虛擬語(yǔ)氣(1) 動(dòng)詞的語(yǔ)氣表示說(shuō)話人的態(tài)度和看法，可分為陳述語(yǔ)氣、祈使語(yǔ)氣和虛擬語(yǔ)氣。陳述語(yǔ)氣用來(lái)陳述講話人認(rèn)為是事實(shí)的事情，有肯定、否定、疑問和感嘆等形式。祈使語(yǔ)氣用來(lái)說(shuō)明說(shuō)話人的請(qǐng)求、命令等。虛擬語(yǔ)氣表示說(shuō)話人的愿望、假設(shè)或建議，而不表示客觀存在的事實(shí)。虛擬語(yǔ)氣通過謂語(yǔ)動(dòng)詞的特殊形式來(lái)表示。,如果假設(shè)的情況發(fā)生的可能性不大，則用虛擬條件句。虛擬條件句分為三種，見下表：,If I had time，I would attend the meeting.如果我有時(shí)間，我就參加會(huì)議了。(與現(xiàn)在事實(shí)相反) If I were you, I should seize the chance to go abroad. 如果我是你，我會(huì)抓住這個(gè)出國(guó)的機(jī)會(huì)。(與現(xiàn)在事實(shí)相反) If you had taken my advice, you would not have failed in the exams.如果你采納了我的建議，你就不會(huì)通不過考試了。(與過去事實(shí)相反) If you came tomorrow, we would have the meeting. 如果你明天來(lái)，我們將召開會(huì)議。(與將來(lái)事實(shí)相反),If it were to rain, we should get wet.要是下雨的話，我們就會(huì)淋濕了。(與將來(lái)事實(shí)相反) If he should not come tomorrow, we should put off the meeting till next Monday.如果明天他不來(lái)，我們就要把會(huì)議推到下周一。(與將來(lái)事實(shí)相反),【單項(xiàng)填空】 ①Sorry, I didn’t finish my work. If I________ enough time, I________it. A．had; would finish B．have; could have finished C．had had; would have finished D．have had; have finished ②He is not native; if he were; we ________this discussion over his identity. A．would not be having B．a(chǎn)re not having C．had not had D．will not have,答案 ①C [由前句可知后句應(yīng)使用虛擬語(yǔ)氣，表示與過去情況相反。if引導(dǎo)的非真實(shí)條件句中的謂語(yǔ)動(dòng)詞形式為：had＋動(dòng)詞-ed形式；主句謂語(yǔ)動(dòng)詞的形式為：would/should/might/could have＋動(dòng)詞-ed形式。] ②A [考查虛擬語(yǔ)氣的用法。句意：他不是本國(guó)人，如果他是的話，我們就不會(huì)在討論他的身份問題了。根據(jù)were可知，此處為與現(xiàn)在事實(shí)相反的虛擬語(yǔ)氣，而只有A項(xiàng)是虛擬語(yǔ)氣主句的結(jié)構(gòu)。],【單項(xiàng)填空】 ________strict with me when I was young，I could not be such a successful person now. A. If you are not B．If you were not C．Were you not D．If you had not been 答案 D [考查錯(cuò)綜虛擬語(yǔ)氣。句意：如果在我年幼時(shí)你沒有對(duì)我嚴(yán)格要求的話，我現(xiàn)在就不可能是這么成功的一個(gè)人。根據(jù)句意可知，此題中主句說(shuō)的是與現(xiàn)在事實(shí)相反的情況，而從句說(shuō)的是與過去事實(shí)相反的情況，所以從句要用過去完成時(shí)，故選D，如果采用省略句，其結(jié)構(gòu)應(yīng)該是had you not been。],【單項(xiàng)填空】 ①________ today, he would get there by Friday. But he won’t set off when it is raining. A．Would he leave B．Was he leaving C．Were he to leave D．If he leaves ②________ listened to the doctor, you ________ all right now. A．If you; are B．If you; were C．You had; would be D．Had you; would be,答案 ①C [由語(yǔ)境可知非真實(shí)條件從句表示將來(lái)不可能實(shí)現(xiàn)的事情，故從句謂語(yǔ)動(dòng)詞的形式為：過去式(be用were)/should ＋動(dòng)詞原形/were to＋動(dòng)詞原形，如果省略 if，要將從句中的were，should，had等提到句首。] ②D [根據(jù)主句中的時(shí)間狀語(yǔ)now，可知表示與現(xiàn)在情況相反，故主句中謂語(yǔ)動(dòng)詞的形式為would＋動(dòng)詞原形。依據(jù)語(yǔ)境可知條件句表示與過去情況相反，故條件句中謂語(yǔ)動(dòng)詞的形式為had＋動(dòng)詞的-ed形式，省略if時(shí)，要將had提到句首。],(3)通過上下文的含義，句中往往有but，otherwise等。 I was very busy yesterday, otherwise I would have helped you.我昨天很忙，不然的話，我會(huì)幫助你的。 She would have said no. But that she was afraid. 要不是她害怕的話，她就會(huì)說(shuō)“不”了。 If only I had more money, I could buy the apartment. 要是我有更多的錢，我就會(huì)買這套公寓了。 But for your advice, I could not have done it so successfully. 如果不是聽了你的建議，我就不會(huì)做得如此成功。 The change could not have taken place without the open-door policy.沒有開放的政策，就不會(huì)有如此大的變化。,【單項(xiàng)填空】 ①Without water in the world, everything ________. A．will die B．would die C．would have died D．has died ②Thanks a lot. We ________the work on time without your help. A．hadn’t finished B．didn’t finish C．couldn’t have finished D．couldn’t finish,答案 ①B [without短語(yǔ)表示非真實(shí)條件，故句子使用虛擬語(yǔ)氣。因其表示與現(xiàn)在事實(shí)相反，謂語(yǔ)動(dòng)詞的形式應(yīng)為：would＋動(dòng)詞原形。] ②C [根據(jù)Thanks a lot.可知without your help表示非真實(shí)條件，故后句中應(yīng)使用虛擬語(yǔ)氣，由語(yǔ)境可知句子表示與過去情況相反，故謂語(yǔ)動(dòng)詞的形式應(yīng)為：would/should/might/could have＋動(dòng)詞-ed形式。],議論文 【寫作任務(wù)】 假如你是本地報(bào)社的一名記者，要對(duì)昨天新華中學(xué)的學(xué)生就“是否允許醫(yī)學(xué)克隆存在？”展開的辯論進(jìn)行報(bào)道，下表是雙方理由和辯論結(jié)果，請(qǐng)據(jù)此寫一篇新聞稿。,【寫作內(nèi)容】,3．根據(jù)題目要求對(duì)辯論情況進(jìn)行客觀報(bào)道，準(zhǔn)確把握要點(diǎn)。準(zhǔn)確運(yùn)用高級(jí)詞匯并注意新聞?lì)愺w裁的語(yǔ)言特點(diǎn)。適當(dāng)運(yùn)用復(fù)雜結(jié)構(gòu)以提高文章的表述層次。注意篇章的整體處理和語(yǔ)言的連貫，并力求條理清晰、層次分明。,第二步：提煉要點(diǎn) 1．medical cloning 2．support the motion 3．serious illnesses 4．procedures would be safe 5．convincing 6．to oppose medical cloning 7．potential lives 8．a(chǎn) lively discussion,第三步：擴(kuò)點(diǎn)成句 1．The arguments for medical cloning were very strongly put by the team supporting the motion. 2．They argued that people who were losing their ability to move or think because of serious illnesses could be helped by medical cloning. 3．They explained that the procedures would be safe, quick and with no problems for the patients. 4．Their arguments were very convincing. 5．The arguments put by the team opposing medical cloning were less strong.
