By 1950, the results of attempts to relate brain processes to mental experience appeared rather discouraging. Herring suggested that different modes of
Line sensation, such as pain, taste, and color, might be
5 correlated with the discharge of specific kinds of nervous energy. However, subsequently developed methods of recording and analyzing nerve potentials failed to reveal any such qualitative diversity. Although qualitative variance among nerve energies was never rigidly
10 disproved, the doctrine was generally abandoned in favor of the opposing view, namely, that nerve impulses are essentially homogeneous in quality and are transmitted as ―common currency‖ throughout the nervous system. According to this theory, it is not the quality of the
15 sensory nerve impulses that determines the diverse conscious sensations they produce, but rather the different areas of the brain into which they discharge, and there is some evidence for this view. In one experiment, when an electric stimulus was applied to a given sensory field of
20 the cerebral cortex of a conscious human subject, it produced a sensation of the appropriate modality for that particular locus, that is, a visual sensation from the visual cortex, an auditory sensation from the auditory cortex, and so on. However, cortical locus, in itself, turned out to
25 have little explanatory value.
3. Which of the following best summarizes the
author‘s opinion of the suggestion that different
areas of the brain determine perceptions produced
by sensory nerve impulses?
(A) It is a plausible explanation, but it has not been
completely proved.
(B) It is the best explanation of brain processes
currently available.
(C) It is disproved by the fact that the various areas
of the brain are physiologically very similar.
(D) There is some evidence to support it, but it fails
to explain the diversity of mental experience.
(E) There is experimental evidence that confirms its
correctness.
答案D,文中在哪里提到了这种假说不能解释diversity of mental experience了啊?
A Marxist sociologist has argued that racism stems
from the class struggle that is unique to the capitalist
system—that racial prejudice is generated by capitalists
Line as a means of controlling workers. His thesis works
5 relatively well when applied to discrimination against
Blacks in the United States, but his definition of racial
prejudice as ―racially-based negative prejudgments
against a group generally accepted as a race in any
given region of ethnic competition,‖ can be interpreted
10 as also including hostility toward such ethnic groups as
the Chinese in California and the Jews in medieval
Europe. However, since prejudice against these latter
peoples was not inspired by capitalists, he has to reason
that such antagonisms were not really based on race.
15 He disposes thusly (albeit unconvincingly) of both the
intolerance faced by Jews before the rise of capitalism
and the early twentieth-century discrimination against
Oriental people in California, which, inconveniently,
was instigated by workers.
4. The passage supplies information that would
answer which of the following questions EXCEPT?
□A What conditions caused the discrimination
against Oriental people in California in the
early twentieth century?
□B What evidence did the Marxist sociologist
provide to support his thesis?
□C What explanation did the Marxist sociologist
give for the existence of racial prejudice?
答案AB,原文中最后一句话说He disposes thusly (albeit unconvincingly) of both the
intolerance faced by Jews before the rise of capitalism
and the early twentieth-century discrimination against
Oriental people in California, which, inconveniently,
was instigated by workers.
是不是instigate by worker只能算原因而不是一种condition啊?
A mysterious phenomenon is the ability of over-water migrants to travel on course. Birds, bees, and other species can keep track of time without any sensory cues
Line from the outside world, and such ―biological clocks‖
5 clearly contribute to their ―compass sense.‖ For example, they can use the position of the Sun or stars, along with the time of day, to find north. But compass sense alone cannot explain how birds navigate the ocean: after a flock traveling east is blown far south by a storm, it will
10 assume the proper northeasterly course to compensate. Perhaps, some scientists thought, migrants determine their geographic position on Earth by celestial navigation, almost as human navigators use stars and planets, but this would demand of the animals a fantastic map sense.
15 Researchers now know that some species have a magnetic sense, which might allow migrants to determine their geographic location by detecting variations in the strength of the Earth‘s magnetic field.
The main idea of the passage is that
(A) migration over land requires a simpler
explanation than migration over water
does
(B) the means by which animals migrate over
water are complex and only partly
understood
(C) the ability of migrant animals to keep track
of time is related to their magnetic sense
(D) knowledge of geographic location is
essential to migrants with little or no
compass sense
(E) explanations of how animals migrate tend to
replace, rather than build on, one
another
答案选B,partially understood是怎么体现出来的?后面不是给出明确的解释了吗?而且E选项为何不可?
Tillie Olsen‘s fiction and essays have been widely and rightly acknowledged, particularly by contemporary feminists, as major contributions to American
Line literature. Yet few of Olsen‘s readers realize the extent
5 to which her vision and choice of subject are rooted in an earlier literary heritage—the tradition of radical political thought, mostly socialist and anarchist, of the 1910‘s and 1920‘s, and the Old Left tradition of the 1930‘s. I do not mean that one can adequately explain
10 the eloquence of her work in terms of its political origins, or that left-wing politics were the single most important influence on it. My point is that its central consciousness—its profound understanding of class and gender as shaping influences on people‘s lives—owes
15 much to that earlier literary heritage.
7. According to the author, which of the following
is NOT true of the heritage mentioned in the passage?
□A It emphasizes gender as the determinate
influence on people‘s lives.
□B It includes political traditions that span three
decades of the twentieth century.
□C It has been the most important influence on
Olsen‘s work.
答案:AC,文章最后一句话不是说gender as the determinate
influence on people‘s lives. owe much to that earlier literary heritage吗? 这个说的不是A吗?
Jean Wagner‘s most enduring contribution to the study of Afro-American poetry is his insistence that it be analyzed in a religious, as well as secular, frame of
Line reference. The appropriateness of such an approach may
5 seem self-evident for a tradition commencing with spirituals and owing its early forms, rhythms, vocabulary, and evangelical fervor to Wesleyan hymnals. But before Wagner a secular outlook that analyzed Black poetry solely within the context of political and social protest
10 was dominant in the field.
It is Wagner who first demonstrated the essential fusion of racial and religious feeling in Afro-American poetry. The two, he argued, form a symbiotic union in which religious feelings are often applied to racial issues
15 and racial problems are often projected onto a metaphysical plane. Wagner found this most eloquently illustrated in the Black spiritual, where the desire for freedom in this world and the hope for salvation in the next are inextricably intertwined.
3. It can be inferred from the passage that, before
Wagner, most students of Afro-American poetry did
which of the following?
(A) Contributed appreciably to the transfer of
political protest from Afro-American poetry to
direct political action.
(B) Ignored at least some of the historical roots of
Afro-American poetry.
(C) Analyzed fully the aspects of social protest
to be found in such traditional forms of Afro-
American poetry as the Black spiritual.
(D) Regarded as unimportant the development
of fervent emotionalism in a portion of Afro-
American poetry.
(E) Concentrated on the complex relations
between the technical elements in Afro-
American poetry and its political content.
答案:b, 我也选对了,但是我感觉那个“some of the historical roots of
Afro-American poetry”和原文的从宗教角度来进行分析不是很对应啊。 |
