单选题3 Classified Advertising is that advertising which is grouped in certain sections of the paper and is thus distinguished from display advertising. Such groupings as "Help Wanted", "Real Estate", "Lost and Found" are made, the rate charged being less than that for dis play advertising. Classified advertisements are a convenience to the reader and a saving to the advertiser. The reader who is interested in a particular kind of advertisement finds all advertisements of that type grouped for him. The advertiser may, on this account, use a very small advertisement that would be lost if it were placed among larger advertisements in the paper. It is evident that the reader approaches the classified advertisement in a different frame of mind from that in which he approaches the other advertisements in the paper. He turns to a page of classified advertisements to search for the particular advertisement that will meet his needs. As his attention is voluntary, the advertiser does not need to rely to much extent on display type to get the reader's attention. Formerly all classified advertisements were of the same size and did not have display type. With the increase in the number of such advertisements, however, each advertiser within a certain group is vying with others in the same group for the reader's attention. In many cases the result has been an increase in the size of the space used and the addition of headlines and pictures. In that way the classified advertisement has in reality become a dis play advertisement. This is particularly true of real-estate advertising.

单选题The way people hold to the belief that a fun filled, painfree life equals happiness actually reduces their chances of ever attaining real happiness. If fun and pleasure are equal to happiness then pain must be equal to unhappiness. But in fact, the opposite is true: more often than not things that lead to happiness involve some pain. As a result, many people avoid the very attempts that are the source of true happiness. They fear the pain inevitably brought by such things as marriage, raising children, professional achievement, religious commitment, self-improvement. Ask a bachelor why he resists marriage even though he finds dating to be less and less satisfying. If he is honest he will tell you that he is afraid of making a commitment. For commitment is in fact quite painful. The single life is filled with fun, adventure, excitement. Marriage has such moments, but they are not its most distinguishing features. Couples with infant children are lucky to get a whole night"s sleep or a three-day vacation. I don"t know any parent who would choose the word fun to describe raising children. But couples who decide not to have children never know the joys of watching a child grow up or of playing with a grandchild. Understanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations. It liberates time: now we can devote more hours to activities that can genuinely increase our happiness. It liberates money: buying that new car or those fancy clothes that will do nothing to increase our happiness now seems pointless. And it liberates us from envy: We now understand that all those who are always having so much fun actually may not be happy at all.

单选题The Intergovernmental Panel on Climate Change concluded that global warming is no game. They provide evidence that heat-trapping gases related to human activities--such as carbon dioxide from burning coal, oil, and gas--are in part driving global warming by increasing the amount of the sun's heat trapped in the earth's atmosphere. This extra heat is making the global climate system unstable. Because the climate system is complex, scientists cannot predict precisely how much and how fast the climate will change. But sophisticated computer simulations project a range of scenarios for increases in average surface temperature between 1.8° and 6.3°F (1° and 3.5℃) by the year 2100. (Bear in mind that seemingly small changes in temperature can produce major changes in climate. During the last Ice Age, global temperatures were only 5° to 9°F cooler than they are today, but that was sufficient to bury what is now Canada, New York, and New England under a kilometer of ice.) Within the next 20 years, various regions of the world may experience severe changes in climate. Some may be vulnerable to longer droughts, others to more coastal flooding, and many to more frequent bouts of extreme weather. And if global warming continues unchecked, we could well see greater risk to human health as diseases previously found in tropical areas spread to higher latitudes and elevations. Also, insect-borne diseases such as malaria and dengue fever are already moving northward from tropical regions. Forests and wetlands provide critical benefits to human health, by filtering our air and water, and to human welfare, by providing opportunities for recreation and commerce. Changes in regional climate put many such ecosystems at risk by hindering their ability to grow and regenerate. The survival of these wetlands--often are as of high biodiversity that also provide protection against floods--depends on the water's temperature, flow, and level. Scientists are confident that global warming will reduce the area of wetlands and change their distribution. Arctic and subarctic wetlands, which are critical refuge and breeding grounds for large numbers of migratory species, are among the most vulnerable. Other coastal zone habitats--including marshes, mangroves, coral reefs and atolls, and river deltas--will also be threatened. Avoiding these costly damages justifies immediate action to turn off the road to ruin. Scientists and economists have identified many technically feasible, cost-effective opportunities for emissions reductions, including energy-efficiency measures, advanced vehicle technologies, cuts in oil and coal subsidies, and investments in clean, renew-able energy sources like wind and solar power. To take advantage of these opportunities, governments and industry must work together. The Union of Concerned Scientists (UCS) is working to advance policies that will turn our society aside from the ruinous road to a global warming future.

单选题The hotels are full, Japanese tourists throng the designer stores of Waikiki, and the unemployment rate is a mere 3% of the workforce. So what could possibly knock Hawaii, the "aloha" or "welcome" state, off its wave? The answer is that Hawaii's 1.2m residents may one day get fed up with playing host to overseas visitors, 7m of them this year. Indeed, some residents are already fed up. KAHEA, an alliance of environmentalists and defenders of native Hawaiian culture, bemoans the pollution caused by the cruise ships and the risk posed by the tourist hordes to creatures such as the dark-rumped petrel and the Oahu tree snail, or to plants like the Marsilea villosa fern. KAHEA has a point: the US Fish & Wildlife Service currently lists some 317 species, including 273 plants, in the Hawaiian islands as threatened or endangered—the highest number of any state in the nation. Even the state flower, the hibiscus brackenridgei, is on the danger list. The loss of species, says one government report, has been "staggering". As for the impact of tourism on Hawaiian culture, a KAHEA spokeswoman wryly notes the element of exploitation: "Native Hawaiian culture is used as a selling point—come to this paradise where beautiful women are doing the hula on your dinner plate." So what else is new? Hawaii's environment and culture have been under threat ever since Captain Cook and his germ-carrying sailors dropped anchor in 1778. Foreign imports have inevitably had an impact on species that evolved over the millennia in isolation. Moreover, with up to 25 non-native species arriving each year, the impact will continue. But, as the US Geological Survey argues, the impact can add to biodiversity as well as lessen it. The real challenge, therefore, is for Hawaii to find a balance between the costs and the benefits of development in general and tourism in particular. The benefits are not to be sneezed at. The state's unemployment rate has been below the national average for the past two-and-a-half years. Economists at the University of Hawaii reckon that Hawaiians' real personal income rose by 2.8% last year, will rise by 2.7% this year and will continue through 2007 at 2.5%. According to the state's "strategic plan" for the next decade, tourism should take much of the credit, accounting directly and indirectly for some 22% of the state's jobs by 2007, more than 17% of its economic output and around 26% of its tax revenues. The trouble is that the costs can be high, too. As one economist puts it, "We have a Manhattan cost of living and Peoria wage rates." That translates into a median house price today on the island of Oahu, home to three-quarters of the state's population, of $500,000, and a need for many workers to take on more than one job.

单选题The crucial years of the Depression, as they are brought into historical focus, in creasingly emerge as the decisive decade for American art, if not for American culture in general. For it was during this decade that many of the conflicts which had blocked the progress of American art in the past came to a head and sometimes boiled over. Janus-faced, the thirties look backward, sometimes as far as the Renaissance; and at the same time forward, as far as the present and beyond. It was the moment when artists, like Thomas Hart Benton, who wished to turn back the clock to regain the virtues of simpler times came into direct conflict with others, like Stuart Davis and Frank Lloyd Wright, who were ready to come to terms with the Machine Age and to deal with its consequences. America in the thirties was changing rapidly. In many areas the past was giving way to the present, although not without a struggle. A predominantly rural and small town society was being replaced by the giant complexes of the big cities; power was becoming increasingly centralized in the federal government and in large corporations. As a result, traditional American types such as the independent farmer and the small businessman were being replaced by the executive and the bureaucrat. Many Americans, deeply attached to the old way of life, felt disinhereited. At the same time, as immigration decreased and the population became more homogeneous, the need arose in art and literature to commemorate the ethnic and regional differences that were fast disappearing. Thus, paradoxically, the conviction that art, at least, should serve some purpose or carry some message of moral uplift grew stronger as the Puritan ethos lost its contemporary reality. Often this elevating message was a sermon in favor of just those traditional American virtues which were now threatened with obsolescence in a changed social and political context. In this new context, the appeal of the paintings by the Regionalists and the American Scene painters often lay in their ability to recreate an atmosphere that glorified the traditional American values—self-reliance tempered with good-neighborliness, independence modified by a sense of community, hard work rewarded by a sense of order and purpose. Given the actual temper of the times, these themes were strangely anachronistic, just as the rhetoric supporting political isolationism was equally inappropriate in an international situation soon to involve America in a second world war. Such themes gained popularity because they filled a genuine need for a comfortable collective fantasy of a God-fearing, white-picket-fence America, which in retrospect took on the nostalgic appeal of a lost Golden Age. In this light, an autonomous art-for-art's sake was viewed as a foreign invader liable to subvert the native American desire for a purposeful art. Abstract art was assigned the role of the villainous alien; realism was to personify the genuine American means of expression. The argument drew favor in many camps: among the artists, because most were realists; among the politically oriented intellectuals, because abstract art was apolitical; and among museum officials, because they were surfeited with mediocre imitations of European modernism and were convinced that American art must develop its own distinct identity. To help along this road to self-definition, the museums were prepared to set up an artificial double standard, one for American art, and another for European art. In 1934, Ralph Flint wrote in Art News, "We have today in our midst a greater array of what may be called second, third, and fourth-string artists than any other country. Our big annuals are marvelous outpourings of intelligence and skill; they have all the diversity and animation of a fine-ring circus. /
