什么是非谓语动词?
在句子中充当除谓语以外的句子成分的动词形式叫做非谓语动词
是动词的非谓语形式.动词一般在句子中充当谓语.在句中可起名词,形容词,副词的作用,在句中充当主语,宾语,表语,补语,定语或状语.即动词的非谓语形式除了不能独立作谓语外,可以承担句子的任何成分
3种形式:不定式,分词(现在分词、过去分词),动名词
不定式
不定式是什么?
有to的,没有 to的,两种。
常用形式:一般主动式to do, 一般被动式to be done完成主动式to have done, 完成被动式to have been done进行式to be doing
注意!不定式和一般的动词一样,有自己的主动和被动。
主动:I am glad to see you.
被动:You are here to be trained as soldiers.
不定式的含义:应当、将要、随之要发生的事
不定式有什么作用?
1.作主语
To master a foreign language is very important.
(It is very important to master a foreign language.)
2.作宾语
Do you want to visit the Great Wall?
3.作宾补(复合宾语)
The teacher advised us to have a rest first.
4.作定语
I have a lot of things to do.
5.作状语
She often comes to see me.
6.作表语
My job is to kill the cockroaches every day.
一、不定式作主语:
A. 直接作主语
Ex:
To see is to believe.
To err is human, to forgive divine.
B. it (形式主语) + be + 形、名 + 不定式
Ex:
It is good to see you.
It is easy to learn English.
It is an honor to meet you.
It is my duty to protect my country.
C. it + V + 宾语 + 不定式(V常用:take,cost,require,make)
Ex:
It takes me 5 minutes to draw the picture.
It costs me 1000 Yuan to buy this machine.
It requires great patience to be a teacher.
D. it (形式主语) + be + 介词短语 + 不定式
Ex:
It is against the law to steal.
It is beyond my ability to do this.
注意:在it作形式主语的句子中,不定式必须带to。
It + be + V-ed+ to do 的句型中,不定式动作与主动作同时发生。
It + be + V-ed+ to have done的句型中,不定式动作发生在主动作之前。
Ex: the boy was seen to fall from the tree.
The boy is said to have fallen from the tree.
二、不定式作宾语
V + 不定式
(V常用:afford、attempt、choose、continue、need、like、love、pretend、promise、 refuse、expect、hope、learn、offer、wish、wait、want、fail、plan、agree、forget、 prefer、decide、manage、try、arrange、determine、desire等)
Ex:
They refused to do my homework.
He pretends to be sleeping.
V + 疑问词(why除外)+ 不定式
(V常用:decide, learn, forget, remember, know, understand, see, think, wonder, find out, settle等)
Ex:
We can’t decide where to go.
I don’t understand what to do.
V + 间宾 + 直宾 (疑问词 + 不定式)
(V常用:teach, inform, tell, show, advise等)
Ex:
I will show you how to use it.
Tell me what to do.
S + V + it (形式主语) + 宾补 + (for sb) +不定式 (真宾语)
(V常用:think, consider, regard, believe, feel, make, find, suppose等)
Ex:
Do you think it difficult to answer the question?
I consider it easy for him to do this.
注意:表希望的动词(过去式)+to+have done,表示本希望完成而没有完成的事情,后面常加上but分句,表遗憾。
Ex:
I __ you off yesterday, but I didn’t have time.
Hope to have seen/ hope to see/ hoped to have seen/ hoped to see
三、不定式作宾补
A. V + 宾 + 宾补(带to的不定式)
(V常用:like, prefer, get, tell, advise, ask, force, expect, encourage, teach, cause, allow, beg, forbid, invite, permit, persuade, remind, want, warn等)
Ex:
He told me to be quiet.
I’d like you to meet Tom.
He advised me to use this machine.
B. V + 宾 + 宾补(省to的不定式)
(V常用:四看:see, watch, notice, observe;三使役:let, make, have; 二听:listen to, hear; 一感觉:feel )
Ex:
I saw him bring out a gun.
I let Tom run.
She had the students do their homework.
C. V + 宾 +(to be)+ 形
(V常用:find, consider, believe, think, feel, prove等)
Ex:
I consider him (to be) cool.
I feel her (to be) very kind.
D. 短语动词 + 宾 + 宾补(带to的不定式)
(短语动词常用:call on, wait for, ask for, depend on, rely on等)
Ex:
We are waiting for you to answer.
Chairman Mao called on us to learn from Lei Feng.
You can’t rely on other people to help you.
注意:a. 宾补不定式的否定形式:not to do。Ex: he warned us not to do it.
b. have + 宾 + do 而 get + 宾 + to do.
四、不定式作定语
形式:被修饰语+to do
不定式与被修饰语的关系:
动宾关系
Ex: I have 2 letters to write.
She has no food to eat.
主谓关系
Ex: he was the only one to have the power.
无主谓动宾关系
Ex: I have no time to do it.
He has no money to buy the book.
注意:a. 由V转化而来的N,且V本身能接to do,那么该N后面常用to do作定语。如:decide/decision, need, order, wish, hope, promise, choose/choice等。
Ex: I have no wish to win. She made a promise to help me.
b. 许多时候to do作定语相当于一个定从的作用。。
Ex: it is the right way to take. = it is the right way that we should take.
c. to do也可以与which连用作定语。
Ex:You must have a sword with which to defend yourself.
You should have the time in which to leave.
d. 带疑问词的to do不能直接作定语。
Ex:This is the only way how to solve the problem. F
e. to do作定语时可以带逻辑主语
Ex:I have a letter for you to read.
五、不定式作表语
不定式作表语,可以用来表达主语的内容,也可以用来表示目的。
主语与表语都是不定式的句型
Ex:To see is to believe.
2. 主语是由V转化而来的N,且原来的V本身接不定式,那么该句的表语也用不定式。
Ex:My wish/hope/plan/purpose is to buy a new car.
3. 主语是由all, what引导的从句,表语可以用不定式。
Ex:All you should do is to apologize.
What she must do now is to keep quiet.
系动词是seem,appear,happen等表似乎、碰巧的单词后,表语用不定式。
Ex:He seems to be ill.
Tom happens to know me.
*在此用法中,主+ seem等动词 + to do = it seems/seemed that 主 do
Ex: she happened to be not at home = it happened that she was not at home.
六、不定式作状语
不定式作状语,修饰动词,在句中表示行为目的、结果、原因。
Be (系V) + 形容词(情绪、状态、品质) + to do
Ex: I am afraid to tell her the truth.
I feel proud to be a Chinese.
He was determined to leave.
You are right to say so.
在固定句型中作状语。
Ex:a. so as to 句型: he was so careless as to leave his door unlocked.
Walk quietly so as not to wake up the baby.
b. in order to句型: He canceled the meeting in order to watch the game.
c. 形 + enough + to 句型: He is old enough to make his own decision.
Are you good enough to close the door for me?
d. too… to…句型: You are too young to understand.
It is too late to go.
e. only to do表示出人意料的结果: We hurried to the classroom only to find none there.
在整个句子中作状语
Ex: To be honest, I like her.
To tell you the truth, I don’t know.
注意现象:a. 不定式的省略。
①and或or连接的并列结构。
Ex: I want to finish my homework and go home.
I’m really puzzled what to think or say.
特例:To be or not to be, this is a question.
He is better to laugh than to cry. (表示对比)
②不定式作表语,前面句中含do时,后面省略to。
Ex:What he did was lose the game.
③介词but、except、besides(除了)、such as,若前面有do,后面要省to,否则就不省。
Ex: what do you like me to do besides swim?
I had no choice but to swim.
④rather than, 前面含有不定式,后面省to。如:I’d like to dance rather than sing.
⑤Why not、had better、would rather、can’t but等词后省to。如:He could not but walk home.
分词
现在分词:V+ing
功能:作定语、状语、表语、宾补。
含义:表主动,同时发生。也表“令人~”
常用形式:一般主动式doing, 一般被动式being done完成主动式having done, 完成被动式having been done
现在分词作定语
Ving + N
Ex: a running horse, a flying pig, a missing child, exciting news, an interesting book.
复合现在分词+N
Ex: a good-looking girl, a hard-working teacher, a record-breaking jump
N+Ving/复合现分: 其功能相当于一个定从
Ex: They plan to build a road leading into (= which lead into) the mountain.
This is a house belonging to (=which belongs to) my dad.
注意:
a. 现分与动名作定语的区别
现分,被修饰N是Ving的主语:A flying bird = a bird that is flying; the sleeping beauty = the beauty who is sleeping.
动名词, N与Ving中没有主谓关系,只表示目的、用途:a waiting room = a room for waiting, 而不是 a room that is waiting.
b. 现分与过分作定语的区别
现分,表示正在的,或,主动的意思。也有“令人~”的意思
过分,表示完成的,或,被动的意思。也有“觉得~”的意思
Ex:比较An eating boy与an eaten apple; Exciting news与excited people.
现在分词作表语
主+系+表(Ving,表情绪、特征、状态)
Ex:The book is interesting.
This movie is boring.
注意:a. 要注意不要把Ving作表语与作进行时搞混。作进行时的V往往表动作。
b. 现分与过分作表语的区别:
现分, 反映本身的属性。“令人~”
过分, 反映人的感觉。“觉得~”
Ex:比较The boy is interesting.与 the boy is interested.
现在分词作状语
1.现在分词在句中作时间、原因、伴随、条件、结果等状语。
①时间状语(前面可加when, while等)
Ex: Hearing the good news, he jumped with great joy.
②原因状语
Ex: Being ill, his father stayed at home.
③伴随状语
Ex: The girls came in, following their parents.
④结果状语
Ex: The poor old man died, leaving nothing to his children.
注意:a. 现分状语的几个特性。①时间性。与谓语动词同时发生to do。发生在主动作之前,用having done。②语态性。③人称一致性。分词的逻辑主语就是句子的主语。
2. 现分作独立主格结构:现分有自己独立的逻辑主语(既,分句和主句各自有自己的主语),名/代+Ving
ex:The day being fine (= as the day is fine), we decide to go to the park.
There being ice on the road, I have to be careful.
比较:Hearing the good news, he jumped with great joy. 前后主语都是he。
3. 作句子的独立状语:
ex: generally/frankly speaking, he is a good man.
现在分词作补语
主+谓+宾+Ving
Ex:I see my teacher coming.
记忆常见动词搭配:see sb doing sth.
hear sb doing sth
watch, smell, catch, find, feel, notice, have, leave, listen to, look at
注意:上述的许多动词既可接do,也可接doing
过去分词:V+ed
功能:作定语、状语、表语、宾补。
含义:表被动,表已经完成(先于谓语发生)。
过去分词作定语
完成或被动的意思
1. Ved + N
Ex: a frightened girl, a broken cup, a missed chance, a satisfied smile;
Fallen leaves, returned students.
复合过去分词+N
Ex: a home-made pie, a well-dressed woman, half-finished products.
N+Ved/复合过分: 其功能相当于一个定从
Ex: There are some thing planned (= which is planned) for tonight.
I always remember the thing happened (= which has happened) 10 years ago.
注意:若要表示正在被进行的动作,则要用过去分词的进行式(既,现分的被动式)
Ex: there is a meeting being held in BJ.
I know nothing about the thing being discussed.
二、过去分词作表语
主+系+Ved(Ved作形容词,要用表情绪、特征、状态的V才可以)
Ex:The boy is interested in this book.
I am disappointed with you.
注意:要注意不要把Ved作表语与被动语态搞混。两者结构相同,意义不同。 Be+表语表状态,被动结构表动作。
比较:The shop is closed. 与The shop is often closed at 9:00.
The window is broken. 与The window was broken by Tom.
三、过去分词作状语
1.句中作时间、原因、条件等状语。
①时间状语(前面可加when, while等)
Ex: When heated (=when it is heated), ice will be changed into water.
②原因状语
Ex: Given an apple (=if the boy is given an apple), the boy will stop crying.
③条件状语
Ex: Given better instruction (=if they are given better…), the students will learn better.
If asked, he will come.
注意:过分与现分作状语的不同。不表伴随,不表结果
2. 过分也有独立主格结构:过分有自己的逻辑主语。名/代+Ved
ex:The work finished (= as the work is finished), we decide to go to the park.
3. 单独的过分作状语:
Ex: frustrated, he went back home.
Astonished, he cried out.
注意几个现象:
a. 过分作状语可以与连词连用: I went on talking, though interrupted by noise.
*b. 少数时候过分被直接当“如果…”用(既不是普通的条件状语,也不是独立主格,此处Ved相当于if):
ex:Given good weather, we will go to the park = if there is good weather…
Provided there is no question, we shall stop today.
四、过去分词作补语
1. 主+谓+宾+Ved 表被动
Ex:I had my shoes repaired yesterday.
I get my dog washed.
The wine made me drunk.
We all wish the problem settled.
How do you like your hair cut?
He found the window broken.
注意:have sb do sth与have sth done的区别
2. 谓 + with + Ved
Ex:The day ended with nothing finished.
He sat with doors closed all day.
动名词
Ving作为名词使用
功能:与普通名词一样:作主、宾、表、同位、以及构成合成词。
常用形式, 与现分一样:(一般主动式doing, 一般被动式being done完成主动式having done, 完成被动式having been done)
1.作主语
普通用法,同一般名词:
Seeing is believing.
Smoking is bad.
Reading helps us learning.
Playing ball is good for the health.
It 作形式主语的用法:
It is no use doing that.
It is no good reading such books.
It is a waste of time going there.
It is worth while discussing the question again.
It is fun playing this game
There be + no +动名 的用法:
There is no knowing what he would do.
There was no arguing with her.
2.作宾语
作动词的宾语: V+动名
Ex: I suggested buying a new car.
Do you enjoy eating?
I can’t help laughing.
什么样的V后要接动名词呢?
作介词的宾语:介+动名
Ex: she left without saying a word.
How about seeing a movie?
作动词短语的宾语
Ex:be devoted to, look forward to, get/be used to, object to doing sth
Prevent sb from doing, have trouble (in) doing, put sb into trouble of doing, insist of doing
3.作表语
主+系+doing(名词性表语)
Ex:My job is teaching.
4.作同位语
与动作性名词相联,作其同位语
Ex:This move, stretching your body, is good for your bone.
His aim, winning the game, is very clear.
