C: To meet the rising marketing demand for fish and seafood, suppliers are growing fish twice as fast as growing them naturally, cutting their feed allotment by nearly half and raising them on special diets.
我了解C与D的句意不同解释,有一个关于C的问题:
前面是suppliers are growing fish twice
后面是suppliers are growing fish naturally
如果这一句改写成suppliers are growing fish twice as fast as naturally,是否通呢?
