28.   (26003-!-item-!-188;#058&002229)

Polio, although it is eradicated in the United States, it continues elsewhere and is able to be brought into the country by visitors.

(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

这道题的答案是E，可是E选项中  Although 在OG上面说因为是连词，必须引导从句，必须有主谓。所以如果Although 后面的内容理解成分词的话，

与OG的说明不符吧？

如果是住所以主谓必须齐全，而且这道题主句和从句的动词并不一致，为何第一句没有谓语那？

谢谢大家了！！！

 楼主，E选项用的是省略。状语从句的省略：满足下列三个条件可以进行状语从句的省略（1）although,even though, when, unlike, unless, if 等连词的存在；（2）从句要有be，（3）从句主语与被修饰的主句主语是一致的。在这种情况下，状语从句中的从句主语和be一起被省略。

所以选项E是有主语的，主语就是polio,如果非要把前一句补全的话就是：altough polio is been eradicated in the united States, polio.....
