I could have done it better if I had been more careful. 與將來(lái)事 實(shí)相反 過(guò)去式/ were to do/ should do would/should/could/might do If I were to do it，I would do it in a different way. I would certainly go if I had time. 1.在具體運(yùn)用中，條件從句中有時(shí)可省略if而采用倒裝結(jié)構(gòu)。如： Had it not been for your help，we wouldnt have achieved so much. 2．介詞without/but for、連詞but、副詞otherwise常用來(lái)表示某種假設(shè)條件。如： I wouldnt have made such rapid progress without your help. 3．有時(shí)候從句動(dòng)作和主句動(dòng)作發(fā)生的時(shí)間不一致，這時(shí)謂語(yǔ)動(dòng)詞的形式要根據(jù)各自的時(shí)間來(lái)調(diào)整。如： If the weather had been more favourable，the crops would be growing still better. 【典例分析】 (xx湖南高考，29)Sorry，I am too busy now.If I ______ time，I would certainly go for an outing with you. A．have had B．had had C．have D．had 答案為D項(xiàng)。句意：很抱歉，我現(xiàn)在很忙。要是我有時(shí)間，一定會(huì)與你去遠(yuǎn)足的。根據(jù)句意可知，此處表示與現(xiàn)在事實(shí)相反的虛擬語(yǔ)氣，條件句中謂語(yǔ)動(dòng)詞要用過(guò)去時(shí)。 (xx浙江高考，19)Had they known what was ing next，they ______ second thoughts. A．may have B．could have C．must have had D．might have had 答案為D項(xiàng)。句意：如果他們知道接下來(lái)會(huì)發(fā)生什么，他們可能就會(huì)再三考慮了。該題前半句為省略了if而構(gòu)成倒裝的虛擬條件句，與過(guò)去事實(shí)相反，所以主句應(yīng)用would / should / could / might have done的形式。 (xx安徽高考，31)Grace doesnt want to move to New York because she thinks if she ______ there，she wouldnt be able to see her parents very often. A．lives B．would live C．has lived D．were to live 答案為D項(xiàng)。句意：格雷斯不想搬到紐約去，因?yàn)樗J(rèn)為如果她住在那兒的話，就不能經(jīng)常見(jiàn)到父母了。由句意可知，這是對(duì)將來(lái)事情的虛擬，所以條件句中可以用過(guò)去式 / were to do或should do的形式。 考點(diǎn)十：虛擬語(yǔ)氣在名詞從句中的用法 1．在wish后面的賓語(yǔ)從句中用虛擬語(yǔ)氣，從句謂語(yǔ)向前推一個(gè)時(shí)態(tài)。如： I failed in the exam.I really wish I had known the answers. 在it is wished that引導(dǎo)的主語(yǔ)從句以及名詞wish后面的表語(yǔ)從句、同位語(yǔ)從句中也要用虛擬語(yǔ)氣，謂語(yǔ)的形式同wish后面賓語(yǔ)從句的形式。如： It is wished that man could fly freely in the sky. 注意：wish的時(shí)態(tài)和后面從句的時(shí)態(tài)無(wú)關(guān)。 2．在insist(堅(jiān)決要求)/suggest(建議)/remend/propose/order/demand/require/request等后的賓語(yǔ)從句中要用虛擬語(yǔ)氣，從句謂語(yǔ)用(should) do的形式。如： He suggested that we (should) start at once. 在it is suggested/proposed that引導(dǎo)的主語(yǔ)從句以及名詞insistence/suggestion/ proposal/order/demand等后面的表語(yǔ)從句、同位語(yǔ)從句中也要用虛擬語(yǔ)氣，謂語(yǔ)的形式同這些名詞相應(yīng)的動(dòng)詞后面賓語(yǔ)從句的形式。如： Their proposal is that their output (should) be increased by 20%. 3．在it is necessary/important/possible/strange/no wonder/a pity/a shame等后面的主語(yǔ)從句中要用虛擬語(yǔ)氣，謂語(yǔ)用(should) do 的形式。如： It is necessary that he (should) be sent there at once. 4．在it is time that后面的從句中用虛擬語(yǔ)氣，謂語(yǔ)用過(guò)去式或should do的形式，should不可省略。 It is time that we went / should go to bed. 5．在as if / as though后面的從句中也常用虛擬語(yǔ)氣。 She always talks to me as if she were my sister. 【典例分析】 (xx遼寧高考，33)Jack is a great talker.Its high time that he ______ something instead of just talking. A．will do B．has done C．do D．did 答案為D項(xiàng)。句意：杰克是個(gè)空談家。到了他做點(diǎn)事而不是夸夸其談的時(shí)候了。it is high time后面的從句中要用虛擬語(yǔ)氣，其謂語(yǔ)動(dòng)詞多用一般過(guò)去時(shí)，或should do的形式，should 不能省略，故只有D項(xiàng)正確。 (xx北京高考，35)Dont handle the vase as if it ______ made of steel. A．is B．were C．has been D．had been 答案為B項(xiàng)。在as if 引導(dǎo)的條件句中應(yīng)用虛擬語(yǔ)氣，表示與現(xiàn)在事實(shí)相反時(shí)用一般過(guò)去時(shí)，而且不論第幾人稱，be動(dòng)詞都用were。句意：不要對(duì)待那些花瓶好像他們是由鋼制成似的。 誤區(qū)警示 1．情態(tài)動(dòng)詞基本用法的易錯(cuò)點(diǎn) (xx重慶高考，25)— ______ you interrupt now？Cant you see Im on the phone? — Sorry Sir，but its urgent. A．Can B．Should C．Must D．Would 【錯(cuò)混透析】C　must可表示與說(shuō)話者主觀愿望相反或表示一種不耐煩情緒，意為“偏要，偏偏”，根據(jù)語(yǔ)境可知說(shuō)話者正忙著打電話，不滿意對(duì)方的打攪，所以選C項(xiàng)。句意：——你現(xiàn)在偏要打攪我嗎？難道你沒(méi)看見(jiàn)我正在打電話嗎？——對(duì)不起，先生。但是有急事。can表示“能夠，可能”；should表示“應(yīng)該”；would表示“將要，愿意”。均不合題意。 【解題指導(dǎo)】 對(duì)于考查情態(tài)動(dòng)詞基本用法的題目，首先要掌握各選項(xiàng)的基本意義和用法，其次要注意結(jié)合情景特征，體會(huì)說(shuō)話者的語(yǔ)氣和態(tài)度，不要放過(guò)任何細(xì)節(jié)，利用有效信息，作出最佳選擇。 2．情態(tài)動(dòng)詞表示推測(cè)的易錯(cuò)點(diǎn) (xx江西高考，23)It ______ be the postman at the door.Its only six oclock. A．mustnt B．cant C．wont D．neednt 【錯(cuò)混透析】 B　mustnt“不許，不可以”，表示禁止；cant“不可能”；wont“將不會(huì)”；neednt“不需要”。后一句表明現(xiàn)在時(shí)間僅僅是六點(diǎn)，only一詞肯定語(yǔ)氣強(qiáng)烈，所以選B項(xiàng)表示否定的推測(cè)，這么早絕不可能是郵遞員。 【解題指導(dǎo)】 遇到考查情態(tài)動(dòng)詞表示推測(cè)的題目，可通過(guò)三步作出判斷。首先看是肯定句、否定句還是疑問(wèn)句?？隙ň渲幸话阌胢ust/may/might；否定句和疑問(wèn)句中一般用can/could。然后看是對(duì)什么時(shí)間的推測(cè)：表示對(duì)現(xiàn)在的推測(cè)用“情態(tài)動(dòng)詞＋do”，表示對(duì)過(guò)去的推測(cè)用“情態(tài)動(dòng)詞＋have done”。最后看句子語(yǔ)氣的肯定程度，must(十分肯定)＞may(不太肯定)＞could/might(可能性較小)。 3．“情態(tài)動(dòng)詞＋have done”結(jié)構(gòu)的易錯(cuò)點(diǎn) (xx北京高考，33)We ______ the difficulty together，but why didnt you tell me? A．should face B．might face C．could have faced D．must have faced 【錯(cuò)混透析】C　句意：我們本可以一起面對(duì)困難的，但是你為什么不告訴我？could have done意為“(過(guò)去)本可以做某事(但實(shí)際上沒(méi)做)”；should do意為“(現(xiàn)在)應(yīng)該做”；might do意為“可能做某事”，must have done意為“(過(guò)去)一定做過(guò)某事”。根據(jù)句意判斷應(yīng)選C項(xiàng)。由于忽視后面句子的時(shí)間，該題易誤選A項(xiàng)。 【解題指導(dǎo)】 “情態(tài)動(dòng)詞＋have done”結(jié)構(gòu)是高考中經(jīng)常考查的內(nèi)容。要分清不同的情態(tài)動(dòng)詞所構(gòu)成的結(jié)構(gòu)表達(dá)的不同含義。 (1)must have done表示“過(guò)去一定做過(guò)某事”。 (2)may/might have done表示“過(guò)去也許做過(guò)某事”。 (3)should/ought to have done表示“過(guò)去本應(yīng)該做某事(而實(shí)際上未做)”。 (4)could have done表示“(過(guò)去)本能夠做某事(而實(shí)際上未做)”。 (5)need not have done表示“(過(guò)去)本不必、無(wú)需做某事(而已做)”。 4．隱含虛擬條件中虛擬語(yǔ)氣的易錯(cuò)點(diǎn) (xx陜西高考，22)I ______ through that bitter period without your generous help. A．couldnt have gone B．didnt go C．wouldnt go D．hadnt gone 【錯(cuò)混透析】 A　句意：如果沒(méi)有你們的慷慨相助，我不可能度過(guò)那段艱辛的歲月。without...表示該句應(yīng)用與過(guò)去事實(shí)相反的虛擬語(yǔ)氣，應(yīng)用would/could/should/might＋have done，故選A項(xiàng)。 【解題指導(dǎo)】虛擬語(yǔ)氣的題目有時(shí)并不出現(xiàn)if條件句，而是通過(guò)without/but for/or/otherwise等暗示虛擬的語(yǔ)境。 5．固定句型中虛擬語(yǔ)氣的易錯(cuò)點(diǎn) (xx北京高考，28)—Where are the children？The dinners going to be pletely ruined. —I wish they ______ always late. A．werent B．hadnt been C．wouldnt be D．wouldnt have been 【錯(cuò)混透析】 A　wish后面的賓語(yǔ)從句中，與現(xiàn)在事實(shí)相反時(shí)，謂語(yǔ)用一般過(guò)去時(shí)；與過(guò)去事實(shí)相反時(shí)，謂語(yǔ)用過(guò)去完成時(shí)。題干中出現(xiàn)always，從句應(yīng)使用一般過(guò)去時(shí)。 【解題指導(dǎo)】 要想做好固定句型中虛擬語(yǔ)氣的題目，既要熟記這些句型，又要記住不同的句型中虛擬語(yǔ)氣的表達(dá)方式，即謂語(yǔ)用什么形式。 1．Reading without thinking is like eating without digesting.Never accept whatever is written in a book easily，for even experts ______ make mistakes.
