从句归纳-区分定语从句、宾语从句、同位语从句

各种从句总结：1.主语从句引导主语从句的连词有：that，where；疑问代词有：who，that，which；疑问副词有：when，where，why，how；（1）that引导的主语从句That在主语从句中无任何意义，不充当任何成分，通常不能省略。

例句：That he will succeed is certain.他会成功是肯定的。

常用it作形式主语，而将that从句置于句尾。

例句：It is certain that he will succeed.他会成功，这是肯定的。

若以that从句为主语的句子是疑问句，只能用it作形式主语。

例句：Is it certain that he will succeed?确定他会成功吗？It作形式主语位于句首时有以下四种结构：①It+be+形容词+that从句，例句：It is strange that no one wants to go there.真奇怪，竟然没有人想去那里。

②It+be+名词词组+that从句，例句：It is a pity that he can’t attend the party.真遗憾，他不能参加晚会。

③It+be+-ed分词+that从句，例句：It is said that he was a famous writer.据说他曾是一名著名的作家。

④It+seems/appears等不及物动词+that从句，例句：It seems that it is going to rain soon.看起来天马上要下雨了。

（2）whether引导的主语从句例句：Whether she will go there is not known.还不知道她是否要去那里。

（3）wh-疑问词引导的主语从句例句：What we need is your help.我们需要的正是你的帮助。

Why he did this is not known.他为什么要这样做还不知道。

三大从句语法讲解从句：在复合句具有主谓部分但不能独立成句的句子。

主句：除掉从句，就是主句在英语中，主要有三大从句：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）三大从句快速判断方法：1.主句不完整，从句不完整→名词性从句（连接代词）2.主句不完整，从句完整→名词性从句（连词、连接副词）3.主句完整，从句不完整→定语从句（关系代词）4.主句完整，从句完整→定语从句（关系副词）、同位语从句、状语从句名词性从句主语从句：（用句子代替名词来做主语）比如汉语中：①你通过我的方法学好了英语【主语】是我的荣幸。

②你要不要学英语【主语】是你自己的事。

③你想要的学习效果【主语】还必须靠你自己实现。

④你什么时候开始学英语【主语】是很重要的一件事。

基本：三类主语从句的连词（1）从属连词引导的主语从句（that / whether / if）that引导的主语从句:引导词that无含义/在句中不做成分/不可以省。

That 引导主语从句通常用it 作形式主语。

例如：That you will win the medal seems unlikely.（你要赢得这样比赛看起来不可能。

）That she survived the accident is a miracle.（她能在这场事故中幸存真是个奇迹。

）这个就同我们汉语例子中的①句一样，只不过英语中更加重视句子结构，所以把that放在前头，告诉你这个that后面跟的句子（和里面的主谓宾）不影响主句。

whether 引导的主语从句: whether有含义(是否)/在句中不做成分/不可以省。

注意：引导主语从句，不能用if不能在开头，只能用whether.Whether we will hold a party in the open air tomorrow depends on the weather.（我们明天会不会在户外举办聚会取决于天气。

英语中总共有六大从句,区分方法,用法,及例子如下：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,de cision.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.

英语中六大从句用法总结从句是指用于复合句中担当某个句子成分的主谓结构。

虽说从句自身的句子结构是完整的，但是它不能视为独立的句子，因为它离开了主语就无法独立、完整地表达意思。

按其所能表达的意义而言,它相当于一个词或是一个词组.按从句的句子功能划分（也就是按从句在句子中所担任的成分来划分），从句可分为：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。

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。

高中英语从句考点汇总,建议收藏！语法是很多同学薄弱的地方，想要努力提分，却总是感觉有些力不从心？这几天小编将高中英语关于从句的内容全部整理了一遍，这部分内容也是考试中经常出现有容易出错的部分，大家赶紧收藏起来仔细学习，把不懂的语法内容都捋顺！一、主语从句在主句中用作主语的主谓结构称之为主语从句。

例句：That he will come to the discussion is certain. 他来参加讨论是确定的。

That the moon moves round the earth iswell known to all of us.月球绕地球转动，这是我们大家都熟知的。

When the meeting is to be heldhas not yet been decide.会议什么时候召开还没有决定。

主语从句放在句首，句子常常显得比较笨重，因此通常可以把it放在句首，作形式主语，而将主语从句放在后面。

例如上面的句子可以分别改写为：It is certain that he will come tothe discussion.It is well known to all of us thatthe moon moves round the earth.二、宾语从句在主句中作谓语动词、介词及非谓语动词的宾语的主谓结构称之为宾语从句。

在引导宾语从句时，从属连词that在口语中和非正式文本中常省略。

He wants to tell us what he thinks.他想告诉我们他所想的事情。

Knowing that it was going to rain, they decided to work inside the house.知道要下雨了，于是他们决定在室内工作。
