2019-2020年高考英語 專題講練五 情態(tài)動詞和虛擬語氣 　　【考點(diǎn)分析】 　　情態(tài)動詞 　　1.考查情態(tài)動詞的基本用法 　?、賡hall用于一、三人稱疑問句表示征求對方意見;用于二、三人稱陳述句表示說話人給對方的命令、警告、允諾或威脅等;may表示“允許、可以”，語氣比較委婉。 　?、趍ust用于疑問句，表示責(zé)備、抱怨的感情色彩，意思為“偏偏，偏要”，mustn’t表示禁止，是說話人強(qiáng)有力的勸告。cannot 表示“不可能”;need not 表示“不必要”;may not 表示“可能不，可以不”。 　?、踤eedn’t表示“沒有必要” 　　④would表示過去反復(fù)發(fā)生的動作或某種傾向 　?、荼硎窘?jīng)過努力而成功的某一次動作，只能用was/were able to,而不能用could;could還可以表示過去的某種能力 　?、蘅疾榍閼B(tài)動詞用作答語的情況 　　2.考查情態(tài)動詞+動詞不定式一般式表推測的用法 　?、倏隙ǖ耐茰y一般用must,should,may(might)或could(不用can)，其中，must的語氣最強(qiáng)，譯為“肯定”、should的語氣次之，譯為“很可能”、“應(yīng)該”;按常理推測的may(might),could語氣最弱，譯為“也許”。 　?、诜穸ǖ耐茰y：語氣不很肯定時，常用may not,might not或could not，譯為“可能不”“也許不”;否定語氣較強(qiáng)時，則用can’t，譯為“根本不可能”、“想必不會”，表示驚異、懷疑的感情色彩 　　③疑問句中推測往往用can或could 　　3.考查情態(tài)動詞+動詞不定式的完成式表推測的用法 　　4.考查情態(tài)動詞+動詞不定式完成式的其他用法 　?、賡hould(ought to)+不定式的完成式：本來應(yīng)該做而實(shí)際上又沒有做。其否定形式表示某中行為不該發(fā)生卻發(fā)生了。 　?、趎eedn’t+不定式的完成式：本來不必要做的而實(shí)際上又做了 　?、踓ould+不定式的完成式：本可以做而實(shí)際上未能做,含有遺憾的意味 　　虛擬語氣 　　1.虛擬條件句的基本結(jié)構(gòu)及其用法 ①與現(xiàn)在事實(shí)相反的虛擬條件句②與過去事實(shí)相反的虛擬條件句 ③與將來事實(shí)相反的虛擬條件句 　　2.虛擬語氣的活用 　?、贂r間錯綜虛擬結(jié)構(gòu) 　?、谑÷詉f的虛擬結(jié)構(gòu) 　?、鄄⒘羞B詞或副詞暗示的虛擬結(jié)構(gòu) 　?、芙樵~或介詞短語暗示的虛擬結(jié)構(gòu) 　　⑤as if / as though方式狀語從句中的虛擬語氣 　?、廾~性從句中的虛擬語氣 　?、叻衷~短語暗示的虛擬結(jié)構(gòu) 　　⑧上下文語境中的虛擬結(jié)構(gòu) 　　【知識點(diǎn)歸納】 　　I.情態(tài)動詞 　　1.表示“能力、許可”的can /may 　　①表示能力的情態(tài)動詞用can/could 　　A puter_____think for itself, it must be told what to do. 　　A.can’t B.couldn’t C.may not D.might not 　?、诒硎驹S可時用may/might ,can/could 都可以，但在問句中用could…? 　　或might…? 以使口氣委婉客氣，其回答一定要用can或may，以使回答口氣明確(must表示一定，必須，mustn’t表示禁止，不許可) 　　—Could I call you by your first name? —Yes, you______ 　　A.will B.could C.may D.might 　　Johnny, you_____play with the knife, you_____hurt yourself. 　　A. won’t/can’t B.mustn’t/may C.shouldn’t/must D.can’t/shouldn’t 　?、墼诳隙ň渲衏ould不可以用來表示過去某一特定場合的能力，而要用was/were able to。 　　如不可以說：They could jump into the sea before the boat was blown up 　　而要說：they were able to/managed to jump into… 　　The fire spread through the hotel very quickly but everyone_____get out. 　　A.had to B.would C.could D.was able to 　　但在否定句中could/was(were)able to可以通用: 　　I couldn’t/wasn’t able to see him yeaterday. 　?、鼙硎驹S可時用may/can都可以。只不過用may時較側(cè)重講話人的許可，而can較側(cè)重客觀情況的許可，must則表示必須做某事。 　　2.表示“推斷、判斷”的can,may,must 　　①在肯定句中都可以用來表示可能。在含義上must語氣最為肯定,may表示的是事實(shí)上的可能性： 　　Peter______e with us tonight, but he isn’t very sure yet. 　　A.must B.may C.can D.will 　　而can表示的是邏輯上的可能性：Mary is in poor health. She can be ill at any times. 　　②在否定句中只能用can和may。此時can’t用以代替mustn’t，語氣比may not更強(qiáng)。can’t中文可以翻譯為“不可能”、may not中文可以翻譯為“可能不”。 　　Michael______be a policeman, for he’s much too short. 　　A.needn’t B.can’t C.should D.may 　　③在疑問句只能用can，不能用may和must 　　He may be very busy now. Can he be very busy now? 　　He must be very busy now. Can he be very busy now? 　　3.表示“請求、提議”(用在疑問句中)的can和could，這時could比can語氣更婉轉(zhuǎn) 　　Can(Could)you give me a lift to the station? 　　你(您)能不能讓我搭你(您)的車去車站呀? 　　4.表示“驚訝、懷疑”(用在疑問句中)的can和could，這時could比can語氣更婉轉(zhuǎn) 　　Who can it be at this time of day?這個時候到底會是誰呢? 　　5.構(gòu)成下列特殊句式的can 　?、賑an not/can never…too… cannot…enough“無論怎么……也不為過分，越……越好，非常……” 　　Since it is a good thing,we cannot do it too soon. 　　既然是好事情，我們越早開始做越好。 ②can’t help doing…,cannot help but do…,cannot but do…“禁不住，不由得，不得不” I cannot help admiring the picture whenever I look at it.每當(dāng)我看到這幅畫時，我都禁不住要鑒賞它。 　　When a close friend dies,you cannot but feel sad. 　　親密的朋友去世時，你會不由得感到悲傷。 　　6.表示祝愿、祝福的may,此時句子用倒裝語序 　　May he live to an old age!愿他長命百歲!May God be with you!愿上帝保佑你! 7.shall/should 用于人稱 意義 Shall 第一、三人稱 征求對方的意見 第二、三人稱 說話人給對方的警告、命令、允諾、威脅 用于法律、法規(guī)等條文中 應(yīng)……，須……，得…… 　　What shall we do this evening? 　　注意：may用于征求對方的許可，而shall用于征求對方的意見或指示： 　　May I have a look?我能看一看嗎? 　　Shall I have a look?需要我看一看嗎? 　　You shall fail if you don’t work harder.
