Ⅳ 英语语法讲解复合句

复合句指的是含有两个或更多的主谓结构的句子，其中有一个（或更多）主谓结构充当句子的某一（些）成分，如主语、宾语、表语、定语、状语、同位语等。主语从句、宾语从句、表语从句、同位语从句、定语从句和状语从句都属于复合句。
一、状语从句：

状语从句 Adverbial Clause，从句用作状语称为状语从句。根据用途，状语从句可分为时间、地点、原因、条件、方式、让步、结果、目的等状语从句。

I. 时间状语从句
时间状语从句表示时间，常用的关联词有when, until, as, after, before, once, since, as long as, whenever等等。
例: 1) When you cross a main road, you must be careful.
2) He went out to play football after he had finished his homework.
3) Wait until you are called.

2) As I didn't know the way, I asked a policeman.
3) Since you won't help me, I'll ask someone else.
I'll take my raincoat in case it rains. (in case it rains = because it may rain)我将带上雨衣，以防下雨。

IV. 条件状语从句
条件状语从句表示真实的或现实的条件，引导从句所用的关联词有if, unless, suppose, in case(that), in the event (that), as (so) long as等等。
1) If it snows tomorrow, we will build a snowman.
You'll be late, unless you hurry.
3) Suppose we are late, what will he say? (suppose从句必须放在主句之前) 我们如果迟到了，他会说什么？
4) In the event that our team wins, there will be a party.
5) In case it rains, do not expect me. 如果下雨，就不要等我了。
6) He will do anything as(so) long as it is interesting. 只要好玩，他什么都愿意做。

V. 方式状语从句
方式状语从句表示动作的方式，回答How的问题，常用关联词as, as if, as though, the way(that), in the way(that)等引导，一般置于主语之后。
Do as I say. I did just as you told me. 照我说的去做。我就是照你说的去做的。

VI. 让步状语从句
让步状语从句表示“虽然、尽管、即使”等概念，使句子具有对比的因素。常用的关联词有although, though, even if, even though, not that(=although…not)等，置于主语之前或后。
1) Although you feel very ill right now, this is still a common disease.

VIII. 目的状语从句
目的状语从句表示目的，回答what for或 for what purpose的问题，常用关联词so that, in order that等引导，一般置于主语之后。目的状语从句中的谓语动词常由“情态动词+动词原形”构成。
Ships carry lifeboats so that people can escape if the ship sinks.
They wrote the notice in several languages so that foreigners could understand it.
We carved their names on the stone in order that people should always remember them.
They risk their lives so that/in order that they may support their kids.
二、定语从句

定语从句（Attributive Clauses）在句中做定语，修饰一个名词或代词，被修饰的名词,词组或代词即先行词。定语从句通常出现在先行词之后，由关系词（关系代词或关系副词）引出。

关系代词有：who, whom, whose, that, which等。
关系副词有：when, where, why等

1. 关系代词引导的定语从句

关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。

1）who, whom, that 这些词代替的先行词是人的名词或代词，在从句中所起作用如下：
Is he the man who/that wants to see you?
他就是你想见的人吗？（who/that在从句中作主语）
He is the man whom/ that I saw yesterday.
他就是我昨天见的那个人。（whom/that在从句中作宾语）

2) Whose 用来指人或物，(只用作定语, 若指物，它还可以同of which互换），例如：
They rushed over to help the man whose car had broken down.
那人车坏了，大家都跑过去帮忙。
Please pass me the book whose (of which) cover is green.
请递给我那本绿皮的书。

3） which, that 它们所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等，例如： A prosperity which / that had never been seen before appears in the countryside.
农村出现了前所未有的繁荣。（which / that在句中作宾语）
The package (which / that) you are carrying is about to come unwrapped.
你拿的包快散了。(which / that在句中作宾语)

2. 关系副词引导的定语从句

关系副词可代替的先行词是时间、地点或理由的名词，在从句中作状语。
1）when, where, why 关系副词when, where, why的含义相当于"介词+ which"结构，因此常常和"介词+ which"结构交替使用.例如：
There are occasions when (on which) one must yield. 任何人都有不得不屈服的时候。 Beijing is the place where (in which) I was born. 北京是我的出生地。
Is this the reason why (for which) he refused our offer?
这就是他拒绝我们帮助他的理由吗？

2）that代替关系副词that可以用于表示时间、地点、方式、理由的名词后取代when, where, why和"介词+ which"引导的定语从句，在口语中that常被省略.例如：
His father died the year (that / when / in which) he was born.
他父亲在他出生那年逝世了。
He is unlikely to find the place (that / where / in which) he lived forty years ago.
他不大可能找到他四十年前居住过的地方

3. 判断关系代词与关系副词
方法一： 用关系代词，还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语，就必须要求用关系代词；而不及物动词则要求用关系副词。例如：
This is the mountain village where I stayed last year.
I'll never forget the days when I worked together with you.

习惯上总把表地点或时间的名词与关系副词 where, when联系在一起。

方法二： 准确判断先行词在定语从句中的成分(主、谓、宾、定、状)，也能正确选择出关系代词/关系副词。
4. 限制性和非限制性定语从句
1) 定语从句有限制性和非限制性两种。限制性定语从句是先行词不可缺少的部分，去掉它主句意思往往不明确；非限制性定语从句是先行词的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开，例如：
This is the house which we bought last month.
这是我们上个月买的那幢房子。（限制性）
The house, which we bought last month, is very nice.
这幢房子很漂亮，是我们上个月买的。（非限制性）

2) 当先行词是专有名词或物主代词和指示代词所修饰时，其后的定语从句通常是非限制性的，例如： Charles Smith, who was my former teacher, retired last year.
查理·史密斯去年退休了，他曾经是我的老师。
My house, which I bought last year, has got a lovely garden.
我去年买的的那幢房子带着个漂亮的花园。
This novel, which I have read three times, is very touching.
这本小说很动人，我已经读了三遍。

3) 非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数，例如：
He seems not to have grasped what I meant, which greatly upsets me.
他似乎没抓住我的意思，这使我心烦。
Liquid water changes to vapor, which is called evaporation.
液态水变为蒸汽，这就叫做蒸发。

说明：关系代词that和关系副词why不能引导非限制性定语从句。

5. 介词+关系词
1）介词后面的关系词不能省略。
2）that前不能有介词。
3） 某些在从句中充当时间，地点或原因状语的"介词+关系词"结构可以同关系副词when 和where 互换。
This is the house in which I lived two years ago.
This is the house where I lived two years ago.
Do you remember the day on which you joined our club?
Do you remember the day when you joined our club?

6. as, which 非限定性定语从句
由as, which 引导的非限定性定语从句，as和which可代整个主句，相当于and this或and that。As一般放在句首，which在句中。
as 和which在引导非限制性定语从句时，这两个关系代词都指主句所表达的整个意思，且在定语从句中都可以作主语和宾语。但不同之处主要有两点：
(1） as 引导的定语从句可置于句首，而which不可。
(2） as 代表前面的整个主句并在从句中作主语时，从句中的谓语必须是系动词；若为行为动词，则从句中的关系代词只能用which。
7. 先行词和关系词二合一
1)Whoever spits in public will be punished here. (Whoever 可以用 anyone who 代替)
2)The parents will use what they have to send their son to technical school. (what 可以用all that代替)

8. what/whatever;that/what; who/whoever
1）what = the thing which；whatever = anything
2) who= the person that whoever= anyone who
3) that 和 what
当that引导定语从句时 ，通常用作关系代词，而引导名词性从句时，是个不充当任何成分的连接词。宾语从句和表语从句中的that常可省略。What只能引导名词性从句， 用作连接代词，作从句的具体成分，且不能省略。
9. 关系代词that 的用法
1）不用that的情况
a) 在引导非限定性定语从句时。
b) 介词后不能用。
2) 只能用that作为定语从句的关系代词的情况
a) 在there be 句型中，只用that，不用which。
b) 在不定代词，如：anything, nothing, the one, all, much, few, any, little等作先行词时，只用that，不用which。
c) 先行词有the only, the very修饰时，只用that。
d) 先行词为序数词、数词、形容词最高级时，只用that。
e) 先行词既有人，又有物时,只用that。
三、名词性从句：

在句子中充当主语、宾语、表语与同位语的句子分别叫做主语从句、宾语从句、表语从句和同位语从句， 这些统称为名词性从句。

（一）主语从句
在复合句中用作主语的从句叫主语从句。
A 为了强调主语从句的内容，可将从句置于句首
B 大部分主语从句都可以用it作形式主语

为了保持句子平衡，主语从句常用it作形式主语，将主语从句后置。用it作形式主语的主语从句结构有如下几种：
1、It is + 名词 + that从句
2、It is + 形容词 + that从句
3、It + 动词 + that从句
4、It is + 过去分词 + that从句
用形式主语it引导的主语从句相当多，有些已形成固定的语法和译法。常见的有：
It is said that... 据说……
It is reported that... 据报导……
It is well known that... 众所周知……
It is announced that... 据宣布……
It is believed that... 人们相信……
It is thought that... 人们认为……
It is understood that... 自不待言……
It must be pointed out that... 必须指出……
It must be admitted that... 必须承认……
（二）宾语从句

宾语从句 The Object Clause，在复合句中作主句的宾语，它属于名词性从句。它可以作主句谓语动词的宾语，也可以作介词的宾语。宾语从句以从句的句式来决定连接词。

宾语从句有四步曲
连接词： （也叫引导词）
语序： 从句的词序用陈述语序（主+ 谓）
时态： 主句的时态如果是过去时，从句的时态应以过去时为基础作相应的变化。
人称： 要根据句中的意义作相应的变化

连接词（引导词）
从属连词 that ，if ，whether
连接代词 who， whom， whose， which， what
连接副词 when ，where ，how ，why
1.如果陈述句作从句，连接词用that,在口语和非正式语体中常可省略that 。
2.特殊疑问句作从句，就用原来的特殊疑问词
3.一般疑问句作从句，连词用if或whether 在选择疑问句只用whether，记住这一结构：whether … or not 。
（三）表语从句

表语从句放在连系动词之后，充当复合句中的表语。

A 可接表语从句的连系动词
可接表语从句的连系动词有be, look, seem, sound, appear等。
B as, as if / though引导的表语从句
C because, why引导的表语从句
what引导的主语从句表示结果或名词reason作主语时，后面的表语从句表示原因时要用that引导，不宜用because。
D 使用虚拟语气的表语从句
在表示建议、劝告、命令含义的名词后的表语从句，谓语动词需用"should+动词原形"表示，should可省略。常见的词有：advice, suggestion, order, proposal, plan, idea等。
（四）同位语从句

同位语从句用于对前面的名词作进一步解释，说明名词的具体内容。同位语从句一般由that引导，但也可以由whether以及连接代词和连接副词引导。

A 同位语从句一般跟在名词的后面
同位语从句一般跟在名词fact, hope, idea, news, doubt, suggestion, information, opinion, decision, discovery, truth, promise, statement, problem, rule等后面。
B 使用虚拟语气的同位语从句
在一些表示“建议、命令、要求”的名词后的同位语从句中，谓语动词用"should + 动词原形"，should可省略。

Ⅵ 如何有效解决英语中名词复数的语法点

1、基本变化规则
①一般在名词后加s,变成复数.如boy→boys,pen→pens等.
②以s,x,sh,ch结尾的,在后面加es.如class→classes,fox→foxes,brush→brushes,watch→watches.但stomach的复数为stomachs.
③“以辅音字母+y”结尾的,y变为i,然后再加es.如baby→babies.
④以f或fe结尾的名词英语中共有100多个,其中直接加s的有92个,但这些绝大多数不常用,如safe,roof,belief等；把f或fe改为v,再加es的只有13个,但13个都是常用的名词,如thief,life,wife,shelf,self,knife,half,leaf,wolf等.
⑤以o结尾的名词,除有生命的“两人两物”Negro,hero,tomato,potato等少数在后面加es外,一般是在后面直接加s.如kilo→kilos,photo→photos,zoo→zoos,radio→radios,piano→pianos,video→videos.
2、不规则变化
①含man的名词,一般变man为men.如woman→women,policeman→policemen,Englishman→Englishmen.但German→Germans.
②将oo改为ee的有foot→feet,tooth→teeth,goose→geese等.
③复数以en结尾的有child→children,ox→oxen等.
④将ouse改为ice的有mouse→mice,louse→lice(虱子)等.

Ⅶ 英语复合句语法

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，通常可以独立存在；从句则是一个句子成分，不能独立存在。
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）引导。
复合句（The Complex Sentence）：句子中有一个或一个以上的从句，叫做复合句。复合句可分为：
1).定语从句（The Attributive Clause）；
2).状语从句（The Adverbial Clause）；
3).名词性从句（The Noun Clause）
一、 定语从句
· 定语从句的定义
定语从句在句子中作定语，用来修饰一个名词、名词词组或者代词。
· 先行词和引导词
被修饰的名词、名词词组或代词叫做先行词；
在先行词和定语从句之间起连接作用的词叫做引导词。
引导词分为“关系代词”和“关系副词”。
· 关系代词和关系副词
关系代词有：who, whom, whose, that, which, as。
关系副词有：when, where, why。 注意：关系副词里面没有how。
如果要修饰方式，用that或in which引导，或者不用引导词。
I don’t like the way (that, in which) he eyed me.
我不喜欢他看我的那个样子。
· 关系代词：who
关系动词who在从句中主要作主语，在非正式语体里who还可以作从句中的宾语。
He is the man who wants to see you.
He is the man who I saw in the park yesterday.
· 关系代词：whom
He is the man （whom） I saw in the park yesterday.
（whom在从句中作宾语）
· 关系代词：whose
whose 用来指人或物，（只能用作定语, 若指物，它还可以同of which互换）。
They rushed over to help the man whose car had broken down.
Please pass me the book whose cover is green. （of which the cover/the cover of which）
· 关系代词：which（1）
which指物，在从句中作主语或宾语，作宾语时在非正式语体中可以省略。
They needed a plant which didn't need as much water as rice.
The farm (which) we visited yesterday is located in the suburb of Beijing.
· 关系代词：which（2）
当在which和that面前进行选择的情况下，一般情况下要选which：
1.在非限制性定语从句中通常用which作引导词，而不能用that做非限制性定语从句的引导词。
2. 修饰整个主句。
I never met Julia again after that, which was a pity.
3. 修饰谓语部分。
He can swim in the river, which I cannot.
4. 介词 + which
They are all questions to which there are no answers.
· 关系代词：that（1）
that多用来指物，有时也可以用来指人；在从句中作主语或宾语。指物的时候多用that，也可用which。
It’s a question that (which) needs careful consideration.
（指物，作主语。）
Who is the man that is reading a magazine under the tree?
（指人，作主语。）
The girl (that) we saw yesterday is Tom’s sister.
（指人，作宾语，可省略。）
· 关系代词：that（2）
在以下的情况中，只能用that作引导词，而不能用which作引导词。
1. 先行词为all , everything, anything, nothing, little等不定代词时。
All (that) she lacked was training.
2. 先行词被形容词最高级修饰时
This is the best film that I have ever seen.
3. 先行词被序数词和the last修饰时
4. 先行词中既有人又有物时
They talked about the teachers and the schools that they had visited.
5. 主句是含有who或which的特殊疑问句，为了避免重复时
二、 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.
Wherever I am I will be thinking of you.
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。
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, in case等词引导，例如：
You must speak louder so that /in order that you can be heard by all.
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之间的转换既为 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.
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.
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, it is true.
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：

三、 名词性从句
1）.宾语从句（The Object Clause）；

在句子中起宾语作用的从句叫做宾语从句。宾语从句的引导词和主语从句的引导词相同。宾语从句可以作及物动词的宾语，作短语动词的宾语，介词的宾语。

whether, what, how可以用来引导同位语从句；而它们不能用来引导定语从句。

Ⅷ 英语语法

关于小学英语语法总结，我可以根据我孩子学习的小学英语语法总结给你简单交流一下。语法是英语中语言的结构规律。包括词法和句法。和中文的语句语法是一样的。也要掌握主谓宾语，孩子学习一定要知道单词的词义。我孩子学习语法是在能动英语学校学会的，他们主要是给孩子的学习中找方法。他们主要是用表音密码方法学习。首先要增加英语的词汇量，单词掌握的多了，就容易听懂。你可以先学习如何快速记单词。表音密码主要是破解百万英语单词的发音规律，只要记住发音规律 就可以达到见到单词就能读，读出来就能拼写的目的 。后期语法学习起来是非常轻松的。
