高一英語(yǔ)情態(tài)動(dòng)詞專(zhuān)題訓(xùn)練及答案

高一英語(yǔ)態(tài)動(dòng)詞專(zhuān)題練概說(shuō)助動(dòng)詞auxiliary)主有兩類(lèi)：基本助動(dòng)詞和情態(tài)助動(dòng)(modalauxiliary)基本助動(dòng)詞有三個(gè)do,和be態(tài)助動(dòng)詞有十三個(gè)may,might;could;will,must,need,dare,to,oughtto.上兩類(lèi)助動(dòng)詞的共同特征是助動(dòng)詞構(gòu)成限定動(dòng)詞詞組時(shí)，具有作用詞的功能：）構(gòu)否定式：HedidntandneitherThemeetingnotuntil5）構(gòu)疑問(wèn)式或附疑問(wèn)式：Mustleavenow?havebeenFrenchfor5years,t）構(gòu)修辭倒裝：obtainanyHardlyhadwhen）代限定動(dòng)詞詞：A:Whothiscrosswordpuzzle?B:can.A:ShallIwriteB:do情助詞特基本助動(dòng)詞與情態(tài)助動(dòng)詞最主要的區(qū)別之一是本助動(dòng)詞本身沒(méi)有詞義情助動(dòng)詞則有自己的詞義，能表示說(shuō)話人對(duì)有關(guān)動(dòng)作或狀態(tài)的看法，或表示主觀設(shè)想：What（成完成行體，本身無(wú)詞義）IamafraidIbegoing.（一定要）havereadsomematter.（許已經(jīng)）除此之外，情態(tài)助動(dòng)詞還有如下詞法和句法特征：）除和used以，其他情態(tài)動(dòng)詞后面只能接不帶的定式。如果我們把oughtto和used看是固定詞組的話那么，所有情態(tài)動(dòng)詞無(wú)一例外地只能接不帶to的不定式：WeusedbeautifulIaskedifcome）情助動(dòng)詞在限動(dòng)詞詞組總總是位居第一：needbeenpunishedso）情助動(dòng)詞用于三人稱(chēng)單數(shù)現(xiàn)在時(shí)的時(shí)候，沒(méi)有詞形變化，即其詞尾-s式：Shedarenotwhatshethinks.）情動(dòng)詞沒(méi)有非定形式，即沒(méi)有不定式-ing分詞和-ed分形式：Still,she’thaveaway.）情助動(dòng)詞的“”的形式并不是時(shí)間區(qū)別的主要標(biāo)志。在不少場(chǎng)合，情態(tài)助動(dòng)詞的現(xiàn)在時(shí)和過(guò)去時(shí)形式都可以表示現(xiàn)在、過(guò)去或?qū)?lái)時(shí)間：veryifIasksomething?

toldhimoughtnottohaveit.）情助動(dòng)詞之間相互排斥的，即在一個(gè)限定動(dòng)詞詞組中只能出現(xiàn)一個(gè)情態(tài)助動(dòng)詞，但有時(shí)卻可以與和基助動(dòng)詞連用：shouldhavethewound.Well,shouldnbea現(xiàn)將情態(tài)助動(dòng)詞的各種形式列表如下：肯式will,’llwould,’need

否式notnotcannotwillllnotwouldnotnotneednottoto

簡(jiǎn)否式tmightnttcouldntwontttttneedntdarenttuse(d)tottotto情助詞意和法情態(tài)助動(dòng)詞從最普通的意義上來(lái)說(shuō)修飾分句意義的一種方式可反映說(shuō)話者對(duì)其表述是否真實(shí)和可能的程度作出判斷。但不同的情態(tài)助動(dòng)詞本身所包含的意義和用法又不同，下面逐個(gè)分析。）和could的法．表能力或客觀能性，還可以表示請(qǐng)求和允許。如：Canyoufinishthisworktonight?Mancannotliveair.—Inow?—Yes,youcan注意：也表示請(qǐng)求，預(yù)期委婉主要用于疑問(wèn)句，不可用于肯定句，答語(yǔ)應(yīng)用（即could不用于現(xiàn)在時(shí)態(tài)的簡(jiǎn)略答語(yǔ)中：CouldIcomeseetomorrow?you（定答語(yǔ)可用No,Iafraid）②can表能力時(shí)，還可用代。如：Illnotbeablecome．表驚異、懷疑不相信的態(tài)度要用在否定句、疑問(wèn)句或驚嘆句中）CanthisbeHowcanyoubeThisdoneby．“can(could)+have過(guò)去分詞”的疑問(wèn)或否定形式表示對(duì)過(guò)去發(fā)生的行為懷疑或

不肯定。如：Hecannothavebeenthattown.Canhehavegot）may和might的法．表許可。表示請(qǐng)求、允許時(shí)，might比many的氣更委婉一些，否定回答要用t表示“不可以之。如：car.—MightI—No,mustn’用MayI...征詢(xún)對(duì)方許可在文體上比較正式，在口氣上比較客氣。在日常口語(yǔ)中，用I...征詢(xún)對(duì)方意見(jiàn)在現(xiàn)代口語(yǔ)中更為常見(jiàn)。．用祈使句中表祝愿。如：Maysucceed!．表推測(cè)、可能疑問(wèn)句不能用于此意Hemaybeverybusynow.．“may(might)++過(guò)分詞”表示對(duì)過(guò)去發(fā)生的行為的推測(cè)。如：Hemayhavefinishedthework.）must和的法．表必須、必要如：comeintime.回答must引的問(wèn)句時(shí)，如果是否的回答，不能t，而要用tdontto—wehandinourexercisetoday?—Yes,.(No,dontto.)．“must表語(yǔ)”的結(jié)構(gòu)表示推測(cè)，它的否定或疑問(wèn)式用代。Thismustbepen.．“must+have+過(guò)分詞結(jié)構(gòu)常用在肯句中對(duì)過(guò)去發(fā)生的行為的推測(cè)。它的否定或疑問(wèn)式用代must。He．haveto含義與must相似者往往可互換使用have各種形式have的變化而定must與haveto下列幾點(diǎn)不同：①must表示的是說(shuō)話人的主觀看法，而haveto則往強(qiáng)調(diào)客觀需要如：Theinteresting.Ireallygonow.ItoworkI②must一般只表現(xiàn)在有更多的時(shí)態(tài)形式。③二的否定意義不大相同。如：mustnt你不要去t你必去。④詢(xún)對(duì)方的意愿時(shí)應(yīng)用must。：MustIcleanallthe

）和的用．need表“需要”或“必須情動(dòng)詞時(shí)，僅用于否定句或疑問(wèn)句中，在肯定句中一般用to,或代替。如：’tsoearly.—Ifinishthework—Yes,.注意：neednt不定式的完成式“表示本來(lái)不必做某事而實(shí)際上做了某事’thavewaitedforme.．Dare作態(tài)動(dòng)詞時(shí)要于疑問(wèn)句定和條件從句般用在肯定句中。如：HowdaresayImHetdare．Dare和常作實(shí)義動(dòng)詞，有時(shí)態(tài)、人稱(chēng)和數(shù)的變化，所不同的是，作實(shí)義動(dòng)詞時(shí)，在肯定句中dare后通常接帶to的定式，在否定和疑問(wèn)句中后可接帶to或帶的定式。如：Itoswimacrossriver.He(to)tit!Ihe(to)that.Heneedstofinishitthisevening.）shall和用法．用第一人稱(chēng)，表示征求對(duì)方的意愿。如：Whatshallevening?．用第一三人稱(chēng)疑問(wèn)句中示話人征求對(duì)方的意見(jiàn)向?qū)Ψ秸?qǐng)示weourlesson?shallheleavethehospital?．用第二、第三人稱(chēng)，表示說(shuō)話人給對(duì)方命令、警告、允諾或威脅。如：Youiftwork（告）shallbookIfinish（諾）shall（脅）．Should表勸告、建議、命令，其同義詞是；疑問(wèn)句中，通常用代替。如：shouldclassrightShouldIopenthewindow?含義較多，用法較活，現(xiàn)介紹三種其特殊用法。請(qǐng)看下面的句子：①I(mǎi)itbettertotryit我是認(rèn)為最好再試一試。②Youmistaken,Ishouldsay.依看，你是搞錯(cuò)了。③Iadviseyounottodo我是勸你別這樣做④ThisItoask這我本來(lái)想問(wèn)你的。從以上例句可以看出：情態(tài)動(dòng)詞should用第一人稱(chēng)時(shí)可以表示說(shuō)話人的一種謙遜、客氣、委婉的語(yǔ)氣。可以用在if引的條件從句表一件事聽(tīng)起來(lái)可能性很小也不是完

全沒(méi)有可能。相當(dāng)于“萬(wàn)一”的意思。從句謂語(yǔ)hould加詞形構(gòu)成，主謂語(yǔ)卻不一定用虛擬語(yǔ)氣。如：⑤Askhertoringupifyou你一見(jiàn)到她給我打個(gè)電話。⑥Ifshouldchangeyourmind,pleaseletus萬(wàn)你改變主意，請(qǐng)通知我們。⑦ShouldI(IfIshould)freetomorrowIwillcome.萬(wàn)一我明天有時(shí)間，我就來(lái)。此外，How)+結(jié)構(gòu)表示說(shuō)人對(duì)某事不能理解，感到意外、驚異等意思。意為“竟會(huì)：⑧Whysolatetoday?你天怎么來(lái)得這么晚？⑨—isBettyliving?—貝蒂住在哪里？—HowIknow?—我怎么會(huì)知道呢？⑩IdonknowyoushouldthinkthatIdidit.我不知道你憑什么認(rèn)為這件事是我干的。．“+過(guò)去分詞構(gòu)般示義務(wù)示該做到而實(shí)際上沒(méi)有做到，并包含一種埋怨、責(zé)備的口氣。如：finishedit.Iher,butIshouldhavestarted）willwould的法．表請(qǐng)求、建議would比will委客氣。如：passme．表意志、愿望決心。如：Idoifwewoulddothat．用will”和+過(guò)分詞”的結(jié)構(gòu)表示推測(cè)，主要用于第二、三人稱(chēng)。前者表示對(duì)目前情況的推測(cè)，后者表示對(duì)已經(jīng)完成的動(dòng)作或事態(tài)的推測(cè)。如：ThiswillbookHearrivedbynow.TheguestswouldhavebyIthoughtyoufinishedthisby．可表示過(guò)去反復(fù)發(fā)生的動(dòng)作或某中傾向表去習(xí)慣時(shí)比正，并沒(méi)有“現(xiàn)已無(wú)此習(xí)慣”的含義。如：Thewouldnotheal.Duringvacationhemeevery．表想或猜想。：ItbeaboutwhenleftWhatwouldshebedoingIthoughtheallaboutit.）oughtto的法．to表應(yīng)該。如：

oughttohim.．表推測(cè)。注意must表推測(cè)時(shí)的區(qū)別：Hebeatby（定他已到家Heoughttohomebynow.（不十分肯定）Thisiswheretheoil（較直率Thisiswheretheoiltobe（比較蓄）．“++過(guò)分詞”表示過(guò)去應(yīng)做某事而實(shí)際未做。如：oughtto(butyoudidnt).這時(shí)，should可互相換。注意：在美國(guó)英語(yǔ)中oughtto用否定句和疑問(wèn)句時(shí)，可省略。如：Oughtyououghtntmuch.），hadbetter，rather的法．Used示過(guò)去的習(xí)慣動(dòng)作或狀態(tài)在已不在間引語(yǔ)中形可不變。如：Heustowhenwas在疑問(wèn)句、否定句、否定疑問(wèn)句或強(qiáng)調(diào)句中，可有兩種形式：疑句否句

youusegotosameUsedsameIusednttothere.I’tgot亦可拼作t但發(fā)音皆[ju:znt]。否疑句強(qiáng)句

ttobeinterestedintyouusebeintheIcertainlytosmoke,itwaslongago.Icertainlydidsmoke,butitatimeago.其反意疑問(wèn)句或簡(jiǎn)略回答中，也有兩種形式：usedtoveryfat,didn’t（正式/tshe?（語(yǔ)）Didyouusetoplaychess?Iupinmorning?IdidIused．Had意“最好接不帶to的不定式。如：—hadbettergonow.—Yes,(webetter/better).’twestop(HadIIdbetterbegoing.（用于進(jìn)行時(shí)態(tài)，表“最好立即haddone（于完成時(shí)態(tài)，表未完成動(dòng)作）注①best與had同意但少用②hadbetter用同輩或小輩，對(duì)長(zhǎng)輩不可用。．Wouldrather意為“寧愿選，后接不帶to的定式。如：I’rathernotsayratherworkafarm?
