choice a, 介词短语放在句首用逗号隔开作状语。awareness后面跟了that引导的同位语从句，核心词是there are connotations， associated with the numbers 1 and 2 and the letters A and B作为定语修饰connotations
choice c, awareness of the numbers 1 and 2->意思变成了数字1，2所拥有的意识
choice d, aware of the connotations...句首的形容词修饰主句的主语companies, correct

A选项应该从句意上面去仔细体会，应该是意识到之后再去选择，而不是伴随着意识到去选择
BE的they it指代不清
C选项because of后面不能接句子

A/C
C，aware是形容词，comma+adj，省略be动词作状语，类似于现在/过去分词作状语的用法。
如：Content about the achievement, she smiles.
Aware that something is wrong, they stopped.
A，with+noun that不是伴随状语，with+（noun）+动词现在/过去分词才是伴随状语
A可以理解成公司和这个awareness一起choose numbers

With+名词+现在/过去分词，是独立主格。With+名词+that不是独立主格，不能做状语修饰一个句子
E.g: **With an awareness that the price in mall is too high, consumer chooses to shop online.
A do sth with B,A和B一起做某事。会让人误以为consumer choose to shop online with an wareness.

【meaning】
the problem with (a) is that it says only that companies are aware "that there ARE connotations". but the companies don't necessarily know what those connotations are.
//
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.

connotations联系 aware of n ：知道该事件的详细细节
aware that 从句：只知道存在这样一件事

B 前半句介词结尾错误，they代词指代weird，还有别的问题吗？求问！

看了三遍，A 的意思是意识到了有这个联系，联系是什么不知道，D是意识到联系，也知道这个联系。。。
因为of + noun一般都不如从句。。。误排了D留了A
另，aware of 形容词开头修饰语

i am aware that discounts are available this weekend.

i am aware of the discounts available this weekend.
--> i actually know the specifics (percentages or whatever) of the discounts.

A项有点awkard

aware形容词，做伴随状语，省略了being
aware of n ：知道该事件的详细细节
aware that 从句：只知道存在这样一件事

呃这道题虽然做对了..但是用时有点久...而且额纯粹是靠着语义做出来的...
前后两个句子，第二个是主句，第一个是用来修饰主句或者主句中某一部分的从句。
很显然，句子要表明的是company be aware of了啥啥啥，紧接着company choose了啥啥啥
重点排A选项，with出现的很奇怪，仿佛是在所company choose的这个过程伴随（with）了一个啥啥啥
其他几个选项要么指代不清 要么代词模糊

这道题挺模糊的，没有非常明确的考点，排除点Manhattan也没提，prep07解释如下：
①on account of/because of/despite(in despite of)/as a result of 等介词短语后只跟简单的名词短语，若气候跟的是动名词或名词所有格+动名词短语（sb's doing）,以及名词短语后用现在分词做modifier，应改为because、although等连词所引导的从句→由此排除C
②pronoun：忘记去分析pronoun了， 这是个比较常考但又常被我忽略，觉得难以判断的考点，以后要多加注意→可以排除E，因为it指代错误；但我觉得不能因此排除B，其中的they从逻辑意义上讲只能指代company，这是个很模糊的判断点。暂且不表
剩下A与D，都做整个句子的修饰语，我当时以为形容词不能直接做modifier，至少应该以 bing aware of.....才对所以排除了D。
总而言之，这道题，有毒。但形容词做modifier这个知识点要补。

逻辑上两个小句之间是因果关系，前面小句的逻辑主语是companies，ABCE均无法表达出是companies意识到，D是伴随状语表原因，aware前省略了Being。

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.

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.

aware of 置于句首修饰companies
aware 这里是adj, 这个形容词结构修饰companies
形容词+宾语放在句首 和 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是因为(有have )所以咋样
D是因为aware
逻辑上因为知道才做，不是有，才做，因为有不知道，也不会做。。。

A:知道他们有connotation(内涵),D：知道他们的内涵（老炮儿）

A with an awareness that + 同位语从句，有一个意识（1&2, a&b之间有联系）
D aware of connotations of .. of作定语，表示意识到（1&2，a&b）的联系

AD两个选项，整体上都做状语。

论元核心 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.
