求证：Prep08所说的主系表结构后的逗号+VING不可以表示伴随结构

heidiym

在做prep08的一套题中，笔记的原话是“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.原题如下：

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.


答案是A,虽然通过Unlike后面比较了catching和legal size limits不对等；unlike后只能加名词也可以排除E，但是今天回头再看OG的时候，对于主系表+逗号VING不能表示伴随找到了一个反例，因此恳请各位NN帮我解释一下这个知识点？是我对Prep笔记的点误读了吗？我找到的反例如下：

Ryunosuke Akutagawa‘s knowledge of the literatures of Europe, China and that of Japan were instrumental in his development as a writer, informing his literary style as much as the content of his fiction.

a)that of Japan were instrumental in his development as a writer, informing his literary style as much as
b)that of Japan was instrumental in his development as a writer, and it informed his literary style as well as
c)Japan was instrumental in his development as a writer, informing both his literary style and
d)Japan was instrumental in his development as a writer, as it informed his literary style as much as
e)Japan were instrumental in his development as a writer, informing both his literary style in addition to

这道题答案是C，论坛上的解释都是说表示伴随。但是这句话明显是主系表结构：knowledge were instrumental。但是这里就是解释说明，VING伴随主句做状语，这我觉得与Prep上的观点有些矛盾。希望NN们伸手相助，我很困惑。。

S be O, doing 这个结构中，且不说doing是“表伴随”还是“表结果”这种多说无益的话题，但doing的主语当然可以是S。这个和 SVO, doing 中的doing并无差异（doing主语可以是S，可以是O，可以是没有明确主语），也不需要区别对待。

论坛上有很多的所谓语法总结都是针对某些特殊语境提炼出来的，提炼的人有时候清楚他想表达什么意思，看得人如果盲目推而广之就导致疑惑越来越多。
