高考英语语法之名词性从句

高考英语语法必考知识点：名词性从句1什么叫名词性从句从命名法的角度，名词性从句拆开来就是名词性的一个从句。

从句，顾名思义它是从属的成分，它是从属于主句存在的，不能单独存在，就类似于一个家里面一个大人带着一个小孩才能去玩，不能这个小孩自己单独去玩。

名词性顾名思义这个从句它是一个名词性的，就相当于这个从句它就是个名词，那么它在主句中要充当名词能充当的成分。

主句中名词的成分可以是主语、宾语、表语、同位语，所以名词性从句就是用一个句子在主句中充当主语或者宾语或者同位语或者表语的这样的成分，可以简单地记成名词性从句，包括主宾表同四大从句，这个就是名词性从句的本质和功能。

2名词性从句的难点(1)对名词性从句本质的理解和句子结构的划分名词性从句是镶嵌在主句中的，它不像定语从句，定语从句是主句穿了一个马甲，比如主谓宾，然后在主语后面加一个定语从句来修饰这个主语，而名词性从句不一样，它是直接用这个从句去做主句的主语或者做主句的宾语，所以在理解的时候名词性从句是没有办法拿掉的，一定要和主句一起来理解，那么这就是在划分名词性从句结构，分析句子结构的时候的一个难点。

(2)具体的引导词的用法没有办法直接把两个句子合在一起，就不得不说一个句子是从句，这样就一定要有标记词来告诉我们，这个句子是一个从句。

举个例子：我知道他迟到了。

在这句话中，我是主语，知道是谓语。

他迟到了这件事作为宾语。

所以他迟到了就是作为宾语从句。

在英语中不能直接说我知道他迟到了。

而是说我知道that他迟到了。

因为这个that的存在就把他迟到了这件事变成了一个名词性从句的成分，整个句子就相当于是一个名词作主句的宾语。

那么主语从句、表语从句和同位语从句也是一样的道理，需要在这个从句前面加一个引导词来表明这个从句的身份，给他戴个帽子。

所以在学习从句的时候的两个难点，一个是名词性从句，本质的理解，句子结构的划分，而另一个就是具体的引导词的用法，这一个是同学们在学习的时候一定要重点注意的。

高考英语语法填空之名词性从句一：知识储备1．确定是名词性从句设空处无提示词，先确定主句主谓结构；再确定设空和设空后的内容在主句中充当主语、宾语、表语或同位语。

2．利用2个技巧搞定名词性从句技巧1分析句子成分①缺少主语、宾语、表语：用连接代词what，who，whom，which，whatever，whose等。

②缺少状语(结合句意判断)：用连接副词where(表地点)，when(表时间)，how(表方式)，why(表原因)等。

③不缺成分，句意缺少“是否”：用if/whether。

④不缺成分且句子意义完整：用that。

技巧2句意语境巧解题有些引导词在句中有很鲜明的意义，如if“如果”，whoever“无论谁”，whatever“无论什么”，because“因为”，why“为什么”等。

结合句意翻译和语境，不难解决这类试题。

3．牢记what和that的区别①that没有词义，也不做任何成分，当从句意义完整，不缺任何成分时用that；②What在从句中表示“……的(东西)”(有时候可以不译)，在从句中充当主语、宾语、表语、定语等成分。

高考英语语法知识点：名词性从句1500字名词性从句是指在句子中充当名词的成分的从句。

名词性从句分为主语从句、宾语从句、表语从句和同位语从句。

在高考英语中，名词性从句是考查的重点之一，我们需要对名词性从句的结构和用法有透彻的理解。

下面是关于名词性从句的一些重要知识点：1.主语从句主语从句在句中充当主语的作用。

主语从句通常以that引导，也可以用whether或if 引导。

例如：- That he is guilty is certain.- Whether we will win the game is yet to be seen.- If it will rain tomorrow is still uncertain.2.宾语从句宾语从句在句中充当宾语的作用。

宾语从句通常以that引导，也可以用whether或if 引导。

需要注意的是，当主句的动词是说、tell、ask、think、believe、know等表示说话、思考、感觉的动词时，常用连词that引导宾语从句，但如果宾语从句的主语与主句的主语相同，可以省略连词that。

例如：- I know that he is a good student.- She asked me if/whether I had finished my homework.- He told her (that) he loved her.3.表语从句表语从句在句中充当表语的作用。

表语从句通常以that引导，也可以用whether或if 引导。

例如：- The fact that he didn't come is disappointing.- The question is whether we should proceed with the plan.- My concern is if/whether we have enough time.4.同位语从句同位语从句用来解释或说明前面名词的具体内容或意义。

名词性从句概念：起名词作用的从句叫名词从句。

它和名词一样，在句中可充当主语，表语，宾语和同位语。

名词从句包括主语从句，表语从句，宾语从句和同位语从句。

名词从句的引导词通常有：1. 连词that, whether, if.2. 连接代词what, whatever, who, whoever, whose, which等3. 连接副词when, where, how, whyI. 主语从句主语从句在从句中作主语，主语从句可以位于句首，但常见的主语从句多放在句末，句首则用形式主语it。

例如：1. That the earth is round is true. = It is true that the earth is round.2. Whether he will come hasn’t been decided. = It hasn’t been decided whether he will come.注意：连词that, whether在从句中不担任句子成分，只起连接作用，不能省略。

并且whether 引导主语从句时不能用if代替。

3. Who let out the news remained unknown. = It remained unknown who let out the news.4. How this happened is still a question.5. It is not clear when we will start.6. Why he didn’t come here is not clear to anyone. = It is not clear to anyone why he didn’t come here.7. Which is right isn’t known to us.注意：who, which, how, when, where, why在所引导的主语从句中可担任主语，宾语，状语，不能省略。

2023年高中英语语法：名词性从句运用及考点名词性从句的基本定义名词性从句，从字面意义上看，它在句子中相当于名字的作用。

名词性从句是历年高考的重点和难点也是热点。

它的英文名称是Noun clause。

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，根据它在句子中不同的语法功能，名词性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。

例如：1. The trouble is that I have lost his address.麻烦的是我把他的地址丢了。

2. My suggestion is that we should tell him.我的建议是我们应该告诉他。

3. You are not who I thought you were.你已不是我过去所想像的人。

4. The problem is who we can get to replace her.问题是我们能找到谁去替换她呢。

5. That’s where I first met her.那就是我第一次遇见她的地方。

6. It isn’t as if you were going away for ever.又不是你离开不回来了。

7. Now it was as though she had known Millie for years.现在好像她认识米莉已有好多年了似的。

8. It is not as though we were poor.又不是我们家里穷。

9. That he is still alive is a wonder.他还活着，真是奇迹。

10. That we shall be late is certain.我们要晚了，这是确定无疑的。

名词性从句分类根据从句在主句中所做的成分，名词性从句可以分为以下4种：例如：（1）That the seas are being over fished has been known for years.海洋正在被人们过渡捕捞，许多年来这已是尽人皆知的事情了。

高考英语语法：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,proba ble,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能够省略，但that从句位于句首时，that不能省略。

2、宾语从句（1）常见的能够接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。

在能够接复合宾语的动词之后，如think, make, consider等，能够用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。

高考名词性从句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、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、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：连词：that（无任何词意）whether,if（均表示“是否”表明从句内容的不确定性）as if ,as though（均表示“好像”，“似乎”）以上在从句中均不充当任何成分连接代词：what, whatever, who, whoever, whom,whose, which.whichever,whomever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.二. 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。

名词性从句第一节基本知识与基本概念【什么是名词性从句？】上一章，我们了解的是定语从句，加上我们以前了解的宾语从句和状语从句，好像“名词性从句”这个概念本身就和我们所熟知的概念不是一路货色。

没错。

请看下表：只是，在平时老师讲课时，形容词性从句和副词性从句并没有形成气候罢了。

相比之下，名词性从句由于“家丁兴旺”而大行其道。

但是，作为学生，我们有必要了解这些基本概念的来龙去脉。

【主语从句】顾名思义，主语从句在句子中作主语。

有时本身出现在主语的位置上，也有时出于句子结构的考虑退到句子的尾部，前面用形式主语it代替。

从句作主语时，谓语动词一般为单数形式。

如: What I saw was beyond any verbal description.That his hair was turning grey worried him a bit.Why the company denied the contract is still unknown.When and where the government will build a city square is under discussion.It is pretty annoying that a small part of the machine is missing.It remains to be seen whether the new novel will be well received.【宾语从句】在句子中作宾语的从句就是宾语从句。

由于这是同学们接触比较早的一种从句，应该问题不大。

所以在近年的高考题中，以宾语从句的知识作为考点的题目较少。

但是，宾语从句也有自己的特殊情况，如介词的宾语，形容词的宾语，宾语从句提前和并列的宾语从句等现象。

如：We assumed that there would be more than 100 guests.He told the police in detail what he saw and heard.Nobody is sure what humans will look like in a million years.That will depend on whether they can get the chance.Whether I will have the time I am not sure at the moment.The conductor complained that we were not gifted in singing and that he would never come again.【表语从句】表语从句的最重要脸谱就是它们应该出现在系动词的后面。

高考英语语法复习：名词性从句一、名词性从句名词性从句相当于名词，可分别在句中作主语、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、宾语从句和同位语从句。

从属连词that：在从句中不充当任何成分，也没有任何意思，只起连接作用，因此往往可以省略从属连词if, whether：在从句中不充当任何成分，有意义，不可以省略连接代词who, whoever, whom, whomever, which, whichever, what, whatever, whose：在从句中充当成分，有意义，不可以省略连接副词where, when, why, how：在从句中充当成分，有意义，不可以省略一、主语从句１.由从属连词引导的主语从句：①Whether the country should build a nuclear power station is something we must discuss.那个国家是否应该建立核电站……②That light travels in straight line is known to all .光以直线传播２.由连接代词引导的主语从句：①What we need is more time. 我们所需要的是……②Whichever book you choose doesn’t matter to me.无论你选哪本书……③Whoever comes will be welcome.无论谁来……３.由连接副词引导的主语从句：①When the plane is to take off hasn’t been announced.飞机什么时候起飞……②Where he has been is still a puzzle.他到过哪儿……③How much water is flowing can be measured easily.水的流量是多少……4.关于形式主语it①It + 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……It is likely that….很可能②It + be + -ed 分词+ that-从句It is believed that…人们相信……It is knownto all that…众所周知……It has been decided that…已决定……③It + 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……可应用于此句型的名词还有fact / shame / honor / question/pity等。

高考英语语法知识点从句高考英语语法知识点：从句高考英语考试中，从句作为一个重要的语法知识点经常出现。

从句是由一个主句和一个或多个从句构成的复合句。

在从句的结构和功能方面我们需要了解一些重要的知识点。

一、名词性从句名词性从句可以充当主语、宾语、表语和补语的功能。

根据不同的功能，名词性从句有三种形式：主语从句、宾语从句和表语/补语从句。

1. 主语从句：主语从句在句子中充当主语的角色，通常由由连接词that,whether/if引导。

例如：- That she is a talented musician is undeniable.（她是个有才华的音乐家是不可否认的。

）- Whether/if he can pass the exam is still uncertain.（他是否能通过考试还是未知数。

）主语从句常常出现在"It is/was + adj./n. + that"的句型中。

例如：- She asked me whether/if I had finished my homework.（她问我是否完成了作业。
