略1.句型提示法虛擬語(yǔ)氣可以用在狀語(yǔ)從句、名詞性從句、定語(yǔ)從句中，在不同的從句中，虛擬語(yǔ)氣用不同的動(dòng)詞形式來(lái)體現(xiàn)，如：if非真實(shí)條件句(分三種情形)，wish后的賓語(yǔ)從句，It is time that.的定語(yǔ)從句等。所以，掌握了各類(lèi)從句中虛擬語(yǔ)氣的動(dòng)詞形式，就基本上掌握了虛擬語(yǔ)氣的用法。If we _ the other road，we might have arrived here in time for the meeting.A.take B.had takenC.took D.have taken答案B句意：如果我們走另一條路的話，我們或許能夠及時(shí)到達(dá)這里參加這次會(huì)議了。根據(jù)主句的謂語(yǔ)動(dòng)詞might have arrived可以推出，本句是與過(guò)去事實(shí)相反的虛擬語(yǔ)氣，所以if條件句中應(yīng)該用過(guò)去完成時(shí)。2.特定詞匯暗示法英語(yǔ)中某些短語(yǔ)如：If it were not for/had not been for, but for., if only., without等，往往要采用虛擬語(yǔ)氣，它們對(duì)于解答試題有很大的幫助，掌握了這些要點(diǎn)知識(shí)，做起題來(lái)也就很容易了。Thank you for all your hard work last week.I dont think we _ it without you.A.can manage B.could have managedC.could manage D.can have managed答案B根據(jù)without you可知，本句是對(duì)過(guò)去事情的虛擬推測(cè)，故用could have過(guò)去分詞。針 對(duì) 訓(xùn) 練1.Had the governments and

done形式。故選D。2.George _ too far.His coffee is still warm.(2016浙江卷)A.must have gone B.might have goneC.cant have gone D.neednt have gone答案C句意：?jiǎn)讨尾豢赡茏哌h(yuǎn)。他的咖啡還是熱的。cant have
