        虛擬語氣謂語動詞的幾種表現形式

            1.用在虛擬條件句中

            虛擬條件句及其主句的謂語形式可歸納如下

         

                         從句謂語              主句謂語

        與現在事實相反  were, did   would (should, could, might) +v

         

        與將來事實相反  should do,  would (should, could, might) +v

        (可能性極小)  were+to+v  

         

        與過去事實相反  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.

            如果條件從句中包含有were, had, shouldcould,有時可把if省略掉,但這時要把were, had, shouldcould放在主語前面(這種結構在口語中較少使用)。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.


        生詞表:
      2. adequate [´?dikwit] 移動到這兒單詞發聲  a.足夠的;適當的   (初中英語單詞)
      3. gravity [´gr?viti] 移動到這兒單詞發聲  n.嚴肅;嚴重;重力   (高中英語單詞)
