GMAT逻辑在文章内容的深入程度上虽然不如阅读,但其内部存在的各种逻辑关系却往往非常复杂。考生们想要提升GMAT逻辑CR得分,就需要在解题中注意整理归纳题目的逻辑关系链。下面小编会通过样题实例为大家做具体讲解分析。
GMAT逻辑题提分先学会整理逻辑链
众所周知,GMAT逻辑题考的是逻辑思维分析能力,而这种能力的体现在解答逻辑题的过程中就反映在大家的具体解题方法上。很多同学都是拿到题目之后看一遍文章大致理解意思就开始去和5个选项逐一对比,其实这样的做法还欠缺了一个环节。那就是考生主动去整理出这篇文章的逻辑关系。很多时候自己看过文章理解的意思往往是存在不少漏洞的,只有仔细写在草稿上才能看的比较清楚,这也是为什么很多人觉得自己明明看懂了文章但还是做错的原因之一。因此,在做GMAT逻辑题时学会先整理逻辑链再解题时很有必要的。
GMAT逻辑题逻辑链整理实例讲解
说了一些理论上的东西,有些同学可能还不太能理解。那么下面,我们就以一道样题为例看一下GMAT逻辑解题如何整理逻辑链。
逻辑样题实例:
Policymakers must confront the dilemma that fossil fuels continue to be an indispensable source of energy even though burning them produces atmospheric accumulations of carbon dioxide that increase the likelihood of potentially disastrous global climate change. Currently, technology that would capture carbon dioxide emitted by power plants and sequester it harmlessly underground or undersea instead of releasing it into the atmosphere might double the cost of generating electricity. But because sequestration does not affect the cost of electricity transmission and distribution, delivered prices will rise less, by no more than 50 percent. Research into better technologies for capturing carbon dioxide will undoubtedly lead to lowered costs.
1. The passage implies which of the following about the current cost of generating electricity?
A. It is higher than it would be if better technologies for capturing carbon dioxide were available.
B. It is somewhat less than the cost of electricity transmission and distribution.
C. It constitutes at most half of the delivered price of electricity.
D. It is dwelt on by policymakers to the exclusion of other costs associated with electricity delivery.
E. It is not fully recovered by the prices charged directly to electricity consumers.
具体分析:
对上文的逻辑进行提炼我们发现,得出这样一个逻辑推理链条:
环保技术(technology that would capture carbon dioxide emitted by power plants and sequester it harmlessly underground or undersea instead of releasing it into the atmosphere)增加一倍发电成本(double the cost of generating electricity)。环保技术不改变传输成本(the cost of electricity transmission and distribution)。最终价格(delivered prices)增加不超过50%。
最终价格=发电成本+传输成本。使用环保技术后,发电成本增加了原来的一倍,但是最终价格增长不超过50%,可以得出结论,发电成本,最多占最终价格的50%。也就是C选项。
通过对这道样题的分析,相信大家也能够看出整理好逻辑链对于解答GMAT逻辑题到底有多重要了,原本看似比较复杂的逻辑关系在理出逻辑链以后瞬间就变得十分清晰易懂。这也真是整理逻辑链对于解答逻辑题不可或缺的重要价值所在。
以上就是小编结合样题实例为大家讲解的GMAT逻辑提分技巧—逻辑链整理。希望上述方法能够帮助大家更快速有效地解答逻辑难题,在GMAT逻辑部分拿到更为理想的成绩。
