(D)   still far less of the energyconsumed in the United States has been accounted for by natural gas as by oil

(E)    still far less of the energyconsumed in the United States has been accounted for by natural gas than hasoil

正确答案是D

两道题的比较结构的后半部分分别是【than has oil】和【 as do humans and other warm-blooded animals】 为啥has和do都跑前面去了？我自己觉得应该是【than oil has】

比较结构倒装不倒装都可以。很多时候倒装的题目是因为比较结构后面的名词要被修饰所以把动词提前，但是你的两道题没有修饰也倒装，没有什么问题。

这两道题考点不是倒装，

第一题因为C里有“ less....as".这个结构不对，只有less... than 或者as... as.所以A对。

第二道题里“has”和“do”对应 都是动词，但是“can”不是。

怎么又是你...我记得昨天晚上还给你发了两个链接.......虽然我今天than比较级也发现不会做，than这个结构总是刷新我对gmat下限的认知......
第二句的as就是so的意思，as do I= so do I, 这里就是so do humans and other warm-blooded animals， 倒装结构嘛，再反一反就行了

很多倒装，是防止头重脚轻或虚拟语气或修饰歧义，建议去看下杨鹏长难句第一章基础知识，就明白这类了。

你这比较里的倒桩，是 倒不倒都无所谓的。
