问题补充：

Thank you very much. Without your help we car started.

A. didn’t get

B. hadn’t got

C. couldn’t get

D. couldn’t have got

答案：

A. didn’t get

B. hadn’t got

C. couldn’t get

(答案→)D. couldn’t have got

解析：考查虚拟语气：Without your help是隐含的虚拟语气，相当于：If it hadn’t been for your help，是和过去相反的虚拟条件句，主句用情态动词could+have done，句意：谢谢，没有你的帮助我们就不能让汽车启动。选D。
