Question

I ______ through that bitter period without your generous help.

A．couldn’t have gone	B．didn’t go
C．wouldn’t go	D．hadn’t gone

Answer 1

A

解析试题分析：句意：如果没有你慷慨的帮助我不可能安然度过那段痛苦的时期。由句意可知考察对过去的虚拟语气，把without your generous help看做是个虚拟语气的条件句，主句对过去虚拟用could/would/might/should + have +done，故选A。
考点：考察虚拟语气。
点评：对于虚拟语气的练习，第一要熟练掌握它的基本句型，第二要注意从句意或一些固定用法上判断出是虚拟语气，如without，but for,otherwise等词了。还要注意虚拟语气的多样练习。
即学即练：I would have come earlier，but I ___that you were waiting for me.
