23. On a certain day, nine scheduled flights on Swift Airlines were
canceled. Ordinarily, a cancellation is due to mechanical problems with
the airplane scheduled for a certain flight. However, since it is
unlikely that Swift would have the mechanical problems with more than
one or two scheduled flights on a single day, some of the nine
cancellations were probably due to something else.

  (A) More than one or two airplanes were scheduled for the nine canceled flights.

  (B) Swift Airlines has fewer mechanical problems than do other airlines of the same size.

  (C) Each of the canceled flights would have been longer than the average flight on Swift Airlines.

  (D) Swift Airlines had never before canceled more than one or two scheduled flights on a single day.

  (E) All of the airplanes scheduled for the canceled flights are based at the same airport.


答案A说取非削弱,B~D无关 我就是怎么也看不出来怎么削弱,诚信向各位请教!

还有咨询一下,我虽然刚开始复习逻辑不就,不记时间慢慢看,正确率一半以下。。。。说的很好的LAWYER感觉有点太抽象了条条框框的我和题目根本很难对应起来,我还是在努力看,但是心态很不好,越来越慌~~

恳请大家贡献下自己的经验,刚起步是这样吗,做逻辑的正确方法大概是什么呢,一道的时间应该是多少呢~~~


感谢赐教,快考试了~~ 各位复习、学习一切顺利!!!!!

原文的论据是:
1. Ordinarily, a cancellation is due to mechanical problems with the airplane scheduled for a certain flight. 
2. since it is unlikely that Swift would have the mechanical problems with more than
one or two scheduled flights on a single day

lz看到了没有,两个论据的出现跳跃了(也就是大家常说的推理上的GAP),第一个在讲airplane(飞机),而第二个已经到了flights(航班)。所以assumption一定要把这两个元素进行一个链接,那只有A在链接。考试的时候思路是这样的。

那在仔细分析一下,如果把A取非,那么就是说着九个flight(航班)都由一个飞机来执飞,那这样的话,第二个论据就站不住脚了(这个唯一的飞机坏了,那么九个航班当然要取消了,这就不是什么unlikely的事情,而是likely了)。

lawyer的总结是高度概括的,刚开始的话当然很难对应上啦,不要着急。我当时把og做完一边以后,把每道题的逻辑基本弄懂了,然后就开始参考lawyer的总结进行第二遍的og,这个时候就会很有感觉啦。至于做题时间么,我个人觉得平均下来verbal每题是1分40秒,但lz要平衡自己做rc,rc,sc的具体情况,来决定每个类型的题目应该是多少为好。

二楼好强大
果然有问题了就来CD看看牛人的解释然后就豁然开朗啊
比自己蒙头想好久有用多了
thanks
