英语语法名词性从句

英语语法Unit16名词性从句

名词性从句（Noun Clause）在句子中起名词作用，根据它们在句中所起的语法作用，这类从句又可分别称为主语从句、表语从句、宾语从句、同位语从句和形容词补语从句。由于名词从句和名词作用相同，因此，可用作句子的主语、表语、宾语和介词宾语等。

英语语法英语从句完全汇总

英语语法: 英语从句完全汇总一.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。例如： It is a pity that you didn’t go to see the film. It doesn’t interest me whether you succeed or not. It is in the morning that the murder took place. It is John that broke the window. 2. 用it 作形式主语的结构 (1) It is +名词+从句 It is a fact that …事实是… It is an honor that …非常荣幸 It is common knowledge that …是常识 (2) it is +形容词+从句 It is natural that…很自然… It is strange that…奇怪的是… (3) it is +不及物动词+从句 It seems that…似乎… It happened that…碰巧… (4) it +过去分词+从句 It is reported that…据报道… It has been proved that…已证实… 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。例如： It is said that President Jingo will visit our school next week. (right) That President Jiang will visit our school next week is said. (wrong) (3) It happens…, It occurs…结构中的主语从句不可提前。例如： It occurred to him that he failed in the examination. (right) That he failed in the examination occurred to him. (wrong) (4) It doesn’t matter how/whether …结构中的主语从句不可提前。例如： It doesn’t matter whether he is wrong or not. (right) Whether he is wrong or not doesn’t matter. (wrong) (5) 含主语从句的复合句是疑问句时，主语从句不可提前。例如： Is it likely that it will rain in the evening? (right) Is that will rain in the evening likely? (wrong) 4.

英语语法讲解之定语从句

英语语法讲解之定语从句时间：2016-08-12作者：来源：学习方法网一．几个基本概念 1.定语从句的定义：用作定语的从句叫定语从句。 2.先行词：被定语从句所修饰的名词或代词。 3.定语从句的位置：紧跟先行词(名词或代词)之后。 4.引导词：引导定语从句的词(包括关系代词和关系副词)。 ﹙1﹚关系代词：that/who/whom/which/as ﹙2﹚关系副词：when/where/why 5.引导词的位置：位于定语从句之前(先行词之后)。【as除外】 6.引导词的功能(作用)： ﹙1﹚连接先行词和定语从句。 ﹙2﹚在定语从句中充当一定的成分(关系代词充当主语或宾语，关系副词充当状语)。 7.定语从句的类型： ﹙1﹚限定性定语从句(主句和定语从句之间无逗号)。 ①直接由引导词引导定语从句 The man who you’re talking to is my friend. ②由介词+关系代词(whom/which)引导 The man to whom you’re talking is my friend. I need a pen with which I can write a letter.

=I need a piece of paper on which I can write a letter. 介词的选用可根据从句中的相关词组确定，该介词通常可以放在关系代词之前，也可放在从句之尾。例如： The man (who/whom/that) I talked about at the meeting is from Beijing University. =The man about whom I talked at the meeting is from Beijing University. The palace (which/that) I often pay a visit to was built in the 17th century. =The palace to which I often pay a visit was built in the 17th century. ﹙2﹚非限定性定语从句(主句和定语从句之间用逗号隔开)。 ①直接由引导词引导定语从句。 ②由介词+关系代词(whom/which)引导。 I live in a house far away from the city，in front of which is a big tree. There is an apple tree standing at the gate，on which are many apples. This is the man to whom I gave the book. ③由“代词/名词+of+whom/which”或“of which/ whom +名词/代词”(先行词指人用whom，指物用which)引导。One，some，any，none，all，both，several，many，most，neither，either等词、数词、分数或百分比与of whom或of which连用。 He has five children，two of whom are abroad. (比较：He has five children，and two of them are abroad.) We have three books，none of which is/are interesting. (比较：We have three books，but none of them is/are interesting.) 除why和that不能引导非限定性定语从句外，其余引导词都可以，用法同限定性定语从句一样。但要注意以下区别。

初中英语语法从句讲解

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。关系词常有3个作用：1，引导定语从句。2，代替先行词。3，在定语从句中担当一个成分。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 1）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。2）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） 3）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.

初中英语语法宾语从句讲解-专项练习及答案

初中英语语法宾语从句讲解小口诀：宾语从句三注意，时态语序引导词；主句一般现在时，从句不需受限制；主句一般过去时，从句须用相应时；陈述转化that引，一般疑问用if/whether, 特殊问句疑问词，引导词后陈述式。一．基本讲解来源：直接引语变间接引语概念:在句中担当宾语的从句叫宾语从句。 Eg: He said,“I am good at drawing”. He said he was good at drawing. (动词宾语) 1.引导词 (1) that引导宾语从句时，通常用陈述句充当, that可省略。 Eg: She said,“I want to go there ”She said (that) she wanted to go there. (2) whether 或if 引导的宾语从句,由一般疑问句/选择疑问句充当，陈述语序。 Eg: “Are you interested in geography?” she said. She asked if/whether I was interested in geography. I wonder if /whether she has told the new to Li Lei . I’m not sure whether he will come or not. 注意：一般情况下，whether 和if 可以互用，但有些情况例外 a. 介词短语后只用whether 不用if eg: We are talking about whether we'll go on the panic. b. 引导词与动词不定式或or not 连用时，只用whether. eg:I can?t say whether or not he will come on time c. if当如果讲时,引导的是条件状语从句，表示‘如果’，不能用whether. Eg: If you want to be a good teacher, it will take times. Whether you can succeed depends on how much effort you pay. (3).特殊疑问词引导宾语从句时，不可省略，陈述句语序。特殊疑问词为：how , when, where, why ,which whose. E.g. …What do you want?? He asked. He asked me what I wanted. I have no idea where he is now. I don?t know how to deal with it. He asked whose handwriting is the best in the class. 2.宾语从句时态 a.主句为一般现在时，从句不受主句的限制 eg: Do you know if/whether he has seen the film? I?m sorry to hear that your father is ill. She says she is going to go to Beijing next week. He tells me that his sister came back yesterday. b.当主句是一般过去时，从句用过去的相应某种时态 She didn?t know why the boy was late again. (过去一般) I didn't know if/whether he had seen the film.（过去完成） I wondered when she was going to America.（过去将来）注意：当主句是一般过去时，而从句表示的是客观真理，自然现象，科学原理，格言等，从句仍然要用一般现在时。例如： Eg: He said （that the earth moves round the sun. / that light travels much faster than sound.）The teacher told us （seeing is believing.）

九年级英语语法定语从句专题复习

定语从句专题复习定语从句（AttributiveClauses）在句中做定语，修饰一个名词或代词，被修饰的名词，词组或代词即先行词。定语从句通常出现在先行词之后，由关系词（关系代词或关系副词）引出。关系代词有：who,whom,whose(一般指人),that（指人或物）,which(指物)等。关系副词有：when（时间）,where(地点),why（原因）等。（1）关系代词引导的定语从句关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。 ①who,whom,that 这些词代替的先行词是人的名词或代词，在从句中所起作用如下： Ishethemanwho/that wantstosee you 他就是你想见的人吗（who/that在从句中作主语） Heistheman(whom/that)I saw yesterday. 他就是我昨天见的那个人。（whom/who/that在从句中作saw的宾语,可以省略） ②whose用来指人或物，（只用作定语，若指物，它还可以同ofwhich互换），例如：Theyrushedovertohelpthemanwhosecarhadbrokendown. 那人车坏了，大家都跑过去帮忙。 Pleasepassmethebookwhose/ofwhichcover（封面）isgreen. 请递给我那本绿皮的书。 ③which,that 它们所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等，例如：Rosalikesmusicthat/whichisquiteandgentle.（which/that在句中作宾语） Thisisthebook(that/which)I'mlookingfor.（which/that在句中作lookfor的宾语）（2）关系副词引导的定语从句关系副词可代替的先行词是时间、地点或理由的名词，在从句中作状语。 ①when,where,why 关系副词when,where,why的含义相当于“介词+which”结构，因此常常和“介词+which”结构交替使用，例如： Doyouremembertheday when Isawyou(你还记得我见到你的那一天吗) Beijingistheplace where（inwhich）Iwasborn.北京是我的出生地。 Isthisthereason why（forwhich）herefusedouroffer 这就是他拒绝我们帮助他的理由吗 ②that代替关系副词 that可以用于表示时间、地点、方式、理由的名词后取代when,where,why和“介词+which”引导的定语从句，在口语中that常被省略，例如： Hisfatherdiedtheyear（that/when/inwhich）hewasborn. 他父亲在他出生那年逝世了。 Heisunlikelytofindtheplace（that/where/inwhich）helivedfortyyearsago. 他不大可能找到他四十年前居住过的地方。（3）判断关系代词与关系副词方法一：用关系代词，还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语，就必须要求用关系代词；而不及物动词则要求用关系副词。例如：

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.

初中英语语法宾语从句试讲教案

宾语从句教学设计一、导入 1.复习什么是宾语。动词/介词后面的名词就是宾语。 I play basketball. We are talking about our homework.. 2.宾语从句就是在宾语的位置上放一个完整的句子。 3.I love that I can earn some coupons. 板书：He knows me. He knows what’s wrong with his wife. 说出2个句子的宾语。说出2个句子的宾语是词（词组）还是句子。第一个句子的宾语是一个词构成的，第二个句子的宾语是一个句子，我们称这种做宾语的句子叫宾语从句。在句子中充当宾语的从句叫宾语从句。其中he knows 叫主句，what’s wrong with him是从句。说出下面4个句子的主句和从句。 A．He said that he had a very good journey home. B．He asked if /whether they had come. C．He told me that the earth goes around the sun.

必考英语语法——限定性定语从句

2016年必考英语语法——限定性定语从句 1.that即可代表事物也可代表人，which代表事物；它们在从句中作主语或宾语，that 在从句中作宾语时常可省略关系词，which在从句中作宾语则不能省略。而且，如果which在从句中作“不及物动词+介词”的介词的宾语，注意介词不要丢掉，而且介词总是放在关系代词which的前边，但有的则放在它原来的位置 2.which作宾语时，根据先行词与定语从句之间的语义关系，先行词与which之间的介词不能丢 3.代表物时多用which，但在带有下列词的句子中用that而不用which，这些词包括all, anything, much等，这时的that常被省略 4.who和whom引导的从句用来修饰人，分别作从句中的主语和宾语，whom作宾语时，要注意它可以作动词的宾语也可以作介词的宾语 5.where是关系副词，用来表示地点的定语从句 6.when引导定语从句表示时间〔注〕值得一提的是，表示时间“time"一词的定语从句只用when引导，有时不用任何关系代词，当然也不用that引导 By the time you arrive in London, we will have stayed there for two weeks. I still remember the first time I met her. Each time he goes to besiness trip, he brings a lot of living necessities, such as towers, soap, toothbrush etc. 7.whose是关系代词，修饰名词作定语，相当于所修饰成分的前置所有格

初中英语语法：宾语从句

初中英语语法：宾语从句考察的三个要点：语序，时态，关联词。 1.定义：用作宾语的从句叫宾语从句。 2.构成：关联词+简单句。 3宾语从句的语序一定是陈述句语序。（who 作主语的从句本身就是陈述句语序） 4宾语从句在复合句中作主句的宾语，连接宾语从句的连词有 that（that在口语中常省略）。 whether，if，和连接代词what，which， who， whom及连接副词when， where， how， why。 He knew（that） he should study hard. 他知道他应该努力学习。 Can you tell me which class you are in？您能告诉我，您在哪一班吗？ He asked me if he could come in，他问我他是否能进来。 5.引导宾语从句的关联词有三类：（1）从属连词that.如：一般那情况下能够省略。 He told us that he felt ill. I know he has returned. 注： that在引导宾语从句时也并不是任何情况下都能够省略。在以下情况下，that不能省略。

1.Everybody could see what happened and that Tom was frightened. （and连接两个宾语从句，that宾语从句放在and的后面时，that不能省略。） 2.I know nothing about him except that he is from the south. （that引导的宾语从句作介词宾语时，that不能省略。） 3.That he ever said such a thing I simply don’t believe.（that从句位于句首时，that不可省略。）我简直不相信他曾说过这样的话。（2）从属连词if/whether.如： I doubt whether he will succeed. I don’t know if you can help me. （3）连接代词who，whom，whose，what，which，whoever，whatever， whichever 连接副词 where，when，how，why. Who or what he was，Martin never learned. I wonder what he’s writing to me about. I’ll tell you why I asked you to come.
