问OG11_85 关于it 指代动名词

dontwannalos

85.Dirt roads may evoke the bucolic simplicity of another century, but financially strained townships point out that “dirt roads cost twice as much as maintaining paved roads.”
(B) dirt roads cost twice as much to maintain as paved roads do
(D) maintaining dirt roads costs twice as much as it does for paved roads
想问选项D为啥错误呢？it指代maintianing啊，官方解释却说“It has no referent"。

可是对比OG11_73题：
According to a recent poll, owning and living in a freestanding house on its own land is still a goal of a majority of young adults, ”like that of earlier generations.“
(E) as it was of earlier generations
也是用it来指代owning and living的啊？望指教

个人见解：
[OG11-Q85] 以逻辑意思为先. 这里的比较是主语的比较(dirt roads vs. paved roads) . 且比较结构要平行，既然平行，这个do就要补出以免歧义。 D选项首先就不平行 (分词短语和句子不构成平行)，是可以直接排除的。

[OG11-Q73] OG解释的很清楚啊。it是指代"owing ....... on its own land", 补全了就是: as owing ....... on its own land was (a goal) of earlier generations.

我的理解it应该是指代 maintaining dirt roads,名词短语作为一个整体。相应的it也应该是指代owning and living in a freestanding house on its own land。

其实85题it 应该放maintaining paved roads的意思，但实际上it 没有指代任何意思

其实我觉得就算是85题中的it是指代maintaining paved roads,就相当于是x costs twice

as x does for *****，这样的句子结构是很奇怪的。

而73题中的it是指代 owning and living in a freestanding house on its own land 这样

的一种愿望，是没问题的
