文章：

    In mid-February 1917 a women's movement independent of political affiliation erupted in Line New York City, the stronghold of the Socialist party in the United states. Protesting against the high cost of living, thousands of women refused to buy chickens, fish, and vegetables. The boycott shut down much of the City's foodstuffs marketing for two weeks, riveting public attention on the issue of food prices, which had increased partly as a result of increased exports of food to Europe that had been occurring since the outbreak of the First World War.

    By early 1917 the Socialist party had established itself as a major political presence in New York City. New York Socialists, whose customary spheres of struggle were electoral work and trade union organizing, seized the opportunity and quickly organized an extensive series of cost-of-living protests designed to direct the women's movement toward Socialist goals. Underneath the Socialists' brief commitment to cost-of-living organizing lay a basic indifference to the issue itself. While some Socialists did view price protests as a direct step toward socialism, most Socialists ultimately sought to divert the cost-of-living movement into alternative channels of protest. Union organizing, they argued, was the best method through which to combat the high cost of living. For others, cost-of-living or oganizing was valuable insofar as it led women into the struggle for suffrage, and similarly, the suffrage struggle was valuable insofar as it moved United States society one step closer to socialism.

    Although New York's Socialists saw the cost-of-living issue as, at best ,secondary or tertiary to the real task at hand, the boycotters, by sharp contrast, joined the price protest movement out of an urgent and deeply felt commitment to the cost-of-living issue. A shared experience of swiftly declining living standards caused by rising food prices drove these women to protest. Consumer organizing spoke directly to their daily lives and concerns; they saw cheaper food as a valuable end in itself. Food price protests were these women's way of organizing at their own workplace, as workers whose occupation was shopping and preparing food for their families.

题目：

According to the passage ,most New York  Socialists believed which of the following about the cost-of-living movement?

选项:

A、It was primarily a way to interest women in joining the Socialist party.
B、It was an expedient that was useful only insofar as it furthered other goals.
C、It would indirectly result in an increase in the number of women who belonged to labor unions.
D、It required a long-term commitment but Inevitably represented a direct step Toward socialism.
E、It served as an effective complement to union organizing.

B

Line         Jacob Burckhardt’s view that Renaissance
  European women “stood on a footing of perfect
  equality” with Renaissance men has been repeatedly
  cited by feminist scholars as a prelude to their
(5) presentation of rich historical evidence of women’s
  inequality. In striking contrast to Burckhardt, Joan
  Kelly in her famous 1977 essay, “Did Women Have
  a Renaissance?” argued that the Renaissance was
  a period of economic and social decline for women
(10) relative both to Renaissance men and to medieval
  women. Recently, however, a significant trend
  among feminist scholars has entailed a rejection
  of both Kelly’s dark vision of the Renaissance and
  Burckhardt’s rosy one. Many recent works by these
(15) scholars stress the ways in which differences
  among Renaissance women—especially in terms
  of social status and religion—work to complicate
  the kinds of generalizations both Burckhardt and
  Kelly made on the basis of their observations about
(20) upper-class Italian women.
       The trend is also evident, however, in works
  focusing on those middle- and upper-class
  European women whose ability to write gives them
  disproportionate representation in the historical
(25) record. Such women were, simply by virtue of
  their literacy, members of a tiny minority of the
  population, so it is risky to take their descriptions of
  their experiences as typical of “female experience”
  in any general sense. Tina Krontiris, for example, in
(30) her fascinating study of six Renaissance women
  writers, does tend at times to conflate “women” and
  “women writers,” assuming that women’s gender,
  irrespective of other social differences, including
  literacy, allows us to view women as a homogeneous
(35) social group and make that group an object of
  analysis. Nonetheless, Krontiris makes a significant
  contribution to the field and is representative of
  those authors who offer what might be called a
  cautiously optimistic assessment of Renaissance
(40) women’s achievements, although she also stresses
  the social obstacles Renaissance women faced
  when they sought to raise their “oppositional
  voices.” Krontiris is concerned to show women
  intentionally negotiating some power for themselves
(45) (at least in the realm of public discourse) against
  potentially constraining ideologies, but in her sober
  and thoughtful concluding remarks, she suggests
  that such verbal opposition to cultural stereotypes
  was highly circumscribed; women seldom attacked
(50) the basic assumptions in the ideologies that
  oppressed them.


题目：

The last sentence in the passage serves primarily to

选项:

A、suggest that Krontiris’s work is not representative of recent trends among feminist scholars
B、undermine the argument that literate women of the Renaissance sought to oppose social constraints imposed on them
C、show a way in which Krontiris’s work illustrates a “cautiously optimistic” assessment of Renaissance women’s achievements
D、summarize Krontiris’s view of the effect of literacy on the lives of upper- and middle-class Renaissance women
E、illustrate the way in which Krontiris’s study differs from the studies done by Burckhardt and Kelly

The following appeared in a memorandum from a regional supervisor of post office operations.
 
"During a two-week study of pestal operations, the Presto City post office handled about twice as many items as the Lento City post office, even though the cities are about the same size. Moreover, customer satisfaction appears to be higher in Presto City, since the study found fewer complaints regarding the Presto city post office. Therefore, the postmasters at these two offices should exchange assignments: the Presto Coty postmaster will solve the problems of inefficiency and customer dissatisfaction at the Lento City office while the Lento City postmaster learns first-hand the superior methods of Presto City."

Line         Frazier and Mosteller assert that medical research
  could be improved by a move toward larger, simpler
  clinical trials of medical treatments. Currently,
  researchers collect far more background information
(5) on patients than is strictly required for their trials—
  substantially more than hospitals collect—thereby
  escalating costs of data collection, storage, and
  analysis. Although limiting information collection
  could increase the risk that researchers will overlook
(10) facts relevant to a study, Frazier and Mosteller
  contend that such risk, never entirely eliminable from
  research, would still be small in most studies. Only
  in research on entirely new treatments are new and
  unexpected variables likely to arise.
(15)      Frazier and Mosteller propose not only that
  researchers limit data collection on individual
  patients but also that researchers enroll more
  patients in clinical trials, thereby obtaining a more
  representative sample of the total population with
(20) the disease under study. Often researchers restrict
  study participation to patients who have no ailments
  besides those being studied. A treatment judged
  successful under these ideal conditions can then be
  evaluated under normal conditions. Broadening the
(25) range of trial participants, Frazier and Mosteller
  suggest, would enable researchers to evaluate a
  treatment’s efficacy for diverse patients under various
  conditions and to evaluate its effectiveness for
  different patient subgroups. For example, the value
(30) of a treatment for a progressive disease may vary
  according to a patient’s stage of disease. Patients’
  ages may also affect a treatment’s efficacy.


题目：

Which of the following can be inferred from the passage about a study of the category of patients referred to in lines 20–22 ?

选项:

A、Its findings might have limited applicability.
B、It would be prohibitively expensive in its attempt to create ideal conditions.
C、It would be the best way to sample the total population of potential patients.
D、It would allow researchers to limit information collection without increasing the risk that important variables could be overlooked.
E、Its findings would be more accurate if it concerned treatments for a progressive disease than if it concerned treatments for a nonprogressive disease.

文章：

Line         In an effort to explain why business acquisitions
  often fail, scholars have begun to focus on the role
  of top executives of acquired companies. Acquired
  companies that retain their top executives tend to
(5) have more successful outcomes than those that do
  not. Furthermore, existing research suggests that
  retaining the highest-level top executives, such as the
  CEO (chief executive officer) and COO (chief operating
  officer), is related more positively to postacquisition
(10) success than retaining lower-ranked top executives.
  However, this explanation, while insightful, suffers from
  two limitations. First, the focus on positional rank does
  not recognize the variation in length of service that
  may exist in top executive posts across companies,
(15) nor does it address which particular top executives
  (with respect to length of service) should be retained
  to achieve a successful acquisition outcome. Second,
  the relationship between retained top executives and
  acquisition outcomes offered by existing research
(20) is subject to opposing theoretical explanations
  related to length of service. The resource-based view
  (RBV) suggests that keeping acquired company top
  executives with longer organizational tenure would lead
  to more successful outcomes, as those executives
(25) have idiosyncratic and nontransferable knowledge
  of the acquired company that would be valuable for
  the effective implementation of the acquisition. The
  opposing position, offered by the upper echelons
  perspective (UEP), suggests that retaining top
(30) executives having short organizational tenure would
  lead to more successful outcomes, as they would have
  the adaptability to manage most effectively during the
  uncertainty of the acquisition process.
       Responding to these limitations, Bergh conducted
(35) a study of executive retention and acquisition
  outcome that focused on the organizational tenure of
  retained company top executives in 104 acquisitions,
  followed over 5 years. Bergh considered the
  acquisition successful if the acquired company was
(40) retained and unsuccessful if it was divested. Bergh’s
  findings support the RBV position. Apparently, the
  benefits of long organizational tenure lead to more
  successful outcomes than the benefits of short
  organizational tenure. While longer tenured top
(45) executives may have trouble adapting to change, it
  appears that their perspectives and knowledge bases
  offer unique value after the acquisition. Although
  from the UEP position it seems sensible to retain
  less tenured executives and allow more tenured
(50) ones to leave, such a strategy appears to lower the
  probability of acquisition success.


题目：

According to the passage, the research mentioned in line 6 suggests which of the following about lower-ranked top executives and postacquisition success?

选项:

A、Given that these executives are unlikely to contribute to postacquisition success, little effort should be spent trying to retain them.
B、The shorter their length of service, the less likely it is that these executives will play a significant role in postacquisition success.
C、These executives are less important to postacquisition success than are more highly ranked top executives.
D、If they have long tenures, these executives may prove to be as important to postacquisition success as are more highly ranked top executives.
E、Postacquisition success is unlikely if these executives are retained.

Art historian: Unlike many artistic traditions that sought to depict plants native to the local area in a seasonally appropriate way (for example, depicting scenes of spring with the plants in the appropriate stages of development for that season), seventeenth-century Dutch artists specializing in flower paintings almost exclusively chose to depict exotic species of flowers from outside the local area. Painting such species was worthwhile primarily because the art-buying public had developed a strong preference for images of the exotic. The great botanical centers of the time gave the artists direct access to such flowers, which the artists would freely combine in a single painting, regardless of whether the combined species occurred together in the wild, and depicted each in full bloom, regardless of whether those species bloomed at the same time in nature.

Statement: The art historian makes the point that the species of flowers these Dutch artists chose to paint were 1 largely because the species were 2 .

Select for 1 and for 2 the options that complete the statement so that it is most strongly supported by the information provided. Make only two selections, one in each column.

Tiger beetles are such fast runners that they can capture virtually any nonflying insect.  However, when running toward an insect, the beetles intermittently stop, and then, a moment later, resume their attack.  Perhaps they cannot maintain their pace and must pause for a moment's rest; but an alternative hypothesis is that while running tiger beetles are unable to process the resulting rapidly changing visual information, and so quickly go blind and stop.
