高考英語語法專題講解-虛擬語氣1 虛擬條件句：1.1 與現(xiàn)在事實不一致，其句型為：If +主語did，主語should（could, would, 或might）do.如：If I were you, I would study hard. （可倒裝）If it rained, I would not be here now.1.2 與過去事實不一致，句型為： If +主語haddone，主語should（could, would, 或might）havedone.如：If the doctor had come last night, the boy would have been saved. （可倒裝）比較這一句：If the doctor had come last night, the boy would be saved. -（混合虛擬:要求根據(jù)語境判斷！）1.3 將來事實不一致，句型為：do，主語should（could ，would, 或might）do. 如：If it should rain tomorrow, we would stay at home.（可倒裝）If I were to go to the moon one day, I could see it with my own eyes.（可倒裝）If you missed the film tonight, you would feel sorry.（混合虛擬）P.S:1、If條件句中絕對不可出現(xiàn)“would”。2、根據(jù)句中的時間狀語，有時可能出現(xiàn)“混合虛擬”的情況，即主句可能是現(xiàn)在的情況，條件句也許是發(fā)生在過去的情況，但都是遵守上述句型。1.4 虛擬倒裝：在條件句中如果出現(xiàn)were, had, should可省去if，將主語與這些詞倒裝，例如：Had the doctor come last night, the boy would have saved.Were I to go to the moon one day, I would see it with my own eyes.Should it rain tomorrow, we would stay at home.1.5 without, but, but for（要不是）, otherwise引起的短語或句子常暗含虛擬（語氣較為含蓄）,分3種情況動詞作同上的變化。1.5.1 與現(xiàn)在事實相反：Without you, I would never know him. But for your cooperation, we wouldnt have done the work so well. I would be most glad to help you, but I am busy now.I am busy now, otherwise I would do you the favor! 1.5.2 與過去事實相反：But that she was afraid, she would have said no. I would have come to the party yesterday, but I was working.2 名詞性虛擬語氣：在表示命令、建議要求、驚嘆、感嘆、愿望時的名詞性從句中需用虛擬語氣，具體類型有：2.1 遇到：suggest, suggestion, insist, insistence, order, demand, request, command, propose, proposal ,desire, plan, idea時:主語（should）do，如：Mother insisted（堅決要求） that John go to bed at 9 oclock.（賓語從句）（P.S當(dāng)insist意為“堅稱說”，不要虛擬語氣！）We suggested that the meeting should not be held.The suggestion that he be invited was rejected.（同位語從句） （P.S當(dāng)suggest意為“暗示，表明”，不要虛擬語氣?。㊣t was required that the crops should be harvested at once.（主語從句）That is their demand that their wages be increased.（表語從句）2.2It is + natural/ necessary/ important/ surprising/ strange/ funny/extraordinary/ suggested/ proposed/ requested/ ordered +that+主語+（should）+doIt is + a pity/ a shame/ no wonder/ an honor +that+主語+（should）+do如：It is strange that he (should) go himself.P.S. 上述詞只表事實，不表情感 Should + do (表現(xiàn)在或?qū)? 2.3 主語+ be+ sorry/ surprised/ disappointed (表情感的詞) +that +主語+ Should+ have+ done (表過去)(這里的should意為“竟然”)如：Im sorry that things should have come to this.2.4 Its (high) time that+主語shoulddo / 主語did，例如：Its time that you went to school. =Its time that you should go to school. 你該去上學(xué)了。（早該去了，可你沒去）2.5 wish后的賓語從句：與現(xiàn)在愿望不一致: 主語did；I wish I were you.與過去愿望不一致: 主語haddone；I wish I had visited the white House when I was in the states.與未來愿望不一致: 主語would（could）do。I wish I could met you tomorrow at the party. wish的感嘆句: How I wish+根據(jù)3種情況的相應(yīng)句法 = If only （用法同wish） 如： How I wish I had known the answer. = If only I had known the answer. P.S. wish+從句，表示不可能實現(xiàn)的愿望，所以用虛擬語氣；hope+從句，表示可能實現(xiàn)的愿望，不用虛擬語氣2.6 would rather/ as if（though） 2.6.1 與現(xiàn)在/ 未來事實相反：did 如： I would rather you stayed here now.
