初中英語八年級下冊非謂語動詞

非謂語動詞期末復(fù)習(xí)概述01非謂語動詞英語中，動詞具有兩種形式：謂語形式和非謂語形式1.動詞的謂語形式必須和主語在人稱和數(shù)上保持一致，受主語的限定，因此又被稱為動詞的限定形式。2.非謂語形式不受主語的限制，因此又被稱為動詞的非限定形式。3.確切地講，非謂語動詞實際上指動詞的非謂語形式。4.非謂語動詞沒有時態(tài)、數(shù)、人稱的變化5.動詞的非謂語形式：（1）不定式：由to+動詞原形構(gòu)成，to為不定式符號，并無實際意義。（2）動名詞：由動詞+ing構(gòu)成。不定式02不定式不定式：tododo否定形式：nottodonotdo不定式做主語Tofinishtheworkintenminutes

isveryhard.用形式主語it代替不定式作主語Itisveryhardtofinishtheworkintenminutes.Itisadj+(forsb)todo....want,hope,wish,like,begin,try,need,forget,agree,know,promise,teach,refuse,help,arrange,dare,decide,determine,fail,manage,offer,prepare,continue,ask,mean,choose,expect等之后跟不定式。例如：（1）IwanttoimprovemyEnglishgrade.（2）用it做形式賓語，如：MarkfounditimportanttostudythesituationinRussia.不定式做賓語want,wish,ask,tell,order,beg,permit,help,advise,persuadeallow,prepare,cause,force,callon,waitfor,invite等詞后做賓補。例如：Iinvitedhersisterstoattendmyparty.不定式做賓語補足語否定形式賓語、賓補的不定式否定一般會前置。IwantnottoimprovemyEnglishgrade.

Idon’twanttoimprovemyEnglishgrade.Iinvitedhersistersnottoattendmyparty.Ididn’tinvitehersisterstoattendmyparty.Heisthefirsttogethere.不定式做定語1、目的狀語Heworkeddayandnighttogetthemoney.Togetthemoney,heworkeddayandnight.2、原因狀語（一般放在adj.之后）I’mgladtoseeyou.3、結(jié)果狀語

(一般和only連用)Ivisitedhimonlytofindhimout.不定式做狀語不帶to的不定式1、不帶to的不定式一般是跟在使役動詞make,let,have...之后。例如：Itmakesmecry.2、放在感官動詞

see,watch,lookat,observe,notice,hear,listento,feel之后的動詞原形，就是不帶to的不定式，強調(diào)動作發(fā)生的事實。例如：Hesawthethiefstealalady’scellphone.動名詞03動名詞動名詞doing否定式notdoing動名詞作主語Readingaloudisveryhelpful.用it做形式主語Itisnogood/use

doingItisawasteoftimedoinghavetrouble/agoodtimedoing

例如：It’sawasteoftimetalkingtohim.enjoy,finish,suggest,imagine,keep,miss,consider,admit,deny,mind,permit,bebusy,beworth,feellike,cantstand,canthelp之后跟動名詞。例如：Theyhaven’tfinishedbuildingthedam.Weenjoyplayingoutside.動名詞作賓語介詞之后的doingby,of,after,before,for,to等介詞之后需跟動名詞。例如：Thanksforhelpingme.IimprovedmyEnglishbyreadingalot.介詞to帶介詞to的短語：lookforwardto,payattentionto,admittodoingbeusedto,sticktodoing....例如：I’mlookingforwardtoreceivingyourletter.易錯點04有些動詞后跟既可以跟todo，也可以跟doing，意義沒有太大的區(qū)別。如：todotodolikecontinuedoingdoingrememberforgettodo記住要做某事doing記得做過某事todo忘記要做某事doing忘記做過某事Remembertobringtheumbrella!（記得要去帶，

還未帶）Idon’tremembertalkingtohim.（記得跟他說過話

）Iforgottogiveyouthebook.（忘記帶書了，

還未帶）Iforgetgivingyouthebook.（忘記帶過書，已經(jīng)帶了）stoptrytodo停下來開始做某事doing停止做某事todo設(shè)法做某事doing嘗試做某事Weneedtostoptofinishourhomework.（停下來手上的事情，再去完成作業(yè)）Weneedtostopplayinggamesnow.（停止玩游戲）Thegovernmenttriestorebuildourcity.（需要付出一定的努力）Itriedcallingyou.（嘗試，并不一定要付出特別大的努力）練習(xí)051.—Mr.Wang,
