prep1-148 改变原意了吗

148.      (32773-!-item-!-188;#058&006296)

In contrast to some fish eggs requiring months to incubate, the Rio Grande silvery minnow produces eggs that hatch in about 24 hours, yielding larvae that can swim in just three to four days.

(A) some fish eggs requiring months to incubate

(B) some fish, whose eggs require months to incubate

(C) some fish that have eggs requiring months to incubate

(D) the requirement of months of incubation for some fish eggs

(E) requiring months of incubation, as some fish eggs do

prep的解释说E as some fish eggs do改变原意，怎么看出来是改变原意了？

as some fish eggs do里的do不能向前指代，因为没有谓语动词，只能向后指代produce，变成some fish eggs(暂时不考虑不对称问题)和minnow是相似的，一样地in contrast to "requiring months of incubation"

所以句意也改变了

变成some fish eggs(暂时不考虑不对称问题)和minnow是相似的，一样地in contrast to "requiring months of incubation"

这里没太明白aeoluseros， 是不是说some fish eggs像minnow一样produce,怎么能跟requiring months of incubation联系起来呢？

你再给我说说吧，多谢拉

as some fish eggs do里的do不能向前指代，因为没有谓语动词，只能向后指代produce,所以as some fish eggs do是与minnow produce并列的，也即用“as + 句子”来表达了它们两个动作的相似性：some fish eggs像minnow一样produce,与requiring months of incubation这个情况相反（in contrast to）。

而原文要表达的意思是说，minnow和some fish eggs相反（in contrast to），some fish eggs是requiring months of incubation的，而minnow不用那么久，没几天就搞定的。

弱弱地问一句 为什么C选项不对呢

解释为“与那些要求卵需要一个月时间孵化的鱼相比···” 好像说得通啊~~
