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。

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。
英语《名词性从句》语法知识及英语学习方法 名词性从句 一、that 从句 1、主语从句 （1）that从句作主语时，常用it作形式主语，常见的句型有： It+be+形容词（obvious, true, natural, surprising,good,wonderful,funny,possible,likely,certain,probable,etc.）+that从句 It+be+名词词组（no wonder, an honor, a good thing, a pity, no surprise, etc.）+that 从句 It+be+过去分词（said, reported, thought, expected, decided, announced, arranged, etc.）+that从句 （2）that可以省略，但that从句位于句首时，that不能省略。 2、宾语从句 （1）常见的可以接that从句作宾语的动词有see, say, know, imagine, discover, believe, tell, show, think, consider, be sure, be afraid等。在可以接复合宾语的动词
之后，如think, make, consider等，可以用it作形式宾语。 （2）That从句一般不能充当介词宾语，偶尔可作except, in 的宾语。 3、表语从句（that不可省略） 4、同位语从句 连词that引导同位语从句时，应在某些抽象名词之后，如：fact, hope, desire, thought, suggestion, idea, news, problem, possibility等，对前面的名词起补充说明的作用，that在从句中不担当任何成分，不能省略。 二、whether/if从句 1、在表语从句和同位语从句中只能用whether不能用if;当主语从句放于句首时，只能用whether不用if;当it作形式主语，主语从句放在句末时用whether或if 均可；discuss后引导宾语从句时，必须用whether。 2、在宾语从句中： （1）及物动词后：whether从句中不能有否定式，宾语从句为否定句时用if；if 不能与or not连用，但可以用whether or not；whether后可以加不定式。 （2）介词后：只能用whether,不用if。 三、特殊疑问词引导的从句 1、主语从句：特殊疑问词引导主语从句时，常用it作形式主语。 2、宾语从句 （1）常见的能接特殊疑问词引导的宾语从句的动词有see, tell, ask, answer, know, decide, find out, imagine, suggest, doubt, wonder, show, discuss, understand, inform, advise等。 （2）作介词宾语。 3、同位语从句、表语从句
高考英语语法专题——状语从句 1. 状语从句的类型 1) 时间状语从句：常见引导词有： when：表示主句和从句的动作同时或先后发生，强调点，表“就在那时；突然”。 while：常表示延续性动词或状态；while也可表示对比的转折。 as soon as：表示从句的动作一发生，主句的动作马上就发生。 hardly / scarcely … when；no sooner … than：表示“还没来得及……就；刚……就”。 directly, immediately, instantly：副词当连词用，表示“一……就”。 the moment, the mi nute, the second：充当连词，等于when / as soon as。 each time, every time, ne xt time, by the time等：也可以引导时间状语从句。 since：引导的时间状语从句，主句常用现在完成时，从句常用一般过去时。常用句型：It is + 段时间+ since从句，“自从……有多长时间了”。 until：常与not连用，表示“直到……才……”；Not until置于句首时，主句要部分倒装；在It is / was…that / who…强调结构中，须连在一起。 2) 让步状语从句：常见引导词有：although, though, even if, even though, as等。 3) 原因状语从句：常见引导词有： because：常用于回答why, 语气最强；强调原因，常与just, only等起强调作用的副词连用；可引导表语从句。 for：是个并列连词，一般不放在句首，常表示一种推测或解释，或用作附加说明，语气弱。 as, since：常译为“既然、由于”，表示十分明显的原因，语气较弱。 now that：表示“既然”的意思。 4) 地点状语从句：常见引导词有：where, wherever等。 5) 目的状语从句：常见引导词有：that, so that, in order that等。目的状语从句的谓语动词 常与情态动词连用，否则可能是结果状语从句。不可置于句首。目的 状语从句还可以用动词不定式来替换。 6) 结果状语从句：常见引导词有：that, so that, so … that, such … that …等。 7) 方式状语从句：由as, as if(though)等引导。 8) 比较状语从句：由than, as等引导。 9) 条件状语从句：由if, unless, so (as) long as, in case, once, a far as, on condition that等引 导。 2.注意： 1) 主将从现规则：在时间状语从句、条件状语从句、让步状语从句、方式状语从句中， 若主句用一般将来时，或是祈使句，或是含有情态动词的谓语形式，从句则用一般现在时表示将来时，如：You can join our club when you get a bit older. 2) 疑问词+ ever和no matter + 疑问词的区别：疑问词+ ever可引导名词性从句和让步 状语从句；no matter + 疑问词，只能引导让步状语从句。
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：
名词性从句 名词性从句包括宾语从句、主语从句、表语从句、同位语从句。 名词性从句一共有三种：1）that从句；2）whether从句；3）疑问词所引导的从句。 分项说明如下： 1）that从句 任何一个主语起首的陈述句前面冠以that，即成that从句。 He enjoys dancing. That he enjoys dancing. 2）whether从句 由可用yes/no回答的问句，即一般疑问句变化而成。 a) 问句有be动词时：Is he happy? Whether he is happy. b) 问句有一般助动词（can, will, may, should, ought to, must, have）时： Can he do it? Whether he can do it c) 问句有do, does, did等助动词时：主语与助动词还原，再将do, does, did去掉，后面的动词依人称和时态变化。 Did he come? Whether he came 3）疑问词所引导的从句 由疑问词（when, what, how, where, why）等引导的问句，即特殊疑问词，变化而成。 a) 问句有be动词时：What is he doing? What he is doing. b) 问句有一般助动词（can, will, may, should, ought to, must, have）时： 主语与助动词还原，前面保留疑问词。Where can he find it? Where he can find it. c) 问句有do, does, did等助动词时： 主语与助动词还原，前面保留疑问词，再将do, does, did去掉，动词依人称和时态变化。 What did he write? What he wrote. 注： Who, what, which为疑问代词，若在问句中作主语，变成名词性从句时，结构不变。 Who came here? Who came here. 名词性从句的功能： 1）作主语 Where he lives is still in doubt. 2）作及物动词的宾语 I know that he will go abroad in the near future. 3）作介词的宾语 a)此时仅能用whether从句或疑问词引导的名词性从句作宾语。That从句不可作介词的宾语。 I am worried about whether he can do it. prep. o. I am curious about how he’ll cope with the problem.

专题十一状语从句 状语从句在高考试题中由于其他从句的干扰，以及倒装句，强调句的介入，使得状语从句更为复杂。状语从句是一种副词性从句，通常由一个从属连词或一个起连词作用的词组引导。状语从句 1. 时间状语从句 常见的连词(组)： when, while, as, before, after, once, till, until, as soon as, now that, hardly ...when, scarcely ...when, no sooner ...than等。 可以引导时间状语从句的副（介）词（短语）或名词短语： directly, instantly, immediately, by the time, the moment, the second, the minute, the instant, every time, each time, next time, the last time等。 注意点如下： (1) when, while, as引导的时间状语从句 as表示“当……的时候”，往往和when/ while通用，但它着重强调主句与从句的动作或事情同时或几乎同时发生。when(at or during the time)既可以表示在某一点的时候，又可以表示在某一段时间内，主句与从句的动作或事情可以同时发生也可以先后发生。while强调一段时间，仅表示从句和主句的动作同时发生，并且有延续意义，该从句中的动词一般要用延续性动词，从句中常用过去进行时态或一般过去时态；当when表示a period of time时，两者可以互换。 She came up as I was cooking.(同时) 在我做饭时，她走了过来。 When we were at school, we went to the library every day.(在一段时间内) 当我们在学校时，每天都去图书馆。 While they were watching TV, I was preparing myself for the coming examination. 他们在看电视，而我在为即将到来的考试做准备。 Strike while the iron is hot. 趁热打铁。( 不可用as或when，这里的while意思是“趁……”) (2) before引导状语从句时的常见重点句型 ①It will (not) be ...before ... 还要……才，要不了多久就…… It was (not) ...before ... 过了……才(没多久就……) It was a long time before I got to sleep. 过了好长时间我才睡着了。 It wasn t long before he told me about the news. 没多久他就告诉了我那条新闻。 ②不等……就……；在……之前就…… The telephone rang off before I could answer it. 我还没来得及接电话，电话就挂断了。 ③刚……就…… He hardly entered the room before he heard the telephone ring. 他刚进屋电话铃就响了。
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
高考英语语法复习三:名词性从句 名词性从句相当于名词,可分别作主句的主语、表语、宾语和同位语。因此,名词性从句可分为主语从句、表语从句、宾语从句和同位从句。 (一引导名词性从句的连接词 1、连接代词:who, whose, whom, what, which。有词义,在从句中担任成分,如主语、表语、宾语、或定语等。 2、连接副词:when, where, why, how。有词义,在从句中担任成分,作状语。 3、连接词:that, whether, if, as if。that 无词义,在从句中不担任成分,有时可省略; if (whether, as if虽有词义,但在从句中不担任成分。 注意:连接代词与连接副词在句中不再是疑问句,因而从句中谓语不用疑问式。连接代词与连接副词在从句充当句子成分,连接词whether 和if(是否,as if(好象在从句中不充当句子成分,只起连接作用。根据句义,如果连接代词与连接副词,whether、if 和as if 都用不上时,才用that作连接词(that本身无任何含义。 (二主语从句 1、主语从句在复合句作主语。 e.g. Who will go is not important. 2、用it作形式主语,主语从句放在句末。 e.g. It doesn't matter so much whether you will come or not. 3、that引导主语从句时,不能省略。 e.g. That he suddenly fell ill last week made us surprised. (三表语从句 1、表语从句在复合句中作表语,位于系动词之后。 e.g. The question was who could go there. 2、引导表语从句的连接词that有时可省去。 e.g. My idea is (that we can get more comrades to help in the work. (四宾语从句 1、宾语从句在复合句中作宾语。引导宾语从句的连词that一般可省略。 e.g. I hope (that everything is all right. 2、介词之后的宾语从句,不可用which或if连接,要分别用what或whether。 e.g. I'm interested in whether you've finished the work.. I'm interested in what you've said. 3、whether与if都可以引导宾语从句,常可互换。但下面情况不能互换。 ①宾语从句是否定句时,只用if,不用whether。 e.g. I wonder if it doesn't rain. ②用if 会引起误解,就要用whether。 e.g. Please let me know whether you want to go.(此句如果把whether改成if,容易当成条件句理解 ③宾语从句中的whether 与or not直接连用,就不能换成if;不直接连用,可换。 e.g. I don't know whether or not the report is true.
状语从句 一．分类： such+n.+that（如果……以致）that（所以，因此）
让步状语从句：though/although不可同but连用。 though/although （虽然）however （可是）even though/if（即使） no matter+what/which/where/who/when =whatever/whichever/wherever/whoever/whenever （不论什么/哪一个/哪里/谁/何时） 比较状语从句：as （正如）as…as（和……一样）not as/so … as （不如……）than（比……更）the+比较级…+the+比较级（越……越……） 条件状语从句：if（假设）unless（如果不）so long as（只要）on condition that （如果） * 方式状语从句：as（像……那样地）just as（正像）as if（好像）as though（好像） 二．各种状语从句的简化方法： 1 作状语。 】 例：After she sang，she left the rich man's house．= After singing，she left the rich man's house．2．以as soon as引导的状语从句的主语若与主句主语一致时，从句等于on+doing sth.,作状语，此时的动词为非延续性动词。 例：Mary began to operate on the wounded soldiers as soon as he arrived at the village． = Mary began to operate on the wounded soldiers on arriving at the village． 3．时间状语从句和条件状语从句的主语和主句主语一致时，有时可简化为不定式作状语。 例：She stopped when she saw her husband．= She stopped to see her husband．If you want to understand the farmers，you must go to the countryside． = To understand the farmers，you must go to the countryside． 4．结果状语从句和目的状语从句的主语与主句主语一致时，可以简化为不定式作状语；若两者主语不一致时，则应简化为不定式的复合结构作状语。 例：He was so tired that he couldn't go any further．= He was too tired to go any further． I came here so that I could ask some questions．= I came here(in order) to ask some questions．5．以when，while引导的时间状语从句和以if引导的条件状语从句的主语若与主句主语一致时，从句等于when/while/if +doing sth.作状语，表示谓语动作发生在该状语动作的进行过程之中。 。 例：When he turned on the radio，he found it broken．= When turning on the radio，he found it broken．While she was walking along the street，she was hit by a car．= While walking along the street，she was hit by a car． 6．原因状语从句的主语与主句主语一致时，可简化为分词短语作状语。 例：Since l didn't know Chinese，I tried to speak to her in English．= Not knowing Chinese，I tried to speak to her in English． 注意：形容词短语也可作表示原因的状语，来代替原因状语从句，放在句首、句末均可，但一般应加逗号。 例：As he was thirsty and eager to get a little rest，he went into the tea-house． = Thirsty and eager to get a little rest，he went into the tea-house．
