问题补充：

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：

(答案→)A. couldn’t have gone

B. didn’t go

C. wouldn’t go

D. hadn’t gone

解析：考查虚拟语气。without your generous help是含蓄的虚拟语气，等同于If it hadn’t been for your generous help, 与过去时相反，所以主句用could have done.
