虛擬語(yǔ)氣Ⅱ教學(xué)案 于亞?wèn)| 　　虛擬語(yǔ)氣除主要用于條件句（也就是狀語(yǔ)從句）外，還可用于主語(yǔ)從句、賓語(yǔ)從句、表語(yǔ)從句、定語(yǔ)從句等。 1. 虛擬語(yǔ)氣在主語(yǔ)從句中的應(yīng)用 　　“常用在It is (was)+形容詞 / 過(guò)去分詞+that引導(dǎo)的主語(yǔ)從句”的句型中的主語(yǔ)從句要用虛擬語(yǔ)氣。主語(yǔ)從句的謂語(yǔ)用should+動(dòng)詞原形(或should+have+過(guò)去分詞)或只用動(dòng)詞原形(尤其是美國(guó)英語(yǔ))。should在此是助動(dòng)詞，本身并無(wú)實(shí)義，這種主語(yǔ)從句中的should有時(shí)有感情色彩。 　　Its important that we（should）work out a plan. （帶有“要求”的含義） 　　Its better that he go at once. （帶有“建議”的意思） 　　☆ 用于本句型的形容詞并不多，常見(jiàn)形容詞有：necessary，important，best, right, impossible，preferable，desirable, imperative, advisable，essential，reserved，urgent， 等。 　　It is necessary that he（should）be sent there at once．　　 　　Its strange that he should say so.　 　　I was glad that he should go. 　　It is important that we should speak politely. 　　It is a pity that she should fare so badly. 　　Its right that you should think that way. 　　 　　☆ 用于本句型中的過(guò)去分詞就是表示提議、要求、命令等動(dòng)詞的過(guò)去分詞，如suggested，settled, required，requested，demanded，urged，decided, proposed，ordered，desired，advised等。 　　It is requested that Professor Liu（should）give us a lecture．　　 　　It is desired that we（should）get everything ready by tonight． 　　I’m ashamed you should have done such a thing. 　　It has been suggested that the meeting（should）be put off．有人建議推遲會(huì)議。 　　It is settled that you leave us, then? 　　 　　注意：這種句型中的主語(yǔ)從句也可用陳述語(yǔ)氣，如：It was important that he made an explicit statement on this score last week. 他上個(gè)星期對(duì)于這一方面做了明確的說(shuō)明，這是很重要的。 2. 虛擬語(yǔ)氣在賓語(yǔ)從句中的應(yīng)用 　　1). 賓語(yǔ)從句在表示提議、要求、命令、意志等動(dòng)詞后，其謂語(yǔ)用should+動(dòng)詞原形或只用動(dòng)詞原形的虛擬語(yǔ)氣，作為suggest，request，demand，urge，propose，prefer，advise，insist，require，order，command，maintain，ask，object, arrange, desire等動(dòng)詞的賓語(yǔ)。 　　如： 　　The doctor suggested that he not go there．醫(yī)生建議他不要去那里。 　　He suggested that we should leave early. 他建議我們?cè)琰c(diǎn)動(dòng)身。 　　The judge ordered that the prisoner should be remanded. 法官命令被告還押。 　　2). wish的賓語(yǔ)的從句，表示愿望，常省去連詞that。 　　☆ 從句的謂語(yǔ)動(dòng)詞可用過(guò)去式，表示現(xiàn)在的愿望（與現(xiàn)在事實(shí)相反），雖實(shí)現(xiàn)的可能性不大，但仍有實(shí)現(xiàn)的可能。 I wish it were true．我但愿這是真的。 　　 　　☆ 從句的謂語(yǔ)動(dòng)詞還可用“could（would，might）+動(dòng)詞原形”用來(lái)表示將來(lái)的愿望 I wish you would stay a little longer.我希望你再待一會(huì)兒。 　　 　　☆ 表示無(wú)能為力的過(guò)去愿望（與過(guò)去事實(shí)相反），可用“had +過(guò)去分詞”或“could（would，might）+have+過(guò)去分詞” 　　I wish you had called yesterday．我希望你昨天來(lái)過(guò)電話。 　　We wish you had come to our New Year’s party.我們真希望你來(lái)參加了我們的新年聯(lián)歡會(huì)。 　　3). would rather, would sooner等表示愿望，其賓語(yǔ)從句常用虛擬過(guò)去式。 　　☆ 表示與現(xiàn)在和將來(lái)含義事實(shí)相反的虛擬語(yǔ)氣要用動(dòng)詞的過(guò)去式 　　☆ 用過(guò)去完成式(had + 過(guò)去分詞)表示過(guò)去事實(shí)相反的含義 　　I would rather you came tomorrow.我寧愿你明天來(lái)。 　　I’d sooner she left the heavy end of the work to some one else.我寧愿她把重活留給別人。 　　4). 有些動(dòng)詞，如think, expect, believe,其否定式的賓語(yǔ)從句亦可用should+動(dòng)詞原形。如： 　　I never thought he should refuse.我萬(wàn)沒(méi)有想到他會(huì)拒絕。 　　She did not expect that you should come.她沒(méi)有預(yù)料你會(huì)來(lái)。 3. 虛擬語(yǔ)氣在表語(yǔ)從句中的應(yīng)用 　　名詞suggestion，proposal，order，advice，demand等作主語(yǔ)，其后的表語(yǔ)從句中的謂語(yǔ)動(dòng)詞一般使用虛擬語(yǔ)氣，用should +動(dòng)詞原形或省略should。 　　My suggestion is that we (should) send a few soldiers to help them.　　 　　我的建議是我們應(yīng)派幾個(gè)戰(zhàn)士去增援他們。 　　My advice is that you (should) treat her well.　　 我的忠告是你應(yīng)該善待她。 　　He makes the demand that she (should) leave the place at once.　　 　　他提出一個(gè)要求，要求她立刻離開(kāi)這個(gè)地方。 　　My suggestion is that we should tell him.我的建議是我們應(yīng)該告訴他。 　　Our only request is that this should be settled as soon as possible. 　　我們唯一的請(qǐng)求就是盡快解決這個(gè)問(wèn)題。 　　注意：虛擬語(yǔ)氣也可以用于同位語(yǔ)從句。 　　如： 　　There was a suggestion that Brown should be dropped from the team.有一項(xiàng)建議是布朗應(yīng)該離隊(duì)。 4. 虛擬語(yǔ)氣在定語(yǔ)從句中的應(yīng)用 　　常用在It is time (that)…句型中，定語(yǔ)從句常用虛擬過(guò)去式 　　It is time the children went to bed.　　 孩子們?cè)缭撋洗菜X(jué)了。（表示催促） 　　Its high time that he began to think how to deal with money.　　 　　他早該開(kāi)始考慮如何與錢打交道。 　　It is time we left.我們?cè)撟吡恕? 　　It is time we went to bed.我們?cè)撊ニX(jué)了。 　　 5. 虛擬式動(dòng)詞原形亦常用在獨(dú)立句中，表愿望 　　Long live the Communist Party of China！中國(guó)共產(chǎn)黨萬(wàn)歲！ 　　God bless you! 上帝保佑你。 　　God damn it! 該死的！ 　　The devil take you! 見(jiàn)鬼去吧！ 　　So be it then. 就那樣吧。 6. 虛擬時(shí)態(tài)與謂語(yǔ)動(dòng)詞時(shí)態(tài)的關(guān)系：從句中的虛擬時(shí)態(tài)往往不受全句謂語(yǔ)時(shí)態(tài)的影響。 　　1) 用于主語(yǔ)從句。試比較： 　　It is important that he should know about this.他必須知道此事。 　　It was important that he should know about this.他必須知道此事。 　　2) 用于賓語(yǔ)從句。試比較： 　　I suggest that we should go tomorrow.我建議我們明天走。 　　I suggested that we should go the next day.我建議我們第二天走。 　　She said, “If I were a boy I would join the army.”她說(shuō)，“我如是男孩，就參軍?！? 　　She said that if she were a boy, she would join the army.她說(shuō)她如是男孩就參軍。 　　但強(qiáng)調(diào)現(xiàn)在時(shí)刻的虛擬式在間接引語(yǔ)中需要遵守時(shí)態(tài)一致的原則。試比較： 　　“If I knew how it worked, I could tell you what to do,” he said. 　　“假如我知道它是如何運(yùn)行的話，我就會(huì)告訴你該怎么辦，”他說(shuō)道。 　　He said that if he had known how it worked he could have told me what to do. 　　他說(shuō)假如他知道它是如何運(yùn)行的話，他就會(huì)告訴我該怎么辦。 　　“If I knew the answer to all your questions Id be a genius,” he said. 　　“我如知道你所有問(wèn)題的答案，我就是天才了?！彼f(shuō)道。 　　He said that if he knew the answer to all my questions, he’d be a genius. 　　他說(shuō)他如知道我所有問(wèn)題的答案，他就是天才了。 　　但如果全句謂語(yǔ)是虛擬語(yǔ)氣，其后從句的時(shí)態(tài)則多受其影響，現(xiàn)在時(shí)態(tài)應(yīng)隨之而變?yōu)檫^(guò)去時(shí)態(tài)。 　　如： 　　I would think he was wrong.我看他是錯(cuò)了。(須用was,試比較：I think he is wrong) 　　It would seem that she was right. 她似乎是對(duì)的。(須用was,試比較：It seems that she is right) 專項(xiàng)練習(xí)：　　 　　1．His doctor suggested that he ______ a short leave of absence． 　　A．will take　　 B．would take　　 C．take　　 D．took 　　2．The job would require that ______ at 7 oclock every morning． 　　A．he will be at the factory　　 B．he be at the factory 　　C．he was at the factory　　 　　D．he has been at the factory 　　3．Your advice that she ______ till next week is reasonable． 　　A．will wait　　 B．is going to wait　　 C．waits　 D．wait 　　4．The housemaster was strict．He requested that we ______ television on week nights． 　　A．not watch　　　　　　　　　　　　　　 B．must not to watch 　　C．not be watching　　　　　　　　 　　　D．have not watched 　　5．It is necessary that a worker ______ his work on time． 　　A．a(chǎn)ccomplishes　　　　　　　　　　 B．can accomplish 　　C．a(chǎn)ccomplish　　　　　　　　　　　 D．has accomplished 　　6．It is important that he ______ his decision before Friday． 　　A．will make　　 B．makes　　 C．make　　 D．must make 　　7．You look so tired.
