Question

7. Stop complaining about it.             ，we might not even have had the spot on the rooftop.(hesitate)

别再抱怨了。再犹豫得更久一些的话，我们恐怕连房顶上的这个位置都占不到了。

Answer 1

7. If we had hesitated longer / Had we hesitated longer 考查虚拟语气。当表示与过去的事实相反时， 主句用would / might / should + have done,而从句用had done。 根据"might not even have had" 可知，是对过去的虚拟，从句用过去完成时。本句可省略if,把had提到句首。
