谢谢版主的回复，

那么句子：

Aware of the connotations of the numbers 1 and 2 and the letters A and B, companies conducting consumer taste tests of foods or beverages typically choose numbers such as 697 or 483 to label the products.

 句子结构

 Aware(adj) + of + n, companies 。。。 typically choose numbers 。。。 to label the products。

一个adj修饰n 一般格式： adj + n,

多个adj 修饰n一般格式： adj 1, adj2 and adj + n

1. 虽然我也没有见到过aware 直接修饰n 的情况，这里aware 没有直接修饰companies, 为什么加（of + n）修饰company?

请举例子。谢谢，有点无法接受这个结构。

2 通常 be + aware of 出现，是不是这里省略be ?

(Be ) aware of + n....., companies ....typically choose numbers ... to label the products.

如果是，(Be) aware of + n..结构的逻辑主语是companies?

 谢谢。

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

A选项的there are就是省略都不影响句子结构的，可见是多余的

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

做状语啊
