急问主语比较题中的省略问题！！ - ChaseDream

一直感觉比较题是俺的短板。。。快上战场了所以比较焦虑。。请大家看下以下的例子：

A study commissioned by the Department of Agriculture showed that if calves exercise and associate with other calves，they require less medication and gain weight more quickly than those raised in confinement.

为什么those raised in confinement.的后面不加DO 呢？不是主语的比较都要把表示动作的省略补出来的吗？？

所谓要补出，是指有歧义: 分析句义，既可以合理的理解成主语比较，也可以合理的理解成宾语比较。

（你举的两道题目，无法合理的理解成比较宾语。所以没歧义）

以前的比较总结帖子都是03.04年的总结，很多说法都不太对。

1）根据逻辑意思，比较主语最合理，且无歧义，最好补出do，但是不补出不算错

2) 根据逻辑意思，比较主语最合理，但是在逻辑和语法理解成比较宾语勉强也行的时候，一定要补出 do, 取消歧义，不补算错

2. 比较分句的时态第二个比较分句时态独立，补出的助动词(除了have,had表示拥有的含义之外）不表示含义，只做时态标记

3. 比较分句的平行对称。主谓对主谓，介宾对介宾，名词对名词，不定式对不定式，副词对副词，有时分句对分句。

they require less medication and gain weight more quickly than those raised in confinement. 因为medication and weight明显不和those raised in the confinement 是一类东西所以不造成歧义是吗？

那么下面这题呢？以前问过木有人给我详细解释，如果A中光看“and more of a kind of fat they think is ”

前面的那个比较对不对呢？用DO来代替实意动词的HAVE 还是其实这个也没有歧义呢，B这样就可以了？

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.

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

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

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

还有您能不能找个有歧义的例子给我参考一下类？？

不好意思问题有点多哈~谢谢谢谢！！

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

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

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

还有您能不能找个有歧义的例子给我参考一下类？？

C的错误在于这句话的that用错了，错误地表示wild animals有livestock fed on grain的脂肪。

There is a widespread belief in the United States and Western Europe that young people have a smaller commitment to work and a career than their parents and grandparents and that the source of the change lies in the collapse of the "work ethic."

(A) a smaller commitment to work and a career than their parents and grandparents

(B) less of a commitment to work and a career than their parents and grandparents

(D) less of a commitment to work and a career than their parents and grandparents had

(E) a lessening of the commitment to work and a career that their parents and grandparents had

A就是歧义结构，可以理解成 than to their parents and grandparents,也可以理解成 than do their parents and gradparent.

I spend more time accompanying my family than my colleagues.也是歧义结构。

恩还有这种如果补出来的do 是放在前面好后面都可以的吗？像 than do their parents and gradparent (do)??

因为我下周考了现在不知道再看些什么巩固是看GWD 还是PREP...

第二个题目。

A和B都没有歧义，因为have的对象只能是 fat 而不能是livestock.

A的问题在于后半句 they没有指代对象，they think is不简洁。

C的错误在于这句话的that用错了，错误地表示wild animals有livestock fed on grain的脂肪。

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

这道题答案给的是c 我选的是b. 看了一圈帖子之后还是不够明白为什么b有问题。

我认为这里补出的that of livestock 不会引发歧义，因为原句是说清楚了total fat所以不可能歧义出wild animal身上livestock的fat 比total fat多的情况。

其次我感觉这道题还有个考点在后半句，c句补出了have 而且似乎强调了a kind thought to be 而不是fat thought to be

不补只是不好，没有任何错误。（不遵守平行原则）

所谓要补出，是指有歧义: 分析句义，既可以合理的理解成主语比较，也可以合理的理解成宾语比较。

（你举的两道题目，无法合理的理解成比较宾语。所以没歧义）

如果没有歧义，不一定要补出 do. 当然你补出了就更好。

以前的比较总结帖子都是03.04年的总结，很多说法都不太对。

比较句的考点无非三个：

1. 比较对象的一致性

1）根据逻辑意思，比较主语最合理，且无歧义，最好补出do，但是不补出不算错

2) 根据逻辑意思，比较主语最合理，但是在逻辑和语法理解成比较宾语勉强也行的时候，一定要补出 do, 取消歧义，不补算错

3）根据逻辑意思，比较宾语合理，不能补出do, 补出算错。

2. 比较分句的时态第二个比较分句时态独立，补出的助动词(除了have,had表示拥有的含义之外）不表示含义，只做时态标记

3. 比较分句的平行对称。主谓对主谓，介宾对介宾，名词对名词，不定式对不定式，副词对副词，有时分句对分句。
