Experts estimate that ten times as much petroleum exists in sources like tar sands, heavy oil, and perhaps even in shale than in conventional reservoirs.

    

A. sources like tar sands, heavy oil, and perhaps even in shale than

    

B. sources like tar sands, heavy oil, and perhaps even in shale than are

    

C. such sources as tar sands, heavy oil, and perhaps even in shale as are

    

D. such sources as tar sands, heavy oil, and perhaps even shale as

    

E. such sources as tar sands, heavy oil, and perhaps even shale than

    

这个题目首先因为举例要用such as ，我排除了A和B，然后as，，，as，要成对出现，并且比较对象要对等，但是我选了C，担安是D，有没有人能够帮我解释一下，C怎么不对？谢谢。

C are 无对等成分
petroleum exists as in sources as petroleum exists in sources
可简化为介词短语比较

as in sources as in conventional reservoirs

是不是C当中那个are一看就很傻，明显是错误答案？只有当前面出现Be动词的时候，比较对象对等后面才有可能补出这个东西是吧？

She was less successful after she had emigrated to New York compared to her native Germany, photographer Lotte Jacobi nevertheless earned a small group of discerning admirers, and her photographs were eventually exhibited in prestigious galleries across the United States.

    

A. She was less successful after she had emigrated to New York compared to

    

B. Being less successful after she had emigrated to New York as compared to

    

C. Less successful after she emigrated to New York than she had been in

    

D. Although she was less successful after emigrating to New York when compared to

    

E. She had been less successful after emigrating to New York than in

大侠，我可不可以再问一个题目，这题我纠结了半天选C还是选D，最终还是搞错了我选了D，虽然我当时觉得D比较罗嗦，但是看到C那个时态貌似不太对，我为了忠实原文，又一次被阴了。

C Less successful after she emigrated to New York than she had been in her native Germany
其实是一个省略
She was less successful after she emigrated to New York that she had been in her native Germany
省略掉 she was
成为形容词短语在居首，修饰主语 photographer Lotte Jacobi

ilhht

但是after 后面是不是一定要加ing形式或者是句子，如果C变成after emigrated就错了是吧

同意

引用白勇语法
before/after+doing sth, + 句子 doing sth. 的逻辑主语等于句子主语

when/while/if /unless/although/even though/even if + 形容词短语/-ing 分词短语/-ed 分词短语 （逻辑主语等于句子主语）

thank you so much songlovergt!!

我觉得

不能说 after之后加 ed分词就错了。连词+分词的本质是省略结构。还原回去是 conj+link verb+participle

连词 after之后加省略结构被动 没什么问题。但问题是emigrate这个词本来就有主动表达的形式，去用被动很奇怪。比如即使不省略 这样用也很奇怪：

After he was emigrated to blablabla...

因为本来就不对，你把 he was省掉就更不对。

after +ed + 名词，可以理解。ed分词可以修饰其后名词。

但 after后只加ed分词，我不太确定，好像见过，不敢妄言

LS能否举个例子。
