非谓语动词分为三种形式：不定式、动名词和分词（分词包括现在分词和过去分词）。
非谓语动词没有人称和数的变化，但却有时态和语态的变化。
具体见下表：动词不定式动词不定式是一种非谓语动词形式，其结构为“to ＋动词原形”，其中to 是动词不定式的符号，称为小品词。
动词不定式和其后面的名词等构成不定式短语，在句子中可以用作主语、表语、宾语、补足语、定语、状语等。
一、作主语：动词不定式作主语时，为了避免句子的头重脚轻，可以用“it”作形式主语，而把真正的主语（动词不定式）放在句子的后面。
E.g. To be a doctor is hard. → (It is hard to be a doctor.)To learn English well is not easy. → It is not easy to learn English well. To say is to believe.如果动词不定式的动作是谁做的，可以在动词不定式前面加一个由介词for 引导的短语，称为不定式的复合结构。
若形容词修饰的是人，则需要由介词of 引导短语。
It’s good for us to read E nglish aloud in the morning. It is very kind of you to help me with my English study.二、作表语：在形式上，位于系动词后的就是表语。
从含义上讲，表语是回答主语“是什么”或“怎么样”的语法成分，所以表语也可以视为是主语的补足语。
His work is to drive a car. 他的工作是开车。
To see is to believe.三、作宾语：动词不定式可以放在一些动词后面用作宾语，能以动词不定式作宾语的动词有：begin, start, want, forget, remember, show, learn, like, hate, love, ask 等。

语法复习――非谓语动词(一)动词-ing的用法讲解
语法复习——非谓语动词（一）动词-ing的用法非谓语动词主要包括动词-ing形式、过去分词和不定式。
为了区分这三种不同的非谓语动词的用法和含义，我们将分别从三种非谓语动词在句子中所作的成分以及一些特殊句型等角度来区分其用法和细微含义。
本讲主要阐述动词-ing形式的用法。
动词-ing形式起到名词、形容词和副词的作用，在句中可作主语、宾语和表语、状语和宾语补足语，但不能单独构成谓语。
“动词原形＋ing”构成动词-ing形式可分为动名词和现在分词。

非谓语动词●谓语动词：能直接作谓语的动词叫谓语动词●非谓语动词：不能单独作句子的谓语，不受句子主语的人称和数的限制，而是担任句子其他语法功能的动词，叫非谓语动词。
●非谓语动词有三种：动词不定式，动词现在分词（动名词）和动词过去分词一、动词不定式1. 动词不定式的形成：1）to+doe.g.1. He wants to be a doctor.2. To pass the college entrance exam, we must study hard.3. I have a lot of reading to complete before the end of this term.4. I am sorry to have kept you waiting so long.5. She asked to be sent to work in the countryside.6. He was the only man to have been praised at the meeting.Given enough time, we are sure to do it well.The two men pretended to working hard.2. 不定式的句法功能：在句中不定式可作主语，宾语，宾补，表语，定语，和状语。
1)作主语To make a living in the big city is not easy.为了句子的平衡，避免头重脚轻常采用it作形式主语，而把作真正主语不定式置于句末。
It is not easy to make a living in the big city.It is impossible to buy a car for her young son.= To buy a car for her young son is impossible.2)作宾语不定式做及物动词的宾语。
还有个别介词如：but/except的介词宾语.这些动词有：想决心学会（是有）希望（的），want/expect, decide, learn, hope/wish （先）假装失败，pretend, fail（再）设法拒绝，manage/try, refuse,（然后）主动答应（别人的）计划，offer, promise, plan（最后）同意选择请求别人帮一帮。
agree, choose, ask/beg, helpe.g.1. Right now you need to stay until help comes.2. They don’t want to be too close to one another.3. 不定式在but后时，若but前有实义动词do时，不定式不带to，否则须带to.1) We have nothing to do but _____( wait) for the doctor.2) I have no choice but ________(wait) for the doctor.3) He did nothing all day but _____( practice) reading.4. 如作宾语的动词不定式后面有宾语补足语时，要用it作形式宾语，置于谓语动词后面，而将动词不定式放到宾语补足语后面。
构成; v +it+adj.+ to do 结构They found it hard to learn Chinese.Don’t you think it better to translate it in this way?He felt ____his duty to work for human right and progress.A. whatB. thisC. thatD. it( 能跟it作形式宾语的常见动词有：find /think/ feel/ believe/consider. )3. 作表语不定式作表语用来表示预定要发生的动作，也可用来表示未来的可能性和假设；但不定式所作的表语仅用来说明主语的内容时，这时的不定式只作单纯的表语，而不具有未来的含义。
His dream is to become an actor.Waving one’s hand is to say “Goodbye”.4.作宾语补足语：（1）在有些动词后作宾语补足语，构成v+sb. to do sth.结构。
这些动词有：等待希望和鼓励，wait for /expect/wish/encourage想请求建议和允许，want, beg/ask,advise,allow喜欢命令但依靠说服，like/love, order,depend on, persuade,打算拜访告诉（你有人）邀请，intend, tell, invite, call on宁可教（你）使用强迫（或）禁止（手段）。
prefer,teach, get, forbid（2）动词不定式作感官、使役动词的宾语补足语时，动词不定式不带to，但当句子变为被动语态，作主语补足语时，须带to. 这些动词有;吴（五）看三室（使）两厅（听）一感觉半帮助look at/ see/ watch/ notice/ observemake/ let/ havelisten to/ hearfeelhelp(可以带to也可以不带to)常见的使役动词有四个：have,make,let,get,表示“使、让”的含义。
5. 作定语（1）不定式作定语表示将来的动作。
I have a lot of things to do.The question to be discussed at the meeting is very important.（2）不定式常放在某些名词或代词后作定语。
如果作定语的不定式是不及物动词，或者不定式所修饰的名词或者代词是不定式动作的地点、工具等，不定式后所需要加相应的介词。
I’m not sure which restaurant to eat at.I have no room to live in.He has no pen to write with.（3）不定式用来修饰被序数词、最高级或no，all，any等限定的中心词，且与中心词为逻辑上的主动关系。
He is the best man to do the job.He is always the first to arrive at the school and the last to live the school.（4）被修饰词是抽象名词时，常用不定式作定语。
常见的该类名词有：ability，chance，idea，hope，wish，fact，excuse，promise，attempt，way等。
The ability to express an idea is as important as the idea itself.I have no chance to go sightseeing.[特别注意]不定式作定语时，若句子主语是不定式动作的执行者，则用主动形式表被动含义;若句子主语不是不定式动作的执行者，则用被动形式表被动含义。
She has a sister to look after.(she是look after的执行者)I will go to Beijing. Do you have anything to be bought? （you不是buy的执行者）6.作状语（1）作目的状语，“为了”，可以单独放在句首、句中或句末。
如果强调目的性，不定式前也可加in order或so as，但so as to不能用于句首。

Not having received his answer, I wrote him again.5. Having been told the bad news, he burst into tears.二、v+ing的语法功能:V+ing 可以在句中作主语、宾语、表语、宾补、主补、定语、状语，也可以与be组成谓语。
