题目：

The introduction of new drugs into the market is frequently prevented by a shortage of human subjects for the clinical trials needed to show that the drugs are safe and effective. Since the lives and health of people in future generations may depend on treatments that are currently experimental, practicing physicians are morally in the wrong when, in the absence of any treatment proven to be effective, they fail to encourage suitable patients to volunteer for clinical trials.

Which of the following, if true, casts most doubt on the conclusion of the argument?

选项:

A、Many drugs undergoing clinical trials are intended for the treatment of conditions for which there is currently no effective treatment.
B、Patients do not share the physician’s professional concern for public health, but everyone has a moral obligation to alleviate suffering when able to do so.
C、Usually, half the patients in a clinical trial serve as a control group and receive a nonactive drug in place of the drug being tested.
D、An experimental drug cannot legally be made available to patients unless those patients are subjects in clinical trials of the drug.
E、Physicians have an overriding moral and legal duty to care for the health and safety of their current patients.

E

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：

It can be inferred that both Burckhardt and Kelly have been criticized by the scholars mentioned in line 12 for which of the following?

选项:

A、Assuming that women writers of the Renaissance are representative of Renaissance women in general
B、Drawing conclusions that are based on the study of an atypical group of women
C、Failing to describe clearly the relationship between social status and literacy among Renaissance women
D、Failing to acknowledge the role played by Renaissance women in opposing cultural stereotypes
E、Failing to acknowledge the ways in which social status affected the creative activities of Renaissance women

文章：

The identification of femininity with morality and a belief in the innate moral superiority of women were fundamental to the cult of female domesticity in the nineteenth-century United States.  Ironically, this ideology of female benevolence empowered women in the realm of social activism, enabling them to escape the confines of their traditional domestic spheres and to enter prisons, hospitals, battlefields, and slums.  By following this path, some women came to wield considerable authority in the distribution of resources and services in their communities.
 
The sentimentalized concept of female benevolence bore little resemblance to women's actual work, which was decidedly unsentimental and businesslike, in that it involved chartering societies, raising money, and paying salaries.  Moreover, in the face of legal limitations on their right to control money and property, women had to find ingenious legal ways to run and finance organized philanthropy.  In contrast to the day-to-day reality of this work, the idealized image of female benevolence lent a sentimental and gracious aura of altruism to the very real authority and privilege that some women commanded--which explains why some women activists clung tenaciously to this ideology.  But clinging to this ideology also prevented these women from even attempting to gain true political power because it implied a moral purity that precluded participation in the messy world of partisan politics.

题目：

Information in the passage suggests that the author would be most likely to agree with which of the following statements concerning the cult of female domesticity?

选项:

A、The cult of female domesticity developed independently of the concept of female benevolence.
B、The cult of female domesticity was incompatible with women's participation in social activism.
C、The cult of female domesticity incorporated ideological elements that actually helped some women to escape from their traditional domestic roles.
D、The original motivation behind the promotion of the cult of female domesticity was to exclude women from partisan politics.
E、The growth of organized philanthropy in the nineteenth-century United States is ultimately attributable to the cult of female domesticity.

题目：

Suriland cannot both export wheat and keep bread plentiful and affordable in Suriland. Accordingly, Suriland’s wheat farmers are required to sell their crop to the government, which pays them a dollar per bushel less than the price on the world market. Therefore, if the farmers could sell their wheat on the world market, they would make a dollar per bushel more, less any additional transportation and brokerage costs they would have to pay.

Which of the following, if true, most seriously weakens the argument?

选项:

A、Suriland’s wheat farmers have higher production costs than do farmers in many other wheat-producing countries.
B、Sale of a substantial proportion of Suriland’s wheat crop on the world market would probably depress the price of wheat.
C、The transportation and brokerage costs that Suriland’s farmers would face if they sold their wheat outside Suriland could amount to almost a dollar per bushel.
D、Suriland is surrounded by countries that do not import any wheat.
E、The price of a bushel of wheat on the world market occasionally drops below the average cost of producing a bushel of wheat in Suriland.

文章：

    By the sixteenth century, the Incas of South America ruled an empire that extended along the Pacific coast and Andean highlands from what is now Ecuador to central Chile. While most of the Incas were self-sufficient agriculturists, the inhabitants of the highland basins above 9,000 feet were constrained by the kinds of crops they could cultivate. Whereas 95 percent of the principal Andean food crops can be cultivated below 3,000 feet, only 20 percent reproduce readily above 9,000 feet. Given this unequal resource distribution, highland Incas needed access to the products of lower, warmer climatic zones in order to enlarge the variety and quantity of their foodstuffs. In most of the preindustrial world, the problem of different resource distribution was resolved by long-distance trade networks over which the end consumer exercised little control. Although the peoples of the Andean highlands participated in such networks, they relied primarily on the maintenance of autonomous production forces in as many ecological zones as possible. The commodities produced in these zones were extracted, processed, and transported entirely by members of a single group.

    This strategy of direct access to a maximum number of ecological zones by a single group is called vertical economy. Even today, one can see Andean communities maintaining use rights simultaneously to pasturelands above 12,000 feet, to potato fields in basins over 9,000 feet, and to plots of warm-land crops in regions below 6,000 feet. This strategy has two principal variations. The first is "compressed verticality," in which a single village resides in a location that permits easy access to closely located ecological zones. Different crop zones or pasturelands are located within a few days walk of the parent community. Community members may reside temporarily in one of the lower zones to manage the extraction of products unavailable in the homeland. In the second variation, called the "vertical archipelago," the village exploits resources in widely dispersed locations, constituting a series of independent production "islands." In certain pre-Columbian Inca societies, groups were sent from the home territory to establish permanent satellite communities or colonies in distant tropical forests or coastal locations. There the colonists grew crops and extracted products for their wn use and for transshipment back to their high-altitude compatriots. In contrast to the compressed verticality system, in this system, ommodities rather than people circulated through the archipelago.

题目：

According to the passage, the inhabitants of the Andean highlands resolved the problem of unequal resource distribution primarily in which of the following ways?

选项:

A、Following self-sufficient agricultural practices
B、Increasing commodity production from the ecological zones in the highland basins
C、Increasing their reliance on long-distance trade networks
D、Establishing satellite communities throughout the Andean highlands
E、Establishing production forces in ecological zones beyond their parent communities

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.
