代词的问题。怎么也整不明白了

To meet the rapidly rising market demand for fish and seafood, suppliers are growing fish twice as fast as their natural growth rate, cutting their feed allotment by nearly half and raising them on special diets

A) their natural growth rate, cutting their feed allotment
B) their natural growth rate, their feed allotment cut
C) growing them naturally, cutting their feed allotment
D) they grow naturally, cutting their feed allotment
E) they grow naturally, with their feed allotment cut

这道题挺老了吧。但总是搞不懂。为什么D就是no human intervention，C中就没有这个意思呢？

请大牛解释~

到底是谁代指谁。they their ,头晕了。

用逻辑意思来解答

C  suppliers are growing fish twice as fast as （suppliers are )growing them naturally

这如何能行得通呢

比较的对象是 人工养殖的鱼和自己自然生长的鱼生张速度的比较

lz搜索一下prep语法笔记，第一道题啊。解释得很好，印象很深

请问这里是怎么看出来they grow naturally里面的they不是指代渔民而是鱼的呢？

biantaishabi

因为这个grow后面没有宾语

t8chang

但是从纯语法角度讲，这个they可以指鱼么？如果可以的话D就是指代不清的错误啊？

biantaishabi

可能是they前面最近的一个词是鱼而不是渔民把

这样想吧，第一个as后面接的是fast，fast是副词修饰的应该是前面suppliers are growing fish 中的growing吧，那么，相对应的，第二个as后面的词应该也是一个动词才对，所以在CD中间选；从逻辑意思上来看，应该是渔民按照鱼类自然生长速度的两倍饲养它们，那么，自然生长速度就应该没有人为因素，如果选C的话应该是和前面的suppliers are growing fish 中的growing fish并列，主语变成了suppliers，那么就有人为因素了，D选项里面的they指代fish，主语就是fish，就是fish自己的自然生长速度了

还有哦，代词指代一般不会越过谓语动词指代的~~
