文檔簡介
第一篇詞法八、動(dòng)詞(一)知識概要?jiǎng)釉~在語言中是必不可少的一部分。它的語法現(xiàn)象也較多,但在初中范圍主要有以下幾方面問題。①時(shí)態(tài):初中范圍主要有一般現(xiàn)在時(shí),一般過去時(shí),現(xiàn)在完成時(shí),過去完成時(shí),將來時(shí)與過去將來時(shí)六種時(shí)態(tài)。②語態(tài):主動(dòng)語態(tài)與被動(dòng)語態(tài)。③助動(dòng)詞和情態(tài)動(dòng)詞。④非謂語動(dòng)詞,也就是不定式,動(dòng)名詞及現(xiàn)在分詞的用法。時(shí)態(tài)主要掌握以下幾種時(shí)態(tài)的應(yīng)用要點(diǎn)和習(xí)慣用法。1一般現(xiàn)在時(shí):主要有以下三方面,①用來表示狀態(tài),特征或不受時(shí)間限制的客觀存在和真理。如:Matterexistsinthreestates物質(zhì)有三態(tài)。又如:Theearthmovesaroundthesun②表示習(xí)慣性和經(jīng)常發(fā)生的動(dòng)作,如:Ioftengotobedat9∶30③在時(shí)間、條件等狀語從句中表示將來要發(fā)生的動(dòng)作,如:AssoonasIgetthereI'lltelephoneyou.2一般過去時(shí):①主要用于表達(dá)過去時(shí)間內(nèi)發(fā)生的動(dòng)作或存在的狀態(tài),如:Iwasilllastweek②過去經(jīng)常發(fā)生的動(dòng)作或習(xí)慣性動(dòng)作,如:Iusedtogetupatsix.3一般將來時(shí):用于表示將要發(fā)生的動(dòng)作,其構(gòu)成方式①用will(shall)+動(dòng)詞原形來表達(dá)將來在某一時(shí)間內(nèi)要發(fā)生,或經(jīng)常、將要發(fā)生的動(dòng)作或狀態(tài),如:SchoolwillbeginonSepember1st②用begoingto+動(dòng)詞原形,用來表示不久將要發(fā)生或打算去作的動(dòng)作。如:I'mgoingtoswimthisafternoon③be+現(xiàn)在分詞,也就是用某些動(dòng)詞的現(xiàn)在進(jìn)行時(shí)表示將來,如:I'mcoming。這些動(dòng)詞只限于:go,come,leave,start,move,sail,arrive,reach,getto等動(dòng)詞。④在狀語從句中用一般現(xiàn)在時(shí)表示將來。4現(xiàn)在進(jìn)行時(shí):用于表示現(xiàn)在正在進(jìn)行的動(dòng)作,如:Whatareyoudoingnow?要注意的是表示狀態(tài),情感的某些詞沒有現(xiàn)在進(jìn)行時(shí),這些動(dòng)詞有:like,have(有),love,know,understand,remember,forget,see,hear,smell,taste,feel,wishhope,expect…5過去將來時(shí):用來表達(dá)從過去某時(shí)間點(diǎn)上看將要發(fā)生的動(dòng)作,如:Hetoldmehewouldcometomyparty6現(xiàn)在完成時(shí)與過去完成時(shí):現(xiàn)在完成時(shí)的兩個(gè)用處是:①用來表達(dá)在過去開始的動(dòng)作持續(xù)到現(xiàn)在,如:I'vestudiedEnglishfortwoyears②用來表達(dá)過去發(fā)生的事但它影響到現(xiàn)在,如:Ihaven'thadmybreakfast.soI'mhungrynow現(xiàn)在完成時(shí)與過去完成時(shí)的區(qū)別在于動(dòng)作的截止時(shí)間,現(xiàn)在完成時(shí)所表達(dá)的動(dòng)作截止于現(xiàn)在,而過去完成時(shí)所表達(dá)的動(dòng)作截止于過去。如:Ihaven'tseenmyoldteacherforalongtime我好久未見到我過去的老師了。是指到目前截止。如果加上一句話,則將變?yōu)檫^去完成時(shí),如:YesterdayIsawmyoldteacher.Ihadn'tseenhimforalongtime.因?yàn)槲液镁梦匆娝@一情況截止于昨天。還要注意的一個(gè)問題是截止性動(dòng)詞可以有完成時(shí),但不能與表示一段時(shí)間的狀語連用,如:WhenIgottoschool,theclasshadbegun如果一定要講開始幾分鐘了則要換用表示狀態(tài),或延續(xù)性動(dòng)詞,如:WhenIgottoschool,theclasshadbeenonforfiveminutes語態(tài):英語中只有主動(dòng)語態(tài)與被動(dòng)語態(tài)之分。主動(dòng)語態(tài),句子中的主語是動(dòng)作的執(zhí)行者,如:Ibrokethewindow而被動(dòng)語態(tài)句子中的主語是主動(dòng)語態(tài)句子中的賓語,如:Thewindowwasbrokenbyme被動(dòng)語態(tài)主要用于,動(dòng)作的執(zhí)行者不明確,或沒有必要說出來,如:TheNewbuildingwasbuiltlastweek關(guān)鍵要注意的是在主動(dòng)語態(tài)中有省略不定式符號to的動(dòng)詞,在被動(dòng)語態(tài)要還原,如:主動(dòng)語態(tài)Isawhimcomein.被動(dòng)語態(tài)Hewasseentocomein.助動(dòng)詞和情態(tài)動(dòng)詞:助動(dòng)詞本身沒有詞義,它只不過與實(shí)義動(dòng)詞一起構(gòu)成謂語動(dòng)詞,形成了時(shí)態(tài)、語態(tài)、構(gòu)成了疑問句,否定句,以及用來加強(qiáng)語氣。而情態(tài)動(dòng)詞則表達(dá)一種可能、必要、允許、愿望、猜測……的意圖、傾向。也用來表示語氣的委婉和祝愿。初中階段主要有:can,could,may,might,will,would,must(haveto),shall,should。最后要談?wù)摰氖欠侵^語動(dòng)詞,非謂語動(dòng)詞分為不定式,和動(dòng)詞的ing形式,(即現(xiàn)在分詞和動(dòng)名詞)。雖然在初中范圍,這一項(xiàng)不是語法重點(diǎn),但還是要花一定時(shí)間去學(xué)習(xí),為的是打下良好的基礎(chǔ)。為進(jìn)一步學(xué)習(xí)提供良好的條件。不定式在句中可以作主語、賓語、表語。如:Toseeistobelieve.(百聞不如一見)Hewanttoseeafilm還可以作補(bǔ)足語,如:Hewantsmetoleave.也可以作狀語,如:IcomeheretolearnEnglish.動(dòng)名詞也可以起到上述作用,如:Seeingisbelieving.Ilikeswimmingverymuch.而現(xiàn)在分詞多用于作定語、補(bǔ)足語、狀語,如:Thegirldrivingacarishersister.(定語)Didyounoticehishandshaking?(賓語補(bǔ)足語)Hearingthenoise,westoppedtalking.(狀語)(二)正誤辨析[誤]Shelaiddownandsoonfellasleep.[正]Shelaydownandsoonfellasleep.[析]考試中常出現(xiàn)的是易混動(dòng)詞lay放,lie躺,lie說謊。它們的過去時(shí)、過去分詞和現(xiàn)在分詞變化如下:lay(放)laid,laid,laying(及物動(dòng)詞)lie(躺)lay,lain,lying(不及物動(dòng)詞)lie(說謊)lied,lied,lying[誤]Pleaseriseyourhand.[正]Pleaseraiseyourhand.[析]rise是不及物動(dòng)詞,其后不能接賓語,如:Thesunrisesintheeast.而raise是及物動(dòng)詞。[誤]Iliketoswimverymuch,butIdon'tlikeswimmingthisafternoon.[正]Ilikeswimmingverymuch,butIdon'tliketoswimthisafternoon.[析]like作為"喜歡"講時(shí),可以接動(dòng)名詞也可以接不定式,但接動(dòng)名詞時(shí)多表達(dá)一種習(xí)慣性動(dòng)作。而接不定式則側(cè)重于表達(dá)一次性、特殊性的動(dòng)作。但要注意的是like與would連用時(shí)則一定要接不定式,如:Wouldyouliketogowithme?再有一點(diǎn)要注意的是,like作為介詞"像"講時(shí),只能用分詞作其賓語。[誤]Stop!Didyoulistentoastrangevoice?[正]Stop!Didyouhearastrangevoice?[析]hear的側(cè)重點(diǎn)是聽到、聽見什么,而listento的側(cè)重點(diǎn)為聽的傾向,如:listen!Doyouhearsomeonecallinghelp?這樣的詞還有l(wèi)ook與see。它們的側(cè)重點(diǎn)也不同,look重于"看"的傾向,而see重于看見沒看見。[誤]Didyouwatchsomefilmrecently?[正]Didyouseesomefilmrecently?[析]英語中see與watch各有不同的用處,see用于看電影、劇目,而watch用作看電視和看球賽。[誤]Look.Abeautifullamphangedfromtheceiling.[正]Look.Abeautifullamphungfromtheceiling.[析]hang有兩個(gè)含義,①"掛",它的過去時(shí)與過去分詞是hung,hung;②"絞刑",這時(shí)它是規(guī)則動(dòng)詞,其過去式與過去分詞則為hanged,hanged。[誤]Themeathasgonebadly.[正]Themeathasgonebad.[析]英語中g(shù)o,get,become,turn作為轉(zhuǎn)變時(shí),其后接形容詞,這時(shí)這些動(dòng)詞應(yīng)被看作系動(dòng)詞。[誤]Theteachersaidtheearthmovedaroundthesun.[正]Theteachersaidtheearthmovesaroundthesun.[析]如果主句的謂語動(dòng)詞是現(xiàn)在時(shí),其賓語從句可以是任何時(shí)態(tài)。如果是過去時(shí),則賓語從句中的時(shí)態(tài)應(yīng)與之呼應(yīng)。但地球圍繞太陽轉(zhuǎn)是不隨時(shí)間而變化的客觀事實(shí),所以還應(yīng)用一般現(xiàn)在時(shí)態(tài)來表達(dá)。[誤]I'llcometoseeyouassoonasI'llbebac
