名词性从句知识点在英语语法中，名词性从句是一个重要且复杂的部分。

它在句子中起着名词的作用，包括主语从句、宾语从句、表语从句和同位语从句。

接下来，让我们逐一深入了解。

一、主语从句主语从句即在句子中充当主语的从句。

例如，“What he said is true”（他说的是真的。

）在这个句子中，“What he said”就是主语从句。

引导主语从句的连接词主要有三类：1、从属连词：that、whetherThat he will come is certain （他会来是肯定的。

）这里的“that”在从句中不充当成分，只起引导作用。

Whether she will go there is not decided （她是否会去那里还没决定。

）“whether”表示“是否”。

2、连接代词：what、who、which、whose、whatever、whichever、whoever 等What you need is more practice （你需要的是更多的练习。

）“what”在从句中充当宾语。

3、连接副词：when、where、why、how 等When the meeting will be held has not been announced （会议何时举行还未宣布。

）需要注意的是，主语从句后置时，常用 it 作形式主语，而将真正的主语从句放在后面。

例如：It is unknown whether he will come （他是否会来还不知道。

）二、宾语从句宾语从句在句中充当宾语。

比如，“I know that he is a student”（我知道他是个学生。

）“that he is a student”就是宾语从句。

引导宾语从句的连接词与主语从句类似：1、从属连词：that（在口语或非正式文体中常省略）、whether、ifHe said （that) he was busyI wonder if/whether he will come2、连接代词：what、who、which、whose、whatever、whichever、whoever 等She asked me what I was doing3、连接副词：when、where、why、how 等Could you tell me how I can get there?宾语从句的时态要根据主句的时态来变化。

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, why1.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。

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。

______excited Jenny most是主语从句，从句中缺少主语，因此用关系代词what ；_____ she finally succeeded in ...是表语从句，从句中不缺少成分，因此用引导词that；______seemed to be the most difficult exam to him.是宾语从句，从句中缺少主语，因此用关系代词what ，故选B。

【点评】考查名词性从句，本题涉及主语从句，表语从句和宾语从句。

第一空处为主语从句，从句缺少主语，需用what引导；第二空所在句子是个定语从句，先行词为整个主句的内容，从句中缺少主语，需用which引导。

故选B。

名词性从句归纳一、名词性从句概说、结构与功能名词性从句是起名词作用的从句，其功能相当于名词词组，在复合句中可作主语、宾语、表语和同位语。

与之对应的名词性从句分别为主语从句、宾语从句、表语从句和同位语从句。

二、主语从句1、主语从句的类别●以从属连词that 引导的主语从句。

（从句位于句首，that通常不省略）→ That she will come to the conference has excited every one of us.●以从属连词whether 引导的主语从句。

（从句置于句首时一般不用if来代替whether）→ Whether we’ll go outing depends on the weath er.●以连接代词（what, whatever, who, whoever, which, whichever等词）引导的主语从句。

→ Whoever will be in charge of the project hasn’t been decided yet.【注】what 与that在引导主语从句时，what 不但起连接作用，而且还有具体意义，意为“所…的”，相当于the things that结构；而that则无词义。

即如果从句中不缺少主语或宾语时，选择that，否则用what。

●以连接副词（when，where, how, why 等词）引导的主语从句.→ When the new road is open to traffic has not been made clear.2、用it 作形式主语的主语从句注：以下几种特殊情况必须用it作形式主语：⑴ It is + adj. + that 从句常见的形容词有：necessary，right，likely，wrong，important，certain，clear，obvious，strange 等。

→ It is likely that there will be a snowstorm tomorrow.⑵ It is + noun + that 从句常接这种句型的名词有：a pity, a shame, good news, a fact, an honor, a wonder, no wonder 等。

名词性从句知识归纳名词性从句是指在句子中相当于名词的从句，主要包括主语从句、宾语从句、表语从句和同位语从句。

名词性从句不是修饰性从句，而是复合句中的主干。

e.g. That the boy failed again in the exam disappointed his mother. （主语从句）I know that he is writing his composition in his room. （宾语从句）The question is how we can finish it on time. （表语从句）The fact that some Chinese are still poor is really a great problem. （同位语从句）一、宾语从句---及物动词、介词、部分形容词（certain, sure, glad, afraid, frightened, happy, pleased, sad, sorry, surprised, upset, satisfied等）后e.g. I believe (that) he is honest. (that不充当从句内的任何成分，一般情况可省略)I’m glad that you are satisfied with your job. (that不充当从句内的任何成分)He doesn’t care if/whether it isn’t a fine day. (if/whether不充当从句内的任何成分) Please tell me what you want.

(whoever从当从句内的主语，意为“任何人”)【宾语从句要点拓展】1. that引导宾语从句时一般可以省略，若由and或or连接两个宾语从句时，第一个从句中的that可以省略，而第二个分句前的that不可省略。

【点评】考查名词性从句，本题涉及"特殊疑问词+ever"引导的主语从句。

3． is even more important is the earth cooled down, water began to appear on its surface.A. When; that; whenB. What; whether; asC. What; that; asD. lt; whether; as 【答案】 C【解析】【分析】这题考查从句的用法，第一空填what引导主语从句，在主语从句中what做主语，第二空填that引导表语从句，在表语从句中，as是引导时间状语从句，句意是：甚至更重要的是：随着地球的冷却，水开始出现在表面。

名词性从句在句子中起名词作用的句子叫名词性从句(Noun Clauses ）。

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。

根据从句在句子中的功能分根据从句的性质分 定语从句形容词性从句 主语从句名词性从句 宾语从句表语从句同位语从句状语从句副词性从句第一节 知识点讲解一．【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.Tips: 主语从句的that 绝对不能省去。

因为句子是不能做主语的，故用that 引导。

若去掉则没有了主语，而宾语从句的that 可省。

主语从句：That he is right is known to all of us.宾语从句：We all know (that) he is right.1. It 作形式主语和it 引导强调句的比较为了防止句子头重脚轻，通常把形式主语it 放在主语位置，真正主语搁置于句末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。

【英语】名词性从句知识点总结和题型总结（word）一、名词性从句1．______ will be in charge of the meeting has not been decided yet.A. WhatB. WhichC. ThatD. Who【答案】 D【解析】【分析】句意：谁将负责这次会议还没有决定。

______ will be in charge of the meeting是一个主语从句，从句中缺少主语，指人，故选D。

【点评】考查名词性从句，本题涉及who引导的主语从句。

2．While some behaviors may seem strange to you, remember you consider normal probably seems just as unusual to others.A. it; thatB. what; thatC. that; whatD. which; that【答案】 C【解析】【分析】句意：虽然有些行为对你来说可能很奇怪，但请记住，你认为正常的行为对别人来说可能也不寻常。

第一空为宾语从句，从句结构完整用that起连接作用，第二空为主语从句，从句中consider缺少宾语，应该用what，故选C。

【点评】考查名词性从句，本题涉及that引导的宾语从句和what引导的主语从句。

3．It has been pointed out ________ plays a vital role in driving away one's anxiety is one's sweet childhood memories.A. what thatB. whichC. thatD. that what【答案】 D【解析】【分析】句意：有人指出，驱除焦虑所起着至关重要的作用是童年美好的回忆。

本句时一个主语从句，it作形式主语，真正的主语为that what plays a vital role in driving away one's anxiety is one's sweet childhood memories.，主语从句中又有一个主语从句，且此主语从句中缺少主语，所以用what引导。

名词性从句1.概念：在从句中做主语/宾语/表语/起解释说明的作用（同位语）。

或者说是起名词作用的从句。

名词性从句一律用陈述语序。

2.分类：主语从句/宾语从句/表语从句/同位语从句3.连接词：⑴连接代词（who谁，主格；whom谁，宾格；whose谁的，所有格；what什么，which哪一个，whatever无论什么，whichever无论哪个，whoever无论谁）；⑵连接副词：when,where,how,why,⑶由if/whether引导，在句中意为“是否”。

用法：①句子成分完整，用that；②成分完整，意思不完整，用whether/if（是否），连接副词（when/where/why/how）/+ever；③成分不完整：指人用who（主/宾）whom（宾）whoever（主/宾）whomever（宾）；指物:用what（主/宾）。

4.详解：⑴主语从句：用来充当整句话的主语。

①主语从句在复合句中作主语的名词性从句，通常放在主句谓语动词之前。

that在从句中只起连接词作用且不可省略。

Whether she will come to the party is uncertain.A.陈述句做主语从句的转化方式，用that 引导。

The earth goes around the sun.=That the earth goes around the sun is a fact.B.一般疑问句转化为主语从句，只能用whether来引导，不能用if。

一般疑问句语序转化为陈述语序。

Will it rain tomorrow?=Whether it will rain tomorrow is not know.C.特殊疑问句变为主语从句，还是用原来的疑问词引导(特殊疑问句有两种结构，一种是疑问词＋一般疑问句；另一种是特殊疑问句本身就是陈述结构)What does she want?=What she wants is a trip to Lijing.她想要的是去丽江旅行。

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，名词性从句厅分为主语从句、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：1、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）。

2、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.（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.主要句型有：（1）It+be+形容词+that从句。

It is probable that he told her everything. 很可能他把一切都告诉她了。

（2）It+be+名词词组(no wonder, an honour, a good thing, a pity, no surprise, etc.)+that从句。
