Current feminist theory, in validating women’s own stories of their experience, has encouraged scholars of women’s history to view the use of women’s oral narratives as the methodology, next to the use of women’s written autobiography, that brings historians closest to the "reality" of women’s lives. Such narratives, unlike most standard histories, represent experience from the perspective of women, affirm the importance of women’s contributions, and furnish present-day women with historical continuity that is essential to their identity, individually and collectively.

Scholars of women’s history should, however, be as cautious about accepting oral narratives at face value as they already are about written memories. Oral narratives are no more likely than are written narratives to provide a disinterested commentary on events or people. Moreover, the stories people tell to explain themselves are shaped by narrative devices and storytelling conventions, as well as by other cultural and historical factors, in ways that the storytellers may be unaware of. The political rhetoric of a particular era, for example, may influence women’s interpretations of the significance of their experience. Thus a woman who views the Second World War as pivotal in increasing the social acceptance of women’s paid work outside the home may reach that conclusion partly and unwittingly because of wartime rhetoric encouraging a positive view of women’s participation in such work.

题目：

According to the passage, each of the following is a difference between women’s oral narratives and most standard histories EXCEPT:

选项:

A、Women's oral histories validate the significance of women's achievements.Women's oral histories depict experience from the point of view of women.
B、Women's oral histories acknowledge the influence of well-known women.
C、Women's oral histories present today's women with a sense of their historical relationship to women of the past.
D、Women's oral histories are crucial to the collective identity of today's women.

答案:

C

Line         During the 1980s, many economic historians
  studying Latin America focused on the impact of
  the Great Depression of the 1930s. Most of these
  historians argued that although the Depression
(5) began earlier in Latin America than in the United
  States, it was less severe in Latin America and did
  not significantly impede industrial growth there.
  The historians’ argument was grounded in national
  government records concerning tax revenues and
(10) exports and in government-sponsored industrial
  censuses, from which historians have drawn
  conclusions about total manufacturing output
  and profit levels across Latin America. However,
  economic statistics published by Latin American
(15) governments in the early twentieth century are
  neither reliable nor consistent; this is especially
  true of manufacturing data, which were gathered
  from factory owners for taxation purposes and
  which therefore may well be distorted. Moreover,
(20) one cannot assume a direct correlation between
  the output level and the profit level of a given
  industry as these variables often move in opposite
  directions. Finally, national and regional economies
  are composed of individual firms and industries,
(25) and relying on general, sweeping economic
  indicators may mask substantial variations among
  these different enterprises. For example, recent
  analyses of previously unexamined data on textile
  manufacturing in Brazil and Mexico suggest that the
(30) Great Depression had a more severe impact on this
  Latin American industry than scholars
  had recognized.


题目：

Which of the following, if true, would most strengthen the author’s assertion regarding economic indicators in lines 25–27 ?

选项:

A、During an economic depression, European textile manufacturers’ profits rise while their industrial output remains steady.
B、During a national economic recession, United States microchips manufacturers’ profits rise sharply while United States steel manufacturers’ profits plunge.
C、During the years following a severe economic depression, textile manufacturers’ output levels and profit levels increase in Brazil and Mexico but not in the rest of Latin America.
D、Although Japanese industry as a whole recovers after an economic recession, it does not regain its previously high levels of production.
E、While European industrial output increases in the years following an economic depression, total output remains below that of Japan or the United States.

B

题目：

Last year Comfort Airlines had twice as many delayed flights as the year before, but the number of complaints from passengers about delayed flights went up three times. It is unlikely that this disproportionate increase in complaints was rooted in an increase in overall dissatisfaction with the service Comfort Airlines provides, since the airline made a special effort to improve other aspects of its service last year.

Which of the following, if true, most helps to explain the disproportionate increase in customer complaints?

    The Gross Domestic Product. (GDP), which measures the dollar value of finished goods and services produced by an economy during a given period, serves as the chief indicator of the economic well-being of the United States. The GDP assumes that the economic significance of goods and services lies solely in their price, and that these goods and services add to the national well-being, not because of any intrinsic value they may possess, but simply because they were produced and bought. Additionally, only those goods and services involved in monetary transactions are included in the GDP. Thus, the GDP ignores the economic utility of such things as a clean environment and cohesive families and communities, It is therefore not merely coincidental, since nationalpolicies in capitalist and noncapitalist countries alike are dependent on indicators such as the GDP, that both the environment and the social structure have been eroded in recent decades not only does the GDP mask this erosion, it can actually portray it as an economic gain: an oil spill off a coastal region "adds" to the GDP because it generates commercial activity. In short, the nation's central measure of economic well-being works like a calculating machine that adds but cannot subtract.

题目：

Which of the following best describes the function of the second sentence of the passage (the highlighted text) in the context of the passage as a whole?

选项:

A、It describes an assumption about the GDP that is defended in the course of the passage.
B、It contributes to a discussion of the origins of the GDP.
C、It clarifies a common misconception about the use of the GDP.
D、It identifies a major flaw in the GDP.
E、It suggests a revision to the method of calculating the GDP.

A

文章：

Many United States companies believe that the rising cost of employees' health care benefits has hurt the country's competitive position in the global market by raising production costs and thus increasing the prices of exported and domestically sold goods.  As a result, these companies have shifted health care costs to employees in the form of wage deductions or high deductibles.  This strategy, however, has actually hindered companies' competitiveness.  For example, cost shifting threatens employees' health because many do not seek preventive screening.  Also, labor relations have been damaged:  the percentage of strikes in which health benefits were a major issue rose from 18 percent in 1986 to 78 percent in 1989.
 
Health care costs can be managed more effectively if companies intervene in the supply side of health care delivery just as they do with other key suppliers:  strategies used to procure components necessary for production would work in procuring health care.  For example, the make/buy decision--the decision whether to produce or purchase parts used in making a product--can be applied to health care.  At one company, for example, employees receive health care at an on-site clinic maintained by the company.  The clinic fosters morale, resulting in a low rate of employees leaving the company.  Additionally, the company has constrained the growth of health care costs while expanding medical services.

题目：

Which of the following, if true, would provide the most support for the author's view about intervening on the supply side of health care?

选项:

A、Most companies do not have enough employees to make on-site clinics cost-effective.
B、Many companies with on-site clinics offer their employees the option of going outside the company's system to obtain health care.
C、The costs of establishing and running an on-site clinic are demonstrably higher than the costs of paying for health care from an outside provider.
D、Companies with health care clinics find that employees are unwilling to assist in controlling the costs of health care.
E、Employees at companies with on-site clinics seek preventive screening and are thus less likely to delay medical treatment.

E

文章：

In parts of South America, vitamin-A deficiency is a serious health problem, especially among children. In one region, agriculturists hope to improve nutrition by encouraging farmers to plant a new variety of sweet potato called SPK004 that is rich in betacarotene, which the body converts into vitamin A. The plan has good chances of success, since sweet potato is a staple of the region's diet and agriculture, and the varieties currently grown contain little beta-carotene.

题目：

Which of the following, if true, most strongly supports the prediction that the plan will succeed?

选项:

A、There are other vegetables currently grown in the region that contain more beta-carotene than the currently cultivated varieties of sweet potato do. The flesh of SPK004 differs from that of the currently cultivated sweet potatoes in color and texture, so traditional foods would look somewhat different when prepared from SPK004.
B、For successful cultivation of SPK004, a soil significantly richer in nitrogen is needed than is needed for the varieties of sweet potato currently cultivated in the region. 
C、There are no other varieties of sweet potato that are significantly richer in beta-carotene than SPK004 is. 
D、The currently cultivated varieties of sweet potato contain no important nutrients that SPK004 lacks.

E

题目：

Farmer: Worldwide, just three grain crops—rice, wheat, and corn—account for most human caloric intake. To maintain this level of caloric intake and also keep pace with global population growth, yields per acre from each of these crops will have to increase at least 1.5 percent every year, given that the supply of cultivated land is diminishing. Therefore, the government should increase funding for research into new ways to improve yields.

Which of the following is an assumption on which the farmer's argument depends?

选项:

A、It is solely the government's responsibility to ensure that the amount of rice, wheat, and corn produced worldwide keeps pace with global population growth.
B、Increasing government funding for research into new ways to improve the yields per acre of rice, wheat, and corn crops would help to increase total worldwide annual production of food from these crops.
C、Increasing the yields per acre of rice, wheat, and corn is more important than increasing the yields per acre of other crops.
D、Current levels of funding for research into ways of improving grain crop yields per acre have enabled grain crop yields per acre to increase by more than 1.5 percent per year worldwide.
E、In coming decades, rice, wheat, and corn will become a minor part of human caloric intake, unless there is government-funded research to increase their yields per acre.

B

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.
 
Which of the following, if discovered in experiments using artificially moved prey insects, would support one of the two hypotheses and undermine the other?
