CR最关键的在于 读懂最后一句和首句！！！（weaken 和assumption 还有 must be true这点尤其重要！！！）
这个十分重要，看下文中到底是什么逻辑关系，举例说明
36. If the airspace around centrally located airports were restricted to commercial airliners and only those private planes equipped with radar, most of the private-plane traffic would be forced to sue outlying airfields. Such a reduction in the amount of private-plane traffic would reduce the risk of midair collision around the centrally located airports. （因为A,将导致B。答案 目前非A） The conclusion draw in the first sentence depends on which of the following assumptions? A. Outlying airfields would be as convenient as centrally located airports for most pilots of private planes. B. Most outlying airfields are not equipped to handle commercial-airline traffic. C. Most private planes that use centrally located airports are not equipped with radar. D. Commercial airliners are at greater risk of becoming involved in midair collisions than are private planes. E. A reduction in the risk of midair collision would eventually lead to increases in commercial-airline traffic.
步骤：题目最后的一句重点，reduce the risk 那么我们找原因，reduce risk 的原因装了雷达 所以答案和这个没有联系的就是无关项！
然后要注意几个小技巧： 1. 题目最后的一句话会有重点，看重点是什么。比如说save cost,那么选项一定是和省钱有关，save time 那么选项就是和时间有关。百分之百对。 2.题目最后如果说if....., so 答案选项中也出现了，if 这个政策或者方法实现了，那么一定是对的。 也就是说，答案前半句承接了原文，原文重写等于。 3. CR的技巧再说一次，就是看结果到底是怎么样的。
