126. (31217-!-item-!-188;#058&006093)
Because she knew many of the leaders of colonial America and the American Revolution personally, Mercy Otis Warren was continually at or near the center of political events from 1765 to 1789, a vantage point combining with her talent for writing to make her one of the most valuable historians of the era.
(A) a vantage point combining with her talent for writing to make
(B) a vantage point, when combined with her talent for writing, that made
(C) a vantage point that combined with her talent for writing, and it made
(D) and this vantage point, which combined with her talent for writing to make
(E) and this vantage point, combined with her talent for writing, made

语法笔记的解释是:
B. When从句在此句中使用错误，when引起的从句可以作为定语从句或者状语从句。作定语从句时，要求先行词是表示时间的词或词组；作状语从句要求有动作作为合理的修饰对象。when…应该置于that之后。
E. 正确

句子结构：Because…, Mercy Otis Warren was at or near…, and this vantage point, …, made…
该句划线部分以前描述了一个客观事实，这个事实在句中能被a vantage point概括，所以该句划线部分用同位语加从句 a vantage point that…，是很好的结构，进一步对the vantage point进行解释说明。而this vantage point同样起到了概括前句事实的效果，用连词and连接两个句子。

考生一定不可看到a vantage point that…这种结构，就不假思索的认为这种结构就一定是正确的。实际上，在本书中，出现了类似a vantage point that…这种同位语结构，但是这种结构并不是正确答案的情况，已经不是第一次出现了。

我的看法:B应该是正确选项. 黄色部分其实是一个"插入语",就相当于while+过去分词的形式，只是这里while换成when。说when compared“作状语从句要求有动作作为合理的修饰对象。”我觉得这里的compared修饰对象很清楚就是前面的a vantage point。Open to discuss!

(B) a vantage point, when combined with her talent for writing, that made

(E) and this vantage point, combined with her talent for writing, made

先声明哦,以下纯属个人的猜测性~~解释:

语法上,B项是原句于句尾的同位语,E项是and连接的与原句并列的分句;逻辑含义上B项在加进when的同时,改变了原句的意思.原句并没有说vantage point使她成为 one of the most valuable historians of the era是when combined with her talent for writing.

还是没懂……有的解释说when应该放在that后，这是什么意思呢？

When 前没有任何时间词，所以不能用when ，不能根据中文意思理解，Manhattan论坛的解释是如果使用when，有两层意思
(1) sometimes the vantage point was combined with the writing and sometimes it wasn't,
and (2) it only made her valuable when it was combined with the writing talent.
that doesn't make sense.)
