文章：

Line    Women’s grassroots activism and their vision
  of a new civic consciousness lay at the heart of
  social reform in the United States throughout the
  Progressive Era, the period between the depression
(5) of 1893 and America’s entry into the Second
  World War. Though largely disenfranchised except
  for school elections, white middle-class women
  reformers won a variety of victories, notably in
  the improvement of working conditions, especially
(10) for women and children. Ironically, though,
  child labor legislation pitted women of different
  classes against one another. To the reformers,
  child labor and industrial home work were equally
  inhumane practices that should be outlawed, but,
(15) as a number of women historians have recently
  observed, working-class mothers did not always
  share this view. Given the precarious finances of
  working-class families and the necessity of pooling
  the wages of as many family members as possible,
(20) working-class families viewed the passage and
  enforcement of stringent child labor statutes as a
  personal economic disaster and made strenuous
  efforts to circumvent child labor laws. Yet
  reformers rarely understood this resistance in terms
(25) of the desperate economic situation of working-
  class families, interpreting it instead as evidence
  of poor parenting. This is not to dispute women
  reformers’ perception of child labor as a terribly
  exploitative practice, but their understanding of
(30) child labor and their legislative solutions for ending
  it failed to take account of the economic needs of
  working-class families.


题目：

The author of the passage mentions the observations of women historians (lines 15–17) most probably in order to

选项:

A、provide support for an assertion made in the preceding sentence (lines 10–12)
B、raise a question that is answered in the last sentence of the passage (lines 27–32)
C、introduce an opinion that challenges a statement made in the first sentence of the passage
D、offer an alternative view to the one attributed in the passage to working-class mothers
E、point out a contradiction inherent in the traditional view of child labor reform as it is presented in the passage

题目：

Fact 2: The overall rate of acceptance of domestic films was significantly higher than that of foreign films.

In light of the background information, which of the following, if true, can account for fact 1 and fact 2 both being true of the submissions to this year's Barbizon Film Festival?

选项:

A、In each category, the selection panel was composed of filmmakers, and some selection panels included no foreign filmmakers.
B、Significantly more domestic films than foreign films were submitted to the festival.
C、In each of the past three years, the overall acceptance rate was higher for foreign than for domestic films, an outcome that had upset some domestic filmmakers.
D、The number of films to be selected in each category was predetermined, but in no category was it required that the acceptance rate of foreign films should equal that of domestic films.
E、Most foreign films, unlike most domestic films, were submitted in categories with high prestige, but with correspondingly low rates of acceptance.

题目：

Newspaper editors should not allow reporters to write the headlines for their own stories. The reason for this is that, while the headlines that reporters themselves write are often clever, what typically makes them clever is that they allude to little-known information that is familiar to the reporter but that never appears explicitly in the story itself.

Which of the following, if true, most strengthens the argument?

选项:

A、The reporter who writes a story is usually better placed than the reporter's editor is to judge what the story's most newsworthy features are.
B、To write a headline that is clever, a person must have sufficient understanding of the story that the headline accompanies.
C、Most reporters rarely bother to find out how other reporters have written stories and headlines about the same events that they themselves have covered.
D、For virtually any story that a reporter writes, there are at least a few people who know more about the story's subject matter than does the reporter.
E、The kind of headlines that newspaper editors want are those that anyone who has read a reporter's story in its entirety will recognize as clever.

文章：

According to P. F. Drucker, the management philosophy known as Total Quality Management (TQM), which is designed to be adopted consistently throughout an organization and to improve customer service by using sampling theory to reduce the variability of a product's quality, can work successfully in conjunction with two older management systems.  As Drucker notes, TQM's scientific approach is consistent with the statistical sampling techniques of the "rationalist" school of scientific management, and the organizational structure associated with TQM is consistent with the social and psychological emphases of the "human relations" school of management.
 
However, TQM cannot simply be grafted onto these systems or onto certain other non-TQM management systems.  Although, as Drucker contends, TQM shares with such systems the ultimate objective of increasing profitability, TQM requires fundamentally different strategies.  While the other management systems referred to use upper management decision-making and employee specialization to maximize shareholder profits over the short term, TQM envisions the interests of employees, shareholders, and customers as convergent.  For example, lower prices not only benefit consumers but also enhance an organization's competitive edge and ensure its continuance, thus benefiting employees and owners.  TQM's emphasis on shared interests is reflected in the decentralized decision-making, integrated production activity, and lateral structure of organizations that achieve the benefits of TQM.

题目：

According to the passage, the rationalist and human relations schools of management are alike in that they

选项:

A、 are primarily interested in increasing profits
B、 place little emphasis on issues of organizational structure
C、 use statistical sampling techniques to increase profitability
D、 are unlikely to lower prices in order to increase profitability
E、 focus chiefly on setting and attaining long-term objectives

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