填空题A. Key disease carriers, such as insects and rats, thrive in crowded urban settings, further facilitating spread. B. The unprecedented population densities in fourteenth-century Europe, for example, led to the plague outbreak that claimed the lives of one fourth of the population. C. Although these infections are easily preventable if adequate water and sanitation are available, the vast majority of the world's population are lifelong victims. D. While new global markets have created unprecedented economic opportunities and growth, the health risks of our increasingly interconnected and fast-paced world continue to grow. E. Pathogens can more readily establish in large populations, since all infectious diseases require a critical number of vulnerable individuals in order to take root and spread. F. These areas can serve as a perpetual reservoir of disease or disease vectors, placing other parts of the city at risk of an outbreak and allowing the disease to continue evolving, often into a deadlier strain. Historically, the spread, prevalence, and very existence of contagious disease have wholly depended on the growth and concentration of human populations. (66) And though the last century has witnessed substantial worldwide success in combating many past scourges—such as polio and smallpox—infectious diseases still claim more lives than any other group of diseases. The prevailing demographic trends continue to create a crowded human "medium" that both invites and is vulnerable to infection. The share of humanity living in cities with more than 1 million people has surged from less than 5 percent in 1900 to nearly 40 percent today, creating the ideal setting for the resurgence of old infectious diseases as well as the development of new ones. (67) Overcrowding—the increased proximity of susceptible individuals—is a principal risk factor for the incidence and spread of all major infectious diseases, including tuberculosis, dengue fever, malaria, and acute respiratory illnesses, which are unable to spread and survive in low population densities. (68) Aside from sheer growth and increasing density, the urbanization under way in developing nations is often accompanied by deteriorating health indicators and increased exposure to disease risk factors. Access to clean water, good hygiene, and adequate housing are sorely lacking in developing nations. As a result, waterborne infections such as cholera and other diarrheal diseases account for 90 percent of all infectious diseases in developing countries—and 40 percent of all deaths in some nations. (69) In both industrial and developing nations, the incidences of a wide range of infectious diseases, including tuberculosis, diarrheal diseases, and HIV/AIDS, are considerably higher in urban slums—where poverty and compromised health define the way of life—than in the rest of the city.

填空题In 2004 and again in 2006, women told pollsters that the concerns that motivated them to decide whether and for whom to vote were centered on nontraditional "Women"s issues". Women are not single-issue voters, either. 1 . In reality, women"s voting patterns indicate quite the opposite. Women are not monolithic in their attitudes about, or votes within, the political system. 2 . In the end, women voters ask themselves two core questions when deciding whom to support for president: "Do I like that person?" and "Is that person like me?" The first question is the classic "living room" test. The second is a more complex inquiry that probes whether women believe a candidate cars about, values, confronts, and feats he same things they do. Party loyalty trumps gender, as indicated by a July 2007 Newsweek survey, which found that 88 percent of men and 85 percent of women say that if their party nominated a woman candidate that they would vote for her if she were qualified for the job. 3 : Only 60 percent of men and 56 percent of women believe that the country is ready for a woman president. With regard to race, voters are less hesitant to vote for a qualified African-American candidate of their party, as 92 percent of whites and 93 percent of nonwhites say that they would endorse such a candidate. 4 : Only 59 percent of white voters and 58 percent of nonwhite voters believe that the country would elect a black president. Whereas the contest for president is the most wide-open in decades, one thing is certain: 5 . A. The media"s focus on the contentious ones makes it seem as if women only care about one issue on Election Day and that it takes special attention to that issue to compel women to vote B. Traditionally, women are thought to gravitate more toward the "SHE" cluster of issues, Social Security, health care, and education, while men are considered more interested in the "WE" issues, war and the economy C. Like gender, fewer voters doubt that the country is ready for an African-American president D. Americans express less enthusiasm, however, about the "female factor", when it comes to how they judge their fellow citizens E. Women, as they have since 1980, will be a majority of the electorate that decides who next occupies the Oval Office F. When it comes to voting, one woman might vote for all Democrats, another might vote straight-ticket Republican, while a third might take the salad-bar approach to decide her vote

填空题(51)"Humanism" has used to mean too many thing to be a very satisfactory term. (52) Nevertheless, and in the lack of a better word, (53) I shall use it here to explain for the complex of attitudes which this discussion has undertaken to defend. (54) In this sense a humanist is anyone who rejects the attempt to describe or account of man wholly on the basis of physics, chemistry, and animal behavior. (55) He is anyone who believes that will, reason, and purpose are real and significant: that value and justice are aspects of a reality called good and evil and rests upon some foundation other than custom; (56) that consciousness is so far from a mere epiphenomenon that it is the most tremendous of actualities. (57) that the unmeasure, may be significant; or to sum it all up; (58) that those human realities which sometimes seem to exist only in human mind are the perceptions of the mind. (59) He is, in other words, anyone who says that there are more things in heaven and earth than those dreamed of in the positivist philosophy. (60) Originally, to be sure, the term humanist meant simply anyone who thonght the study of ancient literature his chief concern. Obviously it means, as I use it, very much more. (61) But there remains nevertheless a certain connection between the aboriginal meaning and that I am attempting to give it, (62) because those whom I describe as humanists usually recognize that literature and the arts have been pretty consistently "on its side" and (63)because it is often to literature that they turn to renew their faith in the whole class of truths which the modem world has so consistently tended, to dismiss as the mere figments of a wishful thinking imagination. (64) Insofar as this modern world gives less and less attention to its literary past, insofar as it dismisses that past as something outgrow and (65) to be discarded as much as the imperfect technology contemporary with it has been discarded, (66) just to that extent it facilitate the surrender of humanism to technology. (67) The literature is to be found, directly expressed or (68) more often, indirectly implied, the most effective correction to the views now most prevalent among the thinking and unthinking. (69) The great imaginative writers present a picture of human nature and of human life which carries conviction and thus giving the lie to all attempts to reduce man to a mechanism. Novels and poems, and dramas are so persistently concerned with the values which relativism rejects that one might even define literature as the attempt to pass value judgments upon representations of human life, (70) More often than not those of its imaginative persons who fail to achieve power and wealth are more successful than those who do not--by standards which the imaginative writer persuades us to accept as valid.
