选择题
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
答案
A
题目分析：句意：如果没有你的慷慨帮助，我不可能度过那段痛苦的时期。without your generous help="If" I had not had your generous help表示虚拟语气，如果过去我没有你的慷慨帮助，所以主句应用could /should/would/might+ have+done.故选A。
