名词性从句
名词性从句是由if, whether, that 和各种疑问词充当连接词所引导的从句，其功同名词一样。
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：
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. 连接副词：when, 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 not 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。
英语语法：名词性从句语法讲解 时间：2016-10-08作者：来源：精品学习网 笔者在此就名词性从句中的几大易错点进行分析，希望对同学们有所帮助。 [关系代词和关系副词的误用] 例1 （2016·全国卷Ⅰ） My uncle is the owner of a restaurant close to that I live. 解析 that→where。本题考查宾语从句，引导词在从句中充当地点状语，所以将that改为where。 例2 （2015·全国卷Ⅱ） As natural architects， the Pueblo Indians figured out exactly thick the adobe walls needed to be to make the cycle work on most days. 解析 how。根据语境和空后的形容词thick可知应用how引导宾语从句，此处表示要弄清楚到底土坯房的墙需要“多”厚。故答案为how。 点拨若从句缺少主语、宾语、表语或定语，则考虑用关系代词；若从句缺少时间、地点、原因、方式等状语成分，则使用关系副词 （when/where/why/how）。 [if和whether的误用] 例3 He asked her the question if they can be friends. 解析 if→whether。question后为同位语从句，只能用whether来引导，故而将if改为whether。 例4 It doesn’t matter so much you will come or not. 解析考查主语从句。句意：你来还是不来，这不怎么重要。代词it作形式主语，真正的主语是whether引导的主语从句。 点拨在表达“是否”这一意思时，我们经常会用到whether和if，但以下几种情况只用whether不用if： 1. 在表语从句、主语从句、同位语从句中； 2. 在介词后的宾语从句中。如：It all depends on whether they will
语法复习专题（11） Unit11 名词性从句 一、考点聚焦 1、名词性从句中连接词的运用 名词性从句中的连接词有连词that / whether / as if，连接代词what / who/ which / whose / whatever / whoever / whomever / whichever，连接副词where / when / why / how / wherever / whenever。 （1）that的用法。 ①主语从句、表语从句、同位语从句中用that但不能省略。如： That they are good at English is known to us all. The problem is that we don’t have enough money. She expressed the hope that they would come to China one day. ②宾语从句中的连接词that有时可省有时又不可省，在以下几种情况中that不能省略：（A）当that从句和主句谓语动词之间有插入词语或者从句主语之间有插入语时，that不可省略；（B）当that 从句与另一名词性从句并列作宾语时，that不能省；（C）当that作介词宾语时，that不可省掉。如： He judged that,because he was a child, he did not understand wine Everyone knew what happened and that she was worried. The reason lies in that she works harder than the others do. ③that从句作主语和宾语时，可以用it 来替换成以下几种结构表达。 (A)It is clear/certain/likely/true/surprising that… （B）It is a pity/shame/good idea/no wonder that ...（C）It is said/reported/ believed/known/thought/suggested that … （D）It seems/happens that。如：It happened that I went out last night. It is said that China will win in the World Cup. ④that和what的区别。 that 引导名词性从句时，在主从句中不以当任何句子成分，也没有任何含义；而what 引导名词性从句时，在主从句中都要充当一定的句子成分，what可以分解成定语从句中的先行词 + 关系代词即常说的先行词 + that。如： It’s shame that he has made such a mistake. Do what he says. ⑤同位语从句与定语从句中that的区别。 同位语从句中的连词that只起连接作用，在从句中不担当任何句子成分；而定语从句中的关系代词that在句中做宾语或主语，宾语与先行词有修饰关系。如果句子是同位语从
高中英语状语从句讲解汇总 原因从句 除了下面A2，A3中所示各种类型外，这两种从句均可由as或because来引导。但是用as引导原因从句较为稳妥（参见A）；用because引导结果／原因从句较为稳妥（参见B）。 A 原因从句 1 由as／because／since 引导的原因从句： We camped there as／because／since it was too dark to go on． 我们在那里露宿是因为天太黑，不能再继续往前走了。 As／Because／Since it was too dark to go on，we camped there． [ 因为天太黑不能再继续往前走，我们就在那儿露宿了。 2 in view of the fact that可用as／since／seeing that来表示，但不能用because： As／Since／Seeing that you are here，you may as well give me a hand． 既然你在这儿，你就帮我个忙吧。 As／Since／Seeing that Tom knows French，he’d better do the talking． 既然汤姆懂法语，最好让他来谈。 3 在as／since／seeing that意指以前共知的或共知的陈述时，可用if来代替： ~ As／Since／Seeing that／If you don’t like Bill，why did you invite him 既然／如果你不喜欢比尔，你为什么邀请了他 注意：if so的用法： —I hope Bill won’t come． —If so（＝If you hope he won’t come），why did you invite him —我希望比尔别来。 —如果这样（=如果你希望他不来），你为什么邀请了他 关于if＋so／not，参见第347节。 ~ B 结果从句由because或as引导： The fuse blew because we had overloaded the circuit． 保险丝烧断了，因为我们使线路超载了。 He was angry because we were late． 他生气是因为我们来晚了。 As it froze hard that night there was ice everywhere next day． 因为那天晚上冷得厉害，所以第二天到处都是冰。 ~ As the soup was very salty we were thirsty afterwards． 因为这汤很咸，后来我们渴得厉害。

名词性从句精讲 在句子中起名词作用的句子叫名词从句(Noun Clauses）。名词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。That he will come h ere surprises me. I know that he will come here. The news is that he will come here.The new that he will come here surprises me. 一、名词性从句的相同点：1.结构 2.连接词 引导名词性从句的连接词可分为三类： 从属连接：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 二、四大名词性从句的剖析 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： That he suddenly fell ill last week made us surprised. 上星期他突然生病了让我们很惊讶。 Whether he will be able to come remains a question.他是否能够来仍然是一个问题。What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。Where the English evening will be held has not yet been announced.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 +形容词+主语从句It is very interesting that he likes such kind of books. （2）It + be +名词+主语从句It is a pity that he missed the lecture. （3）It + be +动词的过去分词+ that从句It is said that they have won the game. （4）It +不及物动词+ that从句It seems that something is wrong with the computer. 另注意在主语从句中用来表示必须、理应如此、建议、要求等语气时，谓语动词要用虚拟语气“(should) +do”，常用的句型有： It is necessary (important, natural, strange, etc.) that … It is suggested (requested, proposed, desired, etc.) that… 2.宾语从句 名词性从句用作宾语叫宾语从句，在句中可以作谓语动词或介词的宾语。引导宾语从句的连接词与

名词性从句精讲 来源：普特英语 在复合句中起名词作用的从句叫名词性从句，包括作主语从句、表语从句、宾语从句和同位语从句。 (1)主语从句 就是在复合句中作主语的从句。主语从句常用that, whether, who, whom, whose, what, which, when, where, how, why, whatever, whoever等引导。如： Whether he will be able to come remains a question. 他是否来还是问题。 That China is a great socialist country is well known. 众所周知，中国是一个伟大的社会主义国家。 注：为避免头重脚轻，使句子平衡，常用it作形式主语，而将主语从句后置。如上述第二 例常说成： It is well known that China is a great socialist country. 但是，由连接代词what, whatever, whoever等引导的主语从句一般不能用形式主语。如：What he found surprised me greatly. 他的发现使我非常吃惊。 Whoever is finished may rest. 凡是做完工的人都可以休息。 (2)表语从句 就是在连系动词之后作表语的从句。引导表语从句的连接除与引导主语从句的连接词外，还有as if，as though。如： The question is whether he is able to do it alone. 问题是他能否单独做这件事。 It looks as if (though) it is going to snow. 天好像要下雪似的。 注意：要区分以下句式： 1. that’s why+结果；that’s because+原因。 2. the reason why /for…is that… He is absent. That’s because he is ill. 他缺席，这是因为他生病了。 He is ill. That’s why he is absent. 他病了，这就是他缺席的原因。 The reason why he is absent is that he is ill. 他缺席的原因是他生病了。 (3)宾语从句 就是在复合句中作宾语的从句。引导这宾语从句的连接词与引导主语从句的连接词基本相同。如： They didn’t say which they wanted. 他们没有说他们想要哪一个。 I am sure (that) no harm will ever come to you. 我肯定你永远不会受伤害。 I was surprised at what has happened.我对发生的事感到惊讶。 注意：当think, believe, suppose等的疑问式后面跟连接代词或连接副词引导的宾语从句时， 习惯上将这些连接词置于句首，即“连接代/副词＋do you think /believe /expect＋宾语从句的
名词性从句的教学设计 陆丰林启恩纪念中学蔡少燕 一、学情分析 教学对象为高中二年级学生。学生已经进行了高中英语一年的学习，渐渐习惯了我的教法。他们会对课堂内容提出自己的疑惑和勇于阐述见解，并且从课内知识拓展到课外，通过多种渠道获取学习资源。不过，本班学生的水平参差不齐，有些差距还相当大。因此在教学过程中，布置的任务要兼顾各个层次的学生，使他们都有所收获。 二、教材分析 这是名词性从句语法课的第一次系统的学习，尽管之前在课本中已经让学生对名词性从句有了初步的理解，可是如何将已学的知识进行总结、归纳，找出其内在联系，找出其规律，并在此基础上去扩展知识、指导实践，从而使学生对知识掌握得更加牢固更加深刻是我这节课的重点。我的目标是根据学生水平和教学设计进行整合或增减，让不同层次的学生在课堂上都有所收获。 三、教学目标 Enable the students grasp the definition, kinds and use of noun clauses. 四、教学难点重点 1. How to distinguish the noun clauses. 2. How to tell the appositive clause from the attributive clause. 五、教具 Multi—media，a test paper 六、教学策略 环环相扣，设计紧凑。首先从简单句和名词性从句的对比入手，引出名词性从句的含义。并通过不同从句的基本特点让学生分辨属于哪一种名词性从句。接着，引导学生理解不同引导词的由来，并总结规律。然后，集中精力对付名词性从句的语序、时态及单复数概念的问题，让学生明白在运用名词性从句时要注意的一些问题。最后是名词性从句中.whether与if，同位语从句和定语从句的辨用。 在教学过程中，教师的基本任务是“导”，即起组织和引导的作用。教师应注意和研究如何启发诱导学生积极主动地参与教学活动。教师在教学中应指导学生自学，掌握自学方法，培养分析问题和解决问题的能力。 七、教学过程 Step1. Task I.什么叫“名词性从句”？ 名词性从句在功能上相当于名词 1.His job is important. What he does is important 2.This is his job This is what he does every day 3.I don’t like his job I don’t like what he does every day 4.I don’t know about the man, Mr. White I don’t know about the fact that he is a teacher. （这个部分主要是通过简单句中的一个单词让学生明白名词性从句就相当于一个名词的作用，不过就是由不同的引导词引导的一些句子放在不同词的位置上。这个部分我设计是让学
高中状语从句讲解+练习 状语通常由副词、介词短语、动词不定式、分词和从句等担当。例如： 1. Naturally , our grandparents were pleased to get our phone call . (副词) 2. We worked hard , from sunrise to sunset . (介词状短语) 3. To help my disabled aunt , I spend an hour working in her house every day . (不定式) 4. Seen from a distance , the farmhouse looked deserted . (过去分词) 5. I know how to light a camp fire because I had done it before .（原因状语从句） 状语从句主要用来修饰主句或主句的谓语。一般可分为九大类，尽管种类较多，但由于状语从句与汉语结构和用法相似，所以理解和掌握它并不难。状语从句的关键是要掌握引导不同状语从句的常用连接词和特殊的连接词即考点。现分别列举如下: 1．时间状语从句 常用引导词：when, as, while, as soon as, while, before, after, since , till, until 特殊引导词：the minute, the moment, the second, the instant, immediately , directly, every time, the day，no sooner …than, hardly …when, scarcely …when （1）Tell him I need to see him the minute he arrives. 他一到就告诉他我要见他。 （2）The children ran away from the orchard(果园) the moment they saw the guard.

She was standing exactly where you are standing now那时他就站在你现在站的地方。 Stay where you are.呆在原地别动。 Wherever you go, you should work hard. Sit anywhere you like 随便坐吧 3．原因状语从句

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

名词性从句teaching plan 一、学情分析 名词性从句是高中阶段学生接触到的较难的语法点，很多学生分不清楚名词性从句，定语从句和状语从句之间的区别，经常出现混用的现象。但在高考中名词性从句为必考项目，甚至在学业水平考试中都有要求，因此，学生复习名词性从句的用法有着重要意义，它对于学生分辨各种复合句有一定的指导作用，扫除名词性从句的障碍可以有助于学生学习其他的复合句，并对其书面表达和语法填空的提高有指导意义。 二、教学目标 1.知识与技能 A．复习名词性从句的种类及构成； B．正确辨识并使用名词性从句的连接词； C．复习it作形式宾语在句子中代替宾语从句。 2. 过程与方法 A．图解法 B．列举法 C．讲授法 D．演示法 3. 情感态度与价值观 A．培养学生的规范语言表达； B．让学生体会语言的灵活多变。 C．让学生体验学习的乐趣和成功的喜悦。 三、教学重、难点 1.名词性从句的作用； 2.正确判断并使用连接词； 3.名词性从句的表现形式； 4.It作形式主语和形式宾语的用法。 四、教学方法： 1.合作交流，小组讨论。 2.自主学习，独立思考。 3.探究学习。 五、渗透法制教育 教学步骤： Before class： 一．先学任务 1.复习五种简单句中的“主+谓”结构、“主+谓+宾”结构、“主+系+表”结构； 2.对比以下几个句子，区分其分别属于哪种从句。 1）What she said was right. （主从） 2）I have no idea how she did it.（同位语从句） 3）It’s a pity that you failed the exam.（主从）
状语从句 在复合句中作状语，位置灵活。 状语从句可分为时间状语从句，目的状语从句，条件状语从句，让步状语从句，地点状语从句，原因状语从句，方式状语从句，结果状语从句。 （一）时间状语从句 1.when, as, while a.when表时间，从句既可以用延续性动词，又可以用瞬间动词。 Eg: When I get there I will call you. 如果when引导的时状的主语与主句的主语相同，而从句的谓语又是be动词时，那么从句中的主语与be 可省。 Eg：When （you are）in trouble, you can ask her for help. 如果when引导的时状的主语与主句的主语相同时，往往可以用“when+分词”的形式代替该状从。Eg：When I came into the room(When coming into the room), I found the light was off. b.while表时间，从句需用延续性动词，或者主句的动作发生在从句的动作进行过程中。主句的谓语动词 通常是非延续性动词。 Eg: He came in while I was reading a book. I met her while I was in school. c. as表时间，与when相似，但侧重强调主从句动作同在时间点或同时间段进行。同时可表示主句的动作随着从句的动作的变化而变化。 Eg: He jumps as he sings. As the wind rose, the noise increased. 2.before(在……之前)与after（在……之后） Eg：See me before you leave. I saw them after I arrived. 3. till与until 肯定形式表示的意思是"做某事直至某时"。否定形式表达的意思是"直至某时才做某事"。 Eg: Wait till/untill I call you. 等着直到我叫你。 She didn't arrive till/until 6 o'clock.. 她直到6点才到 但是置于句首时只可用untill. Until you told me, I had heard nothing of what happened. 直到你告诉我以前，出了什么事我一点也不知道。否定形式有另外两种表达方式： (1)Not until …在句首，主句用倒装。 Man did not know what heat was until the early years of the 19th century. =Not until the early years of the 19th century did man know what heat was. (2)It is not until…that… He will not go to bed until his mother comes home. =It is not until his mother comes home that he will go to bed. 4. as soon as/the moment/the instant/the second/the minute/immediately和hardly/scarcely…when, no sooner…than a. as soon as/the moment/the instant/the second/the minute/immediately 表示主句和从句的动作同时发生。译为“一……就” Eg：As soon as she heard the news, she began crying. b. hardly/scarcely…when, no sooner…than都可以表示"一……就……"的意思，但主句谓语动词一般要用过去完成时，从句谓语动词要用一般过去时。 Eg：I had hardly / scarcely got home when it began to rain. I had no sooner got home than it began to rain.注意：如果hardly, scarcely 或no sooner置于句首，句子必须用倒装结构：Hardly / Scarcely had I got home when it began to rain. No sooner had I got home than it began to rain。 1. We called the First - Aid Center_______ the traffic accident happened. A. immediately B. shortly C.quickly D. hurriedly 2.
