江西普通高校专升本英语


               例如: If she were you (=Were she you) , she would go with Tom.

                   假如她是你,她就会和汤姆一起去。
               (2)与过去事实相反:
               例如: If I had had time at that time (=Had I had time at that time), I would have gone with you.

                   假如我那时候有时间,我当时就会和你一起去
               (3)与将来事实相反:
               例如:  If I were to visit /should visit the Great Wall tomorrow (=Were I to /Should I visit the Great Wall
                     tomorrow), I would take my family with me.

                   假如我明天去参观长城,我将会把我的家人也带上。
               注意:在否定句中not不可提至主语前。
               例如: (误)Were n’t I here now, I would be in the bus.
                   (正)Were I not here now, I would be in the bus.



               【真题演练1】  ___________so busy, I should go to the hairdresser’s.(2003年专升本)
               A. If I’m not          B. Had I not been      C. Was I not          D. Were I not
               【答案】D

               【解析】句意:如果我现在不忙,我会去理发店的。本题考查的是与现在事实相反的if虚拟条件
               句的省略倒装。根据句意,表示和现在的事实相反,因此推出从句的原句应该为If I were not so
               busy。省略倒装时,把were提前。故选D。



               【模拟演练1】  _______ you ________next Wednesday, I would introduce you to Tom.
                A. Were, to come      B. If, had come        C. Had, come          D. Did, come
               【答案】A
               【解析】句意:如果你下周来,我就会介绍Tom给你认识。本题考查的是与将来事实相反的if
               虚拟条件句的省略倒装。根据主句的谓语would introduce,推出原句的从句应该为If you were to

               come next Wednesday。省略倒装时,把were提前。故选A。


               3.错综时间虚拟条件句

               定义:当条件从句的动作和主句的动作不是同时发生,主句和从句的谓语动词的形式应分别根据
               各自所表示的时间加以调整的虚拟条件句。
               例如: If he had taken my advice, he would be better now.
                   假如他当时采纳了我的意见,他现在就会更好。
                 在本句中,从句表达与过去事实相反,而主句表达与现在事实相反

               注意:当从句与主句或上下文所表述的时间不一致时,我们切不可照搬某一种形式,而应该按照
               主从句中所表述的时间关系,去选择相应的虚拟形式。
