英语语法中的重点难点

英语语法中的重点难点

士兵们把这个美国人送到李将军那里。

导语:英语的语法很复杂,有很多知识点是很难掌握的,下面是我收集整理的英语语法中的重点难点,欢迎参考!

主谓一致常考难题:

1. Five minutes is enough to do this exercise.

Each boy and each girl wants to serve the people in future.

More than one student has seen the film.

Many a ship has been damaged in the storm.

More members than one are against your plan.

一些有两个部分构成的名词表示衣物或工具作主语时, 谓语通常用复数形式:glasses, clothes, trousers, shoes, compasses, chopsticks, scissors等。

但如果主语用a kind of , a pair of , a series of等加名词构成时, 谓语动词一般用单数形式。A pair of shoes was on the desk.

并列主语如果指的是同一个人、同一事物或同一概念时, 谓语动词用单数形式, 这时and后面的名词没有冠词。例如:

Truth and honesty is the best policy.

The girl's teacher and friend is a young doctor.

To love and to be loved is the great happiness.

Going to bed early and getting up early is a good habit.

A knife and fork is on the table.

当主语后面跟有as well as, as much as , no less than, along with, with, like, rather than, toger with, but, except, besides, including, in addition to等的词组时, 其谓语动词的单、复数按主语的单、复数而定。例如:

The teacher as well as the students was excited.

The room with its furniture was rented.

2. A (great) number of修饰可数复数名词, 谓语动词用复数; a great deal of,a large amount of 修饰不可数名词, 其短语作主语时, 谓语动词用单数。

3. 关系代词who, that, which等在定语从句中作主语时, 其谓语动词的数应与句中先行词的数一致。例如:

Those who want to go please sign your names here.

Some of the energy that is used by man comes from the sun.

1/2 one(a) half 1/4 one(a) quarter

5. 形容词的顺序:

系动词be,grow,get,become,feel,appear,prove,seem,look,keep,ell,taste,sound,turn,remain限定词+数量形容词(序数词在前,基数词在后)+性状形容词+大小、长短、高低等形体+新旧+颜色+国藉+材料

Those three beautiful large square old brown wood table

6. 某些以a-开首的形容词例如:afraid,alike,alone,asleep,awake, alive 等只能作表语,不能作定语。

某些以-ly结尾的词是形容词而不是副词:friendly,lively, lovely,lonely,likely,deadly,silly,orderly, timely等。

worse worst little less least表示一方不及另一方时,用“less+原级+than”的结构表示:This room is less beautiful than that one.

表示一方超过另一方的程度或数量时,可在比较级前加表示程度的状语,如:n,a lot,a bit,a little,still,much,far, yet, by far等修饰:He works n harder than before.

注意:by far 通常用于强调。用于比较级时,一般放在比较级的后面, 如放在前面,应在二者中间加“the”。He is taller by far than his brother.

He is by far the taller of the two brothers.

某些以-or结尾的形容词进行比较时,用to代替than。superior,junior,senior等。He is superior to Mr Wang in mathematics.

在比较从句中为了避免重复通常用that(those),one(ones)代替前面出现的名词。that指物,one既可指人,也可指物。that可代替可数名词单数和不可数名词,而one只能代替可数名词。例如:

The book on the table is more interesting than that on the desk.

A box made of iron is stronger than one made of wood.

8. 表示倍数的比较级有如下几种句型:

A is three (four,etc.) times the size (height, length, width,etc) of B.

The new building is four times the size (the height) of the old one.

这座新楼是那座旧楼的四倍大(四倍高)。[高三倍]

A is three (four, etc.) times as big (high, long, wide, etc.) as B.

Asia is four times as large as Europe.是欧洲的四倍大。

A is three (four,etc.) times bigger (higher, longer, wider) than B.

例如:Your school is three times bigger than ours.

你们的学校比我们的学校大三倍。表示两倍可以用 tw 或 double。

9. 表示“程度”的形容词,如excellent,extreme,perfect等,没有,也不能用比较级。

如果复数名词前有many、few,不可数名词前有much、little等表示量的形容词时,该用so而不用such。如:

I've had so many falls that I'm black and blue all over.

Mr White got so little money a month that he could hardly keep body andsoul toger.

但little不表示数量而表示“小”的意思时,仍用such。如:

They are such little children that the they cannot clean the house by themselves.

10. almost与nearly

在very, pretty, not后用nearly, 不用almost。例如:I'm not nearly ready.

在any, no, none, nr前用almost, 不用nearly。例如:I almost nr see her.

11. need 表示“需要”或“必须”,作情态动词时,仅用于否定句或疑问句中。在肯定句中一般用must, he to, ought to或should 代替。例如:

You needn't come so early.

Need I finish the work today? --Yes, you must.

注意:needn't he done“表示本来不必做某事而实际上做了某事”。例如:You needn't he waited for me.

“should he done”表示应该做到而实际上没有做到。

You should he started earlier.

“ought to he done”表示过去应做某事而实际未做。

You ought to he ed him (but you didn't)

书报的标题,等情节介绍常用一般现在时。

表示感觉,愿望和状态的某些动词如he, be, hear, see, like等词一般不用进行时。

有些动词形式上是主动结构,但表示被动的意思。常见的有可和 well, easily 等副词连用的不及物动词sell,wash,write,read,clean,cook等。例如:

The cloth washes well.这布很经洗。

The new product sells well.这新产品很畅销。

The pen writes well.这支笔很好写。

在动词 arrange,command, demand, desire,insist, order,proe, request, require, suggest等后面的宾语从句中用“(should)+ 动词原形”(虚拟语气)例如:

We suggested that we (should) he a meeting.

The doctor ordered that she (should) stay in bed for a few days.

He demanded that we (should) start right away.

作a,idea,order,demand,plan,proal,suggestion,request等名词的表语从句和同位语从句,其谓语动词要用虚拟语气的结构“(should)+动词原形”。例如:We all agreed to his suggestion that we(should) go to Beijing for sightseeing.

My idea is that we (should) do exercises first.

在feel, hear, not, observe, see, watch, he, let, make等词后的补足语中,不定式不带to。但是这些句子如果变成被动结构时,就必须带to。例如:I often hear him sing the song.

He is often heard to sing the song.

注意:不定式动词在介词but, except, besides后面时,如果这些介词之前有行

为动词do的各种形式,那么,这些介词后的`不定式不带to,否则要带to.如:

She could do nothing but cry.

What do you like to do besides swim?

I he no cho but to go.

作定语的不定式如果是不及物动词,或者不定式所修饰的名词或代词是不定式动作的地点、工具等,不定式后面须有相应的介词。例如:He is looking for a room to live in. There is nothing to worry about.

Please give me a knife to cut with.

There / It is no use/ good/ not any use/ good/ useless doing sth.

动词后可以用动名词作宾语,但不能用不定式:

admit,appreciate, oid, consider, delay, enjoy, escape, excuse, feel like, finish, forgive, give up, imagine, include, keep, mention,mind,miss,practise, put off, resist, risk, suggest, can't , can't stand(无法忍受)等。

I tried doing it again.(我试着又干了一次。)]

mean to do 有意... mean doing意味着...

I mean to come early today.(我打算今天早些来。)

Missing the train means waiting for another hour.

(误了这趟火车意味着再等一个小时。)

allow, aise, forbid, permit

We don't allow oking here. We don't allow students to oke.

动词need,require,want作“需要”解,其后跟动词作它的宾语时,若表示的含义是被动的,必须用动名词,或不定式的被动式。例如:

The window needs(requires, wants)cleaning(to be cleaned).

在短语devote to, look forward to, pay attention to, stick to, be used to, object to,thank you for, excuse me for 等后的动词也必须用动名词形式:I look forward to hearing from you soon.

Badly polluted, the water cannot be drunk.(原因)

Being written in haste, the comition is full of mistakes.

(原因,强调写的过程,故应用现在分词一般被动式)

Hing been deserted by his guide, he couldn't find his way through the jungle.(为了强调已完成的动作)

这里 asked 可能意味着 hing been asked, 也可能意味着when/since I was asked, 但用了 hing been asked 就不会有歧义。

下面句中过去分词表示的时间与谓语动词所表示的时间相同,所以不能代之以强调先于谓语动词的现在分词完成被动式。例如:

Covered with confusion, I left the room.我很窘地离开了房间。

United, we stand; divided, we fall. 团结则存,分裂则亡。

He used to live in London, use(d)n't he /didn't he?

There used to be a cinema here before the war, use(d)n't there /didn't there?

Such things ought not to be allowed, ought they?

He ought to be punished, oughtn't he?

但在正式文体中,用ought we not形式。例如:

We ought to go, ought we not?或We ought to go ,should we not?

含有情态动词must的句子表示推则,作“想必”解时,疑问部分不可用mustn't。若前句强调对现在情况的推测,疑问部分用aren't(isn't)十主语,例如:You must be tired,aren't you?若陈述部分的must表示“有必要”时,附加疑问句部分则用needn't。例如:You must go home right now, needn't you?

当mustn't 表示禁止时,附加疑问部分一般用must。如:

You mustn't walk on grass, must you?

前句谓语动词是must he+过去分词时,若前句强调对过去情况的推测(一般有过去时间状语),疑问部分的谓语动词用didn't+主语;若前句强调动作的完成,疑问部分的谓语动词用hen't(hasn't)+主语, 例如:

He must he met her yesterday, didn't he?

You must he seen the film, hen't you?

陈述句谓语部分出现否定词缀时(前缀或后缀),疑问部分仍用否定结构。例如:He is unfit for his off, isn't he?

如果陈述部分包含有no, nr, hardly, seldom, few, little,nowhere, nothing等否定或半否定词时,疑问部分用肯定形式。例如:He is hardly 14 years old,is he?

如果陈述部分的主语为ryone,someone,no one等不定代词,其疑问部分的主语可用he,也可用they。

Everyone knows his job, doesn't he?

Everyone knows their job,don't they?

No one was hurt,were they?

I'm late, aren't I?

One can't be too careful,can one(you)?

He a cup of tea, will you?

Let's go there,shall we? Let us go there,will you?

同位语从句跟在名词后面,进一步说明该名词的具体内容。同位语从句的名词主要有fact, news, promise, idea, truth等。连接词用that (不用which)及连接副词how, when, where, why等。例如:

His delay is due to the fact that the car went wrong halfway.

The news that our team has won the match is true.

She asked the reason why there was a delay.

关联词只能用wher不能用if表示“是否”的情况如下:

A)在表语从句和同位语从句中。例如:

The question is wher the film is worth seeing.

The news wher our team has won the match is unknown.

B)在主语从句中,只有用it作形式主语时,wher和if都能主语从句,否则,也只能用wher。例如:

Wher we shall attend the meeting hasn't been decided yet.

It hasn't been decided wher(if)we shall attend the meeting.

C)在介词之后。(介词往往可以省略)例如:

D)后面直接跟动词不定式时。

He doesn't know wher to stay or not.

E)后面紧接or not 时。

We didn't know wher or not she was ready.

F)让步状语从句,只能用wher。

Wher you like it or not, you must do it well.

G)用if会引起歧义时。例如:Please let me know if you like it.

该句有两个意思:“请告诉我你是否喜欢”。

或“如果你喜欢,请告诉我。”用了wher就可以避免。

在下面几种情况下必须用“that”定语从句:

1)先行词是不定代词:all,few,little, much,soming,nothing,anything等。All that we he to do is to practise ry day.

2)先行词被序数词或形容词所修饰。

The first lesson that I learned will nr be forgotten.

3)先行词被all,any,ry, each, few,little,no,some, 等修饰。

I he read all the book (that) you ge me.

4)先行词被 the only, the very, the same, the last 修饰时。

He is the only person that I want to talk to.

5)先行词既有人又有物时。They talked of things and persons that they remembered in the school.

先行词是表示地点时,要根据从句的谓语动词是及物的还是不及物的。如果是及物的就用that(which),否则用where。

This is the house where he lived last year.

This is the house that (which) he visited last year.

用no sooner…than和hardly…when的从句表示“刚……就……”。主句中的动词一般用过去完成时,从句用过去时;而且主句一般倒装,把助动词had提到前面。例如:Hardly had I entered the room when I heard a loud noise.

代词作主语时,主谓语序不变。Here it is. Here he comes.

当句首状语为表示地点的介词词组时也常常引起全部倒装。

From the valley came a frightening sound.

表语置于句首时,倒装结构为“表语+连系动词+主语”。

Present at the meeting were Professor White,Professor Smith and many other guests.

Gone are the days when they could do what they liked to the Chinese people.

Among the goods are Christmas trees, flowers, candles and toys.

He has been to Beijing. So he I.

Li Wei can't answer the question. Neither can I.

部分倒装

用于省略if的虚拟条件状语从句。Had yoeviewed your lessons,you might he passed the examination.

3.用于“形容词(或名词、动词)+as(though)的让步状语从句中。例如:Pretty as she is ,she is not clr. Try as he would, he might fail again.

如果从句的表语是名词,其名词前不加任何冠词。

Child as he was, he had to make a living.

用于no sooner…than…,hardly…when和not until的句型中。Not until the teacher came did he finish his homework.

用于nr,hardly,seldom,scarcely, barely, little,often,at no time,not only,not once等词开头的句子。

Nr shall I do this again. Little did he know who the woman was.

6.用于以only开头的句子(only修饰副词,介词短语或状语从句时)。

Only in this way can you English.

Only when he told me did I realize what trouble he was in.

如果only后面的词组不是状语,则不用倒装。

Only Wang Ling knows this.

;

英语分数类主谓一致

10) 用在姓氏的复数名词之前,表示一家人:

two thirds是2/3的意思,句话中,crop作物,第二句话friend朋友,一般来讲这个句子应该是把作物当成是不可数来看待,朋友当成可数看待,才符合不可数用has,可数复数用he了,

但是crop用了复数,crops也是可数名词,其实这个是说话方式的问题,比如我们人说普通话也不会完完全全遵循语法,不遵循语法的句子可能外国人也觉得理解不了

所以不用过分纠结,在考试阶段,按照语法来做就可以,平时的一般考试或是习题可能不会那么严谨,正规考试不会出现那么模棱两可的题

90% / two third of the peoplIt all depends (on) wher they will support us.e in China 这里面应该就是分数或百分数加名词作主语了吧。希望能帮到你~

[编辑本段]动词语态

一、主动语态:

主语是谓语动作的使动方。也就是说谓语的动作源自主语,而施加于宾语。相反,被动语态中,主语是谓语动作的受动方,如果有宾语的,宾语往往是谓语动作的使动方。

在语法机构上,主动语态和被动语态的区别主要在于,主动语态直接使用动词原形作为谓语,然后再在该动词原形的基础上施加时态和其他语法;而被动语态则使用系词+动词的过去分词作为谓语,各种时态和其他语法也施加在系词上。

二、被动语态:

英语中的被动语态使用得比汉语要多,要普遍,许多课本及考试乃至实际应用中都常常涉及到这个问题。一般说来,当强调动作承受者,不必说出执行者或含糊不清的执行者时,多用被动式。须注意的是,许多地方与汉语不同。注意那些汉语中没有"被……"的意思,英语却应该用被动态。还要注意,英语的被动态往往由"by"引出,而有用介词"by"的短语往往又不是被动态,而是系表结构。还有些特殊现象,如:known to man(人类......所知),on foot步行(美国人有时用by foot),in carraige(乘四轮马车)等等。还有主动,真被动的十几个常用词的用法,以及so hey to carry而不用so hey to be carried 等习惯用法。有关这类情况,做到心中有数对全面掌握被动态,准确无误地解答习题非常关键,被动态必须涉及的是动词的各种时态变化的问题。英语的时态本来很复杂,怎样记住各自的被动形式呢? 首先要明确"将来进行无被动,现在完成进行同"。这两种时态无被动形式。

另外,不及物动词带有同源宾语的动词,反身代词的动词和系动词都无被动形式。即便如此,还有不定式,动名词,分词,以及它们的复合结构)的被动态,再加上情态动词,助动词以及它们的疑问式和否定式从中掺杂,真是令人头痛,眼花缭乱。下面口诀就以动词do为例,即do did过去式done过去分词,以口诀形式总结各种时态的被动态,一定对你有所启示。

[编辑本段]虚拟语气

语气是一种动词形式,用以表示说话者的意图或态度。虚拟语气表示所说的话只是一种主观的愿望、设或建议等。虚拟语气可以用在非真实条件句、主语从句、宾语从句、表语从句、同位语从句和定语从句中。本单元要求学员掌握虚拟语气的基本形式和用法;掌握情态动词用于虚拟语气;了解含蓄条件句;掌握虚拟时态与谓语动词时态的关系等。

[编辑本段]基本句型结构

句子按其结构可分为简单句、并列句和复合句。

一、简单句:

基本形式:简单句的基本形式是由一个主语加一个谓语构成。其它各种句子形式都是由此句型发展而来,如基本句型:

1.主语+谓语:

这种句型简称为主谓结构,其谓语一般都是不及物动词,例:

Things change.事物是变化的。

Nobody went.没有人去。

--Did you go by sea?你们走的是海路吗?

--NO,we flew.不,我们是飞去。

2.主语+连系动词+表语:

这种句型称为主系表结构,其实连系动词在形式上也是一种谓语动词,但实质上表语成了谓语,例:

Mr. Turner is an artist.特纳先生是位画家。

The milk turned sour.牛奶变酸了。

She became a lawyer.她当了律师。

3.主语+谓语+宾语:

这种句型可称为主谓宾结构,它的谓语一般多是及物动词,例:

We nr beat children.我们从来不打孩子。

My sister will fix rything.我姐姐会料理一切。

4.主语+谓语+宾语+宾语:

这种句型可称为主谓宾宾结构,其谓语应是可有双宾语的及物动词,两个宾语一个是间接宾语,一个是直接宾语,例:

He ge the book to his sister.他把这本书给了他的妹妹。

I'll write you a long letter.我将写给你一封长信。

5.主语+谓语+宾语+宾补:

这种句型可简称为主谓宾补结构,其补语是宾语补语,与宾语一起即构成复合宾语,例:

I found the book easy.我发现这本书不难。(形容词easy作补语)

I'll let him go.我将让他去。(不定式go用作补语)

注意:有时两个或更多的并列主语拥有一个共同的谓语,甚至并列有两个主语和两个谓语,这样的句子仍然是简单句,例:

China and other countries in the east Asia are dloping rapidly.和东亚其它正在迅速地发展。(China and other countries并列主语)

Mr. Wang and I often work toger and each other.王先生和我常在一起工作互相帮助。

It 结构:

It 既是代词又是引词。作代词时,它可作人称代词、指示代词、非人称代词,用于前指、非确指或习语中。作引词时,它本身无实义,只起先行的作用。可作形式主语或形式宾语,真实地主语或宾语是不定式、动名词或名词从句,它们则放在后面。It 也用于强调句结构。如想强调某个词或部分,可用it is (was)+强调部分(主语、宾语或状语)+that(who)…的强调结构。本章要求了解代词 it 和引词it 的各种用法,重点掌握it 用于前指或后指;引词it 用于强调结构。

二、并列句:

两个或两个以上的简单句用并列连词连在一起构成的句子,叫做并列句,其基本结构是“简单句+并列连词+简单句”。并列连词有:and, but, or, so等。并列句是由两个或两个以上的简单句连接而成。并列句中的各简单句意义同等重要,相互之间没有从属关系,是平行并列的关系。它们之间用连词连结。

三、复合句:

复合句(Complex Sentence)由一个主句(Principal Clause)和一个或一个以上的从句(Subordinate Clause)构成。

主句是全句的主体,通常可以存在;从句则是一个句子成分,不能存在。

从句不能单独成句,但它也有主语部分和谓语部分,就像一个句子一样。所不同在于,从句须由一个关联词(connective)。

1、名词性从句:

在句子中起名词作用的句子叫名词性从句 (Noun Clauses)。 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能,名词性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。

1)主语语从句:

作句子主语的从句叫主语从句。主语从句通常由从属连词that,wher,if和连接代词what,who,which,whatr,whor以及连接副词how,when,where,why等词。that在句中无词义,只起连接作用;连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用,在从句中充当从句的成分。例如:

What he wants to l us is not clear. 他要跟我们说什么,还不清楚。

Who will win the match is still unknown. 谁能赢得这场比赛还不得而知。

It is known to us how he became a writer. 我们都知道他是如何成为一名作家的。

Where the English ning will be held has not yet been announced. 英语晚会将在哪里举行,还没有宣布。

有时为避免句子头重脚轻,常用形式主语it代替主语从句作形式主语放于句首,而把主语从句置于句末。主语从句后的谓语动词一般用单数形式。常用句型如下:

(1) It + be + 名词 + that从句

(2)It + be + 形容词 + that从句

(3)It + be + 动词的过去分词 + that从句

(4)It + 不及物动词 + that 从句

另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时,谓语动词要用虚拟语气“(should) +do”,常用的句型有:

It is necessary (important, natural, strange, etc.) that …

It is suggested (requested, proed, desired, etc.) that…

2)宾语从句:

名词句用作宾语的从句叫宾语从句。宾语从句的关联词与主语从句表语从句的关联词大致一样,在句中可以作谓语动词或介词及非谓语动词的宾语。

1. 由连接词that的宾语从句

由连接词that宾语从句时,that在句中不担任任何成分,在口语或非正式的文体中常被省去,但如从句是并列句时,第二个分句前的that不可省。例如:

He has told me that he will go to Shanghai tomorrow. 他已经告诉我他明天要去上海。

We must nr think (that) we are good in rything while others are good in nothing. 我们决不能认为自己什么都好,别人什么都不好。

注意:在demand、order、suggest、decide、insist, desire, request, command, doubt等表示要求、命令、建议、决定等意义的动词后,宾语从句常用“(should)+ 动词原形”。例如:

I insist that she (should) do her work alone. 我坚持要她自己工作。

The commander ordered that troops (should) set off at once. 司令员命令部队马上出发。

2. 用who,whom, which, whose, what, when, where, why, how, whor, whatr, whichr等关联词的宾语从句相当于特殊疑问句,应注意句子语序要用陈述语序。例如:

I want to know what he has told you. 我想知道他告诉了你什么。

She always thinks of how she can work well. 她总是在想怎样能把工作做好。

She will give whor needs a warm support. 凡需要帮助的人,她都会给予热情的支持。

3. 用wher或if的宾语从句,其主语和谓语的顺序也不能颠倒,仍保持陈述句语序。此外,wher与if 在作“是否”的意思讲时在下列情况下一般只能用wher,不用if:

a. 主语从句并在句首时;b. 表语从句时;c . 从句作介词宾语时;d. 从句后有“or not”时;e. 后接动词不定式时。例如:

Wher there is life on the moon is an interesting question. 月球上有没有生命是个有趣的问题。

The question is wher she should he a low opinion of the test?现在的问题是她是否应该有一个低意见的测试?

Everything depends on wher we he enough money. 一切要看我们是否有足够的钱。

I wonder wher he will come or not. 我想知道他来还是不来。

Can you l me wher to go or to stay? 你能否告诉我是去还是留?

4. 注意宾语从句中的时态呼应,当主句动词是现在时,从句根据自身的句子情况,而使用

不同时态。例如:

he studies English ry day. (从句用一般现在时)

he studied English last term. (从句用一般过去时)

I know (that) he will study English next year. (从句用一般将来时)

he has studied English since 1998. (从句用现在完成时)

当主句动词是过去时态(could, would除外),从句则要用相应的过去时态,如一般过去时,过去进行时,过去将来时等;当从句表示的是客观真理,科学原理,自然现象,则从句仍用现在时态。例如:

The teacher told us that Tom had left us for America.

5. think, beli, imagine, supe等等动词引起的否定性宾语从句中,要把上述主句中的动词变为否定式。即将从句中的否定形式移到主句中。例如:

We don’t think you are here. 我们认为你不在这。

I don’t beli he will do so. 我相信他不会这样做。

在句中作表语的从句叫表语从句。表语从句的关联词与主语从句的关联词大致一样,表语从句位于连系动词后,有时用as if。其基本结构为:主语 + 系动词 + that从句。例如:

The fact is that we he lost the . 事实是我们已经输了这场比赛。

That’s just what I want. 这正是我想要的。

This is where our problem lies. 这就是我们的问题所在。

That is why he didn’t come to the meeting. 那就是他为什么不到会的原因。

It looks as if it is going to rain. 看上去天要下雨了。

需要注意的,当主语是reason时,表语从句要用that而不是because。例如:

The reason why he was late was that he missed the train by one minute this morning .

【注意】wher 可表语从句,但与之同义的if却通常不用于表语从句。

2L的我粘贴了点。他那的有好多的都是语法专业用词,对中考没啥作用些的。

1. 1名词

名词可以分为专有名词(Proper Nouns)和普通名词 (Common Nouns),专有名词是某个(些)人,地方,机构等专有的名称,如Beijing,China等。普通名词是一类人或东西或是一个抽象概念的名词,如:book,sadness等。普通名词又可分为下面四类:

2)集体名词(Collective Nouns):表示若干个个体组成的体,如:family。

3)物质名词(Material Nouns):表示无法分为个体的实物,如:air。

4)抽象名词(Abstract Nouns):表示动作、状态、品质、感情等抽象概念,如:work。

个体名词和集体名词可以用数目来计算,称为可数名词(Countable Nouns),物质名词和抽象名词一般无法用数目计算,称为不可数名词(Uncountable Nouns)。归纳一下,名词的分类可以下图表示:

_______________________________________

| |专有名词 | |

| 名 | | 个体名词 | |

| | | | 可数名词 |

| | | 集体名词 | |

| |普通名词 | | |

| 词 | | 物质名词 | |

| | | | 不可数名词|

| | | 抽象名词 | |

1.2 其它名词复数的规则变化

1) 以y结尾的专有名词,或元音字母+y 结尾的名词变复数时,直接加s变复数:

如: two Marys the Henrys

monkey---monkeys holiday---holidays

比较: 层楼:storey ---storeys story---stories

2) 以o 结尾的名词,变复数时:

a. 加s,如: photo---photos piano---pianos

1.3 名词复数的不规则变化

1)child---children foot---feet tooth---te

mouse---m man---men woman---women

注意:与 man 和 woman构成的合成词,其复数形式也是 -men 和-women。

如: an Englishman,two Englishmen. 但German不是合成词,故复数形式为Germans;Bowman是姓,其复数是the Bowmans。

2)单复同形 如:

deer,sheep,fish,Chinese,Japanese

li,jin,yuan,two li,three mu,four jin

但除元、角、分外,美元、英镑、法郎等都有复数形式。如:

a dollar, two dollars; a meter, two meters

3)集体名词,以单数形式出现,但实为复数。

如: people pol cattle 等本身就是复数,不能说 a people,a pol,a cattle,但可以说

a person,a polman,a head of cattle,the English,the British,the French,the Chinese,the Japanese,the Swiss 等名词,表示国民总称时,作复数用。

如: The Chinese are industries and bre. 是勤劳勇敢的。

4)以s结尾,仍为单数的名词,如:

a. maths,politics,physics等学科名词,为不可数名词,是单数。

b. news 是不可数名词。

c. the United States,the United Nations 应视为单数。

d. 以复数形式出现的书名,剧名,报纸,杂志名,也可视为单数。

"The Arabian Nights" is a very interesting story-book.

<<一千零一夜>>是一本非常有趣的故事书。

5) 表示由两部分构成的东西,如:glasses () trousers, clothes

若表达具体数目,要借助数量词 pair(对,双); suit(套); a pair of glasses; two pairs of trousers

6) 另外还有一些名词,其复数形式有时可表示特别意思,如:goods货物,waters水域,fishes(各种)鱼

1.4 不可数名词量的表示

1)物质名词

a. 当物质名词转化为个体名词时。

比较: Cake is a kind of food. 蛋糕是一种食物。 (不可数)

These cakes are sweet. 这些蛋糕很好吃。 (可数)

b. 当物质名词表示该物质的种类时,名词可数。

We need various steels. (可数)

c. 当物质名词表示份数时,可数。

1.7 名词的格

在英语中有些名词可以加"'s"来表示所有关系,带这种词尾的名词形式称为该名词的所有格,如:a teacher's book。名词所有格的规则如下:

1) 单数名词词尾加"'s",复数名词词尾没有s,也要加"'s",如the boy's bag 男孩的书包,men's room 男厕所。

2) 若名词已有复数词尾-s ,只加"'",如:the workers' struggle 工人的斗争。

3) 凡不能加"'s"的名词,都可以用"名词+of +名词"的结构来表示所有关系,如:the title of the song 歌的名字。

4) 在表示店铺或教堂的名字或某人的家时,名词所有格的后面常常不出现它所修饰的名词,如:the barber's 理发店。

如:John's and Mary's room(两间) John and Mary's room(一间)

6) 复合名词或短语,'s 加在一个词的词尾。

如:a month or two's absence

2. 冠词和数词

2.1 不定冠词的用法

冠词是虚词,本身不能单独使用,也没有词义,它用在名词的前面,帮助指明名词的含义。英语中的冠词有三种,一种是定冠词(the Definite Article),另一种是不定冠词(the Indefinite Article),还有一种是零冠词(Zero Article)。

2.6 数词

表示数目多少或顺序多少的词叫数词,数词分为基数词和序数词。表示数目多少的数词叫基数词;表示顺序的数词叫序数词。

一、基数词

1)基数词写法和读法: 345 three dred and forty-five;

2)基数词一般是单数形式,但下列情况,常用复数:

a. 与of 短语连用,表示概数,不能与具体数目连 用,如scores of people 指许多人;

b. 在一些表示"一排"或"一组"的词组里;

如:They arrived in twos and threes. 他们三三两两的到达了。

c. 表示"几十岁";

d. 表示"年代",用 in +the +数词复数;

二、序数词

序数词的缩写形式: first---1st second---2nd thirty-first---31st

三、 数词的用法

1)倍数表示法

a. 主语+谓语+倍数(或分数)+ as + adj. + as

I he three times as many as you. 我有你三倍那么多。

b. 主语+谓语+倍数(分数)+ the size (amount,length…) of…

The earth is 49 times the size of the moon. 地球是月球的49倍。

c. 主语+谓语+倍数(分数)+ 形容词(副词)比较级+ than…

The grain output is 8 percent higher this year than that of last year.

今年比去年粮食产量增加8%。

d. 还可以用by+倍数,表示增加多少倍

The production of grain has been increased by four times this year.

今年粮食产量增加了4倍。

2)分数表示法

构成:基数词代表分子,序数词代表分母。分子大于1时,分子的序数词用单数,分母序数词用复数:

1/3 one-third ; 3/37 three and three-snths.
