語法重點復(fù)習(xí)(非謂語動詞)(狀語從句)(定語從句)(倒裝句)講義

語法重點復(fù)習(xí)----非謂語動詞一．基本概念：什么是謂語動詞(動詞的謂語形式)?什么是非謂語動詞(動詞的非謂語形式)?在英語中可以充當(dāng)句子謂語的詞必須是動詞,而這個動詞形式又必須與句子的主語間保持著正確的人稱,數(shù),及語態(tài),時態(tài)的變化關(guān)系,即:主語的人稱,數(shù),時間,及主語與動詞之間的主動發(fā)出或被動反射關(guān)系,這一正確的變化關(guān)系就是動詞的謂語形式,也是我們判斷句中的謂語形式正確與否的依據(jù).(*注意:以please構(gòu)成的祈使句通常是省去主語的,但句中的動詞仍是謂語形式!(Please)standup!Look!Don’tmove!)需特別注意的是:盡管句中的謂語必須用動詞充當(dāng),但并非句中的每一個動詞都是動詞的謂語形式.如:HewentNanjingtoseehisbrotherlastweek.(tosee)Whathesaidmadeusthinkabouttheproblem.(think)Tomenjoysswimminginsummer.(swimming)Mywatchdoesn’twork,whichIwillhaverepaired.(repaired)從以上例句中可看出動詞形式:tosee,think,swimming,和repaired有以下特點:與句子的主語之間并無正確的人稱,數(shù),等關(guān)系,即:不隨主語的變化而變化仍有動詞的明顯特征,如:動作意義,主被動含義(注意:不是主被動語態(tài))*結(jié)論:這種與句子的主語之間無人稱,數(shù)的變化關(guān)系,但又有著動詞固有的特征的動詞形式---一個不能充當(dāng)謂語的動詞形式,就是動詞的非謂語形式(非謂語動詞).因此,解與動詞有關(guān)的題目時,首先考慮的就是:此處該用謂語還是非謂語?!2.非謂語動詞的表現(xiàn)形式---哪些動詞形式是非謂語形式?基本形式主動變形形式被動變形形式todotobedoingtohavedonetobedonetohavebeendonedoinghavingdonehavingbeendonedone注意:1.)動詞的單三人稱,如:goes和過去式,如:went一類的動詞形式,永遠是謂語形式.難點是:很多動詞的過去式的拼寫與過去分詞(done)完全一樣,所以很容易混淆.動詞原形既可充當(dāng)謂語(但僅限于一般現(xiàn)在時,非單三人稱做主語時,以及一些情態(tài)動詞之后),又可充當(dāng)非謂語,要注意辨別二．非謂語動詞的語法功能----在句中所充當(dāng)?shù)某煞郑篈.作主語:非謂語動詞形式中的todosth,tobedone,doingsth,havingdonesth,beingdone,havingbeendone在句中可充當(dāng)主語，使用要點如下：Dosth不可作主語.X:Getupearlyisagoodhabit.---Gettingupearlyisagoodhabit.Doingsth作主語與Todosth作主語的區(qū)別是:Doingsth常表示一個習(xí)慣上的,經(jīng)常發(fā)生的動作;而Todosth則表示一個具體的,某一時刻發(fā)生的動作.試比較:Goingswimmingonahotsummerdayisapleasure.(習(xí)慣性,經(jīng)常性)Togoswimmingwithyoutodayisapleasure.(具體性)被動態(tài)的doing,即:beingdone作主語時,being不可省略,done不可直接作主語.X:Blamedforbreakingtheunvaluablecupmadehimannoyed.---Beingblamedforbreakingtheunvaluablecupmadehimannoyed.如要明確表示doing是誰發(fā)出的或beingdone反射到誰身上,必須在doing,beingdone前面+sb’s/sth’s(所有格)Thathecamelateforclassmadetheteacherangry.SP=Hiscominglateforclassmadetheteacherangry.SPThattheenvironmentiswellprotectedisimportant.SP=Theenvironment’sbeingwellprotectedisimportant.SPDoingsth,Todosth作主語時,句中謂語必須用單數(shù),不要受緊貼謂語的的名詞的干擾:Eatingmorefruitandvegetablesisgoodforourhealth.B.作表語:(在系動詞后面,主要是用:todo,doing,done)Hisjibiscleaningtheschool.Hispurposeistowinthefirstprize.Luckily,nobodygotinjuredintheaccident.Glasswallslooksowelldesignedbutwemayfeeluninvited/refused.C.作賓語:所謂非謂語動詞作賓語,就是將一個非謂語動詞形式放在句中的謂語后面構(gòu)成:主+謂(P)+動詞(v)+其他的句式,即:一個動+動的句式,其分類如下:1.普通類:S+P+todo/tobedone+其他.注意:英語中大多數(shù)的動詞后只可用todo,tobedone作賓語(例外:helptodo/dosth),但某些動詞,詞組后則可用不定式的各種變形形式作賓語,所以必須牢記這些動詞和詞組:表一.主語謂語可用動詞賓語:不定式主動變形形式賓語:不定式被動變形形式Sb/sth+seemappearhappenpretendtodosthtobedoingtohavedonetobedonetohavebeendone(1)Hepretendedtoworkhardafterhefailedintheexam.(towork發(fā)生在謂語pretended之后)(2)Hepretendedtobeworkinghardwhentheemployercamein.(tobeworking與謂語pretended同時發(fā)生)(3)HepretendedtohaveknownthenewswhenIshowedhimthenewspaper.(tohaveknown發(fā)生在謂語pretended之前)(4)Allthefoodmayhappentobeeatenwhenwegettheparty,I’mafraid.(tobeeaten發(fā)生在謂語happen之后)(5)Allofthemhappenedtobehavingdinnerwhenwegottotheparty.(tobehaving與謂語happened同時發(fā)生)(6)Allthefoodhappenedtohavebeeneatenwhenwegottotheparty.(tohavebeeneaten發(fā)生在謂語happened之前)表二.主語謂語可用動詞賓語:不定式主動變形形式賓語:不定式被動變形形式Sb/sth+besaidbethoughtbesupposedbeconsideredbebelievedbereportedbeknowntodosthtobedoingtohavedonetobedonetohavebeendone(1)HeissaidtogototheU.Stostudynextyear.(togo發(fā)生在謂語issaid之后)(2)Heissaidtobewritinganewnovelatpresent.(tobewriting與謂語issaid同時發(fā)生)(3)HeissaidtohavestudiedintheU.S.(tohavestudied發(fā)生在謂語issaid之前)表三.具有虛擬含義的不定式:在下例動詞,動詞詞組后用tohavedone,tohavebeendone來表示:某人當(dāng)時想做…,但(后來)實際未能做到.主語謂語動詞形式賓語:不定式主/被動變形形式Sb+WishedhopeWantedintendedMeantwouldlike/love(would)preferwas/weretohavedonetohavebeendone(1)Iwouldlikeverymuchtohavejoinedyouinthepicnic.(我本非常愿意和你們一起去野炊)(2)Ihoped/wanted/intendedtohavebeeninvitedtotheparty.(我真希望被邀請去參加了那個聚會)使用不定式的各種變形形式作賓語時的注意要點:(1)必須牢記哪些動詞后面可用不定式的各種變形形式作賓語.(2)準(zhǔn)確地判斷句中該用不定式的主動類(todo,tobedoing,tohavedone),還是被動類(tobedone,tohavebeendone),再判斷時間(時態(tài)含義)上的區(qū)別.因為語態(tài)含義是指不定式與句子主語之間的邏輯關(guān)系,是原則問題,而時態(tài)關(guān)系則是語境問題,是細(xì)微差別.如:Hehappened_________(call)onwhenhewasaway.Thescientistsseem______________(interest)inthisfieldforalongtime.*特殊情況中的不定式作賓語:(1)介詞but,except(除…之外)后面既可跟todosth,也可跟dosth用法為:a.)當(dāng)but/except前沒有實意動詞do的任何形式時:用todosth;Wehadnochoiceatthattimebuttogiveintohim.Hesaidnothingbut/excepttothrowhimselfintothechair.b.)當(dāng)but/except前有實意動詞do的任何形式時:用dosth:Hedidnothinginthemorningbut/exceptwatchTV.Alltheday,heseemstohavenothingtodobut/exceptchatonline.(2)wh-詞:what,who,which,when,where,how,whether,(why除外)后面都可以跟一個不定式的主動式:wh-+todo來替代一個完整的賓語從句,主語從句或表語從句:主句從句wh-詞+todoIdon’tknowwhowillgotothemeeting.(主動態(tài))whoweshouldsendtothecompany.(主動態(tài))whotogotothemeeting.主,謂關(guān)系whotosendtothecompany.動,賓關(guān)系Idon’tknowwhatwecandotostoppollution.(主動態(tài))whattodotostoppollution.動,賓關(guān)系Idon’tknowwhichbookIcanchoose.(主動態(tài))whichbooktochoose.動,賓關(guān)系*需要特別注意的是:在完整的從句中,當(dāng)wh-詞與從句的謂語為動賓關(guān)系時,仍用不定式的主動形式todo,來表示這一動賓關(guān)系,而不是用被動形式tobedone來表示.即:主動形式表示被動含義.Theyhavenevertoldmewhat_________.(選出所有錯誤).A.istodoB.to
