单选题. ①Jane Austen's relationship to Romanticism has long been a vexed one. ②Although her dates (1775-1817) place her squarely within the period, she traditionally has been studied apart from the male poets whose work defined British Romanticism for most of the twentieth century. ③In the past her novels were thought to follow an Augustan mode at odds with the Romantic ethos. ④Even with the advent of historicist and feminist criticism, which challenged many previous characterizations of Austen as detached from the major social, political and aesthetic currents of her time, she continued to be distinguished from her male contemporaries. ⑤Jerome McCann, for example, insists that Austen does not espouse the Romantic ideology. ⑥Anne Mellor declares that Austen, along with other "leading women intellectual and writers of the day" "did not", participate in the Romantic "spirit of the age" but instead embraced an alternative ideology that Mellor labels "feminine Romanticism". ①To be sure, some critics throughout the years have argued for Austen's affinities with one or more of the male Romantic poets. ②A special issue of the Wordsworth Circle (Autumn 1976)was devoted to exploring connections between Austen and her male contemporaries. ③Clifford Siskin in his historicist study of Romanticism argued that Austen does participate in the same major innovation, the naturalization of belief in a developing self, as that characterized in Wordsworth's poetry and other key works from the period. ④Recently, three books have appeared (by Clara Tuite, William Galperin, and William Deresiewicz) that in various ways treat Austen as a Romantic writer and together signal a shift in the tendency to segregate the major novelist of the age from the major poets. ①The present essay seeks to contribute to this goal of firmly integrating Austen within the Romantic movement and canon. ②It does so by pointing out affinities between Austen and a writer with whom she has not commonly been associated, John Keats. ③Most comparisons of Austen and the Romantic poets have focused on Wordsworth and Byron, whose works we know she read. ④Although Austen could not have read Keats's poems, which only began to appear in print during the last years of her life, and there is no evidence that Keats knew Austen's novels, a number of important similarities can be noted in these writers' works that provide further evidence to link Austen with the Romantic movement, especially the period of second-generation Romanticism when all of her novels were published.1. The primary purpose of the passage is to ______

单选题. ①Biologists have long debated about whether egg production in birds is biologically highly costly, some theorizing that egg production is energetically or nutritionally demanding. ②Lack, however, suggested that clutch size—the number of eggs a bird lays per breeding cycle—is far below the potential limit of egg production. ③He suggested that clutch size had instead evolved in relation to the number of young that the parents could successfully rear. ④Subsequently, most studies focused on limitations operating during chick rearing, particularly among altricial species (species in which the parents feed their young in the nest). ⑤Lack later recognized that in precocial species (species in which young feed themselves), clutch size might be explained by different factors—the availability of food for egg-laying females, for example.48. The passage suggests that biologists who say egg production in birds is biologically highly costly would agree that clutch size is determined primarily by ______

单选题. ①The finding that there were rock-melting temperatures on asteroids for sustained periods is puzzling: asteroids' heat source is unknown, and unlike planet-sized bodies, such small bodies quickly dissipate heat. ②Rubin suggests that asteroids' heat could have derived from collisions between asteroids. ③Skeptics have argued that a single impact would raise an asteroid's overall temperature very little and that asteroids would cool too quickly between impacts to accumulate much heat. ④However, these objections assumed that asteroids are dense, solid bodies. ⑤A recent discovery that asteroids are highly porous makes Rubin's hypothesis more plausible. ⑥When solid bodies collide, much debris is ejected, dissipating energy. ⑦Impacts on porous bodies generate less debris, so more energy goes into producing heat. ⑧Heat could be retained as debris fall back into impact craters, creating an insulating blanket.17. The passage suggests that one factor that has made it difficult to account for the temperatures once reached by asteroids is ______

单选题16. The immune systems of hamsters injected with laboratory cultures of Borrelia burgdorferi, the bacterium that causes Lyme disease, respond differently than do the immune systems of people infected with the bacterium as a result of the bites of ticks, the disease's carrier. However, when hamsters are infected with the bacterium by tick bites, their immune-system response is identical to the human one. Probably, therefore, the bacterium in the ticks has a different form from the bacterium cultured in the laboratory. The argument in the passage assumes which of the following? ______

单选题. ①The most dramatic changes that took place during the seventeenth century in French culinary techniques concern seasoning. ②The strong flavors of the Middle Ages still had some adherents but were increasingly rejected in favor of sauces made with fat, which were thought to preserve more natural flavor. ③While spices still figured in about two-thirds of recipes, a proportion just as high as in the Middle Ages, they were used more sparingly. ④This statement is difficult to prove on the basis of cookbooks alone, because recipes were still imprecise. ⑤However, there are the reports of French travelers, who complained of foreign cooking too spicy to eat. ⑥Such complaints, which do not appear until the mid-seventeenth century, attest to a change of sensibilities.33. According to the passage, during the seventeenth century the French increasingly developed a taste for ______

单选题33. Editors of major United States newsmagazines have been criticized for reducing the amount of space these magazines devote to international news. According to these editors, however, readers are wholly to blame for the reductions. After all, the editors point out, sales of magazine issues that prominently feature international news stories have declined significantly, and declining sales reflect declining reader interest. Yet even if true, this evidence does not refute the contention that editors are merely passive instruments responding to reader interest. And that is clearly an untenable view, since editors can often intensify reader interest in a news topic by giving it frequent coverage. In the argument as a whole, the two highlighted portions play which of the following roles? ______

单选题. ①Wildcats are improbable candidates for domestication. ②Like all felids [cats], wildcats are obligate carnivores, meaning they have a limited metabolic ability to digest anything except proteins. ③Wildcats live a solitary existence and defend exclusive territories, making them more attached to places than to people. ④Furthermore, cats do not perform directed tasks and their actual utility is debatable; even as mousers, in this latter role, terrier dogs and ferrets are preferable. ⑤Accordingly, there is little reason to believe an early agricultural community would have sought out and selected the wildcat as a house pet. ⑥Rather, the best inference is that wildcats exploiting human environments were simply tolerated by people and, over time and space, they gradually diverged from their ''wild" relatives.14. The author would most likely agree that in early agricultural communities cats would have been ______

单选题. ①Recent studies of the gender gap in the history of United States policies tend to focus on candidate choice rather than on registration and turnout. ②This shift in focus from gender inequality in political participation may be due to the finding in several studies of voting behavior in the United States that since 1980, differences in rates of registration and voting between men and women are not statistically significant after controlling for traditional predictors of participation. ③However, Fullerton and Stern argue that researchers have overlooked the substantial gender gap in registration and voting in the South. ④While the gender gap in participation virtually disappeared outside the South by the 1950s, substantial gender differences persisted in the South throughout the 1950s and 1960s, only beginning to decline in 1970s.22. Select the sentence in the passage that offers a possible explanation for a trend.

单选题. ①Soil communities are dependent on plants for organic matter. ②Plants provide organic matter for soil communities through the decomposition of leaf litter, by oozing nutrients from roots, or through other methods of deposition of organic compounds into the soil environments. ③As a result of these diverse methods by which plants supply resources, unique soil communities form under different plant species and under plant communities that differ in composition. ④If a nonnative plant species invades an above-ground community of flora and fauna, it can alter links between the native above-ground community and the below-ground soil community. ⑤For example, an invading nonnative plant could alter the quantity of leaf litter production, which would alter nutrient contributions to the soil.1. According to the passage, plants supply resources to soil communities by which of the following methods? ______

单选题26. The crustaceans known as harpacticoids are very widespread in marine sediments, where they feed on microorganisms by ingesting the sediment particles to which the microorganisms adhere. Heavy metals, such as those found in industrial pollution, readily adhere to sediment particles. Harpacticoids are poisoned by heavy metals but are unaffected by most other pollutants. Therefore the concentration of harpacticoids in an area is a good indication of whether that marine environment contains heavy metals. Which of the following is an assumption on which the argument relies? ______

单选题. ①Among many historians a belief persists that Cotton Mather's biographies of some of the settlers of the Massachusetts Bay Colony (published 1702) are exercises in hagiography, endowing their subjects with saintly piety at the expense of historical accuracy. ②Yet modern studies have profited both from the breadth of information that Mather provides—in, for example, his discussions of colonial medicine—and from his critical observations of such leading figures as Governor John Winthrop. ③Mather's wry humor as demonstrated by his detailed descriptions of events such as Winthrop's efforts to prevent wood-stealing is overlooked by those charging Mather with presenting his subjects as extremely pious. ④The charge also obscures Mather's concern with the settlers' material, not just spiritual, prosperity. ⑤Further, this pejorative view underrates the biographies value as chronicles: Mather amassed all sorts of published and unpublished documents as sources, and his selection of key events shows a marked sensitivity to the nature of the colony's development.50. The primary purpose of the passage is to ______

单选题7. Compared with doctors who see patients only in their offices, doctors who see their patients in the patients ' homes develop a more personal relationship with them. Their patients are also less likely to bring malpractice suits against them. This lower rate of malpractice suits clearly supports the common belief that having a close relationship with a doctor increases a patient's willingness to give that doctor the benefit of the doubt when difficulties arise. Which of the following, if true of doctors who make house calls, most seriously weakens the argument? ______
