besidessleep.Ihavesomethingtosay.Hehasalotofhomeworktodo.Heislookingforaroomtolivein.Thereisnothingtoworryabout.(5).定语(如果不定式中的动词是不及物动词,则不定式中要有介词.)不定式作定语时，应放在被修饰词的后面，而且放在其他后置定语之后。1.不定式做定语与所修饰的词之间有三种关系：(1)动宾关系

Ihavealotofworktodo.我有很多工作要做。(2)主谓关系

Heisalwaysthefirsttocome.他总是第一个来。(3)同位关系

Weallhaveachancetogotocollege.我们都有上大学的机会。2.不定式所修饰的名词或代词是不定式动作的地点工具等，即使是及物动词，不定式后面仍须有相应的介词。

3.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.他没钱没地方住。请给我一支写字的笔.Pleasegivemeapentowritewith.4.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：Doyouhaveanythingtosend?你有什么东西要寄吗？（不定式tosend的动作执行者是you）2.Doyouhaveanythingtobesent?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）Icameheretoseeyou.Hegotupearlytocatchthetrain.(6)状语inorderto,soasto,enoughto,onlyto,too….to.,关于小品词to(1).不定式中的动词上文已出现过,下文要省略该动词.eg:Wouldyouliketogowithme?I’dliketo.(2).不定式是tobe结构,be不可省.eg:Wouldyouliketobeateacher?I’dliketobe.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.他不知道说什么。(宾语)Howtosolvetheproblemisveryimportant.如何解决这个问题很重要。(主语)Myquestioniswhentostart.我的问题是什么时候开始。(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?固定句型:hadbetter/hadbest+(not)dosth.最好（不）做某事Why(not)dosth.?…prefertodo/preferdoing…prefer+n./doingA+to+n./doingB…prefer+todoAratherthan(to)doB(1).Theypretendednottoseeus.(2).Hepretendedtobesleeping.(3).Shepretendedtohaveknownitbefore.(一般式表示与谓语的动作同时/几乎/发生在它之后.)(在谓语动词发生的同时,不定式的动作也正在进行)(完成式表示动作发生在谓语动作之前)(4).We’rehappytohavebeenworkingwith
