名词性从句英语语法知识点汇总
名词性从句是在句子中起名词作用的句子。名词性从句的功能相当于名词词组，它在复合句中能担任主语、宾语、表语、同位语、介词宾语等。下面就是小编给大家带来的名词性从句英语语法知识点汇总，希望大家喜欢！
1 引导名词性从句的连接词
引导名词性从句的连接词可分为三类：
连接词：that,whether,if 不充当从句的任何成分)
连接代词：what, whatever, who, whoever, whom,
whose, which.
连接副词：when, where, how, why
不可省略的连词：
1. 介词后的连词
2. 引导主语从句和同位语从句的连词不可省略。
That she was chosen made us very happy.
We heard the news that our team had won.
比较：whether与if 均为是否的意思。但在下列情况下，whether 不能被if 取代：
1. whether引导主语从句并在句首
2. 引导表语从句
3. whether从句作介词宾语
4. 从句后有or not
Whether he will come is not clear.
大部分连接词引导的主语从句都可以置于句末，用it充当形式主语。It is not important who will go.
It is still unknown which team will win the match.
2 名词性that-从句
1)由从属连词that引导的从句叫做名词性that-从句。That只起连接主句和从句的作用，在从句中不担任任何成分，本身也没有词义。名词性that-从句在句中能充当主语、宾语、表语、同位语和形容词宾语，例如：
主语：That he is still alive is sheer luck. 他还活着全靠运气。宾语：John said that he was leaving for London on Wednesday. 约翰说他星期三要到伦敦去。
表语：The fact is that he has not been seen recently. 事实是近来谁也没有见过他。
同位语：The fact that he has not been seen recently disturbs everyone in his office.
近来谁也没有见过他，这一事实令办公室所有的人不安。
形容词宾语：I am glad that you are satisfied with your job.
你对工作满意我感到很高兴。
2)That-从句作主语通常用it作先行词，而将that-从句置于句末，例如：
It is quite clear that the whole project is doomed to failure. 很清楚，整个计划注定要失败。
Its a pity that you should have to leave. 你非走不可真是件憾事。用it作形式主语的that-从句有以下四种不同的搭配关系：
a. It + be +形容词+ that-从句
It is necessary that…有必要……
It is important that…重要的是……
It is obvious that…很明显……
b. It + be + -ed 分词+ that-从句
It is believed that…人们相信……
It is known to all that…从所周知……
It has been decided that…已决定……
c. It + be +名词+ that-从句
It is common knowledge that………是常识
It is a surprise that…令人惊奇的是……
It is a fact that…事实是……
d. It +不及物动词+ that-分句
It appears that…似乎……
It happens that…碰巧……
It occurred to me that…我突然想起……
3 名词性wh-从句
1)由wh-词引导的名词从句叫做名词性wh-从句。Wh-词包括who,
whom,. whose, whoever, what, whatever, which, whichever等连接代词和where, when, how, why等连接副词。Wh-从句的语法功能除了和that-从句一样外，还可充当介词宾语、宾语补语和间接宾语等，例如：
主语：How the book will sell depends on its author. 书销售如何取决于作者本人。
直接宾语：In ones own home one can do what one likes. 在自己家里可以随心所欲。
间接宾语：The club will give whoever wins a prize.
俱乐部将给得胜者设奖。
表语：My question is who will take over president of the Foundation. 我的问题是谁将接任该基金会主席职位。
宾语补足语：She will name him whatever she wants to. 她高兴给他起什么名字就取什么名字。
同位语：I have no idea when he will return.
我不知道他什么时候回来。
形容词宾语：Im not sure why she refused their invitation. 我尚不能肯定她为什么拒绝他们的邀请。
介词宾语：That depends on where we shall go.
那取决于我们去哪儿。
2)Wh-从句作主语也常用先行词it做形式主语，而将wh-从句置于句末，例如：
It is not yet decided who will do that job.
还没决定谁做这项工作。
It remains unknown when they are going to get married. 他们何时结婚依然不明。
4 if, whether引导的名词从句
1)yes-no型疑问从句
从属连词if, whether引导的名词从句是由一般疑问句或选择疑问转化而来的，因此也分别被称为yes-no型疑问句从句和选择型疑问从句，其功能和wh-从句的功能相同，例如：
主语：Whether the plan is feasible remains to be proved. 这一计划是否可行还有等证实。
宾语：Let us know whether / if you can finish the article before Friday. 请让我们知道你是否能在星期五以前把文章写完。
表语：The point is whether we should lend him the money. 问题在于我们是否应该借钱给他。
同位语：They are investigating the question whether the man is trustworthy. 他们调查他是否值得信赖。
形容词宾语：Shes doubtful whether we shall be able to come. 她怀疑我们是否能够前来。
介词宾语：I worry about whether he can pass through the crisis of his illness. 我担心他是否能度过疾病的危险期。
2)选择性疑问从句
选择性疑问从句由关联词if/whether…or或whethe…or not构成，例如：
Please tell me whether / if they are Swedish or Danish. 请告诉我他们是瑞典人还是丹麦人。
I dont care whether you like the plan or not.我不在乎你是否喜欢该计划。
5 否定转移
1) 将think, believe, suppose, expect, fancy, imagine等动词后面宾语从句的否定词转移到主句中，即主句的谓语动词用否定式，而从句的谓语动词用肯定式。
I dont think I know you. 我想我并不认识你。
I don t believe he will come. 我相信他不回来。
注意：若谓语动词为hope,宾语从句中的否定词不能转移。
I hope you werent ill. 我想你没有生病吧。
2) 将seem, appear 等后的从句的否定转移到前面。
It doesnt seem that they know where to go.
看来他们不知道往哪去。
It doesnt appear that well have a sunny day tomorrow.
看来我们明天不会碰上好天气。
3) 有时将动名词，介词短语或整个从句的否定转变为对谓语动词的否定。
I dont remember having ever seen such a man.
我记得从未见过这样一个人。(not否定动名词短语having…)
Its not a place where anyone would expect to see strange characters on the street.
在这里，人们不会想到在街上会碰上陌生的人。
(anyone 作主语，从句中的谓语动词不能用否定形式。)
4) 有时状语或状语从句中否定可以转移到谓语动词前。
The ant is not gathering this for itself alone. (否定状语) 蚂蚁不只是为自己采食。
He was not ready to believe something just because Aristotle said so. (否定because状语) 他并不因亚里斯多德说过如何如何，就轻信此事。
She had not been married many weeks when that mans younger brother saw her and was struck by her beauty. (否定状语many weeks) 她结婚还不到几个月，这个人的弟弟就看见她了，并对她的美貌着了迷。

初中英语语法宾语从句讲解，专项练习及答案注意！宾语从句小口诀： 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； 陈述句转化that引，一般疑问句用if/whether, 特殊问句疑问词，引导词后陈述式。 一、基本讲解 1 概念:在句中担当宾语的从句叫宾语从句，宾语从句可作谓语动词的宾语，也可做介词的宾语。eg, He said he was good at drawing. (动词宾语) He asks him how long Mike has been down . (动词宾语) Miss Zhang is angry at what you said. (介词宾语) 2.连接词 (1) .陈述句转化成宾语从句时，引导词用that,口语中常常省略。 e.g, She told me (that) she would like to go with us. (2)以whether 或if 引导的宾语从句, 主要用来引导一般疑问句意思或选择疑问句意思的宾语从句，从句同样是陈述语序 eg, I wonder if /whether u have told the new to Li Lei . 注意：一般情况下，whether 和if 可以互用，但有些情况例外。 a. 当从句做介词的宾于是只用whether 不用if eg, We are talking about whether we'll go on the pinic. b. 引导词与动词不定式或not 连用时，只用whether. eg, Please let me know what to do next.

高中英语语法定语从句总复习 郴州资兴三中李俊才 定义：用来说明主句中某一名词或代词（有时也可说明整个主句或主句中一部分）而起定语作用的句子叫 作定语从句。 一、关系带词引导的定语从句 1. 关系代词用来指代先行词是人或物的名词或代词 句子成分用于限制从句或非限制性从句只用于限制性从句 代替人代替物代替人或物主语Who which 主语Whom which that 宾语Whose (=of whom) Whose (=of which) that 例１：This is the detective who came from London. 例２：The book which I am reading is written by Tomas Hardy. ２．关系代词的用法 (1) 如果先行词是all, much, anything, something, nothing, everything, little, none等不定代词，关系代词一般只用that，不用which。例如： All the people that are burst into tears.（所有人都迸出眼泪。） (2) 如果先行词被形容词最高级以及first, last, any, only, few, most, no, some, very等词修饰，关系代词常用that,不用which, who，或whom。 (3) 非限制性定语从句中，不能用关系代词that,作宾语用的关系代词也不能省略。 There are about seven million people taking part in the election, most of whom、are well educated. (4) which还有一种特殊用法，它可以引导从句修饰前面的整个主句，代替主句所表示的整体概念或部分 概念。在这种从句中，which可以作主语，也可以作宾语或表语，多数情况下意思是与and this 相似，并可以指人。例如： He succeeded in the competition, which made his parents very happy. (5) that可指人或物，在从句中作表语，（指人作主语时多用who）仅用于限制性定语从句中。
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
名词性从句知识点总结经典(1) 一、名词性从句 1．He took a trip to Beijing last week and ________ he saw at the Forbidden City impressed him deeply. A. that B. how C. what D. which 【答案】 C 【解析】【分析】句意：上周他到北京旅行了，他在故宫所看到的给他留下了深刻的印象。分析句子结构可知，连词and后为一个名词性从句，因此应该使用what引导，且what在从句中作主语，故选C。 【点评】考查名词性从句，本题涉及what引导的主语从句。 2．It has been pointed out ________ plays a vital role in driving away one's anxiety is one's sweet childhood memories. A. what that B. which C. that D. that what 【答案】 D 【解析】【分析】句意：有人指出，驱除焦虑所起着至关重要的作用是童年美好的回忆。本句时一个主语从句，it作形式主语，真正的主语为that what plays a vital role in driving away one's anxiety is one's sweet childhood memories.，主语从句中又有一个主语从句，且此主语从句中缺少主语，所以用what引导。故选D。 【点评】考查名词性从句，本题涉及what引导的主语从句。 3．________ is known to us all that the old scientist, for ________ life was hard in the past, still works hard in his eighties. A. As; whose B. It; whose C. As; whom D. It; whom 【答案】 D 【解析】【分析】句意：我们都知道，那位老科学家，过去生活很艰苦，到了八十多岁还在努力工作。第一空it is known to us all that…是个固定句型，意为“众所周知…”；第二空为介词+关系代词引导的定语从句，先行词the old scientist指人，作介词for的宾语，只能用whom，故选D。 【点评】考查名词性从句和定语从句，本题涉及固定句式it is known to us all that…和whom引导的限制性定语从句。 4．Some people believe _______ has happened before or is happening now will repeat itself in the future.

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 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. What 与that 在引导主语从句时的区别 What 引导主语从句时在句时在从句中充当句子成分，如主语.宾语.表语，而that 则不
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.

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.

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.）
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：
（精华版）初中英语语法基本从句汇总从句的共同特点 从句是指在一个句子中充当一个成分的句子，充当什么成分就叫什么从句，如：充当宾语就叫宾语从句，充当定语成分就叫定语从句。 从以上定义中我们可以得出关于从句的一个最大特点：从句是句子。 从句的共同特点：1.从句都有自己的连接词2.从句都是陈述语序(陈述语序就是主语在前，谓语在后，如：He is a teacher主语He在谓语is之前，因此是陈述语序，而Is he a teacher?主语He在谓语is之后，因此不是陈述语序。) 1宾语从句 宾语从句是指在一个句子中充当宾语的句子，如：He said that he wanted to be a teacher when he grew up. 宾语从句的特点： ①宾语从句有自己的连接词 ②宾语从句用陈述语序 ③宾语从句的时态 1
①宾语从句的连接词：宾语从句的连接词包括that、if/whether(是否)、特殊疑问词。 ②宾语从句的语序; A.宾语从句的连接词后加陈述语序(主语在前，谓语在后),如：I want to know if he can come tomorrow B.当连接词本身又是宾语从句的主语时，后面直接加谓语动词，如：She asked me who had helped him. ③宾语从句的时态，只要记住以下口诀就可以了“主现则从任，主过则从过，客观真理一般现” A.主现则从任：主句如果是一般现在时，则从句根据时间状语需要从八种时态中任选一种，如：1.He tells me he likes English very much(一般现在时) B.主过则从过：主句如果是一般过去时，则从句根据时间状语需要从四种带“过”字的时态中任选一种，带“过”字的时态分别是如：一般过去时，过去进行时，过去将来时，过去完成时。 如：He told me that he liked playing football(一般过去时) C.客观真理一般现:客观真理永远用一般现在时。 如：1.He says the moon goes around the earth. 2状语从句 2
名词性从句知识点总结 在句子中起名词作用的句子叫名词性从句(Noun Clauses）。名词性从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，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。 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。被强调部分指人时也可用who/whom。例如： a) It is a pity that you didn’t go to see the film. 你不去看那场电影真可惜。 b) It doesn’t interest me whether you succeed or not.我对你成功与否不感兴趣。 c) It is in the morning that the murder took place.谋杀案是在早上发生的。（强调句型） d) It is John that broke the window.是John打碎的窗户。（强调句型） 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… It appears that…似乎… (4) It ＋过去分词＋从句 It is reported that…据报道… It has been proved that…已证实… It is said that…据说… 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： 正确表达：It is said that President Jiang will visit our school next week. 错误表达：That President Jiang will visit our school next week is said. （3）It happens/occurs…结构中的主语从句不可提前。例如： 正确表达：It occurred to him that he failed in the examination. 错误表达：That he failed in the examination occurred to him. （4）It doesn’t matter how/whether …结构中的主语从句不可提前。例如： 正确表达：It doesn’t matter whether he is wrong or not.
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. D．He asked me how he could get to the nearest post office. 总结：。。是主句，剩下的是由that，if，how引导的宾语从句。 初步认识了宾语从句，下面我们开始了解宾语从句的三要素 引导词（连接词） 语序 时态 1)从属连词that引导陈述句宾语从句，在口语或者非正式语中可以被省略 比如上面四句话中的A,C就是that引导的陈述句的宾语从句。如果省略掉that，该如何修改。（让学生口头修改） A．He said that he had a very good journey home. C．He told me that the earth goes around the sun. 2）由从属连词whether, if 引导一般疑问句的宾语从句，表示“是否”，比如上面的B就是由if引导的宾语从
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
