885 section 4-18

Under Napoleon the French were not able to organize an adequate supply system, and it was a major cause of the failure of their invasion of Russia.

(A) Under Napoleon the French were not able to organize an adequate supply system, and it

(B) The French being unable to organize an adequate supply system under Napoleon

(C) For the French under Napoleon, to be unable to organize an adequate supply system

(D) The inability of the French under Napoleon to organize an adequate supply system（D）

(E) The French inability under Napoleon of organizing an adequate supply system.

      D的 inability 肯定不如A的 not able 阿

      B C 我知道为什么错

     A 的 it 应该可以指代句子把

     即使A 不对 DE的区别 也不是很大阿 D 中 French 是人 用of 也不大合适阿

     帮帮忙  谢谢

两个方面提示我们选择D:1 it不能指代一个句子,只有一种情况,作形式主语指代that引导的从句 2 the inablility of the French a of b 结构,优于 ba结构.

另外,it 指代不清啊, 它是指前面的整件事儿还是指the supply system啊?
