⑴ 求英语的全部语法
英语的时态(tense)是一种动词形式,不同的时态用以表示不同的时间与方式。
是表示行为、动作和状态在各种时间条件下的动词形式。因此,当我们说时态结构的时候,指的是相应时态下的动词形式。
英语时态分为16种:一般现在、一般过去、一般将来、过去将来时,以及这四者的进行时、完成时和完成进行时

D. Two years has passed since he joined the League.
十二、 一般现在时与现在进行时的转换
在一般现在时中,at加上名词表示“处于某种状态”,如at work(在工作), at school(上学、上课)等。此短语可与进行时态转换。请看:

C is being looked for D has been looked
解析:该题正确答案为C。在带有介词的动词短语用于被动语态句中,介词不能省,否则就变成了不及物动词短语,而不能用于被动语态的句子中。
短语动词
I. 要点
英语中有许多短语动词在意义上是一个整体,其用法有的相当于及物动词,有的相当于不及物动词,有的兼有及物动词和不及物动词的特征。英语短语动词的构成主要有以下六种:
(1) 动词+介词
常见的有look for, look after, send for, care about, ask for, laugh at, hear of (from), add to, lead to等。这类短语动词的宾语只能放在介词后。如:
Don't laugh at others.
I didn't care about it.
(2) 动词+副词
常见的有give up, pick up, think over, find out, hand in, point out等。这类短语动词的宾语如果是名词,既可放在副词前边,又可放在副词后边;宾语如果是人称代词或反身代词,则要放在副词前边。如:You'll hand in your homework tomorrow.
Please don't forget to hand it in.
(3) 动词+副词+介词
常见的有look down upon, go on with, break away from, add up to, catch up with等。这类短语动词的宾语只能放在介词后边。如:
All his money added up to no more than $100.
After a short rest, he went on with his research work.
(4) 动词+名词+介词
常见的有take care of, make use of, pay attention to, make fun of 等。这类短语动词的宾语只能放在介词后边。如:You should pay attention to your handwriting.
We should make full use of our time.
(5) 动词+形容词
常见的有leave open, set free, cut open等。这类短语动词的宾语如果是名词,则宾语可放在形容词的前边,也可放在后边;宾语如果是人称代词或反身代词,则必须放在形容词前边。如:
The prisoners were set free.
He cut it open.
(6) 动词+名词
常见的有take place, make friends等。这类短语动词用作不及物动词。如:
This story took place three years ago.
I make friends with a lot of people.
(7)辨析
give away(让给,暴露) 和 give up(放弃,停止)
put away(放起,收起) 和 put out (扑灭)
turn up(出席,放大) 和 turn on (打开)
keep out(阻止) 和 keep off (不让靠近)
make up(编造,补上) 和 make out(辨认)
take off(脱,起飞) 和 take out(拿出)
II. 例题
例1 It is wise to have some money ____ for old age.
A put away B kept up C given away D laid up
解析:该题正确uot;;give away意为"分发";lay up"贮藏"。例2 Here's my card. Let's keep in ____.
A touch B relation C connection D friendship
解析:该题正确答案为A. keep in touch为短语动词,意为"保持联系"。
例3 ____! There's a train coming.
A Look out B Look around C Look forward D Look on
解析:该题选A. look out 意为"小心"。
动词不定式
I. 要点
1、 不定式的形式。以动词write为例。
式|语态 主动语态 被动语态
一般式 to write to be written
完成式 to have written to have been written
进行式 to be writing
完成进行式 to have been writing
2、 不定式的句法功能
(1) 作主语
To hear from you is nice.
To be a good teacher is not easy.
不定式作主语时,为了保持句子的平衡,往往以it作形式主语,而不定式置于谓语动词后。如:It's nice to hear from you.
It's not easy to be a good teacher.
(2) 作宾语
通常用于want, hope, wish, like, need, hate, begin, start, remember, agree, learn, pretend, refuse, manage, help等词后。如:
I forgot to lock the door.
Please remember to write to me.
(3) 作表语
My job is to pick up letters.
He seemed to have heard nothing.
(4) 作定语
不定式作定语时,须放在它所修饰的名词或代词后。如:
I have two letters to write.
I have a lot of work to do.
(5) 作宾补
通常用于want, wish, ask, order, tell, know, help, advise, allow, cause, force等词后。如:
He ordered her to leave at once.
He was forced to obey his order.
(6) 作状语
He got up early to catch the first bus.
He worked hard to catch up with the other students.
(7) 作独立成分
To tell you the truth, I told a lie.
(8) "疑问词+不定式"结构。 如:
I don't know how to choose them.
I cannot decide where to go.
(9)不定式的否定式。如:
I decided not to go.
(10)不定式的完成式。如:
He seemed to have cleaned the room before I came in.
The boy is said to have been sent to the hospital last week.
(11)too…to 结构。如:
He was too excited to go to sleep.
He was only too glad to go. (他太高兴了,乐意去)
(12)主动表被动。如:
The book is easy to read.
I have a book to read.
II.例题
例1 I haven't got a chair ____.
A to sit B for to sit on C to sit on D for sitting
解析:该题选C。不定式to sit on在句中作定语,修饰名词chair. 因为不定式和它所修饰的名词间是"动宾关系",所以不定式必须是及物动词,故此处on不能省略。
例2 He was made ____. A go B gone C going D to go
解析:该题选D。make sb. do sth. 如果是被动形式,不定式do前的to不能省略。
例3 A new factory is ____ very soon.
A to be built B built
C to build D to building
解析:该题选A。is to be built意为"将要被建"。

(2)常与现在完成时连用的时间状语有:since, for, ring, over等引导出的短语;副词already, yet, just, ever, now, before, often, lately, recently等;状语词组this week (morning, month, year), so far, up to now, many times, up to the present等。例如:
1)I haven’t been there for five years.
2)So far, she hasn’t enjoyed the summer vacation.
3)There have been a lot of changes since 1978.
(3)完成时态可用在下列结构中:
This (That, It) is (was) the first (second…) time +定语从句;This (That, It) is (was) the only (last) + n +定语从句;This (That, It) is (was) +形容词最高级+ n +定语从句。如果主句的谓语动词是一般现在时,从句的谓语动词通常用现在完成时;如果主句谓语动词是一般过去时,从句谓语动词通常用过去完成时。例如:
(1)This is one of the rarest questions that have ever been raised at such a meeting.
(2)There was a knock at the door. It was the second time someone had interrupted me that evening.
2. 过去完成时
(1)表示过去某时间前已经发生的动作或情况,这个过去的时间可以用by,before等介词短语或一个时间状语从句来表示;或者表示一个动作在另一个过去动作之前已经完成。例如:
1)We had just had our breakfast when Tom came in.
2)By the end of last year they had turned out 5, 000 bicycles.
(2)动词expect, hope, mean, intend, plan, suppose, wish, want, desire等用过去完成时,表示过去的希望、预期、意图或愿望等没有实现。例如:
I had meant to take a good holiday this year, but I wasn’t able to get away.
另外两种表示“过去想做而未做的事”的表达方式是:
1)was / were + to have done sth, 例如:
We were to have come yesterday, but we couldn’t.
2)intended (expected, hope, meant, planned, supposed, wished, wanted, desired) + to have done sth, 例如:
I meant to have told you about it, but I forgot to do so.
(3)过去完成时常用于以下固定句型:
1)hardly, scarcely, barely + 过去完成时+ when + 过去时。例如:
Hardly had I got on the bus when it started to move.
2)no sooner +过去完成时+ than +过去时。例如:
No sooner had I gone out than he came to see me.
3)by (the end of ) +过去时间,主句中谓语动词用过去完成时。例如:
The experiment had been finished by 4 o’clock yesterday afternoon.
3. 将来完成时
将来完成时表示在将来某一时刻将完成或在另一个未来的动作发生之前已经完成的动作;也可以用来表示一种猜测。常与将来完成时连用的时间状语有:by (the time / the end of ) + 表示将来时间的短语和句子;before (the end of ) + 表示将来时间的词语或句子;when, after等加上表示将来动作的句子等。例如:
1)By this time tomorrow you will have arrived in Shanghai.
2)I shall have finished this composition before 9 o’clock.
3)When we get on the railway station, the train will probably have left.
4. 完成进行时
完成进行时是完成时的强调形式,有现在完成进行时,过去完成进行时,将来完成进行时。
(1)现在完成进行时表示过去某一时刻之前开始的动作或状态一直延续到过去某一时刻。例如:
I have been looking for my lost book for three days, but I still haven’t found it.
(2)过去完成进行时表示过去某一时刻之前开始的动作或状态一直延续到过去某一时刻。例如:
It had been raining cats and dogs for over a week and the downpour had caused landslides in many places.
(3)将来完成进行时表示在将来某一时刻之前开始的一个动作或状态一直延续到将来某一时刻。例如:
By the time you arrive tonight, she will have been typing for hours.
四:时态一致
时态一致是英语四、六级考试的一个重要内容。通常应由主句谓语的时态决定从句的谓语时态。一般原则是:
1、当主句谓语使用现在时或将来时,从句的谓语根据具体情况使用任何时态
He says that he lives in Wuhan.
We hope that there will be many people at your party today.
“Did you hear that Bill finally sold the house?” “Yes, but I don’t know who bought it.”
“There’s a lot of excitement on the street.”
“There certainly is. Do you suppose the astronauts have returned?”
2、当主句谓语使用过去时的时候,从句的谓语必须使用过去范围的时态
He said he was writing a novel.
The teacher wanted to know when we would finish the experiment.
He said his father had been an engineer.
3、当从句是表示没有时间概念的真理时,从句的谓语应使用一般现在时。例如:
The teacher told them since light travels faster than sound, lightning appears to go before thunder.
注:在此种情况下,即使主句谓语用了过去式的各种时态,从句谓语也应用一般现在时。
4、从句谓语只能用虚拟语气的情况
利用时态一致原则确定从句动词时态时,还应注意,若主语动词是表示命令、请求、要求、建议、劝告等的动词,从句谓语只能用虚拟语气,不能遵循时态一致原则。例如:
We insisted that we do it ourselves.
动词的语态
语态也是动词的一种形式,英语有两种语态:主动语态和被动语态。主动语态表示主语是动作的执行者,而被动语态表示主语是动作的承受者。
1)We use electricity to run machines. (主动语态)
2)Electricity is used to run machines. (被动语态)
1. 不能用于被动语态的动词和短语
(1)在英语中,不及物动词不能用于被动语态,但有些不及物动词(包括短语)容易引起误用。如:appear, belong, belong, die, escape, fall, happen, last, remain, succeed, occur, come true, take place, consist of。
(2)某些表示状态或特征的及物动词,如:become, contain, cost, fit, have, resemble, suit也没有被动语态。
2. 被动语态的时态形式
常用的被动语态有表1 所列的几种时态形式。
表1
时间 一般时 进行时 完成时
现在 am asked am being asked
is asked is being asked
are asked are being asked
过去
was be asked was being asked
were be asked were being asked
将来 shall be asked shall have been asked
will be asked will have been asked
过去 should be asked should have been asked
将来 would be asked would have been asked
3. 短语动词的被动语态
短语动词转换为被动语态时,通常被看作是一个动词,后面的介词或副词不能拆开或省略。例如:
1)So far no correct conclusion has arrived at.
2)All the rubbish should be got rid of.
4.“get + -ed分词”的被动语态
“get + -ed分词”结构强调动作的结果,而非动作本身,常用来表示突发性的,出乎意料的偶然事件。例如:
The boy got hurt on his way home from work.
另外,“get + -ed分词”还可用于谈论为自己做的事,是主动的行为而不是被动的行为。例如:
get dressed(穿衣服) get divorced(离婚)
get engaged(订婚) get confused(迷惑不解)
get lost(迷路) get washed(洗脸)
get married(结婚)
5. 能带两个宾语和复合宾语的动词改为被动语态
(1) 能带两个宾语的动词改为被动语态时,一次只能由一个宾语作主语,另一个宾语被保留下来。例如:
1)We showed the visitors our new procts.(主动语态)
2)The visitors were shown our new procts.(被动语态)
3)Our new procts were shown to the visitors.(被动语态)
(2)能带复合宾语的动词改为被动语态时,原来的宾语补足语变为主语补足语。例如:
1)The teacher appointed him League secretary.(主动语态)
2)He was appointed League secretary.(被动语态)
6. 被动语态与系表结构的区别
(1)The novel was well written.(系表结构)
(2)The novel was written by Diskens.(被动语态)
7. 少数动词的主动语态有时有被动的意思
例1:The book is selling remarkably well.
例2:The song sounds very beautiful.
能这样用的动词还有read(读起来),clean(擦起来),wash(洗起来),write(写起来)。
例3:My watch needs cleaning. (= My watch needs to be cleaned).
能像need这样用的动词还有:want, require, deserve, do, owe, bind等。
例4:The meat is cooking.
例 5:The book written by the professor is printing.
⑸ 英语语法总结,所有的
一、非谓语动词
“非谓语动词”可分为动词不定式、动名词和分词。它在句子中的作用很多:除了不作谓语外,它可以充当主语、宾语、表语、定语、状语与复合宾语(主语补语或宾语补语)。有些及物动词后面接不带to的不定式作复合宾语。这些动词归纳如下:一感(feel).二听(hear,listen to),三让(have,1et, make),四看(see,watCh,notice,observe)。再加上help somebody(to)do something和美国英语look at somebody do somthing。还有“二让”属特殊:get somebody to do something 与keep somebody doing。而有些及物动词后面接动名词(the -ing form)作宾语。这些动词归纳为一句话:Papa C makes friends。这是由如下动词的开头字母组成:permit,advise, practise,avoid,consider,mind, allow,keep,enjoy,suggest, finish,risk,imagine,escape,need,delay,stand(忍受)。 为了容易记住,也可以编成顺口溜:“允许完成练习,建议避免冒险,考虑延期逃跑,喜欢保持想象,需要反对忍受”。其相对应的动词依次是:permit/allow,finish,practise;
advise/suggest, avoid,risk: consider, delay, escape/miss; enjoy/appreciate, keep, imagine; need/want/require,mind. can't help/can’t stand。
二、复合句
1、学生最容易混淆的是定语从句与同位语从句的区别。
例如:A、The news that our team has won the match is true. (同位语从句)
B、The news that he told us surprised everybody here. (定语从句)
关键的区别在于连接或关系代词that:有意义的是定语, 无意义的是同位。因为引导定语从句的that在从句中作主语或 宾语,而引导同位语从句的that只起到连接词的作用。
2、接着容易混淆的是引导定语从句的关系代词that与 which:that之前是不定(代词)、序数(词)、(形容词)最高级:which之前是介词短语与逗号(非限制性)。
例如:A、All that we have to do is to practise every day.
B、The first lesson that I learned will never be forgotten.
C、I have lost my pen,which I like very much.
D、The house in front of which there is a garden is my home.
三、It的用法
1、It除了代替人和物以外,还可以作形式主语。而真正的主语(不定式、动名词或从句)则放于谓语或表语之后。
例如:It is nor easy to finish the work in two days.
然而有少数表语之后接动名词作真正的主语。这些表语是:无助(no help)、无用(no use)、没好处(no good);工作(hard work)、费时(a waste of time)、又危险(a danger)。
例如:A、It is no use crying over spilt milk.
B、It is a waste of time waiting for him.
2、It还可以作形式宾语。通常下列动词后面可接it作形式宾语:2f2tcjm(find,feel,think,take,consider,judge, make)。
例如:A、He made it clear that he was not interested in this subject.
B、I think it no use arguing with him.
3、It用于强调句式。要强调句子的某一部分(主语、宾语、 状语),可以把it当作先行词。这种句子的结构是:It is(was)+ 被强调部分+that(who)+句子的其余部分。
例如:A、It iS Professor Lin who teaches us English—(强调主语)
B、It was in Shanghai that l saw the film.—(强调状语)
C、It was in 1990 that I worked in the factory.(同上)
但要注意与定语从句的区别。
例如:D、It was 1990 when I worked in the factory.(定语从句)
在强调句式里,我们把强调结构It is(was)…that除去,句子还很完整。如例句C。而例句D就不能。
四、倒装结构
学生容易混淆的是全部倒装与部分倒装。如何区分之,编个顺口溜:副(adv.)介(prep.)提前全倒装,其它句式部分倒;否定提前倒助动,让步状语倒表语;复合句式倒主句,不
倒装的属特殊。下面举例说明:
A、Here comes the bus.(副词提前,全倒装)
B、Here he comes.(代词作主语,不倒装)
C、In front of the house lies a garden.(介词短语提前,全倒装)
D、Never shall I do this again.(否定词提前,部分倒装)
E、Young as he is ,he knows a lot.(让步状语从句,表语倒装)
F、Only when he told me did I realize what trouble he was in.(only 修饰状语,主句倒装)
G、Only he can save the patient.(only修饰主语.不倒装)
H、Not only will help be given to people,but also medical treatment will be provided.(否定词提前,部分倒装)
I、Not only he but also we like sports.(连接两个主语,不倒装)
五、虚拟语气
虚拟语气也是一个难点。所谓虚拟语气是表示说话人的愿望、假设、猜测或建议,而不表示客观存在的事实。它通过句子的谓语动词的特殊形式来表示。现归纳如下:纯假设,用虚拟,动词时态退一级:条件句,分主从,主句谓语前加would (should,could,might);表愿望,用虚拟,wish后面接宾语(从句):现在过去与将来,动词时态退一级:提建议,用虚拟,宾语(从句)动词用(should)do:俩建议,三要求,再加坚持与命令(suggest,advise,demand,require,request,insist,order):It is time和eoukd rather,后接丛句用虚拟:部分主语从句中, 谓语用虚拟结构 (It is necessry /important/natural/natural/strange/strange that……should do)。 下面举例说明:
A、If you came tomorrow,we would have the metting. (条件句虚拟)
B、Without air,there would be no living things.(同上)
C、We wish we had arrived there two hours earlier.(表示愿望虚拟)
D、He demanded that we (should)start right away.(表示建议虚拟)
E、It is(high)time that we left (should leave)now.(特殊从句虚拟)
F、I would rather you gave me the book.(同上)
G、It is necessary that we should clean the room everyday,(主语从句虚拟)
H、He speaks English so fluently as if he were English. (特殊从句虚拟)

⑺ 英语所有语法的主要规则
英语语法总结一.词性1. 实词1.名词 noun. N.名词是实词的一种,也是词性的一种,用来代替实体或抽象概念的词,可以独立成句。通常可以用代词来代替。A. 专有名词(Proper Nouns) -某个/某些人,地方,机构等专有的称呼,比如China, Mary.B. 普通名词 (Common Nouns)-一类人或东西,或一个抽象概念的名词,比如 book,friendship.2.代词(Pronoun) pron.代替名词的词类,大多数具有名词和形容词的功能。A.人称代词人称代词 第一人称单数 第二人称单数 第三人称单数 第一人称复数 第二人称复数 第三人称复数 主格 I you he/she/it we you they 宾格 me you him/her/it us you them 人称代词 第一人称单数 第二人称单数 第三人称单数 第一人称复数 第二人称复数 第三人称复数 形容词性物主代词 my your his/her/its our your their 名词性物主代词 mine yours his/hers/its ours yours theirs 汉语 我的 你的 他的/她的/它的 我们的 你们的 他(她、它)们的B.物主代词表示所有关系的代词叫做物主代词(Possessive Pronouns),也叫人称代词的所有格。物主代词分为形容词性物主代词和名词性物主代词两种。物主代词有人称和数的变化。第三人称单数的物主代词还有性别的变化(见上表)C.指示代词(demonstrative pronoun)表示指示概念的代词,用来指示或表示人或事物的代词。指示代词和定冠词以及人称代词一样,都具有指定的含义,用来起指示作用,或用来代替前面已经提到过的名词。指示代词的分类 (单数复数,既可作限定词又可作代词)单数 限定词:This girl is Mary.代词:This is Mary复数限定词:Those men are my teachers.代词:Those are my teachers.指示代词的句法功能指示代词在句子中可以充当:主语,宾语,表语,定语。 D.反身代词反身代词表示反射或强调的代词。它的基本含义是:通过反身代词指代主语,使施动者把动作在形式上反射到施动者自己。因此,反身代词与它所指代的名词或代词形成互指关系,在人称、性质、数上保持一致Myself, yourself, himself, herself, itself, ourselves, yourselves, themselves.E.关系代词用于引导定语从句,代表先行词,同时在从句中作一定的句子成分。有主格,宾格和属格之分,也分为指人和指物两种限定性 指人 非限定性 指物 限定性 指人或指物 主 格 who/that which/that that 宾 格 whom which/that that 属 格 whose of which/whose of which/whoseF.疑问代词1.疑问代词在句子中充当名词词组以构成疑问句What, who, whose, whom, which, whatever, whichever, whoever.2) 疑问代词在句中应位于谓语动词之前,没有性和数的变化,除who之外也没有格的变化。what, which, whose还可作限定词。G.相互代词相互代词(reciprocal pronoun)就是表示相互关系的代词。它与它所指代的名词或代词是一种互指关系,因此它们是复数或者二者以上。英语中的相互代词只有两个,即each other和one another传统语法认为,相互关系存在于两个人或物之间用each other, 存在于两个以上人和物之间用one anotherH.不定代词 不定代词,即不指明代替任何特定名词或形容词的代词 常用的不定代词:· some(something,somebody,someone),any(anything,anybody,anyone), no(nothing,nobody,no one), every(everything,everybody,everyone,),all,each,both,much,many,(a)little,(a)few,other(s),another,none,one,either, neither等 不定代词大都可以代替名词和形容词,在句中作主语、宾语、表语和定语I.连接代词疑问代词在引起从句时,都称为连接代词,包括who, whom, whose, what, which, whoever, whomever, whichever, whatever,一共九个,即除了whose后不能加“-ever”后缀,其余都行3. 数词 num.基数词 One, two, three… 一,二,三。。。序数词 First, second, third… 第一,第二, 第三。。。4. 形容词 adj.修饰名词或代词,表示事物的特征。5. 副词 adv.用于修饰动词,形容词,全句的词, 说明时间,地点,程度,方式等概念。可以分为时间副词,地点副词,方式副词,程度副词,疑问副词,连接副词,关系副词,频率副词,和说明性副词。6.动词 v.用来形容或表示各类动作的词汇,一个完整的句子中有至少一个动词2.虚词7. 冠词 art.冠词是虚词,不能单独使用。用在名词前面帮助指明名词的含义。冠词是名词的一种标志,它不能离开名词而独立存在,它表示主语的数量或特征。 8. 介词 prep.介词是一种用来表示词与词,句与句之间的关系的虚词,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,补语或者介词宾语。介词可以分为时间介词,地点介词,方式介词,原因介词和其他介词。 9. 连词 conj.连词是一种虚词,不能独立担任句子成分而只连接词与词,短语与短语以及句与句的作用。连词主要分为4类:并列连词,转折连词,选择连词和因果连词。 10.助词 助词是附着在词,短语,句子的前面或后面,表示结构关系或某些附加意义的虚词。助词有结构助词,时态助词,语气助词三种 11. 叹词 interj. 叹词是语法学术词。表示感叹,呼唤,应答的词。 3.判断词现代汉语中表示条件,让步,转折等关系的连词多包涵一个来自判断词“是”的语素,如 Yes 和 No. 4.情态动词1,,情态动词不能表示正在发生或者已经发生的事情,指标是期待或者估计某件事情的发生。2.情态动词除ought 和have 之外,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S4.情态动词没有非谓语形式,即没有不定时,分词等形式。 5.感叹词感叹词是用来表示说话时表达的喜怒哀乐等情感的词。它不构成后面句子的一个语法成分,却在意义上与它有关连,后面的句子一般说明这种情绪的性质、原因。感叹词是英语口语中最富于表现力的词语之一,用途甚广。学会它,对于提高英语的交际能力,表达复杂的思想起着举足轻重的作用。英语中的感叹词很多,但目前的语法著作中却很少对它进行归纳总结,致使许多人对含有感叹词的句子理解不透。现将部分感叹词的用法进行小结: 一、Oh 表示惊讶、指责、痛苦、称赞、懊恼等,可译为“哦”、“哎呀”、“噢”“啊”、“呀”等。 6.其他 1.动名词动名词是一种兼有动词和名词特征的非限定动词。它可以支配宾语,也能被副词修饰,动名词有时态和语态的变化。V-ing 2.动词不定式不定式:to+动词原形 不定式是一种非限定性动词(在句中不能单独充当谓语的动词,可分为不定式,动名词,现在分词和过去分词) 3.分词 具有动词及形容词二者特征的词。二.句子成分 (7种)主语,谓语,宾语,定语,补语,状语,表语1. 主语句子陈述的对象,说明是谁或什么。名词,代词,数词,动名词,不定式,一个句子,都可以作主语。2. 谓语对主语动作或状态的陈述或者说明,指出“做什么”和“是什么”或“怎么样”。谓语动词的位置一般在主语之后。3. 宾语指一个动作(动词)的接受者。宾语分为直接宾语和间接宾语(宾语补足语)两类。直接宾语指动作的直接对象,间接宾语说明动作的非直接,但是受动作影响的对象。一般而言,及物动词后面至少要有一个宾语(通常为直接宾语),有些及物动词要求两个宾语(通常一个为直接宾语,一个为间接宾语)。名词,代词,数词,动名词,不定式,一个句子,都可以作宾语。而to do 不定式用于宾语补足语。4. 定语用于修饰,限定,说明名词或代词的品质与特征。形容词,名词,代词,数词,介词短语,动词不定式,分词,定语从句或相当于形容词的词,短语,或句子都可以作定语。5. 状语修饰动词,形容词,副词等的句子成分。作用:说明地点,时间,原因,目的,结果,条件,方向,程度,方式和伴随状况等。一般用副词,介词短语,分词和分词短语,不定式或相当于副词的词或短语担当。一般位于句末,但也可以放在句首或句中。6. 补语作用于主语和宾语,起补充说明的作用。最常见的是宾语补足语。名词,动名词,形容词,副词,不定式,现在分词,过去分词都可以在句子中作宾语补足语。7. 表语表语用于说明主语的身份,性质,品行,特征和状态。常位于系动词(be, become, appear,seem,look,sound,feel,get,smell等词)之后。常由名词,形容词,副词,介词短语,不定式,动名词,从句充当。充当表语的句子叫做表语从句。三.基本句型结构 : 简单句,并列句和复合句 1. 简单句:5大基本句型 1.主语+谓语 主谓结构,谓语多为不及物动词 It happens. 它发生了。 2.主语+连系动词+表语 主系表结构 Leaves turn yellow. 叶子变黄了。 She is a teacher. 她是一名老师。 3.主语+谓语+宾语 主谓宾结构 谓语多为及物动词 I play the piano. 我弹钢琴。 4.主语+谓语+宾语+宾语主谓宾宾结构,谓语是可以有双宾语的及物动词。2个宾语一个是直接宾语,一个是间接宾语。 He gave the book to his sister. 他把这本书给了他的妹妹。 He gave his sister the book. 他把这本书给了他的妹妹。 5.主语+谓语+宾语+宾语补足语 主谓宾补结构,补语是宾语补语,和宾语一起构成复合宾语 I find the book easy. (easy作补语) 有时主语和谓语都不止一个但依然是简单句。 It 引导结构 It 既是代词又是引词 可以作为形式主语(It is +adj. +for/of sb. to do sth. )或形式宾语(it +adj. +to do sth. )It 也用于强调句结构。 It is (was) + 强调部分(主语,宾语或状语)+ that(who)… 2. 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。 基本结构:简单句+并列连词(and, but, so , or等)+简单句 3. 复合句 Complex Sentence 由一个主句和一个或一个以上的从句构成 主句通常可以独立存在而从句不能 从句必须由关联词引导
