想知道为什么A不对
suppliers are growing fish twice as fast as their natural growth rate
和
suppliers are growing fish twice as fast as they grow naturally
有什么区别，谢谢~

虽然笔记里面说A比较概念不对称，但我觉得还有一个关键就是fast不能修饰rate，英文里面不能说rate很 fast啊~~~

1.(24465-!-item-!-188;#058&000982)

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

C项可否理解为人工养殖鱼类的正常速度与两倍速度的对比？
D项中they指代的是suppliers还是fish?

我也想问一下 D中they指代的问题，为啥就指代的是suppliers而其他选项，例如A就是指代的fish，如果是就近指代的话，那D为啥又不可以呢

如果你的意思是：C的比较对象都是人工养殖，一个是正常速度，一个是两倍速度（即suppliers grow fish naturally没有逻辑意思上的问题）

如果是这样，请注意这里naturally的含义，不是“正常的”，而是“in a way that is the result of nature, not of someone's actions”（朗文）。既然无关someone’s actions，那么suppliers怎么能grow fish naturally呢？

2关于they的指代
一开始我也在纳闷这they到底是指代fish还是指代suppliers。但后来我发现，这不是考点，每个选项都有they/them/their，而当中哪个选项想要成为正确选项的话，必定这个指代要和未划线部分中的“raising them”中的them指代一致，即指代fish。

A选项 suppliers are growing fish twice as fast as their natural growth rate
这里的fast是做状语 是副词 不能修饰rate 退一步说 即便fast是形容词 它与rate也是不搭配的
故而A B排除

C选项 suppliers are growing fish twice as fast as growing them naturally, cutting their feed allotment by nearly half and raising them on special diets.
排除C的原因可能是产生了歧义 即可以理解成第二个growing...与cutting...and raising..平行
A is as fast as B, C and D. 而实际上A只与B有比较关系，C，D是伴随状语

接受，rate 不能用fast 形容。

请问一下，这个as ...as结构不是要求左右对称吗？第二个as后面的结构一定在之前出现过，可以这个正确答案中符合并列结构吗？

尝试解答：

To meet the rapidly rising marketdemand for fish and seafood, suppliers are growing fish twice as fast as theirnatural growth rate, cutting their feed allotment by nearly half andraising 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, cuttingtheir feed allotment

(D) they grow naturally, cuttingtheir feed allotment

(E) they grow naturally, with theirfeed allotment cut

做比较题目关键是看清楚比较对象，以及哪些部分是重复的，可以缺省。

在此题中，suppliers grow fish主谓宾齐全，因此可判断比较对象是状语，那么as之后的句子也应该是主谓宾齐全缺省状语，除非有重复成分，在这里DE符合条件，根据后面的and判断平行结构的对称性，选D。

as...as与than的道理是一样，本题也可以改成suppliers are growing fish faster than they grow naturally，这样看起来就更加明白了。
再例如：I run faster than you (run).和I run twice as fast as you (run). I run twice faster than you (run).
我刚开始也选了A，但是这道题再次提醒了比较对象之间的一致性和对称性这个红线是不能碰的，不论句式多复杂，都不能改变这个原则。

鱼鱼儿

D选项中they grow naturally中的they是指fish吧？grow是生长的意思，如果句子中出现多个they\them，位置接近又指代不同的意思，显得很混乱；
D中两个句子并列，比较对象是第一种情况下的fast程度和第二种情况下的fast程度，是对状语的比较。

不知道说的对不对，求大神讲解
