.I would have come earlier,but I ________ that you were waiting for me.
A.didn’t know B.hadn’t know
C.would have known D.haven’t known
这一题为什么选a啊 虚拟语气对过去的假设是if had done +would / should / could / might have done 所以空中为什么不是had done
.I would have come earlier,but I ________ that you were wait
本题考察虚拟语气和真实语气的结合,同时前一句省略了if从句.如果不省略应该是:If I had known earlier,I would have come earlier,but I ________ that you were waiting for me.如果我早点知道的话,我会早点来的(事实上我并不知道,也没有来早),但是我并不知道你在等我.
but前面是虚拟的,后面是真实的,所以要用一般过去时.
你说的句型是对的,但是首先要分清那句是主句,哪句是从句,并且哪句是虚拟哪句是真实.这一题如果你选B,应该是把前一句当成从句,后一句当成主句了.这个句子整体结构是but连接的两个并列句,后面其实是一个独立的句子.
