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

Answer: D

不明白为什么C不对，觉得前后时态应该一致啊？为啥前面用are growing，后面却用grow？

NN们，请帮忙解答一下吧！

自己顶！

仔细研究，觉得这道题可能的理解是：

人养的鱼生长速度是这些鱼在自然生长状态下的2倍。这样理解就顺了。

而且如果选C可能造成growing, cutting, raising三个动作平行的错觉，容易产生歧义。
