高中英语语法讲解不定式
(The Infin itive )
定义：动词不定式是非谓语动词的一种，它没有人称和数的变化，在句子中不能独立作谓语，
但它仍保持动词的特点，既可以有自己的宾语和状语。 E.g. He want his students to read the book aloud.
A.
1
2
不定式的一般式(to do )
一般式表示的动作或状态，发生在谓语动词表示的动作或状态的同时或之后
My wish is to become a doctor
He seemed to be tired.
She stopped to have a rest.
不定式的被动式(to be don e)
当不定式的逻辑主语是这个不定式所表示的动作的承受者时，不定式一般要用被动式.
The build ing to be fini shed n ext mo nth is for our teachers.
I am going to Beijing, I have something to take to my parents, do you have something
to be take n to your pare nts?
如果谓语表示的动作(情况)发生时，不定式表示动作正在进行,这时候不定式就要用进行式. (to be doing )
They are said to be buildi ng ano ther bridge across the street.
They seemed to be talki ng about someth ing importa nt.
When I went to his home, he happe ned to be traveli ng around the world.
I ' m glad to be working with you.
如果不定式所表示的动作或状态发生在谓语动词所表示动作或状态之前，就用完成式(to have done);若是在此基础上的被动含义，就用完成被动式(to have been done).
He is said to have written a novel about the Long March.
He thought it a pity not to have in vited us.
The assista nt seemed to have bee n fired.
He is said to have bee n taught French whe n he was a child.
Ein ste in is said to have built up his theory whe n he was in his twen ties.
如果不定式的动作是在谓语所表示的时间之前一直在进行的动作，就要用完成进行式They are said to have bee n collecti ng folk song in Xinjia ng.
We re happy to have bee n worki ng with the experts all the mon th.
B.用法：
动词不定式具有名词、形容词和副词的特征。因此在句中可以做主语、表语、宾语、宾语补足语、定语和状语。
一、不定式做主语：
1、不定式做主语一般表示具体的某次动作。===动名词doing表示习惯的，经常的动作。
e.g: To finish the build ing in a month is difficult.
To do such things is foolish.
To see is to believe.( 对等)
注:1). 不定式作主语时，谓语用单数
2) .当主语较长，谓语较短时，常用it做形式主语，而将不定式放到谓语的后面。
it做形式主语，不定式放在谓语动词之后常用于下列结构中：
(1) lt is/was +adj.+of sb. to do …
(2) It is +adj.+for sb.+to do …
It is easy / difficult / hard / foolish / un wise / right / wrong / unn ecessary
⑶ it is +a + 名词+ to do...
It is a pity / a pleasure / a pleasant thing / one ' s duty / an honor / a shame
/ a crime / no easy job …to do
It takes (sb.) some time / courage / patienee …to do …
It requires courage / patienee / hard work …to do …
*注意：probable 和possible 均可作表语，但possible 可以用不定式作真实主语，而probable不能用不定式作真实主语。
It is probable for him to come to the meeti ng.( 错)
It is possible for him to come to the meet ing.
It is possible / probable that he will come to the meet ing.
二、不定式做表语
主语是以aim duty hope idea intention plan job suggestion wish purpose
task等为中心词的名词词组或以what引导的名词性从句表示，后面的不定式说明其内容，不定式作表语常表示将来或现在的动作或状态。
eg My idea is to climb the mountain from the n orth.
Your mistake was not to write that letter.
What I would suggest is to start work at on ce.
三动词不定式作宾语
以不定式结构为宾语的动词有：
ask, agree, care, choose, dema nd, decide, expect, fail, help, hope, lear n, man age, offer, pla n, prepare, prete nd, promise, refuse, want, wish 等只能用动词不定式作宾语
口诀(接不定式作宾语的动词)
想要学习早打算(want learn plan )
快准备有希望(prepare hope wish expect )
同意否供选择(agree offer choose )
决定了已答应(decide be determined promise )
尽力去着手做(man age un dertake )
别拒绝别假装(refuse pretend )
失败不是属于你(fail )
e.g.Tom refused to lend me his pen.
We hope to get there before dark.
The girl decided to do it herself.
* 注意: 某些及物动词可用-ing 也可用动词不定式作宾语但意义不同的有stop go on remember forget regret try mean can' t help
be used to
四．动词不定式做定语
1．. 不定式作定语需要后置。
2. 作定语的不定式与被修饰的名词或代词存在着两种主要的逻辑关系，即被修饰的名词和代词是不定式的逻辑主语（逻辑上的主谓关系）或逻辑宾语（逻辑上的动宾关系）
1）不定式前的名词是它的逻辑主语。
He is the doctor to do the operation.
2）不定式和它所修饰的名词是逻辑上的动宾关系。
I have a lot of things to do.
3）不定式前的名词是它修饰的对象。
This is the right time to start.
注意．如果不定式所修饰的词是way 或place, 介词可省略。
He has no way to go （by）. This is the best place to work （at）
五．宾语补足语
He want you to be his assistant. I saw her cross the street.
[ 注1] 如果谓语动词为感官动词或使役动词，则作宾补的不定式不可带to ，这些动词有see, hear, feel, watch, notice; have, make, let 等。
I felt my blood run cold. What made you think like that? 但如果句子是被动语态，则to 不可省略。
He was made to clean the windows as a punishment.
Someone was heard to come up the stairs.
[ 注2] 1. 谓语动词help 后可接带to 或不带to 的不定式作宾补。用不带to 的不定式表示帮助者直接参与动作；用带to 的不定式表示主语没有直接参与动作。
They helped me carry the boxes.
This kind of soap will help you to wash the clothes more easily.
2. 在美式英语或非正式文体中，help 后用作宾补的不定式均不带to 。
3. help 后可以直接用带to 或不带to 的不定式作宾语。
They helped （to） carry the furniture upstairs.
[ 注3]look at 及listen to 后用作宾补的不定式不带to （这主要是美式英语）。
We have been listening to the radio tell a long story.
六．表语补足语当不定式与主语存在逻辑上动宾关系的时候，用主动表被动。
That is hard to say. The chair is comfortable to sit in.
七．不定式做状语不定式做状语修饰动词、形容词、副词等，表示目的、原因、结果、条件等。
1、表目的
e.g. To learn a foreign language well, you must try your best （主语一致） He came here to attend an
important meeting.
He came here in order to see Charlie.
I turned the radio down so as not to disturb him
注：表示目的的不定式可以置于句首，这也是区别于其他功能的标志之一。
*但是，置于句首表示目的的不定式可以是to, in order to ，但却不可以是so as to. ” , ”
To draw maps properly, you n eed a special pen.
In order to draw maps properly, you n eed a special pen.
To get the best results, use clea n water.
To be elected mon itor of our class, he gave money to us.
*放在句末时，to do 表示目的，不可有“，”若有用doing表示伴随的目的
e.g. He bowed to us to tha nk us for help ing him find the way.
He worked day and ni ght, hop ing to finish the work beforeha nd.
注：1.不定式结构表示目的时，通常句子的主语就是它的逻辑主语(主语一致)
e.g.He bought a bicycle to go to tow n more quickly.
He went home to see his mother.
例夕卜 e g He opened the door for the children to come in.
They sent a man to mend the wi ndow.
2、表结果
不定式结构表示结果更常见于下列句型
①so…as to …
Would you be so kind as to lend me your bicycle / tell me the time?
②such (…)as to …
I ' m not such a fool as to believe th at.
③adj./adv. + eno ugh to …
The boy is old eno ugh to go to school.
④too…to …
His eyesight is too poor to read such small letters.
(5) only to find , only to be told 出乎意料之外的结果
3. 原因不定式可以用于动词、形容词或-ed分词后表示原因。
He was too excited to get high marks.
八.同位语
Is this your purpose, to avoid being puni shed?
九.独立成分
To tell you the truth, I don ' t like you. They arrived here at 11:55 a.m., to be exact.
类似的有：to be fra nk 坦率地说，to hear him talk 听他说话的口气，to cut a long
story short 长话短说，等等。
C
不定式的各种结构
1 .宾格词+不定式
1 )普通结构此结构中的宾格词为名词或代词的宾格，宾格词是谓语动词的宾语，同时
又是不定式的逻辑主语，不定式和宾格词一起构成复合宾语。
I want Henry to come. She expects this to be true. I heard them sing yesterday.
2) “ there to be + 宾格词”结构
此结构的宾格词仍是不定式的逻辑主语，只是它位于不定式to be的后面。
I don ' t want there to be any misunderstanding.
3) 各种形式的不定式都可以用于此种结构中。
The judge wan ted the man to be puni shed.
He expected each of his stude nts to be worki ng hard for the coming exam.
2 .主格词+不定式
当上一种结构变为被动语态时，就出现了此种结构，此结构中，不定式都要带to 词是不定式的逻辑主语，不定式在句中作主语补足语。
They are allowed to go. J We allowed them to go.
He was see n to en ter the store. J I saw him en ter the store.
3 . for + 宾格词+不定式
此结构中，宾格词是不定式的逻辑主语，这种结构在句中可作：
1) 主语It is difficult for us to learn a second foreign Ianguage.
2 ) 宾语I con sider it n ecessary for her to lear n Fren ch.
3 ) 表语The best thing is for us to make our own decisi on.

Without anything to eat, he died of hun ger.
5 ?疑问词+不定式此结构相当于名词词组，在句中可作：
1) 主语When to visit that farm has not been decided yet.
2) 宾语We must know how to operate this mach ine.
3) 表语The problem now is how to collect eno ugh mon ey.
4) 同位语The problem what to do next is unknown.

按：本套资料省去了名词、代词、形容词等部分，保留了最最核心的句型和动词。希望能有所帮助。 第一章名词性从句 在句子中起名词作用的句子叫名词性从句。名词性从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。 一．主语从句 主语从句是在复合句中充当主语的从句，通常放在主句谓语动词之前或由形式主语it代替，而本身放在句子末尾。 1. It作形式主语和it引导强调句的比较 It作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分，都可用连词that。被强调部分指人时也可用who/whom。例如： a) It is a pity that you didn’t go to see the film. 你不去看那场电影真可惜。 - b) It doesn’t interest me whether you succeed or not.我对你成功与否不感兴趣。 c) It is in the morning that the murder took place.谋杀案是在早上发生的。（强调句型） d) It is John that broke the window.是John打碎的窗户。（强调句型） 2. 用it作形式主语的结构 (1) It is ＋名词＋从句 It is a fact that …; It is an honor that…; It is common knowledge that… (2) It is ＋形容词＋从句 It is natural that…It is strange that… . (3) It is ＋不及物动词＋从句 It seems that…It happened that…It appears that… (4) It ＋过去分词＋从句 It is reported that…It has been proved that…It is said that… 3. 主语从句不可位于句首的五种情况： （1）if引导的主语从句不可居于复合句句首。 （2）It is said /reported…结构中的主语从句不可提前。例如： 正确表达：It is said that President Jiang will visit our school next week. ( 错误表达：That President Jiang will visit our school next week is said. （3）It happens/occurs…结构中的主语从句不可提前。例如： 正确表达：It occurred to him that he failed in the examination. 错误表达：That he failed in the examination occurred to him. （4）It doesn’t matter how/whether …结构中的主语从句不可提前。例如： 正确表达：It doesn’t matter whether he is wrong or not. 错误表达：Whether he is wrong or not doesn’t matter. （5）含主语从句的复合句是疑问句时，主语从句不可提前。例如： ； 正确表达：Is it likely that it will rain in the evening 错误表达：Is that will rain in the evening likely 4. what 与that 在引导主语从句时的区别 what 引导主语从句时在句时在从句中充当句子成分，如主语．宾语．表语，而that 则不然。例如：
（1）表语从句 1．定义：用作表语的从句叫做表语从句。 2．构成：关联词+简单句 3．引导表语从句的关联词的种类： (1) 从属连词that。如： The trouble is that I have lost his address. 麻烦是我把他的地址丢了。 (2) 从属连词whether, as, as if。如： He looked just as he had looked ten years before. 他看起来还与十年前一样。 The question is whether they will be able to help us. 问题是他们是否能帮我们。 注：从属连词if一般不用来引导表语从句，但as if却可引导表语从句，如： All this was over twenty years ago, but it's as if it was only yesterday. gh能跟表语从句的谓语动词一般为系动词be, seem, look等。如： It looked as if it was going to rain. 看起来天要下雨了。 连接副词 where, when, how, why。 如：The problem is who we can get to replace her. 问题是我们能找到谁去替换她呢。 The question is how he did it. 问题是他是如何做此事的。 That was what she did this morning on reaching the attic. 那就是她今晨上了阁楼干的。 解释： 1．连词because可引导表语从句。如： I think it is because you are doing too much. 我想这是因为你做得太多。 2．在一些表示“建议、劝说、命令”的名词后面的表语从句中，谓语动词用虚拟语气。should+动词原形表示，should可省略。如： My suggestion is that we (should) start early tomorrow. 我的建议是我们明天一早就出发。（2）主语从句 1．定义：用作主语的从句叫做主语从句。 2．构成：关联词+简单句 3．引导主语从句的关联词有三类： (1) 从属连词that。如：That they were in truth sisters was clear from the facial resemblance between them. 很明显，她们确是亲姐妹，她们的脸型很相似。 (2) 从属连词whether。如： Whether he’ll come here isn’t clear. 他是否会来这里还不清楚。 (3) 连接代词who, whom, whose, what, which, whoever, whatever, whichever 连接副词 where, when, how, why。如： What she did is not yet known. 她干了什么尚不清楚。 How this happened is not clear to anyone. 这事怎样发生的，谁也不清楚。 Whoever comes is welcome. 不论谁来都欢迎。 Wherever you are is my home ---- my only home. 你所在的任何地方就是我的家----我唯一的家。 解释： 1．主语从句能用it作形式上的主语。常以it作形式主语的句型有： A. It+be+形容词(obvious, true, natural, surprising, good, wonderful, funny, possible, likely, certain, probable, etc.)+that从句。如： It is certain that she will do well in her exam. 毫无疑问她考试成绩会很好。 It is probable that he told her everything. 很可能他把一切都告诉她了。 B. It+be+名词词组(no wonder, an honour, a good thing, a pity, no surprise, etc.)+that

高中英语语法难点——并列句和主从复合句并列句基本概念： 并列复合句是由两个或两个以上并列而又独立的简单句构成。两个简单句常由并列连接词连在一起；但有时不用连接词,只在两个简单句之间用一逗号或分号。2、常见的并列句： (1) 用来连接两个并列概念的连接词有and , not only…but also…, neither…nor…等,and 所连接的前后分句往往表示先后关系、递进关系。前后分句的时态往往保持一致关系,若第一个分句是祈使句,那么第二个分句用将来时。(2) 表示在两者之间选择一个, 常用的连接词有or,otherwise,or else,either…or…等,前后分句的时态往往保持一致关系,若第一个分句是祈使句,那么第二个分句用将来时。(3) 表明两个概念彼此有矛盾、相反或者转折, 常用的连接词有but,yet,still ,however等,前后分句时态一致。(4) 说明原因, 用连接词for ,前后分句时态一致。(5) 表示结果,用连接词so, 前后分句时态一致。 主从复合句 1、概念： 主从复合句由一个主句和一个或一个以上的从句构成。主句为句子的主体,从句只用作句子的一个次要成分,不能独立成为一个句子。从句通常由关联词引导,并由关联词将从句和主句联系在一起。如：While the grandparents love the children, they are strict with them.(爷爷奶奶们很爱孩子,同时对他们也严格要求。) / It seemed as if the meeting would never end.(看起来会议没完没了。) / Hurry up, or (else) you’ll be late.(快点, 要不然就来不及了。) / However I cook eggs, the child still refuses to eat them.(不管我用什么方法煮鸡蛋,小孩还是不肯吃。) 2、分类： 从句按其在复合句中的作用,分为主语从句、表语从句、宾语从句、定语从句和状语从句等。(参见以下各条) 3、各从句在句子中的位置以及用法： (1) 表语从句：在句子中作连系动词的表语的从句,它位于主句中的系动词之后。例如：That is why he did not come to school yesterday. / It is because you are so clever. (2) 宾语从句：在句子中作及物动词或介词的宾语。①基本形式：(主句＋)连词+从句主语+从句谓语+... ②关于宾语从句连词的选择：若从句来源于一个陈述句,那么,连词用that,在口语中that可以省略; 若从句来源于一个一般疑问句,连词则用if 或whether; 若从句来源于一个特殊疑问句,则连词就是疑问词(如what,who,where,when等) 例如：They believe that the computer will finally take the place of human beings.(他们相信计算机终将代替人类。) (从句本来就是陈述句)/ I wonder whether I should say something for him to the headmaster. (我不知道是不是该为他在校长跟前说点什么。) (从句来源于一般问句Shall I say something for him to the headmaster?) / He asked me where he could get such medicine. (他问我在哪儿能搞到那样的药。) (从句来源于特殊问句Where can he get such medicine? ) ③宾语从句的时态问题：如果主句是现在时,从句则用现在某一时态,甚至可以用过去时；如主句是过去时,从句则相应地使用过去某一时态,遇到客观真理时仍然用现在时。如：I think I will do better in English this term. (我想本学期我的英语会学得好点。) / The teacher asked the boy if the earth is round. (老师问那个男孩地球是不是圆的。) ④下列结构后面的从句一般也作为宾语从句看待：be sorry / afraid / sure / glad +that从句,如：I’m sorry I’m late. (对不起,我迟到了。) / I’m afraid he isn’t in at the moment. (恐怕他此刻不在家。) (3) 状语从句：在复合句中作状语,其位置可以在主句前或主句后。状语从句可以分为时间、地点、原因、目的、结果、比较、让步、条件等几种。状语从句由从属连接词引导。时间状语从句通常由when ,as ,while, after, before, since, as soon as ,since, till (until), while, whenever 等
高中英语语法大全之形容词和副词 形容词及其用法 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）He is an ill man. （对）The man is ill. （错）She is an afraid girl. （对）The girl is afraid. 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： something nice 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：(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 The Times is a daily paper. The Times is published daily. 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 poor are losing hope. 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。 the British，the English，the French，the Chinese. The English have wonderful sense of humor. 多个形容词修饰名词的顺序 多个形容词修饰名词时，其顺序为： 限定词--数词--描绘词--(大小，长短，形状，新旧，颜色) --出处--材料性质，类别--名词 a small round table a tall gray building
巧记跟不定式和动名词做宾语的动词用法 语法体现语言的规律,学好英语离不开语法学习。其中，动词的用法是重点，也是难点。对于谓语动词和非谓语动词的用法，学生普遍感到困难。学生感到50多个动词，用法难以掌握，但调整了单词的排列顺序，根据汉意编写顺口溜会方便记忆： （一）跟不定时作宾语的动词有： 打算(intend)计划(plan)和期盼(expect/desire) 假装(pretend)喜欢(would like/love/prefer)表祝愿(wish) 决定(decide)同意(agree)来帮助(help) 设法(manage)说服(persuade)不拒绝(refuse) 好像(seem/appear)答应(promise)做努力(attempt) 选择(choose)询问(ask)多学习(learn) 告诉(tell)失败(fail)也付得起(afford) 不定式宾语要牢记！ （二）跟动名词作宾语的动词有： 考虑（consider）完成（finish）多练习（practise） 避免（avoid）冒险（risk）求建议（suggest/recoomend） 面对（face）喜欢（enjoy/appreciate）和介意(mind) 允许（allow）承认（admit/permit）或放弃(give up/abandon) 推迟（put off/delay/postphone）逃避（escape）不原谅（excuse/pardon）提及（mention）坚持(keep/insist on）要想象（imagine/fancy） 还有词组feel like 和can’t stand！ 瞧！，我们就这样快快乐乐地记住了吧！ （三）在动词remember, try, regret, forget, need/want/require， stop, mean等后跟动名词V-和不定式意义不同，巧记一句话（记住努力；后悔忘记；需要停止；很有意义），学习采用对比法： remember to do something记着去做某事（现在还没有做） remember doing something记着曾做过某事（以前做过某事） try to do something努力、尽力做某事 try doing something试着做某事（看能否达到预期的结果） stop to do something开始做某事（停下正在做的事，开始做另一事） stop doing something停止做某事（停止正在做的事） regret to do something对将来做的事感到遗憾、惋惜 regret doing something对已经做过的事感到后悔
