OG10-177的一句解释有疑问

177.
            So poorly educated and trained are many young recruits to the United States work force that many business executives fear this country will lose its economic preeminence.

(A) So poorly educated and trained are many young recruits to the United States work force that

(B) As poorly educated and trained as many young recruits to the United States work force are,

(C) Because of many young recruits to the United States work force who are so poorly educated and trained,

(D) That many young recruits to the United States work force are so poorly educated and trained is why

(E) Many young recruits to the United States work force who are so poorly educated and trained explains why

A, the best choice, uses the idiomatic form So X that Y to establish a cause/effect relationship between clauses X and Y. In B, the subject of the as... as clause (young recruits) should be the subject of the main clause as well (e.g., they).
            Furthermore, main clauses following concessive clauses must express a contrasting notion: for example, “As ill-prepared as they are, they nevertheless find good jobs.” C offers a wordy, convoluted because clause. In D, the sentence form X is why is unidiomatic (X is the reason why would be idiomatic but needlessly wordy and awkward). E exhibits subject-verb disagreement: young recruits... explains why.

B选项没有表达出cause/effect的意思，另外，B选项中的as as没有表示contrasting，这两点我都非常认同；

可是解释中的In B, the subject of the as... as clause (young recruits) should be the subject of the main clause as well (e.g., they).

是说as as中的主语应该是主句的主语么？为什么要求主语这方面的一致呢？

不是有很多例子用as as比较前后两个不同的主体么？

假如抛开其他的错误，单独看as as的用法，本题说

as poorly educated and trained as many recruits…are, many executives fear…难道不可以么？

请同学们帮忙解答，谢谢；

按照B的语法结构，as as的主语当然就是主语主语，are是谓语，之前as as表达的必须是主语。这里并非as as的要求。

这个句子结构你已经写出来了，逗号前后各自有主谓，中间一个逗号，没有任何连接词，可以判run-on sentence了。答案应该是不可以。

A用的挺好，意思表达的很清晰，重点也突出-倒装。

一般的结构写出来就是：Many recruits。。are so poorly educated and trained that many executives fear....

这个就没有远句的强调 so poorly educated and trained

感谢uneverknowba的解释，我看懂了，再追问一下，如果非要在B上面修改的话，是不是这样就对了，

Being as poorly educated and trained as many recruits…are, many executives fear…

不同意以上的意见, 这道题要从逻辑意思着手:

意思是说年轻的雇员如此缺少教育及培训的这个现象, 使得管理者非常担心

这里不是比较, 不是说雇员与管理者一样的缺少教育..., 而是" 如此... 以至于" 的意思!

所以即使楼上的把b 改成:

Being as poorly educated and trained as many recruits…are, many executives fear…

仍然是个比较关系, 属于逻辑关系错误!

另外补充: as...as.. 不一定是说要主语相同, 但是这里的比较: as poorly educated and trained as many recruits are, many executives  在第一个as后面没有出现主语, 所以给人的印象是省略了主语, 从而是将主句的主语与recruits来比较

不知道说清楚没有

感谢dingxiang的解答，说的很清楚，很到位；
