六级之虚拟语气可用.pdf

浅谈虚拟语气的十大句虚拟语气分三种情况来掌握： 1 、虚拟条件句； 2、名词性虚拟语气； 3、虚拟语气的其他用语一、虚拟条件句：条件状语从句是非真实情况，在这种情况下要用虚拟语气 1 、条件从句与现在事实不一致，其句型为：句型 1： If 主语过去时， 主语 should（could, would, 或 might ）动词原形 , 如： (1) If I were you, I would study hard. (2) If it rained , I would not be here now. 2 、条件从句与过去事实不一致，其句型为：句型 2： If 主语 had过去分词，主语should （could, would, 或 might ） have 过去分词，如： (3) If the doctor had come last night, the boy would have saved. (4) If I had not studied hard, I would have failed in the exam last term. 3 、条件从句与将来事实不一致，其句型为：句型 3：If 主语过去时 /should 动词原形 /were to 动词原形 ,主语 should （could, would, 或 might ）动词原形，如： (5) If it should rain tomorrow, we would stay at home. (6) If I were to go to the moon one day, I could see it with my own eyes. (7) If you missed the film tonight, you would feel sorry.注意问题： 1 、If条件句中绝对不可以出现“would”。

2 、根据句中的时间状语，有时可能出现“混合虚拟” 的情况，即主句可能是现在的情况，条件句也许是发生在过去的情况，但都要遵守上述句型, 如:(8)If you had studiedhard before, you would be a college student now and you would graduate from a college in four years time. 3 、在条件句中如果出现were, had, should 可省去 if ，将主语与这些词倒装，例如：(9) Had the doctor come last night, the boy would have saved . (10) WereI to go to the moon one day, I would see it with my own eyes. (11) Should it rain tomorrow, we would stay at home.二、名词性虚拟语气：在表示命令、建议、要求、惊叹时的名词性从句中需用虚拟语气，基本句型：句型 4： 主语（ should ）动词原形，如：(12) Mother insisted that John (should )go to bed at 9 oclock.（宾语从句）(13) It was required that the crops (should) be harvestedat once.（主语从句）(14)It is surprising that she shouldn t pass the maths exam. （主语从句）(15) The suggestion that he (should) be invited was rejected.（同位语从句）(16) Their demand is that their wages (should )be increased.（表语从句）注意： 在这种句子中绝不可以出现“would”“must”“ could ”等。

三、虚拟语气在一些特殊词中的使用或含蓄条件句：句型 5：wish 后的宾语从句：与现在愿望不一致：主语过去时；与过去愿望不一致：主语 had过去分词 /could have过去分词；与未来愿望不一致：主语 would（could ）动词原形如；(17) I wish I were you. (18) I wish I had visitedthe white House when I was in the states. (19) I wish I could meet you tomorrow at the party.句型 6：It s time句型：当 It s time后用 that 从句时应该为：主语 should 动词原形或 主语过去时，例如：(20) Its time that you went /should go to school. 句型 7：If only引起的感叹句相当于“How I wish 宾语从句”，如：(21) If only he could come ! 他要能来就好了22) If only I had known the answer! 我要早知答案就好了。

句型 8：would rather, as if（though ）引导的句子也需使用虚拟，表示过去的情况用过去完成时，表示现在与将来的情况用过去时，如：(23) Id rather you posted the letter right away. (24) Id rather you had returned the book yesterday. (25) She loves the children as if they were hers. (26) Alan talked about Rome as if he had been there.句型 9：without, but, but for, but that, otherwise引起的短语或句子常暗含着含蓄条件如：(27) Without you, I would never know him. (28) But for your cooperation, we wouldnt have done the work so well. (29) But that she was afraid, she would have said no. (30) I would be most glad to help you, but I am busy now. (31) I should have come to the party yesterday, but I was busy. (32) I am busy now, otherwise I would do you the favor!句型 10： If it were not for./If it hadnt been for.(要不是因为 .) , 其后面的主句也需使用虚拟。

如：(33) If it were not for his help, I wouldnt gohome now. (34) If it hadnt been for the determined captain, all the passengers on the board wouldnt have been saved.。
