GMAT逻辑，本质是搞清楚原文讨论的是逻辑对象间的何种逻辑关系，正确选项一定是对其逻辑关系的描述或者能够影响其逻辑关系。以下是两种比较常见的的逻辑题目类型，请看下面例题：1.Some anthropologists study modern-day societies of foragers in an effort to learn about our ancient ancestors who were also foragers. A ?aw in this strategy is that forager societies are extremely varied. Indeed, any forager society with which anthropologists are familiar has had considerable contact with modern, non-forager societies. Which of the following, if true, would most weaken the criticism made above of the anthropologists’ strategy? (A) All forager societies throughout history have had a number of important features in common that are absent from other types of societies.(B) Most ancient forager societies either dissolved or made a transition to another way of life.(C) All anthropologists study one kind or another of modern-day society.(D) Many anthropologists who study modern-day forager societies do not draw inferences about ancient societies on the basis of their studies.(E) Even those modern-day forager societies that have not had significant contact with modern societies are importantly different from ancient forager societies.分析：原文：以对现代原始人社会的研究来学习原始祖先，反对者：现代原始人与非原始人有接触问题：对批判的削弱。本题属于类比论证，比较对象为现代原始社会与古老原始社会；问题转化为类比成立，答案为二者有相同。A， 所有原始社会有区别于其他社会的重要的共同特征；B， 大部分原始社会或者消失或者转向其他生活方式；C，所有的人类学家都学习一种现代社会；D， 研究现代原始社会的人类学家并不依据其研究来得出关于原始社会的推论；E， 甚至是那些与现代社会有重要联系的原始社会与古老原始社会是显著不同的。答案：选 A。2.Most employees in the computer industry move from company to company, changing jobs several times in their careers. However, Summit Computers is known throughout the industry for retaining its employees. Summit credits its success in retaining employees to its informal, nonhierarchical work environment. Which of the following, if true, most strongly supports Summit’s explanation of its success in retaining employees? (A) Some people employed in the computer industry change jobs if they become bored with their current projects.(B) A hierarchical work environment hinders the cooperative exchange of ideas that computer industry employees consider necessary for their work.(C) Many of Summit’s senior employees had previously worked at only one other computer company.(D) In a nonhierarchical work environment, people avoid behavior that might threaten group harmony and thus avoid discussing with their colleagues any dissatisfaction they might have with their jobs.(E) The cost of living near Summit is relatively low compared to areas in which some other computer companies are located. 原文：informal, nonhierarchical work environment----success in retaining employees问题：支持关键：逻辑重心把握，有关无关判断。选项：A， 如果员工对当前项目没兴趣就会换工作；条件性定义，无关；B， 层级工作环境阻碍了思想交流；有关；C， 很多高级员工只换过一次工作；无关；D， 在非层级工作环境，人们可以避免影响集体的行为，避免探讨对工作的任何不满；绝对化表达，错误的有关；E， 生活成本低； 无关比较。答案：B。 |
