高考語法-虛擬語氣講解及練習(xí)

1、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(shí)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(shí)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 save

2、d. （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(shí)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

3、 to night, you would feel sorry.（混合虛擬）P.S:1、If條件句中絕對(duì)不可出現(xiàn)“would”。2、根據(jù)句中的時(shí)間狀語，有時(shí)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

4、 eyes.Should it rain tomorrow, we would stay at home.1.5 without, but, but for, 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(dòng)詞作同上的變化。 與現(xiàn)在事實(shí)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 no

5、w, otherwise I would do you the favor! 與過去事實(shí)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(shí)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,prop

6、osal ,desire, plan, idea時(shí):>主語（should）do，如：Mother insisted（堅(jiān)決要求） that John go to bed at 9 oclock.（賓語從句）（P.S當(dāng)insist意為“堅(jiān)稱說”，不要虛擬語氣?。￤e 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！）It was required that the crops sho

7、uld 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/ suggusted/ proposed/ requested/ ordered +that+主語+（should）+doIt is + a pity/ a shame/ no wonder/ an honor +that+主語+（should）+do如：It

8、is stange that he (should) go himself.P.S. 上述詞只表事實(shí)，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 sch

9、ool. =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

10、= 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，表示不肯能實(shí)現(xiàn)的愿望，所以用虛擬語氣；hope+從句，表示可能實(shí)現(xiàn)的愿望，不用虛擬語氣2.6 would rather/ as if（though） 與現(xiàn)在/ 未來事實(shí)相反：did 如： I would rather you stayed here now.
