Step2.叙述概念及结构
不定式是动词的一种非限定形式,由“to+动词原形”构成,没有人称和数的变化,在句中不能独立作谓语.但不定式具有名词、形容词和副词的特征,在句中可以作主语、宾语、宾语补足语、表语、定语、状语等。
1.结构:
todo;(否定)nottodo
二.时态与语态形式
一、不定式所作成分
1.作主语2.作宾语3.作宾语补足语4.作定语5.作状语6.作表语7.作独立成分
8.与疑问词等连用
分述:
(1).不定式作主语时,往往放在谓语之后,用it作形式主语.
•Toseeistobelieve.
•It’simpossibleforhumanstoflylikeabirdnow.
(2).不定式作表语
•Myjobistoprotecttheworld.
•Yourtaskisto_____________.
(3)不定式作宾语

一感:
feel
三使:
let;make;have
二听:
listento;hear
Imadehimdohiswork.------Hewasmadetodohiswork(byme).
不定式用在介词but,except,besides后时,如果这些介词前有行为动词do的
各种形式,那么介词后的不定式不带to,相反则带to.
(1).Shecoulddonothingbutcry.
(2).Ihavenochoicebuttogo.
(3).Whatdoyouliketodobesidessleep.
(5).不定式作定语
Ihavesomethingtosay.
Butmybrotherhasalotofhomework_____.
SoIamlookingforsomeone__________.
1.作定语的不定式如果是不及物动词,或者不定式所修饰的名词或代词是不定式动作的地点工具等,不定式后面须有相应的介词。
Heislookingforaroomtolivein.
2.不定式所修饰的名词如果是time,place或way,不定式后面的介词习惯上要省去。
Hehadnomoneyandnoplacetolive.
3.something,anything,nothing,everything等复合不定代词常用不定式做后置定语。
注意比较:
1)Haveyouanythingtosend?
你有什么东西要寄吗?
(不定式tosend的动作执行者是you)
2)Haveyouanythingtobesent?
你有什么要(我或别人)寄的东西吗?
(不定式tobesent的动作执行者是已被省略的me或someoneelse)
(6)不定式作状语inorderto,soasto,enoughto,onlyto,too….to.,
Igotupearlyto______________.
Icamehereto___________.
(7).独立结构
Totellthetruth,Iamnothappyatthemoment.
tobefrank,tobehonest,totellthetruth
(8).与疑问词等连用
Hedidn’tknow____________.
不定式与疑问词who,which,when,how,what等连用,在句中起名词作用,可充当主语、表语、宾语等。
Hedidn’tknowwhattosay.(宾语)
Howtosolvetheproblemisveryimportant.(主语)Myquestioniswhentostart.(表语)
注意:
在与why连用时,只用于why或whynot开头的简短疑问句中,后面紧跟的动词不定式不带to。
Whynothavearest?
(9)固定句型:
1.hadbetter/hadbest+(not)dosth.最好(不)做某事
2.Why(not)dosth.?
3.…prefertodo/preferdoing
4.…prefer+n./doingA+to+n./doingB
5.…prefer+todoAratherthan(to)doB
6.…wouldrather(not)dosth.
7.…wouldratherdoAthan(do)B
8.…wouldrather+句子(过去式)(虚拟语气)要做……
(10)不定式的省略
(1).不定式中的动词上文已出现过,下文要省略该动词.e.g.:
Wouldyouliketogowithme?
I’dliketo.
(2).不定式是tobe结构,be不可省略.e.g.:
Wouldyouliketobeateacher?
I’dliketobe.
二、不定式的否定结构:
不定式的否定结构多由:
“not+不定式”构成,否定副词not,never,seldom,hardly等要置于to前。
Ex.请告诉你的小孩不要在街上玩耍.
Pleasetellyourchildnottoplayinthestreet.
她检查名字为了不犯错误.
Shecheckedthenamessoasnottomakemistakes.
三、不定式的时态:
(1)一般时表示的动作,有时与谓语动词表示的动作同时发生,有时发生在谓语动词表示的动作之后。
Ex.Heseemstoknowthis.他似乎知道这事。
Ihopetoseeyouagain.我希望再见到你。
(2)完成时表示的动作发生在谓语动词表示的动作之前。
很抱歉给了你这么多麻烦。
Ex.I’msorrytohavegivenyousomuchtrouble.
(3)一般进行时表示的动作正在进行,与谓语动词表示的动作同时发生。
Ex.他好象正在吃什么东西。
Heseemstobeeatingsomething.
