虛擬語氣定稿

1、虛擬語氣使用虛擬語氣的句式紛繁復(fù)雜，概而言之，可從下面三種情況來掌握：1虛擬條件句(非真實條件句)。2、由should +動詞原形構(gòu)成虛擬語氣3、虛擬語氣的其它句型。一、虛擬條件句(非真實條件句)：條件狀語從句是非真實情況，在這種情況下要用虛擬語氣。1條件從句與現(xiàn)在事實不一致，其句型為：If主語+過去時，主語+ should (could, would,或might )+動詞原形，如：If I were you, I would study hard.If it rain ed, I would not be here now.2、條件從句與過去事實不一致，句型為：If主語+ had +過去分

2、詞，主語+ should (could, would,或might) + have+過去分詞，如：If the doctor had come last ni ght, the boy would have saved.If I had not studied hard, I would have failed in the exam last term.3、條件從句與將來事實不一致，句型為：If 主語+ should、斗_ + do,王語+ should (could )+ 原形 do were to過去時(If it should rain tomorrow, we would stay

3、at home.If I were to go to the moon one day, I could see it with my own eyes.If you missed the film to ni ght, you would feel sorry.常見考點：1 對將來虛擬時，If條件句中，應(yīng)用 should,不用“ would。If I should have tine next week, I would visit you.2、 混合虛擬”(錯綜虛擬)，如主句可能是現(xiàn)在的情況，條件句也許是發(fā)生在過去的情況。If I were you , I would not have a

4、ttended yesterday meeting.(主句對現(xiàn)在虛擬，從句對過去虛擬)If you had atte nded yesterday meeti ng, you could know what to do now.(主句對過去虛擬，從句對現(xiàn)在虛擬)3、結(jié)合倒裝考查在條件句中如果出現(xiàn)were, had, should等be動詞或助動詞，可省去if,從句中用倒裝語序。Had the doctor come last night, the boy would have saved.(If the doctor had come lastnight )Were I to go to th

5、e moon one day, I would see it with my own eyes. (If I were to go to )Should it rain tomorrow, we would stay at home. (If it should (woul d x ) rain tomorrow )4、同一句中，既有真實情況又有虛擬語氣I could have helped you with your work , but I was （had been x） too busy then.If it were not for the fact that she sing ,

6、I would invite her to the party.A couldn t B shouldn t C cantD might not二、由 should 動詞原形構(gòu)成虛擬語氣由should +動詞原形構(gòu)成虛擬語氣，主要適用于以下兩種情況A 在表示命令、建議、要求等名詞性從句中We suggested that the meeting should not be held.It was required that the crops should be harvested at once. （主語從句）Mother in sisted that John go to bed at 9

7、 o（賓語從句Clock.The suggestion that he be invited was rejected. （同位語從句）That is their demand that their wages be increased. （表語從句）B、It s（ high）time 句型主語+ should+ 原形It s time that you should go stchool.注意： 在該句型中 should 不可省略 該句型中的虛擬語氣，還可以由主語過去時構(gòu)成It s time that yowuent to school.三、通過推移時態(tài)構(gòu)成虛擬語氣該情況主要適用于以下句型1

8、、wish 后的賓語從句：與現(xiàn)在愿望不一致 主語過去時；I wish I were Bill Gates. 我要是比爾蓋茨就好了。與過去愿望不一致主語+ had+過去分詞；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,might）+原形。I wish I could meet you tomorrow at the party.He wishes he might do better next time.2、 as if （as though） 引導(dǎo)狀語從句和表語從句

9、時，其虛擬語氣的構(gòu)成，與wish 一樣She loves the children as if they were hers.The girl screamed （ 尖叫 ） as if she had seen a ghost.I felt as if we had known each other for years. 注意： as if 后面的從句，如果表示從句的情況是有可能會發(fā)生的，則用陳述語氣Look at the dark clouds! It seems as if it is going to rain.3、would rather 引導(dǎo)的從句 從句中用一般過去時，表示現(xiàn)在或?qū)?/p>

10、來的愿望時，Id rather you paid the money right now. （ 現(xiàn)在）I d rather you came next week. （將來） 從句中用過去完成時，表示一個過去的愿望。I d rather I had not shouted at you yesterday. （ 過去 ） 注意： would rather 后面可接動詞原形I would rather stay at home tomorrow.I would rather I stayed at home tomorrow.四、一些常用虛擬語氣的其它句式 If only 引起的感嘆句“ How

11、I wish+賓語從句”If only he could come! 他要能來就好了。If only I had known the answer yesterday! 我要早知答案就好了。解題思路：轉(zhuǎn)換成“ I wisIU賓語從句” without, but for, otherwise 引起的短語或句子常暗含著含蓄條件。WitIout you, I would never know Iim.But for your cooperation, we wouldnt Iave done tIe work so well. = If it were not for yourcooperation

12、, we we wouldn Iavedtone tIe work so well.解題思路： 轉(zhuǎn)換成 if 引導(dǎo)的非真實條件句But tIat sIe was afraid, sIe would Iave said no to you.=If sIe Iad not been afraid, sIe would Iave said no to you.I am busy now; otIerwise I would do you tIe favor!= If I were （was） not busy now, I would do you tIe favor!虛擬語氣練習(xí)1.
