“pkfadongji”通过精心收集，向本站投稿了5篇非谓语动词讲解及练习：独立主格结构 ( Absolute structure)，以下是小编为大家整理后的非谓语动词讲解及练习：独立主格结构 ( Absolute structure)，希望能够帮助到大家。
篇1：非谓语动词讲解及练习：独立主格结构 ( Absolute structure)
1.分词短语作状语时，它的逻辑主语应该是句子的主语。
Eg.) Examining the patient, the doctor wrote down something on paper.
Hit by the arrow, he fell from the horse.
应避免写分词逻辑主语和句子主语不一致的句子。如:
Walking along the road, an accident happened. (×)
Listening to the radio, there was a knock at the door. (×)
Walking along the road, I saw an accident. (√)
Listening to the radio, I heard a knock at the door. (√)
2.但独立主格结构的逻辑主语与句子的主语不是同一个人或事。
独立主格结构－－名词普通格或代词主格+其它成分（形，副，介短，分词和不定式）（它们之间存在着逻辑上的主谓关系）
独立主格在句子中作状语，可以表示时间、原因、条件和方式、伴随。主要用于书面语,表示描述.
eg.) 1.今天是星期天，你不必去上学。
A) 用原因从句表达：
Because it is Sunday, you needn't go to school.
B) 用分词独立结构表达：
It being Sunday, you needn't go to school.
但不能写成：Being Sunday, you needn't go to school.
(因分词的逻辑主语不是句子的主语，所以句子错误。)
2.官员们都到齐了，宣布开会。
A) 用分词独立结构表达：
All the officials having arrived, the meeting was declared open.
B) 用时间状语从句表达：
After (when) all the officials had arrived, the meeting was declared open.
3. 天气允许的话，我们去颐和园。
A) 用分词独立结构表达：
Weather permitting ,we'll go to the Summer Palace.
B) 用条件状语从句表达：
If weather permits , we'll go to the Summer Palace.
4.所有的工作都完成了，你们可以休息了。
All the work done, you can have a rest.
=All the work is done and you can have a rest.
5.他看着这情景，张大着嘴。
He watched the scene, his mouth ( being ) wide open.
6. 会议结束后,他们都回家了。
The meeting (being) over, they all went home. (逻辑谓语是adj./adv 时,前面省略being)
有时,独立主格结构可以由with引出:
eg.) The child trembled, with hands red with cold.
The park is beautiful with all the trees putting on a tender green. 树叶都绿了，使得公园很漂亮。
The road is beautiful, with trees and flowers growing well here and there.
有时, 这种结构中的冠词或物主代词可省去,称为泛指结构,反之,称为特指结构.
Eg.)He came out, umbrella in hand.
=He came out, with an umbrella in his hand.
The guards stood at attention, guns on shoulders.
= The guards stood at attention, with guns on their shoulders.
3.分词固定短语：（有时表示说话人态度的分词结构已成为固定短语，不遵循其逻辑主语和句子主语一致的原则）。
eg.)1.Judging from her accent, she must be an American.
2.Genarally speaking, the living costs are relatively higher in cities.
3.Talking of the world resources , they are very limited.
4.No wonder he was taken ill, considering that he had been overworking for years.
5.Taking as a whole, the experiment was a success.
篇2：英语非谓语动词讲解及练习
非谓语动词是指分词（包括现在分词和过去分词）、不定式、动名词等三种形式，即：
doing , done , to do , doing 。当然它们有各自不同的变化形式，如：
现在分词 doing : 有being done（被动式） ; having done （完成式）; having been do
ne （完成被动式）
不定式 to do : 有to be done （被动式）; to have done （完成式）; to be doing（进行式）
动名词 doing : 有having done（完成式）; being done（被动式） ;
非谓语动词的特点： 三种非谓语动词都具有动词的特征，虽然它们没有人称和数的变化，但是它们都能带自己的状语或有时跟宾语。它们都有各自的特征：分词具有形容词和副词的特征；动名词具有名词的特征；不定式具有名词、形容词和副词的特征。具体来讲：分词在句子中可以做定语、表语、状语或补足语等；动名词在句子中可以做主语、宾语、表语等；不定式在句子中可以做主语、宾语、表语、补足语或状语。
下面分别对三种非谓语动词进行讲解：
一． 动词不定式
先看几个例句，判断不定式在句中的成分。
1．To learn a foreign language is difficult .
2． His wish is to be a driver .
3．Tom wanted to have a cup of beer .
4．The teacher told us to do morning exercises .
5．I have nothing to say .
6．They went to see their aunt .
7．It’s easy to see their aunt.
8．I don’t know what to do next .
9．I heard them make a noise .
说明：1．动词不定式作主语, 2.动词不定式作表语,3.动词不定式作宾语,4．动词不定式作宾语补足语，5．动词不定式作定语,6．动词不定式作目的状语,7．动词不定式作真正主语，it 代替动词不定式，作形式主语。8．带有连接代词的动词不定式作宾语,9．不带to 的动词不定式作宾语补足语。
掌握动词不定式应注意的几个问题：
1． “to” 是不定式符号还是介词，下列短语中的to 都是介词。
agree to object to close to , come to , lead to , refer to ,
equal to , familiar to , point to , thank to , devote to , next to , belong to , be used to , look forward to
2． 带to 还是不带to
I have no choice but to give in
I cannot do anything but give in
I saw him enter the classroom .
（ 但是： He was seen to enter the classroom .）
3． 动词不定式逻辑主语是由for 作为标记的。但是有时用of .
It’s necessary for you to study hard .
It’s foolish of him to do it .
与of 连用的形容词有：
good, kind , nice , wise ,clever , foolish , right , wrong , careful , careless , polite , possible
4．后接不定式作宾语的动词有：
want , hope , wish , like , begin , try , need , forget , agree , know , promise , teach , refuse , help , arrange , dare , decide , determine , fail , manage , offer , prepare , continue , ask , mean , choose , expect etc.
需要宾语补足语的动词不能用动词不定式直接做介词的宾语，而要用it做形式宾语。例如：通常不说We think to obey the laws is important . 而说We think it important to obey the laws .
5．不定式的省略。下列短语中，如果意义明确，常常省略到to 。
want to , wish to ,hope to , like to , hate to , plan to , try to , love to , have to , o
ught to , need to , used to , be able to
6．不定式作定语，应注意两种关系：
1）动宾关系：
He has a lot of meeting to attend .
Please lend me something to write with .
He is looking for a room to live
He is looking for a room to live in .
He has no money and no place
to live ( in ) .
I think the best way to travel ( by ) is on foot .
There is no time to think ( about ) .
2）主谓关系：
She is always the last ( person) to speak at the meeting .
----I’m going to the post office , for I have a letter to post . ( 逻辑主语是I )
-------Thank you. But I have no letters to be posted now ( 逻辑主语不是I )
7．不定式作状语，可以有以下几种意义：
1） 原因
He is lucky to get here on time .
这种结构中常用的形容词有：
happy , glad , delighted , pleased , sorry , eager , anxious . lucky , fortunate , proud , angry surprised , frightened , disappointed , ready , clever , foolish , worthy
2) 目的
He came to help me with my maths .
3) 结果
I hurried to get there only to find him out .
The book is too hard for the boy to read .
He is old enough to go to school .
8 . 不定式作补足语
I saw him play in the street just now .
能跟不带to 的不定式作补足语的动词有：
see , feel , hear , listen to , look at , watch , let , have make, observe, notice
注: 当这些词为被动式时，不定式要带to , 如：
He was seen to play in the street just now.

前者是动名词 ， 后者是现在分词
又如： drinking water , walking stick running water , sleeping boy

例如：His coming made us very happy .
4．动名词的语态和时态

3）常作表语的过去分词：

篇3：非谓语动词讲解及练习：动名词
动 名 词 (The Gerund)
动名词可以起名词的作用，在句中作主语、宾语、表语和定语；同时，它还保留着动词的一些特征，如有完成式和被动语态，可以有自己的宾语和状语.
动名词的形式：以write为例
主动语态 被动语态
一般式 writing being written
完成式 having written having been written
一、动名词的句法功能：
1． 作主语
eg.) Reading books makes one wise.
Collecting stamps is interesting.
① 与不定式区别:
动名词作主语表示经常性、习惯性的抽象动作;不定式作主语表示具体的特别是将来的动作。
Eg.) _____ (Walking, To walk) is a good form of exercise for both young and old.
_____ (Finishing, To finish) the work in a week is impossible.
② 常用it作形式主语:
限于名词: good, use, fun, joy或形容词:good, nice, interesting, useless, worth, etc.
eg.)It’s no use crying over spilt milk.
It’s no good quarrelling with such a bad-tempered person.
③ 注意主谓一致:
单个的动名词短语作主语,谓语用单数;由and连接的多个动名词短语作主语, 谓语多用复数.
Eg.) Plating flowers _____ (need) constant watering.
Learning a theory and putting it into practice ___ (are, is) two different things.
④ 用于结构:
There is no doing sth.
No doing.
have a good (hard ) time/ difficulty/ problem/trouble /fun/ pleasure (in) doing sth.
Eg.) There is no ____ (know) what will happen in the future.
No _____ (spit) in public places.
With the boy _______ (lead) the way, we had no difficulty ________ (find) his house.
2.作表语：(be, remain, taste, sound, smell等link-v.后)
eg.)In the ant city, the queen’s job is laying eggs.
My job is _____(type) letters.
(抽象、习惯性、经常性的动作)
My job now is _______(type) these letters.
(某次具体的特别是将来的动作)
3.作定语：
动名词和现在分词作定语时的区别:
动名词作定语时,表示它所修饰的名词的用途,而不表示动作.现在分词作定语时,表示它所修饰的名词正在进行的动作.
a walking stick= a stick for walking
a dancing hall= a hall for dancing
比较:
a sleeping car= a car for sleeping ( _______ )
a sleeping boy=a boy who is sleeping ( _______ )

篇4：非谓语动词讲解及练习：动词不定式(The Infinitive)
动词不定式(The Infinitive)
动词不定式：（to）+ do，具有名词、形容词、副词的特征。
一、不定式的形式：
主 动 被 动
一般式 to do to be done
进行式 to be doing /
完成式 to have done to have been done
完成进行式 to have been doing /
否定式：not /never + (to) do
二、不定式的句法功能：
1.作主语：
eg.)To make a speech here is an honor.
To lose heart means failure.
动词不定式短语作主语时，常用形式主语it作形式主语，如上两句可用如下形式：
It is an honor to make a speech here.
It means failure to lose heart.
常用结构：
It+be+ adj./n.+ for sb. to do sth.
It+be+ adj. + of sb. to do sth. =sb. be + adj. + to do sth.
(常见形容词:clever, silly, foolish, stupid, wise, kind, rude, impolite, careless, cruel, crazy, etc.)
Eg.)It’s necessary for us to have a good knowledge of English.
It is foolish of you to make such a mistake.=You are foolish to make such a mistake.
2.作表语：
eg.)Her wish is to become a novelist.
He appears to have caught a cold.
不定式一般紧跟在系动词如be, seem, remain, appear等后面,用来说明主语的内容。这类结构中的主语一般为名词，如：idea, purpose, hope, plan, intention, wish, dream, etc.
eg.) My purpose is to teach them a lesson.
有时句子主语也可以是不定式或名词性从句。
Eg.) To be strict with students is to be responsible to them.
What I want to do is (to )tell you the truth.
如果主语中含有do的任何形式, 那么不定式可以省去to.
Eg.) The only thing he could do was ( to) tell the truth.
比较:
A组: Sth.+be +不定式(作表语)---表示主语的具体内容
Sth.+be +不定式(作表语)---表示时态(将来时)
Eg.)He is to tidy up the room.
His plan is to tidy up the room.
B组:动名词和不定式在句中作表语的区别:
1. 一般情况下,区别不大,可通用
eg.) Seeing is believing.
=To see is to believe.
2. 动名词表示的动作较抽象、或是习惯性的, 而不定式表示某次具体的动作.
Eg.)My job is typing papers.
My job now is to type these papers.
3.作宾语：
A. 动词+ to不定式
常见动词: hope, wish, long, want, refuse, pretend, promise, agree, aim, decide, expect, offer, fail, plan, learn, manage, intend, desire, etc.
eg.) I longed to become an artist.
He helped (to) bring up the orphan.
B.动词+(间接宾语)+疑问词+ to不定式
常见动词: know, decide, wonder, learn, remember, understand, find out, etc.

I think it important for you to recite some English articles.
D.介词but, except后可接to不定式作宾语。
注意句中谓语或非谓语部分含有do，那么不定式可省去to
eg.)Seeing the room crowded, I had no choice but to stand in the dark.
Seeing the room crowded, I could do nothing but stand in the dark.
4.作宾语补足语：
A. 动词/动词词组+宾语+to不定式
常见动词: want, wish, ask, tell, order, beg, allow, permit, help, advise, persuade, cause, force, warn, invite, urge, encourage, prepare, call on, would like, wait for, etc.

常用动词: feel (一感) ; hear, listen to(二听); make, let, have(三让); see, watch, observe, notice, look at(五看) ;help (半帮助,可带to或不带to)etc. 但改为被动语态时，不定式要加to.
Eg.) I saw him cross the road.
He was seen to cross the road.
比较: I saw him crossing the road.
He was seen _____the road.
I saw him carried downstairs.
He was seen ____ downstairs.
5.作定语：(考点集中在动词不定式与被修饰词的逻辑关系的判断上)
A.与被修饰名词构成动宾关系：
Eg.) I have a meeting to attend.
He found a good house to live in. (如果不定式是vi，其后应有适当的介词.)
如果不定式修饰time, place, way，可以省略介词：
eg.)He has no place to live.
This is the best way to work out this problem.
注意如果句子的主语不是不定式的逻辑主语,不定式就用被动语态表示。比较:
I am going to the post office, for I have a letter to post.
I am going to the post office, do you have any letter to be posted?
B. 与被修饰名词构成主谓关系：
Eg.)He is the right person to do that job.
He is the first to get here.
注意不定式+介词修饰名词也可以转换成介词+关系代词（whom或which）+不定式。
Eg.) Mary is a nice companion to travel with.
Mary is a nice companion with whom to travel.
I got a piece of paper to write on.
I got a piece of paper on which to write.
C．说明所修饰名词的内容：

Jane expressed a wish to earn her own living.
6.作状语：
A.表目的：
Eg.) He worked day and night to pay off the debt .
She sold her hair to buy the watch chain.
注意不定式逻辑主语与句子主语要一致：
To save money, every means has been tried. (×)
To save money, he has tried every means. (√)
= He has tried every means in order to/so as to save money.
= In order to save money, he has tried every means.
B.表结果：
Eg.)I visited him only to find him out.
Would you be so kind as to tell me the way to the garden Hotel?
His behavior is such as to make his friends angry.
The patient is strong enough to walk about.
too…to…结构
Eg.)It’s too dark for us to see anything.
The question is too simple for him to answer.
注：对少数几个表示心情或倾向的形容词，如：glad, ready, pleased, willing, anxious, happy, satisfied, etc.用于too…to…结构时表示肯定意义。
eg.)They were too anxious to leave.
I am only/but too glad to do you the favor.
C.表原因：
Eg.)They were very excited to hear the news that their team had won the game.
7.作插入语和同位语：
常见插入语:to tell (you) the truth/to be frank; truth to tell实不相瞒;to start/begin with; to conclude; to make matter worse; to be more exact确切地讲;to make a long story short长话短说，简而言之;to be fair公平地说，凭心而论;to be sure肯定地，毫无疑问地;

To make matter worse/___ ____, the computer broke down.
We have made a plan to finish the work.
Her wish to be an air hostess has never come true.
三、不定式的时态:
1.一般式－(to)+动原：不定式的一般式所表示的动作或状态与谓语动词动作同时发生或发生在谓语动词动作之后。
Eg.)The policeman made the thief stand in the corner.
The play is said to be made into a film soon.
2.进行式－to be+现分：不定式的进行式所表示的动作或状态与谓语动词动作同时发生。(seem, appear, happen, pretend等动词的结构中)
Eg.)The boy pretended to be working hard.
=The boy pretended that he was working hard.
He seems to be reading in his study.
=It seems that he is reading in his study.
3.完成式－to have +过分：不定式的完成式表示的动作或状态发生在谓语动词动作之前.
eg.)I regretted to have told a lie.
I happened to have seen the film.
The novel is said to have been translated into several foreign languages.
=It is said that the novel has been translated into several foreign languages.
比较: I must be off now. I am pleased to have met/meeting you all.(分手告别时)
Pleased to meet you, Mr. Cook.(初次见面时)
四、不定式的语态:
主动式和被动式
A. 如不定式的逻辑主语是动作的承受者, 不定式需用被动语态－to be +过分
eg.) He dislikes to be praised in public.
The only animal to be seen in the desert was the camel.
B. 主动的形式表示被动:
①句中存在不定式的逻辑主语, 构成逻辑上的主谓关系：
eg.) The master gave his dog a few bones to eat.
I have a lot of papers to type.
(比较:I am free now. Do you have any papers to be typed?)
②在“形容词+不定式”结构中, 如不定式与句子主语构成逻辑上的动宾关系,那么不定式多用主动语态.
常见形容词：hard, difficult, easy, fit, cheap, expensive, interesting, etc.
Eg.) The water is fit to drink.
The couch is comfortable to sit on.=It is comfortable to sit on the couch.
The sentence is easy _____ (explain). =It is________
The tea is bitter _______(taste).
③在there be结构中,倾向于用不定式主动语态表示被动意义.
Eg.) There is always much work to do in the house.
④下列句子惯用不定式主动语态.
Eg.) The house is to let/to be let. 这房子待出租。
He is not to blame. 他不该受责备。
但在be + to不定式以及be likely to结构中，如果主语是不定式所表示的承受者，那么不定式仍须用被动语态。
Eg.) The collection of poems is to be published within a year.
The results of the exams remain to be seen.
He is likely to be made monitor of our class.=It is likely that he is made ….
五、不定式的否定式： not/never + (to ) 不定式

The boy promised never to play truant again.
六、不定式的省略与保留：保留to,省略do动词。
Ⅰ.不定式符号的省略与保留:
1. 在had better, would rather, would rather…than…, would sooner…than…, cannot but, why (not) 等结构后面的不定式符号to通常被省略。如:

4．在某些感官动词或使役动词（如：hear，listen to， notice，observe， see， watch， make等）之后充当宾语补足语
的不定式中，不定式符号to总是被省略， 但在被动语态的句子中，不定式符号to通常保留。
Eg.) They made that man work all the morning.
That man was made to work all the morning.
5.不定式短语作表语，不定式符号to通常保留，但当what引导的名词性从句作主语，或all，everything等后接定语从句作主语，从句谓语部分含有动词do 或do的其他形式时，作表语的不定式可以保留也可省略不定式符号to。
eg.) The greatest happiness is to work for the happiness of all.
The only thing I can do is (to) go on y myself.
II.不定式符号后面动词的省略与保留
1.为了避免重复，在hope， wish， want， like， love，decide， mean， prefer， have to， be able to， be going to， used to， ought to等动词及习语后面出现与上文相同的不定式时，常保留不定式符号to，而把其它部分省略。
Eg.) Ms King lied to us because she had to.
2.当不定式在ask, advise, persuade, wish, allow, permit, tell, expect, force, invite, beg等动词后面充当宾语补足语时, 为了避免重复, 常保留不定式符号to，而把后面的动词省略.
eg.) She wants to come , but her parents won’t allow her to.
If he doesn’t want to go there, don’t force him to.
He didn’t come, though we had invited him to.
3.在特定的上下文中, 为了避免重复, 如果不定式为一般式to be…或完成式to have done时, 则不定式符号to和be或have常一并保留, be或have之后的部分通常要省略.

--- Hasn’t he finished the report?
--- No, but he ought to have.
补充:
不定式符号后面动词的省略与保留：
Eg.)1. If you don’t want to do it, you don’t need to.
2.---Ought I to finish the work today?
---Yes, you ought to.
注：㈠以上例句中的不定式符号to均不能省略。但如省略名词后的不定式时，则to可以一起省去。
Eg.) Never will Tom miss school for no reason; he hasn’t the courage (to).
I will come as soon as I have got the chance (to).
㈡ want 和would like如用于从句中，to通常可以省略。
Eg.) Come whenever you want (to).

㈣另外两种省略to的情况.
⑴ 如主语部分含有动词do,则作表语的不定式可省略to

⑵当两个或两个以上的不定式并列使用时,除第一个不定式以外,其余的不定式一般要省略to.
Eg.) It is up to you to decide whether to stay or leave.

篇5：非谓语动词讲解及练习：非谓语动词用法对比
非谓语动词的句法功能:
1. 不定式-主、表、宾、补语(宾补&主补)、定、状、同位语
2. 动名词-主、表、宾、定、同位语
3.分 词-表、补语(宾补&主补)、定、状
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。Collecting information about children’s health is his job.
It’s necessary to discuss the problem with an experienced teacher.
2、常用不定式做主语的句型有：
常用结构：It+be+ adj./n.+ for sb. to do sth.
(常见形容词: difficult , important, necessary, impossible, etc.)
It+be+ adj. + of sb. to do sth. =sb. be + adj. + to do sth.
(常见形容词:clever, silly, foolish, stupid, wise, kind, rude, impolite, careless, cruel, crazy, etc.)
3、常用动名词做主语的句型有：It’s no good (use, fun) doing sth.
It’s (a) waste of time one’s doing sth. It’s worth while doing sth.
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。不定式一般紧跟在系动词如: be, seem, remain, appear等后面, 用来说明主语的内容。这类结构中的主语一般为名词，如：idea, purpose, hope, plan, intention, wish, dream, etc.
eg.) My purpose is to teach them a lesson.
有时句子主语也可以是不定式或名词性从句。
Eg.) To be strict with students is to be responsible to them.
What I want to do is (to )tell you the truth.
The only thing he could do was ( to) tell the truth.
如果主语中含有do的任何形式, 那么不定式可以省去to.
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互换，动名词常用于口语中。
Its full-time job is laying eggs.
3、分词做表语:
现在分词作表语:一般表示主动或主语的性质和特征, “令人……”的, 主语多数情况是sth.
过去分词作表语: 一般表示被动或说明主语情感心理上的感受, “感到……的”,主语多数是sb.
exciting, excited annoying, annoyed amazing, amazed
boring, bored confusing, confused encouraging, encouraged
embarrassing, embarrassed frightening, frightened; inspiring, inspired
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）
过去分词作表语表示主语所处的被动状态或完成某动作的状态。而被动语态表示主语所承受的动作。
The village is surrounded by high mountains.（过去分词做表语）
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）
注意: 过分除修饰sb.以外,还可修饰表示神态、声音等的名词, 说明主语的心理状态。
Eg.) He had a _________ (terrifying, terrified) look in his eyes.
The boy answered in a ________ (frightening, frightened) voice.

1、下列动词跟不定式做宾语：
want, wish, hope, expect, ask, demand, pretend, care, decide, happen, long, offer, refuse, fail, plan, prepare, order, cause, afford, beg, manage, agree, promise等。

【lead to, stick to, listen to, refer to, turn to, thanks to, owing to, due to后接名词,一般不接动名词】
3、某些动词后既可接动名词,也可接不定式.
常见动词: begin/start, continue; love, like, dislike, hate, prefer; need, want, require; forget, remember, regret; mean, try, go on, stop, be used to, can’t help
3. begin/start
三种情况下,一般接不定式做宾语:①主语是sth.;②本身用于进行时;③做宾语的动词表示情感、思想或意念时(如:like, love, understand, realize, understand, know, etc.)
A.) love, like, dislike, hate, prefer, 如表示经常性的动作, 用动名词作宾语;如表示特定或具
体的动作,多接不定式.
Eg.) I like___(play) chess during my spare time.

The washing-machine needs repairing.（或用：needs to be repaired）
The point wants referring to.
This English novel is well worth reading.
The situation in Russian required studying.
下列句子惯用不定式主动语态.
Eg.) The house is to let/to be let. 这房子待出租。

四、不定式与分词在句中做宾语补足语：
1、以下动词后跟不定式做宾语补足语：
动词/动词词组+宾语+to不定式:
常见动词: want, wish, ask, tell, order, beg, allow, permit, help, advise, persuade, cause, force, warn, invite, urge, encourage, prepare, call on, would like, wait for, etc.

The doctor advised him to stay in bed for another few days. （注suggest后不跟不定式做宾补。）

常用动词: feel (一感) ; hear, listen to(二听); make, let, have(三让); see, watch, observe, notice, look at(五看) ;help (半帮助,可带to或不带to)etc. 但改为被动语态时，不定式要加to.
Eg.) I saw him cross the road. He was seen to cross the road.

2、下列动词后的复合宾语用分词做宾补：see, watch, notice, observe, find, hear, feel, make, get, set, send, start, catch, have, leave, keep,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。

We have heard the song _____ (sing) in Japanese.
He watched the bed _____ (carry) out of the door.
He felt a great weight _____ (take ) off his mind. 他感到心头如释重负。

五、非谓语动词做定语：
1、不定式做定语放在所修饰的名词后，表示在谓语动词之后发生的动作或过去的某一特定动作。
He had no house to live in but a lot of work to do.
Our monitor is the first to arrive.
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， a stick for walking）
a sleeping car 卧铺车厢（动名词， a car for sleeping）
the rising sun 正在升起的太阳（现在分词）
the changing world 变化中的世界（现在分词）
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。

in the following years =in the years that followed）
a well dressed woman =a woman who is dressed well）
a car parked at the gate =a car which was parked at the gate）

To make himself heard, he raised his voice.（目的状语）
All of us are surprised to see his rapid progress. (原因状语)
2、分词做状语可表示时间、条件、原因、伴随、让步、方式、结果：

动名词的复合结构:
① 物主代词或名词所有格+ 动名词(作主语、宾语、表语)
② 代词宾格或名词普通格+ 动名词(作宾语、表语)
Eg.) My father’s being ill worried us greatly.=That my father was ill worried us greatly.
His not being present at the party annoyed the hostess.
It’s no use your pretending that you didn’t know the truth.
What angered me most was the students failing to fulfill their duties.

eg.) The experiment can’t be carried out because of the equipment being out of order.
The news of the new hotel catching fire shocked everyone.= The news that the new hotel caught fire shocked everyone.
The noises of the boxes being opened and closed could be heard.
存在句的非限定形式
存在句的非限定形式是there to和there being结构。这两种结构在用法上有相同点。为便于比较，我们把它们放在一起介绍。
1） 作介词补足成分
两种结构都可作介词补足成分。如果介词是for，便只能用there to be结构。
Eg.) It is too early for there to be anyone around here.
It is important for there to be a fire escape.
也能用在不及物动词+for之后:
They planned for there to be another meeting.
如果介词不是for, 则要用 there being结构。
Eg.) John was relying on there being another opportunity.
2） 作宾语
作宾语时, 通常用there to be结构。
Eg.) Members like there to be plenty of choice.
能这样用的及物动词为数有限,常见的有expect, mean, intend, want, like, prefer, hate等。
3） 作主语和状语
there being结构还能用作主语和状语。
Eg.) There being a bus stop so near the house is a great advantage.
There having been no rain, the ground was dry.
存在句的限定形式与非限定形式之间可以相互转换。
For there to be so few people in the streets was unusual.
(=It was unusual for there to be so few people in the streets.)
有时限定形式与非限定形式还可以结合使用。
Eg.) It is said that there are troops on the frontier. =There are said to be troops on the frontier.
关系代词的省略:
1. This is the fastest train there is to Beijing.
2. He asks for the latest book there is on the shelf.
3. ---- What did the football player you were talking to want?
---- He would like to read or listen to an account of everything there is going on in the world.
