虛擬語氣Ⅱ教學(xué)案 于亞東 　　虛擬語氣除主要用于條件句（也就是狀語從句）外，還可用于主語從句、賓語從句、表語從句、定語從句等。 1. 虛擬語氣在主語從句中的應(yīng)用 　　“常用在It is (was)+形容詞 / 過去分詞+that引導(dǎo)的主語從句”的句型中的主語從句要用虛擬語氣。主語從句的謂語用should+動詞原形(或should+have+過去分詞)或只用動詞原形(尤其是美國英語)。should在此是助動詞，本身并無實義，這種主語從句中的should有時有感情色彩。 　　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. 　　 　　☆ 用于本句型中的過去分詞就是表示提議、要求、命令等動詞的過去分詞，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．有人建議推遲會議。 　　It is settled that you leave us, then? 　　 　　注意：這種句型中的主語從句也可用陳述語氣，如：It was important that he made an explicit statement on this score last week. 他上個星期對于這一方面做了明確的說明，這是很重要的。 2. 虛擬語氣在賓語從句中的應(yīng)用 　　1). 賓語從句在表示提議、要求、命令、意志等動詞后，其謂語用should+動詞原形或只用動詞原形的虛擬語氣，作為suggest，request，demand，urge，propose，prefer，advise，insist，require，order，command，maintain，ask，object, arrange, desire等動詞的賓語。 　　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. 他建議我們早點動身。 　　The judge ordered that the prisoner should be remanded. 法官命令被告還押。 　　2). wish的賓語的從句，表示愿望，常省去連詞that。 　　☆ 從句的謂語動詞可用過去式，表示現(xiàn)在的愿望（與現(xiàn)在事實相反），雖實現(xiàn)的可能性不大，但仍有實現(xiàn)的可能。 I wish it were true．我但愿這是真的。 　　 　　☆ 從句的謂語動詞還可用“could（would，might）+動詞原形”用來表示將來的愿望 I wish you would stay a little longer.我希望你再待一會兒。 　　 　　☆ 表示無能為力的過去愿望（與過去事實相反），可用“had +過去分詞”或“could（would，might）+have+過去分詞” 　　I wish you had called yesterday．我希望你昨天來過電話。 　　We wish you had come to our New Year’s party.我們真希望你來參加了我們的新年聯(lián)歡會。 　　3). would rather, would sooner等表示愿望，其賓語從句常用虛擬過去式。 　　☆ 表示與現(xiàn)在和將來含義事實相反的虛擬語氣要用動詞的過去式 　　☆ 用過去完成式(had + 過去分詞)表示過去事實相反的含義 　　I would rather you came tomorrow.我寧愿你明天來。 　　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). 有些動詞，如think, expect, believe,其否定式的賓語從句亦可用should+動詞原形。如： 　　I never thought he should refuse.我萬沒有想到他會拒絕。 　　She did not expect that you should come.她沒有預(yù)料你會來。 3. 虛擬語氣在表語從句中的應(yīng)用 　　名詞suggestion，proposal，order，advice，demand等作主語，其后的表語從句中的謂語動詞一般使用虛擬語氣，用should +動詞原形或省略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.　　 　　他提出一個要求，要求她立刻離開這個地方。 　　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. 　　我們唯一的請求就是盡快解決這個問題。 　　注意：虛擬語氣也可以用于同位語從句。 　　如： 　　There was a suggestion that Brown should be dropped from the team.有一項建議是布朗應(yīng)該離隊。 4. 虛擬語氣在定語從句中的應(yīng)用 　　常用在It is time (that)…句型中，定語從句常用虛擬過去式 　　It is time the children went to bed.　　 孩子們早該上床睡覺了。（表示催促） 　　Its high time that he began to think how to deal with money.　　 　　他早該開始考慮如何與錢打交道。 　　It is time we left.我們該走了。 　　It is time we went to bed.我們該去睡覺了。 　　 5. 虛擬式動詞原形亦常用在獨立句中，表愿望 　　Long live the Communist Party of China！中國共產(chǎn)黨萬歲！ 　　God bless you! 上帝保佑你。 　　God damn it! 該死的！ 　　The devil take you! 見鬼去吧！ 　　So be it then. 就那樣吧。 6. 虛擬時態(tài)與謂語動詞時態(tài)的關(guān)系：從句中的虛擬時態(tài)往往不受全句謂語時態(tài)的影響。 　　1) 用于主語從句。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，“我如是男孩，就參軍。” 　　She said that if she were a boy, she would join the army.她說她如是男孩就參軍。 　　但強調(diào)現(xiàn)在時刻的虛擬式在間接引語中需要遵守時態(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行的話，我就會告訴你該怎么辦，”他說道。 　　He said that if he had known how it worked he could have told me what to do. 　　他說假如他知道它是如何運行的話，他就會告訴我該怎么辦。 　　“If I knew the answer to all your questions Id be a genius,” he said. 　　“我如知道你所有問題的答案，我就是天才了。”他說道。 　　He said that if he knew the answer to all my questions, he’d be a genius. 　　他說他如知道我所有問題的答案，他就是天才了。 　　但如果全句謂語是虛擬語氣，其后從句的時態(tài)則多受其影響，現(xiàn)在時態(tài)應(yīng)隨之而變?yōu)檫^去時態(tài)。 　　如： 　　I would think he was wrong.我看他是錯了。(須用was,試比較：I think he is wrong) 　　It would seem that she was right. 她似乎是對的。(須用was,試比較：It seems that she is right) 專項練習(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.
