标题: og16 里的一题表示对that的comparison很无力啊 [打印本页] 作者: boomshakalaka 时间: 2015-11-5 06:17 标题: og16 里的一题表示对that的comparison很无力啊 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 (that of) livestock fed on grain and more of a kind of fat thought to be good for cardiac health. 这个句子不对。其在livestock前加上that of…比较的对象是animals has less fat和that，that指代fat，而事实上比较的应该是wild animals和livestock的属性，即拥有fat的多少，所以than后面也应该用平行的句式，即主谓宾形式。正确句子为：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 livestock fed on grain and more of a kind of fat thought to be good for cardiac health.。要注意的一点：在此省略了相同的谓语和宾语（因为不会有wild animals have livestock的歧义，只要逻辑上基本成立，GMAT并不认为所有没有补出谓语动词的形式都是”ambiguities”的）。（原句不对的另外一个证据： more of a kind of fat 后面省略了(than…)，而省略的部分应该和less total fat than后面的词句是一致的，这样才能省略逻辑上看省略的必须是livestock，而不能是that of livestock，因此less total fat than后面跟的也应该是livestock。
这里是prep笔记解释，可是我我我我真的不能懂为啥事两个animal 的比较，为啥不是total fat的比较？。。。than that of 很多题不都是这样吗？为什么这题不可以呢 作者: elusive 时间: 2016-4-15 09:39
这道题有一个语法点那就是
如果比较前后两个动词一样，那么后面的那个动词是可以被省略的。
比如B：wild animals （have） less total fat than livestock fed on grain （have/do) and more of a kind of fat thought to be
后面的那个have是补出来的。因为这个have可以被省略，A就变成了不好的选项（其实A也是对的）
还有几道题也存在这个语法点
Salt deposits and moisture threaten to destroy the Mohenjo-Daro excavation in Pakistan, the site of an ancient civilization that flourished at the same time as the civilizations in the Nile delta and the river valleys of the Tigris and Euphrates.
(A) that flourished at the same time as the civilizations
(B) that had flourished at the same time as had the civilizations
(C) that flourished at the same time those had
(D) flourishing at the same time as those did
(E) flourishing at the same time as those were
这道题A选项：
that （flourished） at the same time as the civilizations （flourished/did)
还有一道题
Traffic safety officials predict that drivers will be equally likely to exceed the proposed speed limit as the current one.
A. equally likely to exceed the proposed speed limit as
B. equally likely to exceed the proposed speed limit as they are
C. equally likely that they will exceed the proposed speed limit as
D. as likely that they will exceed the proposed speed limit as
E. as likely to exceed the proposed speed limit as they are.
这道题E选项as likely （to exceed） the proposed speed limit as they are (to exceed) 作者: zoe爱猕猴桃 时间: 2017-9-27 18:50
第一个的as是表示像么作者: zoe爱猕猴桃 时间: 2017-10-1 09:11
一个疑问？
曼哈顿上写
I eat faster than you.注意与下句区别
I eat apple faster than you do
如果写成 I eat apple faster than you 按ETS的理解，从语法上就变成我吃苹果比吃你快，成了宾语比较。逻辑上显然不通。
