Question

___________, he would have been fired.

A．Had he lied to the boss	B．Did he lie to the boss
C．If he has lied to the boss	D．If he lies to the boss

Answer 1

A

考查条件句中虚拟语气的形式。条件句中的虚拟语气根据不同的时间有三种不同的形式：

时间	从句谓语形式	主句谓语形式
将来	动词过去式(be用were) should + 动词原形 were to + 动词原形	would / should / might / could + 动词原形
现在	动词过去式(be 用 were)	would / should / might / could + 动词原形
过去	had +动词过去分词	would / should / might / could have + 动词过去分词

根据主句含义，他将会被解雇。可知从句假设的是在过去已经完成的动作，故用从句用过去完成时态。故选A，其他选项时态不符。
