高考语法了解一下英语的从句

⑴ 高中英语名词性从句和定语从句的语法总结（详细一点）

名词性从句是由if, whether, that 和各种疑问词充当连接词所引导的从句，其功同名词一样。

一．主语从句
主语从句是在复合句中充当主语的从句，通常放在主句谓语动词之前或由形式主语it代替，而本身放在句子末尾。
1. It 作形式主语和it引导强调句的比较
It 作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分，都可用连词that。被强调部分指人是也可用who/whom。
2. 用it 作形式主语的结构
(1) It is ＋名词＋从句
(2) it is ＋形容词＋从句
(3) it is ＋不及物动词＋从句
(4) it ＋过去分词＋从句
3. 主语从句不可位于句首的五种情况
(1) if 引导的主语从句不可居于复合句句首。
(2) It is said , (reported) …结构中的主语从句不可提前。
(3) It happens…, It occurs… 结构中的主语从句不可提前。
(4) It doesn’t matter how/whether …结构中的主语从句不可提前。
(5) 含主语从句的复合句是疑问句时，主语从句不可提前。
4. What 与that 在引导主语从句时的区别
What 引导主语从句时在句时在从句中充当句子成分，如主语．宾语．表语，而that 则不然。

定语从句也称为关系从句或形容词性从句，由关系代词（who, whom, whose, which, that）或关系副词（as, when, where, why）等引导。关系词除了起引导作用外，还在从句中指代前面的先行词，并在从句中担任一定的成分。
一、限定性定语从句和非限定性定语从句
定语从句就其与先行词的关系而言，可分为限定性定语从句和非限定性定语从句。限定性定语从句和先行词之间没有逗号，表示对先行词起修饰限制作用；而非限定性定语从句和先行词之间有逗号分开，是对先行词进行补充说明，相当于并列句。如：
He is the man who has strong personality. 他是个个性很强的人。（限定性定语从句）
My brother, who works abroad, is coming next week. 我哥哥在国外工作，他下周将回来。（非限定性定语从句）
注：1. 非限定性定语从句不能用that来引导，一般用which，as或who（指人）。用which或as引导时，既可以修饰主句的部分内容，也可修饰主句的全部内容。如：
He spoke confidently, which impressed me most. （which指代整个主句，在从句中作主语）
2. as引导的非限定性定语从句既可以放在主句之前，也可以放在主句之后，但which或who引导的非限定性定语从句不能放在主句之前。如：
As we all know, the moon is a satellite of the earth.
The large area is covered with thick snow, which affects people's life greatly.
3. 在限定性定语从句中，关系代词作宾语时可以省略；但在非限定性定语从句中，关系代词作宾语时不能省略。如：
The film (which) I saw last night is about a young teacher. (which可以省去)
She introced me to her husband, whom I hadn’t met before. (whom不能省去)

二、通常只用关系代词that，不用 which，who或whom的几种情况
1. 当先行词是all, everything, nothing, something, anything, little, much, none, few等时。如：
All that you want are here.
2. 当先行词被all, no, some, any, every, a few, a little, much, only, very等修饰时。如：
There is no person that doesn’t make mistakes.
3. 当先行词被序数词或形容词最高级修饰时。如：
This is the best film that I have ever seen.
4. 当出现两个或两个以上的先行词，并同时兼指人和物时。如：
We are talking about the people and countries that we have visited.
5. 当主句是以which 或 who 开头的特殊疑问句时。如：
Who is the person that is standing over there?
6. 当定语从句为there be 句型时，关系代词只能用that，但经常可以省略。如：
I know the difference (that) there is between you.
7. 当关系代词在从句中作表语时，常用that。如：
He does not seem to be the man that he was. 他似乎和过去不一样了。

三、as 与其他词连用引导的定语从句
as 引导定语从句时，可指人也可指物，通常与the same，such，so等连用，形式为：the same… as，such… as，as …as，so… as。As在定语从句中可作主语、宾语、表语等。如：
She knew he felt just the same as she did. 她知道他的感觉与她自己的一样。(as代替事，作宾语)
I lend you such books as will interest you. 我借给你使你感兴趣的书。(as代替物，作主语)
注：the same… as 和the same… that的用法不同。as引导的定语从句表示其内容与主句所讲的事物“相似”，指同类事物；that引导的定语从句表示其内容与主句所讲的事物是“同一个”，指同一事物。如：
This is the same pen as I lost yesterday. 这和我昨天丢的笔一样。（类似的笔）
This is the same pen that I lost yesterday. 这支笔就是我昨天丢的那支。（同一支笔）

四、“介词+关系代词”引导的定语从句
在“介词+which/whom”结构中，介词的选择取决于三种情况：
1．定语从句中谓语动词或表语的搭配。如：
This is the college in which I am studying.
He is the man about whom we are talking.
2．先行词与介词的习惯搭配。如：
The speed at which the machine operates is shown on the meter. 仪表上显示出这台机器运转的速度。
3．当定语从句为最高级时只能用of which; 否则用其他介词。如：
I have five dictionaries of which Longman Dictionary is the best.
I have five dictionaries among which Longman Dictionary is published in UK.
注：不可拆分的动词短语介词不能提前，如put up with；有的短语可能有不同的介词搭配，此时需要根据上下文来确定。如：be familiar with/to，compare with/to等。
有时为表意清楚，还可以在关系副词where/ when前加介词from, to等。如：
China is the birthplace of kites, from where kite flying spread to Japan, Korea, Thailand and India. 中国是风筝的故乡，从这里，放风筝的运动传到了日本、韩国、泰国和印度。

⑵ 高中英语语法几种从句的辨别方法及答题技巧

高中英语中共有三大从句：一、形容词性从句（即定语从句）；二、名词性从句；三、状语从句。

形容词性从句在句中起到修饰作用，相当于一个形容词，作先行词的定语，有限定性定语从句和非限定性定语从句之别。限定性定语从句不能随意去掉，否则句子意思无法表达明白。如：He is the man who bought my book yesterday. 如果去掉定语从句，此话没有什么意思。而非限定性定语从句与先行词关系不是很紧密，可以去掉，不影响主句的主要意思的表达。I met an old woman in the shop yesterday, who was about 80.

名词性从句共有四大类型：主语从句、表语从句、宾语从句和同位语从句。名词性从句，顾名思义，整个句子相当于句子中的一个名词，充当主句的主语、表语、宾语或者同位语。主语从句、表语从句、宾语从句只有在主句句子的成分残缺时才可以考虑使用以上三大从句。而同位语则是对前面某一名词的展开，即前一名词的具体说明，两者是同等，不是定语从句的修饰与被修饰关系。如：【同位语从句】We heard the news that he had gone to Beijing yesterday.此句中the news 和 that he had gone to Beijing yesterday.是同一意思，可以替换。the news 去掉，that 引导的则成了宾语从句，不过意思没变。

关于状语从句，主要是为主句谓语动词的发生提供一个时间（when)、地点（where）、条件（if）等等。常见的状语从句有：1.时间状语从句2.地点状语从句；3.原因状语从句；4.条件状语从句；5.目的状语从句；6.让步状语从句；7.比较状语从句；8.程度状语从句；9.方式状语从句；10.结果状语从句。

⑶ 高考用到的英语语法有哪些

高中阶段我觉得最主要学好如下知识点：
1, 定语从句
2，名词性从句（包括 主、宾、同、表内 四大从句)
3, 状语从句
4，非谓容语语
至于楼主提到的“定语从句”是什么意思？
我想：他应该就是，在句中做定语的从句就叫定语从句。在句中做什么成分就叫什么从句，记住就行！
何为 “定语”？如： cute cat 可爱的小猫 cute 形容词修饰名词，表示：“。。。的”这就是所谓的定语，假如这个“定语”是个带有主谓结构的句子我们就把它称为“定语从句”咯。简单吧呵呵。
至于用法，这里难一一诉说建议楼主，买本语法书来看看。
我强烈推荐： 高中英语各个击破（有详细解释），高考必备（字典）
望采纳谢谢

⑷ 高中要英语语法有几种各种从句的定义是怎样的怎样区分

高考中的从句分三来类：源名词性从句、定语从句以及状语从句，这些从句的区分是根据他们在句子中充当的成分，例如，在主从复合句中充当定语的从句就叫做定语从句。在主从复合句中充当状语的从句就叫做状语从句。
其中名词性从句分四种：主语从句、宾语从句、表语从句以及同位语从句。
定语从句分两种：限制性定语从句以及非限制性定语从句
状语从句分九种：时间状语从句、地点状语从句、原因状语从句、目的状语从句、结果状语从句、条件状语从句、让步状语从句、比较状语从句以及方式状语从句

⑸ 高考英语语法有几大考点啊

语法无非就考时态，语态，从句，非谓语动词。

一，时态方面，要区分什么时候用过去时，什么时候用完成时，还有过去完成时，这三个的用法往往都会混淆，所以经常考这个。辨别什么时候用这三个的哪一个，要看句子里面的时间标志词，画出句子中所有动作的时间轴，就很好做了。

二，语态方面，什么时候用被动语态，判断这个需要找动作发出者，而不是光看句子主语，要用自己逻辑判断，别被句子的主语迷惑。虚拟语态虽然有学，但不是重点考核对象，很少出。

三，从句。从句太多种多样了，高中的从句，定语从句是重点。一般考引导定语从句的关系代词或关系副词，还有定语里面的介词，是放在前面还是后面，这个也是常考的。

四，非谓语动词
1 现在分词的用法，做状语，做定语，要区分（注意，做主语那些动词ing叫动名词，不属于非谓语动词范畴）
2 过去分词用法，同上。
3 动词不定式，带to的和不带to的，动词不定式里加入时态和语态变化，也要注意，这是常考的点。

最后，关于做语法题，有几点很好用的提醒，以前我们老师常说。这里分享一下。
情态动词后面接动词“原形”
to不定式后面接动词“原形”
be动词后面接动词ing
很弱智吧，但是就算是高手，也会犯这些低级错误，往往就是顾着想其他方向而忽略这些最基本的东西。这也说明了一个问题，做语法题一定要注意各种细节。

以上。

⑹ 高中英语语法包括什么

一、关系代词引导的定语从句

1、that 指人或物在从句中作主语，宾语或表语

which 指物在从句中作主语，宾语或表语（作宾语时可以省略）

who 指人在从句中作主语，宾语或表语

whom 指人在从句中作宾语

whose 指人或物在从句中作定语

as 指人或物在从句中作主语，宾语或表语

but 指人或物在从句中作主语，宾语或表语

注意：指物时，whose+名词=the+名词+of which或 of which+the+名词

2、as 的用法

（1）常用于下列结构：such…as; so…as;the same…as; as…as

注意：the same…as 表示同一类，不同一个

the same…that 表示同一个

（2）as与which的区别

a、位置不同

as可放在主句后，主句前或主句中间；which只能放在主句后。

b、as起连接作用，表达说话人的观点、看法，并指出主句内容的根据或出处，意为“正如，正像”。

Which相当于并列句，可以用and this来代替，意为“这一点，这件事’”。

注意：as常用于下列结构：as we know/ as is known to all, as we all can see, as has been said before/above,

as might be excepted, as is often the case, 一般不能用which代替as。

c、在从句中作主语时，which既可作系动词be的主语也可作实义动词的主语，而as只可作系动词be的主语。

二、只用that不用which的情况

1、.先行词为 all , much, everything, nothing , something ,anything, nothing, none, the one等不定代词时

2、先行词被only, any, few, little, no , all, just , very ,right等修饰时.

3、 当先行词是最高级或被形容词最高级修饰时。

4、 当先行词是序数词或被序数词修饰时。

5、当先行词是数词时.

6、 当先行词既指人又指物时。

7、如有两个定语从句，其中一个关系代词已用which，另一个关系代词则宜用 that。

8、主句是There be结构,修饰其主语的定语从句宜用that 作关系代词。

9、被修饰成分为表语,或者关系代词本身是定语从句的表语时，该关系代词宜用that。

10、先行词为what，关系代词用that。

11、有时为了避免重复而使用that引导定语从句。

三、只用which不用that的情况

1、 当介词放在关系代词之前时。

2、 在非限制性定语从句中。

3、 当关系代词指整个主句的概念时。

四、只用who不用that的情况

1、当先行词是one, ones,anyone或those时。

2、there be 结构中。

3、当先行词是人，后面有较长修饰语时。

4、为了避免重复或引起歧义。

5、当先行词是I,you,he,they等时（常用于谚语中）。

6、先行词是指成员的集体名词。

7、who可以引导非限制性定语从句。

8、先行词是拟人化的名词。

9、先行词指特定的人时用who,不指特定的人用that。

五、关系副词引导的定语从句

1、when时间状语

注意：It/Ihis/That + be + the first/ second/ last time that… 只能用that,that可以省略，从句用相应的完成时。

2、where 地点状语

注意：当先行词为模糊的地点时，如point. Situation, case, position, stage, scene, spot, activity, family, job等名词时用where.

3、why 原因状语 先行词为reason。

六、介词与关系代词

1、介词如何确定

（1）依据定语从句中动词的习惯搭配来确定

（2）依据先行词的习惯搭配来确定

（3）根据意思来确定

（4）为了强调某一名词，不定式前加上关系词

2、关系代词作介词的宾语时，介词的位置

（1）whom和which可以和介词一起放在先行词和从句之间，也可以把介词放在从句中有关动词的后面。

（2）含有介词的短语动词一般不拆开，介词仍放在动词的后面。

（3）关系代词that在从句中作介词宾语时，介词不能放在它的前面，只能放在从句中有关动词的后面。

（4）关系代词whose也可以在从句中与它所修饰的名词一起作介词宾语。

3、“名词/数词/代词+介词+关系代词”结构常见的形式有：名词/one/two/some/none/all/both/several/many/most/a few/a little/the+比较级/the+最高级…+of+which/whom。

七、定语从句中的主谓一致

1、关系代词作从句的主语时，从句中谓语动词的人称和数要与先行词保持一致，先行词是句子时，从句的谓语动词用单数形式。

2、“one of+复数名词”位于关系代词前作先行词时，关系代词在从句中作主语，从句的动词通常用复数，但当one前有the,the only,the very等修饰时，从句的谓语动词要用单数。

八、注意way和time后接定语从句的情况

1、当先行词是way，且意为“方式、方法”时，引导定语从句的关系词有下列三种形式：that/in which/不填。

注意：关系词在从句中必须作状语。如果关系词在从句中作主语或宾语，按正常的定语从句分析。

2、当先行词是time时，若time作“次数”讲，应用that引导定语从句，that可省略；若time作“一段时间”讲，应用关系副词when或介词at/ring+which引导定语从句。

高中英语各种复合句精品课程讲解
（英语尖子生培训课
什么叫名词性从句？
在句子中起名词作用的句子叫名词从句 (Noun Clauses）
名词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、同位语等，因此根据它在句中不同的语法功能，名词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

【一】主语从句 【二】表语从句 【三】宾语从句
【四】定语从句 【五】同位语从句 【六】状语从句

【一】主语从句：在主句种充当主语成分的从句叫主语从句，
引导主语从句的连词有：从属连词；连接代词；连接副词
A 从属连词：that，whether。
从属连词；that，whether引导的主语从句在主语从句中不充当任何成分,只起连接词的作用，通常不可以省略。分句置于句首时，that绝对不可以省略。如果是由It作形式主语，后面that可以省略.
1,有that 引导的主语从句如下：
1. That the driver could not control his war was obvious.
=It was obvious（that）the driver could not control his car.
2. That she was chosen made us very happy.
=it made us very happy that she was chosen
3. That he is still alive is sheer luck. 他还活着全靠运气。
=It is sheer luck that she is still alive
4. That the whole project is doomed to failure is quite clear
=It is quite clear that the whole project is doomed to failure.
很清楚，整个计划注定要失败。
5. That you should have to leave is a pity
=It's a pity that you should have to leave.
你非走不可真是件憾事。
6. That he will refuse this piece of advice is impossible.
=It is impossible that he will refuse this piece of advice
7. That they should like each other is natural
=It is natural that they should like each other
8. That he will not come to the meeting this evening is true
=It is true that he will not come to the meeting this evening
9. That he will help others is a fact
10. That the earth turns around the sun is known to all.
=It is known to all that the earth turns around the sun.
11. That we can win is certain
=It is certain that we can win.
12. That you have made a mistake is a fact.
=It is a fact that you have made a mistake
13. It is ordered that we should leave at once.
14. That you don’t like him is none of my business.
用it作形式主语的that-从句有以下四种不同的搭配关系：
a. It + be +形容词+ that-从句
It is necessary that…有必要……
It is important that…重要的是……
It is obvious that… 很明显……
It’s certain that… 肯定…
It is possible that... 很可能……
It is unlikely that... 不可能……
It is necessary \important \natural\... that…

It occurred to me that…我突然想起……
It occurred to me that I forgot to send this letter
It happened that I came into the office at that time.
It is important(necessary / advisable / desirable / imperative / true / strange / possible ...)that ...需要注意的是,这类主语从句中,谓语动词很多为"(should)＋动词原形",即要用虚拟语气。例如:
It is necessary that several nurses (should) stay.
几个护士留在这儿是很有必要的。
It is imperative that everyone (should) learn from practice.
每个人都应该从实践中学习。
It is reported (well-known / hoped / thought / expected / said / believed / decided / suggested / ordered ...)that ...例如:

他是否会参加会议都无关紧要。
当用it作形式主语,而将主语从句放在句尾时,主语从句中的否定词常要前移至主句中。例如:
It doesn’t seem that they are from the same university.
It doesn’t appear that we’ll have a sunny day tomorrow.
if 不能用在主语从句中，而是用whether，如果主语从句放在句首，不能用if引导，但是如果用it 做形式主语，而把主语从句放在句末时，也可以用if引导.或把if 改为whether
If Mary really heard him is really doubtful.
正：It was doubtful if Mary really heard him.
正: Whether Mary really heard him is really doubtful.
Whether he left (or not) is unknown
Whether he will come is not clear.
Whether it will rain or not) is not clear

Whether the policeman will come is not certain.
Whether the 2000 Olympic Games will be held in Beijingis not known yet.
Whether we’ll go camping tomorrow depends on the weather.
whether he likes the job is not clear.
.注意区分it 作形式主语的主语从句与强调句
强调句句型It is/was+被强调部分+that, 去掉It is/was, that，句子仍然成立。
It is natural that they should have different views. 主语从句
It is only lately that he had had a family himself. 强调句
What was it that he wanted? I don’t know what it was that he wanted.
It was in the hotel where he stayed that we discussed the serious problem
8.注意it 作形式主语的主语从句和as引导非限制性定语从句引导的不同
It is known to all that the earth is round.
As is known to all. the earth is round.
B连接代词who ，what ，which, whatever, whichever, whoever (Who, whom, which, what可以和ever构成合成词，和what一样引导从句，ever起到强调作用。此类主语从句不能用形式主语it引导，它们在句子中担任成分，不能省略，语序为陈述语序)
What many scientists believe is that the earth is round …
Who will take part in the meeting has not been decided.
Whoever breaks the law will be punished.
Which student will win is uncertain.

Conclusion:主语从句作 主语时，谓语动词一般用单数形式
主语从句的规律
规律一、主语从句一律用陈述语序，即主语在前，谓语在后。
规律二、连词that 在从句中无实际意义，但不能省略。
规律三、whether 可以引导主语从句， 放在句首，但if不能
规律四、主语从句中的连词不能重叠使用
规律五、含主语从句的主句谓语动词多用单数第三人称形式。
规律六、what 引导的主语从句，可根据表语决定主句动词的单复数形式
规律七、主语从句为了避免头重脚轻现象，用 it 做形式主语，把从句放在后面。
