Many scholarly discussions of novelist Willa Cather(1873-1947)debate whether Cather belongs more to the nineteenth-century realist tradition or to the modernist revolution of the early twentieth century.While Cather’s preoccupation with nineteenth-century agrarian culture has won her the respect of readers and critics,her distrust of modernity left her with a historically unstable position in the modernist canon.Resistance to the changes wrought by the twentieth century,of course,does not necessarily disqualify one from the“modernist”label.The impulse to reconnect with more primitive,earlier times is a hallmark of modernist aesthetics,shaping the search for meaning in a fragmented,disenchanted,mechanized world.Yet more often than not,[literary critic]Phyllis Rose explains,the early tenth-century atmosphere of experimentation and“making it new”and an attendant critical discourse that“valued complexity,ambiguity,even obscurity”resulted in Cather's labeling as“naively traditional”and“essentially nostalgic and elegiac.”In effect in modernist studies she has been treated as a romantic regional writer,unconcerned with the international terrain so integral to modem thinking-at least until scholars,in the 1980s and 1990s,began reevaluating the historical record,demonstrating her innovative departures from nineteenth-century fiction,including antiheroism,gender-bending episodic narrative,antirealism,simple prose,emphasis on memory and time,and the exploration of immigration,empire,and race.Today it is not uncommon to encounter critics announcing Cather’s newfound canonical status as a modernist-indicated most clearly by her inclusion in works such as The Cambridge Companion to American Modernism published in 2005.
1.The author would be most likely to agree with which of the following claims about Cather's“preoccupation with nineteenth-century agrarian culture?
A.It is regarded by some as evidence of an attitude toward the modern world that is characteristic of many modernist writers. GRE机经
B.Its definitive role in Cather's writing distinguishes Cather from most authors who were considered to be central to the modernist literary tradition.
C.It was clearly an important element of Cather's early fiction but played little role in her later,more mature novels.
D.It has frequently been misinterpreted by the very readers and critics who are most strongly drawn to Cather's fiction
E.Divergent interpretations of it have led critics to form diametrically opposed conclusions about the overall quality of Cather's literary output
2.The author mentions the“critical discourse”primarily to
A.explain why some critics rejected the idea that any particular literary style was uniquely modernist
B.challenge an assumption about the extent to which Cather's novels express a nostalgic view of the past
C.suggest that most of Cather's readers have little in common with the scholarly commentators who have written about her work
D.demonstrate that literary critics’views about Cather's fiction diverge widely on certain points
E.introduce an explanation of criteria used to determine whether Cather belonged in a particular literary category
3.The reference to the highlighted work serves primarily to
A.suggest that no major advances in Cather scholarship have been made since 2005
B.describe an important milestone in a scholarly trend that began in the 1980s
C.cite a publication that has significantly influenced many scholars’views of Cather
D.question the current critical consensus regarding a defining quality of modernism

People who suffer a heart attack on an airplane are at particular risk because of the relatively long time it takes to get them to a hospital.Last year Minerva Airlines trained its cabin crews in the use of on-board defibrillators to restart the heart.Since then,the survival rate for passengers who suffer heart attacks on Minerva flights has increased.Even so,the training might not have contributed to this increase,because ________.
Which of the following most logically completes the passage?
A.the risk of suffering a heart attack increases with age and the average age of passengers has decreased somewhat since last year
B.few other airlines equip their planes with defibrillators or train their cabin crews in the use of them
C.Minerva now offers fewer transoceanic flights than it did last year
D.the electrical impulse delivered by a defibrillator can,if administered to a person with a normal heart rhythm,induce an abnormal heartbeat
E.heart attacks can sometimes be triggered by stress,which is increased by airline travel
Before feminist literary criticism emerged in the 1970s,the nineteenth-century United States writer Fanny Fern was regarded by most critics(when considered at all)as a prototype of weepy sentimentalism—a pious,insipid icon of conventional American culture.Feminist reclamations of Fern,by contrast,emphasize her nonsentimental qualities,particularly her sharply humorous social criticism.Most feminist scholars find it difficult to reconcile Fern’s sardonic social critiques with her effusive celebrations of many conventional values.Attempting to resolve this contradiction,Harris concludes that Fern employed flowery rhetoric strategically to disguise her subversive goals beneath apparent conventionality.However,Tompkins proposes an alternative view of sentimentality itself,suggesting that sentimental writing could serve radical,rather than only conservative ends by swaying readers emotionally,moving them to embrace social change.
Consider each of the choices separately and select all that apply.
1.The passage suggests which of the following about the contradiction mentioned in the highlighted sentence?
A.It was not generally addressed by critics before the 1970s.
B.It is apparent in only a small number of Ferns writings.
C.It has troubled many feminist critics who study Fern.
2.It can be inferred from the passage that Tompkins would be most likely to agree with which of the following about the critics mentioned in the passage?
A.They accurately characterize the overall result Fern is aiming to achieve.
B.They are not as dismissive of Fern as some feminist critics have suggested.
C.They exaggerate the extent to which Fern intended her writing to serve a social purpose.
D.They wrongly assume that sentimental must be a pejorative term.
E.They fail to recognize the role that sentimental rhetoric plays to reader’s emotions.
3.It can be inferred that the author of the passage mentions Fern’s“sharply humorous social criticism”primarily in order to
A.contrast Fern’s apparent intentions with the impression her writing made on Harris
B.suggest that many feminist critics have attributed to Fern intentions that she may not have had
C.identify an aspect of Fern’s writing that strikes some scholars as incompatible with other attributes of her writing
D.help account for the effect Fern's writing had on critics of her own time
E.identify the aspects of Fern's writing for which she was primarily known prior to the 1970s

Most seismologists assume that following a major earthquake and its aftershocks,the fault(a break in Earth’s crust where pressure can trigger an earthquake)will remain quiet until stresses have time to rebuild,typically over hundreds or thousands of years.Recent evidence of subtle interactions between earthquakes may overturn this assumption,however.According to the stress-triggering hypothesis,faults are unexpectedly responsive to subtle stresses they acquire as neighboring faults shift.Rather than simply dissipating,stress relieved during an earthquake travels along the fault,concentrating in sites nearby;even the smallest additional stresses may then trigger another quake along the fault or on a nearby fault.Although scientists have long viewed such subtle interactions as nonexistent,the hypothesis has explained the location and frequency of earthquakes following several destructive quakes in California,Japan,and Turkey.
1.According to the passage,which of the following is an assumption that may be invalidated by recent seismological evidence?
A.Earthquakes are caused by stresses building up in faults within Earth’s crust.
B.Most major earthquakes can be predicted with reasonable accuracy.
C.Faults are highly responsive to even minor stresses in neighboring faults.
D.Most major earthquakes are followed by predictable aftershocks.
E.A fault that has resulted in a major earthquake becomes quiet for a long period.
For the following question,consider each of the choices separately and select all that apply.
2.The passage suggests that most seismologists believe which of the following about fault stresses?
A.They are dissipated when they result in an earthquake.
B.They are transferred between neighboring faults.
C.They will not cause a major earthquake along the same fault in the space of a few years.
