3种形式:不定式,分词(现在分词、过去分词),动名词
1.非谓语动词与谓语动词的相同点有:

They suggested building a garden.
(2)都可以被状语修饰:
The suit fits him very well.

We have written the composition.(谓语动词的完成时)
Having written the composition, we handed it in.(现在分词的完成式)
(4)都可以有逻辑主语

二、非谓语动词用法:
(一)动词不定式:(to)+do,具有名词、形容词、副词的特征。
1.不定式的形式:(以动词write为例)
否定式:not + (to) do
(1)一般式:不定式的一般式所表示的动作与谓语动词动作同时发生或发生在谓语动词动作之后,
例如:
I'm glad to meet you.
He seems to know a lot.
We plan to pay a visit.
He wants to be an artist.
The patient asked to be operated on at once.
The teacher ordered the work to be done.
(2)进行式:不定式的进行式所表示的动作与谓语动词动作同时发生,例如:
The boy pretended to be working hard.
He seems to be reading in his room.
(3)完成式:不定式的完成式表示的动作发生在谓语动词动作之前,例如:
I regretted to have told a lie.
I happened to have seen the film.
He is pleased to have met his friend.
2.不定式的句法功能:
(1)作主语:
To finish the work in ten minutes is very hard.
To lose your heart means failure.
动词不定式短语作主语时,常用it作形式主语,真正的主语不定式置于句后,例如上面两句可用如下形式:
It is very hard to finish the work in ten minutes.
It means failure to lose your heart.
常用句式有:1、It+be+名词+to do。2、It takes sb.+some time+to do。3、It+be+形容词+of sb +to do。4、It+be+形容词+for sb.+to do。常用careless,,clever,good,foolish,honest,kind,lazy,nice,right,silly,stupid,wise,等表示赞扬或批评的形容词,不定式前的sb.可作其逻辑主语。
(2)作表语:
Her job is to clean the hall.
He appears to have caught a cold.
(3)作宾语:
常与不定式做宾语连用的动词有:want, hope, wish, offer, fail, plan, learn, pretend, refuse, manage, help, agree, promise, prefer, 如果不定式(宾语)后面有宾语补足语,则用it作形式宾语,真正的宾语(不定式)后置,放在宾语补足语后面,例如:
Marx found it important to study the situation in Russia.
动词不定式也可充当介词宾语,如:
I have no choice but to stay here.
He did nothing last Sunday but repair his bike.
动词不定式前有时可与疑问词连用,如:
He gave us some advice on how to learn English.
(4)作宾语补足语:
在复合宾语中,动词不定式可充当宾语补足语,如下动词常跟这种复合宾语:want, wish, ask, tell, order, beg, permit, help, advise, persuade, allow, prepare, cause, force, call on, wait for, invite.
此外,介词有时也与这种复合宾语连用,如:
With a lot of work to do, he didn't go to the cinema.
有些动词如make, let, see, watch, hear, feel, have等与不带有to的不定式连用,但改为被动语态时,不定式要加to, 如:
I saw him cross the road.
He was seen to cross the road.
(5)作定语:
动词不定式作定语,放在所修饰的名词或代词后。与所修饰名词有如下关系:
①动宾关系:
I have a meeting to attend.
注意:不定式为不及物动词时,所修饰的名词如果是地点、工具等,应有必要的介词,如:
He found a good house to live in.
The child has nothing to worry about.
What did you open it with?
如果不定式修饰time, place, way,可以省略介词:
He has no place to live.
This is the best way to work out this problem.
如果不定式所修饰名词是不定式动作承受者,不定式可用主动式也可用被动式:
Have you got anything to send?
Have you got anything to be sent?
②说明所修饰名词的内容:
We have made a plan to finish the work.
③被修饰名词是不定式逻辑主语:
He is the first to get here.
(6)作状语:
①表目的:
He worked day and night to get the money.
She sold her hair to buy the watch chain.
注意不定式放句首时,逻辑主语与句子主语要一致:
wrong:To save money, every means has been tried.
right:To save money, he has tried every means.
wrong:To learn English well, a dictionary is needed.
right:To learn English well, he needs a dictionary.

④表程度:
It's too dark for us to see anything.
The question is simple for him to answer.
(7)作独立成分:
To tell you the truth, I don't like the way he talked.
(8)不定式的省略:保留to省略do动词。
If you don't want to do it, you don't need to.
(9)不定式的并列:第二个不定式可省略to。
He wished to study medicine and become a doctor.
(二)动名词:
动名词既具有动词的一些特征,又具有名词的句法功能。

在蚂蚁王国,蚁后的工作是产卵。
(3)作宾语:

注意动名词既可作动词宾语也可作介词宾语,如上面两个例句。此外,动名词作宾语时,若跟有宾语补足语,则常用形式宾语it,例如:

要记住如下动词及短语只跟动名词作宾语:
enjoy, finish, suggest, avoid(避免), excuse ,delay, imagine, keep, miss, consider, admit(承认),deny(否认), mind, permit, forbid, practise, risk(冒险), appreciate(感激), be busy, be worth, feel like, can't stand, can't help(情不自禁地), think of, dream of, be fond of, prevent…(from),keep …from, stop…(from),protect…from, set about, be engaged in, spend…(in), succeed in, be used to, look forward to, object to, pay attention to, insist on, feel like

1、现在分词的形式:
否定式:not + 现在分词
(1)现在分词的主动语态:现在分词主动语态的一般式表示与谓语动词所表示的动作同时发生,完成
式表示的动作在谓语动词所表示的动作之前发生,常作状语。例如:

2.现在分词的句法功能:

放在名词后。

The man speaking to the teacher is our monitor's father.
正与老师谈话的那个人是我们班长的父亲。
现在分词作定语相当于一个定语从句的句法功能,如:in the following years也可用in the years that followed; the man speaking to the teacher可改为the man who is speaking to the teacher.
(2)现在分词作表语:
The film being shown in the cinema is exciting. 正在这家上演的电影很棒。
The present situation is inspiring. 当前的形势鼓舞人心。
be + doing既可能表示现在进行时,也可能是现在分词做表语,它们的区别在于be + doing表示进行的动作是进行时,而表示特征时是系动词be与现在分词构成系表结构。

所有的票已经卖光了,他们失望地离开了。

⑨作独立成分:
udging from(by) his appearance, he must be an actor.
从外表看,他一定是个演员。
Generally speaking, girls are more careful. 一般说来,女孩子更细心。
(四)过去分词:
过去分词只有一种形式:规则动词由动词原形加词尾-ed构成。不规则动词的过去分词没有统一的规则要求,要一一记住。
过去分词的句法功能:
1.过去分词作定语:
Our class went on an organized trip last Monday. 上周一我们班开展了一次有组织的旅行。
Those elected as committee members will attend the meeting. 当选为委员的人将出席这次会。
注意当过去分词是单词时,一般用于名词前,如果是过去分词短语,就放在名词的后面。过去分词做定语相当于一个被动语态的定语从句。
2.过去分词作表语:
The window is broken. 窗户破了。
They were frightened at the sad sight. 他们对眼前悲惨的景象感到很害怕。
注意:be + 过去分词,如果表示状态是系表结构,如果表示被动的动作是被动语态。区别:
The window is broken.(系表)
The window was broken by the boy.(被动)
有些过去分词是不及物动词构成的,不表示被动,只表示完成。如:
boiled water(开水) fallen leaves(落叶)
newly arrived goods(新到的货) the risen sun(升起的太阳)
the changed world(变了的世界)
这类过去分词有:gone, come, fallen, risen, changed, arrived, returned, passed等。
3.过去分词作宾语补足语:
I heard the song sung several times last week.
上周我听见这首歌被唱了好几次。
有时过去分词做with短语中的宾语补足语:
With the work done, they went out to play. 工作做完了,他们出去玩去了。
4.过去分词作状语:
Praised by the neighbours, he became the pride of his parents.

非谓语动词用法对比
知识要点:
一、不定式与动名词做主语:
1、动名词做主语往往表示普通的、一般的行为,不定式做主语常表示某次具体的行为。例如:
Collecting information about children’s health is his job. 收集有关儿童健康的信息是他的工作。
It’s necessary to discuss the problem with an experienced teacher. 与一位有经验的老师讨论这个问题是有必要的。
2、常用不定式做主语的句型有:

(2)It’s kind (good, friendly, polite, careless, rude, cruel, clever, foolish, brave) of sb. to do.
3、常用动名词做主语的句型有:
It’s no good (use, fun) doing.
It’s (a) waste of time one’s doing.
It’s worth while doing.
二、不定式、动名词、分词做表语:
1、不定式做表语常表示谓语动词所表示动作之后发生的动作。
His teaching aim of this class is to train the students’ speaking ability. 他这节课的教学目的是要训练学生说的能力。
2、动名词做表语是对主语内容的解释,这时主语与表语位置可以互换,动名词常用于口语中。
Its full-time job is laying eggs. 它的(指蚁后)的专职工作是产卵。
3、现在分词做表语表示主语的性质与特征;进行时表示正在进行的动作。
The task of this class is practising the idioms. (现在分词做表语)
With the help of the teacher, the students are practising the idioms. (现在进行时)
4、常用作表语的现在分词有:interesting, amusing, disappointing, missing, puzzling, exciting, inspiring, following等。现在分词表示进行与主动。

The enemy was surrounded by the Red Army.(被动语态)
He is well educated.(过去分词做表语)
He has been educated in this college for three years.(被动语态)
常用在句中做表语的过去分词有:

它们的现在分词常修饰物(有时修饰人),表示主动,过去分词常修饰人,表示被动(包括某人的look、voice等)。例如:
Climbing is tiring. 爬山很累人。
They are very tired. 他们很疲劳
After hearing the exciting news, he gave a speech in an excited voice.
三、不定式与动名词做宾语:
1、下列动词跟不定式做宾语:
want, wish, hope, expect, ask, pretend, care, decide, happen, long, offer, refuse, fail, plan, prepare, order, cause, afford, beg, manage, agree, promise等。

The point wants referring to. 这一点要提到。
This English novel is worth reading. 这本英文小说值得一读。
The situation in Russian required studying. 俄国形式需要研究。

We wish him to remain and accept the post. 我们希望他留下来接受这个职位。(注意hope后不跟不定式做宾补。)
2、有些动词后的复合宾语用不带“to“的不定式,这些动词有:see, watch, notice, hear, feel, make, let, have等。例如:
We noticed him enter the house. 我们留意到他进了那所房子。
The boss made them work twelve hours a day. 老板让他们一天干12小时工作。
注意当make、have不做“迫使、让”讲,而做“制造、有”解时,跟带有to的不定式做状语。
Mother made a cake to celebrate his birthday. 妈妈做了一个蛋糕给他庆贺生日。
He had a meeting to attend. 他有个会要开。
3、下列动词后的复合宾语用分词做宾补:see, watch, notice, observe, hear, feel, make, set, have, leave, keep, find等。用现在分词还是用过去分词做宾补,要看分词与宾语的关系。例:

We have heard the song sung twice. 我们听过这首歌唱过两遍了。

Our monitor is the first to arrive. 我们班长是第一个到的。
2、动名词与现在分词做定语的区别:
动名词做定语说明所修饰名词的用途;现在分词做定语,表示所修饰名词进行的动作。
a walking stick 拐杖(动名词做定语,意为a stick for walking)
a sleeping car 卧铺车厢(动名词做定语,意为a car for sleeping)
the rising sun 正在升起的太阳(现在分词做定语,意为the sun which was rising)
the changing world 变化中的世界(现在分词做定语,意为the world which is changing)
3、现在分词与过去分词做定语的区别:过去分词做定语表示完成或被动的动作,现在分词做定语表示主动或进行的动作。如:
a piece of disappointing news 使人失望的消息(意同a piece of news which disappointed us)
in the following years 在后来的几年中(意同in the years that followed)
a well dressed woman 衣着讲究的女士(意同a woman who is dressed well)
a car parked at the gate 停在门口的小汽车(意同a car which was parked at the gate)
六、不定式与分词做状语:

1.动名词和动词不定式在用法上的比较
1一般说来动名词所表示的动作在意义上是比较抽象的、一般的,时间概念不强,不是指某一次的动作;而动词不定式所表示的动作则往往是具体的一次行为。例如:
1I like swimming, but I don’t like to swim today.
2 They prefer staying indoors when the weather is cold.
3 Would you prefer to stay at home this evening?
2动词不定式的逻辑主语,常常是句子的主语或句中的某个词;而动名词的逻辑主语可能是句子主语或句中某个词,也可能是泛指一般人物,在句子里是找不着的。例如:
1I hate to be sitting idle. 我不想闲坐着。指自己
2I hate saying nothing at a meeting but gossiping afterwards. 我不喜欢开会不说会后乱说。可能指自己,也可能泛指一般人
3有些词后既可接动名词亦可接动词不定式,但意义不同,如stop, remember, forget, neglect, omit, dislike, detests, begin, continue, start, regret, intend, attempt, propose等。例如:
When the teacher came in, the students stopped talking. talking 是宾语,指停止讲话这个动作
When the teacher came in, the students stopped to talk. to talk是目的状语,指停下前一动作来进行talk
Remember, forget doing something 指已做过的事
Remember, forget to do something 指未做过的事
2.动名词和现在分词在用法上的区别
1作定语的区别。分词往往表示它所修饰的词所做的动作,即逻辑主语是它所修饰的词;动名词往往表示与它所修饰的词有关的动作,即所修饰的词不能充当逻辑主语。例如:
sleeping car = a car for sleeping 动名词
working method = method of working动名词
the raging storm = the storm that is raging 狂暴的风雨分词
scorching heat = heat that is scorching 炙人的热气分词
2作表语的区别。分词作表语时保持它的形容词特征,动名词作表语时保持它的名词特征。动名词作表语时常可与主语互换位置,分词则不行。例如:
The novel is interesting. 现在分词
My job is teaching English. 动名词
3作状语的区别。分词具有副词特征,可以直接用作状语;动名词不具有副词特征,不能单独作状语,只有与介词结合时才能作状语。例如:
1 Hearing the news, they immediately set off for the station. 分词作状语
2 Given another chance, I’ll do it much better. 分词作状语
3 After finishing his homework, he went to the reading-room. 动名词与介词一起作状语
4 On ing in she laid a file of documents upon the table. 动名词与介词一起作状语
3.动词不定式作宾语补语和现在分词作宾语补语的区别
动词不定式只说明宾语的一个动作,而分词则说明宾语的动作正在进行。例如:
1Just then he heard someone sing in the next room. 在那时,他听见有人在隔壁房间里唱歌。
2Just then he heard someone singing in the next room. 在那时,他听见有人正在隔壁房间里唱歌。 --------------------------------------------------------------------------------------
