答案错了吗？应该选E吧

C enhance preparation，改变了原来句子的意思，改变了原句的平行意思。

我觉得这里that不能加，因为that修饰的是一个词，及它所有属性。所以如果加that，这里的that就会表示circulation in the .....，显然 也就不是对比对象了。对比对象只能是状语，in...和in....

前后时态不一致，一个是过去的影响一个是现在的，如果你后面像E一样就默认了时态和前面是一致的

aware 这里是adj, 这个形容词结构修饰companies
形容词+宾语放在句首跟ing+宾语放在句子前的结构是一样的，因为是省略了being，而且一定要省略的 worried about和curious about都可以这么用的

B中的they指代不清楚，优先指代之前出现过的，但逻辑上是指代后面出现的companies

aware 这里是adj, 这个形容词结构在这个句子中是什么成分

i am aware that discounts are available this weekend.
--> i know that there ARE discounts, but i don't necessarily know the specifics.
i am aware of the discounts available this weekend.
--> i actually know the specifics (percentages or whatever) of the discounts.

the problem with (a) is that it says only that companies are aware "that there are connotations". in other words, literally, the companies just know that there are connotations -- in other words, that connotations (of some sort) exist -- but the companies don't necessarily know what those connotations are.

many schools do not have, or likely to have,应该是很多学校没有，或可能有
(B) nor作为连词，do not have, nor likely to have不平行, 应该在nor后面加上are, 使are likely to…和do not have构成动词结构的并列或者将likely to去掉,构成do not have, nor have的平列

请问them在这里指代新项目 还是 新项目和老项目呢？记得老师说代词只能指代一个名词

老师我想问a选项than 后面加has oil是什么用法

D
problem #1

a substance to promote... is unidiomatic.
the only context in which i can remember "a NOUN to VERB" is a context in which the NOUN is abstract in nature. for instance:
a way to produce goods
a reason to try harder
etc.
note that "substance" is a concrete item; it's not an abstraction like "way" or "reason".

注意虚拟语气，和only的位置

B选项 the money be controlled by local school districts, but it allows them to spend the money only；此处前半句省略了should，补出之后应该是 the money （should）be controlled by local school districts；后半句是but 连接两个句子，单独看的话应该是 the administration's demand that it allows them to spend the money only；此处 it 指代 demand ;them 指代 local school districts；意思是要求允许地方学校把钱花在...其实此处不用过分纠结代词，因为老师说过代词只要能指代句子中语义合理的词就是对的；

题目里有个however没有看到。本来是把这个fee放在第一次购买的时候交的，题目里的方案是把它放在salvage的时候交。

我实在是不理解这个选题方式需要断掉前提和结论间的因果关系是什么意思，我停留在这句话上很久很久

B that修饰Convention，错；应该修饰draft
C 过去完成时 错

可是主结论只有“it is likely he finally will”，后面的since一长句话都是给出的原因呐，不能把它也归于结论吧？

A →成本高也可能商用

所选取的样本并不具有代表性？是这样吗
