　　每道题剔除各种背景信息，提炼出简化的逻辑链，然后依次纵向罗列出来逻辑链的种类可分为四种类型：推理→事实型(文章给出已有的事实，推断导致该事实的原因);事实→推理型(文章给出已有的事实，推断事实导致的结果);措施→目的型(为了达到一目的，建议采用某个措施)，AB对比型(Eg: A比B好，A比B经济，etc.)将每题正确答案分别写在逻辑链下，看它是从逻辑链哪个环节切入达到削弱/加强/评价/假设的目的。最后归纳总结不同类型逻辑链所对应的解题方式。

　　GMAT逻辑分类总结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)

　　GMAT逻辑分类总结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：选项永远都不能质疑已定事实，只能在推理上做文章。

通过上面的GMAT逻辑分类总结，可以发现CR真的不是十分困难。不管题目怎么问都是万变不离其宗的，归根到底都是在考察逻辑链，最后祝大家都能考出好成绩。
