overcome these problems. And fears derived from science fiction threaten to derail nano-technology even as it emerges, in much the same way popular anxiety over "super-weeds" and "frankenfoods" have hobbled biotechnology in agriculture and fear of "designer babies" has set back stem-cell research. Lured by a market with billions of dollars in potential profits, giants like GE, Intel, Motorola and IBM are already heavily involved in research. Worldwide, the two, industries with the potential to win big with nanotechnology are electronics and biotechnology, according to MIT researchers. On the biotech front, scientists are promoting the notion of nanoparticles made from gold that could be triggered remotely to heat and kill individual cancer cells. Nanotechnology holds equal promise for wealth creation, but there isn't a consensus among venture capitalists on how to realize it. "Which direction is it going to work out in? That's the question on everyone's mind," Gang Chen, an associate professor at the MIT, told scientists at a Boston nano gathering.

单选题Cosmopolitanism is concerned to disclose the ethical, cultural, and legal basis of political order in a world where political communities and states matter, but not only and exclusively. In circumstances where the trajectories of each and every country are tightly entwined, the partiality, one-sidedness and limitedness of "reasons of state" need to be recognized. While states are hugely important vehicles to aid the delivery of effective regulation, equal liberty, and social justice, they should not be thought of as ontologically privileged. Two accounts of cosmopolitanism bear on its contemporary meaning. The first was set out by the Stoics, who were the first to refer explicitly to themselves as cosmopolitans, seeking to replace the central role of the polis in ancient political thought with that of the cosmos in which humankind might live together in harmony(Horstmann, 1976). The Stoics developed this thought by emphasizing that we inhabit two worlds — one which is local and assigned to us by birth and another which is "truly great and truly common"(Seneca). Each person lives in a local community and in a wider community of human ideals, aspirations, and argument. The basis of the latter lies in what is fundamental to all—the equal worth of reason and humanity in every person. Allegiance is owed, first and foremost, to the moral realm of all humanity, not to the contingent groupings of nation. The second conception of cosmopolitanism was introduced in the eighteenth century when the term Weltburger(world citizen)became one of the key terms of the Enlightenment. The most important contribution to this body of thought can be found in Kant's writings. Kant linked the idea of cosmopolitanism to an innovative conception of "the public use of reason," and explored the ways in which this conception of reason can generate a critical vantage point from which to scrutinize civil society. It is important to stress that cosmopolitan philosophy does not deny the reality and ethical relevance of living in a world of diverse values and identities. It does not assume that unanimity is attainable on all practical -political questions. The elaboration of cosmopolitan principles is not an exercise in seeking a general and universal understanding on a wide spectrum of issues concerning the broad conditions of life or diverse ethical matters(for example, abortion, animal rights, or the role of voluntary euthanasia). This is not how a modern cosmopolitan project should be understood. Rather, at stake is a more restrictive exercise aimed at reflecting on the moral status of persons, the conditions of agency, and collective decision-making. It is important to emphasize that this exercise is constructed on the assumption that ground rules for communication, dialogue, and dispute settlement are not only desirable but essential precisely because all people are of equal moral value and their views on a wide of moral-political questions will conflict. The principles of cosmopolitanism are the conditions of taking cultural diversity seriously and of building a democratic culture to mediate clashes of the cultural good. They are, in short, about the conditions of just difference and democratic dialogue. The aim of modern cosmopolitanism is the conceptualization and generation of the necessary background conditions for a "common" or "basic" structure of individual action and social activity.

单选题It was a normal day in the life of the American Red Cross in Greater New York. First, part of a building on West 140th Street, in Harlem, fell down. Beds tumbled through the air, people slid out of their apartments and onto the ground, three people died, and the Red Cross was there, helping shocked residents find temporary shelter, and food and clothing. Then it was back downtown for that evening's big fund-raiser, the Eleventh Annual Red Cross Award Dinner Dance, at the Pierre. "That's why I have bad hair tonight," said Christopher Peake, a Red Cross spokesman who had spent much of the day at the Harlem scene, in the drizzling rain. He was now in a tuxedo, and actually his hair didn't look so bad, framed by a centerpiece of tulips and jonquils, and perhaps improved by subdued lighting from eight crystal chandeliers. Definitely not having a had-hair night was Elizabeth Dole, the wife of Senator Robert Dole and the president of the American Red Cross. President Dole has chestnut-colored Republican hair, which was softly coifed, and she was wearing a fitted burgundy velvet evening suit ("Someone made it for me! I love velveti" she exclaimed, in her enthusiastic, Northern Carolina hostess voice) and sparkling drop earrings. Of course, she hadn't been standing in the rain in Harlem; she had just flown up on the three-o'clock shuttle from Washington. Dole is extremely pretty, with round green eyes and a full mouth and a direct personality. She tilts her head attentively when she listens. She was the recipient of the evening's award; previous award winners have included Alice Tully, Princess Yasmin Asa Khan, .. and, most recently, Brooke Astor. Not exactly a sequence at the end of which you would expect to find Elizabeth Dole, but award givers are famous for having political instincts as well as philanthropic ones. Surrounded by the deep-blue swags and golden draperies of the ballroom were more than thirty-five dinner tables set with groupings of candles and floral centerpieces and Royal Doulton china. American Express was there. So were Bristol-Myers Squibb; Coopers the New York Times Company; Union Bank of Switzerland; Chemical Bank; New York Life; ... and Price Waterhouse. The actress Arlene Dahl, with her rather red hair and her bearded husband, presided over one table. Otherwise, it was a typical, faceless, captain-of-industry fund raiser (no models! no stars! ), of which there seems to be at least one every night in New York City. It was not a society night, but still the evening raised four hundred and thirty thousand dollars.
