虚拟语气谓语动词的几种表现形式

    1.用在虚拟条件句中

    虚拟条件句及其主句的谓语形式可归纳如下

 

                 从句谓语              主句谓语

与现在事实相反  were, did   would (should, could, might) +v

 

与将来事实相反  should do,  would (should, could, might) +v

(可能性极小)  were+to+v  

 

与过去事实相反  had done    would (should, could, might) + have done

 

    1I would certainly go if I had the time.

    2How nice it would be if you could stay a bit longer.

    3She would have come if we had invited her.

    如果条件从句中包含有were, had, shouldcould,有时可把if省略掉,但这时要把were, had, shouldcould放在主语前面(这种结构在口语中较少使用)。例如:

    1Had we made (= If we had made ) adequate preparations, we might have succeeded.

    2Were there no gravity, there would be no air around us.

 

    3Should it rain tomorrow, the meeting would be put off.


生词表:
  • adequate [´ædikwit] 移动到这儿单词发声  a.足够的;适当的   (初中英语单词)
  • gravity [´græviti] 移动到这儿单词发声  n.严肃;严重;重力   (高中英语单词)
