[求助than后面该是什么结构
有这样一个句子：It is clear that the dog has a much greater proportion of its brain devoted to smell than is the case with humans.这句话的释义是：很明显，狗大脑中嗅觉部分所占的比例要比人多的多 ——选自《2006年6月英语等级考试四级真题》（老版）问题是“than"后面的"is the case with humans"是什么结构？是不是省略了什么词？[此贴子已经被IsaacZ于2006-12-2 7:53:18编辑过] than后是一个倒装结构，相当于“the case with humans is”，这种倒装结构只用于比较主语的时候，当然，不倒装也可。详情见下：发信人: CNLAS (Ich gewinne bestimmt……), 信区: EnglishBar 标 题: Re: [求助]有关more than的语法问题 发信站: 北邮人论坛 (Thu Nov 23 14:08:28 2006), 站内4. comparatives Cheetahs run faster than do antelopes. You speak Chinese better than do I. Jessica is more interested in Computer Science than is Benjamin. Inversion is optional. Used with all verbs. This form of inversion is common on the TOEFL, GMAT, and GRE. We normally only have inversion here if we are comparing subjects of the verb, not objects. For example, in the following two sentences, we are comparing objects, carrots and potatoes, not the subject I : I like carrots more than I do potatoes. --- correct I like carrots more than do I like potatoes. ---wrong Now, in this sentence, we are comparing subjects, I and my friend Carl: I like carrots more than does my friend Carl. ---correct<div></div> 谢谢站长！
