2023届中考英语虚拟语气专题复习 篇1
虚拟语气是通过特殊的谓语动词形式来表达的愿望、假设、怀疑、猜测或建议等语气,它不表示客观存在。
1、虚拟语气用于条件状语从句中
(1)表示与现在事实相反的假设,条件状语从句中的谓语动词用“过去式(be动词的过去式用were)”,而主句中的谓语动词用“would / should/ could / might + 动词原形”。如:
if i were a boy, i would join the army.
if the had time, she should go with you.
(2)表示与过去的事实相反,条件状语从句中的谓语动词用过去完成时,主句中的谓语动词则用“would / should / might / could + have +过去分词”。如:
if he had taken my advice, he would have succeeded in the competition.
(3)表示与将来事实相反,条件状语从句中的谓语动词一般过去时或should(were to) + 动词原形,而主句中的谓语动词则用would / should/could might + 动词原形。如:
if it were to rain tomorrow, the football match would be put off.
(4)当条件状语从句表示的行为和主句表示的行为所发生的时间不一致时,动词的形式要根据它所表示的时间作相应调整。如:
if they had worked hard, they would be very tired.(从句说的是过去,主句指的是现在)
以下表格是虚拟语气用于条件状语从句中时,主句和从句谓语动词的形式:
条件状语从句 主句 与过去事实相反 had + 过去分词 should /would/could/might + have + 过去分词 与现在事实相反 一般过去时(be用were) would/should/could/might + 动词原形 与将来事实相反
一般过去时或should(were to) + 动词原形
would/should/cold/might + 动词原形
有时侯在使用时可省略if,句子则可换成下列形式,即“were / had / should +主语”。如:
were i a boy, i would join the army.
had he taken my advice, he would have succeeded.
were it not for the expense, i would go to britain.
2、虚拟语气用于名词性从句
(1)虚拟语气在宾语从句中的运用。
①“wish + 宾语从句”表示不能实现的愿望,译为“要是……就好了”等。表示现在不能实现的愿望,从句中的谓语动词用一般过去时;表示将来不能实现的愿望,从句中的谓语动词用“would/could + 动词原形”;表示过去不能实现的愿望,从句中的谓语动词用“had + 过去分词”或“could(should) + have + 过去分词”。如:
i wish it were spring all the year round.
i wish i had known the answer.
i wish i could fly like a bird.
②在表示建议、要求、命令等的动词suggest、advise、propose、demand、require、insist request、command、order等后的宾语从句中,谓语动词用should + 动词原形或是动词原形。如:
she suggested we (should)leave here at once.
the doctor ordered she should be operated.
(2)虚拟语气在同位语从句和表语从句中的运用。
作表示建议、要求、命令等的名词advise、idea、order、demand、plan、proposal、suggestion、request等的表语从句和同位语从句,从句中的谓语动词用“(should) + 动词原形”。如:
his suggestion that we (should)go to shanghai is wonderful.
my idea is that they (should)pay 100 dollars.
(3)虚拟语气在主语从句中的运用。
在主语从句中,谓语动词的虚拟语气用“should + 动词原形”的结构,表示惊奇、不相信、理应如此等。如:
it is necessary(important, natural, strange, etc.)that we should clean the room every day.
it was a pity (a shame, no wonder, etc.)that you should be so careless.
it will be desired(suggested, decided, ordered, requested, proposed, etc.)that she should finish her homework this afternoon.
注意:这种从句表示的是事实。如果说人对这种事实表现出惊奇的情感,就可用虚拟语气。反之,如果不表示惊奇等情感,that从句也可用陈述句语气。如:
it is pity that you can’t swim.
3、虚拟语气在其他场合的运用
(1)虚拟语气在as if/as though、even if/even though等引导的表语从句或状语从句中,如果从句表示的动作发生在过去,用过去完成时;指现在状况,则用一般过去时;指将来状况则用过去将来时。如:
he did it as if he were an expert.
even if she were here, she could not solve the problem.
(2)虚拟语气用于定语从句中。
这种从句常用于句型“it is (high)time (that) … ”中,定语从句的谓语动词用一般过去时(be用were)或should + 动词原形,意思是“(现在)该……”。如:
it’s time that i picked up my daughter.
it’s high time we were going.
(3)虚拟语气用在if only引导的感叹句中。如:
if only i were a bird.
if only i had taken his advice.
(4)虚拟语气在一些简单句中的运用。
①情态动词的过去式用于现在时态时,表示说话人谦虚、客气、有礼貌或语气委婉,常出现在日常会话中。如:
it would be better for you not to stay up too late.
would you be kind enough to close the door?
②用于一些习惯表达法中。如:
would you like a cup of tea?
i would rather not tell you.
4、精典名题导解
1. when a pencil is partly in a glass of water, it looks as if it _______. (nmet 95)
a. breaks b.has broken c.were broken d.had been broken
解析:答案为c。本题考查的是as if 引导的让步状语从句中的语气问题,as if引导的状语从句如果与事实一致,不用虚拟语气,如果与事实相反,应用虚拟语气。题中“当铅笔的一部分浸在水中,铅笔看上去好像断了”。而实际上铅笔并未断,与事实相反,前半部分陈述是一般现在时,因而本句是对一般现在时的虚拟,用were broken。
2. i didn’t see your sister at the meeting. if she ___________, she would have met my brother.(nmet 94)
a. has come b.did come c.came d.had come
解析:答案为d。本题考查的是if条件句中的虚拟语气。题意是:我在会议上没看到你姐姐,故你姐姐没来。因此如果“她来了”与事实相反,前面一句交代了虚拟语气的时态是一般过去时的虚拟,所以if从句中用had+过去分词。
3. ―if he ___________, he ________that food.
―luckily he was sent to the hospital immediately.(nmet 93)
a. was warned; would not take
b.had been warned; would not have taken
c.would be warned; had not taken
d.would have been warned; had not taken
解析:答案为b。本题考查的是条件状语从句与主句表示与事实相反时虚拟语气的用法。根据下一句语境可知,他事先并没有得到警告,表示过去时间的虚拟语气,故选b。
4. if there were no subjunctive, english ______ much easier. (nmet)
a. will be b.would have been c.could have been d.would be
5. the guard at the gate insisted that everybody ______ the rules. (nmet)
a. obeys b.obey c.will obey d.would obey
解析:根据insist后的宾语从句谓语要用(should) do形式规律,可定正确答案是b。
6. i wish i _____ you yesterday.
a. seen b.did see c.had seen d.were to see
解析:此题表与过去事实相反的原望,答案应为c。
7. ―― if he _____ , he _____ that food.
―― luckily he was sent to the hospital immediately. (nmet)
a. was warned;would not take b.had been warned;would not have taken
c.wuld be warned;had not taken d.would have been warned;had not taken
解析:从对话看,是表达与过去事实相反的虚拟语气,故答案为b。
8. without electricity human life _____ quite different today. (nmet)
a. is b.will be c.would have been d.would be
解析:without引出一个含蓄条件句,主句表述的是与现在事实相反的虚拟语气,故答案为d。
9. when a pencil is partly in a glass of water, it look as if it _____. (nmet)
a .breaks b. has broken c. were broken d .had been broken
解析:放入水中的铅笔看上去是断的,但实际上并非如此,因此是与现在的事实相反,这时as if从句谓语要用一般过去时,故答案为c。
10. i didn he _____ , he would have said hello to me.
a .would come b. had come c. came d.did come
解析:观察题目上下文,特别是第二句的主句谓语为 would have said,可知if从句表述的是与过去事实相反的愿望,因此答案为b。
11. _____ it _____ for your help, i couldn have made any progress.
a .had;not been b . should ;not be c .did ;not be d .not ;be
解析:根据主句谓语形式,可知从句要用had done形式,故应选a,had it not been for your help=if it had not been for your help.(要不是你帮忙的话)
12. mr smith was badly ill, or he _____ our dinner party.
a. should come to b. would have attended
c. would come to d. should have attended
解析:or可引导含蓄条件句,表达虚拟语气。根据此题内容,可知是与过去事实相反的假设,故答案为b。
2023届中考英语虚拟语气专题复习 篇2
虚拟语气
虚拟语气(subjunctive mood)这一语法项目是各类英语考试中心测试的重点之一。虚拟语气是一种特殊的动词形式,用来表示说话人所说的话并不是事实,而是一种假设、愿望、怀疑或推测。
用以表示虚拟条件的虚拟语气
⒈ 用if条件从句表示的虚拟条件,是虚拟条件最普通的方式。
① 虚拟现在时表示与现在事实相反的假设,其if 从句的谓语形式用动词的过去式(be 一般用were),主句用would/ should/ could/ might +动词原形,例如:if i were in your position i would marry her.
② 虚拟过去时是表示与过去事实相反的假设,if 从句的谓语形式用过去完成时即had+过去分词,主句用would / should / could / might + have +过去分词,例如:if it had not rained so hard yesterday we could have played tennis.
③ 大多数的虚拟条件句属于上面三种情况的一种,但并不排除存在条件和后果中,一个和现在情况相反,另一个和过去情况相反,例如:if you had followed what the doctor said, you would not have been so painful now.这个句子在高中出现频率颇高。
④ 但是,如果后果用了虚拟语气,而条件却用陈述语气,这种用法是错的。
⒉ 除了表示虚假条件外,if从句还可以表示对将来的推测,由于是将来还没有发生的,所以谈不上是真实的还是虚假的,只能说这个事情发生的可能性有多大。一般情况下,可以用陈述语气的if从句来表示对一个未来事实的推测,这个事实是完全可能发生的。if从句的谓语形式用一般过去式或用were to / should +动词原形,主句用would / should /could/ might +动词原形,例如:jean doesn't want to work right away because she thinks that if she were to get a job she probably wouldn't be able to see her friends very often.(1996年1月四级第44题)
⒊ 有时可以把含有助动词、情态动词、be或have的虚拟条件句中的连词if 省去,而将had , should, were 等词提到主语之前,即用倒装结构,这时候,如果出现not等否定词,否定词需放在主语后面。这种结构在口语中很少使用,但频频出现在各类考试中出现,例如:if it had not rained so hard yesterday we could have played tennis.→had it not rained so hard yesterday, we could have played tennis.
⒋ 大多数的虚拟条件通过上面所讲的两种方法表达,但在个别句子中也可以通过介词without和介词短语but for表达,副词otherwise等表达出来。例如:we didn't know his telephone number; otherwise we would have telephoned him.(1995年6月四级第46题)值得注意的是,包含but for的句子,谓语动词必定要用虚拟形式,但包含without等短语的句子,谓语动词未必一定要用虚拟语气。
⒌ 有时虚拟条件不是明确地表达出来,而在蕴含在用but引导的从句里,于是便出现了有谓语动词是虚拟语气的主句加上谓语动词是陈述语气的but从句构成的并列复合句,例如i would have hung you but the telephone was out of order.在这样的句子里,如果主句没有用虚拟语气,或者从句用了虚拟语气,都是错的。
用在宾语从句中的虚拟语气
⒈ 在表示愿望的动词wish后的宾语从句中,需用虚拟语气。(wish后的that 常省略),根据主句时态,从句谓语时态相应退后一位,例如:how she wished his family could go with him.
⒉ 在具有愿望、请求、建议、命令等主观意愿的动词(desire, demand, advice, insist, require, suggest, propose, order, recommend, decide …) 后的宾语从句中需用虚拟语气。谓语动词用(should) +动词原形。值得注意的是,如果宾语从句的动词是否定的,否定词not的位置应在动词之前,而不是动词之后。例如:the head nurse insisted that the patient not be move.另外,如suggest表达“暗示”,insist表示“坚持某种说法”时,后面的从句不用虚拟语气,例如:her pale face suggests that she is ill.或he insisted that he did not kill the boy.
除此之外,上述动词也要求用虚拟式
① 在it is+上述动词的过去分词,其后所跟的主语从句中,如it is suggested that pupils wear school uniforms.
② 在上述动词相应的名词形式作主语+连系动词,其后的表语从句中,例如his suggestion was that classed be re-scheduled.
③ 在对上述动词相应的名词进行解释的同位语从句中,如:the workers raised the demand that their pay be increased to cope with the inflation.
⒊ would (had)rather , would sooner也用来表达主观愿望,它们之后的宾语从句中需用虚拟语气。谓语动词用过去式表示现在或将来,用过去完成式表示与过去事实相反,例如:i would rather he went right now.
其他形式的虚拟语气
⒈ it is +necessary等形容词后,that主语从句中虚拟形式使用,这类形容词包括necessary, important, essential, imperative, urgent, preferable, vital, advisable等,例如it is necessary that you listen to the teacher carefully.或者it is essential that you be able to pronounce every single word correctly.
⒉ 在it's (high/about) time 之后的定语从句中需用虚拟语气。谓语动词用过去式,例如it is high time that you went to school
⒊ 虚拟语气在as if / as though 引导的方式状语从句中的应用(谓语动词形式与wish后的宾语从句基本相同)表示与现在事实相反或对现在情况有怀疑,谓语动词用过去式。例如:he felt as if he alone were responsible for what had happened. 表示过去想象中的动作或情况,谓语动词用过去完成式。
⒋ 在lest 引导的状语从句中,谓语动词多用虚拟语气,(should )+ 动词原形。例如: the mad man was put in the soft-padded cell lest he injure himself.(1998年1月四级第38题)
⒌ 在if only 引起的感叹句中需用虚拟语气。谓语动词用过去式或过去完成式。例如: look at the terrible situation i am in! if only i had followed your advice.
