考生们复习GMAT考试逻辑的时候，要重点的关注一下GMAT逻辑中的经典题型。考生们平常复习逻辑的时候要大量的做模拟题，掌握经典题型的GMAT考试技巧。澳际小编下面给大家介绍几个经典题型：

　　①推论→事实型 (prep193)

　　Because it was long thought that few people would watch lengthy televised political messages, most televised political advertisements,like commercial advertisements,took the form of short messages.Last year,however,one candidate produced a half-hour-long advertisement.At the beginning of the half

　　hour slot a substantial portion of the viewing public had tuned in to that station.Clearly,then, many more people are interested in lengthy televised political messages than was previously thought. 削弱

　　逻辑链：更多的人对长广告感兴趣(推理)→有很大部分人将频道调回长广告(事实)

　　答案：这个广告在精彩的电视节目时段播出。

　　削弱：他因导致。即：并非人们对长广告感兴趣，而是因为精彩的电视节目才调回频道。(攻击推理)

　　②事实→推论型 (prep2-83)

　　Many people suffer an allergic reaction to sulfites,including those that are commonly added to wine as preservatives.However , since there are several winemakers producing wine to which no sulfites are added, those who would like to drink wine but are allergic to sulfites can drink these wines without risking an allergic reaction to sulfites. 削弱

　　逻辑链：一些酒没加硫磺(事实)→对硫磺过敏的人可以喝这种酒(推理)

　　答案：酒中自然产生硫磺

　　削弱：直接推翻结论。即：就算没有人为加硫磺，酒里也有可能有硫磺，所以喝这种酒还是有可能过敏，直接推翻结论。(攻击推理)

　　TIP：GMAT逻辑选项永远都不能质疑已定事实，只能在推理上做文章。

　　③措施→目的型 (prep2-92)

　　Editor: Articles in Gardening Magazine often spur sales of the plants they describe, particularly among people new to gardening. Accordingly, we will no longer publish articles or accept advertisements praising the beauty of rare wildflowers. Most such plants sold to gardeners have been difficult to propagate under cultivation, so plant sellers often collect them in the wild. Our new policy is part of our forts to halt this yearly plundering of our native plant populations. 削弱

　　逻辑链：不刊登稀有野花的文章(措施)→阻止野花的数量的减少(目的)

　　答案：卖植物的钱用来研究廉价的给野花授粉技术

　　削弱：GMAT考试其他因素阻碍目的达成。即：不刊登这类文章就没有卖植物的钱，也就失去授粉技术的资金，野花的数量还是会减少。

　　TIP：措施目的型的前提都是假设措施已实施!

　　④AB对比型 (prep2-103)

　　Electronic computer chips made of tiny silicon wafers now regularly contain millions of electronic switches. Unfortunately, electronic switches that are this small cannot withstand intense radiation. Micro-Mechanics plans to produce a chip that, because it uses only microscopic mechanical

　　switches, will be invulnerable to radiation damage. The switches will, however , be slower than electronic switches and the chip will contain only 12,000 switches. there to be a market for Micro-Mechanics&aposs chip as a result of the apparent advantage described above 削弱

　　逻辑链：M-M芯片比E芯片速度慢且转换器少，但抗辐射→M-M会有市场(M-M芯片比E芯片好)

　　答案：现在制造出的E芯片能抗辐射了

　　削弱：缩小比较对象AB的差距。即：A的优势没有那么明显

　　TIP：缩小AB之间的差距的概念是指，A的优势没有那么明显，并不是B一定得比A好

　　总结到最后会发现，GMAT考试技巧CR真的不难。不管题目怎么问都万变不离其宗，归根到底就在考逻辑链!

　　上述就是小编分享的GMAT考试逻辑的经典题型，我们解答GMAT逻辑题型的时候可以多参考一下上述的知识。感觉逻辑经典题型比较难的同学要多掌握一些GMAT考试技巧，最后祝同学们顺利考出好成绩。
