2018官方GRE真题解析_GRE阅读真题解析二_雷哥GRE
GRE阅读，尤其是长阅读对于GRE考生来说可谓是最头疼的项目。头疼的点不仅在于阅读量大，同学们往往无法读完文章，还在于做完题后，无法获得精准的真题解析。意思就是：我做了，错了，不知道错在哪里。
网上有很大一部分人鼓吹：GRE不就是一个背单词吗，单词背好了，就能解决GRE。雷哥GRE以专业身份告诉你，这个说法大错特错。GRE词汇量的高要求仅相当于一个备考基础，打好了这个根基，我们才能在上面建起大厦。
从GRE阅读我们就不难看出，单词量积累了能读完文章，是不是又发现自己依旧搞不定长阅读？等到好不容易能读完文章了，是不是又发现自己不会做题！在雷哥GRE杀G备考群里，“想请教大家一下长阅读怎么办”这个问题也是隔一段时间就要被提起一次。
R妹就想告诉大家，GRE长阅读更注重考察的是对文章逻辑结构的把握，就好比做完阅读题后，我们对着光秃秃的ABCD选项改错有用吗？知其然知其所以然，GRE真题的最好利用方式是——解读GRE真题，弄清GRE真题解析思路，获取老师的正确GRE思维，学会回文定位。
所以GRE阅读做起来感觉困难，绝大多数同学都是方法不对，一字一句全部翻译肯定不是学习GRE阅读的正确方法。R妹会持续分享给大家阅读的GRE真题，做完后请大家对照真题解析，发掘自己的思维漏洞，早日攻克GRE阅读难关！
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.
1. The author mentions ―common currency‖ in line 13
primarily in order to emphasize the
(A) lack of differentiation among nerve impulses in
human beings
(B) similarity of the sensations that all human
beings experience
(C) similarities in the views of scientists who have
studied the human nervous system
(D) continuous passage of nerve impulses through
the nervous system
(E) recurrent questioning by scientists of an
accepted explanation about the nervous
system
2. The description of an experiment in which electric
stimuli were applied to different sensory fields of the
cerebral cortex tends to support the theory that
(A) the simple presence of different cortical areas
cannot account for the diversity of mental
experience
(B) variation in spatiotemporal patterning of nerve
impulses correlates with variation in
subjective experience
(C) nerve impulses are essentially homogeneous
and are relatively unaffected as they travel
through the nervous system
(D) the mental experiences produced by sensory
nerve impulses are determined by the
cortical area activated
(E) variation in neuron types affects the quality of
nerve impulses
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.
解析：
1. 定位到第 11 行：
―that nerve impulses are essentially
homogeneous in quality and are transmitted
as ―common currency throughout the nervous
system.‖ 每一句话都透露着一种
关于 nerve impulse 的一致、同一的感觉。
2. 定位到文章第二十行：可以直接得出答案
“it produced a sensation of the appropriate
modality for that particular locus,
that is, a visual sensation from the visual
cortex‖
3. 结合上一句的每种 locus 对应不同的 sensation；
每个之间不具备分析的价值。
“However, cortical locus, in itself, turned out
to have little explanatory value.”
