标题: 一道考比较的语法题

According to recent studies comparing the nutritional value of meat from wild animals and meat from domesticated animals, wild animals have less total fat than do livestock fed on grain and more of a kind of fat they think is good for cardiac health.

 

  1. wild animals have less total fat than do livestock fed on grain and more of a kind of fat they think is

  2. wild animals have less total fat than livestock fed on grain and more of a kind of fat thought to be

  3. wild animals have less total fat than that of livestock fed on grain and have more fat of a kind thought to be

  4. total fat of wild animals is less than livestock fed on grain and they have more fat of a kind thought to be

  5. total fat is less in wild animals than that of livestock fed on grain and more of their fat is of a kind they think is   Answer: B

既然说than连接的比较两边应该对称,那么B选项应该是than do livestock fed on grain...,do 对应前半部分的wild animals have啊?

请高手解答!!

说明他们认为在意思没有什么ambiguity的时候,do是可以省略的,你总不可能把它误解成野猪身上的脂肪比野猪身上的家猪少吧。对称是比较的双方对称,例如,i eat more mean than rachel. 不一定要加do的。如果是i eat more chicken than eagle does. 就不应该省,因为人也可以吃老鹰肉。

fed是feed的被动状态修饰livestock
