础应该打牢了.
最后， 将错误选项分类中的无关选项/弱相关/相反等选项，分别单独筛选出来过一遍。
这些过后，对于基础差的童靴，对CR的领悟应该很强大了

举例分步详解：
OG12-30.
Robot satellites relay important communications and identify weather patterns. Because the satellites can be repaired only in orbit, astronauts are needed to repair them. Without repairs, the satellites would eventually malfunction. Therefore, space flights carrying astronauts must continue. Which of the following, if true, would most seriously weaken the argument above?
第一遍，只读题干，写逻辑链条（记录所用时间）。
Conclusion: the aircraft with astonuauts must continue;
Premsie: because the satellites could be repaired only in the orbit, and if not to be repaired, the satellites will be malfunction.
就这样，将OG12的124道CR题逻辑链条书写一遍。只写逻辑链条，不phrase，忍住啊。
第二遍，再来一遍，只读题干，写逻辑链条（记录所用时间）。
Conclusion: the aircraft with the astronauts should be continued.
Premise: the satellites need to be repaired and if the satellites is not repaired, the satellites will be malfunction
就这样，将OG12的124道CR题逻辑链条书再写一遍。同样，只写逻辑链条，不phrase，继续忍住啊。
第三遍，读自己第二遍整理出来的逻辑链条，只去phrase正确答案，千万不要去读选项。（phrase时候尽量与原文答案中的内容不同，如果10S过去还未phrase出来，那phrase的选项可以采用原题中的选项）
首先，练习weaken phrase.
自己Phrase 一个会Weak逻辑链条的答案：The new aircraft with the robot engineers who could repair the satellites in the orbit is more effective at repairing satellites error
就这样，将OG12中的WEAKEN, STRGTHEN,ASSUMPTION,和EVALUATION所有题从EXCEL表中filter出来。读自己第二遍整理出来的这些题的逻辑链条后，只去phrase 如何weak这个逻辑链条。
然后，练习strengthen phrase
自己Phrase 一个会strengthen逻辑链条的答案：The astronauts work more effectively than the robots to repair the malfunction of satellites.
就这样，将OG12中的WEAKEN, STRGTHEN,ASSUMPTION,和EVALUATION所有题从EXCEL表中filter出来。读自己第二遍整理出来的这些题的逻辑链条后，只去phrase 如何strengthen这个逻辑链条。
其次，练习assumption phrase---只去做相应的assumption题就够了。
OG12-50. Although computers can enhance people's ability to communicate, computer games are a cause of
underdeveloped communication skills in children. After-school hours spent playing computer games are
hours not spent talking with people. Therefore, children who spend all their spare time playing these games have less experience in interpersonal communication than other children have.
自己Phrase 一个assumption题型的答案: Except the after-school hours, the children who spend more time on the computer will not be more likely to communicate with others
就这样，将OG12中的ASSUMPTION题从EXCEL表中filter出来。读自己第二遍整理出来的这些题的逻辑链条后，只去phrase 如何assumption。
第四遍，将那些在第二遍时候，读题干书写逻辑链条时，超过30s的题目统统的拿出来，再重复几次，直到可以达到书写逻辑链条的时间小于30s。
OG12-120. The earliest Mayan pottery found at Colha, in Belize, is about 3,000 years old. Recently, however, 4,500-year-old stone agricultural implements were unearthed at Colha. These implements resemble Mayan stone implements of a much later period, also found at Colha. Moreover, the implements' designs are strikingly different from the designs of stone implements produced by other cultures known to have inhabited the area in prehistoric times. Therefore, there were surely Mayan settlements in Colha 4,500 years ago.
仅仅书写逻辑链条（记录所用时间）：
Conclusion: The M lived there 4500 years ago.
Premise: because the stone implement dated to be 4500 years ago is likely to be M. Furthermore, the stone implement is not likely to be other civilizations.
就这样，将不停重复直到所有124道OG12题的书写逻辑链条的时间小于30s。
最后， 将错误选项分类中的无关选项/弱相关/相反等选项，分别单独筛选出来过一遍。这些过后，对于基础差的童靴，对CR的领悟应该很强大了。
错误选项分类五花八门，无论大家曾经用过哪些方法，都可以的（个人认为，BIBLE CR会清晰些）。重要的是通过专项训练形成对某一类选项的强烈反射。
框架：练习了第一遍，和第二遍之后，会对CR题干形成一个框架，再怎么变CR就是这么个框架，而且实战中，我一直在找可以囊括这四句话的题，记得只有一道题，其他题俩三句话就是个题干了（这4句话可能顺序会打乱）：
First sentence: Context(lots of professional words,Names or Places,出题人用来吓唬人的，下面有写具体解决方法。);
Second sentence: Some.. /Phenomenon / Problem;
Third sentence : However;moreover;other… /Phenomenon / Plan to solve the problem/;
Forth sentence: Thus/therefore,…
TIPS:练习时候的可能用到的：
context中的那些吓人单词： 简单化--长的公司名字，组织名字或则生物名词，简单化后，就是公司，机构，器官或细胞；
第二句到第四句中绕来绕去的逻辑关系： 形象化-- 尽量想象成自己熟悉的流程或则对象,比如OG12-34，feed cattles and chickens题，就想象自己在农场里喂这些动物; OG12-112,俩个国家的电视进出口比较, 就想象american and china;
Kingarthur方法总结：
Nature：读懂题
Trick：CR解题步骤分解+专注训练
整理了下OG12-124道CR题，当时按照这个流程做的EXCEL表，请见附件。因为所有流程我都是卡时间做的，可能有些英文表达不是很到位，或则漏了个别题。
