高中虛擬語氣講解及練習(xí)題(含答案和解釋)

1、 虛擬語氣講解與練習(xí) 一. 簡(jiǎn)介虛擬語氣用來表示說話人的主觀愿望或假想，而不表示客觀存在的事實(shí)，所說的是一個(gè)條件，不一定是事實(shí)，或與事實(shí)相反。虛擬語氣通過謂語動(dòng)詞的特殊形式來表示。英語中的語氣分為陳述語氣、祈使語氣、虛擬語氣在什么情況下用虛擬語氣? 在表示虛假的、與事實(shí)相反的或難以實(shí)現(xiàn)的情況時(shí)用虛擬語氣，表示主觀愿望或表示某種強(qiáng)烈情感時(shí)，也用虛擬語氣。即當(dāng)一個(gè)人說話時(shí)欲強(qiáng)調(diào)其所說的話是基于自己的主觀想法，而不是根據(jù)客觀實(shí)際，就用虛擬語氣。二. 虛擬語氣在非真實(shí)條件狀語從句中的用法1、真實(shí)條件狀語從句與非真實(shí)條件狀語從句真：eg . If he doesnt hurry up, he will

2、miss the bus. 如果他不快點(diǎn)，他將錯(cuò)過巴士。( 真實(shí)條件狀語)（不是虛擬語氣） If he is free, he will ask me to tell stories. 如果他是空閑的，他會(huì)要求我講故事。（真實(shí)條件狀語）（不是虛擬語氣） 非真：eg. If I were you, I would go at once.如果我是你，我馬上就會(huì)去。 （非真實(shí)條件狀語從句） If there were no air, people would die. 如果沒有空氣，人就會(huì)死亡。（非真實(shí)條件狀語從句）2、用法及動(dòng)詞形式1、表示與現(xiàn)在事實(shí)相反的情況，例1.If I were you,

3、I would take an umbrella.如果我是你，我會(huì)帶把傘。（事實(shí)：我不可能是你） 2.If I knew his telephone number, I would tell you. 如果我知道他的電話號(hào)碼，我就會(huì)告訴你。（事實(shí)：不知道） 3.If there were no air or water, there would be no living things on the earth. 如果沒有水和空氣，地球上就不會(huì)有生物。(事實(shí)：地球上既有空氣也有水) 4.If I had any money with me, I could lend you some. 如果我?guī)?/p>

4、錢了，我就會(huì)借給你些。（事實(shí)：沒帶錢） 5.If he studied harder, he might pass the exam.如果他再努力些，就能通過考試了。（事實(shí)：沒有努力2、表示與過去事實(shí)相反的情況 例：1. If I had got there earlier, I should/could have met her. 如果我早到那兒，我就會(huì)見到她。（事實(shí)：去晚了） 2.If he had taken my advice, he would not have made such a mistake. 如果他聽我的勸告的話，就不會(huì)犯這樣的錯(cuò)誤了。（事實(shí)：沒有聽我的話） 3、表示對(duì)將

5、來情況的主觀推測(cè) 例： 1.If he should come here tomorrow, I should/would talk to him. 如果他哪天來這兒的話，我就跟他談?wù)劇?（事實(shí)：來的可能性很?。?2.If there were a heavy snow next Sunday, we would not go skating. 如果下周日下大雪，我們就不能去滑冰了。（事實(shí)：不知能否下雪） 3.If she were to be there next Monday, I would tell her about the matter. 如果她下周一來這兒的話，我就會(huì)告訴她這件事

6、的始末。 在表示建議、命令、要求等含義的賓語從句，謂語動(dòng)詞常用虛擬語氣，"should動(dòng)詞原形"構(gòu)成，should 可省略。 4、 有時(shí)，主句和條件狀語從句的謂語動(dòng)作若不是同時(shí)發(fā)生時(shí)，虛擬語氣的形式應(yīng)作相應(yīng)的調(diào)整。 從句的動(dòng)作與過去事實(shí)相反，而主句的動(dòng)作與現(xiàn)在或現(xiàn)在正在發(fā)生的事實(shí)不符。如： If I had worked hard at school, I would be an engineer, too. 如果我在學(xué)校學(xué)習(xí)刻苦的話，我現(xiàn)在也會(huì)成為一個(gè)工程師了 If they had informed us, we would not come here now. 如果他

7、們通知過我們的話，我們現(xiàn)在就不會(huì)來這里了，從句的動(dòng)作與現(xiàn)在事實(shí)相反，而主句的動(dòng)作與過去事實(shí)不符。如：If he were free today, we would have sent him to Beijing. 如果他今天有空的話，我們會(huì)已經(jīng)派他去北京了。If he knew her, he would have greeted her. 要是他認(rèn)識(shí)她的話，他肯定會(huì)去問候她了。從句的動(dòng)作與過去發(fā)生的情況相反，而主句的動(dòng)作與現(xiàn)在正在發(fā)生的情況相反。如： If it had not been raining too much, the crops would be growing much b

8、etter. 如果天不下太多的雨的話，莊稼會(huì)長(zhǎng)得更好。 If he had been working hard, he would be working in the office now. 要是他一直努力工作的話，他現(xiàn)在已進(jìn)了辦公室了。 5、 當(dāng)虛擬條件句的謂語動(dòng)詞含有were, should, had時(shí)，if可以省略，這時(shí)條件從句要用倒裝語序，即將were, should, had等詞置于句首，這種多用于書面語。如： Should he agree to go there, we would send him there. 要是他答應(yīng)去的話，我們就派他去。 Were she here, s

9、he would agree with us. 如果她在這兒的話，她會(huì)同意我們的。 Had he learnt about computers, we would have hired him to work here. 如果她懂一些電腦知識(shí)的話，我們已經(jīng)聘用他來這里工作了。 6、非真實(shí)條件句中的條件從句有時(shí)不表達(dá)出來，只暗含在副詞、介詞短語、上下文或其他方式表示出來，這種句子叫做含蓄條件句，在多數(shù)情況下，條件會(huì)暗含在短語中，如without., but for.等 But for his help, we would be working now. 要不是他的幫助，我們還會(huì)在工作呢。 Wit

10、hout your instruction, I would not have made such great progress. 要是沒有你的指導(dǎo)，我不會(huì)取得如此大的進(jìn)步。 We didnt know his telephone number; otherwise we would have telephoned him. 我們不知道他的電話號(hào)碼，否則我們就會(huì)給他打電話。 7、 有時(shí)，虛擬條件句中，主、從句可以省略其中的一個(gè)，來表示說話人的一種強(qiáng)烈的感情。 省略從句 He would have finished it. 他本該完成了。 You could have passed this e

11、xam. 你應(yīng)該能通過這次考試了。 省略主句 If I were at home now. 要是我現(xiàn)在在家里該多好啊。 If only I had got it. 要是我得到它了該多好啊。、虛擬語氣（Subjunctive Mood)的其他用法1、虛擬語氣用在wish 后的賓語從句a、表示與現(xiàn)在事實(shí)相反的愿望，謂語動(dòng)詞用過去式 eg. I wish I had your brains.我希望我有你那樣的頭腦。(事實(shí)：我根本比不上你) b、表示與過去事實(shí)相反的愿望，謂語動(dòng)詞：had+done(動(dòng)詞過去分詞） eg:.I wish I had known the truth of the matt

12、er.我希望我原來知道這件事的真相。（事實(shí)：原來不知道） c、表示將來難以實(shí)現(xiàn)的愿望 謂語動(dòng)詞：should/would + 動(dòng)詞原形 eg. I wish I should have a chance again.我希望我還能有一次這樣的機(jī)會(huì)。（事實(shí)：很難再有這樣的機(jī)會(huì)了） (注：if only和as if/as though也有相同用法）2、虛擬語氣用在目的狀語從句中1.在for fear that, in case, lest引導(dǎo)的，若用虛擬語氣時(shí)，從句謂語為：should + 動(dòng)詞原形。并且 should不能省略 She examined the door again for fear

13、 that a thief should come in. 她又把門檢查了一遍，以防盜賊的進(jìn)入。 He started out earlier lest he should be late. 他很早就出發(fā)了以防遲到。 2、在so that, in order that所引導(dǎo)的目的狀語從句中，從句中的謂語為：can / may / could / might / will / would / should + 動(dòng)詞原形。 He goes closer to the speaker so that he can hear him clearer. 他走近說話的人以便能聽得更清楚。 He read

14、the letter carefully in order that he should not miss a word. 他把信讀得很仔細(xì)以便不漏掉一個(gè)單詞。3、虛擬語氣的其他用法1、一堅(jiān)持(insist)二命令(order. command)三建議(advice. suggest. propose)四要求(demand. require. request. desire.)中，無論主句謂語動(dòng)詞為何種時(shí)態(tài)，從句的謂語動(dòng)詞都用：“should + 動(dòng)詞原形”或只用“動(dòng)詞原形”。 如 He suggested that we (should) take the teachers advice H

15、e insisted that we (should) take the teachers advice He demand that we (should) take the teachers advice He ordered that we (should) take the teachers advice 注：insist如果翻譯成堅(jiān)持某種動(dòng)作才用虛擬語氣翻譯成堅(jiān)持某種觀點(diǎn)就不用虛擬語氣。 如：He insist he is a student. 他堅(jiān)持說他是個(gè)學(xué)生。 這個(gè)語句表示的是事實(shí)，因此在這個(gè)語句中不能使用虛擬語氣。 suggest意為“建議”才用虛擬語氣，意為“暗示”則不用虛

16、擬語氣。 如： His face suggests that he looks worried .他的表情暗含著他很擔(dān)心。 這個(gè)句子本身是事實(shí)，因此它就沒有用到虛擬語氣。 表情緒.觀點(diǎn)的形容詞或名詞也要用虛擬語氣.如:necessary. important. impossible. natural. strange. surprising. funny. right. wrong. better. a pity等。句型：It is.that 結(jié)構(gòu)后的主語從句，從句的謂語動(dòng)詞都要用 should+原型 或只用動(dòng)詞原型。 2、 在even if, even though 所引導(dǎo)的讓步狀語從句中，

17、可用虛擬語氣，主句、從句的結(jié)構(gòu)與if所引導(dǎo)的條件從句結(jié)構(gòu)相同。如： Even if he were here himself, he should not know what to do. 即使他親自來也不知該怎么辦。Nobody could save him even though Hua Tuo should come here. 即使華佗在世也救不了他。 3、 在whatever，whichever，whenever，whoever, wherever，however, no matter wh-word 等引導(dǎo)的讓步狀語從句中，從句虛擬語氣結(jié)構(gòu)為： may +動(dòng)詞原形(指現(xiàn)在或?qū)?。

18、如： We will finish it on time no matter what / whatever may happen. 不管發(fā)生什么事，我們都要按時(shí)完成。 We will find him wherever / no matter where he may be. 無論他在哪里，我們都要找到他。 I will wait for him no matter how late he may come. 不管他來的多么晚，我都會(huì)等他。 may +完成式(指過去) ，主句結(jié)構(gòu)不限。如： You mustnt be proud whatever / no matter what great

19、 progress you may have made. 不管你取得了多么大的進(jìn)步，你也不能驕傲 We must respect him no matter what / whatever mistakes he may have made. 不管他犯過什么錯(cuò)誤，我們必須尊敬他。 4、一般would rather, had rather, would sooner等之后的賓語從句常表示與客觀事實(shí)不相符的一種愿望，故使用虛擬語氣。其虛擬語氣的結(jié)構(gòu)為： 表示所發(fā)生的時(shí)間虛擬語氣結(jié)構(gòu) 過去 had + 過去分詞； 現(xiàn)在 過去時(shí)(be 用were ) 將來 過去時(shí)(be 用were ) 如：Id ra

21、my daughter at school. 我該去學(xué)校接我的女兒了。 It is high time you should go to work. 你早該上班了。 6、 簡(jiǎn)單句中的虛擬語氣 （1） 說話時(shí)，為了表示客氣、謙虛、委婉而有禮貌，言語常使用虛擬語氣。其虛擬語氣的結(jié)構(gòu)形式常為：would / could / might / should + 原形動(dòng)詞。如：Would you mind my shutting the door? 我把門關(guān)起來你介意嗎？You should always learn this lesson by heart. 你要把這個(gè)教訓(xùn)牢記于心。I should a
