题目内容
3.We were delayed at the airport.Otherwise,we here by lunch.( )A. | must have been | B. | could be | C. | should be | D. | would have been |
分析 我们在机场被耽搁了.不然的话,我们在午饭前就到这里了.
解答 答案:D
根据题干中的otherwise可知,此句是含蓄虚拟条件句,相当于if引导的虚拟条件从句.由谓语动词were delayed可知是过去的一件事,所以主句的谓语动词形式应为would/could/might/should have done.原句可改为If we hadn't been delayed at the airport,we would have been here by lunch.故选D.
点评 含蓄虚拟条件句常将条件从句隐藏在上下文一定的单词短语中,常见的提示词有:with、without、otherwise、or、but for、but等.解题时,一要抓住这些关键词的提示;二要确定是对哪一个时间(过去、现在或将来)的假设.如对现在和将来时间假设,主句的谓语动词形式为would/could/might/should do;如对过去时间假设,谓语动词则为would/could/might/should have done.
