SAT OG 语法题

As an undergraduate at Rutgers University, Paul Robeson developed a serious interest in drama. ....
这是比较常见的形式，as ...., sb. do sth. 作为一名学生，paul。。。

(D) Paul Robeson developed a serious interest in drama, having led him eventually to a
这里现在分词having led一般隐含着表示动作的发出者是前面句子的主语paul，例如 Tom speaks more loudly, making him heard by the others. 现在分词making 是Tom 做了某事，令他人能听到自己，make的动作发出者是前面的人
同理Paul Robeson developed a serious interest in drama, having led him eventually to a
这里也暗含着having led中lead这一动作的发出者是paul，但是事实上是他的兴趣，引导他走向.....， lead的发出者应该是the interest in drama，不是人。

(E) Where he developed a serious interest in drama, paul Robeson, as a result, eventually went on to
这里的where引导定语从句，那么前面应该是表示一个地点的，应该是At Rutgers University, where he developed a serious interest in drama, paul Robeson, as a result, eventually went on to

而题目的as a student at ......是状语，一般都是以As....., sb. do sth.这形式出现的~

D中having这个非谓语的主语被偷换成了Paul Robeson，本应为interest
E偷换概念，改变了语义，原义强调的是form an interest，然后interest 做诱因，才有了distinguished career.
