1、精选学习资料 - - - - - - - - - 高中英语语法之虚拟语气讲解 The Subjunctive Mood 【The Subjunctive Mood】语气 mood是一种动词形式,用以表示说话者的意图或态度；英语中的语气有三种：陈述语气、祈 使语气和虚拟语气；直陈语气 indicative mood, 表示所说的话是事实；祈使语气 imperative mood, 表示所说的话是恳求或命令；虚拟语气 subjunctive mood, 表示说的话不是事实,或者是不行能发生的情形,而是一种愿望、建议或 与事实相反的假设等；一. 虚拟语气在条件句中的应用 学习虚拟语气在条件句中的用法

2、之前我们必需清晰条件句的种类：条件句有真实条件句与非真实条件 句或称虚拟条件句 两种；真实条件句所表的假设是可能发生或实现的,句中的条件从句与结果主句都用 陈述语气；如：If it doesnt rain tomorrow, I will go for a picnic. 假如明天不下雨,我就去野餐；Oil floats if you pour it on water. 你如把油倒在水里,油就浮起来；虚拟条件句所表的假设就是不行能或不大可能发生或实现的,句中的条件从句与结果主句皆须用虚拟语气；条件从句 主句与现在事实相违反 过去式（动词是 be 用 were ）should / would/c

3、ould/might + 动词原形与过去事实相违反 had + 过去分词 should / would/could/might + have +过去分词1 should + 动词原形should / would/could/might + 动词原与将来事实相违反 2 were + 动词不定式 形3 过去式 （动词是 Be 也可以用 were ）1. 与现在事实相反的虚拟条件句,条件从句的谓语用动词的过去式 be 的过去式用 were, 主句的谓语用 should （would, might , could） +动词原形；如：If it were not raining, we should g

4、o for a picnic.假如现在不下雨的话,我们就出去野餐了；（事实是：天在下雨,我们不能出去野餐；表示愿望；）If he came here, he might be able to help you. 假如他来这,他就能够帮忙你了；（事实是：他没来这,他不行能帮忙你；表示对他的良好印象；）2. 与过去事实相反的虚拟条件句,条件从句的谓语用had+过去分词,主句的谓语用should （ would, might , could）+ have 过去分词；如：She would have gone to the party if she had been invited. 要是起初她被邀请

5、的话,她就会去参与这次聚会了；（事实是：当时没有人邀请她,因此,她没有来参与聚会；表示懊悔；）If she hadnt called me, I would have overslept this morning.今日早上,她要是不叫我的话,我就会睡过头了；（事实是：她今日早上叫我了,我没有睡过头；表示感谢；）3. 与将来事实可能相反的虚拟条件句,条件从句的谓语用动词的过去式be 的过去式用were； should动词原形； were to动词原形,主句用should （would, might , could）+动词原形；如：If I were to be twenty years old

6、next year, I would take the course of French.明年我要是二十岁,我就会学法语；1 名师归纳总结 - - - - - - -第 1 页,共 15 页精选学习资料 - - - - - - - - - 高中英语语法之虚拟语气讲解 The Subjunctive Mood （事实是：我现在已经老了,明年我学不了法语了；）If it should fail, I would try again.要是失败了,我会再试一次；（事实是：有可能失败,可我会再试；表示未知；）虚拟过去式有时并不表示“ 不大可能实现的假设” ,而是表示一种期望或不期望发生的动作；如：If

8、ould pass the test if he had taken my advice 假如他听了我的劝说,他现在会通过考试；If I had spoken to him yesterday, I should know what to do now. 假如昨天我对他说了,现在我就知道该怎么办了；You would be much better now if you had taken my advice. 假如你接受了我的看法,你现在就会好得多；如条件从句用 if I were. ,主句就可用表任何时间的虚拟形式；如：If I were not busy, I would have com

9、e. 假如我不忙,我就会去了；were 表过去 If I were you, I would go. 假如我是你,我会去的；were 表现在 二. 连词 if 的省略假如虚拟条件句的谓语部分有were,had 和 should 时,可省略if ,把 were,had 和 should 放到从句主语前面去,多见于书面语；Had you not helped me , I should have failed. 要是没有你的帮忙,我就失败了；Were you in my position, you would do the same. 假如你处在我的位置,你也会这样干的；Should they a

10、ttack us, well wipe them out completely. 假如他们攻击我们,我们就把他们完全毁灭洁净；三. 含蓄条件句虚拟条件句中的条件从句有时不表出来,只暗含在上下文中,这种句子叫做含蓄条件句；含蓄条件句大体有三种情形；1 条件暗含在短语中；如：But for your help we couldnt have succeeded in the experiment. 假如没有你的帮忙,我们的试验是不会胜利的；暗含在分词短词 but for your help What would I have done without you. 如没有你, 我会怎么办呢？条件暗含在

11、介词短语 without you 中 It would be easier to do it this way. 这样做会比较简单；条件暗含在不定式短语 to do it this way 中 This same thing, happening in wartime, amount to disaster. 同样的事,如发生在战时,就会酿成大祸；条件暗含在分词短语happening in wartime 中 He must have the strength of a hippopotamus, or he never could have vanquished that great bea

13、来是会胜利的；可能暗含 if we had kept trying Your reputation would be ruined. 你的名誉会败坏的；可能暗含if you should accept it 3 在不少情形下,虚拟式已变成习惯说法,很难找出其暗含的条件；如：You wouldnt know. 你不会知道；I would like to come. 我情愿来；四. 不用 if 引导的条件从句虚拟条件句中的条件从句除用if 引外,仍可用when, unless, lest, suppose, as if, for fear, in case, on condition 等词语来引导

16、walking slowly ,as if she were tired. 苏珊走得很慢,就像是累了似的；与 if 一样,上述词语所引导的条件从句亦可用直陈语气,表可能实现或发生的事；虚拟语气补充讲解（其次课时）虚拟语气除主要用于条件句（也就是状语从句）外,仍可用于主语从句、宾语从句、表语从句、定语 从句等；1. 虚拟语气在主语从句中的应用 主语“常用在 It is was+ 形容词 / 过去分词 +that 引导的主语从句”的句型中的主语从句要用虚拟语气；从句的谓语用 should+动词原形 或 should+have+过去分词 或只用动词原形 特别是美国英语 ；should 在此 是助动词

17、,本身并无实义,这种主语从句中的 should 有时有感情颜色；Its important that we （should）work out a plan. （带有 “要求 ” 的含义）Its better that he go at once. （带有 “建议 ”的意思） 用于本句型的形容词并不多,常见形容词有： necessary,important ,best, right, impossible ,preferable,desirable, imperative, advisable ,essential,reserved,urgent, 等；It is necessary that
