文章：
| Line | Jon Clark’s study of the effect of the modernization |
| of a telephone exchange on exchange maintenance | |
| work and workers is a solid contribution to a debate | |
| that encompasses two lively issues in the history and | |
| (5) | sociology of technology: technological determinism |
| and social constructivism. | |
| Clark makes the point that the characteristics of a | |
| technology have a decisive influence on job skills and | |
| work organization. Put more strongly, technology can | |
| (10) | be a primary determinant of social and managerial |
| organization. Clark believes this possibility has | |
| been obscured by the recent sociological fashion, | |
| exemplified by Braverman’s analysis, that emphasizes | |
| the way machinery reflects social choices. For | |
| (15) | Braverman, the shape of a technological system is |
| subordinate to the manager’s desire to wrest control | |
| of the labor process from the workers. Technological | |
| change is construed as the outcome of negotiations | |
| among interested parties who seek to incorporate | |
| (20) | their own interests into the design and configuration |
| of the machinery. This position represents the new | |
| mainstream called social constructivism. | |
| The constructivists gain acceptance by | |
| misrepresenting technological determinism: | |
| (25) | technological determinists are supposed to believe, |
| for example, that machinery imposes appropriate | |
| forms of order on society. The alternative to | |
| constructivism, in other words, is to view technology | |
| as existing outside society, capable of directly | |
| (30) | influencing skills and work organization. |
| Clark refutes the extremes of the constructivists | |
| by both theoretical and empirical arguments. | |
| Theoretically he defines “technology” in terms of | |
| relationships between social and technical variables. | |
| (35) | Attempts to reduce the meaning of technology to |
| cold, hard metal are bound to fail, for machinery is | |
| just scrap unless it is organized functionally and | |
| supported by appropriate systems of operation and | |
| maintenance. At the empirical level Clark shows how | |
| (40) | a change at the telephone exchange from |
| maintenance-intensive electromechanical switches | |
| to semielectronic switching systems altered work | |
| tasks, skills, training opportunities, administration, | |
| and organization of workers. Some changes Clark | |
| (45) | attributes to the particular way management and |
| labor unions negotiated the introduction of the | |
| technology, whereas others are seen as arising from | |
| the capabilities and nature of the technology itself. | |
| Thus Clark helps answer the question: “When is | |
| (50) | social choice decisive and when are the concrete |
| characteristics of technology more important?” |
题目：
The author of the passage uses the expression “are supposed to” in line 25 primarily in order to
选项:
A、suggest that a contention made by constructivists regarding determinists is inaccurate
B、define the generally accepted position of determinists regarding the implementation of technology
C、engage in speculation about the motivation of determinists
D、lend support to a comment critical of the position of determinists
E、contrast the historical position of determinists with their position regarding the exchange modernization

| Line | In 1955 Maurice Duverger published The Political |
| Role of Women, the first behavioralist, multinational | |
| comparison of women’s electoral participation ever to | |
| use election data and survey data together. | |
| (5) | His study analyzed women’s patterns of voting, |
| political candidacy, and political activism in four | |
| European countries during the first half of the | |
| twentieth century. Duverger’s research findings | |
| were that women voted somewhat less frequently | |
| (10) | than men (the difference narrowing the longer |
| women had the vote) and were slightly more | |
| conservative. | |
| Duverger’s work set an early standard for the | |
| sensitive analysis of women’s electoral activities. | |
| (15) | Moreover, to Duverger’s credit, he placed his |
| findings in the context of many of the historical | |
| processes that had shaped these activities. | |
| However, since these contexts have changed over | |
| time, Duverger’s approach has proved more durable | |
| (20) | than his actual findings. In addition, Duverger’s |
| discussion of his findings was hampered by his failure | |
| to consider certain specific factors important to | |
| women’s electoral participation at the time he | |
| collected his data: the influence of political regimes, | |
| (25) | the effects of economic factors, and the |
| ramifications of political and social relations between | |
| women and men. Given this failure, Duverger’s | |
| study foreshadowed the enduring limitations of the | |
| behavioralist approach to the multinational study of | |
| (30) | women’s political participation. |

| Line | Milankovitch proposed in the early twentieth |
| century that the ice ages were caused by variations | |
| in the Earth’s orbit around the Sun. For some time | |
| this theory was considered untestable, largely | |
| (5) | because there was no sufficiently precise |
| chronology of the ice ages with which the orbital | |
| variations could be matched. | |
| To establish such a chronology it is necessary to | |
| determine the relative amounts of land ice that | |
| (10) | existed at various times in the Earth’s past. A |
| recent discovery makes such a determination | |
| possible: relative land-ice volume for a given period | |
| can be deduced from the ratio of two oxygen | |
| isotopes, 16 and 18, found in ocean sediments. | |
| (15) | Almost all the oxygen in water is oxygen 16, but a |
| few molecules out of every thousand incorporate the | |
| heavier isotope 18. When an ice age begins, the | |
| continental ice sheets grow, steadily reducing the | |
| amount of water evaporated from the ocean that | |
| (20) | will eventually return to it. Because heavier |
| isotopes tend to be left behind when water | |
| evaporates from the ocean surfaces, the remaining | |
| ocean water becomes progressively enriched in | |
| oxygen 18. The degree of enrichment can be | |
| (25) | determined by analyzing ocean sediments of the |
| period, because these sediments are composed of | |
| calcium carbonate shells of marine organisms, | |
| shells that were constructed with oxygen atoms | |
| drawn from the surrounding ocean. The higher the | |
| (30) | ratio of oxygen 18 to oxygen 16 in a sedimentary |
| specimen, the more land ice there was when the | |
| sediment was laid down. | |
| As an indicator of shifts in the Earth’s climate, | |
| the isotope record has two advantages. First, it is a | |
| (35) | global record: there is remarkably little variation in |
| isotope ratios in sedimentary specimens taken from | |
| different continental locations. Second, it is a | |
| more continuous record than that taken from rocks | |
| on land. Because of these advantages, sedimentary | |
| (40) | evidence can be dated with sufficient accuracy |
| by radiometric methods to establish a precise | |
| chronology of the ice ages. The dated isotope | |
| record shows that the fluctuations in global ice | |
| volume over the past several hundred thousand | |
| (45) | years have a pattern: an ice age occurs roughly once |
| every 100,000 years. These data have established | |
| a strong connection between variations in the Earth’s | |
| orbit and the periodicity of the ice ages. | |
| However, it is important to note that other | |
| (50) | factors, such as volcanic particulates or variations |
| in the amount of sunlight received by the Earth, | |
| could potentially have affected the climate. The | |
| advantage of the Milankovitch theory is that it | |
| is testable; changes in the Earth’s orbit can be | |
| (55) | calculated and dated by applying Newton’s laws of |
| gravity to progressively earlier configurations of the | |
| bodies in the solar system. Yet the lack of | |
| information about other possible factors affecting | |
| global climate does not make them unimportant. |
题目：

选项:
A、are not as susceptible to deterioration as rocks
B、are less common in sediments formed during an ice age

E

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 .

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.
Which of the following, if discovered in experiments using artificially moved prey insects, would support one of the two hypotheses and undermine the other?
