一道英语虚拟
1.Martin Luther Kin,Jr.was famous all over the world,even though he _____ his Dream Speech.
A.wouldn't make B.didn't make C.had made D.hadn't made
答案是B还是D?
2.Charles Darney insisted that he _____everything he could to make sure of Lucie's happiness.
A.do B.does C.did D.must do
为什么不是C,作"坚称"的意思
1.B,虚拟语气在as if/as though、even if/even though等引导的表语从句或状语从句中,如果从句表示的动作发生在过去,用过去完成时;指现在状况,则用一般过去时;指将来状况则用过去将来时.如:
He did it as if he were an expert.
Even if she were here,she could not solve the problem.
据以上分析,even if 后接过去式,主句用过去完成时,这种让步状语从句的虚拟与一般虚拟语气句式确实有差别,应该注意.
2.A,这里根据句意,应该理解为坚持要求的意思,也就是后面要用should+动词原形.做坚称解应该用过去完成时.
