请教OG71 现在分词作结果状语的问题

ljyjulia

OG71，正确的句子为：
The cameras of the Voyager II spacecraft detected six  small,previously unseen moons circling Uranus,doubling to 12 the number of satellites now known to orbit the distant planet.
这里doubling to 表示伴随结果，是否有规定动词double的逻辑主语就是主句的主语？那么这里camera做double的逻辑主语肯定是不对的，想请问，double 做伴随状语是否有规定逻辑主语就是主句的主语？

？？？？？

贱才子

首先gmac是绝对不可能这么规定的。。。。因为sc考的不是语法，而是句意表达的漂亮程度。。。任何答案都是比出来的，没有right answer。。。所以你只拿出一个答案是没办法分析的

我来帮忙把题贴全了。

The cameras of the Voyager II spacecraft detected six small, previously unseen moons circling Uranus, which doubles to twelve the number of satellites now known as orbiting the distant planet.
(A)    which doubles to twelve the number of satellites now known as orbiting
(B)    doubling to twelve the number of satellites now known to orbit
(C)    which doubles to twelve the number of satellites now known in orbit around
(D)    doubling to twelve the number of satellites now known as orbiting
(E)    which doubles to twelve the number of satellites now known that orbit

答案是B

我的理解是，现在分词这里的主语是前面一整句。是发现这个事情导致的数量增加。而which 是不能代指一整句。

Please correct me if I'm wrong.
