新GRE考试阅读理解练习及答案（4）
In eighteenth-century France and England, reformers rallied around egalitarian ideals, but few reformers advocated higher education for women. Although the public decried women’s lack of education, it did not encourage learning for its own sake for women. In spite of the general prejudice against learned women, there was one place where women could exhibit their erudition: the literary salon. Many writers have defined the woman’s role in the salon as that of an intelligent hostess, but the salon had more than a social function for women. It was an informal university, too, where women exchanged ideas with educated persons, read their own works and heard those of others, and received and gave criticism. In the 1750’s, when salons were firmly established in France, some English women, who called themselves “Bluestocking,” followed the example of the salonnieres (French salon hostesses)and formed their own salons. Most Bluestockings did not wish to mirror the salonnieres; they simply desired to adapt a proven formula to their own purpose—the elevation of women’s status through moral and intellectual training. Differences in social orientation and background can account perhaps for differences in the nature of French and English salons. The French salon incorporated aristocratic attitudes that exalted courtly pleasure and emphasized artistic accomplishments. The English Bluestockings, originating from a more modest background, emphasized learning and work over pleasure. Accustomed to the regimented life of court circles, salonnieres tended toward formality in their salons. The English women, though somewhat puritanical, were more casual in their approach. At first, the Bluestockings did imitate the salonnieres by including men in their circles. However, as they gained cohesion, the Bluestockings came to regard themselves as a women’s group and to possess a sense of female solidarity lacking in the salonnieres, who remained isolated from one another by the primacy each held in her own salon. In an atmosphere of mutual support, the Bluestockings went beyond the salon experience. They traveled, studied, worked, wrote for publication, and by their activities challenged the stereotype of the passive woman. Although the salonnieres were aware of sexual inequality, the narrow boundaries of their world kept their intellectual pursuits within conventional limits. Many salonnieres, in fact, camouflaged their nontraditional activities behind the role of hostess and deferred to men in public. Though the Bluestockings were trailblazers when compared with the salonnieres, they were not feminists. They were too traditional, too hemmed in by their generation to demand social and political rights. Nonetheless, in their desire for education, their willingness to go beyond the confines of the salon in pursuing their interests, and their championing of unity among women, the Bluestockings began the process of questioning women’s role in society。

GRE（VERBAL）阅读模拟试卷4(题后含答案及解析) 题型有：1. PART ONEPART ONE （Time：30 minutes 38 Questions）SECTION 3Directions: Each passage in this group is followed by questions based on its content. After reading a passage, choose the best answer to each question. Answer all questions following a passage on the basis of what is stated or implied in the passage.Late-eighteenth-century English cultural authorities seemingly concurred that women readers should favor history, seen as edifying, than fiction, which was regarded as frivolous and reductive. Readers of Marry Ann Hanway’s novel Andrew Stewart, or the Northern Wanderer, learning that its heroine delights in David Hume’s and Edward Gibbon’s histories, could conclude that she was more virtuous and intelligent than her sister, who disdains such reading. Likewise, while the na?ve, novel-addicted protagonist of Jane Austen’s Northanger Abbey, Catherine Morland, finds history a chore, the sophisticated, sensible character Eleanor Tilney enjoys it more than she does the Gothic fiction Catherine prefers. Yet in both cases, the praise of history is more double-edged than it might actually appear. Many readers have detected a protofeminist critique of history in Catherine’s protest that she dislikes reading books filled with men “and hardly any women at all.”Hanway, meanwhile, brings a controversial political edge to her heroine’s reading, listing the era’s two most famous religious skeptics among her preferred authors. While Hume’s history was generally seen as being less objectionable as his philosophy, there were widespread doubts about his moral soundness even as a historian by the time that Hanway was writing, and Gibbon’s perceived tendency to celebrate classical paganism sparked controversy from the first appearance of his history of Rome.1．The author’s primary purpose is thatA．the evidence used in support of a particular argument is questionableB．a distinction between two genres of writing has been overlookedC．a particular issue is more complex than it might appearD．two apparently different works share common featuresE．two eighteenth-century authors held significantly different attitudes toward a particular正确答案：A解析：A选项中的a particular argument指的是文化权威们认为“女人应该多读历史”的观点，evidence指的是第二、三句。

(10)if committed by adults, these actions are not even considered prosecutable; if committed by juvenile males, they have traditionally been looked on leniently by the courts. thus ironically, the plight of female delinquents receives (15)little scrutiny because they are accused of committing relatively minor offenses. second, the courts have long unjustified so-called preventive intervention into the lives of young females viewed as antisocial with the rationale that(20)women are especially vulnerable. traditional stereotypes of women as the weaker and more dependent sex have led to earlier intervention and longer periods of misdirected supervision for female delinquents than for males.17. which of the following statements best expresses the irony pointed out by the authors in lines 13-16 of the passage?(a) female delinquents tend to commit victimless crimes more frequently than their male counterparts.(b) the predicament of male delinquents receives more attention than that of females because males are accused of more serious crimes.(c) adults are frequently punished less severely than adolescents for committing more serious crimes.(d) the juvenile justice system cannot correct its biases because it does not even recognize them.(e) although the number of female delinquents is steadily increasing, the crimes of which they are accused are not particularly serious.18. it can be inferred from the passage that the authors believe traditional stereotypes of women to be(a) frequently challenged(b) persistently inexplicable(c) potentially harmful(d) rapidly changing(e) habitually disregarded19. the passage suggests that scholars in criminal justice could be criticized for which of the following?(a) underestimating the seriousness of juvenile crime(b) rationalizing the distinction made between juveniles and adults in the legal system(c) concerning themselves too little with the prevention of juvenile delinquency(d) focusing on those whose crimes have involved damage to persons or property(e) failing to point out injustices in the correctional systemscattered around the globe are more than one hundred regions of volcanic activity known as hot spots. unlike most volcanoes, hot spots are rarely found along the boundaries of the continental and oceanic plates that comprise the earth's crust; most hot spots lie deep in the interior of plates and are anchored deep in the layers of the earth's surface. hot spots are also distinguished from other volcanoes by their lavas, which contain greater amounts of alkali metals than do thosefrom volcanoes at plate margins.in some cases, plates moving past hot spots have left trails of extinct volcanoes in much the same way that wind passing over a chimney carries off puffs of smoke. it appears that the hawaiian islands were created in such a manner by a single source of lava, welling up from a hot spot, over which the pacific ocean plate passed on a course roughly from the east toward the northwest, carrying off a line of volcanoes of increasing age. two other pacific island chains- the austral ridge and the tuamotu ridge-parallel the configuration of the hawaiian chain; they are also aligned from the east toward the northwest, with the most recent volcanic activity near their eastern terminuses.that the pacific plate and the other plates are moving is now beyond dispute; the relative motion of the plates has been reconstructed in detail. however, the relative motion of the plates with respect to the earth's interior cannot be determined easily. hot spots provide the measuring instruments for resolving the question of whether two continental plates are moving in opposite directions or whether one is stationary and the other is drifting away from it. the most compelling evidence that a continental plat isstationary is that, at some hot spots, lavas of several ages are superposed instead of being spread out in chronological sequence. of course, reconstruction of plate motion from the tracks of hot-spot volcanoes assumes that hot spots are immobile, or nearly so. several studies support such an assumption, including one that has shown that prominent hot spots through- out the world seem not to have moved during the past ten million years.beyond acting as frames of reference, hot spots apparently influence the geophysical processes that propel the plates across the globe. when a continental plate comes to rest over a hot spot, material welling up from deeper layers forms a broad dome that, as it grows, develops deep fissures. in some instances, the continental plate may rupture entirely along some of the fissures so that hot spot initiates the formation of a new ocean. thus, just as earlier theories have explained the mobility of the continental plates, so hot-spot activity may suggest a theory to explain their mutability.20. the primary purpose of the passage is to(a) describe the way in which hot spots influence the extinction of volcanoes(b) describe and explain the formation of the oceans andcontinents(c) explain how to estimate the age of lava flows from extinct volcanoes(d) describe hot spots and explain how they appear to influence and record the motion of plates(e) describe the formation and orientation of island chains in the pacific ocean21. according to the passage, hot spots differ from most volcanoes in that hot spots(a) can only be found near islands(b) are active whereas all other volcanoes are extinct(c) are situated closer to the earth's surface(d) can be found along the edges of the plates(e) have greater amounts of alkali metals in their lavas22. it can be inferred from the passage that evidence for the apparent course of the pacific plate has been provided by the(a) contours of the continents.(b) dimensions of ocean hot spots(c) concurrent movement of two hot spots(d) pattern of fissures in the ocean floor(e) configurations of several mid-ocean island chains23. it can be inferred from the passage that the spreading out of lavas of different ages at hot spots indicates that a(a) hot spot is active(b) continental plate has moved(c) continental rupture is imminent(d) hot spot had been moving very rapidly(e) volcano contains large concentrations of alkali metals24. the passage suggests which of the following about the hawaiian islands, the austral ridge, and the tuamotu ridge?(a) the three chains of islands are moving east- ward.(b) all the islands in the three chains have stopped moving.(c) the three islands chains are a result of the same plate movement.(d) the hawaiian islands are receding from the other two island chains at a relatively rapid rate.(e) the austral ridge and the tuamotu ridge chains have moved closer together whereas the hawaiian islands have remained stationary.25. which of the following, if true, would best support the author's statement that hot-spot activity may explain the mutability of continental plates?(a) hot spots move more rapidly than the continental and oceanic plates.(b) hot spots are reliable indicators of the age of continental plates.(c) hot spots are regions of volcanic activity found only in the interiors of the continental plates.(d) the alignment of hot spots in the pacific. ocean parallels the alignment of pacific ocean islands.(e) the coastlines of africa and south america suggest that they may once have constituted a single continent that ruptured along a line of hot spots.26. the author's argument that hot spots can be used to reconstruct the movement of continental plates is weakened by the fact that(a) hot spots are never found at the boundaries of plates(b) only extinct volcanoes remain after a plate moves over a hot spot(c) lava flow patterns for all hot spots have not been shown to be the same(d) the immobility or near immobility of hot spots has not been conclusively proven(e) the changing configurations of islands makepinpointing the locations of hot spots difficult27. the author's

(10)if committed by adults, these actions are not even considered prosecutable; if committed by juvenile males, they have traditionally been looked on leniently by the courts. thus ironically, the plight of female delinquents receives (15)little scrutiny because they are accused of committing relatively minor offenses. second, the courts have long unjustified so-called preventive intervention into the lives of young females viewed as antisocial with the rationale that(20)women are especially vulnerable. traditional stereotypes of women as the weaker and more dependent sex have led to earlier intervention and longer periods of misdirected supervision for female delinquents than for males.17. which of the following statements best expresses the irony pointed out by the authors in lines 13-16 of the passage?(a) female delinquents tend to commit victimless crimes more frequently than their male counterparts.(b) the predicament of male delinquents receives more attention than that of females because males are accused of more serious crimes.(c) adults are frequently punished less severely than adolescents for committing more serious crimes.(d) the juvenile justice system cannot correct its biases because it does not even recognize them.(e) although the number of female delinquents is steadily increasing, the crimes of which they are accused are not particularly serious.18. it can be inferred from the passage that the authors believe traditional stereotypes of women to be(a) frequently challenged(b) persistently inexplicable(c) potentially harmful(d) rapidly changing(e) habitually disregarded19. the passage suggests that scholars in criminal justice could be criticized for which of the following?(a) underestimating the seriousness of juvenile crime(b) rationalizing the distinction made between juveniles and adults in the legal system(c) concerning themselves too little with the prevention of juvenile delinquency(d) focusing on those whose crimes have involved damage to persons or property(e) failing to point out injustices in the correctional systemscattered around the globe are more than one hundred regions of volcanic activity known as hot spots. unlike most volcanoes, hot spots are rarely found along the boundaries of the continental and oceanic plates that comprise the earth's crust; most hot spots lie deep in the interior of plates and are anchored deep in the layers of the earth's surface. hot spots are also distinguished from other volcanoes by their lavas, which contain greater amounts of alkali metals than do thosefrom volcanoes at plate margins.in some cases, plates moving past hot spots have left trails of extinct volcanoes in much the same way that wind passing over a chimney carries off puffs of smoke. it appears that the hawaiian islands were created in such a manner by a single source of lava, welling up from a hot spot, over which the pacific ocean plate passed on a course roughly from the east toward the northwest, carrying off a line of volcanoes of increasing age. two other pacific island chains- the austral ridge and the tuamotu ridge-parallel the configuration of the hawaiian chain; they are also aligned from the east toward the northwest, with the most recent volcanic activity near their eastern terminuses.that the pacific plate and the other plates are moving is now beyond dispute; the relative motion of the plates has been reconstructed in detail. however, the relative motion of the plates with respect to the earth's interior cannot be determined easily. hot spots provide the measuring instruments for resolving the question of whether two continental plates are moving in opposite directions or whether one is stationary and the other is drifting away from it. the most compelling evidence that a continental plat isstationary is that, at some hot spots, lavas of several ages are superposed instead of being spread out in chronological sequence. of course, reconstruction of plate motion from the tracks of hot-spot volcanoes assumes that hot spots are immobile, or nearly so. several studies support such an assumption, including one that has shown that prominent hot spots through- out the world seem not to have moved during the past ten million years.beyond acting as frames of reference, hot spots apparently influence the geophysical processes that propel the plates across the globe. when a continental plate comes to rest over a hot spot, material welling up from deeper layers forms a broad dome that, as it grows, develops deep fissures. in some instances, the continental plate may rupture entirely along some of the fissures so that hot spot initiates the formation of a new ocean. thus, just as earlier theories have explained the mobility of the continental plates, so hot-spot activity may suggest a theory to explain their mutability.20. the primary purpose of the passage is to(a) describe the way in which hot spots influence the extinction of volcanoes(b) describe and explain the formation of the oceans andcontinents(c) explain how to estimate the age of lava flows from extinct volcanoes(d) describe hot spots and explain how they appear to influence and record the motion of plates(e) describe the formation and orientation of island chains in the pacific ocean21. according to the passage, hot spots differ from most volcanoes in that hot spots(a) can only be found near islands(b) are active whereas all other volcanoes are extinct(c) are situated closer to the earth's surface(d) can be found along the edges of the plates(e) have greater amounts of alkali metals in their lavas22. it can be inferred from the passage that evidence for the apparent course of the pacific plate has been provided by the(a) contours of the continents.(b) dimensions of ocean hot spots(c) concurrent movement of two hot spots(d) pattern of fissures in the ocean floor(e) configurations of several mid-ocean island chains23. it can be inferred from the passage that the spreading out of lavas of different ages at hot spots indicates that a(a) hot spot is active(b) continental plate has moved(c) continental rupture is imminent(d) hot spot had been moving very rapidly(e) volcano contains large concentrations of alkali metals24. the passage suggests which of the following about the hawaiian islands, the austral ridge, and the tuamotu ridge?(a) the three chains of islands are moving east- ward.(b) all the islands in the three chains have stopped moving.(c) the three islands chains are a result of the same plate movement.(d) the hawaiian islands are receding from the other two island chains at a relatively rapid rate.(e) the austral ridge and the tuamotu ridge chains have moved closer together whereas the hawaiian islands have remained stationary.25. which of the following, if true, would best support the author's statement that hot-spot activity may explain the mutability of continental plates?(a) hot spots move more rapidly than the continental and oceanic plates.(b) hot spots are reliable indicators of the age of continental plates.(c) hot spots are regions of volcanic activity found only in the interiors of the continental plates.(d) the alignment of hot spots in the pacific. ocean parallels the alignment of pacific ocean islands.(e) the coastlines of africa and south america suggest that they may once have constituted a single continent that ruptured along a line of hot spots.26. the author's argument that hot spots can be used to reconstruct the movement of continental plates is weakened by the fact that(a) hot spots are never found at the boundaries of plates(b) only extinct volcanoes remain after a plate moves over a hot spot(c) lava flow patterns for all hot spots have not been shown to be the same(d) the immobility or near immobility of hot spots has not been conclusively proven(e) the changing configurations of islands makepinpointing the locations of hot spots difficult27. the author's
