If only the committee __ the regulations and put them into effect as possible.

题目

If only the committee __ the regulations and put them into effect as possible.
A.approve 　　B.will approve C.can approve 　　D.would approve
为什么是D呢,if哦nly不是引导从句吗,那么对照虚拟语气表,那么ABCD都不对啊.would+V不是主句才用吗?

答案

if only不是引导状语从句的,而表示一句完整的虚拟句子.意思是：要是.就好了.例如：
If only I were you.要是我是你就好了.
If only I would go there.要是我会去那里就好了.
明白了吗,朋友?
