that在从句中的用法小结
that除了用作指代代词以外，还可以用作连词引导名词性从句、状语从句，用作关系代词，引导定语从句。其用法如下：
一、that用作连词，引导名词性从句。
1. 引导宾语从句，that无实际意义，可省略。例如：
We must remember (that) the enemy will not perish of himself.
我们必须记住敌人是不会自行消灭的。
Kitty said (that) she would call again after supper.
凯蒂说她晚饭后再来
但是，当一个句子很复杂，句中有多个并列的宾语从句时，特别是第一个宾语从句特别长的情况下，后面宾语从句前的that不可省略。例如：
I wish (that) we could go sightseeing in Hangzhou this summer and that we could buy some books in Shanghai on our way back.
我希望今年夏天到杭州去玩玩，并在返回的路上到上海买点书。
2. 用于主语从句中，that一般不能省略。例如：
That we need more equipment is quite obvious.
我们需要更多的设备，这是很明显的。
That she is still alive is a consolation.
她还活着，这是使人感到宽慰的。
（以上两句中的that不能省）
有时主语从句较长，这时往往用it作形式主语，而把that从句移后。例如：
It is good you are so considerate.
你这么周到是很好的
It is certain that they will all eventually turn to socialism.
可以肯定他们最后都必将转到社会主义方面来。
3. 用在表语从句中，一般不可省。例如：

他的建议是我们把这片地开发成稻田。
But the fact remains that we are behind the other group.
现实情况仍旧是我们比别的组落后。
4. 用于同位语从句，that 不可省。例如：
We heard the news that our team had won.
我们听到了我们队赢了的消息。
The fact that he had not said anything surprised everybody.
他什么都没有说，这个事实让我们都感到惊讶。
5. 用于强调句，that不能省。例如：

我是上周在北京见到她的。
It was on this condition that I went.
是在这个条件下我才去的。
二、用于so that, so...that..., such...that..., 引导目的或结果状语从句。例如：

我们匆匆忙忙是为了听演讲不迟到。
I am so tired that I can not go on.
我如此疲劳以致于不能再继续了。
三、作关系代词引导定语从句，可以在从句中作主语或宾语，作宾语时可以省略。例如：
The students that had been watching started to applaud.（作主语）
一直在一旁观看的学生们鼓起掌来。
He is a man (that) you can safely depend on. (作宾语)
他是一个能放心信赖的人。
定语从句中的特殊用法 定语从句是起定语作用的,修饰,说明名词,代词或句子内容的从句,被定语从句修饰的词叫做先行词。引导定语从句，并在句中担任成分的词叫做关系代词或关系副词。定语从句是高考常考内容之一，使用时要尤其注意以下十种特殊用法。 一、只用that不用which的情况 1、当先行词是all, little, few, much, something,everything, anything, nothing, none等不定代词时。如：Everything that happened then was like a nightmare.当时发生的一切就像是一场噩梦。 I will tell him all that you told me at the ball.我要把你在舞会上跟我说的话全都告诉他。 2、当先行词被only, any, few, little, no, all, just, very（恰好的,表示强调）等词修饰时。例如：The only thing that we could do was to wait.我们能做的只是等待。 That’sthe very thing that we can do.那正是我们能做的事。 3、当先行词是序数词、形容词最高级或先行词被序数词或形容词最高级修饰时。例如：The first place that we visited was the Great Wall.我们参观的第一个地方是长城。 This is the best novel that I have ever read.这是我看过的最好的小说。 4、被修饰词为数词时。例如： Yesterday I caught two fishes and put them in a basin of water. Now you can see the two that are still alive.昨天我捉到了两条鱼，把它们放在一盆水里。你可以看到那两条鱼还活着呢。 5、主句是There be结构，修饰其主语的定语从句宜用that作关系代词修饰物。例句：There’sstill a room that is free.还有一个空房间。
宾语从句用法及其例句 宾语从句用法 时态： 1.主句用一般现在时，从句可用任意时态。 2.主句用过去时，从句用过去某个时态。 3.主句用过去时，从句是客观真理时，只用一般现在时。 一、宾语从句的连接词 从属连词 连接宾语从句的从属连词主要有that,if,whether. that引导表示陈述句的宾语从句, if和whether引导表示“是否”的一般疑问句的宾语从句. He told me (that he would) go to the college the next year 他告诉我他明年上大学. I don’t know if there will be a bus any more. 我不知道是否还会有公交车. Nobody knew whether he could pass the exam. 没人知道他是否会通过考试. 连接代词 连接代词主要有who, whom ,whose ,what ,whoever ,whomever ,whosever, whatever, whichever等. 连接代词一般指疑问,但what, whatever除了指疑问外,也可以指陈述.

定语从句中的that和which的用法 引导定语从句的关系代词有：that（指人或物）,which （指物）,who (指人）.指人时可用that或who ；指物时可用that 或which 。 That和which在从句里都可以做宾语和主语，做宾语时可以省略。指物时，两者一般可以互换，但在下列情况下只能用that： 1）当先行词是all ,any ,anything ,everything ,nothing 或被它们修饰时.例如： Is there anything that I can do for you 有什么可以为你做的吗? All that can be done must be done . 凡是能做的都必须做. 2）当先行词被形容词的最高级或序数词修饰时.例如：That is one of the most interesting books that are sold in the bookshop . 那是这家书店出售的最有趣的书之一. The first thing that we should do is to get some food . 我们该做的第一件事是弄点吃的. 3）当先行词有：the only ,the very ,the same ,the last 等修饰时.例如：
My necklace is not the only thing that's missing . 我的项链不仅是丢掉的东西. 4）当主句以who或which开头时,定语从句中引导词用that ,不用which 或who .以避免重复.例如： Who is the girl that is wearing a red coat 正穿一件红色外套的女孩子是谁? 5）当先行词既有人又有物时,用that .例如： The writer and his novel that you have just talked about are really well known . 你刚才谈起的那位作家以及他的小说确实很著名. 请注意: 以下几种只能使用which的情况: 1.引导非限制性定语从句，用which。 2.在“介词＋关系代词”结构中，关系代词必须用which。 如：The house in which we live is very large. 我们住的房子非常大。 This is the reference book of which the teacher is speaking. 这就是老师正在谈及的那本参考书。 注意：如果介词不放在修饰事物的限定性定语从句的句首，which就可换为that，例如：This is the question which/that we've had so much discussion about. =This is the question about which we've had so much discussion.

This is the pen which you want. 注意： (1)whom, which用作介词宾语时，介词可放在whom、which之前，也可放在从句原来的位置上；但在含有介词的动词固定词组中，介词只能放在原来的位置上。如：He is the very person whom we must take good care of. (2)引导非限制性定语从句时，必须用关系代词which，不用that,如：I have lost my bag, which I like very much. (3)关系代词在句中作主语时，从句的谓语动词的人称和数必须和先行词保持一致。 5.由that引导的定语从句中，that可以指人或物，在从句中作主语或谓语动词的宾语，但不能放在介词后面作介词宾语，如： The book that I bought yesterday was written by Lu Xun. 注意在下面几种情况下必须用that引导定语从句。 (1)先行词是不定代词all, few, little, much, something, nothing, anything等，如： All that we have to do is to practise English. (2)先行词被序数词或形容词最高级所修饰，如 The first letter that I got from him will be kept. (3)先行词被all, any, every, each, few, little, no, some等修饰，如 I've eaten up all the food that you gave me. 实用文档
一、基本概念： 在复合句中，修饰某一名词或代词的从句叫定语从句。如： Do you know the man who spoke at the meeting just now? That is the house where he lived ten years ago. 定语从句所修饰的词叫先行词；定语从句一般用关系代词或关系副词来引导，关系词放在先行词与定语从句之间起连接作用，同时又作从句中的一个成分。 引导定语从句的关系代词有：that, who, whom, whose, which; 关系副词有：when, where, why. 二、关系词的用法： （一）关系代词的用法： 1．作主语用who, which和that, 如： He is the man who/that lives next door. The train which/that has just left is for Shenzhen. 2．作宾语用whom, who, which, that, 如： The man (whom/who/that) we have just seen is a famous writer. Where is the book (which/that) I bought last week? 注：在非正式文体中，用于指人的关系代词who whom, that 通常可以省略，但在正式文体中通常用whom, 不可省略；用于指物的关系代词which和that 在非正式文体中也通常省略，但在正式文体中一般不省略。 3．作定语用whose, 如： (a) He is the man whose car was stolen last week. (b) It was a meeting whose importance I did not realize at that time. 注：“whose +名词中心词”这一结构在定语从句中既能作主语（如上a句），又能作宾语（如上b句）。whose 的先行词常用来指人，但有时也可以用来指具体事物或抽象概念，这时可以与of which 结构互换，词序是：“名词+of which”，如： They came to a house whose back wall had broken down.. (= the back wall of which) He’s written a book the name of which I’ve completely forgotten. (= whose name) 4．作表语只用that ，它既可以指人，也可以指物，但时常省略。如： He is no longer the man that he used to be. This is no longer the dirty place (that) it used to be. （二）关系副词的用法： 1．when 指时间，在从句中作时间状语，它的先行词通常有：time, day, morning, night, week, year 等。如： I still remember the time when I first became a college student.

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。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.

高中定语从句详解与练习 （一）定义及相关术语 1．定语从句：修饰某一名词或代词的从句叫定语从句。定语从句一般紧跟在它所修饰的先行词之后。 2．先行词：被定语从句修饰的词叫先行词。 3．关系词：引导定语从句的词叫关系词。 关系词有关系代词和关系副词。关系代词有that, which, who, whom, whose, as等；关系副词有when, where, why等。 关系词通常有下列三个作用：A、引导定语从句；B、代替先行词；C、在定语从句中担当一个成分。例如： The man who is shaking hands with my father is a policeman. 该句中， who is shaking hands with my father 是定语从句，修饰先行词the man，“who”是引导定语从句的关系词，代替先行词the man，在定语从句中作主语。 （二）关系代词引导的定语从句 1．who 指人，在定语从句中作主语。 The boys who are playing football are from Class One. 正在踢足球的男孩是一班的。Those who want to go to the museum must be at the school gate at 7 tomorrow morning. 想 去博物馆的人必须在明晨7点到大门口集合。 Yesterday I helped an old man who had lost his way. 昨天我帮助了一位迷路的老人。That is the teacher who teaches us physics. 那就是教我们物理的老师。2．whom 指人，在定语从句中做宾语，常可省略。 Mr Liu is the person ( whom ) you talked about on the bus. 刘先生就是你们在公共汽车 上谈论的那个人。 Li Ming is just the boy ( whom ) I want to see. 李明正是我想要见的男孩。 The professor ( whom ) you are waiting for has come. 你正在等的教授已经来了。 The girl ( whom ) the teacher often praises is our monitor. 老师经常表扬的那个女孩是我 们的班长。 注意：关系代词whom 在口语或非正式文体中常可用who 来代替，也可省略。 The man ( whom / who )you met just now is my old friend. 3．Which 指物，在定语从句中做主语或宾语，做宾语时常可省略。 Football is a game which is liked by most boys. 足球是大多数男孩所喜欢的运动。 The factory which makes computers is far away from here. 制造计算机的那家公司离这儿很远。 He likes to read books which are written by foreign writers. 他喜欢外国作家写的书。 The house which is by the lake looks nice. 湖边的那幢房子看上去很漂亮。 This is the pen ( which ) he bought yesterday. 这是他昨天买的钢笔。 The film ( which ) they went to see last night was not interesting at all. 他们昨晚看的电影一点意思也没有。 4．That 指人时，相当于who 或whom；指物时，相当于which.。在定语从句中作主语或宾语，作宾语时常可省略。
知识总结： 宾语从句的重难点主要有三点：引导词、语序和时态。 连词的选择 that和what 【高考示例】 1. We should respect food and think about the people who don’t have ___________we have here and treat food nicely.（2010福建卷） A. that B. which C. what D. whether 2. As a new graduate, he doesn’t know_____it takes to start a business here.（2010天津卷) A. how B. what C. When D. which 3. Before the sales start, I make a list of ______ my kids will need for the coming season. （2010山东卷） A. why B. what C. how D. which 4. I want to be liked and loved for ______I am inside. （2010北京卷） A. who B. where C. what D. how
考点解析： 以上四题均考查what引导的宾语从句，连接代词what在宾语从句中既起连接作用，又在从句中充当成分，即主语，宾语，表语或定语；而连接词that只起连接作用，在宾语从句中不充当任何成分，常可省略。所以我们在面对这类考题时： 首先，应判断从句部分是否缺主语，宾语，表语或定语。如果缺这些成分的话，首先考虑who, whom, what, which和whose等，但要区别后三者做定语时的用法区别。which 引导名词性从句时多表示疑问且要有一个明确的范围。 第二，如果题干中不需要填入代词，需要结合语境考虑是否需要填入疑问副词when, why, where, how, whether, if等。宾语从句表示不肯定或疑问，如“是否”、“是不是”、“能否”等，就用连词if/whether来引导。 第三，如果根据语境，宾语从句是个陈述句，不需要填入疑问副词，那就用连词that 引导。 例4的难点在于我想别人喜欢我是因为“我”的内在，也就是“我”inside的品质。只有what可以指代是什么。很多同学误选A，错误地用中文语言习惯去做英文题。whether和if 【高考示例】 … but it didn't matter that I would win or not．（NMET短文改错） 此题很显然是考查 whether和if引导宾语从句的差别。答案是将that改为whether。在使用whether和if引导宾语从句时，应注意以下几种情况：
定语从句中 which,that 的用法与区别 只能使用that的情况： 1.当先行词是nothing, something, anything, all, each等不定代词时。 e.g. Do you have anything that is important to tell me? 2.当先行词被all, any, some, no, not, every, each等修饰时。 e.g. I have some books that are very good. 3.当先行词被形容词最高级、序数词(包括last, next等)所修饰时。 e.g. This is the first book that I bought mysel f. The biggest bird that I caught is this bird. 4.主句是以which或who开头的特殊疑问句时 e.g. Which is the bike that you lost? 为了避免重复时用that Who is the woman that was praised at the meeting. 5.当先行词在从句和主句中都作表语时,无论先行词是人还是物. China is no longer the country that she was. 6.如有两个定语从句,其中一个已用which引导,另一个宜用that . Edison built up a factory which produced things that had never been seen before. 7.在there be句型中,只用that. He asked for the latest book (that) there is on the subject. 8.当先行词被the very, the last, the next, the only，the same 等词修饰时。 e.g. This is the very book that I lost yesterday. 9.当先行词又有人又有物时。 e.g. I won’t forget the things and the persons that I saw. 10. 先行词被all, every, no, any, little, some, much等修饰时。 I’ve read all the books that are not mine. 只能使用which的情况。 1、非限制性定语从句(即通常用逗号与主句隔开，如果去掉逗号，整个句子仍能表达完整的意义的定语从句)中。 e.g. Mary has a book, which is very precious. 2、在介词之后。 e.g. This is a house in which lives an old man. 3、当主句中的主语被that修饰时。 e.g. That dog which I found in the street belongs to Mary. 4. 非限定性定语从句修饰的是前面的整个句子，而且关系代词和关系副词前面有逗号, 用which开始的定语从句修饰前面半句 e.g. He will wear no clothes, which will distinguish（区分，辨别）him from his fellow men.
定语从句用法总结 一.定义：定语由一个句子来充当，那么这个句子就叫做定语从句。 eg: The old town has narrow streets and small houses that are built close to each other.其中划线部分为定语从句。 二.分类：分为限制性定语从句和非限制性定语从句，还有间隔性定语从句。 eg: is the school (that/which)we visited last year. （限制性定语从句） weather turned out to be very good,which was more than we could expect. （非限制性定语从句） days are gone when physical strength was all you needed to make a living.（间隔性定语从句） ] 注：定语从句和非限制性定语从句的区别 限制性定语从句无逗号隔开、不可缺少、起修饰限制作用；而非限制性定语从句有逗号隔开、可有可无、起补充说明作用。 三.构成：定语从句有先行词、引导词和从句构成。 先行词是定语从句所修饰限制的名词或代词。 引导词是用来引导定语从句的关系代词或关系副词。 eg: The old town has narrow streets and small houses that are built close to each other. 此句中先行词为：narrow streets and small houses, ( 引导词为：that，定语从句为：that are built close to each other 四．基本原则 定语从句中不能出现与先行词在意义上相一致的词 is the book that I like it best .(it 与book指同一物，所以要去掉。) 五．定语从句中常见考点：
浅谈that在从句中的用法 摘要：that在英语中是一个非常常见的单词，它之所以常见，不仅仅是 因为它是一个在生活中常常要用到它，更因为它的用法相当的多。因此，同学们在使用that这个单词时，总会出现这样那样的问题，特别是that 在从句中的使用,更是令同学们常常模棱两可，分辨不清。 关键词：that 用法 1.主语从句2. 宾语从句 3. 表语从句 4.同位语从句 5. 目的状语从句6.定语从句 that在英语中是一个非常常见的单词，它之所以常见，不仅仅是因为它是一个在生活中常常要用到的字，更因为它的用法相当的多。因此，同学们在使用that这个单词时，总会出现这样那样的问题，特别是that在从句中的使用,更是令同学们常常模棱两可，分辨不清。但考试中又常出现，让我们和学生都比较头痛。我觉得要解决这个问题，首先要让学生弄清that在所引导的从句中它的词性，然后结合实例分析，这样学生就可一目了然了。具体来说，that可作连词或关系代词。具体的作用如下： 一．that引导主语从句(subject clauses)，在句中充当主语的成分。that在句中无实义，但放在句首时不能省略： a．that the attempt to save her had succeeded became widely known. b．that they did not tell us about their problems is a pity. 这种结构主要是对that从句的内容进行强调，属正式文体，that the attempt to save her had succeeded和that they did not tell us about their problems在句中都分别作了主语。但为了避免显得头重脚轻，常把that从句移到句子后面，而把it放在句首，作形式主语，此时that可以省。上面两个句子就可改为: a. it is widely known (that) the attempt to save her had succeeded b. it is a pity (that) they did not tell us about their problems.
英语定语从句用法详解 在复合句中，修饰名词或代词的从句叫定语从句，被修饰的名词或代词叫先行词，引导定语从句的有关系代词who, whom, whose, which, that等和关系副词where, when, why等，关系代词和关系副词在定语从句中担任句子成份。 1.由who引导的定语从句中，who用作主语，如：This is the boy who often helps me. 2.由whom引导的定语从句中，whom用作宾语，如：The man whom you are waiting for has gone home. 3.由whose引导的定语从句中，whose用作定语，如：Do you know the girl whose skirt is white? 4.由which引导的定语从句中，which用作主语或谓语动词的宾语或介词的宾语，如： The room in which there is a machine is a work shop. The river which is in front of my house is very clean. This is the pen which you want. 注意： (1)whom, which用作介词宾语时，介词可放在whom、which之前，也可放在从句原来的位置上；但在含有介词的动词固定词组中，介词只能放在原来的位置上。如：He is the very person whom we must take good care of. (2)引导非限制性定语从句时，必须用关系代词which，不用that,如：I have lost my bag, which I like very much. (3)关系代词在句中作主语时，从句的谓语动词的人称和数必须和先行词保持一致。 5.由that引导的定语从句中，that可以指人或物，在从句中作主语或谓语动词的宾语，但不能放在介词后面作介词宾语，如： The book that I bought yesterday was written by Lu Xun. 注意在下面几种情况下必须用that引导定语从句。 (1)先行词是不定代词all, few, little, much, something, nothing, anything等，如： All that we have to do is to practise English. (2)先行词被序数词或形容词最高级所修饰，如 The first letter that I got from him will be kept. (3)先行词被all, any, every, each, few, little, no, some等修饰，如 I've eaten up all the food that you gave me. (4)先行词被the only, the very, the same, the last修饰时如 He is the only person that I want to talk with. (5)先行词既有人又有物时，如: They talked about persons and things that they met. (6)当句中已有who时，为避免重复，如：Who is the man that is giving us the class? 6.由when, where, why引导的定语从句，如: I don't know the reason why he was late. This is the place where we have lived for 5 years. I'll never forget the day when I met Mr Li for the first time. 注意：先行词是表示地点时，如果从句的谓语动词是及物的，就用that(which)，如果从句的谓语动词是不及物的，就用where引导。This is the house Which /that he has lived in for 15 years.(Where he has lived for 15 year.)
