文章:

Line Behind every book review there are two key figures:
a book review editor and a reviewer. Editors decide
whether a book is reviewed in their publication, when
the review appears, how long it is, and who writes the
(5) review.
When many periodicals feature the same books,
this does not prove that the editors of different
periodicals have not made individual decisions.
Before publication, editors receive news releases and
(10) printer’s proofs of certain books, signifying that the
publishers will make special efforts to promote these
books. They will be heavily advertised and probably
be among the books that most bookstores order in
quantity. Not having such books reviewed might give
(15) the impression that the editor was caught napping,
whereas too many reviews of books that readers will
have trouble finding in stores would be inappropriate.
Editors can risk having a few of the less popular
titles reviewed, but they must consider what will be
(20) newsworthy, advertised, and written about elsewhere.
If these were the only factors influencing editors,
few books that stand little chance of selling well would
ever be reviewed. But editors feel some concern
about what might endure, and therefore listen to
(25) literary experts. A generation ago, a newspaper used
a brilliant system of choosing which books to feature.
The book review editor sent out a greater number of
books than reviews he actually intended to publish.
If a review was unenthusiastic, he reasoned that the
(30) book was not important enough to be discussed
immediately, and if good reviews of enough other
books came in, the unenthusiastic review might never
be printed. The unenthusiastic reviewers were paid
promptly anyway, but they learned that if they wanted
(35) their material to be printed, it was advisable to be
kind.
Most editors print favorable and unfavorable
reviews; however, the content of the review may be
influenced by the editor. Some editors would actually
(40) feel that they had failed in their responsibility if they
gave books by authors they admired to hostile critics
or books by authors they disapproved of to critics
who might favor them. Editors usually can predict who
would review a book enthusiastically and who would
(45) tear it to shreds.

文章:

In a new book about the antiparty feeling of the early political leaders of the United States, Ralph Ketch am argues that the first six Presidents differed decisively from later Presidents because the first six held values inherited from the classical humanist tradition of eighteenth-century England. In this view, government was designed not to satisfy the private desires of the people but to make them better citizens; this tradition stressed the disinterested devotion of political leaders to the public good. Justice, wisdom, and courage were more important qualities in a leader than the ability to organize voters and win elections. Indeed, leaders were supposed to be called to office rather than to run for office. And if they took up the burdens of public office with a sense of duty, leaders also believed that such offices were naturally their due because of their social preeminence or their contributions to the country. Given this classical conception of leadership, it is not surprising that the first six Presidents condemned political parties. Parties were partial by definition, self-interested, and therefore serving something other than the transcendent public good.


Even during the first presidency (Washington's), however, the classical conception of virtuous leadership was being undermined by commercial forces that had been gathering since at least the beginning of the eighteenth century. Commerce—its profit-making, its self-interestedness, its individualism—became the enemy of these classical ideals. Although Ketch am does not picture the struggle in quite this way, he does rightly see Jackson's tenure (the seventh presidency) as the culmination of the acceptance of party, commerce, and individualism. For the Jacksonians, nonpartisanship lost its relevance, and under the direction of Van Buren, party gained a new legitimacy. The classical ideals of the first six Presidents became identified with a privileged aristocracy, an aristocrat that had to be overcome in order to allow competition between opposing political interests. Ketcham is so strongly committed to justifying the classical ideals, however, that he underestimates the advantages of their decline. For example, the classical conception of leadership was incompatible with our modem notion of the freedoms of speech and press, freedoms intimately associated with the legitimacy of opposing political patties.

题目:

The author of the passage would be most likely to agree with which of the following statements about Ketch am?

选项:

A、He overemphasizes the influence of classical ideals on the first six Presidents of the United States.
B、He fails to recognize that classical ideals had little influence on politics in the United States. 
C、He does not pay adequate attention to the negative aspects of the first six Presidents' commitment to classical ideals. 
D、He inaccurately suggests that classical ideals gave r ise to our modem notion of democracy. 
E、He underestimates the effect of ideologies other than the humanist tradition on the first six Presidents.

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.
