文章:

    When the history of women began to receive focused attention in the 1970', Eleanor Roosevelt was one of a handful of female Americans who were well known to both historians and the general public. Despite the evidence that she had been important in socialreform circles before her husband was elected President and that she continued to advocate different causes than he did, she held a place in the public imagination largely because she was the wife of a particularly influential President. Her own activities were seen as preparing the way for her husband's election or as a complement to his programs. Even Joseph Lash's two volumes of Sympathetic biography, Eleanor and Franklin (1971) and Eleanor: The Years Alone (1972), reflected this assumption.

    Lash's biography revealed a Complicated woman who sought Through political activity both to flee inner misery and to promote causes in which she passionately believed. However, she still appeared to be an idiosyncratic figure, somehow self-generated not amenable to any generalized explanation. She emerged from the biography as a mother to the entire nation, or as a busybody. but hardly as a social type, a figure comprehensible in terms of broader social developments.

    But more recent work on the feminism of the post-suffrage years (following 1920) allows us to see Roosevelt in a different light and to bring her life into a more richly detailed context. Lois Scharf's Eleanor Roosevelt, written In 1987, depicts a generation of Privileged women, born in the late Nineteenth century and maturing in the twentieth, who made the transition from old patterns of female association to new ones. Their views and their lives were full Of contradictions. They maintained female social networks but began to integrate women into mainstream politics; they demanded equal treatment but also argued that women's maternal responsibilities made them both wards and representatives of the public interest. Thanks to Scharf and others, Roosevelt's activities—for example, her support both for labor laws protecting women and for appointments of women to high public office—have become intelligible in terms of this social context rather than as the idiosyncratic career of a famous man's wife.

题目:

The author cites which of the following as evidence against the public view of Eleanor Roosevelt held in the 1970's?

选项:

A、She had been born into a wealthy family.
B、Her political career predated the adoption of women's suffrage.
C、She continued her career in politics even After her husband's death.
D、She was one of a few female historical Figures who were well known to historians By the 1970's.
E、Her activism predated her husband's presidency and her projects differed from his.

文章:

    In 1994, a team of scientists led by David Mckay began studying the meteorite ALH84001, which had been discovered in Antarctica in 1984. Two years later, the McKay team announced that ALH84001, which scientists generally agree originated on Mars, contained compelling evidence that life once existed on Mars. This evidence includes the discovery of organic molecules in ALH84001,the first ever found in Martian rock. Organic molecules-complex, carbon based compounds-form the basis for terrestrial life. The organic molecules found in ALH84001 are polycyclic aromatic hydrocarbons, or PAH's. When microbes die, their organic material often decays into PAH's.

    Skepticism about the McKay team's claim remains, however. For example,ALH84001 has been on earth for 13,000 years, suggesting to some scientists that its PAH's might have resulted from terrestrial contamination. However, McKay's team has demonstrated that the concentration of PAH's increases as one looks deeper into ALH84001, contrary to what one would expect from terrestrial contamination. The skeptic's strongest argument, however, is that processes unrelated to organic life can easily produce all the evidence found by McKay' steam, including PAH's. For example, star formation produces PAH's. Moreover, PAH's frequently appear in other meteorites, and no one attributes their presence to life processes. Yet McKay's team notes that the particular combination of PAH's in ALH84001 is more similar to the combinations produced by decaying organisms than to those originating form nonbiological processes.

文章:

Line        Resin is a plant secretion that hardens when
 exposed to air; fossilized resin is called amber.
 Although Pliny in the first century recognized that
 amber was produced from “marrow discharged by
(5)trees,” amber has been widely misunderstood to be
 a semiprecious gem and has even been described
 in mineralogy textbooks. Confusion also persists
 surrounding the term “resin,” which was defined
 before rigorous chemical analyses were available.
(10)Resin is often confused with gum, a substance
 produced in plants in response to bacterial infections,
 and with sap, an aqueous solution transported
 through certain plant tissues. Resin differs from both
 gum and sap in that scientists have not determined a
(15)physiological function for resin.
      In the 1950s, entomologists posited that resin
 may function to repel or attract insects. Fraenkel
 conjectured that plants initially produced resin in
 nonspecific chemical responses to insect attack
(20)and that, over time, plants evolved that produced
 resin with specific repellent effects. But some insect
 species, he noted, might overcome the repellent
 effects, actually becoming attracted to the resin.
 This might induce the insects to feed on those
(25)plants or aid them in securing a breeding site.
 Later researchers suggested that resin mediates
 the complex interdependence, or “coevolution,” of
 plants and insects over time. Such ideas led to the
 development of the specialized discipline of chemical
(30)ecology, which is concerned with the role of plant
 chemicals in interactions with other organisms and
 with the evolution and ecology of plant antiherbivore
 chemistry (plants' chemical defenses against attack
 by herbivores such as insects).

The author of the passage refers to Pliny most probably in order to

选项:

A、now at a lower rate than

文章:

Conventional wisdom has it that large deficits in the United States budget cause interest rates to rise.  Two main arguments are given for this claim.  According to the first, as the deficit increases, the government will borrow more to make up for the ensuing shortage of funds.  Consequently, it is argued, if both the total supply of credit (money available for borrowing) and the amount of credit sought by nongovernment borrowers remain relatively stable, as is often supposed, then the price of credit (the interest rate) will increase.  That this is so is suggested by the basic economic principle that if supplies of a commodity (here, credit) remain fixed and demand for that commodity increases, its price will also increase.  The second argument supposes that the government will tend to finance its deficits by increasing the money supply with insufficient regard for whether there is enough room for economic growth to enable such an increase to occur without causing inflation.  It is then argued that financiers will expect the deficit to cause inflation and will raise interest rates, anticipating that because of inflation the money they lend will be worth less when paid back.
 
Unfortunately for the first argument, it is unreasonable to assume that nongovernment borrowing and the supply of credit will remain relatively stable.  Nongovernment borrowing sometimes decreases.  When it does, increased government borrowing will not necessarily push up the total demand for credit.  Alternatively, when credit availability increases, for example through greater foreign lending to the United States, then interest rates need not rise, even if both private and government borrowing increase.
 
The second argument is also problematic.  Financing the deficit by increasing the money supply should cause inflation only when there is not enough room for economic growth.  Currently, there is no reason to expect deficits to cause inflation.  However, since many financiers believe that deficits ordinarily create inflation, then admittedly they will be inclined to raise interest rates to offset mistakenly anticipated inflation.  This effect, however, is due to ignorance, not to the deficit itself, and could be lessened by educating financiers on this issue.

题目:

It can be inferred from the passage that proponents of the second argument would most likely agree with which of the following statements?

选项:

A、The United States government does not usually care whether or not inflation increases.
B、People in the United States government generally know very little about economics.
C、The United States government is sometimes careless in formulating its economic policies.
D、The United States government sometimes relies too much on the easy availability of foreign credit.
E、The United States government increases the money supply whenever there is enough room for growth to support the increase.

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.
