Question

We would have called a taxi yesterday if Harold ________ us a ride home.

A．didn’t offer

B．wouldn’t offer

C．hasn’t offered

D．hadn’t offered

Answer 1

D

试题分析：句意：如果哈罗德昨天没有送我们回家的话，我们将叫一个出租车。从主句的谓语动词would have called可以看出这是对过去的虚拟，那么从句应该用had+done，故选D。
点评：本题难度适中。虚拟语气是近几年高考的热点，虚拟语气的情况复杂，形式多样，需要考生牢记它们的不同的用法，再根据不同的语境分析句子应该用哪种情况的虚拟。
