CR难题的结构特点

FlyingC2

刚做了8道prep2012 pack1的8道难题，错了4道。
medium和easy难度我掌握的不错，一到难题就不行，
我于是研究了一下Manhattan prep的逻辑结构，就6-7种。
然后发现了自己的弱点

CR逻辑结构
常见
1. conclusion - premise.
2. background - premise - conclusion （略长，背景一定在最前边，紧跟的是premise）
3. premise - premise.
有intermediate concludsion都绕，但少见
4. premise - intermediate conclusion - final conclusion
5. final conclusion - premise - premise - intermediate conclusion
有counterpoint的都难 (篇幅必须长，不然写不下)
6. conunterpoint - premise - premise - conclusion
7. conunterpoint - conclusion - premise
8. background - conunterpoint - premise - conclusion
我错的绝大部分是带有countpoint的题目。
这种题目思路要绕个弯，脑子清醒的时候做得吃力，不清醒时基本都错
各位有什么办法解难题，尤其是想上750+的话

这是我前两天做题发现的两道难题，现在都明白了。
有时觉得题干问法特别绕，比如055
Correctly measuring the productivity of service workers is complex. Consider, for example, postal workers: they are often said to be more productive if more letters are delivered per postal worker. But is this really true? What if more letters are lost or delayed per worker at the same time that more are delivered?
The objection implied above to the productivity measure described is based on doubts about the truth of which of the following statements?
这题看着特像weaken，但在问assumption。

有时候是读不清关系，比如052
Consumer advocate: It is generally true, at least in this state, that lawyers who advertise a specific service charge less for that service than lawyers who do not advertise. It is also true that each time restrictions on the advertising of legal services have been eliminated, the number of lawyers advertising their services has increased and legal costs to consumers have declined in consequence. However, eliminating the state requirement that legal advertisements must specify fees for specific services would almost certainly increase rather than further reduce consumers’ legal costs. Lawyers would no longer have an incentive to lower their fees when they begin advertising and if no longer required to specify fee arrangements, many lawyers who now advertise would increase their fees.
