++++++++++++++++++++++++++++++++++++++名词与代词

名词可分为专有名词和普通名词两类。而普通名词又可分为个体名词、集体名词、物质名词和抽象名词。其中，个体名词和集体名词为可数名词，而物质名词和抽象名词为不可数名词。名词的复数构成通常是在其后加-s，但以-s，-x，-ch，-sh和大部分以o结尾的名词后加-es;以“辅音字母+y”结尾的名词把“y”变成“i”，再加-es。有些名词的复数构成是不规则的，有其特殊形式。有些名词在不同的情况下，属不同的名词词类，因此有时为可数，有时则为不可数。名词的格可分为主格(作主语)，宾格(作宾语)和所有格(表示所有关系)。代词可分为人称代词，物主代词，反身代词，相互代词，不定代词，指示代词，关系代词，连接代词和疑问代词等九类。

形容词与副词

形容词相副词在语法结构上都有比较级和最高级，它们的构成方法基本上一样，都与音节多少有关，有些形容词相副词有特殊的比较级和最高级形式。二者基本分为同级比较、比较级和最高级三种形式。

1.形容词与副词的用法

形容词中有词形相近的，也有词义相近的，应注意区别。如:

l)behind(在后的)--hind(后部的)，considerate(周到的，体贴的)--considerable(应考虑的)，eminent(闻名的)--imminent(紧迫的)，gracious(亲切的)--graceful(优雅的)，live(有生命的)--aIive(活的)，industrious(勤劳的)--industriaI(工业的)，like(同样的)--alike(同样的，仅作表语)，opposite(相对的)--opposing(反对的)，perspective(透视的)--respective(各自的)，sensitive(伤感的)--sensible(明显的)，etc。例如:

As anyone knows that we use our front teeth for biting and our hind teeth for chewing.

It's a considerable success for him.

2)elemental(初步的)--fundamental(基本的),eligible(合格的)--capable(能干的)

flexible(灵活的)--changeable(可改变的)，initial(最初的)--preliminary(初步的，预备的)，slack(松弛的)--lazy(懒惰的)，vaIueless(无价值的)--priceless(无价的)，vivid(生动的)--living(活的)，etc。例如:

Henry's speech was so vivid that his audience applauded again and again.

It is easier adapt to new situaions if one has a flexible attitude.We have finished the preliminary exam .

Your suggestion is priceless，and I will consider it carefully.

3)有些词尾为-ly 的并非副词，而是形容词,如:lovely，likdy，deadly，earthly(现世的)，

leisudy(空闲的)，weekly，yearly，manly(丈夫气概的)，brotherly，frendly等。例如:

What a lovely girl Jenny is always ready tO help OtherS.

China Daily is of course a daily newspaper but not a weekly one.He is a very friendly young man.As he didn't have any experience，he was likely to have problems.

以下情况形容词常用于后置:1)形容词短语，即形容词十副词，介词短语或不定式。2)一些表语性形容词要后置，如:present，available，involved，concerned，etc。3)形容词修饰不定代词something，anything，everything 时要后置。例如:

There was something nice about my feeling that she knew aIl.

For this reason，as well as the additional cost involved，flow force compensation is generally not desirable.

I came across another question hard to answer then.

I wondered if there was a room available.

副词的位置为:修饰哪个词就放在哪个词前面;放在系动词和助动词之后，行为动词和分词之前。例如:

The old law were instituted tO protect the long negleCted rlghts of children.

I can hardly believe that he is the murderer.

Although he has advantages，lt is still too early to say that he is sure to win.

2.比较级与最高级的基本形式和用法

形容词的比较级和最高级的构成为:单音节词一般在词尾加-er和-est。如果以-e结尾，仅加-r和-st;如末尾仅有一个辅音字母，须双写词尾再加-er和-est;如果以y 结尾的，把y 变i，加-er，-est;多音节单词和双音节词(其中包括由分词和分词演变而来的形容词，如:known，worn，wounded，shocking，striking，interesting，ect.则在其前加more和most;有些形容词的比较级和最高级是不规则的，如:good(well)-better-best，bad(ill)-worse-worst，many(much)-more-most，little-less-least，far-farthe(further)-farthest(furthest)。有些形容词没有比较级形式，如:absolute，chief，entire，eternal，excellent，fatal，final，foremost，inevitable，infinite，main，naked，perfect，possible，primary，right，sufficient，supreme，universal，utter，vital，whole，wooden，ect。例如:

Mary is the best student in the class.

Further negotiation will be conducted next month.

The food we have is sufficient.

Needless to say，he is stronger than his opponent.

一般副词的比较级和最高级与形容词一样，单音节的以在词尾加-er和-est构成，多音节的以加more 和most的方法构成;有些比较特殊,如：well-better-best，badly-worse-worst，much-more-most，little-less-least。以-ly结尾的副词，在其前面加more，most。例如:

Tonny runs more han any other students in the class.

Which do you like best，Thorn Birds，Gone With the wind or great expectation?

I prefer less sugar in the miIk.

She get more income every month than her husband.

形容词和副词的原级比较由“as +形容词或副词(或后跟名词或短语)+as”构成，“as-as“前可加not，just，almost，nearly，quite，twice，several times等词修饰。否定式中not后面的as可改为so。例如:”

Running forfifteen minuteswillburn a$m&ny caZorieso$walking forthirty minut笆·

Henan Province is several times as large as shanghai.

Jimmy has as nervers a way of speaking as his father.

Getting rid of a bad habit isn't so simple as taking it up.

形容词相副词的比较级形式为:“形容词(副词)比较级+than+-”，应注意than前后相比较的人或物要一致。比较级前可以跟evm ，much，stilI等副词修饰比较级，表示强调。例如:

Mother worried much more about my younger brother than she did about me.

Sound travels faster through water than through air.

The economic development in south China is faster than that in North China .

My books are much more than Li ping's.

形容词相副词的最高级的形式分别为:“the+形容词最高级+名词十范围表达”和“副词最高级十名词+范围表达”，副词的比较级和最高级不需要加the。例如:

Our foreign exchange reserve didn't decline despite the worst flood in sixty years.

I finished the work more successfully than he had expected.

应注意以下表达式的含义:the same as(和……一样)，no less than(不少于)，not less than(只有)，had better(最好)，less than(不到)，more or less(或多或少)，other than(除了)，rather than(而不是)，the more…the more/less(越……就越……)例如:I am sure that the amount of money used in repaying a loan would have the

same value as the amount of money borrowed.

时态与语态

1.时态

现在完居时表示过去某时开始的一个动作或状态一直延续到现在，表示现刻以前发生的动作或情况。常用状语just,since,for,already,yet,ever,never,often,

several times,lately,recently,during the last week,so far,up to now(the present)等，由since引起短语（或从句）的句子里，主句的谓语应用完成时；若since引起一个从句，从句谓语可用过去时（表示行为的起点）。只有在“it is ……since”的句型中，主句才可用也可不能完成时。例如：

Japanese is certainly difficult for me as I have never learned it before.

We are living a hard life because Father has been unemployed for half a year.

I have planted thirty trees since I moved here.

现在完成时与过去时的比较：现在完成时表示某一动作一直延续到现在或已经完成，强调结果；而过去时表示发

生在过去的动作，强调过去的动作。例如：

he has read the book for two hours.(强调动作的持续)

He has read the book。（强调动作的完成）

He read the book last night.（强调过去的动作，有过去时间状语）

过去完成时表示在过去某一时刻或某一动作之前已完成的动作。例如：

I still remember last summer vacation spent in Paris.That was the first time I had ever been to Europe.

Since be had eaten before he came to the party,he refused the kostess'offer of a cake.

将来完成时表示将来某一时间之前已经完成的动作，分为一般将来完成时和过去将来完成时。常用by the time,at the end of 来引起。例如：

The debate will have begun by the time our English teacher arrives.

Tonny bad thought the train would have left by the time he got to the station.

At the end of next month,I will bave finished this work.

现在完成进行时强调过去发生的动作一直延续到说话时刚结束，或动作仍在进行中。过去完成进行时表示运作延续到某一时间刚结束，或仍在进行。例如：

Eventually,I received the letter that I had been expecting for a long time.

When she retires,Mrs.Jones will have been teaching here for over thirty years,but her classes are never dull.

2.语态

英语分为主动词态和被动词态。主动语态是指句中的主语是动作的执行者，而被动语态的主语是动作的承受者。英语中只有及物动词、动词短词和某些成语才能构成被动语态。被动语态的构成形式为“be+动词的-ed分词”。另外，“be+get+动词-ed分词”是特殊形式。

1）动词的被动语态有以下几种时态的变化（以find为例：）

现在时：is (are)found

将来时：shall (will)be found

现在进行时：is (are)being found

现在完成时：have (has)been found

将来完成时：shall (will)have been found

过去时：was (were)found

过去将来时：should (would)be found

过去进行时：was (were)being found

过去完成时：bad been found

过去将来完成时：should (would)have been found

例如：

Mineral water has been regarded by all people as a healthy drink.

The program bad been conducted in both the United States and Europe well before 1900.

2）能作及物动词的短语动词也可用被动态，应注意其固定搭配。例如：

The problem will be taken care of as soon as possible.

Although the mission was to be kept a secret,it was revealed to the press

3）表示状态或特征的及物动词，如:contain,cost,fit,have,lack,suit等；不及物动词及动词短语，如：result from,belong to,consist of 等，不能用被动态。例如：

The magazine that I bought the day before yesterday costs me twenty and a half yuan.

Some critics maintain that when a work of literature lacks reference to the general experience of mankind,it fails as art.

从句

从句分为定语从句，状语从句和句词从句三大类。定语从句又分为限定性和非限定性从句两种，由关系代词或关系副词引导，修饰主句的某个成分。状语从句分为时间、结果、让步原因、条件及行为方式状语从句。名词从句包括主语、宾语、表语和同位语从句及there be 句型。

1.定语从句

限定性定语从句中that可代表人和事，而which只代表事；二者在从句中作主语或宾语。that作宾语时常可省略，which则不能，而且其后的“不及物动词+介词”中的介词不能省略。which作宾语时，先行词与which之间的介词不能省。例如：

The first doll that could say “mama”was invented in 1830.

The second half of his voyage was buy fay the more dangerous part,during which he sailed round the Cape Horn.

代表all,anything,something,nothing,much等词时，用that而不用which，that作宾语可省略。例如：

I care anything that has something do with it.

You'd better do something he prefers to do to please him.

That is the last time we met each other.

I came across the woman you told me about yesterday.

who和whom引导的从句用来修饰人，分别作从句的语词和宾语。where是关系副词，用于表示地点的定语从句，而when用来表示时间。whose是关系代词，修饰名词作定语。例如：

Heney Ford is the person who is most responsible for developing the idea of mass production.

The knee is the joint where the thigh bone meets the large bone of the lower leg.

The next morning when she came down to breakfast,Mary was beaming with the pleasure of a new,great discovery.

The visiting professor is a famous scientist whose son studies in my dapartment.

在下列情况，限定性定语从句的关系代词可以省略；1）当关系代词在从句中作宾语或表语；或它们在从句中作介词的宾词，而该介词又在句末时；2）当先行词是that,all,only,everything,something,nothing等代词时，或先行词前有一个最高级开容词修饰时；3）当先行词前有only,any,all,first,no,last等修饰时，或先行词就是time,moment,way(any-way)direction,distance等名词时，关系代词即可省略。例如：

The delegationg we has been waiting for finally arrived

I met the woman you told me about.

She gave me all she could afford.

With TV we can see things happen almost at the exact moment they are happening.

非限定性定语从句，其作用为：对所修饰的成分作进一步的说明，它与主句用逗号隔开。此类从句省略后其余部分仍可成立。在非限定性定语从句中，which可代表前面的整个句子；代表人时只能用who,whom,而不能用that;as也可用作关系代词。例如：

The telephone,as we know,was the invention of alexander Graham Bell.

The Little White Hounse in Warm Springs was the Georgia home of President Franklin D.Roosevelt,who died there on April 12,1945.

living in a damp house for a long time is harmful to one's health,which is known to everyone.

2.状语从句

状语从句可分为：时间状语从句（主要由when,whenever,after,before,as,since,once,as soon as,until,while）

so……that such……that

将语从句的中“主语+be”可以省略，前提是，从句主语和主句主语一致，且从句谓语“be”省略后的结构为“连词+现在分词/过去分词/介词短词/形容词/名词短语”。例如：

When well fitted glasses can correct most sight defects in healthy eyes.

If necessary,I would like to see you in your office.

Although seriously wounded,he never complained

3.名词从句

名词从名包括主语从句、宾语从句，其中有介词与形容词的宾语从句、表语从句同位语从句。

she was surprised how simple his problem was.

3）表语从句

表语从句对主语的内容起解释和阐述的作用；若表语从句用that引起，that起连接作用，不能省略。表语从句也可用连接词how,when,where,why,what引起。由

because引起的表语从句通常只用在“this/that/it is because”结构中。例如：

动词不定式

1.不定式的基本形式与结构

动词不定式指通常由to加上动词原形（如ro write）所构成的一种非限定性动词形式，但在有些情况下to可以省略。动词不定式有进行体和完成体（如to be writing,to have written）也有被动态（如to be write），所有的主动词，不论是及物动词还是不及物动词，也不论是动作动词还是状态动词，都有不定式形态。助动词除be和have外，没有不定式形式。动词不定式在语法功能上可作主语、宾语、表语、定语和状语。

2.不定式的用法

1）不定式结构作主语

To get contact with family in Taiwan nade him extremely happy since they separated more than 40 years ago.

To finish that task im such a short time is really a challenge.

在上述情况下，如果不定式较长，显得头重脚轻，则可由代词it作形式主语（形式主语it不可由that或this 等其他代词代替），而将不定式放在后面。如：

It made him extremaly happy to get contact with his family in Taiwan since they separated more than 40 years ago.

John admitted that it is always difficult for him to be on time.

不定式结构所表示的动作是谁做的，即不定式的逻辑主语，通常可以通过for sb.to do sth.结构表达。

It is quite important for us to read good books during a general review.

It is not diffcult for those talented students to pass the exam.

在某些形容词（如：careless,clever,considerate,foolish,good,impolite,

kind,naughty,nice,silly,stupid等）作表语时，不定式后可以加of来引导出其逻辑主语：

It is very kind of you to tell me the truth.

It is stupid of him to do such a silly thing.

2）不定式作宾语

不定式作宾语有两种：一种是及物动词后直接跟带to的不定式，另一种是“及物动词+疑问句+带to 的不定式”。

及物动词+带to的不定式结构：

只能跟动词不定式的动词，常见的有：afford,agree,aim,appear,ask,helieve,

care,claim,decide,demand,desire,determine,expect,fail,happen,hesitate,hope,intend,learn,long,manage,offer,pretend,promise,pre pare,refuse,seek,sweat,undertake,want,wish等。

He managed to solve the complicated problem

The stranger offered to show ne the way.

Mr.Smith undertook to build a new plant in South Africa.

动词+疑问代（副）词+不定式：

这类动词常见的有：advise,decide,discuss,find out,forget,imquire,know,learn,regard,remember,see,teach,tell,understand,wonder等。常用的疑问代（副）词有what,when,where,which,how,whether等，但不包括why。

He does not know when to start.

You can decide whether to continue or to stop.

I will show you how to deal with it.

有时，不定式可由it代替，而把不定式放到后面去。这可以用这一结构表达：动词（如find,think,consider,feel等）+it+形容词+不定式。

She considers it necessary to make friends with them.

We find it diffcult to finish all the homework before 9 o'clock.

3）不定式作表语

一般情况为主语是不定式（表示条件），表词也是不定式（表示结果）：

To see is to believe.

To work means to earn a living.

另一种情况为主语是aim,duty,hope,idea,job,plan,problem,purpose,thing,

wish等名词为中心的短语，或以what引导的名词性从句，不定式表语对主语起补充说明作用：

His aim is to study abroad in the near future.

The most important thing is to negotiate with them about the proce.

What I want to say is to forget all the unhappy experience.

4）不定式作定语

不定式结构作名词词组修饰语主要有三种类型：

第一种，被修饰的名词词组是不定式的逻辑宾语。例如：

There was really nothing fo fear.

He gave me an interesting book to read.

如果不定式是不及物动词，后面就得加相应的介词。例如：

Mary needs a friend to play with.

That girl bas nothing to worry about.

They have a strict teacher to losten to.

Although the film had been on for ten minutes,I still was not able to find a chair to sit on.

第二种，被修饰的名词词组是不定式的逻辑主语。例如：

Have you got a key to unlock door?

The action to be taken is correct.

There is nothing to be gained by pretending.

第三种，被修饰的名词词组是不定式的同位结构。这类名词通常是表示企图、努力、倾向、目的、愿望、打算、能力、意向等意义的名词，如ability,attempt,

frrort,impulse,inclination,wish等。例如：

Her daughter will make an even bigger effort to please her.

I have no wish to quarrel with you.

Neither of them had any inclination to do business with Mary.

（5）不定式作状语

不定式结构在句中作状语通常都能转换为限制性状语从句。例如作原因状语：

They are quite surprised to see the great changes taking place in the area.

=They are quite surprised hecause they see the great changes taking place in the area.

He was lucky to arrive before dark.

作目的状语：

She raised her voice to be heard better.

=She raised her voice so that she could be heard better.

We went via Heidelberg to miss the fraffic jam.

=We went via Heidelberg so that we could miss the fraffic jam.

作结果状语：

The French football team played so successfully that they even defeated the Brazilians.

He got to the station only to be told the train had gone.

=He got to the station and was told that the train had gone.

3.不带to的不定式的使用

动词不定式通常带to，但有些搭配中不带to，在另一些搭配中可带to可不带to。归纳起来，以下情况下使用不带to不定式：

1）在can/could,may/might,will/would,shall/should,must,need,dare等情态动词之后，动词不定式不带to。

2）在表示感觉意义的动词，如see,feel,watch,notice,smell,hear,observe等后，或是表示“致使”意义的动词，如have,let,make等后，动词不定式不带to。例如：I often heard him say that he would study hard.

I must have him see his own mistakes.

但是，当这类结构转移为被动语态时，后面的不带to不定式一般转换为带to 不定式。

例如：

He was often heard to say that be would study hard.

After he had finished wpeaking,he was made to answer innumerable

questions.

3）在动词help之后可用不带to和不定式，也可用带to 的不定式。例如：

help the old lady(to)carry the heavy box.

4）在had better,would rather,may/might as well,rather than,cannot but等搭配之后，动词不定式也不带to 。例如：Unless you feel too ill to go out,I would rather not stay at home tonight.

She could not but criticize his foolish behaviour.

5）在make do,make believe,let drop,let fall,let fly,let slip,let drive,

let go off,hear,say,hear tell,leave go of等固定搭配中，用不带to的动词还下式。例如：

They let go of the rope。他们松开了绳子。

john let fly a torrent of abuse at me。约翰朝我痛骂了一顿。

I've heard tell of him。我听说过他。

Some of the faculty were ley go for lack of the students.由于生源不足，一些教职员工被解雇了。

6）在介词bt,except之后，如果其前有动词do的某种形式，其后不定式一般不带to，反之则必须带to，表示“不得不，只能”。例如：

He will do anything except work on the farm.

There was nothing left for the enemy to do but surrender.

The spy was both hungry and cold;there was nothing left for him but to give in.

I had no shoice but to wait till it stopped raining.

下面一些短语是固定搭配，不带to：

can not help but,can not choose but,can not but,do nothing but,have nothing to do but。例如：

I can not but admire his courage.

如果上述句中有do，to省略：

I did nothing but watch TV last night.

如果是下面一个固定搭配，就带to：

I have no choice but to give up my idea.

7）紧跟在why或why not之后的动词不定式总是不带to。但是，紧跟who,what,

which,whether等连接词后的不定式带to。例如：

Why stand up if you can sit down?

Why not ask your teacher when you don't understand the meaning?

You need'nt decide yet whether to study arts or science.

4.不定式的完成式和进行式

1）构成

完成式：to+have done

进行式：to+be doing

2）用法

完成式：如果不定式所表示的动作（状态）发生在主要谓语动作之前，那么不定式就要用其完成式。

进行式：如果主要谓语动作（情况）发生时，不定式所表示的动作正在发生，那么不定式就要用其进行式。例如：She feels relaxed to have finished writing her thesis before the deadline.

The Vikings are believed to have discovered America.

When you called me last night,I happened to be working on the computer.

5.不定式的被动形式

当不定式的逻辑主语是动作的承受者时，不定式要用被动形式，包括它的一般式和完成式。例如：

For twelve years,Spanish censorship did not allow Lorca's name to be mentioned and his work to be published.

The snow was supposed to have blown off the mountain.

6.不定式的否定形式

否定形式是在不定式的标志to前加not。例如：

I decided not to ask him again.

Please remember not to leave the lights on when are out.

动名词

1.动名词的形式

动名词是由动词原形+-ing构成（如writing)，有完成时态和被动语态（如having

written,being written)。

2.动名词的用法

动名词通常在句中作主语和宾语。

1）动名词作主语

Going to the college is the little boy's dream.

Keeping studying hard will make you pass the exam.

2）动名词作宾语

有些动词后面只能带动名词作宾语，不能带不定式作宾语。此类动词常见的有：admit,acknowledge,anticipate,appreciate,avoid,consider,contemplate,

defer,delay,deny,detest,dislike,ensure,enjoy,escape,excuse,evade,faciliate,fancy,favour,finish,forbid,imagine,include,keep,mind, miss,postpone,pactise,resent,resist,risk,suggest,quit,worth等。例如：

John was considering buting a new car.

I hope you didn't contemplate coming with us on this trip.

The witness denied having seen the accused man.

I would appreciate your keeping it a secret.

3)某些短语后面只能接动名词，不能接不定式。

此类短语常见的有：be(get)used to,be accustomed to,be dedicated to,be devoted to,be devoted to ,be busy,be committed to,be subject to,cannot help,cannot resist,cannot stand,confess to,feel like,give up,have trouble(in),have difficulty(in),have a good/hare time(in),have fun(in),have an objection to,it is no good/use,keep on,insist on,look forward to,object to ,pay attention to,put off,resort to,succeed in等。例如：

I cannot stand getting up early in the morning.

I have no difficulty(in)reaching the top of the mountain.

There is no use staying on.

I cannot resist(his)bargaining.

Although punctual himself,the professor was quite used to students'being late for his lecture.

4）动词或短语后面也可以接动名词的被动形式。用主动形式还是被动形式，要根据包子的意思而定。例如：Carlos just missed being caught.

That person wore dark glasses to avoid being recognized.

I object to being treated like a child.

3.另一类动词后面可以带动名词作宾语，也可以带不定式作宾语。这类动词又可以分为两种：

1）带动名词作宾语与带不定式作宾语而意义无多大区别的动词

a）在begin,cannotbear,cease,continue,dread,like,love,neglect,omit,

propose等动词之后，如表示一般的行为，用动名词作宾语为多；如表示特定的或具体的动作，则不定式结构作宾语为多。例如：

I don't like swimming.

I don't like to swim this afternoon.

John prefers doing it his way.

John prefers to go outing outing tomorrow.

b）在being,start等动词之后，如表示有意的动作，用动名词结构为多；如表示特定的或具体的动作，则用不定式结构作宾语为多。例如：

After some hesitation,be began speaking out his own opinion.

It has already begun to rain.

c）在attempt,intend,plan等动词之后，用不定式结构与动名词结构意义相同，但以用不定式较为常见。例如：He intended to buy a new car.

He intended travelling abroad next summer.

d）在encourage,permit,allow,recommend,advise,authorise等动词之后，一般用动名词作宾语，或者用不定式作宾语补足语。即：

encourage/permit/allow/recommend/advise/authorise+doing,encourage/permit/allow/recommend/advise/authorise+somebody+t o do

例如：

He advised going out for a walk.

he advised us to go out for a walk.

e）在agree,decide等动词之后，可以直接跟不定式结构，但如果跟动名词，则动词后必须加适当的介词。例如：He agreed to do me a favour.

=He agreed to do me a favour.

In the end the manager decided to double the advertising budget.

=In the end the manager decided on doubling the advertising budget.

f）在need,want,require,deserve等动词之后，可以用动名词的主动形式表示被动意义，这相当于不定式的被动形式。例如：

The house needs repairing.

=The house needs to be erpaired.

The disabled deserve respecting.

=The disabled decerve to be respected.

2）带动名词作宾语与带不定式作宾语而意义不同的动词

a）动词rememberm,forget后可以跟不定式或动名词，但意义有明显区别：跟动名词，其动作发生在“记得”或“忘记”的动作之前；跟不定式，其动作发生在“记得”或“忘记”的动作之后。试比较：

I remember posting this letter.我记得这封信已寄出了。

I remember to post this letter in the afternoon.我记得下午要将这封信寄走。

b）动词regret后可以跟不定式或动名词，但意义有明显区别：

regret doing:为做过的事感到抱歉

regret to do ：为即将要做的事感到抱歉

试比较：

I regret to say that I can not go with you after school.

I regret having criticised you seriously in class.

c）动词try,mean,cannot help,used to 后跟不定式还是动名词，取决于这些词本身的含义。例如：

You should try to answer the questions by yourself.(Try to do:试着做某事)

We try using this new method.(Try doing：试着做某事)

I meant to go to the exhibition but I forgot(mean to do：打算做某事)

Success neans working very,very hard.(mean doing:意味着做某事)

I can't help apologizing.(cannot help doing:忍不住做某事)

I can't help to apologize for him.(cannot help to do:不能帮助做某事)

Mr.Smith used to jog in the morning,but now he has stopped.(used to do:过去经常或总是干某事)

Inland canals are used to ship farm and factory goods to nearby towns.(be used to do:被用来干某事)

I am not used to getting up early in the morning.(be/get used to doing:惯于干某事)

d）动词stop,continue,go on,leave off 之后，通常用动名词结构作宾语，如果用不定式结构，则不是宾语而是目的状语，相当于in order to。试比较：

They stopped working。他们停止工作（来做其他事）。

They stopped to work。他们停止（帮其他事）来工作。

The students went on reciting the text.学生们继续背诵课文。

The students went on to recite the text.学生们停下其他事，继续背诵课文。

She left off doing the housework.她停止做家务（去干其他事）。

She left off to do the housework.她停止（干其他事）来做家务。

4.动名词的逻辑主语问题

动名词，顾名思义，具有名词的特点，即可以加物主代词和名词的属格来表示其逻辑主语（这时动名词的逻辑主语与句子主语不一致）。如果动名词的逻辑主语就是句子主语，则前面不用加物主代词或名词的属格。例如：The watchman reported finding the door open.

=The watchman reported that he had found the dor open.

此外，finding的主语与主句主语一致，都是the watchman，所以finding前不加物主代词。

I appreciated very much your helping me through the tough period.

此处，helping的主语是you ，而主语是I，两者不一致，所以helping前的物主代词your不能省略。

一般说来，能带动名词作宾语的动词都可以根据语义意图在动名词之前加上或略去逻辑主语。但有些动词，如excuse,forgive,pardon等，其后的动名词结构总是带有逻辑主语的。这些逻辑主语通常由名词或代词宾格表示，也可由名词属格或形容词性物主代词表示。例如：

I do mind people smoking in public places.（名词宾格作逻辑主语）

We don't understand him needing so much money.（代词宾格作逻辑主语）

I will never forgive his betraying me by breaking his promise.（物主代词作逻辑主语）

Mary excused the boy's upsetting the ink.（名词属格作逻辑主语）

分词

1.分词的形式

这里所讲的分词包括-ing分词和-ed分词，即传统意义上的现在分词和过去分词。现在分词由动词原形+-ing构成（如listening）；过去分词通常由动词原形+-ed构成（如listened），也有不规则形式（如go-gone）。现代英语的绝大多数都是规则动词，不规则的只是少数。

2.分词的基本用法

分词在句中通常可以用作表语、定语补语和状语。下面按照现在的分词和过去分词的用法分别作介绍。

现在分词的基本用法：

现在分词表示主动的意义；表示一般性的或正在进行的动作；在表面形式上有“一般式”和“完成式”与“主动式”和“被动式”之分。

1）作表语

现在分词作表语通常表示主语所具有的特征。例如：

This story quite interesting.

The journey without you will be boring.

2）作定语

现在分词可以单独作定语，也可以构成合成词作定语，但在更多的情况下是分词短语作定语，包括限定性和非限定性（用逗号与其他部分分开），在意义上相当于一个定语从句。现在分词作定语通常带有主动意义和未完成意义。例如：

The man following was obviously in a hurry。（现在分词单独作定语）

They acted just like a conquering army。（现在分词单独作定语）

Do you know the man standing over there by the motor car?（分词短语作限定性定语。）

Last night,we caught a thief stealing John's bike.（分词短语作限定性定语）

The name Nebraske comes from the Oto Indian word “ebrathka”.meaning flat water.（分词短语作非限定性定语）3）作宾语补足语

a.表示感觉和心理状态的动词，如hear,feel,find,listen to,look at,watch,

notice,observe,smell see等词的宾语可以用现在分词作宾语补足语。例如：

I noticed him slipping away before the end of the meeting.

I can smell turkey roasting,and it's making me hungry.

b.表示“致使”等意义的动词，如catch,get,have,leave,set等词的宾语可以用现在分词作宾语补足语。例如：

What A saw just now set me thinking of my shildhood in the countryside.

Please don't keep the machine running while you are away.

4）作状语

现在分词作状语表示主语在进行一动作的同时所进行的另一动作，它对谓语动词起修饰或陪衬的作用。这时要注意现在分词与其逻辑主语在时态和意义上的统一。例如：

Rushing out of the room,be has knocked down by a car.（作时间状语）

=When he rushed out of the room,he was hnocked down by a car.

Working harder,you will pass the entrance exam.（作条件状语）

=If you work harder,you will pass the entrance exam.

She sat at a window and read a book.（作伴随状语）

=She sat at a window and read a book.

Having won the championship,he was awarded a million dollars.（作原因状语）

=Because he had won the championship,he was awarded a million dollars.

Even if taking a taxi,I will still be late for the meeting.（作让步状语）

=Even if I take a taxi,I will still be late for the meeting.

The road is under construction,thus causing the delay.（作结果状语）

=The road is under construction,and thus caused the delay.

注意，当现在分词作让步状语时，一般放在句首，常常由although,though,even if ,unless等连词引入；作结果状语时，一般放在句末，前面可so,thus,hence，

thereby等副词。

过去分词的基本用法：

与现在分词不同，过去分词表示被动的意义，表示已经完成和被动的动作。在表现形式上，只有一种形式。

1）作表语

过去分词作表语表示主语所处的状态。用作表语的过去分词大多来自及物动词；不及物动词的过去分词能作表语的只限于少数表示位置转移的动词，如go,come,

assemble等，它们用在联系动词之后，表示完成意义，无被动意义。例如：

The man looked quite disappointed.

He is greatly discouraged by her refusal.

His hair is nearly all gone.

已经形容化了的过去分词大多可作表语，常见的有accomplished,amazed,amused,

astonished,broken,closed,completed,complicated,confused,crowded,devoted,disappointed,discouraged,drunk,excited,frightened, hurt,interested,lost,astisfied,surprised,worried等。

2）作定语

a）用作前置定语的过去分词通常来自及物动词，带有被动意义和完成意义。例如：

We like skating in the frozem lake in the winter.

=We like skating in the lake which has been frozen in the winter.

How many finished products have you got up to now?

=How many products that have been finished have you got up to now?

来自不及物动词的过去分词很少能单独用作前置定语，能作这样用的仅限以下几个词，这时仅表示完成意义，不表示被动意义：

a retired worker=a worker who has retired

an escaped prisoner=a prisoner who has escaped

a faded/withered flower=a flower that has faded/withered

fallen leaves=leaves that have fallen

the risen sun=the sun that has just risen

a returned student=a student who has returned

vanished treasure=treasure that has vanished

b)用作后置定语的过去分词通常也来自及物动词，表示被动意义和完成意义。这明相当于一个定语从句。例如：

Things seen are better than things heard.

=Things which are seen are better than things which are heard.

The lobster broiled over charcoal was delicious.

=The lobster which was broiled over charcoal was delicious.

3）作宾语补足语

a）see hear,feel,find,think等表示感觉和心理状态的动词可以带过去分词作宾

语补足语。例如：

Tom found himself involved in an awkward situation.

I saw Tom dressed like a beggar in the street.

Everybody thought the match lost until the last minute.

b）make,get,have,keep等表示“致使”意义的动词可以带过去分词作宾语补足语。

例如：

I have my chothes washed everyday.

Don't get your schedule changed;stay with us in the class.

He's trying to make himself understood.

Please keep us informed of the latest price.

c)like,want,wish,order等表示希望、要求、命令等意义的动词可以带过去分词作宾语补足语。例如：

We don't like such topics(to be)discussed in class.

I wish this problem(to be)solved this week.

4)作状语

用作状语的过去分词通常来自及物动词。过去分词用作状语时，修饰主句的谓语动词，意义上相当于状语从句，表示时间、条件、原因、伴随状况等。过去分词作状语，前边往往可以加when,while,if,as if,though。一般说来，这种结构的逻辑主语必须与主句的主语一致。例如：

Whenever praised,she blushes.（作时间状语）

=Whenever she is praised,she blushes.

United,we stand;divided,we fall.（作条件状语）

=If we are united,we stand;if we are divided,we fall.

Written in great haste,this book is full of errors.（作原因状语）

=Because this book in written in great haste,it is full of errors.

Mary was reading a love story,and was completely lost to the romantic life.（作让步状语）

=Mary was reading a love story,and was completely lost to the romantic life.

Although bron in Germany,John lives and works in U.S.A。（作让步状语）

=Although John was bron in Germany,he lives and works in U.S.A。

3.分词的完成式及被动式

前面提到过，过去分词只有一种形式，所以这里所讲的完成式及被动式均指现在分词的完成式及被动式。

如果现在分词表示的是一般性动作，不表明动作的先后或与谓语动作同时发生，这时要用现在分词的一般形式。例如：

Living in the downtown,we found a lot of amusements.

如果现在分词所表示的动作先于句子谓语发生，就要用现在分词的完成式“(not)having+过去分词”。例如：Having heard from my father,I was relieved.

Not having received any letter from my family,I was worried.

如果现在分词的逻辑主语是现在分词所表示的动作的对象，则要用现在分词的被动形式，包括其一般形式“（not）being+过去分词”和其完成形式“（not）having been+过去分词”。例如：

Upon being questioned,he denied having robbed the bank.

The new method,having been widely used abroad,can increase the working efficiency.

4.分词独立结构

如果过去分词或现在分词带有与句子主语不同的主语，这就构成了独立结构，也叫独立主格结构或垂悬结构，通常在句中起状语丛句的作用，表示原因、时间、条件、方式或伴随状况。

例如：

The holidays being over,they began to get down to do their work again.

（原因状语）

=As the holiday was over,they began to get down to do their work again.

All things considered,her paper is of greater value than yours.（条件状语）

=If all things are considered,her paper is of greater value than yours.

His homework done,Johan went out to play.（时间状语）

=After his homework had been done,Johan went out to play.

The girl was smiling sweetly,her long hair flowing hair flowing in the vreeze.（伴随状语）

当独立结构表示伴随状况时，可变为由with引导的介词词组，而表示否定意义的类似结构便可由without引导。例如上例可变为：

The girl was smiling sweetly with her long hair flowing in the breeze.

Without anyone noticing,I slipped out of the room.

独立结构的位置比较灵活，它可以置于句首、句中或句末。另外，独立结构中用作主语的名词之前的限定词有时可以省略。例如：

The manager sat quietly in his office,(his)eyes closed.

He stood in the doorway,(his)wet cloak dripping water on the rug,and waited for some sign of recogition.

前后呼应

1.主谓一致的基本原则：

主谓一致有以下三条原则：

1)语法一致原则，即在语法形式上取得一致。例如，主语是单数形式，谓语动词也采取单数形式；主语是复数形式，谓语动词也采取复数形式。

The students are very young.

This picture looks beautiful.

2)意义一致原则，即从意义着眼处理一致关系。例如，主语形式虽是单数但意义是复数，谓语动词也采取复数形式；而有些主语形式虽是复数但意义上看作单数，谓语动词也采取单数形式。

The prople in that country are fighting for independence.

The crowd deeply respect their leader.

Three years in a strange land seems a long time.

3)就近原则，即谓语动词的单数和复数形式取决于最靠近它的词语。例如：

Neither he nor I an going to see the film tonight because we are busy.

2.主谓一致的用法

根据以上三条原则，主谓一致有以下用法：

1)下列结构作主语，谓语动词一般用单数形式

a.表示时间、重量、长度、价值的名词作主语，谓语动词通常用单数形式。例如：

Two hundred miles is a long distance.

Ten dollars is a high price for that book.

b.由anyone,anything,anybody,no once,nothing,everyone,everybody

,everything,someone,somebody,each,either,neither Someone is knocking at

the door.

Anything is better than going to the movie tonight.

c.由“a series of,a kind of,a portion of+名词”作主语，谓语动词应用单数形式。例如：

A series of debates is scheduled to be held next week.

d.由“many a,more than one+单数名词”作主语，尽管意义上表示复数，但谓语动词仍采用单数形式。例如：

Many a person in these circumstances has hoped for a long break.

There is more than one answer to your question.

e.“名词+and +名词”作主语，表示同一人、同一概念或事物时，谓语动词用单数形式。例如：

A writer and educator is giving a lecture now.（这个人既是作家又是教育家）

f.“either(neither)+of+复数名词（或代词）”作主语，谓语动词用单数形式。例如：

If either of you takes a vacation now,we will not be able to finish the work.

Neither of them wants to come.

g.在each…and each…,every…and every…等结构之后，谓语动词用单数形式。例如：

Each man and each woman has the right to vote.

h.动词不定式、动名词或分句作主语时，谓语动词一般用单数形式。例如：

What I want to say is none of your business.

Listening to the classical music is enjoyable.

i.以-ics结尾的复数名词指一门学科时，如politics（政治学），mathematics

（数学），statistics（统计学），acoustics（声学），linguistics（语言学）等，谓语动词用单数形式。例如：

Mathematics is what he majors in.

2)下列结构作主语，谓语动词单复数形式取决于of 后的名词。

a.由“all,none,no,most,half,the last,the rest,the remainder+of +名词”等不定代词作主语，谓语动词单复数形式由of 后名词的单复数而定。例如：

None of the food is wasted.

None of the students were absent.

反意疑问句

反意疑问句主要由“陈述句+反意疑问”构成，反意疑问部分的动词一般要与陈述部分的动词相对应，反意疑问部分的主语要与陈述部分的主语相对应，如果陈述部分的主语是名词，则反意疑问部分用相应的代词表示。

1.反意疑问句的形式

反意疑问句一般有以下四种形式：

肯定陈述句+否定反意疑问句。例如：

This pencil is red,isn't it?

否定陈述句+肯定反意疑问句。例如：

This pencil isn't red,is it?

肯定陈述句+肯定反意疑问句。例如：

This pencil is red,isn't it?

否定陈述句+否定反意疑问句。例如：

This pencil isn't red,isn't it?

前两种形式是主要的，后两种不常见。

2.反意疑问句的用法

1）当陈述部分是there存在句时，反意疑问部分的主语用there。例如：

There aren't a lof of flowers in the garden in winter,are there?

There existed different oppinions on this issue,didn't there?

2）当陈述部分是以不定代词one作主语时，反意疑问句的主语在正式场合用one,在非正式场合用you。例如：One cannot succeed at this,can one?

One cannot succeed at this,can you?

3）当陈述部分是I'm...结构时，反意疑问部分一般用aren't I。例如：

I am a student,aren't I?

You told me (that)I had passed the exam,didn't you?

He says that everybody in our class will attend the meeting,dosen't he?

但是，当陈述部分的主句是I think,I suppose,I believe等结构时，反意疑问部分则往往由that从句中的主语和谓语动词决定，并且要注意否定的转移。例如：

I believe(that)it is going to rain,isn't it?

I don't think (that)be will come,will he?

5）当陈述部分的谓语动词是have时，反意疑问部分要根据have的意义及形式而定。

a.当have表示“所有”含义时，反意疑部厅以用have形式，也可以用do形式。例如：

He has a book in his hand,hasn't he?

He has a book in his hand,doesn't he?

b.当陈述部分的动词是have的否定形式时，反意疑问部分是用have形式还是用do形式，取决于陈述部分的动词形式。例如：

You haven't a car,have you?

You don't have any money with you,do you?

c.当have不表示“所有”含义而表示其他含义时，反意疑问句则必须用do的形式。例如：

We had a good time in the vacation,didn't we?

You have to get up early tomorrow,don't you?

6）当陈述部分带有never,nothing,nowthere,seldom,hardly,rarely,few,little

等否定词或半否定词时，反意疑问部分的动词用肯定形式。例如：

The wummit meeting never took place,did it?

You can hardly believe what he said,can you?

There is little ink in the bottle,is there?

Few people know this place,do they?

当陈述部分的谓语动词是带有un-，in-，dis-等否定前缀的动词，则仍然把陈述部分看作肯定句，那么反意疑问部分用否定形式。例如：

He is impolite to the teacher,isn't he?

He distrusted anybody around him,didn't he?

7）当陈述部分带有情态动词ought to时，反意疑问部分在英式英语中用ought to 形式，在美式英语中用should形式。例如：

You ought to see the new picture,shouldn't you?

Teachers ought to be honoured,oughtn't they?

8）当陈述部分带有情态动词used to时，反意疑问部分可以用used to形式，也可以用did形式。例如：

She used to live abroad,usedn't she?

There used to be a newsstand in the corner of the street,didn't there?

9）当陈述部分带有情态动词must时，反意疑问部分需视must的含义而定。

a.当must表示“命令或强制”时，反意疑问部分用mustn't。例如：

You must do it by yourself,mustn't you?

b.当must表示“有必要”时，反意疑问句用needn't，例如：

You must see him tonight,meedn't you?

c.当must表示“一定”或“想必”等推测意义时，反意疑问部分不用mustn't，而根据must后的动词形式而定。例如：

He must be crazy to do so,isn't he?

She must have been there for a long time,hasn't she?

They must have stayed at home last might,didn't they?

10）当陈述部分带有need时，反意疑问部分需视need的含义而定。如果need用作情态动词，则反意疑问部分用need形式；如果need用作实义动词，表示“需要”，则反意疑问部分用do形式。例如：

You needn't go there,need you?

She needs to fo there,doesn't she?

Plants need sun to grow,don't they?

11）当陈述部分带有I'd better或I'd rather时，反意疑问部分用hadn't或wouldn't。例如：

You'd better finish the task before tomorrow,hadn't you?

He'd rather stay with us,wouldn't he?

12）当陈述部分是祈使句时，反意疑问部分一般用will you，won't you,would you。例如：

Don't be too late,will you?

Close the door,won't you?

Come here,will you?

Open your books,would you?

当陈述部分是以Let's开头的祈使句时，反意疑问部分用shall we；若是以Let us 开头的祈使句，反意疑问部分则用will you。例如：

Let's have a party tonight,shall we?

Let us have a look at you pictures,will you?

注意，如果祈使句是否定形式，那么反意疑问句只能用will you。例如：

Don't forget to bring your notebooks here tomorrow,will you?

倒装句

倒装句主要出现在以下几种情况下：

1.当表语前置时，如果主语较长或主语结构比较复杂，需要倒装。例如：

Happy indeed are those who receive marvellous news after a long silence.

写作中真正实用的英语语法

第三节写作中真正实用的英语语法据考证，“语法”一词源于希腊语“Grammatike”，意指体现于写作过程中的“文字的技巧”，它是语言运用的规则，构建句子的框架，遣词造句的黏合剂，也是英语各项技能的基础，尤其在写作过程中起着举足轻重的作用。但四、六级考试改革中对语法题目的减少使很多人误以为语法的地位被削弱，加之近年来重视综合技能的各类语言理论的出现，使得一部分考生在写作复习过程中完全摈弃对语法部分的准备，久而久之，形成了“轻语法，重语感”的习惯。而另一部分考生则缺乏必要的语法运用能力，他们可以准确解答语法题目，却不能在作文中灵活运用语法写出漂亮句子。这些考生文章的共同特点就是只有其意，不见其形。语言是思维的外衣，准确的语法是高分作文的重要必备条件。如果考生能在写作中娴熟地运用语法技巧，就可以使文章逻辑严密，形神兼备。鉴于语法体系庞大繁杂而备考时间有限，此节内容无法涵盖整个语法体系，只能选择写作中出现频率较高的语法进行重点讲解，如状语前置、倒装、虚拟语气、强调句等，并辅以例句讲解，希望能够帮助考生扫除写作中的语法障碍，轻松闯关。状语前置一般而言，英语句子中，状语成分的位置是可前可后的。但状语的前置是六级作文中常用的句式。所谓状语前置，就是把修饰动词的状语结构，如分词短语，介词短语，动词不定式结构等放到句首。这一句式的最大优点就是断句自然，让单调的句子有跳跃的节奏感。请看下面句子： 1）With the expansion of industrialization, requirement for energy all over the world is on the rise.（随着工业化进程的发展，全世界的能源需求都在增加。） 2）Once lushly forested, this region has seen more than 80% of its original vegetation cut down or burned. (这个地区曾经丛林密布，但现在80% 的原生植被被砍伐或焚烧。) 3）To reach millions of people who watch television, advertisers are willing to pay big money. (为了能抓住千千万万的电视观众，广告商们不惜花费巨额资金。) 在以上例句中，状语的前置使得句子结构分明，避免了后置的平庸化，尤其是第二个句子中的状语部分，既简洁又有力，本身就是一个出彩的表达，如果放置到句尾就不会出现这种效果了。而第三句中不定式目的状语的前置还在一定程度上起到了强调的作用。倒装倒装又分为全部倒装和部分倒装。全部倒装是指将句子中的谓语动词全部置于主语之前。部分倒装是指将谓语的一部分如助动词或情态动词置于主语之前。如果句中的谓语没有助动词或情态动词，则需添加助动词do, does或did等,并将其置于主语之前。倒装的作用是为了强调或平衡句子结构。倒装本身是较复杂的高级结构，如果在六级写作中能加以正确运用，就特别

英语语法练习题(答案详细讲解)

英语语法练习题(答案详解) 1. Ms Nancy didn't mind at all ______ to the ceremony. A. being not invited B. not being invited C. not inviting D. not to be invited B 2."_____ your meeting is!" he offered them his sincere congratulations. A. How a great success B. What a great success C. How great success D. What great success B success 名词，保留远动词含义"成功"是不可数名词；如用来代替具体的人（成功者）或具体的事（成功的事情（东西））是可数名词。故排除C,D；A中how是副词，如改成how great a success就是正确的。 3. We must remember that _____fashion is not the most important thing in _______ life. A. /; the B. /; / C. the; / D. the; the B 抽象名词不特指时，前不用冠词。 4. It _____ quite a few years _____ the accused was declared innocent and set free. A. was; since B. is; that C. will be; when D. was; before D 如将A项中was, since改成is, since是正确的；即从句中谓语先发生。如用B项，是强调句，而强调句前后两个谓语动词在时间上必须一致（a）；被强调部分能还回原句中（b），即因为句中was declared是过去时, B项中is改成was；因为句中was declared是非延续性动词，在years后加上ago将"一段" 时间变成"一点"就是正确的。C 项前后时间不一致。

系统学习英语语法的好书

系统学习英语语法的好书怎样学习英语语法怎样学习语法呢？下面拟从四个方面简要谈一谈：（1）练好基本句型。我国近年来的英语教学实践证明：在初学阶段，采用听说、学习基本句型的方法去学习英语语法，是行之有效的。句型学习是通过听说的方法去学习传统语法里最常用的语法项目（把它们变为句型去操练）。句型训练实际上吸取了传统语法与结构语法两派的长处。当前国内的英语广播（电视）教学，在入门阶段，多采用句型教学法。所以自学者或者收听广播（收看电视）实行学习，或者根据所选用的课本提供的句型用替换词实行替换练习。所学的句型应该是由浅入深，由简到繁；讲求熟练掌握，不要贪多冒进。每学一个项目，首先要把单项练习练熟，然后过渡到综合练习，最后则应做到扩大使用。以定语从句这个项为例。把"I read a novel yesterday．和"It was extremely Interesting．"这两个单句改为"The novel I read yesterday was extremely interesting．"这就是定语从句的单项练习。首先要反复实行替换练习。如把"I saw a man this morning．"和"The man is my teacher．"改为"The man I saw this morning is my teacher．"把"I saw a film last night．"和"The film was very amusing．"改为"The film I saw last night was very amusing．"这种练习虽然是枯燥的，却是重要的基本功，务求把定语从句练到脱口而出的地步。这是第一步。第二步是把定语从句放在一定的语言情景中去综合使用，实行一问一答。如：A：Did you enjoy the opera？ A：The one we saw last night，of course． B：Yes，very much．第三步是扩大使用，也就是把定语从句和以前学过的两三个项目放在一起去操练。A：Do you know who Edgar Snow was？（一般问句；名词从句） B：Yes，he was an American writer who interviewed Chairman Mao in Beijing．（定语从句）
