个人觉得逻辑考的就是阅读能力， 开始我将og反反复看了3遍，对每一个题都做了总结，发先了很多的套路，比如说，由a到b . 如果要weaken的话， 可以直接攻击a 的立足点，获得寻找另一个原因。同样的 ，如果要支持就rule out 其他原因。 这些东西都是直接总结的， 个人认为只有这样才能训练出感觉。后来开始gwd ， 发现gwd 的逻辑题信息量很大。 对阅读能力的提高很有帮组，在完成10套gwd 时，已经总结出自己的方法。
首先 ，提炼题目主干，寻着作者思路来推理一遍，这一边非常重要。举例
Manatees, aquatic mammals inhabiting Florida’s rivers and coastal waters, swim close to the surface and are frequently killed in collisions with boats. To address the problem, boat traffic in manatee-populated waters is being required to maintain very low speeds. Unfortunately, manatees are unable to hear low-pitched sounds and a boat’s sound lowers in pitch as the boat slows. Therefore, this approach may in fact make things worse rather than better.
Which of the following, if true, casts most doubt on the conclusion?
A. The areas where boats would have to maintain low speeds were decided partly on the basis of manatee-population estimates and partly from numbers of reported collisions between manatees and boats.
B. Because the water hyacinth that manatees feed on grows best in water that is nearly still, water hyacinth beds can be disturbed or damaged by fast-moving boat traffic. support
C. Over the last several decades, boat traffic in Florida’s coastal waters has been increasing almost continuously and now represents the greatest threat to the endangered manatee population.
D. The sound of a boat engine generally travels much further under water than it does through the air.
E. When experimenters exposed manatees to the recorded sounds of boats moving at various speeds, the creatures were unable to discern the sounds over normal background noise.
-----目的， 保护水生动物， 推理过程 因为--- manatees -- are unable to hear lsounds lowers in pitch as the boat slows –所以限速不好 。本题直接攻击-- manatees 的ability to hear sounds ------即作者的推理依据
当然用相关性来解题跟好，本题关键信息manatees 的ability to hear sounds 只有e项包含这一关键信息。
通过这样的总结可以发现很多的套路，考试时可以迅速提炼主干 ，根据自己总结的原则解题。
个人任为og关于相关性的解释非常好。等自己的阅读能力提高后，一定要看看。
