GRE阅读题目解析:脑左顶叶损伤症状

2017-12-04 11:48:00来源：网络

　　P37

　　1

　　In the 1920s, Gerstmann described a set of problems found in people who have suffered damage to the brain’s left parietal lobe, problems that include being unable to understand arithmetic and having difficulty identifying one’s fingers.

　　1920 年代，G 描述了一系列脑左顶叶损伤的病人的症状，包括无法算术以及难以辨识手指。

　　(parietal 颅腔壁的，顶骨的

　　arithmetic 算术的)

　　2

　　There is still no agreement on whether the symptoms Gerstmann noticed constitute a syndrome, but the parts of the brain used for storing facts about numbers and for representing the fingers are close to each other.

　　G 提及的这些症状是否可以归为一个症候群，尚有争议，但大脑用来存储数字信息的部分，和描述手指的部分的确离得很近。

　　3

　　Mental representations of numbers and of fingers may therefore be functionally connected.

　　因此，数字和手指在脑海中的呈现也许有功能上的联系。

　　4

　　A 2005 experiment had people perform some tasks requiring dexterity and others involving matching pairs of numbers, while an area of their parietal lobes — the left angular gyrus — was stimulated by a magnetic field.

　　一项 2005 年的实验，让参与者执行一些需要技巧及涉及数字配对的任务，同时他们顶叶的一个区域 —— 左角回 —— 被磁场干扰。

　　(angular 有角的，骨瘦嶙峋的，生硬笨拙的，固执的

　　gyrus 脑回(大脑表面凸起被称为脑回，凹进称为脑沟，合称沟回))

　　5

　　Facility at both sets of tasks was impaired.

　　结果两组都不能很好地完成任务。

　　(facility 容易学好或做好的能力，(做某事的)辅助条件、有利条件)

　　1. The author of the passage would most likely agree that the highlighted statement suggests

　　A. a flaw in the experiment conducted in 2005

　　B. a means by which dexterity might compensate for a loss of arithmetic ability

　　C. an explanation for some of Gerstmann’s observations

　　D. an anomaly in some of Gerstmann’s results

　　E. a reason to doubt damage to the left parietal lobe as a causal factor in certain symptoms

　　选 C

　　没啥讲的。

　　2. The author of the passage describes the “2005 experiment” and its results primarily in order to

　　A. establish the proximity between the part of the brain used for storing numerical information and the part used for representing the fingers

　　B. illustrate the implications that Gerstmann’s work may have for experimental research

　　C. cast doubt on the idea that damage to the left parietal lobe causes the set of problems that Gerstmann described

　　D. support a hypothesis about a significant association between parts of the brain related to fingers and to numbers

　　E. suggest that the problems Gerstmann noted in relation to numbers and fingers have a different cause than the other problems associated with parietal lobe damage

　　选 D

　　hypothesis 指的是句 3： Mental representations of numbers and of fingers may therefore be functionally connected.

　　句 3 说可能有联系，2005 年的实验证明了的确有联系。
