如果已经以所有格形式存在的名词，在后面的代词中无法指代改名次，如E

学会分清两个动作到底是并列还是一个导致另一个，显然是因为wide了range才导致letting 员工能选择最重要的

ultimate goal表示最终的的目标，是有一个过程而不是直接达到的因此用of doing而不是to do 因此BCD都不对
reduce的是顾客的数量而不是reduce顾客 排出A

D：in order to做目的状语修饰stay，stay的目的是collect；E：that定语从句修饰day，他们被安排collect这一天。E明显句意不合逻辑。

B，提到support，更接近文意

A提到了property right，但definition是无关信息，不可以选

原句没有因果关系

根据原文可知study这个动作在之前就存在，只不过是到了1900年开始seriously。属于状态的持续而不是转变，故用doing而不是to do

错选E: ,each had been connected 不是独立主格，他是一个完整句，两个完整句缺乏连词，e错
, each connected 才是独立主格

题目结论是，移除报警亭，用私人电话可以 1.减少乱报火警 2.私人电话不会妨碍报警能力
所以加强从这两个方面切入。
答案A 直接就说，因为可以追踪可以减少乱报火警。

C 只是提及可以给到更多的信息，但是不支持手机不会妨碍报警能力。至多也是说明手机让报警变得更好。等于是锦上添花。

D 选项看起来就有点无关了，因为和想要加强方向的结论都没直接关系。

逻辑题做多了，感觉不能每道题都套方法论，还是得回归题目本身，什么评估这，评估那的，就得看透题目。

The same to A as to B 惯用语，错选了C，但C里的it不能指代一件事情（natural phenomena would appear to someone 这件事情）

(b) actually doesn't have correct parallelism.
the "the" in front of clearing indicates that it's a noun form. (there's no such word as clearage, or clearation, or whatever, so this is the best noun form you're going to get here.)
to be parallel to the clearing, you need another dedicated noun form. here, that's the removal.

From RON:

removal is better.
there are a bunch of words like these, with specific noun forms that, simply because they exist, are considered better than the corresponding gerund (-ing) forms. notable among this class of nouns are the '-al' forms, like removal, betrayal, etc.

unfortunately, there are no general tips of the form you're soliciting; such are the joys of the english language. the closest i can get to a general rule is this: if a special noun form exists, use it. if not, use the -ing form.
as for your examples above, you wouldn't want 'removing' because removal is a better substitute. clearing, though, is fine because there's no specially designated noun form for that one.

S说有优势 R说无优势----讨论是否有优势

句子主干是slackening is inflluenced less by gov reg than by。。所以肯定有by,排除ab，cde区别在于end，这部分没化线，但线应该划到a period。c的by ending a period是一个doing动作，结束无发出者，而且中心词不对。剩的ce区别在于end的实然和将然状态，C正解的coming to an end 是一个状态，动态（变化中）符合产量增长放缓（变化动态），更贴文意。 增长放缓的原因是农业高速增长期要来了，而不是已经来了（所以不是end).关键破题第一部在于，less ..than比较平行结构。 【本来我还不清楚，写完解析发现自己变
清楚了。。}

这题用both...and这种硬性条件就可以把答案选出来了～

如果把 B 中第一句换成D的 there is continuous coastal erosion，仍旧对吗？？即：there is continuous coastal erosion，not just in calamitous bursts such as hurricanes, has

这都能做错....

P的意思是因为法官不做lecture，所以这个ban没用。所以p是用了现在的法官！！而不是以后的法官！！！

请问E选项，being based on 结构是表示什么意思？该怎么判断呢？

请问D和E选项，伴随状语shifting的逻辑主语是不是streams？还是geologists？我觉得应该是宾语从句中的streams
