单选题Anthropologists commonly distinguish three forms of marriage: monogamy, the marriage of one man to one woman, polygyny—the marriage of one man to two or more women, and polyandry—the marriage of one woman to two or more men. polygyny and polyandry are often linked under the single term "polygamy", a marriage of one individual to two or more spouses. Though there are many societies which permit, or even encourage, polygamous marriages, it does not follow, in such societies, that every married individual, or even that a majority of them, has more than one spouse. Quite the contrary is true, for in most, if not all, of so called polygamous societies monogamy is statistically the prevailing form. The reason for this is clear: the proportion of male to female births in any human society is roughly the same, and if this proportion is maintained among the sexually mature, a preponderance of plural marriages means that a considerable number of either men or women must remain unmarried. No society can maintain itself under such conditions; the emotional stresses would be too great to be survived. Accordingly, even where the cultural ideals do not prohibit plural marriages, these may occur on any notable scale only societies where for one reason or another, one sex markedly outnumbers the other. In short, monogamy not only prevails in most of the world's societies, either as the only approved form of marriage or as the only feasible form, but it may also prevail within a polygamous society where, very often, only a minority of the population can actually secure more than one spouse. In a polygynous household, the husband must supply a house and garden for each of his wives. The wives live with him in turn, cooking and serving for him during the period of his visit. The first wife takes precedence over the others. Polyandry is much rarer than polygyny. It is often the result of a disproportion in the ratio of men to women. In sum, polygyny is not, as so frequently indicated, universally a result of human immorality. It is simply not true, in this aspect of culture as in many others, that people who follow patterns of culture deemed immoral in our society are thereby lacking in morality. Our ideal and compulsory pattern of marriage, which holds that monogamy is the only appropriate form of marriage, is not shared by all peoples, even by some of those who regularly practice monogamy. In a great many societies, monogamy is only one possible form of marriage, with polygyny or polyandry as perfectly possible, though less frequent, alternatives.

单选题Few insects have inspired as much fear and hatred as the diminutive fire ants, less than half an inch long but living in colonies of more than 250,000 others. Everyone in the southern United States gets to know fire ants sooner or later by painful experience. Fire ants live in large earthen mounds and are true social insects--that means they have a caste system (division of labor), with a specialized caste that lays eggs (queen) and a worker caste of sterile females. There are several reasons that they are considered pests. About 60% of people living in areas where fire ants occur are stung every year. Of these, about 1% have some degree of allergic reaction ( called anaphylaxis ) to the sting. Their large mounds are unsightly and can damage mowing equipment. Fire ants sometimes enter electrical and mechanical equipment and can short out switches or chew through insulation. Finally, as fire ants move into new areas, they reduce diversity of native ants and prey on larger animals such as ground-nesting birds and turtles. Even though fire ants are pests in many circumstances, they can actually be beneficial in others. There is evidence that their predatory activities can reduce the numbers of some other important pests. In cotton, for example, they prey on important pests that eat cotton plants such as bollworms and budworms. In Louisiana sugarcane, an insect called the sugarcane borer used to be a very important pest before fire ants arrived and began preying on it. Fire ants also prey on ticks and fleas. Whether fire ants are considered pest or not depend on where they are found, but one thing is sure--we had best get used to living with them. Eradication attempts in the 1960s and 1970s failed for a number of reasons, and scientists generally agree that complete elimination of fire ants from the United States is not possible. A new, long-term approach to reducing fire ant populations involves classical biological control. When fire ants were accidentally brought to the United States, most of their parasites and diseases were not. Classical biological control involves identifying parasites and diseases specific to fire ants in South America, testing them to be sure that they don't attack or infect native plants or animals, and establishing them in the introduced fire ant population in the United States. Since fire ants are about 5 to 7 times more abundant here than in South America, scientists hope to reduce their numbers using this approach.

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.
