文章:

Ethnohistoric documents from sixteenth-century Mexico suggesting that weaving and cooking were the most common productive activities for Aztec women may lead modern historians to underestimate the value of women's contributions to Aztec society.  Since weaving and cooking occurred mostly (but not entirely) in a domestic setting, modern historians are likely to apply to the Aztec culture the modern Western distinction between "private" and "public" production.  Thus, the ethnohistoric record conspires with Western culture to foster the view that women's production was not central to the demographic, economic, and political structures in sixteenth-century Mexico.
 
A closer examination of Aztec culture indicates that treating Aztec women's production in Mexico in such a manner would be a mistake.  Even if the products of women's labor did not circulate beyond the household, such products were essential to population growth.  Researchers document a tenfold increase in the population of the valley of Mexico during the previous four centuries, an increase that was crucial to the developing Aztec political economy.  Population growth--which could not have occurred in the absence of successful household economy, in which women's work was essential--made possible the large-scale development of labor-intensive chinampa (ridged-field) agriculture in the southern valley of Mexico which, in turn, supported urbanization and political centralization in the Aztec capital.
 
But the products of women's labor did in fact circulate beyond the household.  Aztec women wove cloth, and cloth circulated through the market system, the tribute system, and the redistributive economy of the palaces.  Cotton mantles served as a unit of currency in the regional market system.  Quantities of woven mantles, loincloths, blouses, and skirts were paid as tribute to local lords and to imperial tax stewards and were distributed to ritual and administrative personnel, craft specialists, warriors, and other faithful servants of the state.  In addition, woven articles of clothing served as markers of social status and clothing fulfilled a symbolic function in political negotiation.  The cloth that was the product of women's work thus was crucial as a primary means of organizing the flow of goods and services that sustained the Aztec state.

题目:

Ozone in the stratosphere blocks deadly ultraviolet rays from the sun, but chlorofluorocarbons (CFCs) in aerosols and other products have thinned this protective layer. Evidence of this is the ozone hole that forms over the South Pole every Antarctic spring as temperatures drop below –78°C, the temperature at which ozone depletion occurs. Measurements of the ozone hole taken at various times this spring show that, compared with the same times the previous year, its area diminished by four million square kilometers. Nevertheless, scientists have not concluded that the ozone layer is recovering.

Which of the following would, if true, provide the strongest reason for the scientists’ reaction to the measurements?

选项:

A、The ozone hole has steadily grown in size every year for the past decade except this year.
B、The length of time that the ozone hole persists fluctuates from year to year.
C、As a result of international treaties, CFCs have been completely banned for several years.
D、Weather patterns allowed unusual amounts of warm air to mix into the polar regions this year.
E、Human-made CFCs retain their ability to destroy ozone molecules for seventy-five to one hundred years.

文章:

Early in the twentieth century, Lake Konfa became very polluted. Recently fish populations have recovered as release of industrial pollutants has declined and the lake's waters have become cleaner. Fears are now being voiced that the planned construction of an oil pipeline across the lake's bottom might revive pollution and cause the fish population to decline again. However, a technology for preventing leaks is being installed. Therefore, provided this technology is effective, the fears are groundless.

题目:

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

选项:

A、The pipeline's construction will disturb sediments at the bottom of the lake, dispersing into the water toxic pollutants that have settled there. Changes in land use and drainage patterns around the lake mean that the lake's waters are increasingly likely to be affected by agricultural runoff.
B、The leak-preventing technology has been in use for several years without any pipeline in which it is installed developing serious leaks.
C、A major leak of oil from the pipeline would harm not only the lake's fish but also populations of other aquatic animals and plants. 
D、Since the beginning of the twentieth century, non-native species of fish have been introduced into the lake and now make up a considerable proportion of its overall fish population.

文章:

Line Critics maintain that the fiction of Herman Melville
(1819–1891) has limitations, such as its lack
of inventive plots after Moby-Dick (1851) and its
occasionally inscrutable style. A more serious, yet
(5) problematic, charge is that Melville is a deficient
writer because he is not a practitioner of the “art of
fiction,” as critics have conceived of this art since the
late nineteenth-century essays and novels of Henry
James. Indeed, most twentieth-century commentators
(10) regard Melville not as a novelist but as a writer of
romance, since they believe that Melville’s fiction
lacks the continuity that James viewed as essential
to a novel: the continuity between what characters
feel or think and what they do, and the continuity
(15) between characters’ fates and their pasts or original
social classes. Critics argue that only Pierre (1852),
because of its subject and its characters, is close to
being a novel in the Jamesian sense.
However, although Melville is not a Jamesian
(20) novelist, he is not therefore a deficient writer. A more
reasonable position is that Melville is a different
kind of writer, who held, and should be judged
by, presuppositions about fiction that are quite
different from James’s. It is true that Melville wrote
(25) “romances”; however, these are not the escapist
fictions this word often implies, but fictions that
range freely among very unusual or intense human
experiences. Melville portrayed such experiences
because he believed these best enabled him to
(30) explore moral questions, an exploration he assumed
was the ultimate purpose of fiction. He was content
to sacrifice continuity or even credibility as long
as he could establish a significant moral situation.
Thus Melville’s romances do not give the reader
(35) a full understanding of the complete feelings and
thoughts that motivate actions and events that shape
fate. Rather, the romances leave unexplained the
sequence of events and either simplify or obscure
motives. Again, such simplifications and obscurities
(40) exist in order to give prominence to the depiction of
sharply delineated moral values, values derived from
a character’s purely personal sense of honor, rather
than, as in a Jamesian novel, from the conventions of
society.

选项:

A、make a case for the importance of skillful psychological motivation in well-written novels and romances
B、contrast the romantic and novelistic traditions and assert the aesthetic superiority of the romantic tradition

D、argue that the charges made against Melville’s fiction by literary critics are suspect and misleading

文章:

    In 1938, at the government-convened National Health Conference, organized labor emerged as a major proponent of legislation to guarantee universal health care in the United States. The American Medical Association, representing physicians' interests, argued for preserving physicians' free-market prerogatives. Labor activists countered these arguments by insisting that health care was a fundamental right that should be guaranteed by government programs.

    The labor activists' position represented a departure from the voluntarist view held until 1935 by leaders of the American Federation of labor (AFL), a leading affiliation of labor unions; the voluntarist view stressed workers' right to freedom from government intrusions into their lives and represented national health insurance as a threat to workers' privacy. AFL president Samuel Gompers, presuming to speak for all workers, had positioned the AFL as a leading opponent of the proposals for national health insurance that were advocated beginning in 1915 by the American Association for Labor Legislation (AALL), an organization dedicated to the study and reform of labor laws. Gompers' opposition to national health insurance was partly principled, arising from the premise that governments under capitalism invariably served employers', not workers', interests. Gompers feared the probing of government bureaucrats into workers' lives, as well as the possibility that government-mandated health insurance, financed in part by employers, could permit companies to require employee medical examinations that might be used to discharge disabled workers.

    Yet the AFL's voluntarism had accommodated certain exceptions: the AFL had supported government intervention on behalf of injured workers and child laborers. AFL officials drew the line at national health insurance, however, partly out of concern for their own power. The fact that AFL outsiders such as the AALL had taken the most prominent advocacy roles antagonized Gompers. That this reform threatened unionsponsored benefit programs championed by Gompers made national health insurance even more objectionable. Indeed, the AFL leadership did face serious organizational divisions. Many unionists, recognizing that union-run health programs covered only a small fraction of union members and that unions represented only a fraction of the nation's workforce, worked to enact compulsory health insurance in their state legislatures. This activism and the views underlying it came to prevail in the United States labor movement and in 1935 the AFL unequivocally reversed its position on health legislation.

题目:

The passage suggests which of the following about the voluntarist view held by leaders of the AFL regarding health care?

选项:

A、It was opposed by the AALL.
B、It was shared by most unionists until 1935.
C、It antagonized the American Medical Association.
D、It maintained that employer-sponsored health care was preferable to union-run health programs.
E、It was based on the premise that the government should protect child laborers but not adult workers.

A

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.
