as引出的倒装结构（如as does sb, as does sth等）

回答如下：

以上属于修饰倒装，处于文学表达效果上的需要尤其是主语很长/保持句子平衡而使用倒装。

中文意思：将被选择的道路会通向一个未知结果，就像人生中所作得的任何选择一样.（是无法提前知道所做的选择或者选择道路最终会导致一个什么结果）

【1】as引导的让步状语从句中的倒装：

在as引导的让步状语从句中，位于句首的可以是形容词、名词、副词，还可以是谓语动词的一部分，从而形成从句的部分倒装。

Tired as he was, he continued the work.

虽然他累了，但是仍然继续工作。

【2】方式状语从句中的倒装

as引导的方式状语从句一般为正常语序，但是，如果主语比谓语长，可将谓语动词置于主语之前，形成完全倒装

倒状结构为： 主句+  as+（助动词/系动词）+主语（备注：这里助动词是代替前面主句谓语动词形式,如果主句谓语是行为动词的一般过去式就用did代替,如果主句谓语动词时行为动词三人称单数，从句倒装则用does代替.）

He believed，as did all his family，that the king was the supreme lord.

他和他全家人一样，都认为国王是至高无上的君主。

She looks forward,as does her secretary,to the completion of the building.    她像她的秘书那样盼望工程竣工
