The boy would have died, _______ on him

问题选择题

The boy would have died, _______ on him without delay.

A．if the doctor didn’t operate

B．if the doctor wouldn’t operate

C．would the doctor not operate

D．had the doctor not operated

答案

答案：D

考查虚拟语气条件句的倒装。句意：要不是这个医生立即给他动了手术，这个男孩本来会死的。“would+have+done”表示对过去事情的假设，意思是“本来会做”。结合语境可知条件句中描述的是已经完成的动作，选项ABC时态有误。虚拟语气条件从句不一定都要出现if，因为有些时候可以把助动词提前来达到省略if的作用，故选D。
