题目：

Hollywood restaurant is replacing some of its standard tables with tall tables and stools. The restaurant already fills every available seat during its operating hours, and the change in seating arrangements will not result in an increase in the restaurant’s seating capacity. Nonetheless, the restaurant’s management expects revenue to increase as a result of the seating change without any concurrent change in menu, prices, or operating hours.

Which of the following, if true, provides the best reason for the expectation?

选项:

A、One of the taller tables takes up less floor space than one of the standard tables.
B、Diners seated on stools typically do not linger over dinner as long as diners seated at standard tables.
C、Since the restaurant will replace only some of its standard tables, it can continue to accommodate customers who do not care for the taller tables.
D、Few diners are likely to avoid the restaurant because of the new seating arrangement.
E、The standard tables being replaced by tall tables would otherwise have to be replaced with new standard tables at a greater expense.

答案:

B

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：

Which of the following statements about Clark’s study of the telephone exchange can be inferred from information in the passage?

选项:

A、Clark’s reason for undertaking the study was to undermine Braverman’s analysis of the function of technology.
B、Clark’s study suggests that the implementation of technology should be discussed in the context of conflict between labor and management.
C、Clark examined the impact of changes in the technology of switching at the exchange in terms of overall operations and organization.
D、Clark concluded that the implementation of new switching technology was equally beneficial to management and labor.
E、Clark’s analysis of the change in switching systems applies only narrowly to the situation at the particular exchange that he studied.

题目：

Many athletes inhale pure oxygen after exercise in an attempt to increase muscular reabsorption of oxygen. Measured continuously after exercise, however, the blood lactate levels of athletes who inhale pure oxygen are practically identical, on average, to those of athletes who breathe normal air. The lower the blood lactate level is, the higher the muscular reabsorption of oxygen is.

If the statements above are all true, they most strongly support which of the following conclusions?

选项:

A、Athletes’ muscular reabsorption of oxygen is not increased when they inhale pure oxygen instead of normal air.
B、High blood lactate levels cannot be reduced.
C、Blood lactate levels are a poor measure of oxygen reabsorption by muscles.
D、The amount of oxygen reabsorbed by an athlete’s muscles always remains constant.
E、The inhaling of pure oxygen has no legitimate role in athletics.

文章：

Although the industrial union organizations that emerged under the banner of the Congress of Industrial Organizations (CIO) in the 1930s and 1940s embraced the principles of nondiscrimination and inclusion, the role of women within unions reflected the prevailing gender ideology of the period.  Elizabeth Faue's study of the labor movement in Minneapolis argues that women were marginalized by union bureaucratization and by the separation of unions from the community politics from which industrial unionism had emerged.  Faue stresses the importance of women's contribution to the development of unions at the community level, contributions that made women's ultimate fate within the city's labor movement all the more poignant:  as unions reached the peak of their strength in the 1940s, the community base that had made their success possible and to which women's contributions were so vital became increasingly irrelevant to unions' institutional life.
 
In her study of CIO industrial unions from the 1930s to the 1970s, Nancy F. Gabin also acknowledges the pervasive male domination in the unions, but maintains that women workers were able to create a political space within some unions to advance their interests as women.  Gabin shows that, despite the unions' tendency to marginalize women's issues, working women's demands were a constant undercurrent within the union, and she stresses the links between the unions' women activists and the wave of feminism that emerged in the 1960s.

题目：

Which of the following can be inferred regarding the "gender ideology" mentioned in the highlighted text?

选项:

A、It prevented women from making significant contributions to the establishment of industrial unions.
B、It resulted from the marginalization of women in industrial unions.
C、It had a significant effect on the advancement of women's issues within industrial unions.
D、Its primary tenets were nondiscrimination and inclusion.
E、Its effects were mitigated by the growth of industrial unions.

(This passage was excerpted from materialpublished in 1993.)

    Like many other industries, the travel industry is under increasing pressure to expand globally in order to keep pace with its corporate customers, who have globalized their operations in response to market pressure, competitor actions, and changing supplier relations. But it is difficult for service organizations to globalize. Global expansion through acquisition is usually expensive, and expansion through internal growth is time-consuming and sometimes impossible in markets that are not actively growing. Some service industry companies, in fact, regard these traditional routes to global expansion as inappropriate for service industries because of their special need to preserve local responsiveness through local presence and expertise. One travel agency has eschewed the traditional route altogether. A survivor of the changes that swept the travel industry as a result of the deregulation of the airlines in 1978—changes that included dramatic growth in the corporate demand for travel services, as well as extensive restructuring and consolidation within the travel industry— this agency adopted a unique structure for globalization. Rather than expand by attempting to develop its own offices abroad, which would require the development of local travel management expertise sufficient to capture foreign markets, the company solved its globalization dilemma effectively by forging alliances with the best foreign partners it could find. The resulting cooperative alliance of independent agencies now comprises 32 partners spanning 37 countries.

题目：

The author discusses a particular travel agency in the passage most likely in order to

选项:

A、provide evidence of the pressures on the travel industry to globalize
B、demonstrate the limitations of the traditional routes to global expansion
C、illustrate an unusual approach to globalizing a service organization
D、highlight the difficulties confronting travel agencies that attempt to globalize
E、underscore the differences between the service industry and other industries

文章：

Dendrochronology, the study of tree-ring records to glean information about the past, is possible because each year a tree adds a new layer of wood between the existing wood and the bark.  In temperate and subpolar climates, cells added at the growing season's start are large and thin-walled, but later the new cells that develop are smaller and thick-walled; the growing season is followed by a period of dormancy.  When a tree trunk is viewed in cross section, a boundary line is normally visible between the small-celled wood added at the end of the growing season in the previous year and the large-celled spring wood of the following year's growing season.  The annual growth pattern appears as a series of larger and larger rings.  In wet years rings are broad; during drought years they are narrow, since the trees grow less.  Often, ring patterns of dead trees of different, but overlapping, ages can be correlated to provide an extended index of past climate conditions.
 
However, trees that grew in areas with a steady supply of groundwater show little variation in ring width from year to year; these "complacent" rings tell nothing about changes in climate.  And trees in extremely dry regions may go a year or two without adding any rings, thereby introducing uncertainties into the count.  Certain species  sometimes add more than one ring in a single year, when growth halts temporarily and then starts again.

题目：

In the highlighted text, "uncertainties" refers to

选项:

A、dendrochronologists' failure to consider the prevalence of erratic weather patterns
B、inconsistencies introduced because of changes in methodology
C、some tree species' tendency to deviate from the norm
D、the lack of detectable variation in trees with complacent rings
E、the lack of perfect correlation between the number of a tree's rings and its age

E

题目：

Senator Janice White is quietly lobbying to become chairman of one of the Senate’s most prestigious committees. However, that post currently belongs to Senator Dan Smith. If Senator Smith already has twenty senators committed to his continued chairmanship of the committee, then Senator White will consider another committee. If Senator Smith does not have that much support lined up yet, then Senator White will study Senator Smith’s past committee voting record for inconsistent and unpopular votes. If Senator White finds that Smith’s voting record is out of favor with today’s voter and publicizes it, then her chances of capturing the chairmanship would be increased, and she would publicly announce her interest in the chairmanship. If Senator Smith’s committee voting record is in keeping with current public sentiment and contains no inconsistencies, then Senator White will focus her attention on another committee chairmanship.
Based upon the information provided in the passage, which one of the following statements must be false?

选项:

A、A. Senator Smith has lined up only five votes, and Senator White drops her interest in the committee chairmanship.
B、B. A number of inconsistencies are found in Senator Smith's voting record, and Senator White publicly announces her interest in the committee chairmanship.
C、C. Several of Senator Smith's past committee votes would find disfavor with today's voting public, and Senator White does not pursue the committee chairmanship.
D、D. Senator Smith's past committee voting record contains nothing that would increase Senator White's chances of obtaining the chairmanship, and Senator White publicly announces her interest in being named chairman.
E、E. Senator Smith already has the support of thirty of his fellow senators, and Senator White focuses her interest on another committee.

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.
