OG解释：
A, the best choice,uses the idiomatic form So X that Y to establisha cause/effect relationship between clauses Xand 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, mainclauses following concessive clauses must express a contrasting notion: forexample, “As ill-prepared as they are, they nevertheless find good jobs.” Coffers a wordy, convoluted becauseclause. In D, the sentence form X is why is unidiomatic (X is the reason why would be idiomaticbut needlessly wordy and awkward).E exhibits subject-verb disagreement: youngrecruits... explains why.


对红色的解释不理解。我们平常不是经常说  this is why... that is why... 这样的句子的么？？为什么OG说 ""X is why" 这个是unidiomatic的呢？？？

我主要觉得是D不是常用法。。。太累赘了，主语等于是That之后的一大堆。。。 你说的that is why, this is why，我觉得因为that/this指代让句子很清晰。。。

这题考点是so。。。that。。。。，A确实比D清晰许多。。。

这就是gmat语法了啊，要把日常语法和gmat语法的概念完全划清。

对于gmat来说，so X that Y 能用两个词表达清晰的关系，你用that is why三个词来表达就是啰嗦。

但主要还是unidiomatic，说明gmat不承认这种日常语法。
