GMAT逻辑的题型比较多,针对GMAT逻辑题目也就有多种相应的解决方法,今天为大家特意分享的是GMAT逻辑假设题的解决方法,供大家备考学习,希望对正在备考GMAT逻辑的朋友们有帮助。下面就和小编一起看一下GMAT逻辑假设题的解决方法吧。
ASSUMPTION题,作为GMAT逻辑题型的一种,也就是我们俗称的假设题,需要同学们选出选项作为原文结论成立的必要条件,使得文章结论成立的可能性提高。标志性词语:assumption、an addition premise、depend on,假设题是逻辑题考察的重点,与削弱题密切相关。本文就把GMAT逻辑假设题解题思路给大家介绍下。 一、GMAT逻辑假设题正确答案特点 1.含有”at least one” 或”at least some”是正确的可能性很高用取非”none”检验。 2.避免选择带有”the primary purpose”, “the top priority”或”the main factor”等宣称是作者 重要观点的词的选项。 3.注意选项中出现”not”不一定是错误答案,反而defender中经常用到not, no, never等否定词。 注:因果类假设与加强做法类似,即: 1)排除他因 2)有因必有果 3)无因必无果 4)因果不颠倒 5)使用的证据或数据真实有效或排除其无效的可能性 二、GMAT逻辑假设题错误答案特点 1)相反答案(即削弱) 2)伪装答案——答案加强了一个与原文结论相似的结论 3)无关答案 三、GMAT逻辑解题技巧 1、找出原文中的结论 2、锁定结论,几乎所有正确答案都对结论有影响 3、原文中有推理漏洞,需要仔细寻找加以支持 4、预先判断正确选项特征范围 四、GMAT逻辑假设题真题解析 OG13-P512-41 Installing scrubbers in smokestacks and switching to cleaner-burning fuel are the two methods available to Northern Power for reducing harmful emissions from its plants. Scrubbers will reduce harmful emissions more than cleaner-burning fuels will. Therefore, by installing scrubbers, Northern Power will be doing the most that can be done to reduce harmful emissions from its plants. Which of the following is an assumption on. which the argument depends? (A) Switching to cleaner-burning fuel will not be more expensive than installing scrubbers. (B) Northern Power can choose from among various kinds of scrubbers, some of which are more effective than others. (C) Northern Power is not necessarily committed to reducing harmful emissions from its plants. (D) Harmful emissions from Northern Power's plants cannot be reduced more by using both methods together than by the installation of scrubbers alone. (E) Aside from harmful emissions from the smokestacks of its plants, the activities of Northern Power do not cause significant air pollution. 解析:在烟囱上安装清洁器和转向使用清洁能源是NP公司减排的两种方案,清洁器比清洁能源效果好,所以只要安装了清洁器,NP就在 大程度上实现了减排。 下面哪一个选项是题目结论所依赖的假设条件。 选项A, 谈成本,无关属性,排除! 选项C,谈减排的必要性,无关属性,排除! 选项D,两种方式同时使用不会在大程度上实现减排。取反验证,假设两种方式同时使用可以在大程度上减排那么题干结论被推翻,正确! 选项E,ASIDE FROM HARMFUL EMISSION直接排除!
