初中英语语法——三大从句汇总(重点笔记)知识讲解

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?

I was crying while everyone was laughing. As I walked out, he walked in. as, when, while, 的区别 ① as强调从句的动作与主句动作同时发生及持续，具有at the same time的意思 他继续往下谈的时候，越来越兴奋。 as还可以表示一边??一边??，强调从句和主句中两个动作交替进行或同步进行。 他们边走边聊。 as还有“ 随着”的含义 随着春天的到来，天气暖和起来。 ② when 强调动作点的特定时间，具有at the time that 的意思 当老师走进来的时候，我们都站起来了。 ③ while 表示较长的期间，具有during the time that 的意思 当我在这的时候，我很安全。 2.主句发生在从句之前，这类从句由从属连词before, until 引导 ,before 意为“ 在---之前” until 在肯定句中意为“直到 --- 为止”，在否定句中意为“直到 --- 才”。从句既可置于主句前，也可置 于主句之后。 回家之前我必须干完所有的活。

高中英语的定语从句归纳与总结

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：

英语语法从句讲解

从句 从句按其在主句中的句法功能可分为三类: 即名词性从句、形容词性从句(即定语从句)和副词性从句(即状语从句)。 引导从句的词称作关联句. 一、名词性从句 引导这些名词性从句的关联词包括: 从属连词that, if, whether; 连接代词 who,whoever,whom,whomever,which,whichever,what,whatever,wh ose; 连接副词where, when, why, how。 其中, 从属连词只起连接作用, 在从句中不充当任何句法成分, 而连接代词和连接副词既起连接作用, 在从句中又充当一定的成分. That Owen should have married his cousin is not at all surprising. The fact is that he didn't go to the dinner party. I don't know if he will attend the meeting. Have you heard the news that Mary is going to marry Tom? 你听说玛丽要和汤姆结婚的消息了吗?(that引导同位语从句) [提示]

1. 在含有主语从句的复合句中, 为保持句子平衡, 常用it作形式主语,而将真正的主语从句置于句末. It's well-known that water is indispensable to life.(形式主语) 2. 为保持句子平衡, that引导的宾语从句也常用it代替, 而将真正的宾语从句置于主句句末。这常常出现在主句有形容词或分词作宾语补足语的情况下。 He made it quite clear that he preferred to live here. 3. 从属连词whether和if都作“是否…”解, 但if不可引导主语从句和表语 从句。whether可与or(not)连用, 而if不可以。 I don't know whether (if) she is at home. Whether she comes or not makes no difference. 4. that和what引导名词性从句的区别: that在从句中不充当成分,而what在从句中充当一定的成分, 如主语、表语、宾语等。that可省略, what则不可省。 He always means what he says. She suggested (that) he do it at once. 5. 同位语从句大多由从属连词that引导, 常跟在下列名词后面, 如fact, idea, opinion, news, hope, belief等, that不可省。同位语从句一般用来解释说明这些名词的具体含义和内容。 We are familiar with the idea that all matter consists of atoms. The news that we are invited to the conference is very encouraging.

初中英语状语从句知识点总结

初中英语状语从句知识点总结（一） 用来修饰主句中的动词，形容词或副词等而充当状语的从句叫做状语从句。状语从句常用从属连词来引导，与主句连接起来。若置于句末，则前面不加逗号。根据意义和作用，状语从句可分为时间原因条件等几种。下面我们就来分析一下这几种状语从句。 1时间状语从句 时间状语从句常用从属连词when,after,until,as soon as,等来引导。 当主句是祈使句或谓语动词是一般将来时态或情态动词时，其时间状语从句中的谓语动词常用一般现在时态表示将来发生的动作或存在的状态。这就是我们常说的“主将从现”。 如：Please call me when you get there.当你到那时，请给我打个电话。 I will write to you as soon as I arrive in Beijing.我一到北京就给你写信。 <温馨提示>since引导时间状语从句表示“自从…以来”，从句中的动词一般表示动作的起点，用过去时;而主句的动作延续的情况则用一般现在时或现在完成时。常用的句型为： It has been/is+一段时间+since+过去时。 如：I has been/is three years since we met last time.自从我们上次见面，已经三年了。 2条件状语从句 引导条件状语从句的连词或词组有：if(如果),unless(除非),as long as(只要)等。如果主句是将来时，条件状语从句也用一般现在时来表示。 如：I will stay at home if it rains tomorrow.如果明天下雨，我就待在家。 You can’t learn English well unless you wo rk hard. 除非你努力学习，否则是学不好英语的。 <温馨提示>由if引导的条件状语从句，若从句表达的是与现在事实相反的事实，则常用虚拟语气，即用过去时态表示(如果涉及到be动词，一律都用were)。此时，主句则用过去将来时。

初中英语语法——三大从句之表语从句

【初中英语语法——三大从句之表语从句】 【表语从句】 表语从句就是用一个句子作为表语。说明主语是什么或者怎么样，由名词、形容词或相当于名词或形容词的词或短语充当，和连系动词一起构成谓语。 表语从句只能置于主句之后，而主句的动词只能是联系动词。 名词性从句在be等系动词后作表语时被称为表语从句，例如： T he problem is how we can get the things we need.问题是我们怎样能弄到我们需要的东西。(how 在表语从句中充当方式状语)// The s cissors are not what I need. 这把剪刀不是我所需要的。(what 在表语从句中充当宾语)// What I told him was that I would find h im a good play. 我告诉他的是我会给他找个好剧本。(what在主语从句中作直接宾语， that作为表语从句的引导词在该表语从句中不充当句子成分，不能省略)// That is what I want to tell you.那就是我想要对你讲的。(what在表语从句中充当直接宾语)// That is why she failed to pass the exam. 那就是她考试不及格的原因。(why 在表语从句中充当原因状语) “That is why...”是常用句型，意为“这就是……的原因/因此……”，其中why引导的名词性从句在句中作表语，该句型通常用于针对前面已经说明过的原因进行总结，又如： That is why you se

e this old woman before you know, Jeanne. 珍妮，这就是现在这 个老太婆出现在你面前的原因。(前文提到Jeanne对老妇人显得苍老憔悴深感诧异，说话人对她讲述了其中的原因之后，用这一句来进行概括)。// That is why I came. 这就是我来的原因。 下面是两个与“That is why...”形式相似的结构，它们与“Tha t is why...”结构之间的关系要能够辨析清楚： (1)“That is why...”与“That is the reason why...”同义，只不过从语法结构上讲，“That is the reason why...”中why引 导的是—个定语从句，将其中的the reason去掉则与“That is why...”结构一样，例如： That is (the reason) why I cannot agree. 这就是我不能同意 的理由。 (2)“That is because...”句型中从属连词because引导的名词 性从句在此作表语，这也是个常用句型，意为“这就是为什么……/ 因为……”。“That is because...”与“That is why...”之间的不同在于“That is because...”指原因或理由，“That is why...” 则指由于各种原因所造成的后果，例如： He did not see the film last night. That is because he ha d to help his littl e sister with her homework.昨天晚上他没有

初中英语状语从句知识点总结

初中英语状语从句知识点总结(一） 用来修饰主句中的动词，形容词或副词等而充当状语的从句叫做状语从句。状语从句常用从属连词来引导,与主句连接起来。若置于句末,则前面不加逗号。根据意义和作用，状语从句可分为时间原因条件等几种。下面我们就来分析一下这几种状语从句。 1时间状语从句 时间状语从句常用从属连词wheｎ,aｆtｅｒ，unｔil,as soon as，等来引导。 当主句是祈使句或谓语动词是一般将来时态或情态动词时,其时间状语从句中的谓语动词常用一般现在时态表示将来发生的动作或存在的状态。这就是我们常说的“主将从现”。 如:Ｐlease cａll me ｗheｎ yｏu ｇeｔｔｈere．当你到那时,请给我打个电话。 I ｗill write tｏ you ａs ｓｏｏn as I arrｉｖe in Beｉjing.我一到北京就给你写信。 <温馨提示>siｎce引导时间状语从句表示“自从…以来”，从句中的动词一般表示动作的起点，用过去时;而主句的动作延续的情况则用一般现在时或现在完成时。常用的句型为： It hａs beｅn/is+一段时间+ｓｉnｃe+过去时。 如：I hａs ｂeｅｎ/is three yeａrs since ｗe meｔ laｓt ｔｉｍe.自从我们上次见面,已经三年了。 2条件状语从句 引导条件状语从句的连词或词组有：if(如果),unless(除非),as ｌｏnｇ as(只要）等。如果主句是将来时，条件状语从句也用一般现在时来表示。 如：I will ｓtａy at home ｉf it raiｎs tomorrｏｗ.如果明天下雨,我就待在家。 You can’t learn Englisｈweｌl unｌess you woｒk ｈard． 除非你努力学习，否则是学不好英语的。 <温馨提示>由ｉf引导的条件状语从句，若从句表达的是与现在事实相反的事实,则常用虚拟语气,即用过去时态表示(如果涉及到ｂe动词，一律都用wｅre)。此时,主句则用过去将来时。

初中英语语法-英语从句总结

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：
