情態(tài)動(dòng)詞是每年高考的熱點(diǎn)也是難點(diǎn)，每年單項(xiàng)填空題必考一題。考點(diǎn)集中在：情態(tài)動(dòng)詞表示推測(cè)的基本用法及區(qū)別;情態(tài)動(dòng)詞否定式的用法辨析：情態(tài)動(dòng)詞+have done的用法區(qū)別等。以下是學(xué)習(xí)啦小編為大家編輯的英語學(xué)習(xí)方法文章，僅供考生參考，歡迎大家閱讀!

　　高考英語復(fù)習(xí)知識(shí)點(diǎn)：情態(tài)動(dòng)詞和虛擬語氣

　　虛擬語氣在高考命題中不是重點(diǎn)，但是難點(diǎn)。考點(diǎn)常集中在含蓄條件句以及主語、賓語從句等特定句型中虛擬語氣的使用上，因此考生應(yīng)熟練掌握含蓄條件句中主從句的時(shí)態(tài)要求以及一些典型句型中虛擬語氣的具體形式。

　　虛擬語氣考點(diǎn)透析

　　考點(diǎn)一、虛擬語氣的基本用法

　　1.與現(xiàn)在事實(shí)相反的虛擬語氣，基本結(jié)構(gòu)為：主語+動(dòng)詞的一般過去時(shí)(be動(dòng)詞用were)+其他成分+if+should/would/could...+動(dòng)詞原形+其他成分。例如：

　?、買f it were not for the fact that she ______ sing，I would invite her to the party.

　　A.couldnt B.shouldnt C.cant D.might not

　　解析 句意為：如果不是因?yàn)樗粫?huì)唱歌的事實(shí)，我會(huì)邀請(qǐng)她來參加那次聚會(huì)的。that從句為同位語從句，描述的是事實(shí)，用陳述語氣。正確答案為C。

　　2.與過去事實(shí)相反的虛擬語氣，基本結(jié)構(gòu)為：主語+動(dòng)詞的過去完成時(shí)+其他成分+if+should/would/could...+have done+其他成分。例如：

　　If the weather had been better，we could have had a picnic.But it ______ all day.

　　A.rained B.rains C.has rained D.is raining

　　解析 句意為：如果天氣好的話，我們是能夠去野餐的，但是下了一天的雨。句子前半部分陳述的是與過去事實(shí)相反的事情，所以用了虛擬語氣。下了一天的雨是事實(shí)，所以用陳述語氣。因?yàn)槭前l(fā)生在過去的事實(shí)，所以正確答案為A。

　　3.與將來事實(shí)相反的虛擬語氣，基本結(jié)構(gòu)為：主語+動(dòng)詞的一般過去時(shí)/should do/were to do+其他成分+if+should/would/could...+動(dòng)詞原形+其他成分。例如：

　　If I ______ plan to do anything I want to，Id like to go to Tibet and travel through as much of it as possible.

　　A.would B.could C.had to D.ought to

　　解析 句意為：如果我能夠計(jì)劃做我想做的事情，我想去西藏并且盡可能多玩一些地方。句子描述的是與將來事實(shí)相反的事情，所以正確答案為B。

　　考點(diǎn)二、含蓄虛擬條件句

　　這樣的虛擬句不含有if從句，而是以but for/without/or/otherwise等引導(dǎo)的句子代替if從句，主句的謂語動(dòng)詞的形式與前面虛擬語氣的基本用法相同。例如：

　　Thank you for all your hard work last week.I dont think we ______ it without you.

　　A.can manage B.could have managed

　　C.could managed D.can have managed

　　解析 由語境可知這里要表達(dá)的意思是：如果沒有你們辛勤的工作，我們不可能處理好這件事。很顯然，這是對(duì)過去發(fā)生的事實(shí)的虛擬，所以要用could have done，故應(yīng)選B。

　　考點(diǎn)三、主從句時(shí)間不一致的虛擬條件句

　　在有些虛擬條件句中，主從句時(shí)間不一致，應(yīng)根據(jù)不同情況區(qū)別對(duì)待。例如：

　　Its hard for me to imagine what I would be doing today if I ______ in love，at the age of seven，with the Melinda Cox Library in my hometown.

　　A.wouldnt have fallen B.had not fallen

　　C.should fall D.were to fall

　　解析 句意為：如果不是我在七歲時(shí)愛上家鄉(xiāng)的Melinda Cox圖書館的話，很難想象今天的我會(huì)是什么樣子。主句描述的是與現(xiàn)在事實(shí)相反的事情，從句描述的是與過去事實(shí)相反的事情。正確答案為B。

　　考點(diǎn)四、名詞性從句中的虛擬語氣

　　在含有表示堅(jiān)持、建議、命令、要求等含義的名詞性從句和在it做形式賓語或形式主語的復(fù)合句中，賓語補(bǔ)足語是necessary/strange/essential/natural/a pity/a shame等表示驚奇、惋惜或者理應(yīng)如此等含義時(shí)，從句中的謂語動(dòng)詞需用should+動(dòng)詞原形，其中should可以省略。例如：

　　Dont you think it necessary that he ______ to Miami but to New York?

　　I agree，but the problem is ______ he has refused to.

　　A.will not be sent;that B.not be sent;that

　　C.should not be sent;what D.should not send;what

　　解析 問句句意為：難道你不認(rèn)為必須把他送到邁阿密而不是紐約嗎?句子表示理應(yīng)如此的意思。正確答案為B。

　　情態(tài)動(dòng)詞考點(diǎn)透析

　　考點(diǎn)一、情態(tài)動(dòng)詞基本含義的考查

　　情態(tài)動(dòng)詞的基本含義，一直是高考考查的重要內(nèi)容。例如：

　　1. The fire spread through the hotel very quickly but everyone______get out. A. had to B. would C. was able to D. could

　　解析：考查情態(tài)動(dòng)詞的基本含義。had to：不得不; would：表示意愿或過去常常;could傾向于表示經(jīng)過長期訓(xùn)練而獲得的能力;was able to 表示經(jīng)過努力而能夠做到的事或成功地做了某事。因此，答案是C。

　　分析：高考對(duì)情態(tài)動(dòng)詞基本含義的考查，仍然集中在常用的情態(tài)動(dòng)詞上。對(duì)常用情態(tài)動(dòng)詞的含義，要掌握的既準(zhǔn)確又要全面，特別是shall, should, can, may 四個(gè)常用情態(tài)動(dòng)詞的含義較多，不易理解，復(fù)習(xí)時(shí)應(yīng)當(dāng)引起重視。

　　二、情態(tài)動(dòng)詞表示推測(cè)的考查

　　對(duì)情態(tài)動(dòng)詞表示推測(cè)的用法，是高考考查情態(tài)動(dòng)詞的一個(gè)重要方面。例如：

　　1. Sorry, Im late. I______have turned off the alarm clock and gone back to sleep again .

　　A. might B. should C. can D. will

　　解析：might have done : (過去)可能做過某事;shouldhave done :本應(yīng)該做某事。根據(jù)本句提供的情境Im late 表明說話人可能把鬧鐘關(guān)上了。答案是：A。

　　分析：高考對(duì)表示推測(cè)的情態(tài)動(dòng)詞集中在must, can, could, may, might上，準(zhǔn)確掌握它們使用的場(chǎng)合，是解決問題的關(guān)鍵。Must 用于肯定陳述句，表示肯定推測(cè);can, could用于疑問或否定陳述句，表示可能性推測(cè);may, might用于陳述句，表示可能性推測(cè);用于否定陳述句中，cant (不可能)的語氣比may not(可能不)強(qiáng)。此外，還要注意有對(duì)過去和對(duì)現(xiàn)在兩種情況的推測(cè),對(duì)過去推測(cè)用情態(tài)動(dòng)詞+have done ，對(duì)現(xiàn)在推測(cè)用情態(tài)動(dòng)詞+ 動(dòng)詞原形。

　　三、情態(tài)動(dòng)詞表示虛擬的考查

　　情態(tài)動(dòng)詞+have+過去分詞表示與過去事實(shí)上相反的情況，也是高考單項(xiàng)選擇題涉及到情態(tài)動(dòng)詞的一個(gè)重要方面。

　　1. There was a lot of fun at yesterdays party. You______come, but why didnt you?

　　A. must have B. should

　　C. need have D. ought to have

　　解析：ought to have done 表示本來應(yīng)該做某事而實(shí)際沒做，should do 表示現(xiàn)在應(yīng)該做某事，與題中 at yesterdays party 表示的時(shí)間不一致。所以選D。

　　分析：高考對(duì)情態(tài)動(dòng)詞表示虛擬用法，表示與過去事實(shí)相反的情況。近幾年高考，主要側(cè)重should (not)have done 這一句式上，表示本來不該做卻做了或本來該做卻未做的事，在復(fù)習(xí)時(shí)，還應(yīng)關(guān)注其它幾種虛擬形式，如need (not)have done 表示本來需要做而未做或本來不需要而做的事等等，以做到有備無患。

　　考點(diǎn)四、情態(tài)動(dòng)詞與助動(dòng)詞混合考查

　　1.Tom ,you didnt come to the party last night?

　　I______, but I suddenly remembered I had homework to do .

　　A. had to B. didnt C. was going to D. wouldnt

　　解析：had to:不得不;didnt:沒來;was going to：打算來;wouldnt:不愿來。句意：湯姆，昨晚你沒來參加舞會(huì)嗎?我本打算來，但我突然記起有作業(yè)要做。But是關(guān)鍵詞，所以答案是：C。

　　2.Your phone number again? I______quite catch it .

　　Its 86184867.

　　A. didnt B. couldnt C. dont D. cant

　　解析：記住電話號(hào)碼并非難事，未完全聽清楚電話號(hào)碼并非能力的事，此處只是說沒有完全聽清楚電話號(hào)碼，所以，應(yīng)選A。

　　【答案與解析】

　　1.

　　【解析】選B.Its time you did 為 Its time you thanked Aunt Lucy for her present 之略。按照英語語法，its time 后從句通常要用過去式。

　　2.

　　【解析】選A.雖然前有虛擬條件句, 后有使用了虛擬語氣的賓語，但 I dont know 卻宜用一般現(xiàn)在時(shí)，因?yàn)?I dont know 表述的是現(xiàn)在的真實(shí)情況，句意為我要不是有幸遇到你，我真不知(指現(xiàn)在不知)我會(huì)做出什么蠢事來。

　　3.

　　【解析】選B.Id rather 后接從句時(shí)，從句謂語的時(shí)態(tài)規(guī)律是：用過去式表示現(xiàn)在或?qū)?，用過去完成式表示過去。

　　4.

　　【解析】選A.we cant get there by tomorrow 為客觀事實(shí)，故宜用陳述語氣。

　　5.

　　【解析】選B.第一空填 knew，因?yàn)?I wish 后的賓語從句要用虛擬語氣(即用過去式表示現(xiàn)在的想法);第二空要填lives，即用陳述語氣，因?yàn)?where he lives 是一個(gè)客觀事實(shí)，而不是 I wish 的內(nèi)容。

　　6.

　　【解析】選C.Its time / Its high time / Its about time 等后接從句時(shí)，從句謂語通常用過去式。

　　7.

　　【解析】選 B.此題涉及錯(cuò)綜時(shí)間虛擬條件句，主句與現(xiàn)在事實(shí)相反，條件句與過去事實(shí)相反。句意為：要不是在七歲時(shí)就迷上了 Melinda Cox 圖書館，我真不能想像我如今會(huì)在做什么。

　　8.

　　【解析】8. 選 D.這是otherwise 引出的含蓄虛擬語氣，再根據(jù)前面的 hesitated 可進(jìn)一步知道這是與過去事實(shí)相反的虛擬語氣，由此可推知答案選 D.

　　9.

　　【解析】選 C.if only意為要是就好了，其后的句子謂語要用虛擬語氣，同時(shí)根據(jù) as the doctor instructed 中的過去時(shí)態(tài)可知從句是與過去事實(shí)相反，故選 C.

　　10.

　　【解析】選 A.without 引出的介詞短語為一個(gè)與現(xiàn)在事實(shí)相反的含蓄條件句。

　　【答案】C

　　11.

　　【解析】.根據(jù)上文的語境可知句中的 or 隱含有一個(gè)虛擬的條件，即 or=if I didnt forget where I read the article(要是我沒忘記我在哪兒讀過這篇文章的話但事實(shí)上忘了)。

　　【答案】B

　　12.

　　【解析】關(guān)鍵信息是It looks as if he were drunk 中的虛擬語氣，句子既然用了虛擬語氣，也就是說，他喝醉了不是事實(shí)，只是他的言行好像是醉了，所以此題的最佳答案是D.

　　【答案】 D.

　　13.

　　【解析】 由于空格后的 if 條件狀語從句的謂語用的是虛擬語氣(這是很重要的信息)，所以主句要用 would 而不用 will，即答案應(yīng)選D.

　　【答案】D

　　14.

　　【解析】按照英語習(xí)慣，would rather 后接that 從句時(shí)，從句謂語通常要用虛擬語氣，即用過去式表示現(xiàn)在或?qū)恚?用過去完成時(shí)表示過去。

　　【答案】C

　　15.

　　【解析】insist后的從句謂語有時(shí)用should+動(dòng)詞原形這樣的虛擬語氣，有時(shí)不用，具體要看該謂語動(dòng)詞所表示的含義。一般說來，若該謂語動(dòng)詞所表示的動(dòng)作尚未發(fā)生，或尚未成為事實(shí)，則用虛擬語氣;若該謂語動(dòng)詞所表示的動(dòng)作已經(jīng)發(fā)生，或已經(jīng)成為事實(shí)，則要用陳述語氣。分析上題的句意，可知只有選D最合適。

　　【答案】D

　　16.

　　【解析】是因?yàn)闀r(shí)態(tài)前后有矛盾。由于主句謂語是would not have got，這表明是對(duì)過去事實(shí)作出的假設(shè)，所以從句謂語應(yīng)該是 had given up，而不是像D項(xiàng)那樣用一般過去時(shí)。另外，當(dāng)虛擬條件句中有 had, should, were 等詞時(shí)，通常可以省略 if，并將 had, should, were 提前置于句首。

　　【答案】B

　　17.

　　【解析】Its time you did 為 Its time you thanked Aunt Lucy for her present 之略。按照英語語法，its time 后從句通常要用過去式。

　　【答案】B

　　18.

　　【解析】第一空填 knew，因?yàn)?I wish 后的賓語從句要用虛擬語氣(即用過去式表示現(xiàn)在的想法);第二空要填lives，即用陳述語氣，因?yàn)?where he lives 是一個(gè)客觀事實(shí)，而不是 I wish 的內(nèi)容。

　　【答案】B

　　19.

　　【解析】 此題涉及錯(cuò)綜時(shí)間虛擬條件句，主句與現(xiàn)在事實(shí)相反，條件句與過去事實(shí)相反。句意為：要不是在七歲時(shí)就迷上了 Melinda Cox 圖書館，我真不能想像我如今會(huì)在做什么。

　　【答案】B

　　20.

　　【解析】without 引出的介詞短語為一個(gè)與現(xiàn)在事實(shí)相反的含蓄條件句。

　　【答案】A

　　21.

　　【解析】句意：萬一你被解雇，給你的醫(yī)療救助和其它方面的福利也不會(huì)被取消。

　　【答案】B

　　22.

　　【解析】句意：你想象不到這么一個(gè)表現(xiàn)良好的紳士竟然會(huì)對(duì)一個(gè)女士這么粗魯。

　　【答案】C

　　23.

　　【解析】shall此處表示警告。

　　【答案】A

　　24.

　　【解析】B此處考查情態(tài)動(dòng)詞表示推測(cè)的用法。should have done表示過去應(yīng)該做而實(shí)際并沒有做，因此淘汰A項(xiàng)。would不用來表推測(cè)，因此淘汰C項(xiàng)。B基與D項(xiàng)雖然都可以表示推測(cè)，但B項(xiàng)表肯定意義而D項(xiàng)表示否定推測(cè)，意為不可能，根據(jù)句意：他肯定已完成了他的工作;不然，他就不會(huì)在海邊玩得那么愉快了。可知此處需要肯定意義，因此淘汰D項(xiàng)。

　　25.

　　【解析】B本題考查情態(tài)動(dòng)詞的用法。must表示推測(cè)只能用于肯定句，否定句用can或could 代替。shouldnt have done 表示本來不該而實(shí)際上卻做了某事.neednt have done表示本來不必而實(shí)際上卻做了均不合題意。本句的意思是：當(dāng)事故發(fā)生時(shí)我不可能超過6歲。

　　26.

　　【解析】C should(按道理)應(yīng)該;句意：既然你在駕校時(shí)做了大量練習(xí)，那么通過這次考試?yán)聿粦?yīng)該有困難。

　　27.

　　【解析】B 第一句話使用了一般過去時(shí)，由此可知第二句話是對(duì)過去事情的猜測(cè)，需用must have done.本題意為我正在高速公路上行駛，這時(shí)一輛警車跟隨著著這輛車從旁邊經(jīng)過。它們一定是以至少每小時(shí)150公里的速度行駛。故選B。A項(xiàng)表示本應(yīng)該，C項(xiàng)表示本能夠不合題意。

　　28.

　　【解析】D 本題考查情態(tài)動(dòng)詞的用法。句意是我錯(cuò)拿了別人的綠色 毛衣，那可能是Harry的，他總是穿綠色的毛衣。四個(gè)選項(xiàng)中could表示推測(cè)。mustnt 表示 禁止has to 表示不得不will 表推測(cè)時(shí)，表肯定語氣太強(qiáng)。

　　29.

　　【解析】B根據(jù)句意可知Catherine對(duì)對(duì)方為她打掃了房間表示感謝并提到對(duì)方本來不必為她打掃房間。很顯然對(duì)方打掃房間是過去所為，表達(dá)去不必做某事用neednt have done sth.

　　30.

　　【解析】C本題考查情態(tài)動(dòng)詞，從答語的后半句我已經(jīng)借到一本字典了，可知前半句為不必了。故C正確。
