补充166

166 During the 1980s it became clear that soliciting private funds was far more efficient for environmentalists who sought financial aid than to go to state or federal agencies.

(A) that soliciting private funds was far more efficient for environmentalists who sought financial aid

(B) that for environmentalists who sought financial aid, it was far more efficient to solicit private funds

(C) that for environmentalists seeking financial aid, private organizations were far more efficient to go to

(D) for environmentalists seeking financial aid, going to private organizations was far more efficient（B）

(E) for environmentalists who sought financial aid, private organizations were far more efficient

我想知道的是:此处的两个IT 都为形式主语吗?

顶一下

是的，两个都为形式主语，

对于c选项，我尝试着解释一下，对environmentalist是who还是seeking的问题，在白勇的语法书中写的是这样的，后面加宾语从句是代表一次性的行为，对于加ing是强调的一种性质或者是无数次的，因此显然用who来修饰比较好．另外，你有没有发现c选项掉了一个词么？solicit没有和其他重复什么的所以改变会影响句子．．

当我再看一下句子的时候～觉得c选项表达不清楚～

欢迎讨论～因为当时偶做对了．．所以想得不是很多．．．．．

我觉得两个it都是形式主语：

第一个it是指“solicit private funds is more efficient than to go to state or federal agencies”这件实事。

第二个it是指“solicit private funds ”

不知道对不对？
