GWD29-24没人问过

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

答案是B，我认为B有歧意，主动宾比较中应该补出助动词来消除歧意。而且后面这个more of a kind of fat让我看着不舒服。

我选C，虽然他看上去不美，不过也比B强。Less和More都是形容词，比B中一个名词一个形容词对称多了。

感觉B和C都不怎么样。。。

b有把 fat与livestock进行比较的嫌疑

c的that of加得很古怪。。。变成animals与fat进行比较了。如果have可以省略的话，B可能更好一些吧。。。

晕死,写了半页由于错误没有了.

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

由于and并列,所以保证了and后面的省略不会有歧义

前面的比较livestock后面有(fed on grain)修饰,不加助动词不会有歧义

且加了助动词不好因为:

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

那个do不知道是做强调的那个do还是补出的谓语

(马后炮式的解释)

Here is my opinion,pls kindly advice.

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.

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

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
            

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

(A)   wild animals have less total fat 比上do livestock (合理)à
        do我会认为是因为不要和fed连才故意倒装，这样说的通嘛?

(B)   wild animals比上livestock(合理)

(C)   wild animals have less total fat或wild animals比上that of livestock(不合理且会有歧意)

(D)   total fat of wild animals比上livestock(不合理且会有歧意)

(E)    total fat比上that of livestock(合理)

(A)(B)(E)中选(B)的原因是(A)(E)中的they没有明确指代

那个很经典的写比较句型省略的文章上举的例子是

Rice has protein of higher quality than whetat does.

可能这里是没有理由倒装吧.

就算倒装,理解的时候还是要还原的阿.

(个人想法,因为实在是找不到理由省略那个DO了)

同意

补动词在意思上会更好，但是这个句子补上去后反而更怪，不补的话因为只有主词不同，句子也单纯，所以也不会影响到读者对句子的了解，因此不补也是ok的

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.

比较结构有三个结构都是对的：

第一个结构：是正规的平等对称，所有主谓宾齐活儿，没有歧义，是最清楚的一种。

第二个结构：是倒装结构，即本题中的A

第三个结构：是省略结构，即动词或助动词的省略，即本题中的B

二，三比较复杂，也不容易看，具体哪个更好得看每个不同的题，以及比较结构的其它成份（比如定语从句或是就近修饰等都会影响句子结构）比如本题中用省略结构就比较好，如果补出倒装的话，反而不对称了。也许碰的其它的题，可能倒装更对称一些，具体情况具体再看吧。

恩，偶已经看到好几句 比较结构 把do省略了。

ETS才是王道
