题目内容
11.They were abroad during the months when we were carrying out the investigation,or they _____ to our help.( )A. | would have come | B. | could come | C. | have come | D. | had come |
分析 在我们进行调查的那几个月他们正在国外,不然的话他们就来帮忙了.
解答 答案:A.根据题干中的or可知其引导的是含蓄虚拟条件句,相当于if引导的虚拟条件句.根据句中they were abroad的were可知事情发生在过去,所以or引导的含蓄条件句是对过去情况的假设,所以谓语动词形式应为would/could/might/should have done.故选A.
点评 此题考查含蓄虚拟条件句.解题时根据题干中的介词(短语)提示,如with,without,or,otherwise,but for等,再结合上下文的语境找到隐藏的条件,从而确定是对什么时间的虚拟假设.
