(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

请问老师，这个题目的C E 选项traveling，要如何判断它是修饰waves还是geologists呢？
有点难判断题目是不是想考就近修饰（因为先行词没有发生像老师上课说的在不同选项间置换），作题时反而容易误解为题目是想考伴随的主句"主语"（geologist）是否可以执行该动作（毕竟还有跳跃修饰。。。），请问这里"主句"该如何定义呢？谢谢

考点：
1. 单复数一致
2. inevitably = doomed，语义重复
3. 排比句，结构一致。those (lifestyles) followed by..., , lifestyles requiring...。如果不加lifestyles的话，v-ing的performer有变成people的嫌疑（就近找动作的执行者）。

考点：
1. recount后面已经有宾语了，不能再接宾语从句。
2. reputation for 表示原因，reputation of 表示从属，即reputation=of后面的内容。

考点：
1. overlook sth固定用法。没看见过 overlook that...从句，排除C。
2. 指示代词的指代问题，A&B的it指代不明。another one, such disaster才是正解。
3. v-ing serves to refer to the nearest preceding action and the performer of that action. 用condiering 而不用overlooking很重要的一点时避免歧义，前者的performer跟to rebuild一致，后者的performer有可能指the site。

官方解释排除C：
C. This choice uses the idiomatically incorrect form overlooking that. This choice is confusing also because overlooking has a physical meaning that can apply, for example, to a site but does not fit with overlooking that.

考点：
1. in spite of vs. despite
2. from...to...
3. still作为时间指示词，放在be动词之后, there are still...。

两种例外情况：
a. 表示强调时，可以将still置于句首，但常用逗号隔开。
来自牛津词典的一条解释：despite what has just been said （虽然…）还是；但；不过.
The weather was cold and wet. Still, we had a great time.
此时的用法跟but接近，用了despite后面就不能用still了。类似用了although就不能用but一样。

b. 在否定句中同样可以置于句首 = but。

选项E的In Japan放在句首更好，但E选项有两处错误，应排除。

both 不要看漏了，不要加also

A.偷换概念。原文说的是serving sizes are misleadingly small,而非卡路里
C.重复事实。原文也没有体现far more
D.重复事实。本身不是main point,而是作为论据支撑main point
E.无中生有。原文只是说实际消耗的卡路里要比标签标注的卡路里高，并不代表这种误导会导致人们消耗更多的卡路里

A 其他组织织在同一时期出现了类似的情况， 没法说明其他组织不是因为negative reaction 造成的下滑呀。 难道A就比B好么？

C 选项是不详细么？

错选 E 选项啦。 为什么不对？

只能通过后面的内容来判断brilliant的具体含义。。。。这就相当于日常说的，这个检错系统非常牛啊，我写了一篇文章，连个拼写错误都检查不出来。。。
