阅读理解 Women''s mind work differently from men''s at least, that is what most men are convinced of. Psychologists view the subject either as a matter of frustration or a joke. Now the biologists have moved into this minefield, and some of them have found that there are real social differences between the brains of men and women. But being different, they point out hurriedly, is not the same as being better or worse. There is, however, a definite structural variation between the male and female brain. The difference is in a part of the brain that is used in the most complex intellectual processes — the link between the two halves of the brain. The two halves are linked by a trunkline of between 200 and 300 million nerves, the corpus callosum(胼胝质). Scientists have found quite recently that the corpus callosum in women is always larger and probably richer in nerve fibres(纤维) than it in men. This is the first time that a structural difference has been found between the brains of women and men and it must have some significance. The question is "what?", and if this difference exists, are mere others? Research shows that present-day women think differently and behave differently from men. Are some of these differences biological and inborn, a result of evolution? We tend to think that is the influence of society that produces these differences. But could we be wrong? Research showed that these two halves of the brain had different functions, and that the corpus callosum enabled them to work together. For most people, the left half is used for word-handling, analytical and logical activities; the right half works on pictures, patterns and forms. We need both halves working together. And the better the connections, the more harmoniously the two halves work. And, according to research findings, women have the better connections. But it isn''t all that easy to explain the actual differences between skills of men and women on this basis. In schools throughout the world girls tend to be better than boys at "language subjects" and boys better at maths and physics. If these differences correspond with the differences in the hemispheric(半球的) trunkline, there is an unalterable distinction between the sexes. We shan''t know for a while, partly because we don''t know of any precise relationship between abilities in school subjects and the functioning of the two halves of the brain, and we cannot understand how the two halves interact via the corpus callosum. But this striking difference must have some effect and, because the difference is in the parts of the brain involved in intellect, we should be looking for differences in intellectual processing.
单选题 Which of the following statements is CORRECT?
【正确答案】 C
【答案解析】判断题。可以通过逐一分析解题。A中的“心理学家已经放弃”文中未曾出现,所以是错的。B与第一段的But being different,they point out hurriedly,is not the same as being better or worse(存在不同并不说明两种人脑有优劣之分)意思完全相反,所以是错的。D与第三段的This is the first time that a structural difference has been found between the brains of women and men(这是人们首次发现男女大脑在结构上的不同)意思相反,所以也是错的。第三段还提到:We tend to think that is the influence of society that produces these differences(过去我们认为是社会的影响造成了男女思维和行为的不同),意思就是过去我们的看法和现在的科学研究的结论不同,因此正确的答案是C。
单选题 According to the passage it is commonly believed that brain differences are caused by ________factors.
【正确答案】 D
【答案解析】细节题。定位的内容出现在第三段:We tend to think that is the influence of society that produces these differences.(过去我们认为是社会的影响造成了男女思维和行为的不同),答案是D。
单选题 these differences in paragraph 5 refers to those in________.
【正确答案】 A
【答案解析】指代题。指示代词these一般指代前文出现的同类内容,在第五段,作者主要举例说明男女在能力方面有性别不同,例子是学校课程中男生以理科取胜,女生在语言方面学得更好,接下来出现these differences,一定指的是能力的不同。答案是A。
单选题 At the end of the passage the author proposes more work on________.
【正确答案】 B
【答案解析】分析推理题。文章的最后一段提出了几个悬而未决的问题,例如precise relationship between abilities in school subjects and the functioning of the two halves of the brain(学校的学习能力和人脑两半球功能之间存在什么具体的关系)和how the two halves interact via the corpus callosum(两半球如何通过胼胝质体互动),所有这些问题都要求研究人脑的各部分——左脑、右脑和胼胝质体。因此答案是B。
单选题 What is the main purpose of the passage?
【正确答案】 B
【答案解析】主旨题。本文主要介绍了人脑结构不同与两性行为、思维、能力的关联。未曾涉及人脑研究的其他领域,所以A是错误的。关于人脑不同的发现,文章也只提到男女胼胝质体的不同,因此C是错误的,文章的最后一段建议对于人脑结构进行更深入细致的研究,但没有提到新的领域,所以D是错误的。正确的答案是B。
