动词不定式具有名词、形容词和副词的特征。因此在句中可以做主语、表语、宾语、宾语补足语、定语和状语。
一、不定式做主语：
1、不定式做主语一般表示具体的某次动作。===动名词doing表示习惯的，经常的动作。
e.g:Tofinishthebuildinginamonthisdifficult.
Todosuchthingsisfoolish.
Toseeistobelieve.(对等)
注:1).不定式作主语时,谓语用单数
2).当主语较长，谓语较短时，常用it做形式主语，而将不定式放到谓语的后面。
it做形式主语，不定式放在谓语动词之后常用于下列结构中：
(1)Itis/was+adj.+ofsb.todo…
(2)Itis+adj.+forsb.+todo…
Itiseasy/difficult/hard/foolish/unwise/right/wrong/unnecessary
(3)itis+a+名词+todo...
Itisapity/apleasure/apleasantthing/one’sduty/anhonor/ashame/acrime/noeasyjob…todo
Ittakes(sb.)sometime/courage/patience…todo…
Itrequirescourage/patience/hardwork…todo…
_注意:probable和possible均可作表语，但possible可以用不定式作真实主语，而probable不能用不定式作真实主语。
Itisprobableforhimtocometothemeeting.(错)
Itispossibleforhimtocometothemeeting.
Itispossible/probablethathewillcometothemeeting.
二、不定式做表语
主语是以aimdutyhopeideaintentionplanjobsuggestionwishpurposetask等为中心词的名词词组或以what引导的名词性从句表示，后面的不定式说明其内容,不定式作表语常表示将来或现在的动作或状态。
eg:Myideaistoclimbthemountainfromthenorth.
Yourmistakewasnottowritethatletter.
WhatIwouldsuggestistostartworkatonce.
三、动词不定式作宾语
以不定式结构为宾语的动词有：
ask,agree,care,choose,demand,decide,expect,fail,help,hope,learn,manage,offer,plan,prepare,pretend,promise,refuse,want,wish等只能用动词不定式作宾语
口诀(接不定式作宾语的动词)
想要学习早打算(wantlearnplan)
快准备有希望(preparehopewishexpect)
同意否供选择(agreeofferchoose)
决定了已答应(decidebedeterminedpromise)
尽力去着手做(manageundertake)
别拒绝别假装(refusepretend)
失败不是属于你(fail)
e.g.Tomrefusedtolendmehispen.
Wehopetogettherebeforedark.
Thegirldecidedtodoitherself.

倒装是一种语法手段，用于表示一定的句子结构或强调某一句子成分。倒装句有两种完全倒装和部分倒装。
倒装句之全部倒装
全部倒装是只将句子中的谓语动词全部置于主语之前。此结构通常只用与一般现在时和一般过去时。常见的结构有
1)here,there,now,then,thus等副词置于句首,谓语动词常用be,come,go,lie,run。
Theregoesthebell.
2)表示运动方向的副词或地点状语置于句首，谓语表示运动的动词。
Outrushedamissilefromunderthebomber.
注意上述全部倒装的句型结构的主语必须是名词，如果主语是人称代词则不能完全倒装。
Herehecomes.
