虚拟语气的用法总结语气:语气是动词的一中形式,它表示说话人对某一行为或事情的看法和态度。
虚拟语气表示动作或状态不是客观存在的事实,而是说话人的主观愿望,假设或推测等。
如If I were you, I should study English.一.虚拟语气在条件从句的用法条件句有两类,一类是真实条件句;一类是非真实条件句,也就是虚拟条件句。
如果假设的情况是有可能发生的,就是真实条件句,谓语要用陈述语气。
如If it doesn’t rain tomorrow, we will go to the park.如果假设的情况是过去或现在都不存在的,或将来不大可能发生的,则是虚拟条件句。
如If he had seen you yesterday, he would have asked you about it. 在含有虚拟条件句的复合句中,主句If her mother had taken the doctor’s advice, she would/might have got well earlier.If it were to rain tomorrow, the match would be canceled.有时候省略if,采用局部倒装语序。
把had /should/were 等动词(不包括行为动词)移到从句的句首。
例如:Were it to rain tomorrow, our picnic would be canceled.Had it not been for the storm, we would have arrived in time.Should the earth stop running, what would happen?二. 错综时间条件句有时条件从句的动作和主句动作发生的时间不一致,这时需要根据意思采用表示不同时间的动词形式来进行调整。
If she had taken the doctor’s advice, she might still be alive.If I were you, I would have accepted their terms.三.含蓄条件句1.有时候假设的情况并不用条件从句表示出来,而是通过介词短语来表示。
如Without air(If there were no air), there would be no living things.But for your help (If it hadn’t been for your help), I couldn’t have done it.2. 假设的条件通过上下文表现出来。
I would go abroad for further study but that I am poor.I was ill that day. Otherwise I would have taken part in the party.3. 表示虚拟语气的主句或从句有时可以省略,但其含义仍可以推知。
(1)省去条件从句You could have washed your clothes yourself. (你本可以自己洗衣服的。
)省去了If you had wanted to。
(事实是:你自己没洗衣服,因为你不想洗。
)(2)省去主句(常用以表示愿望)If my grandmother were with me! (如果我的祖母和我在一起多好啊!)事实是:祖母已不在世。
四、虚拟语气在名词性从句中的应用①“wish+宾语从句”表示不可能实现的愿望,汉语可译为“可惜……、悔不该……、但愿……”。
表示现在不能实现的愿望,从句的谓语动词用过去式;表示将来不可能实现的愿望用“would/could+动词原形”;表示过去不可能实现的愿望时用“had+过去分词”。
如:I wish I were better-looking. 要是我长得再漂亮些就好了。
I wish I had met the film star just now. 我要是刚才遇到那位电影明星该多好啊!I wish I would be a solider. 我想当一名军人。
【考例】How I wish every family ____ a large house with a beautiful garden! (上海2002春)A. hasB. hadC. will haveD. had had②在表示建议、要求、愿望、命令、坚持、想法(advise, command, demand, decide, desire, insist, order, prefer, propose, request, require, suggest)等动词后面的宾语从句,或这些动词的同源名词后面所跟的同位语从句或表语从句中,从句谓语用“should+动词原形”,其中在美国英语中,should常省略。

【考例】Teachers recommend parents_______ their children under 12 to ride bicycles to school for safety. (福建2010)A. not allowB. do not allowC. mustn’t allowD. couldn’t allow③在would rather后的宾语从句中,谓语常常用过去时来表示现在或将来的情况,用过去完成时表示过去的情况。

【考例】George is going to talk about the geography of his country, but I’d rather he _______ more on its culture. (江苏2010)A. focusB. focusedC. would focusD. had focused④在It is +形容词(important, necessary, good, right, wrong, better, natural, proper, funny, strange, surprising) +that从句中,谓语动词的虚拟语气用“(should)+动词原形”的结构。
如:It is natural that she (should) do so. 很自然她应该这样做。
【考例】—Don’t you think it necessary that he _______ to Miami but to New York?— I agree, but the problem is _______ he has refused to. (江苏2005)A. will not be sent; thatB. not be sent; thatC. should not be sent; whatD. should not send; what五、虚拟语气在状语从句中的应用1. if only的条件状语从句中的虚拟语气if only 与I wish一样,也用于表示与事实相反的愿望,其后所接虚拟语气的时态与wish 后所接时态的情况相同。
如:If only the player had had more courage! 这位选手再多有一些勇气就好了。
If only Daisy would go with me! 黛茜要是愿意和我一起去就好了!【考例】Look at the trouble I am in! If only I _______ your advice. (上海2003春)A. followedB. would followC. had followedD. should follow2. as if (as though)方式状语从句中的虚拟语气as if (as though)引导的方式状语从句可用陈述语气,也可用虚拟语气。

③从句表示将来发生的可能性不大,谓语动词用“would (could, might)+动词原形”。
如:It looks as if it might snow. 看起来好像要下雪了。
3. 目的状语从句中的虚拟语气(1)以in order that, so that引导的目的状语从句中,谓语多用could/might+动词原形,在口语中常用can/could+动词原形She took a taxi so that she could get there on time.(2)以lest, for fear that和in case 引导的目的状语从句中,谓语动词多用(should)+动词原形。
She took an umbrella with her lest/for fear that/in case it should rain.六.其他形式的虚拟语气1. It’ s time that句型中的虚拟语气在It’ s time that句型中,从句谓语通常用一般过去时或should+动词原形(should不能省略),其意为“(早)该做某事了”。
