高中英語-Unit1《Living-well》課件-動詞不定式-新人教選修7

動詞不定式不定式由“to+動詞原形”構成,其否定形式是“not/nevertodo”,不定式可以帶賓語或狀語構成不定式短語,沒有人稱和數的變化,但有時態(tài)和語態(tài)的變化。不定式可以作主語、賓語、狀語、表語和定語，但不能單獨作謂語。不定式的邏輯主語有時用“for+名詞或代詞賓格”構成。不定式結構

hear一感覺:

feelwarn,tell,allow,help,ask,force等e.g.Imadehimdohiswork.Hewasmadetodohiswork(byme).注意1>help后面的“to”可省去e.g.Theyoftenhelpthegrandma(to)carrywater.2>see,hear,watch,feel,notice,lookat等表示感覺和let,make,have等表示使役的動詞后面，不定式作賓語時要省“to”（注：被動語態(tài)不省to）3>不定式用在介詞but,except,besides后時,如果這些介詞前有行為動詞do的各種形式,那么介詞后的不定式不帶to,相反則帶to.(1).Shecoulddonothingbutcry.(2).Ihavenochoicebuttogo.(3).Whatdoyouliketodo

besidessleep.Ihavesomethingtosay.Hehasalotofhomeworktodo.Heislookingforaroomtolivein.Thereisnothingtoworryabout.(5).定語(如果不定式中的動詞是不及物動詞,則不定式中要有介詞.)請給我一支寫字的筆.Pleasegivemeapentowritewith.不定式作定語時，應放在被修飾詞的后面，而且放在其他后置定語之后。1.不定式做定語與所修飾的詞之間有三種關系：(1)動賓關系

Ihavealotofworktodo.我有很多工作要做。(2)主謂關系

Heisalwaysthefirsttocome.他總是第一個來。(3)同位關系

Weallhaveachancetogotocollege.我們都有上大學的機會。2.作定語的不定式如果是不及物動詞，或者不定式所修飾的名詞或代詞是不定式動作的地點工具等，不定式后面須有相應的介詞。3.不定式所修飾的名詞如果是time,place或way，不定式后面的介詞習慣上要省去。e.g.Heislookingforaroomtolivein.他在找一個房間住。e.g.Hehadnomoneyandnoplacetolive.他沒錢沒地方住。4.something,anything,nothing,everything等復合不定代詞常用不定式做后置定語。e.g.Doyouhaveanythingtosend?你有什么東西要寄嗎Icameheretoseeyou.Hegotupearlytocatchthetrain.(6)狀語（表示目的,結果,原因）inorderto,

soasto,enoughto,onlyto,too….to.,在一些短語中也有體現(xiàn)不定式作原因狀語

不定式作原因狀語主要用于表示表情與心理狀態(tài)的動詞或表語形容詞；表示人對某事某物的反應如何，有一種直覺感，常譯作“因……而……”的說法。

常見的這類表情心態(tài)形容詞有（be）glad,happy,sorry,sad,worried,pleased,satisfied,surprised,shocked,terrified,frightened,disappointed等。如:Themanshudderedtoseetheterrifyingscene看見這恐怖的場面這個人渾身發(fā)抖。(因為看到了這恐怖場面,這人才渾身發(fā)抖.)(7).獨立結構tobefrank,tobehonest,Totellthetruth,Idon’tagreewithyou.類似的結構(8)不定式與疑問詞who,which,when,how,what等連用，在句中起名詞作用，可充當主語、表語、賓語等。Hedidn’tknowwhattosay.他不知道說什么。(賓語)Howtosolvetheproblemisveryimportant.如何解決這個問題很重要。(主語)Myquestioniswhentostart.我的問題是什么時候開始。(表語)注意：在與why連用時，只用于why或whynot開頭的簡短疑問句中，后面緊跟的動詞不定式不帶to。

Whynothavearest?關于不定式中的小品詞to(1).不定式中的動詞上文已出現(xiàn)過,下文要省略該動詞.eg:Wouldyouliketogowithme?I’dliketo.(2).不定式是tobe結構,be不可省.eg:Wouldyouliketobeateacher?I’dliketobe.exerciseMyteacherwasmade_____histeachingbecauseofpoorhealth.givingupB.togiveupC.giveupD.givenup2.Thesentencewants____oncemore.explainedB.toexplainC.beingexplainedD.explaining3.TheArcticisconsidered____thenorthernpartoftheAtlantic.havingbeenB.tohavebeenC.tobeD.beingBDC4.TheEmperororderedthewonderfulcloth_____forhimwithoutdelay.tohavewovenB.tobewovenC.tobeweavingD.toweave5.IfoundtheGermanlanguagehard____.learnedB.learningC.tobelearnedD.tolearn6.—Thelightintheofficeisstillon.---Oh,Iforgot______.turningitoffB.turnitoffC.toturnitoffD.havingturneditoffBDC幾對易混淆的詞組：stoptodosth.停止去做某事
