If the dog hadn't woken us,we woudn't have noticed the fire and it _to the house nest door?A.could spread B.should have spread C.would spread D.might have spread
答案是D
这是一句表达虚拟语气的句子.if从句表达的是对过去的假设,所以整个句子应该是过去的事情,主句就要用情态动词+have+done的结构.这里主句表达的是一种可能性,所以用might表示可能性.

D.might have spread是虚拟语气的主句,对过去的情况加以推测;could spread 和would spread 不是虚拟语气的主句; should have spread 是“本应该蔓延却没有蔓延”,不是虚拟语气的主句,且语意也错误

D
虚拟语气
