GWD-8-Q11 对there be 句型主语对比的疑惑

There are no legal limits, as there are for cod and haddock, on the size of monkfish that can be caught, a circumstance that contributes to their depletion through overfishing.

A There are no legal limits, as there are for cod and haddock, on the size of monkfish that can be caught, a circumstance that contributes to their depletion through overfishing.

B There are no legal limits on the size of monkfish that can be caught, unlike cod or haddock, a circumstance that contributes to depleting them because they are being overfished.

C There are legal limits on the size of cod and haddock that can be caught, but not for monkfish, which contributes to its depletion through overfishing.

D Unlike cod and haddock, there are no legal size limits on catching monkfish, which contributes to its depletion by being overfished.

E Unlike catching cod and haddock, there are no legal size limits on catching monkfish, contributing to their depletion because they are overfished.

正确答案为A

我的疑问是
unlike是parallelism的signal word，那在BDE里面，根据句子结构分析，对比的究竟是哪个和哪个？

首先我在GMAT 2008prep语法笔记里面看到：

A. Correct；monkfish单复数同型(见补充说明)，their指代monkfish；there be句型的平行要补出there be。

B. unlike的两个对象不可比(size v.s. monkfish)，且放在中间，易产生修饰歧义；depleting them是主动语态，可是动作发出者又不明，错误；用because引导的原因状语从句来表示方式太过于累赘。

C. which不能指代一句话；应该用their来指代monkfish，因为monkfish前面没有冠词，所以是复数。

D. unlike比较双方不可比；its指代复数名词monkfish错误；by不如through好；being overfished修饰了contributes与contributes的逻辑主语which，不合理。

E. Unlike比较双方不可比；前面there be句型是主系表结构，所以后面contributing不能表示伴随结构，而是作为形容词修饰前面的名词catching monkfish；用because引导的原因状语从句来表示方式太过于累赘。

这里B选项的解析说的是对比的是size of monkfish 和cod and haddock（括号里写的是size vs. monkfish,但是我感觉它说的是拿size和鱼比较。）

然后我在beatthegmat论坛上看到：

来源：https://www.beatthegmat.com/gprep-there-are-no-legal-limits-as-there-are-for-cod-and-t296950.html

B: There are no legal limits, unlike cod

D: Unlike cod, there are no legal size limits

In these options, cod is illogically compared to legal limits.

Eliminate B and D.

BD将cod和legal limits比

C: monkfish, which contributes....through overfishing

Here, overfishing seems to refer to monkish, implying that MONKFISH is OVERFISHING -- a nonsensical meaning.

E: Unlike catching, there are no legal limits

Here, catching is illogically compared to legal limits.

Eliminate E.

E将catching cod和legal limits比较

所以是哪个对啊？

另外对于there be句型有一个疑惑，there be主语是there，但是逻辑主语是there be后面跟着的名词对吗？所以如果比较主语的话，是将there be后面跟着的名词拿出来吗？

菜鸟学习中，多多指教

There are no legal limits, as there are （legal limits）for cod and haddock, on the size of monkfish that can be caught, a circumstance that contributes to their depletion through overfishing.

主语是 no legal limits , legal limits

B There are no legal limits on the size of monkfish that can be caught, unlike cod or haddock, a circumstance that contributes to depleting them because they are being overfished.

size of monkfish 不能和cod or haddock比
要么size 和 size 比，要么monkfish （鱼）和 cod or haddock （鱼）比

B: There are no legal limits, unlike cod
D: Unlike cod, there are no legal size limits
In these options, cod is illogically compared to legal limits.
Eliminate B and D.

上面就是典型例子啊，unlike x ,y  中的x和y要符合逻辑
                           unlike tom , jack is ...
                           unlike tom's success , jack's success ...
                           unlike the United States , China ...

上面的B和D选项都是拿cod(鱼)和no legal size limits （无合法尺寸限制）做比较，简化下就是拿cod和limits 做比较
