(已经完成了工作)时态呼应否定转移had finished?4. 注意宾语从句中的时态呼应，当主句动词是现在时，从句根据自身的句子情况，而使用不同时态。例如：I know (that) he studies English every day. I know (that) he studied English last term. I know (that) he will study English next year. I know (that) he has studied English since 1998. 当主句动词是过去时态（could, would 除外），从句则要用相应的过去时态，如一般过去时，过去进行时，过去将来时等；当从句表示的是客观真理，科学原理，自然现象，则从句仍用现在时态。

名词性从句讲解 在复合句中起名词作用的从句叫做名词性从句。它包括主语从句、宾语从句、表语从句和同位语从句。名词性从句是中学阶段的一个重要语法项目，在历年的高考中几乎都涉及到，并且每年的命题各有变化。分析历届高考试题名词性从句考查的焦点主要有以下六个方面 1. 考查名词性从句的语序问题 2.考查引导词that与what的区别 3.考查it在名词性从句中作形式主语或形式宾语的用法 4.考查whether与if的区别 5. 考查名词性从句中的疑问词+ever引导的名词性从句与no matter+疑问词引导的状语从句的区别 6. 考查名词性从句的虚拟语气问题 语法要点剖析 一、名词性从句 主语从句、表语从句、宾语从句、同位语从句，在整个句子中所起的作用，相当于一个名词。因此，这四种从句通称为名词性从句。 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. 连接畐U词：whe n, where, how, why 1. 主语从句 作句子主语的从句叫主语从句。主语从句通常由从属连词that , whether , if和连接代词what, who, which , whatever , whoever以及连接副词how, when, where, why等词引导。that在句中无词义，只起连接作用；连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。例如： What he wants to tell us is n ot clear. 他要跟我们说什么，还不清楚。 It is known to us how he became a writer. 我们都知道他是如何成为一名作家的。 Where the En glish evening will be held has not yet bee n announ ced. 英语晚会将在哪里举行，还没有宣布。 有时为避免句子头重脚轻，常用形式主语it代替主语从句作形式主语放于句首，而把主语从句置于句末。主语从句后的谓语动词一般用单数形式。常用句型如下： (1) It + be + 名词+ that 从句(2) It + be + 形容词+ that 从句 (3) It + be + 动词的过去分词+ that 从句(4) It + 不及物动词+ that 从句 另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时，谓语动词要用虚拟语气“(should) +do”，常用的句型有： It is n ecessary (importa nt, n atural, stra nge, etc.) that … It is a pity (a shame, no won der, etc.) that … It is suggested (requested, propose d, desired, etc.) that … 2. 宾语从句 名词句用作宾语的从句叫宾语从句。引导宾语从句的关联词与引导主语从句表语从句的关联词大致一样，在句中可以作谓语动词或介词及非谓语动词的宾语。 1. 由连接词that引导的宾语从句 由连接词that引导宾语从句时，that在句中不担任任何成分，在口语或非正式的文体中常被省去，但如从句是并列句时，第二个分句前的that不可省。例如： He has told me that he will go to Sha nghai tomorrow. 他已经告诉我他明天要去上海。 We must n ever thi nk (that) we are good in everyth ing while others are good in nothing. 我们决不能认为自己什么都好，别人什么都不好。
名词性从句详解 名词性从句包括主语从句、表语从句、宾语从句、同位语从句。其关联词有连接词that，if，whether；疑问代词who，what，which和疑问副词when，where，how，why等。 一.语法讲解 1.主语从句 主语从句在句中做主语。它可以放在主句谓语动词之前，但多数情况由it作形式主语，而把主语从句放在主句之后。例如： Who did that is known to all. It is interesting that you should like him. 2.表语从句 表语从句在句中作表语，位于主句中的系动词之后。如： The question is who can complete the difficult task. 表语从句不能用if引导，但可用as if引导。例如： He looked as if he was going to cry． 3.同位语从句 同位语从句跟在名词后面，进一步说明该名词的具体内容。引导同位语从句的名词主要有fact，news，promise，idea，truth等。连接词用that（不用which），及连接副词how，when，where，why等。例如： His delay is due to the fact that the car went wrong halfway． The news that our team has won the match is true. She asked the reason why there was a delay． 4.宾语从句 1.宾语从句在句中作及物动词或介词的宾语。例如： We can learn what we did not know． He will talk to us about what he saw in the U.S. 如果主句的谓语动词是及物动词make，find，see，hear等，则把宾语从句置于宾语补足语之后，用it作为形式宾语。如： We find it necessary that we practise spoken-English every day． 另外，某些作表语的形容词，如sure，happy，glad, certain等之后也可带宾语从句。如： I am sure that he will succeed.

高考英语名词性从句讲解 一、概念： 名词性从句相当于名词词组，在复合句中起名词性作用。 分类：主语从句、表语从句、宾语从句和同位语从句。 引导名词性从句的1）连接词：that, whether, if; 2）关系代词：who, whom, whose, what, which, whatever, whichever; 3) 关系副词：when, where, how, why. 二、要点： 人物 主语：who, whoever what, whatever 宾语：whom, whomever what, whatever 名词性从句表语：whom what 定语：which what whose 状语when where why how whenever however wherever 不做成份：that if/whether as if /as though 三、基础知识学习： 1主语从句: 主语从句是在复合句中代替作主语的名词, 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.that 引导的主语从句 ①句首 That a round-trip to Mars would take more than a year and a half is estimated. That he misunderstood me is obvious. That引导主语从句，放句首，不做任何成分，不可省略。
②用形式主语it来引导句子 A. that引导主语从句放句首时，有时会为了避免头重脚轻，保持句子平衡，常用it做形式 主语，把真正的that引导的主语从句放句后。 It is strange that he made no answer. It is known to all that the earth is round. B. 用it做形式主语的主语从句结构 注意：i. 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.

适用文档 名词性从句解说 在复合句中起名作用的从句叫做名性从句。它包含主从句、从句、表从句和同位从句。名性从句是中学段的一个重要法目，在年的高考取几乎都波及到，而且每年的命各有化。解析届高考 名性从句考的焦点主要有以下六个方面 1.考名性从句的序 2.考引 that与 what 的区 3.考 it 在名性从句中作形式主或形式的用法 4.考 whether 与 if 的区 5.考名性从句中的疑+ever 引的名性从句与no matter+ 疑引的状从句的区 6.考名性从句的虚气法重点 解析 一、名性从句 主从句、表从句、从句、同位从句，在整个句子中所起的作用，相当于一个名。所以，四种从句通称名性 从句。 引名性从句的接可分三： 接： that, whether, if（不充任从句的任何成分） 接代： what, whatever, who, whoever, whom, whose, which. 接副： when, where, how, why 1.主从句 作句子主的从句叫主从句。主从句往常由附属that ，whether ，if和接代what ，who，which ，whatever ， whoever 以及接副 how， when， where， why 等引。 that 在句中无，只起接作用；接代和接副在句中既 保存自己的疑含、又起接作用，在从句中充任从句的成分。比如： What he wants to tell us is not clear.他要跟我什么，不清楚。 It is known to us how he became a writer.我都知道他是如何成一名作家的。 Where the English evening will be held has not yet been announced. 英晚会将在哪里行，没有宣告。 有防止句子重脚，常用形式主it取代主从句作形式主放于句首，而把主从句置于句末。主 从句后的一般用数形式。常用句型以下： （ 1） It + be +名+ that从句（2）It + be +形容+ that从句 （ 3） It + be +的去分+ that从句（4）It +不及物+ that从句另注意在主从句顶用来表示诧异、不相信、痛惜、理这样等气，要用虚气“(should) +do”，常用的句型有： It is necessary (important, natural, strange, etc.) that⋯ It is a pity (a shame, no wonder, etc.) that⋯ It is suggested (requested, propose d, desired, etc.) that⋯ 2.从句 名句用作的从句叫从句。引从句的关与引主从句表从句的关大概一，在 句中能够作或介及非的。 1.由接that引的从句 由接that引从句，that在句中不担当任何成分，在口或非正式的文体中常被省去，但如从句是并列句 , 第二个分句前的that不行省。比如： He has told me that he will go to Shanghai tomorrow.他已告我他明日要去上海。 We must never think (that) we are good in everything while others are good in nothing. 我决不可以自己什么都好，人什么都不好。 注意：在 demand、 order 、 suggest 、 decide 、 insist, desire, demand, request, command等表示要求、命令、建、决定等意的后，从句常用“（should ） + 原形”。比如：

名词性从句专题 一.概念：主语从句、表语从句、宾语从句和同位语从句在复合句中的作用相当于名词，因 此这四种从句被称为名词性从句。 ①主语从句 名词性从句共有四种: ②表语从句 ③宾语从句 ④同位语从句 我们先看几个句子： is not a big deal. ...Tell me what color the sea is today ...what you want to dream of tonight 终于你会发现每个爱情都危险ally you’ll find out that every love is dangerous. 二.知识点 1.主语从句：主语从句在整个句子中作主语。引导主语从句的连词有that，whether，if（是否）；连接代词who，what，which；连接副词when，where，how，why等。 请注意what，过去的高考中考的很多。 (1)主语从句中的that不充当句子的成分，只是单纯的连接词，通常不省略。分句置于句首时，that绝对不可以省略。 was obvious. that the driver could not control his car. （2）（参照必修3P 92）为了避免主语显得过长，可以用it作为句子的主语，把主语从句移到句子的末尾。（英语中有一种美，叫做尾重end-weight） 2.表语从句：表语从句出现在系动词后，充当表语。 The trouble is that we are short of money. Go and get your coat. It’s where you left it. 引导表语从句除了上述三类词外还有because, as if/ as though等等 The reason (why/for which…..) is that …… It/This/That is because…… 连系动词“appear, look, seem”的两个常用句型

完整版)高中英语名词性从句详解 名词性从句可以作为主句的主语、表语、宾语和同位语。它们分为主语从句、表语从句、宾语从句和同位从句。 宾语从句作为复合句中的主句及物动词的宾语，也可以作为介词或某些形容词的宾语。它不担任成分，只起连接作用。连接词可以是从属连词、关系代词、关系副词。从属连词包括that、whether、if；关系代词包括who、whom、whose、what、which；关系副词包括when、where、why、how。这些词既担 任成分，又起连接作用。 宾语从句的例子有：I think (that) you will like the pictures。He has e what he wanted to be ten years ago。I don’t know why Jane was late for school this morning。The teacher is pleased with what she said。I'm afraid that I can't go to the party. 在宾语从句中，由that引导的从句可以省略，但如果从句是并列句时，第二个分句前的that不可省略。另外，宾语从句中的时态要与主句呼应，如果主句动词是过去时态，从句则要
用相应的过去时态。如果从句表示的是客观真理、科学原理或自然现象，从句仍用现在时态。如果主语谓语动词为think、consider、suppose、believe、expect、guess、imagine等，其后的宾语从句若含有否定意义，一般要把否定词转移到主句谓语上，从句谓语用肯定式。 XXX。 It is often said that traveling broadens the mind。 I XXX I was determined to carry out the plan。 I consider it XXX。 XXX XXX of the plan。 XXX we need to ask ourselves is whether we can make good n in such a short time。
名词性从句 复合句包括两个或两个以上的主谓结构，其中一个是主句，另一个是从句(即在整个句子中作句子的一个成分，不能独立)。按照从句在句中的功能，可分为名词性从句、定语从句和状语从句。名词性从句包括主语从句、宾语从句、表语从句和同位语从句。因为这四种从句在整个句子中所起的作用相当于一个名词，因此，统称为名词性从句。名词性从句需由连接词引导，连接词主要有三类：从属连词、连接代词和连接副词。从属连词只起连接作用；连接代词和连接副词既起连接作用，又在从句中充当某一个成分。另外，名词性从句要用陈述语序。 考点一主语从句 常引导主语从句的连接词有从属连词：that(无词义)，whether／if(是否)；连接代词：what(什么；所……的)，who(主格，谁)，whom(宾格，谁)，which(哪一个)，whose(谁的)，whatever(无论什么)，whoever(主格，无论谁)，whomever(宾格，无论谁)，whichever(无论哪一个)等；连接副词：when(什么时候)，where(什么地方)，why(为什么)，how(怎样)等。 1．that引导的主语从句 that只起连接作用，无词义，在从句中不作成分，一般不能省略。如： That he will come and help us is certain．他来帮我们是肯定的了。 That pneumonia is a comrnon disease is known to all。 众所周知，肺炎是一种普通疾病。 2．whether／if引导的主语从句 whether引导的主语从句既可放在句首也可放在句尾，但if引导的主语从句只能放在句尾，前面需用it作形式主语。whether／
