做ＯＧ的时候分类去做，（分类是指Assumption, weaken, strengthen等等），这样可以 加强对每一个题型的概念。对於ＣＲ正确率不高的同学，建议每次检讨的时候做一个小总 结。ＣＲ的总结不向ＳＣ一样很明显，需要思考一下，找到题目背後的观念，并且自己写 成像是公式般的总结。举例来说： In the United States, of the people who moved from one state to another when they retired, the percentage who retired to Florida has decreased by three percentage points over the past ten years. Since many local businesses in Florida cater to retirees, these declines are likely to have a noticeably negative economic effect on these businesses and therefore on the economy of Florida. Which of the following, if true, most seriously weakens the argument given? (A) People who moved from one state to another when they retired moved a greater distance, on average, last year than such people did ten years ago. (B) People were more likely to retire to North Carolina from another state last year than people were ten years ago. (C) The number of people who moved from one state to another when they retired has increased significantly over the past ten years. (D) The number of people who left Florida when they retired to live in another state was greater last year than it was ten years ago. (E) Florida attracts more people who move from one state to another when they retire than does any other state. 解题思路：我习惯把题目读进脑里，对我来说比较像是看一篇小短文，而不是急着看过题 目然後找论点架构。而ＣＲ的每一篇都会想要说服大家一件事（这应该就是所谓的论点） ，有时候我读完文章之後会觉得我没找到那个＂点＂，这时候我宁愿花时间在读一次文章 ，而不是抱着＂也许我看了题目和选项就会知道答案＂的心态。所以看完题目之後我对题 目的理解是：退休之後都会搬到Florida的百分比变低了，因为在Florida的店家都是靠退 休的人做生意，所以他们生意变差，Florida的经济也变差。答案：Ｃ：退休後搬家的总 人数变多。退休後总人数变多，所以即使搬去Florida的百分比变少，但搬去Florida的总 人数不一定变少。 这题的总结我会写：(Weaken)真正的数目＝百分比ｘ总人数，所以如果总人数有变动，百 分比的变动不可以断定真正的数目是增加还是减少。 其实这个总结在ＣＲ很常出现，可以应用在其他题型。做总结的目的，除了一方面熟悉 GMAT喜欢用什麽样的盲点／逻辑来考我们。还有有时候看完题目後再选项找不到答案的时 候，可以回想一下这个类型的题型我曾经做过什麽总结，在选项里找看看有没有这样的答 案。 另外有一个我以前很常犯的错误：利用关键字找答案／删答案。因为CR题型很常会有正确 答案是借由排除其他可能，去加强论点。所以可能整个选项没有题目的关键字。 ----------------- Vic (770 V42 Q51) Facebook GMAT交流板 https://www.facebook.com/groups/VicGMAT/ 4周速成实力班 http://ndxica.pixnet.net/blog/post/40937209 --
