二、作表语Myideaistoringhimupatonce.我的想法是马上给他打电话。

如果主语部分含实义动词do，且作表语的动词又是“do”的内容，这时表语不定式的“to”可以省略。如：AllIdidwaswaithere.我能做的就是在这里等。

三、常可接动词不定式作宾语的动词有：agree(同意),hope(希望),decide(决定),need(需要),mean(打算),wish(希望),fail(失败),want(想要),begin(开始),wouldlike(想要)等。Hehasdecidedtogotothecountryside.他已决心去乡下。

四、“疑问词+动词不定式”结构可以作动词know、think、findout等的宾语。Idon’tknowwhotoask.我真不知道该问谁。五、“疑问词+动词不定式”可以作动词show、teach、ask等后面的直接宾语。

Shetoldmewheretofindtheearphone.她告诉我什么地方可以找到耳机。

六、如果宾语太长，可用it作形式宾语，构成“主语+谓语+it+宾语不足语(名词或形容词)+todosth”结构，谓语动词常为find、think、feel等。Ifounditdifficulttostophim.我发现拦截他很困难。

七、动词不定式可以作介词的宾语。

Autumnharvestisabouttostart.秋收即将开始。I’mworryingaboutwhattodonext.我正愁下一步该怎么办。

八、作定语的动词不定式与被修饰词有动宾关系。Ihavealotofbookstoread.我有许多书要读。此时，如果动词定式动词为不及物动词，后面的介词绝对不能省略。Wehadonlyacoldroomtolivein.我们只有寒室一间。

九、作定语的动词不定式与被修饰词有主谓关系。Heisalwaysthefirsttocomeandthelasttoleave.他总是第一个到，最后一个走。十、作定语的动词不定式与被修饰词之间只有修饰关系。Wehavenotimetogototowntoday.今天我们没有时间去城里。十一、作状语的动词不定式常表示目的、原因、方向、结果等。

I’mgladtomeetyou.见到你，我很高兴。Theyranovertowelcometheforeignguests.他们跑过来欢迎外宾。

十二、不定式复合结构“forsbtodosth”可用作主语、表语、定语、状语等。

It’sforhertodecide.这得由她来决定。（表语）Therearemanybooksforyoutoread.这有许多书供你阅读。（定语）Thebookidstoodifficultforchildrentoread.这本书太难了，孩子们看动词不定式

affordaimappearagreearrangeaskbedecidebothercarechoosecomedaredemanddesiredetermineexpectelectendeavorhopefailhappenhelphesitatelearnlongmeanmanageofferoughtplanpreparepretendpromiserefuseseemtendwaitwishundertake2.不带to的不定式结构

以下几种情况使用不带to的动词不定式：

（1）在固定词组hadbetter之后。注意：hadbetter的否定形式是hadbetternotdosth.。如：

Youhadbettergohomenow.你最好现在回家。It’scoldoutside.You’dbetternotgoout.外面很冷，你最好不要出去。

（2）在let,make,see,feel,watch,hear等感官或使役动词后，要跟不带to的动词不定式作宾语补足语。如：

Imadethemgivemethemoneyback.我迫使他们把钱还给我。Ididn’tseeyoucomein.我没看见你进来。

（3）在引导疑问句的whynot之后。Whynot+不带to的不定式是Whydon’tyoudo的省略，可以用来提出建议或劝告。如：Whynotstudywithus为什么不和我们一起学呢Whynottakeaholiday=Whydon’tyoutakeaholiday为什么不休个假呢

（4）不定式动词在介词but,except,besides后面时，如这些介词前有实义动词do的各种形式，则后接不带to的不定式，否则带to。如：Ihavenochoicebuttoacceptthefact.除了接受这个事实我别无选择。Whatdoyouliketodobesidesswim（5）为了避免重复，不定式可省去to。如：I’mreallypuzzledwhattothinkorsay.对于想什么或说什么，我真的很困惑。

二、不定式的时态

不定式常用的时态有一般时、完成时、进行时和完成进行时四种，常用的为前三种。

1.一般时动词不定式的一般式表示不定式的动作或状态与谓语动词所表示的动作同时发生或在之后发生。如：

Iplantoattendthemeeting.我计划参加这次会议。

2.完成时不定式的完成式表示不定式的动作发生在谓语动词表示的动作之前。如：

Iamsorrytohavekeptyouwaiting.很抱歉让你久等了。

3.进行时

不定式的进行式表示不定式的动作与谓语动词所表示的动作同时发生。如：Theyaresaidtobeworkinghard.据说他们工作得很努力。

4.完成进行时不定式的完成进行式表示不定式的动作在谓语动词之前已经发生，并且一直进行着。如：

Heissaidtohavebeenworkinginthatfactoryfortwelveyears.

据说他已在那家工厂工作12年了。

三、动词不定式在句中的作用

1．作主语Toliveistowork.生活就是工作。Tosavetimeistolengthenlife.节约时间就等于延长了人的生命。

不定式结构作主语时，现代英语倾向于采用it作形式主语，而把不定式结构后置的形式。如：

ItisimportantforstudentstostudyEnglish.

学好英语对学生来说是很重要的。

2.作定语（1）不定式作定语，要放在它所修饰的名词或代词的后面。如：Ihavenothingtosayonthisquestion.对这个问题我无可奉告。（2）如果不定式是不及物动词，后面就应有必要的介词。如：Givemeapieceofpapertowriteon.给我一张纸写字。（3）有些名词常可用不定式作定语。如：Ourteacherhadnotimetothinkaboutrest.

我们老师根本没时间考虑休息一下。

3.作宾语a．want，decide，agree等动词后面跟并且只能跟不定式。如：Weagreedtostartearly．Shewantstobeadoctor．b．love，like，begin，start，hate，prefer等词后面可以接不定式。点击规律：上述动词后面除接不定式外，还可以接动名词，意思无很大区别。提示板：likedoing指经常性动作，而liketodo指一次性的动作。如：Ilikeswimming，butIdon'tliketoswimnow．我喜欢游泳，但我现在不想游。c．stop，forget，remember，goon，try等词或短语后面可以接不定式。点击规律：上述动词后面接不定式和接动名词意思大不相同。提示板：1）stoptodosth．：停止一件事，去做另一件事。

stopdoingsth．：停止正在做的事。例句：Whentheteachercamein，thestudentsstoppedtalking；whenhecameout，thestudentsstoppedtotalk．当老师走进来时，学生们停止说话；当老师走出去时，学生们又开始说话。2）思考：forget，remember，goon，try等词或短语后面接不定式和动名词用法有何区别d．在find／feel＋it＋adj．＋todosth．句型中，it是形式宾语，真正的宾语是后面的动词不定式。如：Themandownstairsfounditdifficulttogettosleep．Ifeeliteasytorecitethetext．点击规律：某些动词或短语后面既可以接动词不定式作宾语，又可接动名词作宾语，二者用法上的区别可以通过造句子加以区分，如上面stop例句。Iwishtobeacollegestudent.我希望成为一名大学生。有的及物动词要求跟复合宾语(宾语+宾语补足语)。如果其中的宾语是不定式短语，则必须将形式宾语it放在宾语的位置上，而将不定式短语(真正的宾语)放在宾语补足语之前。如：

IfinditusefultolearnEnglishwell.我发现学好英语很有用。

4.作宾语补足语动词不定式作宾语补足语是动词不定式用法的一个重点，学习时要注意以下三种情况。

（1）作动词ask,like,tell等的宾语补足语时，动词不定式符号to不可以省略。如：

HeaskedmetotalkaboutEnglishstudy.他请我谈谈英语学习。

（2）作使役动词let,have,make以及感官动词feel,hear,see,watch等的宾语补足语时，动词不定式符号to要省略。如：Theteachermadehimsaythewordlikethis.老师让他像这样说这个单词。

（3）作动词help的宾语补足语时，动词不定式符号to可以带，也可以不带。如：

Couldyouhelpme(to)carrytheheavybox你能帮我搬这个重箱子吗？

5.作状语动词不定式及其短语具有副词的特性，可在句中作状语。

（1）作目的状语。如：Hestoppedtohavearest.他停下来休息。

（2）作结果状语。如：Hewokeuptofindeverybodygone.他醒来发现大家都走了。

（3）在某些表示喜、怒、哀、乐等的形容词后作原因状语。如：I’msorrytohearyourgrandmaisill.听到你奶奶生病真遗憾。

（4）在带有enough或too的句子里作状语，表程度。如：Heisoldenoughtogotoschool.他到了上学年龄了。

（5）强调动词不定式所表示的目的时，动词不定式可用inorderto或soasto+动词原形，soasto不用于句首。如：

Thebusstoppedsoastopickuppassengers.公共汽车停下来以便接乘客。1.Don'tforget_________the.tosend
