1. 求英语从句语法资料！
在句子中起名词作用的句子叫名词从句(NounClauses） 名词从句的功能相当于名词词组,它在复合句版中能担任主语、宾权语、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。 给你分享一份“英语语法大全”:，更多资料到Vickey新概念英语上学习！
2. 英语语法英语从句
主要是宾语从句和状语从句，如果说考的稍微难一些的话就是定语从句以及名词性从句，一般考的话后两者的难度不会很大。
宾语从句在句中作及物动词或介词的宾语，从句放在主句之后，前后不用逗号分开。
宾语从句：
引导宾语从句的词有：
连词that(在口语中that常可省略)，if, whether,如：
He knows that Jim will work hard.
连接代词who, whom, which等，如：
Do you know who (whom) they are waiting for?
连接副词when, where, how, why等，如：Could you tell me how we can get to the station?
3.whether和if都有“是否”的意思，一般情况下两者可以换用，但在介词之后，
不定式之前，与or not连用，在句首或在引导表语从句，同位语从句时，只能用whether,如：I want to know if/whether the news is true. He doesn't know whether to stay or not?
4.宾语从句要用陈述句语序。
5.宾语从句一定要注意时态呼应，即：当主句谓语动词是过去式时，从句中谓语动
词也要用过去范畴的时态，但若从句陈述的是真理或客观规律，其谓语的时态仍用一般现在时，如：
He asked who could answer the question.
My father told me that the earth goes around the sun.
6.一个宾语从句只能用一个连词。
7.当主句谓语动词是think, believe等动词时，宾语从句的否定意义要放到主句中。另外，当主句主语为第一人称时，后面若接附加疑问句，那么附加疑问句的主语、谓语应与从句中的主谓语保持一致。如：
I don't think he looks like his father, does he?
8.直接引语和间接引语也是宾语从句，直接引语是引述别人的原话，放在引号内，
不用连词联接；间接引语是用自己的话转述别人的话，通常用连接词与主句联接。
(1)陈述句变为以that引导的宾语从句，如：
He said,“I'm happy.”[FY()[FY]]He said that he was happy.
(2)一般疑问句变为if(whether)引导的宾语从句，如：
He asked me,“Does his father know Mr Green?”
---He asked me if his father knew Mr Green.
(3)特殊疑问句变为由who, what, where, how等疑问词(连接代词或连接副词)引导的宾语从句，如：
He asked me,“Where is Mr Wang?”
---He asked me where Mr Wang was.
注意上述例句中连词、时态、语序等变化
3. 英语中从句的语法大全
英语中六大从句用法总结
1.主语从句
1）主语从句可直接位于主语的位置，如果从句较长，谓语又较短，可用it作形式主语，而将从句放在句末。常见的句型有：
*It is a fact\a pity\a question\good news that...
*It seems\appears\happened\has turned out that...
*It is clear\important\likely\possible that...
*It is said\reported\estimated\has been proved that...
It is said that comic books create a connection between people of the same generation.
It seems that the performance is very useful.
2)what引导的主语从句表示“...的东西时”，一般不用it作形式主语。
What we lack is experience.
3)what,who,when,why,whether等词含有各自的疑问意义，但它们引导的主语从句，都用陈述语序。
How the plan is to be carried out should be discussed again.
I did know why I felt like crying.
2.宾语从句
1）宾语从句可位于及物动词、介词和某些形容词后。连词that常可省略。介词后一般接疑问词引导的宾语从句。in that(因为),except that(除了),but that(只是）已构成固定搭配，其他介词后一般不接that引导的宾语从句。
*I promised that I would change the situation.
*All this is different from what American young people would say about friendship.
*He is certain that watching so much television is not good for children.
*This article is well-written except that it is a bit too long.
2)宾语从句后如有宾补，要用形式宾语it来代替，而把宾语从句移至宾补之后。
He has made it clear that he would not change his mind.
3)在think,believe,suppose,expect等动词后的宾语从句中，如果谓语是否定的，一般将否定词移至主句谓语上，宾语从句则变成肯定形式。
He didn't think that the money was well spent.
3.表语从句
表语从句出现在结构为“主语+系动词+表语从句”的句子中。表语从句除可用that,what,when,why,whether,how等引导外，还可由because,as if(though)等引导。that常可省略。如主句主语为reason,只能用that引导表语从句，不可用because.
Perhaps the most important thing to remember is that there is no one common type of life in America.
The reason why so many people died there is that there were not enough food supplies.
It looks as if successful international cultural communication will make the world smaller.
4.同位语从句
同位语从句用于对前面出现的名词作进一步说明，一般用连词that引导，由于先行名词的意义不同，也可用whether,who,when,where,what,why,how等引导。常见的先行名词有fact,idea,belief,news,hope,conclusion,evidence,suggestion,order,problem,report,decision.有时由于谓语较短，将同位语从句位于谓语之后。
She finally made the decision that she would join the fashion show.
I had no idea how many books I could borrow at a time.
The news came that their team had won the championship.
5.定语从句
定语从句所修饰的先行词可以是名词或代词，也可以是一个句子。定语从句通常位于先行词之后，由关系代词或关系副词引导。
*限制性定语从句
限制性定语从句修饰先行词，对先行词起修饰作用，紧接先行词之后，无逗号，若省去，原句意思不完整。引导定语从句的关系代词有who,whom,whose,which,that等。who,whom,whose用于指人，whose有时也可指物，相当于of which；which用于指物；that既可指人也可指物，但只用于限制性定语从句中。关系代词除了引导定语从句，替代先行词外，还在从句中担任主语、宾语、定语等。
The computers and cables which make up the Internet are owned by people and organizations.
Those who live alone or who are sick may have trouble in getting close to other people.
The girl whose parents died in an accident is living with her grandmother.
1)当先行词是all,anything,everything,something,nothing等不定代词或先行词前有first,last,any,few,much,some,no,only以及形容词最高级修饰时，只能用关系代词that引导从句。
That is all that I've heard from him.
He's the first person that I'm going to interview this afternoon.
2)关系代词的省略
在从句中作宾语的关系代词常可省略。关系代词紧跟介词，作介词宾语时不可用that，只可用which或whom引导从句，并且不可省略，但当介词位于宾语从句句末时，作为介词宾语的关系代词仍可用that，也可省略。
This is one of those things with which we have to put up.
This is one of those things (which\that) we have to put up with.
3)引导定语从句的关系副词有when,where,why等。关系副词在从句中作状语，意义上相当于一个“介词+which”的结构。
Even in comic books where(=in which) there are no words,the stories are fully expressed through the drawings.
No one knows the reason why(=for which) he was so angry that day.
5.定语从句
*非限制性定语从句
非限制性定语从句既可修饰先行词，也可修饰整个主句，起补充说明作用，与主句之间有逗号隔开，若省去，原句意思不受影响。不可用that引导非限制性定语从句。关系词不可省略。
Every object has a gravitational pull,which is rather like magnetism.
*“介词+which\whom\whose”引导的定语从句
“介词+which\whom\whose”可引导限制性定语从句，也可引导非限制性定语从句，该结构中介词的选择取决于从句谓语动词的固定搭配，或先行词的习惯搭配。
This is the computer on which he spent all his savings
It is written by a person with whom we are all familiar.
*as引导的定语从句
as引导的定语从句主要用于“such...as”及“the same...as”的结构中，代替先行词是人或物的名词。as引导非限制性定语从句时，代替整个主句，从句可位于主句之前、之后或中间。
These are not such problems as can be easily solved.(as代替先行词problems)
As is mentioned above,no single company or group can control what happens on the Internet.(as代替主语)
6.状语从句
*时间状语从句
引导时间状语从句的从属连词和词组有：
1）when,whenever,while,as,after,before,since,till,until,once等。
We have learnt quite a lot about it since we came here.
2)as soon as,hardly(scarcely)...when,no sooner...than,each(every) time,the moment,immediately(that)等。
As soon as I sent an e-mail message,I received positive responses.
The moment he heard the good news,he jumped with joy.
*地点状语从句
引导地点状语从句的连词是where,wherever.
Wherever she went,she took her little daughter with her.
*原因、结果和目的状语从句
1）引导原因状语从句的从属连词有：because,as,since,now(that),seeing that,considering that,in that等。
Considering that he is a freshman,we must say he is doing well.
2)引导结果状语从句的连词有：so...that,such...that
,so that,that,so等。
Mickey Mouse is so attractive that the children are reluctant to leave.
3)引导目的状语从句的连词有：so that,in order that,for fear that,lest等，从句常使用may,might,can,could,would等情态动词。
We got up early this morning so that we could catch the first bus to the railway station.
*条件和让步状语从句
1）引导条件状语从句的连词和词组有if,unless,as(so) long as,on condition that,in case,provided(providing) that,supposing等。
As long as you have the right equipment,you can use a telephone line to transmit computer data.
2)引导让步状语从句的连词和词组有though,although,whether,even though,even if,no matter what(when,how...),whatever(whenever,wherever,however....)等。though,even if等引导状语从句可转换成含有as的部分倒装结构，具有强调意义。其结构为“形容词（副词、动词、名词）+as+主语+谓语”。
No matter what you may say,I would not change my mind.
Young as he is,he is quite experienced in this work.(=though he is young)
Child as he is,he can speak English fluently.(=though he is a child)
*方式状语从句
引导方式状语从句的连词有as,just as,as if,as though等。as if,as though引导的状语从句中，谓语动词常用虚拟语气，表示与事实相反。
The young man made the experiment just as the teacher had taught him.
Everything went on as usual as if nothing had happened.
4. 英语语法及从句知识
其实这些从句仔细说起来有点复杂，不是一两句就能解释得清的！而且从初中到高中，再到大学，从句一直是个很麻烦的问题！！在这里一两句话是绝对解释不清的！
简单来讲，英语的句子结构跟中文相近，唯一不同的是中文里面的句子成分中没有补语！
英文里的一句话，一般的成分是：主谓宾定状补。这六个部分，而所谓的从句，简单来讲，就是靠一些能够引起从句的词，像what,where,that,whether,if,how……（这些词要下来多看书，多积累）来引导一个句子，而这个句子在这整句话中则会充当一定的成分，它当什么成分就是什么从句。
给你举个简单的例子吧：I
don't
know
whether
you
like
it
or
not.
在这句话中，I是主语，谓语是don't
know
，know是一个动词，后面必定会跟一个宾语，所以不管后面句子的引导词是什么，后面紧跟know的必定是一个宾语从句！！whether
you
like
it
or
not.这是一句话而不是一个单词吧，所以是从句！！
总之，只要摸清了句子成分，做从句其实很容易的，毕竟从句在初中和高中里的限定很多，不会太深奥。只要平时下了功夫的，应该没问题！建议你买本语法书，好好研读一下，毕竟从句时重点！！书上会很详细！
加油吧！
5. 初中英语从句语法讲解
你可以把书后的语法整理啊。
不就是宾语从句、状语从句和定语从句吗？
6. 英语语法中的从句
大致有下面几种（以下是我个人总结的，仅供参考）：
一、名词性从句
其中又包括主语从句、同位语从句、宾语从句、表语从句
What I have is only a piece of bread.(What引导的主语从句)
News spread in the village that he came back.(that引导的同位语从句)
I think that you are right.(that引导的宾语从句)
What I appreciate is that you are brave.(that引导的标语从句)
二、形容词性从句
也就是定语从句
The mountain is beautiful from the top of which we can see our school.(which 引导的定语从句)
三、状语从句
主要有时间状语从句、地点状语从句、原因状语从句、条件状语从句、目的状语从句、让步状语从句、比较状语从句、程度状语从句、方式状语从句、结果状语从句
I will call you as soon as I arrive in Beijing. （as soon as引导的时间状语从句）
You should have put the book where you found it.(where引导的地点状语从句)
I hate you because you hurt me.(because 引导的原因状语从句)
If it is convenient,I will help you.(if引导的条件状语从句)
You must speak louder so that you can be heard.（so that 引导的目的状语从句）
She passed the examination though she had not studied very hard.(though引导的让步状语从句)
She finds it easier to read than to write．（than引导的比较状语从句）
7. 英语，从句，语法
这句话里 in order 用的不对。抄 in order to 在一起用，加动词原形，表示 为了某个目的。
这句话可以说： Mom got up early in order to see me off at the airport.
如果用从句，那就用 ...so that...， 也是为了某个目的的意思。句子就写为：Mom got up early so that she could see me off at the airport. that...后面的从句表目的。用了could （过去时）是和主句时态一致。
表目的，是状语从句。
8. 谁能讲一下英语中从句和各种语法
这个很多的，不好说呀，不过推荐给你一本不错的书呦，书名是高中英语语法，黑皮的，里面讲得很详细，很易懂的，很不错，对你会有帮助的。
9. 高中的英语语法，从句部分的讲解
高三英语语法重点难点点拨 <<陈老师课堂>>
高中英语状语从句讲解
一．原因从句
1. 由as／because／since 引导的原因从句：
We camped there as／because／since it was too dark to go on．我们在那里露宿是因为天太黑，不能再继续往前走了。
As／Because／Since it was too dark to go on，we camped there．因为天太黑不能再继续往前走，我们就在那儿露宿了。
2. in view of the fact that可用as／since／seeing that来表示，但不能用because： As／Since／Seeing that you are here，you may as well give me a hand．既然你在这儿，就帮我个忙吧。
As／Since／Seeing that Tom knows French，he’d better do the talking．既然汤姆懂法语，最好让他来谈。
二．结果从句
结果状语从句——引导结果状语从句的连词有：so that, so…that, such that, such…that, that等。当从句前面有逗号时，so that中that可省略，如：
It was dark, so (that) we could see nothing in front of us.
“So + 形容词 / 副词 + that”是引导结果状语从句的常用结构，如：
He talked so loud that he annoyed the speaker. He was so brilliant that he made a lot of inventions.
“such (a) + 形容词 + 名词 + that”与“so…that”的意义相同，如：
It was such a hot day that people could not go out. He painted such beautiful pictures that the visitors were lost in admiration.
such／so…that引导的结果从句
A such是形容词，用于形容词+名词结构之前：
They had such a fierce dog that no one dared to go near their house．他们有一条如此凶猛的狗，以致没人敢靠近他们家。
He spoke for such a long time that people began to fall asleep．他说了这么长时间，以致在座的人都犯困了。
B so是副词，用于副词和不带名词的形容词之前：
The snow fell so fast that our footsteps were soon covered up．雪下得这么快，以致我们的脚印很快就被雪盖住了。
His speech went on for so long that people began to fall asleep．他的讲话这么长，以致在座的人都开始犯困了。
Their dog was so fierce that no one dared come near it．他们的狗太凶猛了，所以没人敢靠近它。
such不能用于much和many之前，so可用于后跟名词的much和many之前：
There was so much st that we couldn’t see what was happening．灰尘太大了，使得我们看不清发生了什么事。
So many people complained that they took the programme off．抱怨的人太多，所以他们取消了那个节目。
C 注意：such＋a＋形容词＋名词可由so＋形容词＋a＋名词来代替，所以such a good man可由so good a man来代替。这只能在名词前面有a／an的情况下使用。
热点之一：含有否定意义的副词放在句首引起的部分倒装
此类副词有：not，never，seldom，hardly，rarely，little等。例如：
Not a single word did he say at the meeting．（在会上，他什么也没说。）
热点之二：含有否定意义的连接词置于句首引起的部分倒装
此类连接词有：not only．．．but also，neither．．．nor．．．，no sooner．．．than，scarcely．．．when，hardly．．．when等。请看例句：
No sooner had she gone out than the telephone rang．（她一出门电话就响了。）
热点之三：搞清so（nor ，neither）＋助动词＋主语与so（nor ，neither）＋主语＋助动词之间的区别
前者表示重复前句部分的内容，译为“也是如此”。而后者表示对前句内容的进一步肯定或证实，译为“确实如此”。例如：
Lily can't answer the question．Neither can I．莉莉不能回答这问题。我也不能。
Tom was late for school yesterday．So he was. 汤姆昨天上学迟到。他确实如此。
热点之四：省略if的虚拟条件句以had ／were ／should开头引起的部分倒装
这是虚拟语气中比较特殊的一种，其实质就是省略if后引起的变化。如：
Had he worked harder，he would have got through the exams．（要是他努力学习的话，他是会通过考试的。）
热点之五：not until置于句首引起后面句子的部分倒装
not until意为“直到……才……”，位于句首时引起后面的主句倒装。如：
Not until the teacher came did he finish his homework．老师来了他才完成作业。
热点之六：only短语置于句首引起的部分倒装
only放在句首，修饰副词、介词短语或状语从句，常引起后面句子部分倒装。如：
Only in this way can you learn English well．只有通过这种方式，你才能把英语学好。
让步从句
它们由下列词来引导：although，though，even though，even if，no matter，however有时也可以使用whatever。as也可以，但是只限于形容词＋as＋be结构。
Although／Though／Even though／Even if you don’t like him you can still be polite．尽管／即使／纵然／即使你不喜欢他，你仍可有礼貌一些。
No matter what you do，don’t touch this switch．无论怎样，都别碰这个按钮。
However rich people are，they always seem anxious to make more money．无论人们多么富有，他们似乎总还渴望赚到更多的钱。
However carefully you drive，you will probably have an accident eventually．无论你开车多小心，最后你大概还会出车祸。
Whatever you do，don’t tell him that I told you this．无论如何，别跟他说这件事是我告诉你的。
Patient as he was，he had no intention of waiting for three hours．哪怕他再有耐心，也不打算等上三个小时。
比较从句
He didn’t play as well as we expected／as well as you（did）．他打得不如我们预料的好／你打得好。
He sings more loudly than anyone I’ve ever heard／than anyone else （does）．他唱得比我听到的任何人唱得都响／比任何人都声音响。
You work harder than he does／than him／than I did at your age．你比他干得卖劲／我在你这个年龄时干得卖劲。
时间从句
A 时间从句由下列表示时间的连词来引导：
after immediately till／until no sooner…than when as soon as since whenever before the sooner while hardly…when the minute the moment
B 时间从句中不用将来时态。
1 如将下列将来时态放入时间从句中，须将它变为一般时态。
You’ll be back soon．I’ll stay till then．= I’ll stay till you get back．你会很快回来，我一直等到那时。
C since从句
since从句后面常跟完成时态
They’ve moved house twice since they got married．／Since they got married，they’ve moved house twice．他们结婚后已搬了两次家。
He said he’d lived in a tent since his house burnt down．他说自从他的房屋被烧毁后，他就一直住在帐篷里。
It’s ages since I sailed／have sailed a boat．我未驾驶帆船已有好多年了。
I haven’t sailed a boat since I left college．自从我大学毕业后就没再驾驶帆船了。
D after从句
after从句之后常跟完成时态：
After／When he had rung off I remembered… 等他把电话挂断后，我才想起……
After／When you’ve finished with it，hang it up．你用完了之后，请把它挂起来。
E hardly／scarcely… when，no sooner… than
The performance had hardly begun when the lights went out．= Hardly had the performance begun when the lights went out．演出刚开始就停电了。
这里可以用scarcely代替hardly，但不常见。
He had no sooner drunk the coffee than he began to feel drowsy．= No sooner had he drunk the coffee than he began to feel drowsy．他喝咖啡没多一会儿，就犯困了。
He no sooner earns any money than he spends it．= Immediately he earns any money he spends it．他钱一挣到手，就花光了。
注意the sooner…the sooner的用法：
The sooner we start，the sooner we’ll be there．我们动身得越早，到那儿就越早。
10. 英语从句的知识请讲一下怎么用，有哪些常用的方式和语法规则
先你要弄清什么是定语`表语`同位语`主语`宾语`
没有谓语从句
从句是相对于主句而言的，即它是从属于某一个主句，而不能单独作一个句子。在英语中，主要有三大从句，即名词性从句（包括主语从句，宾语从句，表语从句，同位语从句）、形容词性从句（即定语从句）、副词性从句（即状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等）。
