单选题"Popular art" has a number of meanings, impossible to define with any precision, which range from folklore to junk. The poles are clear enough, but the middle tends to blur. The Hollywood Western of the 1930's for example, has elements of folklore, but is closer to junk than to high art or folk art. There can be great trash, just as there is bad high art. The musicals of George Gershwin are great popular art, never aspiring to high art. Schubert and Brahms, however, used elements of popular music--folk themes--in works clearly intended as high art. The case of Verdi is a different one: he took a popular genre-bourgeois melodrama set to music (an accurate definition of nineteenth-century opera) and, without altering its fundamental nature, transmuted it into high art. This remains one of the greatest achievements in music, and one that cannot be fully appreciated without recognizing the essential trashiness of the genre. As an example of such a transmutation, consider what Verdi made of the typical political elements of nineteenth-century opera. Generally in the plots of these operas, a hero or heroine--usually portrayed only as an individual, unfettered by class--is caught between the immoral corruption of the aristocracy and the doctrinaire rigidity or secret greed of the leaders of the proletariat. Verdi transforms this naive and unlikely formulation with music of extraordinary energy and rhythmic vitality, music more subtle than it seems at first hearing. There are scenes and arias that still sound like calls to arms and were clearly understood as such when they were first performed. Such pieces lend an immediacy to the otherwise veiled political message of these operas and call up feelings beyond those of the opera itself. Or consider Verdi's treatment of character. Before Verdi, there were rarely any characters at all in musical drama, only a series of situations which allowed the singers to express a series of emotional states. Any attempt to find coherent psychological portrayal in these operas is misplaced ingenuity. The only coherence was the singer's vocal technique: when the cast changed, new arias were almost always substituted, generally adapted from other operas. Verdi's characters, on the other hand, have genuine consistency and integrity. Even if, in many casals, the consistency is that of pasteboard melodrama, the integrity of the character is achieved through the music: once he had become established. Verdi did not rewrite his music for differenf singers or countenance alterations or substitutions of somebody else's arias in one of his operas, as every eighteenth-century composer had done. When he revised an opera, it was only for dramatic economy and effectiveness.

单选题{{B}}Text 4{{/B}} Companies have embarked on what looks like the beginnings of a re-run of the mergers and acquisitions (M&A) wave that defined the second bubbly half of the 1990s. That period, readers might recall, was characterized by a collective splurge that saw the creation of some of the most indebted companies in history, many of which later went bankrupt or were themselves broken up. Wild bidding for telecoms, internet and media assets, not to mention the madness that was Daimler's $40 billion motoring takeover in 1998-1999 of Chrysler or the Time-Warner/AOL mega-merger in 2000, helped to give mergers a thoroughly bad name. A consensus emerged that M&A was a great way for investment banks to reap rich fees, and a sure way for ambitious managers to betray investors by trashing the value of their shares. Now M&A is back. Its return is a global phenomenon, but it is perhaps most striking in Europe, where so far this year there has been a stream of deals worth more than $600 billion in total, around 40% higher than in the same period of 2004. The latest effort came this week when France's Saint-Gobain, a building-materials firm, unveiled the details of its￡3.6 billion ($6.5 billion) hostile bid for BPB, a British rival. In the first half of the year, cross-border activity was up threefold over the same period last year. Even France Telecom, which was left almost bankrupt at the end of the last merger wave, recently bought Amena , a Spanish mobile operator. Shareholder's approval of all these deals raises an interesting question for companies everywhere, are investors right to think that these mergers are more likely to succeed than earlier ones? There are two answers. The first is that past mergers may have been judged too harshly. The second is that the present rash of European deals does look more rational, but-and the caveat is crucial-only so far. The pattern may not hold. M&A 's poor reputation stems not only from the string of spectacular failures in the 1990s, but also from studies that showed value destruction for acquiring shareholders in 80% of deals. But more recent studies by economists have introduced a note of caution. Investors should look at the number of deals that succeed or fail (typically measured by the impact on the share price), rather than (as you might think) weighing them by size. For example, no one doubts that the Daimler-Chrysler merger destroyed value. The combined market value of the two firms is still below that of Daimler alone before the deal. This single deal accounted for half of all German M&A activity by value in 1998 and 1999, and probably dominated people's thinking about mergers to the same degree. Throw in a few other such monsters and it is no wonder that broad studies have tended to find that mergers are a bad idea. The true picture is more complicated.

单选题The evolution of the social sciences has reached a crucial point that might be called a phase change in which old, atomistic, and impressionistic ways of doing research are superseded by a far more systematic and united methodology. To bring social science to the level of rigor already achieved by some of the physical sciences, a new type Of facility will be needed. This will be a transdisciplinary, Internet-based collaborative endeavour that will provide social and behavioral scientists with the databases, software and hardware tools, and other resources to conduct worldwide research that integrates experimental, survey, geographic, and economic methodologies on a much larger scale than was possible previously. This facility will enable advanced research and professional education in economics, sociology, psychology, political science, social geography, and related fields. In many branches of social science, a new emphasis on the rigor of formal laboratory experimentation has driven researchers to develop procedure and software to conduct online interaction experiment using computer terminals attached to local area networks. The opportunity to open these laboratories to the Internet will reduce the cost per research participant and increase greatly the number of institutions, researchers, students, and research participants who can take part. The scale of social science experimentation can increase by an order of magnitude or more, examining a much wider range of phenomena and ensuring great confidence in results through multiple replication of crucial studies. Technology for administering questionnaires to very large numbers of respondents over the Internet will revolutionize survey research. Data from past questionnaire surveys can be the springboard for new surveys with vastly larger numbers of respondents at lower cost than by traditional methods. Integrated research studies can combine modules using both questionnaire and experimental methods. Results can be linked via geographic analysis to other sources of data including census information, economic statistics, and data from other experiments and surveys. Longitudinal studies will conduct time-series comparisons across data sets to chart social and economic trends. Each new study will be designed so that the data automatically and instantly become part of the archives, and scientific publications will be linked to the data sets on which they are based so that the network becomes a universal knowledge system.

单选题{{B}}Text 4{{/B}} Eco-tourism—travel that preserves the environment and promotes the welfare of local people— continues to gain force. Impressed by the success of countries like Costa Rica and Ecuador, which have lured flocks of travelers for mountain treks and jungle safaris, a growing number of regions across tile globe are turning to eco-tourism as a strategy' for economic growth. Omar Bongo, the president of Gabon, a developing country in west central Africa, bas set aside about 10 percent of the country's landmass for 13 national parks. Green Visions, a tourism and environment protection company, based in Sarajevo. Bosnia-Herzegovina, is pioneering an eco-tourism development plan in Central Europe with "green adventures" that promote environmental principles and support local businesses. Even Greece, better known for its pumping night life and archaeological monuments, devotes a section of its national tourism' Web site to "Greek nature" and eco-tourism. Over the last four years, at least 48 countries, from Puerto Rico to Portugal, have created or started to define a national strategy for eco-tourism development, according to a 2004 eco-tourism report by Mintel International Group, a market-research company based in Britain. Though eco-tourism has long conjured images of biodiversity hot spots in countries like Belize, parts of the United States are starting to embrace the trend too. For example, the Wisconsin Department of Tourism will begin testing a new certification program in March called Travel Green Wisconsin. Designed to encourage hotels and tour operators to reduce their environmental impact, the program is aimed at protecting the natural areas that play a significant role in defining the state as a tourist destination. If. successful, the program will be rolled out statewide next year. For businesses, eco-friendly initiatives not only offer marketing advantages but can help with the bottom line. Hotels can cut costs by doing everything from installing energy-saving light bulbs to asking travelers to reuse their towels. And some 58.5 million U.S. travelers, or 38 percent, would pay more to use travel companies that strive to protect and preserve the environment, according to a study by the Travel Industry Association of America sponsored by National Geographic Traveler. Of those travelers. 61 percent said they would pay 5 to 10 percent more to use such companies. However. selecting among the growing number of eco-friendly choices can be frightening, especially given the ever-broadening category, which now encompasses everything from basic campsites to high-end mountain lodges, lama trekking to motorcycle tours through the jungle. Enter the Sustainable Tourism Certification Network of the Americas—a partnership of certification programs, environmental groups, government organizations and others, led by the Rainforest. Alliance and the International Ecotourism Society—which aims to promote sustainability and higher environmental and social standards for tourism. In September, the network designed a series of baseline criteria for certification to help generate credibility among members and promote local conservation. This year, the document will be put up for public consultation before being fully ratified. "Certification is a way for us to avoid green washing," the practice of promoting something as ecotourism while behaving in an environmentally irresponsible way, said Ronald Sanabria. director of sustainable tourism at the Rainforest Alliance. "Certification for us is a tool to avoid that and to ensure third-party assessments of requirements and really prove the company."
