形容词的概念:

形容词(adjective),简称adj.或a,形容词用来修饰名词或代词,表示人或事物的性质、状态,和特征的程度好坏与否,形容词在句中作定语、表语、宾语补足语。通常,可将形容词分成性质形容词和叙述形容词两类,其位置不一定都放在名词前面。


形容词的作用与位置:

形容词是用来修饰名词的,常被放在名词前作定语,或放在系动词后面作表语。以下属几种特殊情况,须牢记;
(1)形容词短语作定语,定语后置。
如:a language difficult to master,
        a leaning tower about 180 feet high
(2)表语形容词(afraid、alike、alone、asleep、awake、alive等)作定语,定语后置。如a man alive。有些表身体健康状况的形容词如well、faint、ill只作表语。sick既可作表语又可作定语,ill如作定语意为“bad”。
(3)用作定语,修饰由不定代词one、no、any、some和every构成的复合词如anything、something等时,通常后置。
如:I have something important to tell you.
(4)else常用作疑问代词和不定代词的后置定语。
(5)enough、nearby修饰名词前置或后置,程度副词一般位于形容词、副词前面,enough修饰形容词、副词时,必须后置。
(6)几个并列的形容词作定语,其语序通常为:限定语(The、A)+描绘性形容词+size(大小)+shape(形状)+age(年龄、时间)+color(颜色)+origin(国籍、来源)+material(材料)+purpose(目的)+名词。

口诀:
限定描绘大长高,形状年龄和新老;颜色国籍跟材料,作用类别往后靠。
如:a heavy black Chinese steel umbrella,
        the man's first tow interesting little red French oil paintings


形容词的用法:

1、形容词修饰名词,说明事物或人的性质或特征。通常,可将形容词分成性质形容词和叙述形容词两类,其位置不一定都放在名词前面:
1)直接说明事物的性质或特征的形容词是性质形容词,它有级的变化,可以用程度副词修饰,在句中可作定语、表语和补语。例如:hot热的。
2)叙述形容词只能作表语,所以又称为表语形容词。这类形容词没有级的变化,也不可用程度副词修饰。
大多数以a开头的形容词都属于这一类。例如:
afraid害怕的。(错)Heisanillman. (对)Themanisill. (错)Sheisanafraidgirl. (对)Thegirlisafraid.
这类词还有:well,unwell,ill,faint,afraid,alike,alive,alone,asleep,awake等。
3)形容词作定语修饰名词时,要放在名词的前边。但是如果形容词修饰以-thing为字尾的词语时,要放在这些词之后。例如:somethingnice

2、用形容词表示类别和整体:
1)某些形容词加上定冠词可以泛指一类人,与谓语动词的复数连接。如:the dead,the living,the rich,the poor,the blind,the hungry The poorarelosinghope.穷人失去了希望。
2)有关国家和民族的形容词加上定冠词指这个民族的整体,与动词的复数连用。如:the British,the English,the French,the Chinese. The English have wonderful senseofhumor.

以-ly结尾的形容词:
1)大部分形容词加-ly可构成副词。但friendly,deadly,lovely,lonely,likely,lively,ugly,brotherly,仍为形容词。改错:
如:(错)She sang lovely.
        (错)He spoke to me very friendly.
        (对)Her singing was lovely.
        (对)He spoke to me in a very friendly way.
2)有些以-ly结尾既为形容词,也为副词。 daily,weekly,monthly,yearly,early .
如:The Times is a daily paper. 
        The Times is published daily.


形容词知识体系:

 


复合形容词的构成

副词的概念:

副词是指在句子中表示行为或状态特征的词,用来修饰动词、形容词、其他副词、介词短语、非谓语动词乃至整个句子,表示时间、地点、程度、方式等概念。


副词的位置:

1)在动词之前。
2)在be动词、助动词之后。
3)多个助动词时,副词一般放在第一个助动词后。
注意:
a. 大多数方式副词位于句尾,但宾语过长,副词可以提前,以使句子平衡。
如:We could see very clearly a strange light ahead of us.
b. 方式副词well,badly糟、坏,hard等只放在句尾。
如:He speaks English well.

副词的排列顺序:

1)时间,地点副词,小单位的在前,大单位在后。
2)方式副词,短的在前,长的在后,并用and或but等连词连接。
如:Please write slowly and carefully.
3)多个不同副词排列:程度+地点+方式+时间副词。
注意:副词very可以修饰形容词,但不能修饰动词。
改错:(错)I very like English.
            (对)I like English very much.
注意:副词enough要放在形容词的后面,形容词enough放在名词前后都可。
如:I don't know him well enough. 
        There is enough food for everyone to eat.
        There is food enough for everyone to eat.


兼有两种形式的副词:

1)close与closely:
      close意思是“近”;closely意思是“仔细地”。
      如: He is sitting close to me.
               Watch him closely.
2)late与lately:
      late意思是"晚";lately意思是“最近” 。
      如:You have come too late. 
              What have you been doing lately?
3)deep与deeply:
      deep意思是“深”,表示空间深度;deeply时常表示感情上的深度,“深深地” 。
      如:He pushed the stick deep into the mud. 
              Even father was deeply moved by the film.
4)high与highly:
      high表示空间高度;highly表示程度,相当于much。
      如:The plane was flying high.
              I think highly of your opinion.
5)wide与widely:
      wide表示空间宽度;widely意思是“广泛地”,“在许多地方”。
      如:He opened the door wide.
              English is widely used in the world.
6)free与freely:
      free的意思是“免费”;freely的意思是“无限制地”。
      如:You can eat free in my restaurant whenever you like. 
              You may speak freely, say what you like.

从属连词的概念:

连词用于引导从句以形成句子的一部分或修饰句子的构成要素的叫作从属连词。


英语从属连词用法分类详解:

从属连词知识体系:

 


用作从属连词的六类名词结构:

英语中有些名词结构可用作从属连词,用以引导状语从句,且主要是时间状语从句。这类结构归纳起来有以下六类:
一、the+瞬间名词:
其中的瞬间名词主要包括moment, minute, instant, second等,其意为“一……就……”,相当于as soon as。
如:The minute he saw her he fell in love. 他对她一见倾心。  
Telephone me the moment(that) you get the results. 你一有结果,马上给我打电话。 
I was so tired that I fell asleep the instant I closed my eyes. 我很累,一合上眼就睡着了。
Sheputdownthereceiverthesecondsherecognizedmyvoice.她一听出是我的声音,马上就放下电话听筒。
注:其中的瞬间名词后可接that,也可省略。另外,有的个别副词(如directly/immediately等)也可表示类似意思。
如: Immediately the meal was over,he switchedon the radio.饭一吃完他就把收音机打开。

二、the+季节名词:
其中的季节名词包括spring,summer,autumn,winter,其意为“在……的那年春天、夏天、秋天、冬天。
如:His wife left him thes pring he went abroad.在他出国的那年春天,他的妻子离开了他。
He sold his house and went to the souththe summer he lost hisjob.在他失业的那年夏天,他卖掉房子去了南方。
He was sentto prison the winter his third daughter was born.在他第三个女儿出生的那年冬天,他被关进了监狱。
She got married the autumn she graduated from college.她大学毕业的那年秋天就结婚了。

三、the+时间名词:
其中的时间名词主要包括hour,day,night,week,month,season,year等,其意为“在……的时候、那天、那个晚上、那周、那个月、那个季节、那年”。
如: The hour he wa sin her office,he felt very sad.当他在她办公室的时候,他感到很伤心。
The day here turned home,his father was already dead.他回家的那一天,他的父亲已经死了。
The night I wenttoseeher,shehadleftforBeijingtoattendanimportantmeeting.就我去看她的那个晚上,她到北京去开一个重要的会议了。
Mr Smith didn't go to work the week his wife was ill.史密斯先生在他妻子生病的那个星期没去上班。
They ear helivedinthecountry,he learned alot.他在乡下呆的那一年,他学到了不少东西。

四、the+序数词+time
其中的序数词包括first,second,third,fourth等,其意为“当第几次……的时候”。
如: My girlfriend beat me at pokert he first time weplayed.我头一次和女朋友打扑克,她就把我赢了。
These cond time I saw her,she looked like an old woman.我第二次见到她时,她看上去像一个老太婆。
The third time I went there,I found all of them had left and the offices were all empty.我第三次去那儿时,我发现他们都离开了,所有的办公室都是空的。
注:
1.next,last也具有类似序数词的性质,因此也具有以上用法。
如: Nexttimeyoucomein,pleaseclosethedoor.下次你进来,请关门。
Thelasttimewetalkedhesaidheneededanothertwodays.上次我们谈话时他说他还需要两天。
2.thefirsttime,thesecondtime,thethirdtime等用作连词引导时间状语从句时,其前通常要有定冠词,而(the)nexttime,(the)lasttime引导状语从句时,其中的冠词可以省略,如下面这道上海高考题,其答案是C,不是A:
I though ther nice and honest______Imether.
A.first time  B.fo rthe first time C.the first timeD.by the first time

五、不定代词+time
其中的不定代词主要包括each,every,any等。
如:Every time I ringher,the phone is engaged.我每次给她打电话,电话都占线。
Every time I see him he either wants to tell me his trouble or borrow some money.每次我见到他,他不是向我诉苦,就是要向我借钱。
He felt nervous each times he spoke to him.每次她和他讲话,他都感到紧张。
AnytimeyoucometoLondondolookmeup.你无论什么时候到伦敦来,一定要来看我。
注意:everytime,eachtime,anytime用作连词引导状语从句时其前习惯上不用冠词,它与the first time,these cond time,the third time等引导时间状语从句时其前必须要用定冠词不同。

六、其他名词结构
以上归纳的名词结构均用于引导时间状语从句,有些其他结构还可引导其他性质的状语从句,如the way可用于引导方式状语从句,表示“像……一样”。如:
The didn’t do it the way we do now.那时他们不像我们现在这样行事。
Joyce looked at me the way alotof girls did.乔伊丝像许多姑娘那样瞧着我。
注:这样用的theway与as用法相似。
如:Hold itin both hands,the way(=as)Mummy does.用两只手捧住,像妈妈那样。


现在分词的被动式概念:

现在分词的被动式表示它的逻辑主语是现在分词动作的承受者。


两种现在分词的被动式:

现在分词的被动式表示它的逻辑主语是现在分词动作的承受者。根据现在分词动作发生的时间,现在分词的被动式有一般被动式(being done)和完成被动式(having been done)。
如:The question being discussed is very important. 正在被讨论的问题很重要。
        Having been criticized by the teacher, he gave up smoking. 被老师批评以后,他把烟戒了。
注意:在need, want, require, beworth等动词(短语)后,作宾语的现在分词常用主动形式来表示被动含义。
如:Your shoes need cleaning.=Your shoes need to be cleaned. 你的鞋需要清洗一下了。
         This book is well worth reading. 这本书很值得一看。


现在分词被动式的用法:

当要表示一个被动动作时,现在分词就用被动形式。现在分词的一般式和完成式均有被动式形式:
(1)现在分词一般式的被动式。
主要表示现在正在进行的动作,也可表示与谓语动作同时发生的动作:
如:Who is the woman being operated on? 正在动手术的女人是谁? 
        I saw him being taken away by the police. 我看见他被警察带走。
【注】有时现在分词一般式的被动式所表示的动作也可发生在谓语动作之前(此时的现在分词通常用于表示原因,且多为状态动词):
如:Not having a car, he finds it difficult to get around. 由于没车,她感到行动很困难。
(2)现在分词完成式的被动式。
主要表示发生在谓语动词之前且已经完成的动作:
如:The subject having been opened, he had to go on with it. 话题已经开始了,他不得不谈下去。
        Having been written in haste, the book has many mistakes. 这书因写得仓促,所以错误不少。
比较:Being soill, she can't go to school. 由于病得那么严重,她不能去上学。
            Having been ill for a long time he needed time to recover. 由于病了很长时间,他需要一段恢复的时间。


现在分词完成式的概念:

从动作关系上看,现在分词的完成式主要表示发生在谓语动作之前的动作;从用法上看,现在分词完成式主要用作状语,表示时间或原因等。


现在分词完成式的基本用法: 
  
1、表示时间:  
如:Having noted down our names and addresses, the policeman dismissed us. 那警察把我们的姓名和地址记下之后就让我们走了。  
        Having found a hotel, we looked for somewhere to have dinner. 在找好旅馆之后,我们就去找吃饭的地方。  
        Having bought our tickets, we went into the theatre. 我们买好票后就走进剧场。  
        Having packed up her things, she went to book her ticket. 她收拾好行李之后就去买车票。  
注:这样用的现在分词通常可以转换成时间状语从句。
如:Having finished her work, she went home. =After she had finished her work, she went home. 她干完工作就回家了。    
2、表示原因:  
如:Having been there once, she knew the place quite well. 由于去过那儿一次,她对那地方很熟悉。  
        Having invited him here to speak, we'd better go to his lecture. 我们邀请他来这儿讲演,所以我们最好去听讲。   
注:这样用的现在分词通常可以转换成原因状语从句。
如:Having been there many times, he offered to be our guide. =As he had been there many times, he offered to be our guide. 他曾多次到过那里,主动提出当我们的向导。  
现在分词的完成式用作状语时,通常位于主句之前,但有时也可置于主句之后,不过此时多见于表原因的场合。
如:I didn't feel terribly shocked, having expected all this. 这情况我早已料到,因此我并不感到过于震惊。  
        I was unable to accept your invitation. having promised to accompany my mother to the concert. 我因已答应陪我母亲赴音乐会而不能接受你的邀请。    

现在分词完成式的否定式:
    
原则上应将not置于整个分词完成式之前。
如:Not having done it right, I tried again. 我由于没有做对,所以又试了试。  
        Not having finished his work, he could not leave the office. 由于工作没干完他不能离开办公室。  
        Not having received an answer, she decided to write him another letter. 由于没得到他的回信,她决定再给他写一封信。       

现在分词完成式用于独立结构:
    
有时现在分词完成式可以用于独立结构。
如:The dark clouds having dispersed, the sun shone again. 乌云已散去,太阳又普照大地了。  
        The river having risen in the night, the crossing was impossible. 夜里河水上涨,渡河不可能了。  
        My turn having comeround, I was ushered into the examining room. 轮到我之后,我就被引入考场。  
        The last bus havingg one, we had to walk home. 最后一班公车已经走了,我们必须走路回家。    

使用现在分词完成式的错点:
    
现在分词的完成式一般不用作定语,遇此情况可改用定语从句。
如:你知道有谁丢了一只猫吗?   
误:Do you know anyone having lost a cat?   
正:Do you know anyone who has lost a cat?   
        我想同打破窗户的人淡淡。  
误:I want to talk to the person having broken the window   
正:I want to talk to the person who has broken the window   
注意:若将以上现在分词的完成式改为一般式也不可以,因为现在分词作后置定语时通常只表示与谓语动作同时或几乎同时发生的动作,而不能先于谓语动作而发生。


现在分词一般式与完成式的区别: 
   
现在分词的一般式和完成式均可表示已完成或先于谓语的动作,但有区别:现在分词一般式所表示的动作虽然可以先于谓语动作,但两者之间没有时间间隔,而现在分同的完成式所表示的先于谓语的动作则与谓语动作有一定的时间间隔。
如:Locking the door, she went out. 她锁上门走了出去。  
        Having lost his job, he'd begun to interest himself in local voluntary work.他失业后便开始关注地方的志愿工作了。  
:有时两者意思差不多,可以换用。
如:Tying one end of the rope to his bed, he threw the other end out of the window.
        Having tied one end of the rope to his bed, he threw the other end out of the window. 他把绳子的一头系在床上,另一头扔出窗外。  
但是注意,用现在分词一般式代替完成式的用法通常只限于现在分词所表示的动作与谓语动词所表示的动作之间没有时间间隔的场合,比如以下情况就不可随便替换。  
1、当换用会引起语义含混时。
如:看完了说明书之后,他迅速拿起了灭火器。  
不妥:Reading the instructions, he snatched up the fireextinguisher.  
正句:Having read the instructions, he snatched up the fireextinguisher.  
前面一句用了现在分词的一般式,给人的印象好像是两个动作同时发生的,容易引起误解,故宜改用完成式。  
2、当两个动作之间有一段间隔时,必须用分词的完成式。
如:Having failed twice, he didn't want to try again. 已经失败了两次,他不想再试了。  
3、当第一个动作持续一段时间时,必须用分词的完成式。
如:Having been his own boss for such a long time, he found it hard to accept orders from another. 自己当老板已经这么久了,他觉得难以听从别人的差遣。    

现在分词完成被动式与过去分词的区别:
    
现在分词的完成被动式有两个特点:一是表示完成,二是表示被动。
如:Having been bitten twice, the postman refused to deliver our letters unless we chained our dog up. 邮递员被狗咬了两次之后要我们把狗拴起来,不然就不给我们送信了。  
过去分词的用法也有两个特点:一是表示完成,二是表示被动。所以有时现在分词的完成被动式与过去分词可以表示相同的意思。
如:(Having been)written in haste, the book has many mistakes. 这书因写得仓促,所以错误不少。  
        (Having been)born in America, he is proficient in English. 由于他是在美国出生的,所以英语很好。  
有时虽然所表示的时间概念相同,但有细微区别:  
如:Having been shown the lab, we left. 被领着看了实验室后,我们就离开了。  
        Shown the lab, we left. 被领着一看完实验室,我们就离开了。(有一种急促感)  
:以下情况通常用过去分词,而不用现在分词的完成式。  
1、过去分词表示先于谓语动同发生的动作外,还可以表示与谓语动词同时(几乎同时)发生的动作,此时不可用现在分词的完成式代替。
如:He came in, followed by his secretary. 他走了进来,后面跟着他的秘书。  
        Convinced that they were going to poison him, he refused to eat anything. 他相信他们要毒死他,所以他拒绝进食。  
2、当过去分词以表示现在或过去(当时)的状态时,也不可用现在分词的完成式代替。
如:The murderer was brought in, his hands tied behind. 凶手被带了进来,双手被绑在后面。  
3、当连用具体明确的过去时间状语时,通常也只用过去分词。
如:Built in1501, the bridge is over 500 years old. 这座桥建于1501年,已有五百多年的历史。    

现在分词的概念:

现在分词(PresentParticiple)(又称-ing形式),是分词的一种,是非限定动词,即在句子里面不能单独充当谓语,但能充当其它的一些成分(定语,表语,补语和状语)。一般式:doing;一般被动式:being done;完成式:having done;完成被动式:having been done。所有否定式都是在-ing前面加not。


现在分词的用法:

1)做表语:
如:He was very amusing.
        That book was rather boring.
很多动词的现在分词都可以作表语:exciting, interesting, encouraging, disappointing, confusing, touching, puzzling.
2)作定语:
上面所出现的现在分词都可以用作定语,修饰一个名词:
如:That must have been a terrifying experience.
        I found him a charming person.
现在分词短语还可以放在名词的后面修饰名词,相当于一个定语从句:
如:There are a few boys swimming in the river.
        There is a car waiting outside.
3)作状语:
现在分词短语可以表示一个同时发生的次要的或伴随的动作:
如:Following Tom, we started to climb the mountain. 
        Opening the drawer, he took out a box.
        Taking a key out of his pocket, he opened the door.
现在分词短语还可以表示原因,相当于一个原因状语从句:
如:Not knowing her address, we couldn't get in touch with her.
        Being unemployed, he hasn't got much money.
现在分词短语还可以表示时间,相当于一个时间状语从句:
如:Hearing the news, they all jumped with joy.
        Returning home, he began to do his homework. 
        Jim hurt his arm while playing tennis.
        Be careful when crossing the road.
        Having found a hotel, we looked for some where to have dinner.
        Having finished her work, she went home.
4)作宾补:
现在分词在一些动词之后可以做宾语的补语:
例如:see, hear, catch, find, keep, have等。
如:I see him passing my house every day.
        I caught him stealing things in that shop.
        I smelt something burning.
        She kept him working all day.


现在分词其他用法解析:

1、现在分词一般式的用法:
现在分词的一般式所表示的动作与主语动作同时发生:
如:When we arrived, we found him sleeping. 我们到达时发现他在睡觉。
         Living in the 示的动作也可略早于或迟于谓语动作,但两者之间没有时间间隔:
如:Seeing nobody at home, he decided to leave a note. 发现没有在家,他决定留个字条。 
         He went home, finding the door locked. 他回到家,发现门是锁着的。当现在分词所表示的动作略迟于谓语动作时,现在分词通常位于句末。

2、现在分词完成式的用法:
现在分词的完成式主要表示发生在谓语动作之前的动作:
如:Having been there once, she knew the place quite well. 由于去过那儿一次,她对那地方很熟悉。
        Having failed twice, he didn't want to try again. 他已经失败了两次,不想再试了。
注:(1)现在分词的一般式和完成式均可表示已完成或先于谓语的动作,但有区别:现在分词所表示的动作虽然可以先于谓语动作,但两者之间没有时间间隔,而现在分词的完成式所表示先于谓语的动作则与谓语动作有一定的时间间隔:
如:Locking the door, he went out. 锁好门之后,他就出去了。
        Having invited him here to speak, we'd better go to his lecture. 既然我们请了他来作报告,我们最好去听一下。
有时即使是分词动作与谓语动作几乎同时发生,但如果要强调分词动作的完成性,也应用现在分词的完成式:
如:Having bought our tickets, we went into the theatre. 我们买好票后就走进剧场。
(2)现在分词的完成式一般不用作定语:
误:Do you know anyone having lost a cat? 你知道有谁丢了一只猫吗?
误:I want to talk to the person having broken the window. 我想同打破窗户的人谈谈。
若将以上现分词的完成式改为一般式也不可以(因为现在分词作后置定语时通常只表示与谓语动作同时或几乎同时发生的动作,而不能先于谓语动作而发生):
误:I want to talk to the person breaking the window.

3、现在分词被动式的用法:
当要表示一个被动动作时,现在分词就用被动形式。现在分词的一般式和完成式均有被动式形式:
(1)现在分词一般式的被动式:主要表示现在正在进行的动作,也可表示与谓语动作同时发生的动作:
如:Who is the woman being operated on? 正在动手术的女人是谁?
         I saw him being taken away by the police. 我看见他被警察带走。
:有时现在分词一般式的被动式所表示的动作也可发生在谓语动作之前(此时的现在分词通常用于表示原因,且多为状态动词):
如:Not having a car, he finds it difficult to get around. 由于没车,她感到行动很困难。
(2)现在分词完成式的被动式:主要表示发生在谓语动词之前且已经完成的动作。
如:The subject having been opened, he had to go on with it. 话题已经开始了,他不得不谈下去。
        Having been written inhaste, the book has many mistakes. 这书因写得仓促,所以错误不少。
比较:Being so ill, she can't go to school. 由于病得那么严重,她不能去上学。
            Having been ill for a long time, he needed time to recover. 由于病了很长时间,他需要一段恢复的时间。


动词不定式的概念:

动词不定式指由to加上动词原形(而且只能是动词原形)所构成的一种非限定性动词,但在有些情况下to可以省略。动词不定式在语法功能上可作主语、宾语、宾语补足语、
表语、定语和状语。


不定式的特殊句型对比:

1、不定式的特殊句型too…to…:
1)too…to 太…以至于…。
例如:He is too excited to speak. 他太激动了,说不出话来。  
        —Can I help you? 需要我帮忙吗?
        —Well, I'm afraid the box is too heavy for you to carryi t, but thank you all the same. 不用了。这箱子太重,恐怕你搬不动。谢谢。
2)如在too前有否定词,则整个句子用否定词表达肯定,too后那个词表达一种委婉含义,意为“不太”。
例如:It's never too late to mend. 改过不嫌晚。(谚语) 
3)当too前面有only, all, but时,意思是:非常…等于very。
例如:I'm only too pleased to be able to help you. 能帮助你我非常高兴。 
            He was but too eager to get home. 他非常想回家。
2、不定式的特殊句型so as to:
1)表示目的:它的否定式是so as not to do。
例如:Tom kept quiet about the accident so as not to lose his job. 汤姆对事故保持沉默是为了不丢掉他的工作。   
            Go in quietly so as not to wake the baby. 轻点进去,别惊醒了婴儿。
2)表示结果:
例如:Would you be so kind as to tell me the time? 劳驾,现在几点了。
3、不定式的特殊句型:Why not:
“Whynot+动词原形”表达向某人提出建议,翻译为:为什么不……?   干吗不……?
例如:Why not take a holiday?


不定式的用法:

1、不定式作补语:
1)有些有动词+宾语+不定式的结构。
例如:advise allow cause challenge command compel drive驱使
enable encourage forbid force impel induce instruct invite like/love order permit make let have want get warn persuade request send tell train urge 等。
例如:Father will not allow us to play on the street. 父亲不让我们在街上玩耍。      
            The officer ordered his men to fire. 长官命令士兵开火。
注意:有些动词如make,have,get,want等可用不定式作做宾补,也可用分词作宾补。现在分词表达主动,也表达正在进行,过去分词表达被动。
2)有些有动词+宾语+不定式的结构,不定式的动词往往是be,不定式一般可以省去。
例如:consider find believe think declare(声称) appoint guess fancy(设想) guess judge imagine know 等。
例如:We believe him to be guilty. 我们相信他是有罪的。 
            We know him to be a fool. 我们知道他是个笨蛋。(tobe不能省去)
典型例题:Charles Babbage is generally considered___the first computer.
                    A. to invent 
                    B. inventing 
                    C. to have invented 
                    D. having invented 
答案:C. 一般没有consider+宾语+be以外不定式的结构,也没有consider+宾语+doing的结构,排除A、B、D。consider用动词be以外的不定式作宾补时,一般要求用不定式的完成式,故选C。 3)有些动词可以跟there+to be的结构。例如:believe expect intend like love mean prefer want wish understand 等。
例如:We didn't expect there to be so many people there. 我们没料到会有那么多人在那里。
            You wouldn't want there to be another war. 你不至于想让另外一场战争发生吧。
2、不定式作主语:
不定式作主语,往往用it作形式主语,真正的主语不定式放至句子的后面。 
例如:It's so nice to hear your voice. 听到你的声音真高兴。
            It's necessary for you to lock the car when you do not use it. 不用车的时候,锁车是有必要的。 
            It's very kind of you to help us. 他帮助我们,他真好。 
            It seemed selfish of him not to give them anything. 他不给他们任何东西,这显得太自私了。
3、不定式作表语:
不定式可放在be动词后面,形成表语。
例如:My work is to clean the room every day. 我的工作是每天清扫房间。  
            His dream is to be a doctor. 他的梦想是成为一名医生。
4、不定式作定语:
不定式做定语通常要放在被修饰的词后,往往表示未发生的动作。
例如:I have a lot of work to do.我有许多事要做。   
            There was nothing to bring home that morning. 那天早上(他回家时)两手空空。
5、不定式作状语:
1)目的状语:常用结构为to do,only to do(仅仅为了), in order to do,so as to do,so(such)...asto…(如此…以便…)。
例如:He ran so fast as to catch the first bus. 他飞快地跑以便赶上第一班车。  
            I come here only to say good-bye to you. 我来仅仅是向你告别。
2)作结果状语,可以表示没有预料到的或事与愿违的结果,不定式要放在句子后面。
例如:I awoke to find my truck gone. 我醒来发现箱子不见了。  
            He searched the room only to find nothing. 他搜索了房间,没发现什么。
3)表原因:
例如:I'm glad to see you.  见到你很高兴。
            She wept to see the sight. 她一看到这情形就哭了。
4)表示理由和条件:
例如:He must be a fool to say so.
            You will do well to speak more carefully.
            You will do well to speak more carefully.


不定式知识体系:

 


不定式用法拓展:

1、用作介词的to:
to可以用作介词,也可用作不定式的标示。下面的to都用作介词:admit to  object to  beaccus to  med to  beused to  stick to  turn to开始 look forward to  be devoted to  pay attention to  contribute to apologize to devote oneself to

2、省去to的动词不定式:
1)情态动词(除ought外)后。
2)使役动词let,have,make后,感官动词see, watch, lookat, notice, observe, hear, listento, smell, feel, find等后。
注意:被动语态中不能省去to。
例如:I saw him dance. 我看见他跳舞。=He was seen to dance.  
           The boss made them work the whole night. 老板让他们整夜干活。 =They were made to work the whole night.
3)would rather,had better句型后:
4)Why…/why not…句型后:
5)help后可带to,也可不带to, help sb(to)do sth:
6)but和except后:
but前是实义动词do时,后面出现的不定式不带to。
比较:He wants to do nothing but go out. 他只想出去玩。  
            He wants to believe anything but to take the medicine. 除了吃这药,他什么都信。
7)由and, or和than连接的两个不定式,第二个to可以省去:
8)通常在discover, imagine, suppose, think等词后作宾补时,可以省去to be。
例如:He is supposed(to be)nice. 他应该是个好人。

3、动词不定式的否定式在不定式标志to前加上not。
例如:Tell him not to shut the window。让他别关窗。 
            She pretended not to see me when I passed by. 我走过的时候,她假装没看见。
4、It's for sb. 和It's of sb. 这样的句子中,由于表语形容词性质的不同,导致了不定式逻辑主语标志用for或of的区别。
1)for sb. 句型中的形容词一般为表示事物的特征特点,表示客观形式的形容词,如easy, hard, difficult, interesting, impossible等:
例如:It's very hard for him to study two languages. 对他来说学两门外语是很难的。
2)of sb句型中的形容词一般为表示性格,品德,心智能力,表示主观感情或态度的形容词,如good, kind, nice, clever, foolish, right。
例如:It's very nice of you to help me. 你来帮助我,你真是太好了。用for还是用of的另一种辨别方法:用介词for或of后面的逻辑主语作句子的主语,用介词前边的形容词作表语,造个句子。如果通顺用of,不通则用for。
例如:You are nice.(通顺,所以应用of)。  
            He is hard.(非所表达的意思,不通,因此用for。)


过去分词的概念:

过去分词一般表示完成和被动的动作,只有一种形式。即:动词原形加-ed构成。
如:fallen leaves 落叶 
        boiled water 开水
        I heard the door closed. 我听见门被关上了。


过去分词与现在分词被动式的区别:

两者均可表示被动,其区别主要在于它们所表示的时间概念不同,但有时它们也可表示相同的意思。
如:Written in haste, the book has many mistakes. 这书因写得仓促,所以错误不少。 
        Being written in haste, the book has many mistakes. 这书因写得仓促,所以错误不少。 
        Having been written in haste, the book has many mistakes. 这书因写得仓促,所以错误不少。
有时虽然所表示的时间概念相同,但有细微区别:
如:Having been show the lab, we left. 被领着看了实验室后,我们就离开了。


过去分词的句法功能:

1、作定语:
如:I don't like the book written by Martin.
       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。 
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:
如:They were very excited at the news. 听到这个消息,他们非常激动。
        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:
如: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:
如: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:
如:Praised by the neighbours, he became the pride of his parents.  受到邻居们的表扬,他成为父母的骄傲。(表示原因)
        Onceseen, it can never be forgotten. 一旦它被看见,人们就忘不了。(表示时间)
        Given more time, I'll be able to do it better. 如果给予更多的时间,我能做得更好。(表示条件) 
        Though told of the danger, he still risked his life to save the boy.  虽然被告之危险,他仍然冒生命危险去救那个孩子。(表示让步) 
        Filled with hopes and fears, he entered the cave. 心中充满了希望与恐惧,他走进山洞。
5、过去分词与逻辑主语构成独立主格:
如:All books returned at the end of the term, the library assistant was satisfied. 所有的书期末时都还了,图书管理员很高兴。
        The field ploughed, he began to spread seed. 地耕好了,他开始撒种子。


现在分词与过去分词的区别:

1、分词作表语:
分词做表语有两种情况,一种是现在分词做表语,一种是过去分词做表语,这两者区别是考试中经常考到的地方。一般来说,表示心理状态的动词如excite,interest等都是及物动词,汉语意思不是“激动”,“高兴”,而是“使激动”、“使高兴”,因而现在分词应该是“令人激动的”、“令人高兴的”,过去分词则是“感到激动的”和“感到高兴的”。所以,凡表示“令人……的”都是-ing形式,凡是表示“感到……”都用-ed形式。换句话说,若人对……感兴趣,就是somebody is in terestedi n...,若人/物本身有兴趣时,就是说sb./sth. is interesting。这类词常见的有:
interesting 使人感到高兴—interested感到高兴的 
exciting令人激动的—excited感到激动的
delighting令人高兴的—delighted感到高兴的 
disappointing令人失望的—disappointed感到失望的
encouraging令人鼓舞的—encouraged感到鼓舞的
pleasing令人愉快的—pleased感到愉快的
puzzling令人费解的—puzzled感到费解的
satisfying令人满意的—satisfied感到满意的
surprising令人惊异的—surprised感到惊异的
worrying令人担心的—worried感到担心的
如:Travelling is interesting but tiring. 旅行是有趣的,但是使人疲劳。
        The pupils will get confused if they are made to learn too much. 如果要学生学得太多,他们会感到糊涂的。 
        The game is exciting. (现在分词作表语)
        We were excited at the news. (过去分词作表语)

2、分词作定语:
分词作定语时有下面几个特点:
1)现在分词表示主动意义,过去分词一般表示被动含意。
2)现在分词表示正在进行,过去分词表示状态或做完(完成)的事。
如:He rushed into the burning house. 他冲进了正在燃烧着的房子。
        The child standing over there is my brother. 站在那儿的男孩子是我弟弟。
        The room facing south is our classroom. 朝南的房间是我们的教室。
        He is an advanced teacher. 他是个先进教师。
3)下列不及物动词也以过去分词形式做定语或表语,但不具有被动意义,这点要注意:
departed, elapsed, faded, fallen, gone, frown-up, retired,  returned, risen, set, vanished, much-traveled, newly-arrived, recently-come

3、分词作状语:
现在分词做状语与过去分词做状语的最主要区别在于两者与所修饰的主语的主动与被动关系的区别。
1)现在分词作状语时,现在分词的动作就是句子主语的动作,它们之间的关系是主动关系。
如:He went out shutting the door behind him. 他出去后将门随手关上。
        Not knowing what to do, he went to his parents for help. 由于不知如何办是好,他去找父母帮忙。
        Smiling, they came in.
2)过去分词作状语时,过去分词表示的动作是句子主语承受的动作,它们之间的关系是被动关系。
如:Cleaned, the room looks nice.
        Given more attention, the trees could have grown better.  如果对这些树多关心一些,它们本来会长得更好。
        Faced with difficulties, we must try to overcome them. 在遇到困难的时候,我们必须设法克服。


一般现在时的被动语态的概念:

表示的是一般现在时态和被动语态的叠合。构成:(am/is/are +done)
如:This shirt is washed once a week. 这件T恤一周洗一次。


主动语态变被动语态的方法:

1、把主动语态的宾语变为被动语态的主语。  
2、把谓语变成被动结构(be+过去分词),根据被动语态句子里的主语的人称和数,以及原来主动语态句子中动词的时态来决定be的形式。  
3、把主动语态中的主语放在介词by之后作宾语,将主格改为宾格。
例如:All the people laughed at him.=He was laughed at by all people.   
            They make the bikes in the factory.=The bikes are made by them in the factory.   
记忆歌诀:
宾变主,主变宾,by短语后面跟。
谓语动词变被动,be后“过分”来使用。  

含有情态动词的被动语态:

含有情态动词的主动句变成被动句时,由“情态动词+be+过去分词”构成,原来带to的情态动词变成被动语态后“to”仍要保留。  
记忆歌诀:
情态动词变动,情态加be加“过分”,原来带to要保留。
例如:We can repair this watch in two days.=This watch can be repaired in two days.   
            You ought to take it away.=It ought to be taken away.   
            They should do it at once.=It should be done at once.

被动语态的用法:
  
1、不知道或没有必要说明动作的执行者是谁。
例如:Some new computers were stolen last night.一些新电脑在昨晚被盗了。(不知道电脑是谁偷的)   
            This book was published in1981.这 本书出版于1981年。  
2、强调动作的承受者,而不强调动作的执行者。
例如:This book was written by him. 这本书是他写的。  
            Eight hours per day for sleep must be guaranteed. 每天8小时睡眠必须得到保证。  
记忆歌诀:
谁做的动作不知道,说出谁做的没有必要;动作承受者需强调,被动语态运用到。


一般现在时的被动语态:

一、被动语态的结构:
主语(动作接受者)+is/am/are+动词的过去分词+(by+动作执行者)
如:Football is played in most countries in the world.
被动语态的句型总结如下:
1、肯定句:主语+be+过去分词+(by~~).
如:The boy is called Jack.
2、否定句:主语+be not+过去分词+(by~~).
如:The baby is not looked after by his father.
3、一般疑问句:Be+主语+过去分词+(by~~)?
如:Is KingLear written by Shakespeare?
4、特殊疑问句:特殊疑词+be+过去分词+(by~~)?
如:What is this kind of sweater made of?

二、被动语态的用法:
1、要表达“被…”、“受…”、“让…”、“遭…”之类的语义。
如:The teachers are well respected. 
        The child is well loved by people.
2、强调动作承受者。
如:He is known far and wide. 他远近闻名。
3、不知道式没有必要指出动作的执行者。
如: The room is cleaned every day. 房子每天都有人打扫。
4、为礼貌起见避免提及动作执行者。
如:I wonder if I was allowed to introduce myself? 我是否可以做自我介绍?


宾语从句的概念:

置于动词、介词等词性后面起宾语作用的从句叫宾语从句。宾语从句的语序必须是陈述语序。谓语动词、介词、动词不定式,v.-ing形式后面都能带宾语从句。有些形容词(afraid, sure, glad等)之后也可以带宾语从句。


宾语从句的用法:

1、宾语从句的引导词:
宾语从句通常由连词that和whether(if)、连接代词或连接副词以及关系代词型what引导:
如:We believe that he is honest. 我们相信他是诚实的。
         I don't know whether he'll arrive in time. 我不知道他是否能及时到。
         I don't know who(m) you mean. 我不知道你指谁。
        He asked why he had to go alone. 他问他为什么必须一个人去。
        Please tell me which you like. 告诉我你喜欢哪一个。
        She has got what she wanted. 她要的东西得到了。
:有时介词后可接跟一个宾语从句(但介词后通常不接that和if引导的宾语从句):
如:From what you say, he is right. 根据你所说的,他是对的。
有极个别介词(如but,except)可接that引导的宾语从句:
如:She remembered nothing about him except that his hair was black. 她对他什么都不记得,只记得他的头发是黑的。
2、宾语从句与形式宾语it:
当宾语从句后跟有宾语补足语时,通常在宾语从句处使用形式宾语it,而将真正的宾语从句移至句末:
如:I think it best that you should stay here. 我认为你最好住这儿。
       He hasn't made it known when he is going to get married. 他还没宣布他何时结婚。
3、连词that的省略问题:
引导宾语从句的连词that通常可以省略:
如:She said(that) she would come to the meeting. 她说过要来开会的。 
        I promise you(that) I will be there. 我答应你我会去。
:有时为了强调,that引导的宾语从句可位于句首,此时that不可省略:
如:That she is a good girl I know. 她是一个好姑娘,我是知道的。
4、宾语从句与否定转移当动词think, believe, suppose, expect, imagine后接一个表示否定意义的宾语从句时,其否定通常转移到主语:
如:I don't suppose that it is true. 我认为那不是真的。
        I don't imagine that he will come. 我想他不会


使用宾语从句特别注意:

一、宾语从句的语序:
宾语从句的语序是陈述句语序即:连接代词/副词+主语+谓语+其他成分。
如:I don't know what they are looking for.
       Could you tell me when the train will leave?
       Can you imagine what kind of man he is?
二、宾语从句的时态:
主句是一般现在时,从句根据实际情况使用任何时态。
句:The headmaster hopes everything goes well.
主句是过去时态,从句须用过去时态的某种形式。
句:She was sorry that she hadn't finished her work on time.
当宾语从句表示的是一个客观真理或者事实时,即使主句是过去时,从句也用一般现在时态。
如:The teacher told his class that light travels faster than sound.
三、宾语从句的特点:
宾语从句可以作及物动词、介词及形容词的宾语。宾语从句的语序一律用陈述句语序。连接词that引导宾语从句在句中无词义,不充当句子成份,多数情况下可以省略。whether和if都可引导宾语从句,但whether后可紧跟or not;whether从句可作介词的宾语。如果从句太长,可以用形式宾语it.
