15、條件句的謂語(yǔ)就截然不同。如：If it rains tomorrow，our picnic will be put off.如果明天下雨，我們的郊游就推遲。(陳述語(yǔ)氣，說(shuō)話人認(rèn)為下雨的可能性很大。)If it rained tomorrow，our picnic would be put off.萬(wàn)一明天下雨，我們的郊游就推遲。(虛擬語(yǔ)氣，說(shuō)話人認(rèn)為下雨的可能性較小。)2虛擬語(yǔ)氣在句子中的應(yīng)用(1)虛擬語(yǔ)氣在非真實(shí)性條件句中的應(yīng)用虛擬條件句主句例句與現(xiàn)在事實(shí)相反的假設(shè)If主語(yǔ)動(dòng)詞的過(guò)去式(be動(dòng)詞用were)主語(yǔ)should(would，could，might)動(dòng)詞原形If I had tim

18、had，should，有時(shí)可把if省略掉，把were，had，should放在主語(yǔ)前，構(gòu)成倒裝，意思不變。如：Were I twenty now，I would join the army.If I were twenty now，I would join the army.如果我今年二十歲，我就參軍。Had we made a great effort, we might have succeeded.If we had made a great effort，we might have succeeded.如果我們做了很大的努力的話，我們可能就獲得成功了。Should Mr.White c
19、all，what would you say?If Mr.White should call，what would you say?如果懷特先生來(lái)電話你怎么說(shuō)？(2)有時(shí)候，條件從句表示的動(dòng)作和主句表示的動(dòng)作發(fā)生的時(shí)間是不一致的，我們稱(chēng)之為“錯(cuò)綜時(shí)間條件句”。這時(shí)，動(dòng)詞的形式要根據(jù)其所表示的時(shí)間做出相應(yīng)的調(diào)整。如：If the doctor hadnt tried their best to save you，you wouldnt be standing here now.如果不是醫(yī)生全力以赴把你救活的話，你現(xiàn)在就不會(huì)站到這里。(3)有時(shí)假設(shè)的情況并不以條件從句表示而是通過(guò)一個(gè)介詞短語(yǔ)來(lái)表示
20、，或是通過(guò)上下文等其他手段來(lái)表現(xiàn)出來(lái)。We couldnt have finished the work ahead of time without your help.(if we hadnt got your help)沒(méi)有你們的幫助，我們不可能提前完成任務(wù)。What would you do with a million dollars？(if you had a million dollars)如果你有一百萬(wàn)美元，你打算怎么花？But for the rain(If it hadnt been for the rain)，we would have finished the work.

22、 have known nothing about it.他打來(lái)電話通知我你的生日，否則我對(duì)此一無(wú)所知。Everything taken into consideration，they would have raised their output quickly.如果當(dāng)初考慮全面，產(chǎn)量會(huì)迅速上升。3虛擬語(yǔ)氣在其他從句中及一些固定句式中的用法。(1)在動(dòng)詞wish后的賓語(yǔ)從句中，動(dòng)詞用過(guò)去時(shí)態(tài)(與現(xiàn)在事實(shí)相反)、過(guò)去完成時(shí)態(tài)(與過(guò)去事實(shí)相反)、過(guò)去將來(lái)時(shí)態(tài)，用would動(dòng)詞原形(與將來(lái)事實(shí)相反)。如：I wish we could go to the seaside today.我們今天能去海濱
23、就好了。I wish he would try again.我希望他還能再試一次。We wish we had paid more attention to our pronunciation.我們對(duì)發(fā)音注意得更多一些就好了。注意：would(should)like(love)后接不定式的完成式所表達(dá)的意思與wish后賓語(yǔ)從句用過(guò)去完成時(shí)態(tài)這種形式相同，意思是“希望過(guò)去做了某事”。如：Id like to have seen his face when he opened the letter.(I wish I had seen his face.)我真希望能看一看他打開(kāi)信時(shí)的表情。這種結(jié)構(gòu)

25、!我要是聽(tīng)了你的勸告就好了！(3)在suggest(建議)，propose(提議)，demand(要求)，request(請(qǐng)求)，desire(要求)，require(請(qǐng)求)，order(命令)，command(命令)，insist(堅(jiān)持)等動(dòng)詞后的賓語(yǔ)從句中的謂語(yǔ)動(dòng)詞用should動(dòng)詞原形(should可以省略)。如：The officer ordered that the army(should)advance 100 miles.軍官命令部隊(duì)前進(jìn)100英里。The chief commanded that the prisoners(should)not be shot.首領(lǐng)下令不準(zhǔn)槍殺
26、俘虜。注意：當(dāng)suggest意思為“暗示、表明”，insist意思為“堅(jiān)持認(rèn)為、說(shuō)”，且后面的從句中的動(dòng)作已經(jīng)發(fā)生時(shí)，他們后面的從句都不用虛擬語(yǔ)氣。如：Her expression suggested that she was angry.她的表情表明她生氣了。The girl insisted that she gave me the money the other day.那女孩堅(jiān)持說(shuō)她幾天前把錢(qián)給我了。(4)在It is suggested；It is requested；It is ordered；It is necessary/natural/important；It has bee
