问题补充：

Without you, I the first prize in the speech contest. Thank you, John.

A. can’t win

B. won’t win

C. hadn’t won

D. wouldn’t have won

答案：

A. can’t win

B. won’t win

C. hadn’t won

(答案→)D. wouldn’t have won

解析：考查含蓄虚拟语气。句意：要是没有你，我就不可能做演讲比赛中得一等奖。谢谢你，John。根据信息词without可知隐含着虚拟,而且与过去的事实相反，故选D。
