高中英语重点语法知识汇总(最新整理)

介词和介词短语

1、介词是一种用来表示词与词、词与句之间的关系的虚词，在句中不能单独作句子成分。介词后面一般有名词代词或相当于名词的其他词类，短语或从句作它的宾语。介词和它的宾语构成介词词组，在句中作状语，表语，补语或介词宾语。介词可以分为时间介词、地点介词、方式介词和其他介词。

1）时间介词：at, in, after, by, before, during, since, for, until, from 2）地点介词：in, at, on, over, under, below, near, behind, by

3）方式介词：with, by, like, in, without等

2、介词和其他代词或名词搭配形成介词短语。介词短语在句中可以作状语，定语，表语，补足语等。

1）作表语例如：It was in 2005 in Beijing.

2）作宾语补足语例如：He found his dog outside the station.

3）作后置定语例如：I even store them in boxes under my bed.

4）作状语例如：You are supposed to put your bread on your plate.

状语从句

1、地点状语从句地点状语从句通常由where, wherever 引导。

Where I live there are plenty of trees.

我住的地方树很多。

Wherever I am I will be thinking of you.

不管我在哪里我都会想到你。

2、方式状语从句方式状语从句通常由as, (just) as…so…, as if, as though引导。

1）as, (just) as…so…引导的方式状语从句通常位于主句后，但在(just) as…so…结构中位于句首，这时as从句带有比喻的含义，意思是“正如…”，“就像”，多用于正式文体，例如：

Always do to the others as you would be done by.

你希望人家怎样待你，你就要怎样待人。

As water is to fish, so air is to man.

我们离不开空气，犹如鱼儿离不开水。

Just as we sweep our rooms, so we should sweep backward ideas from our minds.正如打扫房屋一样，我们也要扫除我们头脑中落后的东西。

2）as if, as though

两者的意义和用法相同，引出的状语从句谓语多用虚拟语气，表示与事实相反，有时也用陈述语气，

表示所说情况是事实或实现的可能性较大。汉译常作“仿佛……似的”，“好像……似的”，例如：

They completely ignore these facts as if (as though) they never existed. 他们完全忽略了这些事实，就仿佛它不存在似的.（与事实相反谓语用虚拟语气）

He looks as if (as though) he had been hit by lighting.

　他那样子就像被雷击了似的。（与事实相反，谓语用虚拟语气。）

It looks as if the weather may pick up very soon.

看来天气很快就会好起来。（实现的可能性较大，谓语用陈述语气。）

说明：as if / as though也可以引导一个分词短语、不定式短语或无动词短语，例如：

He stared at me as if seeing me for first time.

他目不转睛地看着我，就像第一次看见我似的。

He cleared his throat as if to say something.

他清了清嗓子，像要说什么似的。

The waves dashed on the rocks as if in anger.

波涛冲击着岩石，好像很愤怒。

3、原因状语从句

比较：because, since, as和for

1）because语势最强，用来说明人所不知的原因，回答why提出的问题。当原因是显而易见的或已

为人们所知，就用as或 since。

I didn't go, because I was afraid.

Since /As the weather is so bad, we have to delay our journey.

2）由because引导的从句如果放在句末，且前面有逗号，则可以用for来代替。但如果不是说明直

接原因，而是多种情况加以推断，就只能用for。

He is absent today, because / for he is ill.

He must be ill, for he is absent today.

4、目的状语从句

表示目的状语的从句可以由that, so that, in order that, lest, for fear that, in case

等词引导，例如：

You must speak louder so that /in order that you can be heard by all. He wrote the name down for fear that(lest) he should forget it.

Better take more clothes in case the weather is cold.

5、结果状语从句

结果状语从句常由so… that 或such…that引导，掌握这两个句型，首先要了解so 和 such

与其后的词的搭配规律。

比较：so和 such

其规律由so与such的不同词性决定。such 是形容词，修饰名词或名词词组，so 是副词，只能修饰

形容词或副词。so 还可与表示数量的形容词many, few, much, little连用，形成固定搭配。

so foolish such a fool

so nice a flower such a nice flower

so many / few flowers such nice flowers

so much / little money. such rapid progress

so many people such a lot of people

（so many 已成固定搭配，a lot of 虽相当于many，但a lot of 为名词性的，只能用such搭配。）

so…that与such…that之间的转换即为 so与such之间的转换。

The boy is so young that he can't go to school.

He is such a young boy that he can't go to school

6、条件状语从句

连接词主要有 if, unless, as/so long as, on condition that 等。.

if 引导的条件句有真实条件句和非真实条件句两种。非真实条件句已在虚拟语气中阐述。

unless = if not.　

Let's go out for a walk unless you are too tired.

If you are not too tied, let's go out for a walk.

典型例题

You will be late ___ you leave immediately.　

A. unless

B. until

C. if

D. or

答案：A。句意：除非你立即走，否则你就回迟到的。可转化为If you dong leave immediately,

you will be late.　B、D句意不对，or表转折，句子如为 You leave immediately or

you will be late.

7、让步状语从句

though, although

　注意：当有though, although时，后面的从句不能有but，但是though 和yet 可连用

Although it's raining, they are still working in the field.　

　虽然在下雨，但他们仍在地里干活。

He is very old, but he still works very hard.　

　虽然他很老，但仍然努力地工作。

Though the sore be healed, yet a scar may remain.

　伤口虽愈合，但伤疤留下了。（谚语）

典型例题

1）___ she is young, she knows quite a lot.　

A. When

B. However

C. Although

D. Unless

答案：C。意为虽然她很年轻，却知道许多。

2）as, though 引导的倒装句

　as / though引导的让步从句必须表语或状语提前（形容词、副词、分词、实义动词提前）。

Child as /though he was, he knew what was the right thing to do. = Though he was a small child, he knew what was the right thing to do.

注意：a. 句首名词不能带任何冠词。

b. 句首是实义动词，其他助动词放在主语后。如果实义动词有宾语和状语，随实义动词

一起放在主语之前。

Try hard as he will, he never seems able to do the work satisfactorily. = Though he tries hard, he never seems…

虽然他尽了努力，但他的工作总做的不尽人意。

3）ever if, even though.　即使

We'll make a trip even though the weather is bad.

4）whether…or　不管……都

Whether you believe it or not

5）"no matter +疑问词" 或"疑问词+后缀ever"

No matter what happened, he would not mind.

Whatever happened, he would not mind.

　替换：no matter what = whatever

no matter who = whoever

no matter when = whenever

no matter where = wherever

no matter which = whichever

no matter how = however

　注意：no matter 不能引导主语从句和宾语从句。

　（错）No matter what you say is of no use now.

　（对）Whatever you say is of no use now.

你现在说什么也没用了。(Whatever you say是主语从句)

　（错）Prisoners have to eat no matter what they're given,

　（对）Prisoners have to eat whatever they're given.　囚犯们只能给什么吃什么。

8、比较while, when, as

1）as, when 引导短暂性动作的动词。

Just as / Just when / When I stopped my car, a man came up to me.

2）当从句的动作发生于主句动作之前，只能用when 引导这个从句，不可用as 或 while。

When you have finished your work, you may have a rest.

3）从句表示"随时间推移"连词能用as，不用when 或while。

As the day went on, the weather got worse.　

　日子一天天过去，天气越变越坏。

9、比较until和till

此两个连词意义相同。肯定形式表示的意思是"做某事直至某时"，动词必须是延续性的。否定

形式表达的意思是"直至某时才做某事"。动词为延续性或非延续性都可　以。正确使用这两

个连词的关键之一就在于判断句中的动词该用肯定式还是否定式。

肯定句：

I slept until midnight. 我一直睡到半夜时醒了。

Wait till I call you.　等着我叫你。

（在肯定句中可用before代替Let's get in the wheat before the sun sets.）否定句：

She didn't arrive until 6 o'clock.

她直到6点才到。

Don't get off the bus until it has stopped.

公共汽车停稳后再下车。

I didn't manage to do it until you had explained how.　直到你教我后，我才会做。

10、表示"一…就…"的结构

hardly/scarcely…when/before, no sooner…than　和as soon as都可以表示"一…就…"的意思，例：

I had hardly / scarcely got home when it began to rain.

I had no sooner got home than it began to rain.

As soon as I got home, it began to rain.

注意：如果hardly, scarcely 或no sooner置于句首，句子必须用倒装结构： Hardly / Scarcely had I got home when it began to rain.

No sooner had I got home than it began to rain

过去分词

1、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。

2、过去分词的否定式

过去分词前加not构成否定式。如：

He escaped, not seen by anyone. 他逃走了，没有人看见。

3、过去分词基本用法

1）作定语

过去分词用作定语，如果是单个词，常置于其所修饰的名词之前；过去分词短语用作定语时，一般

置于其所修饰的名词之后，其意义相当于一个定语从句，但较从句简洁，多用于书面语中。如：

We must adapt our thinking to the changed conditions.

我们必须使我们的思想适应改变了的情况。

The concert given by their friends was a success.

他们朋友举行的音乐会大为成功。

The meeting, attended by over five thousand people, welcomed the great hero.

他们举行了欢迎英雄的大会，到会的有五千多人。

2）作表语

过去分词作表语，主要是表示主语的状态，被动语态则表示动作。如：

The cup was broken by my little sister yesterday. 茶杯是昨天我小妹打碎的。(是被动语态，

表示动作)

The library is now closed. 图书馆关门了。(过去分词作表语)

3）作补语

补语说明宾语或主语所处的状态。如：

I was glad to see the child well taken care of.

我很高兴看到孩子受到了很好的照料。

The old man had his wallet stolen.

注意：如have这样的使役动词后，也可用不带to的不定式（动词原形）或现在分词作宾补。如：

They had me repeat the massage.

He had them working for him day and night.

4）作状语

过去分词作状语，修饰谓语，大多说明动作发生的背景过情况，表示时间、条件、

原

因、伴随情况

等。

一般说来，这一结构的逻辑主语是主句的主语。

Asked why he was late, he went red. （时间状语）

问他为什么迟到了，他涨红了脸。

Given more time, we could have done it better. （条件状语）如果给我们的时间多一些，我们会做得更好。

Inspired by what he said we are determined to study harder.（原因状语）

在他的话的鼓舞下，我们决心更加努力学习。

5）过去分词短语作独立成分

有些过去分词短语如：compared with（to），given（that）是固定的用法，

在句子中作状语。如：

Compared with her mother, she is tall.

与它妈妈相比，她算很高了。

Given his support, I think we’ll win the election.

如果获得他的支持，我想我们会赢得这次选举。

副词

1、副词及其基本用法副词主要用来修饰动词，形容词，副词或其他结构。

1）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。

We could see very clearly as trange light ahead of us.

b.方式副词well，badly糟、坏，hard等只放在句尾。

HespeaksEnglishwell.

2、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。　

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)IverylikeEnglish. (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。

I don't know him well enough.

The reise nough food fore very one to eat. Thereisfoodenoughforeveryonetoeat.

3、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”　

He is sitting close to me. Watch him closely.

2）late与lately late意思是“晚”；lately意思是“最近”　

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” He pushed the stickdeepinto 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

The plane was flying high. It hink 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” 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” You can eat free in my restaurant whenever you like. You may speak freely; say what you like.

现在分词

1、现在分词的两个基本特点

1）在时间上表示动作正在进行。例如：a developing country.一个发展中的国家，boiling water沸水， rising sun冉冉升起的太阳。（试比较：a developed country一个发达国家，boiled water沸水，risen sun 升起的太阳）

2）在语态上表示主动。例如：the ruling class统治阶级，the exploiting class剥削阶级。（试比较:the ruled class被统治阶级，the exploited class被剥削阶级）

2、现在分词的基本功能

1）现在分词作定语，表示正在进行的或主动的动作。也可以说明被修饰词的性质和特征，此时可换成相应的定语从句。

①There was a terrible noisefollowing the sudden burst of light.

②Hesaw a flying bird and raised his bow.

③I was satisfied with the exciting speech.

2）现在分词作状语时，可作时间、条件、结果、原因和伴随状语，表示正在进行的或主动的动作。

此时分词的逻辑主语就是主句的主语，因此要注意人称、时态和语态的一致性。　

①The visiting minister expressed his satisfaction with the talks, adding

that he had enjoyed his stay here.

②European foot ball is played inmore than 80countries, making it the most popular sport in the world.

③Seeing from the top of the hill,we can find that the city looks more beautiful.

3）现在分词作补足语，表示正在进行的或主动的动作。

①Soon they could see the steam rising from the wet clothes.

②The missing boys were last seen playing near the river.

4）现在分词的独立主格结构作状语。　

①Withhislipsstilltrembling,hecouldn'tsayaword.

②“Mama!”hecriedsuddenly,tearsrollingdownhischeeks.

“妈妈！”他突然哭着喊，泪水从他的脸上流下来。

（这里需要用现在分词的独立主格结构tearsrollingdownhischeeks作状语。） ③Weather permitting,we'llgo to the Great wall.如果天气允许的话，我们就去

长城。

（这里需要用现在分词的独立主格结构Weatherpermitting作状语。）

3、现在分词的否定结构　现在分词的否定式由“not+现在分词”构成。

Not knowing where togo, she went to the police for help.

她不知道该往哪儿走，就去请警察帮助。(现在分词一般式的否定结构)

Nots eeing John, I asked where he was.

我看不见约翰，于是问他在何处。（现在分词一般式的否定结构）

Not being seen by any one, the thiefe scaped.

那个贼趁无人看见时逃跑了。（现在分词被动式的否定结构）

Not having done it right, I tried again.

我由于没有做对，所以又试了试。（现在分词完成式的否定结构）

不定冠词

1、不定冠词a (an)与数词one 同源，是"一个"的意思。a用于辅音音素前，一般

读作[e]，而an则用于元音音素前，一般读做[en]。

1）表示“一个”，意为one；指某人或某物，意为a certain。

A Mr. Ling is waiting for you.

2）代表一类人或物。

A knife is a tool for cutting with.

Mr. Smith is an engineer.

3）词组或成语。

/ in a hurry / in a minute / in a word

/ in a short while / after a while / have a cold / have a try / keep an eye on /

2、不定冠词的位置

不定冠词常位于名词或名词修饰语前。注意：　

a. 位于下列形容词之后： such，what，many，half，

I have never seen such an animal.

Many a man is fit for the job.

　b. 当名词前的形容词被副词as, so, too, how, however, enough修饰时，不定冠词应放

在形容词之后：

It is as pleasant a day as I have ever spent.

So short a time.

Too long a distance.

c. quite，rather与单数名词连用，冠词放在其后。

但当rather，quite 前仍有形容词，不定冠词放其前后均可。如：quite a lotd.

d. 在as，though 引导的让步状语从句中，当标语为形词修饰的名词时不定冠词放形容词后：

Brave a man though he is，he trembles at the sight of snakes.

他尽管勇敢，可见到蛇还是发抖。

　当名词被比较级形容词修饰时，不定冠词通常置于比较级形容词之后。

一般现在时

一般现在时。表示通常性、规律性、习惯性的状态或者动作（有时间规律发生的事件）的一种时间状态。

1、表示经常的或习惯性的动作，常与表示频率的时间状语连用。

e.g. If you come, we will wait for you.

7、表示格言或警句中。　

e.g. Pride goes before a fall.　骄者必败。　

　情态动词

1、情态动词的语法特征

1）情态动词不能表示正在发生或已经发生的事情，只表示期待或估计某事的发生。2）情态动词除ought 和have 外，后面只能接不带to 的不定式。

3）情态动词没有人称，数的变化，即情态动词第三人称单数不加-s。

4）情态动词没有非谓语形式，即没有不定式，分词，等形式

2、比较can 和be able to

1）can could 表示能力；可能 (过去时用could),

只用于现在式和过去式(could)。be able to可以用于各种时态。

3、比较may和might

1）表示允许或请求；表示没有把握的推测；may 放在句首，表示祝愿。

May God bless you!

He might be at home.

注意：might 表示推测时，不表示时态。只是可能性比may 小。

2）成语：may/might as well，后面接不带to 的不定式，意为"不妨"。

注意：could, might表示推测时不表示时态，其推测的程度不如can, may。7、情态动词+ have +过去分词

1）may(might) have + done sth, can (could) have + done sth表示过去，推测过去时间里可能发生的事情。

Philip may (might) have been hurt seriously in the car accident.

Philip can (could) have been hurt seriously in the car accident.

2）must have +done sth，对过去时间里可能发生的事情的推测，语气较强，具有“肯定”，“谅必”的意思。

---Linda has gone to work, but her bicycle is still here.

---She must have gone by bus.

3）ought to have done sth, should have done sth

　本应该做某事，而事实上并没有做。否定句表示“不该做某事而做了”。

You ought to (should) have been more careful in this experiment.

He ought not to have thrown the old clothes away.（事实上已扔了。）

ought to 在语气上比should 要强。

4）needn't have done sth　本没必要做某事

8、should 和ought to

should 和ought to 都为"应该"的意思，可用于各种人称。

---Ought he to go?

---Yes. I think he ought to.

表示要求，命令时，语气由should（应该）、had better最好）、must （必须）渐强。

9、had better表示"最好"

had better 相当于一个助动词，它只有一种形式，它后面要跟动词原形。

had better do sth

had better not do sth

It is pretty cold. You'd better put on my coat.

She'd better not play with the dog.

had better have done sth表示与事实相反的结果，意为"本来最好"。

You had better have come earlier

10、would rather表示“宁愿”

would rather do

would rather not do

would rather… than…　宁愿……而不愿。

还有would sooner, had rather, had sooner都表示"宁愿"、"宁可"的意思。

If I have a choice, I had sooner not continue my studies at this school.

I would rather stay here than go home. = I would stay here rather than go home.

典型例题

----Shall we go skating or stay at home?

----Which ___ do?

A. do you rather

B. would you rather

C. will you rather

D. should you rather

答案B。本题考查情态动词rather的用法，would rather +do sth 意为"宁愿"，本题为疑问句，would 提前，所以选B

11、will和would 注意：

1）would like； Would like to do = want to 想要，为固定搭配。

Would you like to go with me?

2）Will you…?　Would you like…? 表示肯定含义的请求劝说时，疑问句中一般用some, 而不是any。 Would you like some cake?

3）否定结构中用will，一般不用would, won't you是一种委婉语气。

Won't you sit down?

12、情态动词的回答方式

问句肯定回答否定回答

Need you…?　Yes, I must.　No, I needn't/don't have to.

Must you…?Yes, I must.　No, I needn't/don't have to.

典型例题

1）---Could I borrow your dictionary?

---Yes, of course, you____.　

A. might

B. will

C. can

D. should

　答案C. could表示委婉的语气，并不为时态。答语中of course，表示肯定的语气，允许某人做

某事时，用can和may来表达，不能用could或might。复习：will 与you连用，用来提出要求

或下命令。should与you 连用，用来提出劝告。

2）---Shall I tell John about it?

---No, you ___. I've told him already.

A. needn't

B. wouldn't

C. mustn't

D. shouldn't

答案A。needn't 不必，不用。wouldn't 将不, 不会的。mustn't 禁止、不能。shouldn't

不应该。本题为不需要，不必的意思，应用needn't。

3）---Don't forget to come to my birthday party tomorrow.

---______.

A. I don't

B.　I won't

C. I can't

D. I haven't

　答案B.　will既可当作情态动词，表请求、建议、也可作为实义动词表“意愿、意志、决心”，本题表示决心，选B。

13、带to 的情态动词带to 的情态动词有四个：ought to, have to, used to, be to, 如加上have got to ,(=must),

be able to，为六个。它们的疑问，否定形式应予以注意：

Do they have to pay their bill before the end of the month?

She didn't use to play tennis before she was fourteen.

You ought not to have told her all about it.

Ought he to see a heart specialist at once.?

ought to 本身作为情态动词使用。其他的词作为实义动词使用，变疑问，否定

时，须有do 等助动词协助。

Tom ought not to ___ me your secret, but he meant no harm.　

A. have told

B. tell

C. be telling

D. having told

答案A。由于后句为过去时，告诉秘密的动作又发生在其前因，此地应用过去完成时，但它在情态动词 ought to 后，所以用have。

14、比较need和dare

这两词既可做实义动词用，又可做情态动词用。作为情态动词，两者都只能用于疑问句，否定句和条件句。 need 作实义动词时后面的不定式必须带to，而dare作实义动词用时, 后面的to 时常可以被省略。

1）实义动词： need　（需要, 要求） need + n. / to do sth

2）情态动词： need，只用原形need后加do，否定形式为need not。

Need you go yet? Yes, I must. / No, I needn't.

3）need 的被动含义：need, want, require, worth（形容词）后面接doing也可以表示被动： need doing = need to be done

动词短语

由动词和动短语成,或以动词为中心,功能同动词的短语叫动词短语,动词短语是动词的一种固定搭配形式，动词短语的搭配可分为下列四种基本类型。

1、动词+副词

1）作及物动词，例： He brought up his children strictly.

从以上的例句中可以看出，在“动词+副词”的词组中宾语位置有两种情况：宾语如是名词，可置副词后面，亦可置于动词和副词之间。而如果宾语是代词，只能置于动词后面，即动词和词之间。

2）作不及物动词，例： Something unexpected has turned up． 出现了令人意外的情况。（turn up=appear）

3）既可作及物动词又可作不及物动词，例：

The barrel of gunpowder blew up．（不及物）火药桶爆炸了。

The soldiers blew up the bridge．（及物）士兵们把桥炸毁了。

2、动词+介词

　动词与介词构成的词组在词义上相当于一个及物动词，宾语总是在介词后面，例： I don’t much care for television．我不很喜欢电视。（care for=like）3、动词+副词+介词

　在这类动词短语中，动词、副词、介词紧密结合，是动副词组和动介词组的合成体，词义上相当一个及物动词。它兼有以上两类短语动词的特点，但宾语总是位于介词之后，例：

We must work hard to make up for lost time．

我们必须努力工作来弥补失去的时间。（make up for＝compensate）

4、动词+名词

　这类动词短语中的常见动词是have，take，give，make等，后面的名词通常是从动词转化而来的作名词，并表达了短语动词的真正意义，例：

Let’s have another try. 让我们再试一下。（have a try=v. try）　

5、动词+名词+介词

这类动词短语只用作及物动词。名词前可加形容词说明程度，宾语总是位于介词之后, 例：Keep an eye on the baby while I am out．我不在家时请照看一下小孩子。

6、be+形容词（包括过去分词作形容词）+介词

这类动词短语也相当于及物动词，宾语位于介词后面，形容词是短语动词的真正词义，例：I know he is slow at understanding，but you have to be patient with him．我知道他理解力差，但你得对他耐心些。
