高中英语名词性从句知识讲解以及练习题 附答案
高中英语名词性从句知识讲解以及练习题附答案一、名词性从句概述名词性从句是一种充当名词作用的从句，通常在主句中作主语、宾语、表语或同位语。
它通常由引导词（如that, whether, if, who, whom, whose, which, what等）引导，并且从句中含有一个主语和谓语。
名词性从句的种类有很多，包括主语从句、宾语从句、表语从句和同位语从句等。
下面我们将逐一介绍这些从句。
二、主语从句主语从句作为一个名词，通常位于句首，是一个句子，主要作用是作为主句的主语。
引导主语从句的词：What (什么)；Whether (是否)；If (是否)；That (那个)。
例句：What he said is true. (他说的是真的。
)Whether it will rain tomorrow is uncertain. (明天是否会下雨还不确定。
)If you go, I will go too. (如果你走，我也跟着走。
)That he is coming is good news. (他来的消息是好消息。
)注意：主语从句的谓语动词通常要用单数形式。
What引导的主语从句通常用来表示“事物”的概念。
三、宾语从句宾语从句是一个名词，通常位于主句的动词后面，作为主句的宾语。
它可以由常见的宾语从句引导词引导，例如whether, if, that, who, whom, whose, what, when, where, how等。
引导宾语从句的词：Whether (是否)；If (是否)；That (那个)；Who (谁)；Whom (谁)；Whose (谁的)；What (什么)；When (何时)；Where (何处)；How (如何)。
例句：I know that he is coming. (我知道他要来。
)I wonder if he is telling the truth. (我想知道他是否说了真话。
名词性从句知识点+练习题
1.名词性从句是什么？分为？2.名词性从句考连接词的选择。
那么连接词有哪些？怎么用？连词/ 连接副词：连接代词：比较：连接副词、连接代词Can you tell me how I can get to the railway station?I will tell you what our school looks like.如何使用各个连接词？(which几乎不出现，which在名词性(主、宾、表)从句中的用法Which boy she likes best is still unknown/is still a mystery)whether,if 区别：主语从句中，句首只能用whether.主语从句后置时，与表示选择意义的or连用，只能用whether. It does not matter whether …or…it作形式主语，真正主语在后边时，if/whether均可宾语从句时一般可通用，但if不能与not连用：I don’t know whether he is coming or not.表语从句、同位语从句只能用whether. The problem is whether the meeting will be held.介词后只能用whether It depends on whether you can do the work well.有无ever的区分____leaves the room last ought to turn off the light.____will give us a talk is unknown to us all.3. 主语从句–e.g. That she will do well in her exam is certain.常用it作形式主语It is certain that she will do well in her exam.4.宾语从句：–e.g. Do you know that he has joined the army?that可以被省略。
高中英语语法名词性从句(附练习题)
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。
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。
被强调部分指人时也可用who/whom。
例如：a) It is a pity that you didn’t go to see the film. 你不去看那场电影真可惜。
b) It doesn’t interest me whether you succeed or not. 我对你成功与否不感兴趣。
c) It is in the morning that the murder took place. 谋杀案是在早上发生的。
（强调句型）d) It is John that broke the window. 是John打碎的窗户。
（强调句型）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…It appears that… 似乎…(4) It ＋过去分词＋从句It is reported that… 据报道…It has been proved that… 已证实…It is said that… 据说…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。
高中英语高考名词性从句高频考点易混点整理(含练习和答案)
高考英语名词性从句高频考点易混点高频考点一：考查that与what的区别在引导名词性从句时，从属连词that一般要注意三个"不"：1.不省略。
当从属连词that引导的主语从句位于句首时，that不省略；that引导同位语从句时，一般不省略。
2.不作成分。
that 在名词性从句中不作任何句子成分。
3.无实义。
that 在名词性从句中没有实义。
在引导名词性从句时， what一般要注意一个"不",一个"有词义",一个"作成分"：1.不省略。
what 引导名词性从句时，不省略。
2.有词义。
what 引导名词性从句时，有词义。
一般表示"……的东西/事情等"，这一用法与that 的用法不一样。
3.作成分。
what 在引导名词性从句时，在从句中充当成分。
这一用法与that 的用法不一样。
例如：Nobody believed his reason for being absent from the class that he had to meet his uncle at the airport.该句中，that引导同位语从句，在句中不作任何成分，不能省略且无词义。
What the teacher said had a good effect on the children.what引导主语从句，在句中有词义。
高频考点二：it放在句首，真正的主语是that从句常用句型如下：① It+系动词+n.+ that从句;② It+系动词+adj.+ that从句;③ It+be+动词的过去分词形式（如said, reported, suggested等）+that从句；④ It+特殊动词（appear, seem, happen, matter, turn out, work out等）+that从句。
高频考点三：考查whether与if的区别whether与if在作"是否"讲时,是可以互换的。

高中英语名词性从句详细讲解与练习（附答案）
高中英语名词性从句详细讲解与练习在句子中起名词作用的从句叫名词性从句。
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，因此根据它在句中不同的语法功能，名词性从句又可分为主语从句、宾语从句、表语从句、同位语从句。
引导名词性从句的词叫做连接词，包括：1.连词（在名词性从句中只起连接作用，不作成分）2.连接代词（在名词性从句中作主语、宾语或表语）3.连接副词（在名词性从句中作状语）所有的名词性从句的语序都是陈述语序。
I主语从句：是在主句中作主语的从句。
它由连接词引导，通常位于谓语动词之前。
连接词：1.连词：在从句中不充当任何成分，常见的引导主语从句的连词有that, whether oThat he got the first prize excited him much.他获得一等奖一事使他非常兴奋。
It is doubtful whether we can get there on time.我们能否按时到达那儿还不确定。

专题三名词性从句名词性从句指在复合句中起名词作用的从句，它在句子中可作主语、宾语、表语或同位语。
名词性从句既是中学英语教课的要点，也是高考考察的热门。
一、名词性从句的分类名词性从句包含主语从句、宾语从句、表语从句和同位语从句。
其连结词有 that, if, whether；连结代词 who, what, which；连结副词 when, where, how, why 等。
考察热门一：对主语从句的考察主语从句在复合句中充任主语，它能够放在主句谓语动词以前。
但为了保持句子均衡，多半状况下可用it 作形式主语，而把主语从句置于句尾。
考察热门二：对宾语从句的考察宾语从句在句子中作及物动词或介词的宾语。
假如主句的谓语动词是及物动 make, find, see, think 等，则把宾语从句置于宾语补足语以后，用it 作形式宾语。
此外，某些作表语的形容词，如 sure, happy, glad, certain 等以后也能够带宾语从句。
考察热门三：对表语从句的考察表语从句在句子中作表语，位于主句中的系动词以后。

二、对名词性从句的考察应注意以下几点：考察热门五：考察名词性从句的语序和主从句时态名词性从句均应用陈说句语序，其时态要保持主从句时态一致性。
考察热门六：从语境和句子构造需要出发，选择适合的连词（I）连词that 和what：that 无实质意义，在从句中不充任任何成分，只起连结主从句的作用；如 that 指引宾语从句，常可省略；如指引主语从句、表语从句或同位语从句， that 不可以省略。
高中英语名词性从句知识点含练习
高中英语名词性从句知识点（含练习）基础回顾1.表语：表语用来说明主语的身份、性质、品性、特征和状态的，表语常由名词、形容词、副词、介词短语、动词的-ing、不定式、从句来充当，它常位于系动词(be, become, appear, seem,look,sound,feel,get,smell等词)之后。
如：Her job is selling computers. 此句表语为selling computers如果句子的表语也是由一个句子充当的，那么这个充当表语的句子就叫做表语从句。
2.同位语：一个名词(或其它形式)对另一个名词或代词进行解释或补充说明，这个名词(或其它形式)就是同位语。
如Mr. Smith,our new teacher,is very kind to us. 我们的新老师史密斯先生对我们很好。
Mr.Smith是主语our new teacher的同位语，指同一人。
同位语从句I heard the news that our team had won．我听到了我们队获胜的消息。
that our team had won 解释news的具体内容，是同位语正文一、定义在复合句中具有名词的性质的作主语、表语、同位语、宾语的从句叫名词性从句。
因此，我们把主语从句、表语从句、同位语从句和宾语从句这四种从句统称为名词性从句。
That he finished writing the composition in such a short time surprised us all他在很短的时间内写完作文让我们都很惊讶 (主语从句)The trouble is that she has lost his address. 麻烦的是她把他的地址搞丢了。
（表语从句）They have no idea at all where he has gone. 他们不知道他去什么地方了。
（同位语从句）Do you remember how he came? 你记得他怎么来的么？（宾语从句）二、语序名词性从句要采用陈述句语序。
高考名词性从句知识点总结及典型例题
高考名词性从句知识点总结及典型例题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 does n’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 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。
