题目内容
19．If Harold hadn't given us a ride yesterday，we ________ home at midnight．（ ）| A． | arrived | B． | would arrive | ||
| C． | had arrived | D． | would have arrived |
分析 如果Harold没有给我们搭便车，我们会半夜到家．
解答 答案是D．本题考虚拟条件句．与过去事实相反的虚拟条件句中往往用过去完成时，而题干if 从句中的时态是hadn'g given，可见这是与过去事实相反的虚拟条件；与过去事实相反的虚拟条件句的主句中用"would/should/could/might+have done"，由此判断答案是D．
点评 在掌握虚拟语气的规则的基础上，判断题干属于什么类型的虚拟，然后根据语境，选用恰当的动词形式表达虚拟．
