文章:

  Colonial historian David Allen's intensive study of five communities in seventeenth-century Massachusetts is a model of meticulous scholarship on the detailed microcosmic level, and is convincing up to a point. Allen suggests that much more coherence and direct continuity existed between English and colonial agricultural practices and administrative organization than other historians have suggested. However, he overstates his case with the declaration that he has proved ''the remarkable extent to which diversity in New England local institutions was directly imitative of regional differences in the mother country."
  Such an assertion ignores critical differences between seventeenth-century England and New England. First, England was overcrowded and land-hungry; New England was sparsely populated and labor-hungry. Second, England suffered the normal European rate of mortality; New England, especially in the first generation of English colonists, was virtually free from infectious diseases. Third, England had an all-embracing state church; in New England membership in a church was restricted to the elect. Fourth, a high proportion of English villagers lived under paternalistic resident squires; no such class existed in New England. By narrowing his focus to village institutions and ignoring these critical differences, which studies by Greven, Demos, and Lockridge have shown to be so important, Allen has created a somewhat distorted picture of reality.
  Allen's work is a rather extreme example of the ''country community" school of seventeenth-century English history whose intemperate excesses in removing all national issues from the history of that period have been exposed by Professor Clive Holmes. What conclusion can be drawn, for example, from Allen's discovery that Puritan clergy who had come to the colonies from East Anglia were one-third to one-half as likely to return to England by 1660 as were Puritan ministers from western and northern England? We are not told in what way, if at all, this discovery illuminates historical understanding. Studies of local history have enormously expanded our horizons, but it is a mistake for their authors to conclude that village institutions are all that mattered, simply because their functions are all that the records of village institutions reveal.

题目:

The passage suggests that Professor Clive Holmes would most likely agree with which of the following statements?

选项:

A、An understanding of seventeenth-century English local institutions requires a consideration of national issues.
B、The ''country community" school of seventeenth- century English history distorts historical evidence in order to establish continuity between old and new institutions.
C、Most historians distort reality by focusing on national concerns to the exclusion of local concerns.
D、National issues are best understood from the perspective of those at the local level.
E、Local histories of seventeenth-century English villages have contributed little to the understanding of village life.

题目:

As a construction material, bamboo is as strong as steel and sturdier than concrete. Moreover, in tropical areas bamboo is a much less expensive construction material than either steel or concrete and is always readily available. In tropical areas, therefore, building with bamboo makes better economic sense than building with steel or concrete, except where land values are high.

Which of the following, if true, most helps to explain the exception noted above?

选项:

A、Buildings constructed of bamboo are less likely to suffer earthquake damage than are steel and concrete buildings.
B、Bamboo is unsuitable as a building material for multistory buildings.
C、In order to protect it from being damaged by termites and beetles, bamboo must be soaked, at some expense, in a preservative.
D、In some tropical areas, bamboo is used to make the scaffolding that is used during large construction projects.
E、Bamboo growing in an area where land values are increasing is often cleared to make way for construction.

文章:

In order to withstand tidal currents, juvenile horseshoe crabs frequently burrow in the sand. Such burrowing discourages barnacles from clinging to their shells. When fully grown, however, the crabs can readily withstand tidal currents without burrowing, and thus they acquire substantial populations of barnacles. Surprisingly, in areas where tidal currents are very weak, juvenile horseshoe crabs are found not to have signifi cant barnacle populations, even though they seldom burrow.

题目:

Which of the following, if true, most helps to explain the surprising fi nding?

选项:

A、Tidal currents do not themselves dislodge barnacles from the shells of horseshoe crabs.Barnacles most readily attach themselves to horseshoe crabs in areas where tidal currents are weakest
B、The strength of the tidal currents in a given location varies widely over the course of a day. 
C、A very large barnacle population can signifi cantly decrease the ability of a horseshoe crab to fi nd food
D、Until they are fully grown, horseshoe crabs shed their shells and grow new ones several times a year.

文章:

    A key decision required of advertising managers is whether a "hard-sell" or "soft-sell" strategy is appropriate for a specific target market. The hard-sell approach involves the use of direct, forceful claims regarding the benefits of the advertised brand over competitors' offerings. In contrast, the soft-sell approach involves the use of advertising claims that imply superiority more subtly

    One positive aspect of the hard-sell approach is its use of very simple and straightforward product claims presented claims presented as explicit conclusions, with little room for confusion regarding the advertiser's message. However, some consumers may resent being told what to believe and some may distrust the message. Resentment and distrust often lead to counterargumentation and to boomerang effects where consumers come to believe conclusions diametrically opposed to conclusions endorsed in adverrising claims, By contrast, the risk of boomerang erects is greatly reduced with soft-sell approaches. One way to implement the soft-sell approach is to provide information that implies the main conclusions the advertiser wants the consumer to draw, but leave the conclusions themselves unstated. Because consumers are invited to make up their own minds, implicit conclusions reduce the risk of resentment ,distrust, and counter argumentation.

    Recent research on consumer memory and judgment suggests another advantage of implicit conclusions. Beliefs or conclusions that are self-generated are more accessible from memory than beliefs from conclusions provided explicitly by other individuals, and thus have a greater impact on judgment and decision making. Moreover, self-generated beliefs are often perceived as more accurate and valid than the beliefs of others, because other individuals may be perceived as less less knowledgeable, or may be perceived as manipulative or deliberately misleading. Despite these advantages, implicit conclusions may mot always be more effective than explicit Conclusions. One risk is that some consumers may fail to draw their own conclusions and thus miss the point of the message. .Inferential activity is likely only when consumers are motivated and able to engage in effortful cognitive processes. Another risk is that some conSummers may draw conclusions Other than the one intended ,Even if inferential activity is likely there is no guarantee that consumers will follow the path provided by the advertiser. Finally, a third risk is that consumers may infer the intended conclusion but question the validity of their inference.

题目:

it can be inferred from the passage that advertisers could reduce one of the risks discussed in the last paragraph if they were able to provide

选项:

A、motivation for consumers to think about the advertisement's message 
B、information that implies the advertiser's intended conclusion but leaves that conclusion unstated
C、subtle evidence that the advertised product is superior to that of competitors
D、information comparing the advertised prod uct with its competitors
E、opportunity for consumers to generate their own beliefs or conclusions

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.
