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.
A. wild animals have less total fat than do livestock fed on grain and more of a kind

fat thought to be
C. wild animals have less total fat than that of livestock fed on grain and have more
fat of a kind thought to be
D. total fat of wild animals is less than livestock fed on grain and they have more fat
of a kind thought to be
E. 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
这题中比较的核心结构是：wild animals have less fat和 livestock have more fat，把后面那个have省略了。
类似句子:I have more pens than you（have）.

请问一下，在这个句子里，have是一个动词，当比较对象的动词一样的时候，不应该用do来代替吗？即改为than livestock do
如果是be动词，就可以省略
如果是have作助动词和情态动词+v.的时候，就省略v.， 用have或情态动词代替作者: Emma95 时间: 2016-4-3 18:51
我记得就算没有歧义，也最好不要省略。
有一个例子就是I eat faster than you.
I eat apples faster than you这个句子也需要改为I eat apples faster than you do.
就算不可能有吃苹果比吃你快这种荒诞的看法，但还是应该避免这种情况啊。我看语法笔记里面这个例子挺经典的。
