虛擬語氣 (2).doc

虛擬語氣一、 應(yīng)用條件在表示虛假的、與事實相反的或難以實現(xiàn)的情況時用虛擬語氣，表示主觀愿望或某種強(qiáng)烈情感時，也用虛擬語氣。即當(dāng)一個人說話時欲強(qiáng)調(diào)其所說的話是基于自己的主觀想法，而不是根據(jù)客觀實際，就用虛擬語氣。 二、 在非真實條件狀語從句中的用法真實條件狀語從句與非真實條件狀語從句條件句可分為兩類，一類為真實條件句，一類為非真實條件句。非真實條件句表示的是假設(shè)或?qū)嶋H可能性不大的情況，故采用虛擬語氣。 eg： If he doesnt hurry up,he will miss the bus.如果他不快點，他將錯過巴士。( 真實) If he is free, he will ask me to tell stories.如果他是空閑的，他會要求我講故事。（真實） If I were you, I would go at once.如果我是你，我馬上就會去。 （我不是你。非真實，虛擬語氣） If there were no air, people would die.如果沒有空氣，人就會死亡。（不可能沒有空氣。非真實，虛擬語氣） 用法及動詞形式1、表示與現(xiàn)在事實相反的情況： 從句：主語+過去時 主句：主語+should/would/could/might+do eg： 1.If I were you, I would take an umbrella. 如果我是你，我會帶把傘。（事實：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碼，我就會告訴你。（事實：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，地球上就不會有生物。(事實：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)уX了，我就會借給你些。（事實：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：沒有努力） 2、表示與過去事實相反的情況 從句：主語+had done 主句：主語+should/would/could/might+have done eg： 1. If I had gotten there earlier, I should/could have met her. 如果我早到那兒，我就會見到她。 （事實：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，就不會犯這樣的錯誤了。 （事實：沒有聽我的話） 3、表示對將來情況的主觀推測 從句：if+主語+were to do 主句：主語+should/would/could/might+do if+主語+did/were 主語+should/would/could/might+do if+主語+should+do 主語+should/would/could/might+do eg： 1.If he should come here tomorrow, I would talk to him. 如果他明天來這兒的話，我就跟他談?wù)劇?（事實：來的可能性很小） 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：不知能否下雪） 3.If she were to be here next Monday, I would tell her about the matter. 如果她下周一來這兒的話，我就會告訴她這件事的始末。 4、 有時，虛擬條件句中，結(jié)果主句和條件從句的謂語動作若不是同時發(fā)生時，虛擬語氣的形式應(yīng)作相應(yīng)的調(diào)整。 從句的動作與過去事實相反，而主句的動作與現(xiàn)在或現(xiàn)在正在發(fā)生的事實不符。 eg： 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)在也會成為一個工程師了 If they had informed us, we would not come here now. 如果他們通知過我們的話，我們現(xiàn)在就不會來這里了。 從句的動作與現(xiàn)在事實相反，而主句的動作與過去事實不符。 如： If he were free today, we would have sent him to Beijing. 如果他今天有空的話，我們會已經(jīng)派他去北京了。 If he knew her, he would have greeted her. 要是他認(rèn)識她的話，他肯定會去問候她了。 5、 當(dāng)虛擬條件句的謂語動詞含有were, should, had時，if可以省略，這時條件從句要用倒裝語序，即把were, should, had等詞置于句首，這種多用于書面語。 eg： 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, she would agree with us. 如果她在這兒的話，她會同意我們的。 Had he learnt about computers, we would have hired him to work here. 如果他懂一些電腦知識的話，我們已經(jīng)聘用他來這里工作了。 6、非真實條件句中的條件從句有時不表達(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，條件會暗含在短語中，如without, but for等 eg： But for his help, we would be working now. 要不是他的幫助，我們還會在工作呢。 Without your instruction, I would not have made such great progress. 要是沒有你的指導(dǎo)，我不會取得如此大的進(jìn)步。 We didnt know his telephone number, otherwise we would have telephoned him. 我們不知道他的電話號碼，否則我們就會給他打電話。 7、 有時，虛擬條件句中，主、從句可以省略其中的一個，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 exam. 你本該通過這次考試的。 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. 要是只有我得到它了該多好啊。 8.注意，在虛擬語氣的從句中，動詞be的過去時態(tài)一律用were，不用was。 eg：If I were you,I would go to look for him. 如果我是你，就會去找他。 三、 虛擬語氣（Subjunctive Mood)的其他用法用在wish 后的賓語從句a、表示與現(xiàn)在事實相反的愿望，謂語動詞用過去式 eg. I wish I had your brains. 我希望我有你那樣的頭腦。(事實：我根本比不上你) b、表示與過去事實相反的愿望，謂語動詞：had+done eg:.I wish I had known the truth of the matter. 我希望我那時就知道這件事情的真相。（事實：那時還不知道） c、表示將來難以實現(xiàn)的愿望 謂語動詞：should/would + 動詞原形 eg. I wish I should have a chance again. 我希望我還能有一次這樣的機(jī)會。（事實：很難再有這樣的機(jī)會了） (注：if only和as if/as though也有相同用法） 用在目的狀語從句中1、在for fear that, in case, lest引導(dǎo)的從句中，若用虛擬語氣時，從句謂語為：should + do.并且 should不能省略 She examined the door again for fear 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. 他早早的就出發(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 / could / may / might / will / would / should + do。 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 the letter carefully in order that he should not miss a word. 他把信讀得很仔細(xì)以便不漏掉一個字。 其他用法1、一想要(desire)二寧愿(prefer)三命令(order. command)四建議(advice. suggest. propose)五要求(demand. require. request. desire.insist)中，無論主句謂語動詞為何種時態(tài)，從句的謂語動詞都用：should + do。should可以省略。eg： He suggested that we (should) takethe teachers advice. He insisted that we (should) takethe teachers advice. He demand that we (should) takethe teachers advice. He ordered that we (should) takethe teachers advice. insist意為“堅持某種動作”才用虛擬語氣；意為“堅持某種觀點，某個事實”則不用虛擬語氣。 eg： He insists he is a student. 他堅持說他是個學(xué)生。 這個語句表示的是事實，因此在這個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”則不用虛擬語氣。 eg： His face suggests that he looks worried . 他的表情暗含著他很擔(dān)心。 這個句子本身是事實，因此它就沒有用到虛擬語氣。 2、表情緒.觀點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 +主語從句，從句的謂語動詞都要用should+原型 或只用動詞原型。 eg: Do you think it necessary that he (should) not be sent to Lingbao. It is srange that such a person should be our friend. 奇怪的是這樣一個人會成為我們的朋友。 注：這一點還沒有準(zhǔn)確的說法，希望善心人能把這點補(bǔ)充完全。 3、 在even if, even though 所引導(dǎo)的讓步狀語從句中，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。 eg： 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。（事實：他沒來） Nobody could save him even though Hua Tuo should come here. 即使華佗在世也救不了他。（事實：華佗不在世） 4、 在whatever，whichever，whenever，whoever, wherever，however, no matter wh-等引導(dǎo)的讓步狀語從句中，從句虛擬語氣結(jié)構(gòu)為： 指現(xiàn)在或?qū)恚?may +do。 eg： We will finish it on time no matter what may happen. 不管發(fā)生什么事，我們都要按時完成。 We will find him wherever 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，我都會等他。 指過去： may +have done 。 eg： You mustnt be proud whatever great 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 mistakes he may have made. 不管他犯過什么錯誤，我們必須尊敬他。 5、一般would rather, had rather, would sooner等之后的賓語從句常表示與客觀事實不相符的一種愿望，故使用虛擬語氣。其虛擬語氣的結(jié)構(gòu)為： 過去 had + done 現(xiàn)在 過去時(be 用were ) 將來 過去時(be 用were ) eg： Id rather you had seen the film yesterday. 我倒想你昨天看過了這場電影。 Id rather you were here now. 我倒想你現(xiàn)在在這兒。 Wed rather you went here tomorrow. 我們倒想你明天去那兒 注：注意would rather，had rather，would sooner的細(xì)微差別，可以百度一下查查。 6、虛擬語氣還可用在定語從句中，表示：“早該做某事了”時，定語從句中的謂語動詞須用虛擬語氣，其虛擬語氣的結(jié)構(gòu)為：It is (high / about) time that + 主語+ 動詞的過去式/ should + do，即從句用虛擬過去式。 It is time that I went to pick up 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。 7、 簡單句中的虛擬語氣 （1） 說話時，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 +do。 eg： Would you mind my shutting the door? 你介意我把門關(guān)起來嗎？ You should always learn this lesson by heart. 你要把這個教訓(xùn)牢記于心。 I should agree with you. 我本該同意你的觀點。（委婉的不同意） （2） 表示“祝愿”時，常用may + 主語+ do。 eg： May you have a good journey! 祝你一路順風(fēng)。 May your youth last for ever! 祝你青春永駐。 （3）表示強(qiáng)烈的“愿望”、“祝愿”時，常用do。 eg： Long live the Communist Party of China. 中國共產(chǎn)黨萬歲。 God bless us. 上帝保佑。 （4） 習(xí)慣表達(dá)中常用的虛擬語氣。 提出請求或邀請。eg： Would you like to have a talk with us this evening? 今天晚上來跟我們聊天好嗎？ Could I use your bike now? 我可以用一下你的單車嗎？ 陳述自己的觀點或看法。eg： I should glad to meet you. 見到你我會很高興。 I would try my best to help you. 我會盡力幫助你。 提出勸告或建議。eg： Youd better ask your father first. 你最好先問一問你的父親。 You should make a full investigation of it first. 你應(yīng)該先全面調(diào)查一番。 提出問題。eg： Do you think he could get here on time? 你認(rèn)為他能按時來嗎？ Do you expect he would tell us the truth? 你期望他會告訴我們真相嗎？ 表示對過去情況的責(zé)備時，常用虛擬語氣。其虛擬語氣的結(jié)構(gòu)為：情態(tài)動詞 + have done。 eg： You should have got here earlier. 你早該到這里了。 You should have returned it to him. 你早該把它還給他了。 8、虛擬語氣在方式狀語從句的應(yīng)用。as if, as though 兩者的意義和用法相同，引出的表語從句和方式狀語從句謂語多用虛擬語氣，表示與事實相反；有時也用陳述語氣，表示所說情況是事實或?qū)崿F(xiàn)的可能性較大。漢譯常作仿佛似的，好像似的四、省略的虛擬條件句型省略連詞if有時可將條件從句的連詞if省略，但此時應(yīng)用倒裝句型，即把從句中的were, should, had 等提到句首： Were I Tom, I would refuse. 如果我是湯姆，我會拒絕。 Should it be necessary,I would go. 假若有必要，我會去的。 Had it not been for the bad weather we would have arrived on time. 若不是天氣壞，我們就準(zhǔn)時到達(dá)了。 【注】 若條件從句為否定句，否定詞not應(yīng)置于主語之后，而不能與were, should, had 等縮略成Werent, Shouldnt, Hadnt而置于句首。 有時省略if后提前的had不是助動詞： Had I time, I would come. 假若我有時間，我會來的。(=If I had time) 省略條件句的主語和其后的動詞be若主從句主語一致，且謂語部分包含有動詞be，通?？蓪⒅髡Z和動詞be省略： If repaired earlier, the tractor would not have broken down. 要是早點兒修一下，拖拉機(jī)就不會拋錨了。(=If it had been repaired earlier) 省略“it+be”If necessary, I would send more farmhands to help you. 如果需要的話，我會派更多的人去幫你。(=If it was necessary,) 省略整個條件從句這樣的省略通常需要借助一定的上下文，即省略條件從句后，所剩下的主句的意思在一定的上下文中意思是清楚的： I might see her personally. It would be better. 我可以親自去看她，這樣好一些。(=If I saw her personally, it would be better.) 五 、在含蓄條件句中的用法(1) 條件暗含在
