初中英語非謂語動(dòng)詞-動(dòng)詞不定式

一對(duì)一個(gè)性化講義本次授課內(nèi)容授課標(biāo)題非謂語動(dòng)詞一一動(dòng)詞不定式學(xué)習(xí)目標(biāo)掌握動(dòng)詞不定式作賓語、作賓語補(bǔ)足語及作目的狀語重點(diǎn)難點(diǎn)動(dòng)詞不定式作賓語補(bǔ)足語及一些相關(guān)句型的運(yùn)用本次課課堂教學(xué)內(nèi)容一、動(dòng)詞不定式的構(gòu)成及句法功能.動(dòng)詞不定式的構(gòu)成不定式的基本形式為：to+動(dòng)詞原形。有時(shí)可以不用to,這里的to是不定式符號(hào)，本身沒有意義，動(dòng)詞不定式的否定形式是“not（+to）+動(dòng)詞原形”。動(dòng)詞不定式具有名詞、形容詞和副詞的特征，因此在句中可以作主語、表語、賓語、賓語補(bǔ)足語、定語或狀語。.動(dòng)詞不定式的句法功能（1）不定式作主語用作主語的動(dòng)詞不定式通常表示一種具體的、特定的行為，其謂語動(dòng)詞用第三人稱單數(shù)形式。當(dāng)作主語的不定式（短語）較長時(shí)，用it作形式主語，而將真正的主語置于句末。例：TolearnEnglishwellisnoteasy.學(xué)好英語不容易ItisimportantforstudentstolearnEnglishwell.學(xué)好英語對(duì)學(xué)生們來說是重要的。 1 （2）不定式作賓語有些及物動(dòng)詞后用不定式作賓語，常見的這類及物動(dòng)詞有：begin、choose、continue>decide>expect、fail、forget、hate、help、hope、learn、manage>mean、need、offer、plan、prefer、pretend、promise>refUse、try、wait、want、wish、determine>dare、attempt、afford、agree、start、like。例：Shepromisedtocomeatnineo,clock.她答應(yīng)九點(diǎn)來的。如果作賓語的不定式有賓語補(bǔ)足語，常用it作形式賓語，而將真正的賓語后置。例：Ifounditimportanttogetupearlyinthemorning.我發(fā)現(xiàn)早上早起很重要。（3）不定式作定語①不定式有時(shí)起形容詞的作用，修飾名詞、代詞，在句中作定語。不定式作定語時(shí)，它的位置是在它所修飾的名詞或代詞之后。例：Hewasthefirsttocometotheclassroom.他是第一個(gè)來到教室的人。②若不定式是不及物動(dòng)詞，或不定式修飾的名詞或代詞是不定式動(dòng)作的地點(diǎn)、工具等，不定式后面就應(yīng)有必要的介詞。例：Thatgirlhasnothingtoworryabout.那個(gè)女孩沒有什么好擔(dān)心的。③不定式修飾something、anything>nothing時(shí)，放在它們的后面，如果something、anything>nothing有形容詞修飾，詞序是“something/anything/nothing+形容詞+不定式”。例：Ihadsomethingcoldtodrink.我喝冷飲了。（4）不定式作表語動(dòng)詞不定式可以踉在連系動(dòng)詞后作表語，表示主語的具體內(nèi)容、目的等。動(dòng)詞不定式作表語通?？梢愿髡Z進(jìn)行位置互換。例： 2 Mydreamistobe.becomeafamousscientist.我的夢想是成為一名著名的科學(xué)家。（5）不定式作賓語補(bǔ)足語常見的踉帶to的不定式作賓語補(bǔ)足語的（短語）動(dòng)詞persuade、allow、order、teach、ask、want、invite、forbid、wish、encourage>tell、warn、advise、expect、wouldlike例：Motherasksmenottoplaycomputergamesbeforefinishingmyhomework.在我寫完作業(yè)前媽媽不讓我玩電腦游戲。（6）不定式作狀語①作目的狀語常用結(jié)構(gòu)：onlytodo（僅僅為了），inordertodo，soastodo。例：Heranfastsoastocatchthefirstbus.他跑得很快，為的是趕上第一班車。②作結(jié)果狀語常用結(jié)構(gòu)：so...asto，too...to...，enough...to...，onlytodo例：Iawokeonlytofindmyluggagegone.我醒來后發(fā)現(xiàn)我的行李不見了。③作原因狀語例：I,monlytoogladtohavepassedtheexam.考試及格了，我非常高興。（7）不定式用作獨(dú)立成分不定式用作獨(dú)立成分，往往是用作評(píng)注性狀語。Tobehonest,itwasoneoftheworstbooksI,veeverread.說實(shí)話，那是我讀過最差的書之一。拓展：常用作獨(dú)立成分的不定式短語：tobefrank坦率地說、tobehonest老實(shí)說、tobeginwith首先、tostartwith首先、totellyou 3 thetruth說實(shí)話二、使用動(dòng)詞不定式的主要句型.不定式的否定式（1）不定式的否定式為：not+不定式例：Theteachertoldusnottoreadthebook.老師告訴我們不要讀那本書。（2）比較不定式的否定式和否定句的區(qū)別例：Ididn,taskhimtoopenthedoor.我沒讓他把門打開。Iaskedhimnottoopenthedoor.我讓他別把門打開。.疑問詞+不定式不定式可以和疑問代詞who，what，which及疑問副詞when，how，where連用構(gòu)成不定式短語，在句中充當(dāng)主語、賓語、表語等成分。例：Thequestioniswhentostart.問題是什么時(shí)候開始。.too...to...和enoughto...（1）“too+adj./adv.+todosth”意為“太......（以至于）不能......”。例：It,snevertoooldtolearn.活到老學(xué)到老。此句型還可以是：too..forsb./sth.todosth.Theboxistooheavyformetocarry.這個(gè)箱子對(duì)我來說太重了，我搬不動(dòng)。此句型也可以是：so…that+主語+can,t/couldn'tHewastootiredtomoveon.=Hewassotiredthathecouldn,tmoveon.他太累了，不能繼續(xù)走了。（2）“adj./adv.+enoughtodosth”意為“足夠 能做 ”。例：Thegirlisoldenoughtogotoschool.這個(gè)女孩已到上學(xué)的年齡了。此句型也可轉(zhuǎn)換為so...that+主語+can句型。Thegirlissooldthatshecangotoschool..Itbe+adj.of/forsb.+todosth.（1）forsb.句型通常使用表示客觀情況的形容詞，如easy、difficult、hard、important、possible、interesting?？赊D(zhuǎn)化為Todosth.+be+adj.+todosth.例：ItwashardforhimtolearnEnglishwell.=TolearnEnglishwellwashardforhim.對(duì)他來說學(xué)好英語太難了。（2）ofsb.句型一般用表示主觀感情或態(tài)度的形容詞，如good、kind、nice、clever、foolish、right、wrong、careful。可轉(zhuǎn)化為sb.+be+adj.+todosth.例：It,skindofyoutosayso.=Youarekindtosayso.你能這樣說真好。.其他句式1）It,sone,sturntodosth.輪到某人做某事了。2）Ittakes/tooksb.sometimetodosth.某人花多長時(shí)間做某事。3）It,stimetodosth.=It，stimeforsth.是該 的時(shí)候了。4）sb.+be+adj.+todosth.某人因 而 。）find/think/feelit+adj.+todosth.發(fā)現(xiàn)/認(rèn)為/感到做某事是 的。三、動(dòng)詞不定式符號(hào)to的省略.使役動(dòng)詞后省略to的情況在let，make，have等使役動(dòng)詞后用作賓語補(bǔ)足語的不定式必須省略to。例：Shealwaysmakesmelaugh.她總是讓我大笑。.感官動(dòng)詞后用作賓語補(bǔ)足語的不定式必須省略to例： 5 Iwatchedhergetintothecar.我看著她上了車。.動(dòng)詞help后省略to的情況在動(dòng)詞help后用作賓語或賓語補(bǔ)足語的不定式可以不帶to。例：CanIhelp（to）carrythisheavybox？我可以幫忙搬這個(gè)重箱子嗎？.why（not）...后省略to的情況why（not）...之后的不定式不能帶to。例：Whynotasktheteacher？為什么不問問老師？.跟在表示“除.....之外”意義的but，except之后的動(dòng)詞不定式，若but，except之前有實(shí)義動(dòng)詞do的任何形式，通常省略動(dòng)詞不定式符號(hào)to。例：Hismothercoulddonothingbutwaitforthedoctortoarrive.他媽媽除了等著醫(yī)生到來之外別無他法。提示：后跟省略to的不定式作賓語的動(dòng)詞一“感"feel二“聽"hear，listento三“讓”make，let，have四“看"watch，notice，see，lookat“半”幫助help（可省略，亦可不省略）當(dāng)堂練習(xí).——Couldyouteachmehowcakes?---Sorry,Idon'tknow.AmakeBmakingCtomakeDmade2.Ourteachertolduscarefullyinclass.AlistenBtolistenClistenedDlistens
