Weweredelayedattheairport.Otherwise,weherebylunch.()A.musthavebeenB.couldbeC.shouldbeD.wouldhavebeen
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
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.
