There are hopeful signs that we are shifting away from our heavy reliance on fossil fuels:  more than ten times as much energy is generated through wind power now than it was in 1990.



(A) generated through wind power now than it was

(B) generated through wind power now as it was

(C) generated through wind power now as was the case

(D) now generated through wind power as it was

(E) now generated through wind power than was the case

oma：C

这道题目我真的是觉得很晕啊。我一直觉得B没有错误，it指代的是energy……是说像这种被动的，如果像B那么说一定要说it was generated in1990么？真是不清楚……我已经被这些比较搞的晕菜了！高人啊！指点啊！感谢啊！！！！！！

唉，自己顶一下……高人啊！请现身啊！

它比的是generate动态的过程,而不是单单energy,而as be the case中的as可以指代整个句子的,但it显然不可以~

哦……原来如此，谢谢谢谢~~~~~

我认为it指代错误。因为1990的energy和现在的energy不是同一个energy，所以不能用it指代。个人观点。
