名词性从句详解及练习
各类从句详解英语从句可以分为名词性从句、定语从句和状语从句三大类：下面我们逐一进行说明：一、名词性从句（主语从句、表语从句、宾语从句、同位语从句）主语从句、表语从句、宾语从句和同位语从句在复合句中的充当的成分和其名称相同，分别作主句的主语、表语、宾语和同位语。
上述这四种从句均被称为名词性从句。
所有的名词性从句均不能用逗号分开，并且它们都用相同的关联词，关联词如下：①主从连词：that (无意义), whether (是否), if (是否)（在句子中不充当任何成分）②连接代词：who (谁), whom (谁), whose (谁的), what (什么), which (哪一个)③连接副词：when (什么时候), where (什么地方), how (怎样), why (为什么)主从连词只起连接作用，连接代词和连接副词除了起连接作用外，还充当从句某一个成分。
另外，可以用whatever, whichever, whoever, who(m)ever等连接代词引导名词性从句，来加强语气。
下面分别对各种名词性从句进行介绍（一）主语从句（subject clause）在主句中用作主语的主谓结构称之为主语从句。
例如：That he will come to the discussion is certain.他来参加讨论是确定的。
That the moon moves round the earth is well known to all of us.月球绕地球转动，这是我们大家都熟知的。
When the meeting is to be held has not yet been decide.会议什么时候召开还没有决定。
主语从句放在句首，句子常常显得比较笨重，因此通常可以把it放在句首，作形式主语，而将主语从句放在后面。
例如上面的句子可以分别改写为：It is certain that he will come to the discussion.It is well known to all of us that the moon moves round the earth.It has not yet been decide when the meeting is to be held.下面再举一些例句：What they are after is profit.他们追求的是利润。

高中英语名词性从句知识点讲解和练习(无答案)
名词性从句定义:起名词性作用的从句，叫名词性从句( Noun Clauses )。
换言之，在英语的句子结构中，本来该由名词充当的主语、宾语、表语和同位语部分，换由一个句子来充当，这样的句子就是名词性从句。
分类:主语从句 ( subject clause )表语从句 ( predicative clause )宾语从句 ( object clause )同位语从句 ( appositive clause )从属连词 （3个）：that, if, whether连接代词 （10个）：what, which, who, whom, whose,whatever, whichever, whoever, whomever, whosever连接副词 （4个）：when, why, where, how名词性从句主要有三种结构:1、 以that 引导的名词性从句2、 以if/whether 引导的名词性从句3、 以特殊疑问词who, where, why, when, how, what 及wh -ever 引导的名词性从句 此外，as if/as though 也可引导表语从句。
具体用法见下表：名词性从句考点一that引导的名词性从句要点归纳：1、主语从句：a. that 引导主语从句时，that在从句中不充当成分，但不可以省略。
e.g. That she gets on well with her classmates is known to us all.That he was chosen made us very happy.b. 为了句子结构匀称，有时it被用作主语，that引导的主语从句则被置于主句的后面。
e.g. It is known to us all that she gets on well with her classmates.It is hoped that one day they will have enough animals to set them free.类似结构常见的有如下几种：1)It is clear/ certain/ likely/ right/ wrong/ surprising /true that …2)It is a pity/ shame/ good idea/ no wonder that ...3)It is said / told/ known / reported/ suggested/ believed/ hoped/thought that ...4)It seems/ happens that ...2、宾语从句a.that引导宾语从句时，that 在从句中不充当成分，一般可以省略，但在以下几种情况下不能省略：a)当that从句和主句谓语动词之间有插入语或者从句主语之间有插入语时，that不可省略。

名词性从句用法详解一、概说名词性从句，即指性质相当于名词的从句，它包括主语从句、宾语从句、表语从句和同位语从句。
从高考的考查的实际情况来看，名词性从句考得最多的是宾语从句，其次是主语从句，再次是表语从句，而同位语从句则很少考查。
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二、名词性从句的一般引导词1. 连接词that 只起连接作用，没有任何意思，也不充当句子成分，在宾语从句中可省略，但引导其他名词性从句时通常不省略。
I hope (that) you enjoy your holiday. 希望你假期过得好。
（宾语从句）That he likes you is very obvious. 很显然他喜欢你。
（主语从句）2. 连接词whether 也不充当句子成分，但有自己的意思，表示“是否”；引导宾语从句时，可换成if，但引导其他名词性从句时不能换成if。
如：He asked whether [if] I would show him the way. 他问我是否可以给他带路。
Whether it will do us harm remains to be seen. 是否对我们有害还要看一看。
(引导主语从句，不能用if 代替whether)3. 连接代词who(m), whose, which, what 等，均有各自的意义，在从句中作主语、宾语、定语等。
如：That’s what she wanted to do. （表语从句）Who will help us is not known. （主语从句）Tell me which one you like best. （宾语从句）4. 连接副词when, where, why, how 等，也各自有自己的意义，在从句中作状语。

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：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）。
（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.3、that引导主语从句时，不能省略。
e.g. That he suddenly fell ill last week made us surprised.（三）表语从句1、表语从句在复合句中作表语，位于系动词之后。
e.g. The question was who could go there.2、引导表语从句的连接词that有时可省去。
e.g. My idea is (that) we can get more comrades to help in the work.（四）宾语从句1、宾语从句在复合句中作宾语。
引导宾语从句的连词that一般可省略。
e.g. I hope (that) everything is all right.2、介词之后的宾语从句，不可用which或if连接，要分别用what或whether。
e.g. I’m interested in whether you’ve finished the work..I’m interested in what you’ve said.3、whether与if都可以引导宾语从句，常可互换。
但下面情况不能互换。
①宾语从句是否定句时，只用if，不用whether。
e.g. I wonder if it doesn’t rain.②用if 会引起误解，就要用whether。
e.g. Please let me know whether you want to go.（此句如果把whether改成if，容易当成条件句理解）③宾语从句中的whether 与or not直接连用，就不能换成if；不直接连用，可换。
e.g. I don’t know whether or not the report is true.I don’t know whether/ if the report is true or not.④介词后的宾语从句要用whether引导。
whether 可与不定式连用。
whether也可引导主语从句、表语从句、同位语从句，还可引导让步状语从句，以上均不能换成if。
但引导条件从句时，只能用if，而不能用whether。
e.g. It depends on whether we have enough time.They don’t know whether to go there.Please come to see me if you have time.（五）同位语从句同位语从句在句中作某一名词的同位语，一般位于该名词（如：news, fact, idea, suggestion, promise等）之后，说明该名词的具体内容。
e.g. I have no idea when he will be back.The fact that he had not said anything surprised everybody.练习：名词性从句一、判断下列各句哪句含有名词性从句，并指出是什么从句：1. China is no longer what it used to be.2.
