(A) Polio, although it is eradicated in the United States, it continues elsewhere and is able to be (B) Polio, although eradicated in the United States, it still continues elsewhere and can be (C) Although still continuing elsewhere, polio has been eradicated in the United States and could be (D) Although having been eradicated in the United States, polio still continues elsewhere and is capable of being (E) Although eradicated in the United States, polio continues elsewhere and could be
我想问一下，D中的having been eradicated作为modifier有问题吗？在一个论坛上看到一个说法： Having + past participle is used to indicate an action that: -- is completed before the primary action attributed to the modified noun -- provides context for the primary action attributed to the modified noun 那这里说eradicated发生在continues和be brought前，应该也make sense吧，请牛牛指教！作者: MiaZhang 时间: 2012-12-4 19:44
这里的问题在于although的省略。状语从句省略的部分必须是主句主语+be动词作者: DesmondWang 时间: 2012-12-4 20:42
谢谢，什么叫although的省略，能详细说一下吗？作者: MiaZhang 时间: 2012-12-4 21:39
although引导状语从句，这里就是状语从句的省略问题啊~~状语从句引导词后面句子省略是有条件的，主语必须是主句主语，动词必须是be。主语和be同省同留作者: DesmondWang 时间: 2012-12-4 21:52
oh,了解了，太谢谢了，真厉害！ 所以D还原的话就变成although polio is having been eradicated...这个样子了是吧作者: MiaZhang 时间: 2012-12-4 21:59
嗯，是的呢~这样的话句意就不合理了作者: DesmondWang 时间: 2012-12-4 22:03
谢谢，你好牛啊，呵呵！
