选择题
You didn’t let me drive. If we _______ in turn, you _______ so tired.
A．drove; didn’t get
B．drove; wouldn’t get
C．were driving; wouldn’t get
D．had driven; wouldn’t have got
答案
答案：D
考察虚拟语气，根据didn't let me drive可知，该句是对过去的虚拟，对过去虚拟从句要用过去完成时的形式，主句要用wouldn't have done 结构
句意为，你当时不让我开车，如果你当时让我和你轮流开的话，你就不会感到累了。
