1、精品资料欢迎下载虚拟语气在英语文法中有三种语气，即直述式语气(Indicative Mood)、祈使语气(Imperative Mood)和虚拟语气 (Subjective Mood)，其中前两种我们早已熟悉了，这里则不多谈了， 如： How beautiful she is! 则是直述式语气， 而 Hurry up! Dont hurry up 则是祈使语气。 我们主要来看看虚拟语气的主要用法。虚拟语气主要是用来表达一种无法实现的愿望，一种与事实相反的情况，或者将不可能实现的，或可能性很小的事实， 假想为事实予以表述。 这样的动词结构称为虚拟语气。它主要有三种形式， 即与现在事实相反的假设，

9、ome now. It is high time that we left. 1 语法辨析Incorrect: If I was a girl， I would marry you Correct: If I were a girl， I would marry you 表示与现在事实相反的虚拟语气时，if 条件句中的 be动词一律用 were，这句话应译为我要是个女孩，我就嫁给你。实际上不可能是个女孩。Incorrect: If I were you I will not worry Correct: If I were you I shouldnt worry 现在时的虚拟语气主句要用sh
10、ould 或 would 加动词原形，这句话应译为我要是你的话，就没有必要烦恼。 要注意这种语态用在这里实际上是想把要讲出的观点表达得婉转些，有礼貌些。Incorrect: God forgives you! Correct: God forgive you! 这里的主语God 是第三人称单数，之所以动词不加s 是因为要表达一种祝愿，即人力所不能及的事情，实际上是forgive 前有一助动词 should， May 等，但在口语中将其省略了。如：May you be happy 祝你幸福。Incorrect: If the weather was nice yesterday, we woul
11、d have gone to the zoo Correct: If the weather had been nice yesterday ， we would have gone to the zoo 精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 3 页，共 8 页精品资料欢迎下载因句中有yesterday 一词即表示的是与过去相反的事实，即昨天天气很不好，我们也未去动物园，所以if 条件句应用had过去分词。Incorrect: If it is was not snowing right now,I will go for a walk
12、Correct: If it was (were) not snowing right now， I would go for a walk 虚拟语态be 动词作助动词时，则可用was来取代 were， 如 was to。虚拟语态中的动词如果是表示正在进行之中也要用进行时态。Incorrect: If you had taken my advice, you would have been better now Correct: If you had taken my advice, you would be better now 这句话的意思是如果你以前要是能听我的忠告的话，你现在就会好多了
13、。 其条件句是与过去事实相反的虚拟句，而主句是与现在事实相反的虚拟句，这在语法书中叫做混合虚拟条件句。 例如： If I had caught that plane ， I would be dead now 即： The plane I intended to catch crashed and everyone was killed Incorrect: He were you， he would go home at once Correct: Were he you ， he would go home at once Correct: If he were you， he would
14、 go home at once 在虚拟条件句中的 if 可以省略，但 if 省略后其句子的结构要采用倒装语序。Incorrect: Supposing your teacher saw you with me What does she think? Correct: Supposing your teacher saw you with me ， what might she think? 这句话中没有 if 条件句，但仍要用作虚拟语态。这里因为有些分词或介词短语，起到了从句的作用。这些短语有：without， providing, supposing， but for(you)Incor
15、rect: To see the girl， you will like her Correct: To see the girl ， you would like her 这里的条件句是用不定式取代了。Incorrect: Im sorry I did have come here by car Correct: Im sorry I should have come here bycar 这里的条件句被省略了， 其意为我真应该坐小车来。 同样在句意不会混淆的情况下，主句也有时可以被省略， 如： What if we should fail! ( 我们万一失败了如何 )。If he coul
16、d do it, why not? (如果他能做，他怎么会不干呢?) Incorrect: If the earth were (was) to turn from east to west ， I will give you this car as a gift Correct: If the earth were(was) to turn from east to west I would give you this car as a gift 条件句中也常用 were to 来表示说话者认为可能性极小或根本不可能的事。精选学习资料 - - - - - - - - - 名师归纳总结 - -

18、ittle girl looked as if she had seen a ghost 要注意的是as if 从句中如果用虚拟语气， 它的用法要与if 条件句的动词结构相同，即与现在事实相反动词用过去式，be 动词用 were，而与过去事实相反的动词用 hadpp (过去分词 )。另外更要注意的是，并非所有as if 从句都要用虚拟语气。如：Itlooks as if it is going to snow (看天好像要下雪 )即是真实条件句。Incorrect: I should have come here early ， but I had beenbusy Correct: I sh
19、ould have come here early but I wasbusy but 是转折连词，其后的句子是真实句，而不是虚拟句。Incorrect: To tell the truth， I wish I know her address now Correct: To tell the truth, I wish I knew heraddress now wish 的宾语从句中要用虚拟结构，与现在事实相反的条件动词要用过去式，be动词用 were，与过去事实相反的条件动词要用had过去分词。如：I wished I had passed that exam Incorrect: Hi
20、s homework was written badly I wish he will do it better tomorrow Correct: His homework was written badly I wish he would do it better tomorrow wish 要用来表示对现状不满，希望将来有所改进，则要用would 加动词原形。并非 wish 不能表达真正的祝愿，但是不能接从句，而要用双宾语，或不定式，如：I wish you luck (双宾语 ) I wish you to be a good student I wish to see her at
21、once Incorrect: I wish it will not be another failure Correct: I hope it will not be another failure Correct: I wish it would not be another failure 要注意 hope 与 wish 的不同用法。2 例题解析例 1If heon tourists for his business ， he would have to close his shop A dependsB will dependC depended Dhas depended 答案 C这

26、hat hethis work at once A doB doesC didD will do 答案A虚拟语气可以用来表示要求、建议、提议、命令、意愿等。在Itis 形容词 (过去分词 ) 从句的结构中，从句中的谓语动词要用should 加动词原形，其 should在美语中经常省略。这样的形容词有：important， necessary ，strange ， natural。 这样的过去分词有：demanded, requested, suggested， required，recommended 。精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -
