if the action is in the present, then you use "known to VERB"; if the action is in the past, then you use "known to have VERBed".

句子合理重心应该是结论为主句，达成结论的动作过程为辅

if you open a sentence with "like X, ..." then the following two things must be true:
1 * X is a noun (or something else that can function as a noun, such as a gerund, noun-type phrase, etc). in other words, X should not be a clause
2 * you INTEND a COMPARISON between X and the SUBJECT of the following sentence.

if these 2 things are not true, you can't use "like".

绝大部分女性 肯定是复数

动作carry和后面几个动作并不平行。这个句子的逻辑关系是，“Carry”这个动 作没有参加“compared”，而是自成一个层次，而另外四个动词是“compared”的项目，它们另外组成 了一连串的动词平行结构。故而A中的第一个“and”是必要的。 2

没有that 前面整句话和后面平行了，make no sense

it would be two... it 指代没错 也不对 一个公司是两个公司？
break up into

capable of doing
capability to do
ability/ability to do

a it没有指代
b compared with German 前面没有任何平行
d the energy不知道哪里来的；nuclear power in german可理解为itself in German
e 前面的错误都有

multistory building我还以为是很多故事的建筑。。。

as large or larger than×
动词分词做后置定语

动词与形容词同时存在时候，优先选动词

substitution：置换。substitute：替代品
C：this implies that the fertilizers themselves are "substitutions". that doesn't make sense; a "substitution" is actually the process of substituting one thing for another, not one of the things themselves. 改成substitutes就对

you don't say both "as big as..." and "long" in the same sentence. you can use only one of these words, both of which express the same idea (i.e., length or size).

include不能描述一个集合中的所有元素

1.to mass-produce不定式表示动作趋势，而mass-produce goods是已经发生的事实，所以用名词the mass production of manufactured goods更为恰当
2 .make sth. adj结构中如果sth.过长，可以宾语导致：make adj. sth.。

这道题徘徊了一下 a和d ，一开始感觉这俩谁也不太对。 还是选错了。没有仔细看。

E选项中说的是many，是绝对数值；文本中只能推出most，是相对比值。绝对数和相对数应该不能互推吧？

show sth to be, show sth as……，show的对象都是物体，to be/as作sth的补语，不是discoveries 显示了一个物体，而是discoveries show that +一件事情

C: tour bus一般接送乘客的时间少于在P处接送乘客时间的1/4。那么联系上文，可能更多的时间bus都在P处idle？？？
ABD无关可以排除。对比CE，E只是原原本本地解释了上文的P被damage的原因。Buses have no place to park while their passengers are visiting in P. 不涉及任何有关解决方案：新增parking能解决buses的idle问题，所以其实E也是无关选项。
