GWD29-24没人问过

刚发现这个话题顶层的Question不是我刚讨论的那个....我看成楼上上上同学问的Question了

以下贴子我觉得基本算是ultimate solution了：

读后感：
ambiguous与否，句意说了算，别“抬杠”
B挺明显的主语和主语比较，有对称美。
似乎没人说C那个"have morefat of a kind"的问题，我觉得这个比较awkward

正确答案是B

选项分析：

A. they没有指代对象；

B Correct. 是主语部分wild animals 和 livestock fed on grain在比较。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”；"less X and more Y"是 idiom correctly.

C. 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；

In addition to having more protein -than wheat does, the protein in rice is higher quality than that in wheat, with more of the amino acids essential to the human diet.

(A)the protein in rice is higher quality than that in



(B)rice has protein of higher quality than that in
(C)the protein in rice is higher in quality than it is in



(D)rice protein is higher in quality than it is in



(E)rice has a protein higher in quality than   (b)

题目最后with more of the amino acids essential to the human diet,中with的逻辑主语应该是rice而非the protein，因此，排除选项C。

 我觉得这道题用这个例子来解释再好不过了。这个例子里面包含了： having more protein -than wheat does  正如本题B里面的 wild animals have less total fat than livestock  所以B是正确的
又包含了    rice has protein of higher quality than that in                  正如本题C选项里面的wild animals have less total fat than that of livestock 乍看是一样的 实际上大不相同。 要是本题C选项换成 wild animals have total fat less than that of livestock 就正确了。 就这么一点点的区别。意思上的区别。比较对象的区别。


本题C选项里面是 比较HAVE LESS FAT 不能用THAT 相当于是比较主谓宾 后面省略主谓

而改成 total fat less than that of livestock 就是在比较宾语了。所以要用THAT 不然就变成了 wild animals have total fat less than livestock。 就不MAKE SENSE了个人愚见  求指点！！！

vote for C,句子层次是这样的：

According to recent studies comparing the nutritional value of meat from wild animals and meat from domesticated animals,wild animals{have [lesstotal fatthanthat of(livestockfed on grain)]and have more[fat of(a kind thought to be good for cardiac health)]}.

又是一个长达7年的讨论么..  prep08-218的补充说明貌似是本版的浓缩版，但是那里面为什么说是未完稿？


我选B， 原因如下


1，C.    wild animals have less total fat than that of livestock fed...  我觉得对比的对象没有错，确实是 fat 与 fat of livestock对比，但是从句意上看这2个fat都是归属于wild animals，即animals have both of them
    C补全之后为： wild animals have less total fat than (wild animal have) that of livestock ...
    如 I have more apples than (I have) bananas.
    对于前面提到的protein in rice的问题， 我觉得正解B选项可以这样看：
    B. rice has protein (of higher quality than that in)... 括号中内容的为protein的定语，不参与主句SVO结构，所以不会有rice has that in wheat的问题。 而本题的C就不一样了，如72楼alicezyk前辈所说：    “wild animals have total fat less than that of livestock 就正确了。 就这么一点点的区别。意思上的区别。比较对象的区别。”


2, 关于and前后结构的平行。 我同意48楼singdeath前辈的看法：
“B中的and前后不存在歧义。因为即使没有have来暗示并列比较，还有less total fat和more of a kind来暗示两个并列的比较，说明的是fat的量和fat的种类/性质在野生和家养的动物之间比较。我觉得很清楚，没有歧义。”
    完全可以理解成and后面省略谓语have的形式, 即
        B. wild animals have less total fat than  livestock fed on grain and (have) more of a kind of fat thought to be
    另一个比较扯淡的理由，如果把讨论的范围一直限定在  livestock fed on grain and more of a kind of fat 这个范围， 很容易就会看成这2者在并列，但是当整句通读下来的时候，反正我是感觉不到livestock跟and后面的在平行，不知各位NN如何解释。


以上为个人意见+引用前辈观点，有砖请轻拍，还有别打脸...


我的问题是
1， 如4楼littledou前辈所说，为什么do不这么放: wild animals have less total fat than DO live stock (fed on grain) and...
补出的谓语以倒桩的形式放前面，貌似OG上也出现过类似的句子，那么为什么这里不这么做而是直接省略？把补出的谓语动词倒桩有什么要求么？
2， 一个在这个帖子前面出现过的，几乎被所有人都忽略的问题：
B.wild animals have less total fat than livestock fed on grain and more of a kind of 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
这个more of a kind 和 more fat of a kind有什么区别？


希望在考试前有人能挖到这个坟，不然考试时碰到就妥妥的跪了。

我在这里给这个帖子下个结论吧。
实际上根本的误区在于究竟哪些是比较主语还是比较宾语。

Jim ate more than Peter（did）. 毫无疑问这句句子在这里是比较主语。由于没有宾语，不会造成歧义，所以没有必要补出谓语。翻成中文是Jim吃得比Pete吃得多
Jim ate more apples than Peter did. 与上一句句子比较，尽管多出了宾语，仍然不改变比较主语这一本质——即Jim吃得比Peter吃得多。

再来看一句，Jim has more apples than Peter. 相信没有人会理解成Jim有的苹果比Jim有的Peter多（正常人听这句话应该会在Peter后面脑补does）。Jim有得比Peter有得多，这是两个主语之间的比较。

Jim has apples bigger than those of Peter. 与上面两句不同，此句为宾语之间比较。翻成中文应该是Jim有比peter的苹果更大的苹果。显然是两者苹果之间的大小比较。

接下来我们再来看对两个非常经典的具体应用
Wild animals have less total fat than that of livestock.
如果能理解前面所做的铺垫，这里就不难看出此地的比较对象是Wild animal和that（fat）of livestock。显然是不符合逻辑的。
如果硬要改写的话，应该写出Wild animals have  total fat less than that of livestock.因为这样改写以后就由主语的比较化为宾语的比较。
而选项B， Wild animals have less total fat than livestock （does）.这样就变成了野生动物和家畜两个主语之间的比较。这里助动词可以不加（选项a倒是加了，但是they没有指代，显然是跑来捣乱的），因为在SC中逻辑错误是优先于歧义的——两害相权取其轻。

Rice has protein of higher quality than that in wheat.而这句话很显然是宾语之间的比较，即rice所有的蛋白质和wheat所有的蛋白质在质量上的比较。
老鸟不难发现GMAC常常使用定语从句比较宾语。即Rice has protein that has higher quality than that in wheat.
同样要改写成主语比较的话Rice has protein of higher quality than wheat（does）.

ps，rice那道题当然也可以以In addtion to doing这里的逻辑主语为线索把答案定在B和D上，但是我在这里谈的还是主语比较以及宾语比较。

Ron: you've learned a lesson here: the gmat's preference for that 'do' is not absolute.

from a 100% strict semantic viewpoint, i agree with you here: there's technically an ambiguity. however, we now have evidence, in the form of this problem, that the gmat doesn't consider ALL of these 'ambiguities' as truly ambiguous. rather, provided that the 'second meaning' is sufficiently absurd AND nonparallel (note the obvious logical nonparallelism of compairing total fat to livestock), it's ok to eliminate the 'do'.

sigh.

remember, we don't make the rules; they do. but with each problem like this one that you study, you'll have a better idea of exactly what their rules are.
