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.

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。

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。

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+which ”
的结构。

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whose” 引导的定语从句
“介词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。

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。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。

初中英语语法——三大从句汇总 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）。以 下是一些基本的从句的语法知识点 A、定语从句专项讲解与训练 一、定语从句概念 定语从句（attributive clause），顾名思义，就是一个句子作定语从属于主句。定语一般是由形容词充当，所以定语从句又称作形容词从句。另外，定语从句是由关系代词或关系副词引导的，故又称作关系从句。 定语从句一般放在它所修饰的名词或代词之后，这种名词或代词被称作先行词。请看示例： The woman who lives next door is a teacher. 先行词定语从句 在所有的从句中，算定语从句最难掌握，因为汉语里没有定语从句，汉语里只有定语，而且总是放在名词之前来修饰名词。 二、关系代词引导的定语从句 关系代词代替前面的先行词，并且在定语从句中充当句子成分，可以作主语、宾语、定语等。常见的关系代词有：who, that, which。它们的主格、宾格和所有格如下表所示： 先行词主格宾格所有格 人 who whom whose 物 which which whose of which 人、物 that that — （一）关系代词who, whom和 whose的用法 who代替人，是主格，在定语从句中作主语。例如： An architect is a person who designs buildings. 建筑师是设计房屋的人。
I will never forget the teacher who taught us chemistry in the first year of my senior middle school.我将永远不会忘记在高一时教我们化学的那位老师。 Anyone who wants to apply for this job must send us the resume by email first. 想应聘这个职位的任何人都必须先通过电子邮件向我们发送简历。whom代替人，是宾格，在定语从句作宾语，在非正式英语常可省略。例如：Do you know the gentleman whom we met in the school library yesterday? 昨天我们在学校图书馆里遇到的那位先生你认识吗？ This is the student whom my father taught ten years ago.这是我爸爸十年前教的学生。 The girl who I saw is called Mary. 我见到的那个女孩名叫玛丽。（在非正式英语中，主格who代替了宾格whom，亦可省略） whose一般代替人，有时亦可代替物，是所有格，在定语从句作定语。例如：The girl student whose father is a senior engineer used to study abroad. 其父是一位高级工程师的那个女学生过去在国外留学。 Do you know the name of the hotel whose window we can see here? 我们这儿能看到窗户的那个宾馆叫什么名字，你知道吗？（关系代词whose指代先行词hotel，正式用法应该用of which。whose window=the window of which，意思是：the window of the hotel。） （二）关系代词which的用法 which代替物，在定语从句作主语或宾语，作宾语时还可省略。例如： I do not like stories which have unhappy endings. 我不喜欢有不幸结局的小说。（which可以换成that） Tom works for a factory which makes watches. 汤姆在一个制表厂工作。（which可以换成that） （三）关系代词that的用法 that既可指人又可指物，在当代英语中大多指物，在定语从句作主语或宾语，作宾语时还可省略。例如： Is she the girl that sells newspapers? 她是卖报纸的那个女孩吗？（that可以换成who） Where is the ice-cream that was in the fridge?
一、句型1: Sｕbｊect (主语)＋Vｅrb (谓语） 这种句型中得动词大多就就是不及物动词,常见得动词如: ｗoｒｋ,sｉｎg, swim，f ｉsｈ, ｊump，arrｉve, e, die，ｄisappear，ｃry, happeｎ等。如: 1) Li Mｉng worｋｓvery haｒd、李明学习很努力。 2) Ｔhｅlittle gｉrl cｒied even ｈardｅr、小女孩哭得更厉害了。 3）The aｃｃident hａppeｎed yestｅrday aftｅrnoon、事故就就是昨天下午发生得。 二、句型2:Subｊeｃt (主语) + Link、Ｖ(系动词) +Pｒedｉｃate(表语） 这种句型主要用来表示主语得特点、身份等。其系动词一般可分为下列两类: (1)表示状态。这样得词有:ｂe,looｋ, sｅem,smelｌ,tasｔe, souｎｄ,ｋeep 等。如: １) Ｔhis kind oｆfoｏd ｔａsｔes deliｃiｏus、这种食物吃起来很可口。 ２) He ｌｏoｋed worｒｉeｄjust now、刚才她瞧上去有些焦急。 (2）表示变化。这类系动词有:bee，tuｒn，get, ｇrow, go等。如: 1）Sprｉｎg es、Itｉs gettｉng warmerａnd warｍｅr、春天到了,天气变得越来越暖与。 2) Tｈe treeｈaｓｇｒｏwn much taｌｌer than before、这棵树比以前长得高多了。 三、句型3：Suｂｊect(主语) + Vｅｒb (谓语)＋Oｂject （宾语) 这种句型中得动词一般为及物动词。其宾语通常由名词、代词、动词不定式、动名词或从句等来充当。 1）He tookｈis ｂag aｎd lefｔ、(名词）她拿着书包离开了。 2) LｉLｅi alwayｓhelps mｅwhen I havｅdifｆicｕlｔiｅｓ、(代词) 当我遇到困难时,李雷总能给我帮助。 ３)She plａns toｔraｖeｌｉn the ｉng Mａy Day、（不定式）她打算在即将到来得“五一”外出旅游。 4) Ｉdon’t know what Iｓhｏuｌd do next、(从句）我不知道下一步该干什么。
英步状从句用法（一） 步状从句的用法一（表示“ 然，即使，尽管”） 1. although ，though ，even though ，even if 都表示“ 然，即使，尽管”之意，though和although 气弱(其中的though 比although 通俗 , 不如 although正式)，even if和even though 有 意味而得气更。例如： Although they are poor, they are happy. 然他很，但很快。天气然很冷, 但他没有穿大衣就出去了。即使他可能不会成功，但他仍努力。那篇文 章然很短，但很重要。他好一点了，仍未痊愈。即使下雨，她也是走着去工作的。今晚我将去拜 他，即使我只能停留一小会儿。 注意： though引的步状从句的用法比特殊，它可以倒装，也可以不倒装，具体用 法参 as 引步状从句的用法。 2. as 引步状从句表示“ 然、即使、尽管”，其引的步状从句必采用倒装构， as 引的倒装形式的步状从句的基本构：形容/ 副 / 名 (数可数名前一般 不冠，有也可数可数名前形容与不定冠用、形容放在不定冠前)// 去分＋ as＋主＋的其他部分。注意体会下列典型例句：Great as the author was, he proved a bad model.位作者尽管了不起，到来却成了一个坏榜。真的。然他很富有，但他并不幸福。倒装要省去个名前的冠个故事看似荒唐，却是)尽管是个孩子，他却 能分辨黑白。他尽管勇敢，可到蛇是抖。尽管很重，他仍然十分。然尽了最大努力，但是他仍 然不能搬那石。 ［考1］ We had to wait half an hour ____ we had already booked a table.

高中英语从句大全 1）表语从句 1.定义：用作表语的从句叫做表语从句。 2.构成：关联词+简单句 3.引导表语从句的关联词的种类： （1）从属连词that.如： The trouble is that I have lost his address.麻烦是我把他的地址丢了。 （2）从属连词whether，as，as if.如： He looked just as he had looked ten years before.他看起来还与十年前一样。 The question is whether they will be able to help us.问题是他们是否能帮我们。 注：从属连词if一般不用来引导表语从句，但as if却可引导表语从句，如： All this was over twenty years ago，but it’s as if it was only yesterday. 这都是20多年前的事了，但宛如昨天一样。 能跟表语从句的谓语动词一般为系动词be，seem，look等。如： It looked as if it was going to rain.看起来天要下雨了。 （3）连接代词who，whom，whose，what，which，whoever，whatever，whichever 连接副词where，when，how，why. 如：The problem is who we can get to replace her.问题是我们能找到谁去替换她呢。 The question is how he did it.问题是他是如何做此事的。 That was what she did this morning on reaching the attic.那就是她今晨上了阁楼干的。 解释： 1.连词because可引导表语从句。如： I think it is because you are doing too much.我想这是因为你做得太多。 2.在一些表示“建议、劝说、命令”的名词后面的表语从句中，谓语动词用虚拟语气。should+动词原形表示，should可省略。如： My suggestion is that we （should）start early tomorrow.我的建议是我们明天一早就出发。2）主语从句 1.定义：用作主语的从句叫做主语从句。 2.构成：关联词+简单句 3.引导主语从句的关联词有三类： （1）从属连词that.如：That they were in truth sisters was clear from the facial resemblance between them. 很明显，她们确是亲姐妹，她们的脸型很相似。 （2）从属连词whether.如： Whether he’ll come here isn’t clear.他是否会来这里还不清楚。 （3）连接代词who，whom，whose，what，which，whoever，whatever，whichever 连接副词where，when，how，why.如： What she did is not yet known.她干了什么尚不清楚。 How this happened is not clear to anyone.这事怎样发生的，谁也不清楚。 Whoever comes is welcome.不论谁来都欢迎。 Wherever you are is my home —— my only home.你所在的任何地方就是我的家——我
定语从句 概念：定语从句，一个简单句跟在一个名词或代词后（先行词）进行修饰限定，就叫做定语从句。在主句中充当定语成分。被修饰的词叫先行词。定语从句不同于单词作定语的情况，它通常只能放在被修饰的词（即先行词）之后。定语从句由关系词（关系代词、关系副词）引导，关系代词、关系副词位于定语从句句首。 结构：先行词+关系词+从句 关系词： 关系词的类型：关系代词：who,whom,which,that,在从句中可作主语或宾语，whose,在从句中作定语 关系副词：why,where,when,其中why=for which，where=in/at/on which， when=during/on/in which,在从句中做状语 关系词的作用：1.连接作用，连接主句和定语从句 2.指代前面的先行词 3.在定语从句中担任成分 关系词的选择:1.看先行词（被定语从句修饰的词）先行词是“物”可能用which，that，whose,where，when，why等,先行词是“人”可能用who，whom，that， whose等 2.看关系词在定语从句中所担任的句子成分①先行词是人且关系词在从句 中作主语，用who/that②先行词是人且关系词在从句中作宾语，用 whom/that③先行词是物且关系词在定语从句中作主语，用that,which. ④先行词是物且关系词在从句中作宾语，用that,which，也可以省略 记住：关系代词作宾语或表语是可以省略的，作主语是不能省略的，因为主 语后直接是动词，省略的话就出现先行词直接接从句动词的语法错误。举例： Is there anything that you want to say? 中的that就可以省略。而He is the headmaster of this school who also teaches Chemistry. 中的who就不能省 略。⑤先行词是“人”或“物”，关系词在从句中作定语表所属关系，用 whose引导定语从句.注意：表示所属关系不仅仅是人,这个就叫做所属关系， 因此所属关系除了whose以外就有两个，对人是of whom,对物是of which. ⑥先行词是时间、地点或理由的名词，则用关系副词引导定语从句。注意： 如果从句中的谓语动词是及物动词且后面无宾语，那么，即使先行词是表时 间、地点或理由的名词，也不能用关系副词（when，why，where），而要用 可作宾语的关系代词that或which，要考试的同学们千万千万要记住哦！ 3.必须用that引导的情况①先行词是不定代词all, few, little, much, something, nothing, anything等②先行词被序数词或形容词最高级所修饰③先行词被 all, any, every, each, few, little, no, some等修饰④先行词被the only, the very, the same, the last修饰时⑤先行词既有人又有物时⑥当句中已有who时， 为避免重复用that 限定与非限定定语从句 定语从句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： 例：I like the book which he bought yesterday.(我喜欢他昨天买的书) 非限定性定语从句：
英语让步状语从句用法总结（一） 让步状语从句的用法一（表示“虽然，即使，尽管”） 1. although，though，even though，even if都表示“虽然，即使，尽管”之意，though 和although 语气较弱(其中的though 比although 通俗, 不如although 正式)，even if和even though 带有强调意味而显得语气更强。例如：Although they are poor, they are happy. 虽然他们很穷，但很快乐。天气虽然很冷, 但他没有穿大衣就出去了。即使他们可能不会成功，但他们仍努力尝试。那篇文章虽然很短，但很重要。他好一点了，虽仍未痊愈。即使下雨，她也是走着去工作的。今晚我将去拜访他，即使我只能停留一小会儿。 注意：though 引导的让步状语从句的用法比较特殊，它可以倒装，也可以不倒装，具体用法参见as引导让步状语从句的用法。 2. as引导让步状语从句表示“虽然、即使、尽管”，其引导的让步状语从句必须采用倒装结构，as引导的倒装形式的让步状语从句的基本结构为：形容词/副词/名词(单数可数名词前一般不带冠词，有时也可见单数可数名词前形容词与不定冠词连用、形容词放在不定冠词前)/动词/过去分词＋as＋主语＋谓语的其他部分。注意体会下列典型例句：Great as the author was, he proved a bad model. 这位作者尽管了不起，到头来却成了一个坏榜样。这个故事看似荒唐，却是真的。虽然他很富有，但他并不幸福。倒装时要省去单个名词前的冠词)尽管还是个孩子，他却能分辨黑白。他尽管勇敢，可见到蛇还是发抖。尽管伤势很重，他仍然十分乐观。虽然尽了最大努力，但是他仍然不能搬动那块石头。 ［考题1］We had to wait half an hour ____ we had already booked a table. A. since B. although C. until D. before ［答案］B ［解析］下划线处之后所述的“我们已经预订了一桌”与前面所述的“我们已经不得不等了半个小时”之间语意相反，四个选项中although表示“即便……”，引导让步状语从句最为合适。 ［考题2］____ most of the earth’s surface is covered by water, fresh water is very rare and precious. A. As B. Once C. If D. Although ［答案］D ［解析］句意为：虽然地球表面覆盖着水，但是纯净水仍然很稀有、珍贵。下划线处应引导让步状语从句，填入although最为合适。 ［考题3］____ he has limited technical knowledge, the old worker has a lot of experience. A. Since B.

A. his works are not widely read B. but his works are not widely read C. however his works are not widely read D. still his works are not widely read ［答案］A ［解析］英语不允许在连词although、though引导的让步状语从句之后的主句句首重复使用连词，如果要在复合句中强调某种特别的意义，可以在主句的句首加上yet、still等副词。例如：Although she has a lot of money, (yet/still) she is not happy. 虽然她很有钱，但是她并不快乐。
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）。 以下是一些基本的从句的语法知识点 A、定语从句专项讲解与训练 一、定语从句概念 定语从句（attributive clause），顾名思义，就是一个句子作定语从属于主句。定语一般是由形容词充当，所以定语从句又称作形容词从句。另外，定语从句是由关系代词或关系副词引导的，故又称作关系从句。 定语从句一般放在它所修饰的名词或代词之后，这种名词或代词被称作先行词。请看示例： The woman who lives next door is a teacher. 先行词定语从句 在所有的从句中，算定语从句最难掌握，因为汉语里没有定语从句，汉语里只有定语，而且总是放在名词之前来修饰名词。 二、关系代词引导的定语从句 关系代词代替前面的先行词，并且在定语从句中充当句子成分，可以作主语、宾语、定语等。常见的关系代词有：who, that, which。它们的主格、宾格和所有格如下表所示： 格 先行词主格宾格所有格 人 who whom whose 物 which which whose of which 人、物 that that —
（一）关系代词who, whom和 whose的用法 who代替人，是主格，在定语从句中作主语。例如： An architect is a person who designs buildings. 建筑师是设计房屋的人。 I will never forget the teacher who taught us chemistry in the first year of my senior middle school. 我将永远不会忘记在高一时教我们化学的那位老师。 Anyone who wants to apply for this job must send us the resume by email first. 想应聘这个职位的任何人都必须先通过电子邮件向我们发送简历。 whom代替人，是宾格，在定语从句作宾语，在非正式英语常可省略。例如： Do you know the gentleman whom we met in the school library yesterday? 昨天我们在学校图书馆里遇到的那位先生你认识吗？ This is the student whom my father taught ten years ago. 这是我爸爸十年前教的学生。The girl who I saw is called Mary. 我见到的那个女孩名叫玛丽。（在非正式英语中，主格who代替了宾格whom，亦可省略） whose一般代替人，有时亦可代替物，是所有格，在定语从句作定语。例如： The girl student whose father is a senior engineer used to study abroad. 其父是一位高级工程师的那个女学生过去在国外留学。 Do you know the name of the hotel whose window we can see here? 我们这儿能看到窗户的那个宾馆叫什么名字，你知道吗？（关系代词whose指代先行词hotel，正式用法应该用of which。whose window=the window of which，意思是：the window of the hotel。） （二）关系代词which的用法 which代替物，在定语从句作主语或宾语，作宾语时还可省略。例如： I do not like stories which have unhappy endings. 我不喜欢有不幸结局的小说。（which可以换成that） Tom works for a factory which makes watches. 汤姆在一个制表厂工作。（which可以换成that） （三）关系代词that的用法 that既可指人又可指物，在当代英语中大多指物，在定语从句作主语或宾语，作宾语时还可省略。例如： Is she the girl that sells newspapers? 她是卖报纸的那个女孩吗？（that可以换成who）

初中英语语法总结（从句） 英语从句三大类型 按一般说法，可分为三大类14种从句。 一,名词性从句 1主语从句Whether it's right or not remains to be seen. 2宾语从句I wonder whether it's right or not. 3同位语从句This is a question whether it's right or not. 4表语从句The question is whether it's right or not. 二,定语从句 1限定性定语从句She is the student who can speak English well. 2非限定性定语从句She is the student, who can speak English well. 三,状语从句 1时间状语从句The fact will come out when he comes here. 2地点状语从句You can go wherever you like.
3原因状语从句Pay more attention to your lessons because you are a student. 4方式状语从句He walks as if he were a king. 5目的状语从句She went to Japan so that she could learn Japanese well. 6结果状语从句She went to Japan so that she learned Japanese well. 7条件状语从句I will understand it if he tells me. 8让步状语从句He knows a lot though he is little. 1．定语从句 There are some old books in the box. The boy dressed in blue is from America. ?分清几个概念：先行词与关系代词/关系副词。先行词是指定语从句所修饰的中心词；关系代词主要有who, whom, whose, which, that; 关系副词主要有 when, where, why。关系代词和关系副词有两个作用，一是连接主句和从句的作用，二 是在定语从句中做成分。 ?定语从句分为：限定性定语从句和非限定性定语从句, 限定性定语从句如果去掉会影 响句子意义的完整性，非限定性定语从句即使去掉也不会影响句子意义的完整性，如： July is the month when we have a lot of rain. There are many plays (that) I’d like to see. The meeting was put off, which surprised us a lot. This note is left by Mary, who was here a moment ago. 1.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: 2. telephone，as we know，was the invention of Alexander Graham Bell． 3. D．Roosevelt，who died there on April 12，1945． 4. in a damp（潮湿的）house for a long time is harmful to one’s health，which is known to everyone． 5.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： 6.first doll that could say“mama”was invented in 1830． 7. second half of his voyage was by far the more dangerous part，during which he sailed round the Cape Horn合恩角． ?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：
