After the Second World War, unionism in the Japanese auto industry was company-based, with separate unions in each auto company.  Most company unions played no independent role in bargaining shop-floor issues or pressing autoworkers' grievances.  In a 1981 survey, for example, fewer than 1 percent of workers said they sought union assistance for work-related problems, while 43 percent said they turned to management instead.  There was little to distinguish the two in any case: most union officers were foremen or middle-level managers, and the union's role was primarily one of passive support for company goals.  Conflict occasionally disrupted this cooperative relationship--one company union's opposition to the productivity campaigns of the early 1980s has been cited as such a case.  In 1986, however, a caucus led by the Foreman's Association forced the union's leadership out of office and returned the union's policy to one of passive cooperation.  In the United States, the potential for such company unionism grew after 1979, but it had difficulty taking hold in the auto industry, where a single union represented workers from all companies, particularly since federal law prohibited foremen from joining or leading industrial unions.
 
The Japanese model was often invoked as one in which authority decentralized to the shop floor empowered production workers to make key decisions.  What these claims failed to recognize was that the actual delegation of authority was to the foreman, not the workers.  The foreman exercised discretion over job assignments, training, transfers, and promotions; worker initiative was limited to suggestions that fine-tuned a management-controlled production process.  Rather than being proactive, Japanese workers were forced to be reactive, the range of their responsibilities being far wider than their span of control.  For example, the founder of one production system, Taichi Ohno, routinely gave department managers only 90 percent of the resources needed for production.  As soon as workers could meet production goals without working overtime, 10 percent of remaining resources would be removed.  Because the "OH! NO!" system continually pushed the production process to the verge of breakdown in an effort to find the minimum resource requirement, critics described it as "management by stress."

选项:

A、contrasting the role of unions in the Japanese auto industry with the role of unions in the United States auto industry after the Second World War
B、describing unionism and the situation of workers in the Japanese auto industry after the Second World War

题目：

The flowchart represents a mathematical algorithm that takes two positive integers as the input and returns a positive integer as the output. Processes are indicated in the rectangular symbols in the flowchart. Each process is symbolized by an equation, such as T = T + a. In this particular process, the current values of the variables T and a are added together and the sum then becomes the value of T. For example, if the value of T is 3 and the value of a is 7 before the process T = T + a is completed, then the value of T is 10 and the value of a is 7 after the process is completed.

Use the drop-down menus to fill in the blanks in the following statements based on the algorithm represented by the flowchart.

选项:

If 24 and 35 are entered as the values for a and b, respectively, then the first nonzero value of T is .

If 35 and 27 are entered as the values for a and b, respectively, then after the process $$b = rac{b}{2}$$ is completed for the second time, the value of b is .

文章：

Line In current historiography, the picture of a consistent,
unequivocal decline in women’s status with the advent
of capitalism and industrialization is giving way to an
analysis that not only emphasizes both change (whether
(5) improvement or decline) and continuity but also
accounts for geographical and occupational variation.
The history of women’s work in English farmhouse
cheese making between 1800 and 1930 is a case in
point. In her influential Women Workers and the Industrial
(10) Revolution (1930), Pinchbeck argued that the agricultural
revolution of the eighteenth and early nineteenth
centuries, with its attendant specialization and enlarged
scale of operation, curtailed women’s participation in
the business of cheese production. Earlier, she
(15) maintained, women had concerned themselves with
feeding cows, rearing calves, and even selling the
cheese in local markets and fairs. Pinchbeck thought
that the advent of specialization meant that women’s
work in cheese dairying was reduced simply to
(20) processing the milk. “Dairymen” (a new social category)
raised and fed cows and sold the cheese through
factors, who were also men. With this narrowing of the
scope of work, Pinchbeck believed, women lost
business ability, independence, and initiative.
(25) Though Pinchbeck portrayed precapitalist,
preindustrial conditions as superior to what followed,
recent scholarship has seriously questioned the notion
of a golden age for women in precapitalist society. For
example, scholars note that women’s control seldom
(30) extended to the disposal of the proceeds of their
work. In the case of cheese, the rise of factors may
have compromised women’s ability to market cheese
at fairs. But merely selling the cheese did not
necessarily imply access to the money: Davidoff cites
(35) the case of an Essex man who appropriated all but a
fraction of the money from his wife’s cheese sales.
By focusing on somewhat peripheral operations,
moreover, Pinchbeck missed a substantial element
of continuity in women’s participation: throughout the
(40) period women did the central work of actually
making cheese. Their persistence in English cheese
dairying contrasts with women’s early disappearance
from arable agriculture in southeast England and
from American cheese dairying. Comparing these
(45) three divergent developments yields some reasons
for the differences among them. English cheese-
making women worked in a setting in which cultural
values, agricultural conditions, and the nature of
their work combined to support their continued
(50) participation. In the other cases, one or more of
these elements was lacking.

题目：

It can be inferred from the passage that women did work in

选项:

A、
American cheesemaking at some point prior to industrialization
B、
arable agriculture in northern England both before and after the agricultural revolution
C、
arable agriculture in southeast England after the agricultural revolution, in those locales in which cultural values supported their participation
D、
the sale of cheese at local markets in England even after the agricultural revolution

题目：

Until mow, only injectable vaccines against influenza have been available.  Parents are reluctant to subject children to the pain of injections, but adults, who are at risk of serious complications from influenza, are commonly vaccinated.  A new influenza vaccine, administered painlessly in a nasal spray, is effective for children.  However, since children seldom develop serious complications from influenza, no significant public health benefit would result from widespread vaccination of children using the nasal spray.
 
Which of the following is an assumption on which the argument depends?

选项:

A、Any person who has received the injectable vaccine can safely receive the nasal-spray vaccine as well.
B、The new vaccine uses the same mechanism to ward off influenza as jnjectable vaccines do.
C、The injectable vaccine is affordable for all adults.
D、Adults do not contract influenza primarily from children who have influenza.
E、The nasal spray vaccine is mot effective when administered to adults.

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.
