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.

答案:

B

Certain messenger molecules fight damage to the lungs from noxious air by telling the muscle cells encircling the lungs'airways to contract.This partially seals off the lungs.An asthma attack occurs when the messenger molecules are activated unnecessarily, in response to harmless things like pollen or household dust.

题目:

Which of the following, if true, points to the most serious flaw of a plan to develop a medication that would prevent asthma attacks by blocking receipt of any messages sent by the messenger molecules referred to above?

选项:

A、Researchers do not yet know how the body produces the messenger molecules that trigger asthma attacks.Researchers do not yet know what makes one person's messenger molecules more easily activated than another's. 
B、Such a medication would not become available for several years, because of long lead times in both development and manufacture.
C、Such a medication would be unable to distinguish between messages triggered by pollen and household dust and messages triggered by noxious air. 
D、Such a medication would be a preventative only and would be unable to alleviate an asthma attack once it had started.

文章:

Lyme disease is caused by a bacterium transmitted to humans by deer ticks. Generally, deer ticks pick up the bacterium while in the larval stage by feeding on infected white-footed mice. However, certain other species on which the larvae feed do not harbor the bacterium. If the population of these other species were increased, more of the larvae would be feeding on uninfected hosts, so the number of ticks acquiring the bacterium would likely decline.

题目:

Which of the following would it be most important to ascertain in evaluating the argument?

选项:

A、Whether populations of the other species on which deer tick larvae feed are found only in areas also inhabited by white-footed miceWhether the size of the deer tick population is currently limited by the availability of animals for the tick's larval stage to feed on
B、Whether the infected deer tick population could be controlled by increasing the number of animals that prey on white-footed mice
C、Whether deer ticks that were not infected as larvae can become infected as adults by feeding on deer on which infected deer ticks have fed
D、Whether the other species on which deer tick larvae feed harbor any other bacteria that ticks transmit to humans

B

文章:

In the two decades between 1910 and 1930, more than ten percent of the black population of the United States left the South, where the preponderance of the black population had been located, and migrated to northern states, with the largest number moving, it is claimed, between 1916 and 1918. It has been frequently assumed, but not proved, that the majority of the migrants in what has come to be called the Great Migration came from rural areas and were motivated by two concurrent factors: the collapse of the cotton industry following the boll weevil infestation, which began in 1898, and increased demand in the North for labor following the cessation of European immigration caused by the outbreak of the First World War in 1914. This assumption has led to the conclusion that the migrants’ subsequent lack of economic mobility in the North is tied to rural background, a background that implies unfamiliarity with urban living and a lack of industrial skills.

But the question of who actually left the South has never been rigorously investigated. Although numerous investigations document an exodus from rural southern areas to southern cities prior to the Great Migration, no one has considered whether the same migrants then moved on to northern cities. In 1910 more than 600,000 black workers, or ten percent of the black workforce, reported themselves to be engaged in "manufacturing and mechanical pursuits," the federal census category roughly encompassing the entire industrial sector. The Great Migration could easily have been made up entirely of this group and their families. It is perhaps surprising to argue that an employed population could be enticed to move, but an explanation lies in the labor conditions then prevalent in the South.

About thirty-five percent of the urban black population in the South was engaged in skilled trades. Some were from the old artisan class of slavery—blacksmiths, masons, carpenters—which had had a monopoly of certain trades, but they were gradually being pushed out by competition, mechanization, and obsolescence. The remaining sixty-five percent, more recently urbanized, worked in newly developed industries—tobacco, lumber, coal and iron manufacture, and railroads. Wages in the South, however, were low, and black workers were aware, through labor recruiters and the black press, that they could earn more even as unskilled workers in the North than they could as artisans in the South. After the boll weevil infestation, urban black workers faced competition from the continuing influx of both black and white rural workers, who were driven to undercut the wages formerly paid for industrial jobs. Thus, a move north would be seen as advantageous to a group that was already urbanized and steadily employed, and the easy conclusion tying their subsequent economic problems in the North to their rural background comes into question.

题目:

It can be inferred from the passage that the "easy conclusion" mentioned in highlight text is based on which of the following assumptions?

选项:

A、People who migrate from rural areas to large cities usually do so for economic reasons.Most people who leave rural areas to take jobs in cities return to rural areas as soon as it is financially possible for them to do so.
B、People with rural backgrounds are less likely to succeed economically in cities than are those with urban backgrounds.
C、Most people who were once skilled workers are not willing to work as unskilled workers.
D、People who migrate from their birthplaces to other regions of a country seldom undertake a second migration.

C

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.
