【考点一】非真实条件句的虚拟语气
注意:(1)若条件句中有were,had,should,可把if 省略,而把were,had,should 放在主语前,形成倒装结构,这种结构主要用于书面语中。
Had you taken my advice,you wouldn’t have failed in the examination.如果你听了我的建议,你就不会考试不及格了。
(2)有时主句和虚拟条件从句的动作发生的时间不一致,此时,主句和从句的谓语动词要根据各自所指的不同时间选择适当的动词形式。
If you had worked hard,you would be very tired now.
如果你真的努力工作了,你现在就会感到很累的。(从句指过去,主句指现在)
(3)有时虚拟条件并不通过条件从句表达出来,而是通过词、短语或上下文暗示,此时句子的时态要依具体情况而定。
Without electricity(=If there were no electricity),life would be quite different today.
如果没有电,今天的生活就会完全不同。
But for your help,it would have caused a serious loss.
要不是你的帮助,那将会导致巨大的损失。
I was busy that day.Otherwise I would have gone there with them.(If I hadn’t been busy that day,I would have gone there with them.)我那天很忙,否则,我就和他们一起去那儿了。
【经典考题】
1. If he________my advice,he wouldn’t have lost his job.
A.followed B.should follow
C.had followed D.would follow
解析: 句意为:如果他(当时)接受我的建议,就不会丢掉他的工作了。本题考查虚拟语气。因为if条件句表示与过去事实相反,故采用过去完成时。
答案: C
2.(2011?厦门市质量检查)—Thank you for reminding me of the time,or I ________late yesterday.
—Don’t mention it.
A.should be B.would be
C.will have been D.would have been
解析: 考查虚拟语气。从语 境可知说话人是在谈论昨天的事,因此要使用情态动词would+完成式。谢谢你提醒我时间,不然昨天我就迟到了。
答案: D
3.(2011?山东潍坊质检)________more careful,the mistake would not have been made.
A.If he is B.Had he been
C.Should he be D.If he has been
解 析: 从主句中的would not have been made 可知,这是与过去相反的虚拟语气,因此从句谓语动词用had been 的形式,又因助动词为had时,可将if省掉,had提前,故B项正确。
答案: B
【考点二】名词性从句中的虚拟语气
(1)在名词性从句中,常用来表示命令、建议、要求、愿望等的词后宾语从句和同位语从句中用虚拟语气,形式为:(should)+动词原形。常这样用的动词有:advise 劝告,demand 要求,desire 渴望,command 命令,insist 坚持,prefer 宁愿,urge 主张,order 命令,recommend 推荐,request 要求,require 要求,suggest 建议,以及这些词的名词形式。
Jane’s pale face suggested that she was ill,and her parents suggested that she (should)have a medical examination.
简苍白的脸色表明她生病了,她父母建议她做一下医学检查。
(2)wish后面所跟宾语从句中的虚拟语气。
表示对现在情况的虚拟:wish+主语+动词过去式或were
表示对过去情况的虚拟:wish+主语+had+过去分词
表示对将来情况的虚拟:wish+主语+would+动词原形
I wish she were here.她在这儿就好了。
I wish you would go with us tomorrow.
但愿你明天跟我们一块去。
I wish she had taken my advice.
那时她要是听我的话就好了。
【经典考题】
1. Teachers recommend parents________their children under 12 to ride bicycles to school for safety.
A.not allow B.do not allow
C.mustn’t allow D.couldn’t allow
解析: 句意为:为了安全起见,老师建议家长不要让12岁以下的孩子骑自行车上学。本题 考查虚拟语气用法。recommend,suggest,insist,order,request,advise等表“建议、命令、要求”等意思的动词,后接宾语从句时,宾语从句的谓语动词常用“should+动词原形”,should 可以省略。
答案: A
2.(2011?山东潍坊质量抽样)The order came that the medical supplies ________to Beijing for the H1N1 flu soon.
A.would be sent B.should send
C.be sent D.must be sent
解析: 当表示愿望、请求、建议、命令等意义的动词(如order,suggest,command等)后面接从句时,从句用虚拟语气。从句谓语用should+do,should可以省略。order后的同位语从句也用虚拟语气,故选C项。
答案: C
【考点三】其他句型中的虚拟语气
(1)would rather 句型中的虚拟语气表示愿望,意为“宁愿,但愿”。
I’d rather we didn’t go to see a film this evening.
我倒希望我们今晚不去看电影。
(2)It is(high/about)time(that)...句型中的虚拟语气
在句型“It is (high/about)time...”后面也可跟虚拟语气,从句中常用过去式。有时也用“should+动词原形”,意为“该是……的时候了”。
It is time (that)we went home.我们该回家了。
(3)if only 引导的感叹句中的虚拟语气
在“if only”引导的感叹句中,要求用虚拟语气,表示愿望。用过去时或“would/could+动词原形”表示与现在或未来事实相反的愿望;用过去完成时表示与过去事实相反的愿望。
If only I had not been ill last week!
要是上周我没病该多好啊!
【经典考题】
1. —Sorry,Daddy.I am not getting on well with my studies.
—Well.________you hadn’t wasted so much time playing online games.
A.As if B.Even if
C.If only D.Only if
解析: 考查虚拟语气。句意为:——爸爸,对不起,我的学习情况不太好。——哦,要是你不把那么多的时间浪费在网络游戏上就好了。if only(但愿)接虚拟语气,表示对过去情况的假设。as if好像,even if即使,only if只有,都是状语从句的连词,不符合语意。
答案: C
2. (2011?青岛一模)—My uncle suggests I________abroad.
—I would rather you________at home.
A.go;stay B.went;stayed
C.go;stayed D.went;stay
解析: suggest当“建议”讲时,从句中要用虚拟语气,结构是“should+动词原形”,should可以省略。would rather后面跟从句时,从句中也要用虚拟语气,根据语境此处应用过去时。
答案: C
