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。

名词性从句讲解与练习
名词性从句讲解与练习导读：英语中的复合句（名词性从句，定语从句，状语从句），在各省份的单项选择中一般有2-3题。
因为高考中复合句是重点考查内容，所以我们应该学好复合句。
本章将重点讨论名词性从句。
一，名词性从句基础知识1，名词性从句基本概念：:在句中，充当主语，宾语，表语，同位语是一个句子，这个句子就叫名词性从句。
名词性从句可以分为主语从句，宾语从句，表语从句和同位语从句。
What matters is not winning but participating. （主语从句）Who will go there is not decided. （主语从句）That you want to be independent is only natural. （主语从句）温馨提示：我们常常用it作形式主语，而把主语从句放在句末。
It is not decided who will go there.It is only natural that you want to be independent.It is feared that many lives have been lost in the earthquake.I don’t know why he is always finding fault with me. (宾语从句动词+宾语从句)The singer made no comment on wether he had sold his story to a newspaper. (宾语从句介词+宾语从句)I am afraid that the doctors can do nothing to save the patient. (宾语从句be+adj.+宾语从句)I am not sure whether/if he will come. (宾语从句be+adj.+宾语从句)My homwtown is no longer what it used to be ten years ago. (表语从句)What I want to know is when we will have the sports meet. （表语从句）The truth is that I don’t get on with my flat-mate. （表语从句）同位语从句概念：位于名词（一般是抽象名词）news, fact,story, hope, wish, suggestion, proposal,idea, rumor等之后的从句，说明该名词的具体内容，这个从句就叫同位语从句。
名词性从句(宾语从句表语从句主语从句)讲解与练习
名词性从句（宾语从句表语从句主语从句）讲解与练习六大基本句型1主系表句型----- be （连合动词do）2、主谓宾----- do（vt）3、主谓----- do(vi)----(不及物动词)4、主谓宾补----do(vt)5、主谓宾宾---do(vt) 记双宾语的动词一定要记。
6、There be (不及物动词do)--------be (不及物动词)宾语从句定义：在主谓宾句型的宾语的位置上把做为名词的宾语扩展成一个be句型或者do句型。
可以用下列公式举行表示：主语+谓语+从句。
宾语从句的连词① that , ②whether(or not)或if; ③which(whichever),who(whoever)，whom(whomever) ，whose(whosever)，what(whatever); ④when(whenever)，where(wherever)，why，how(however); ⑤ how many, how much, how long, how often，how soon宾语从句的形式：1、主谓宾句型的宾语从句: 作为名词的宾语扩展成一个be句型或者do句型。
He knows the newsHe knows that the teacher is in classroom2、主谓宾宾---do(vt) 句型的宾语从句，把直接宾语变为一个be或do句型。
He tells me the newsHe tells the news to meHe tells me that she is a teacherHe tells that she is a teacher to me3、主谓宾补句型的宾语从句需要it来做形式宾语I find Chinese important主谓宾补I find that we make a quick decision about this matter important主谓宾语从句补I find it important that we make a quick decision about this matter主谓形式宾语补宾语从句I think it necessary that we take plenty of hot water every day .我以为每天多喝开水是有必要的.I feel it a pity that I haven’t been to the get-together.我没去聚会,感觉特殊遗憾.I have made it a rule that I keep diaries.我每天写日记成了习惯.4、宾语从句的省略形式：某些形容词后面可以带宾语从句，其形式为sb+be+形容词+that宾语从句：这一类形容词通常是表示人物的心理，情绪等状态的形容词如：sure, certain, glad, please, happy, sorry, afraid, satisfied, surpriseda. I am glad (that) you helped me.b、I am sure (that) you can pass the exam.1、I am glad of your help.2、I am sure about your exam.剖析：上面句子中介词后面所跟成分都做介词宾语。

名词性从句（宾语从句、表语从句、主语从句）六大基本句型1主系表句型----- be （连系动词do）2、主谓宾----- do（vt）3、主谓----- do(vi)----(不及物动词)4、主谓宾补----do(vt)5、主谓宾宾---do(vt) 记双宾语的动词一定要记。
6、There be (不及物动词do)--------be (不及物动词)宾语从句定义：在主谓宾句型的宾语的位置上把做为名词的宾语扩展成一个be句型或者do句型。
可以用下列公式进行表示：主语+谓语+从句。
宾语从句的连词① that , ②whether(or not)或if; ③which(whichever),who(whoever)，whom(whomever) ，whose(whosever)，what(whatever); ④when(whenever)，where(wherever)，why，how(however); ⑤ how many, how much, how long, how often，how soon宾语从句的形式：1、主谓宾句型的宾语从句: 作为名词的宾语扩展成一个be句型或者do句型。
He knows the newsHe knows that the teacher is in classroom2、主谓宾宾---do(vt) 句型的宾语从句，把直接宾语变为一个be或do句型。
He tells me the newsHe tells the news to meHe tells me that she is a teacherHe tells that she is a teacher to me3、主谓宾补句型的宾语从句需要it来做形式宾语I find Chinese important主谓宾补I find that we make a quick decision about this matter important主谓宾语从句补I find it important that we make a quick decision about this matter主谓形式宾语补宾语从句I think it necessary that we take plenty of hot water every day .我认为每天多喝开水是有必要的.I feel it a pity that I haven’t been to the get-together.我没去聚会,感觉非常遗憾.I have made it a rule that I keep diaries.我每天写日记成了习惯.4、宾语从句的省略形式：某些形容词后面可以带宾语从句，其形式为sb+be+形容词+that宾语从句：这一类形容词通常是表示人物的心理，情感等状态的形容词如：sure, certain, glad, please, happy, sorry, afraid, satisfied, surpriseda. I am glad (that) you helped me.b、I am sure (that) you can pass the exam.1、I am glad of your help.2、I am sure about your exam.分析：上面句子中介词后面所跟成分都做介词宾语。
我们完全可以将他们换成that+陈述句:3、I am glad of that you helped me.4、I am sure about that you can pass the exam.从语法上讲，以上的结构都是正确的。
但是，由于这样表达过于啰嗦，所以我们可以将其简化，省去介词，由于它们是宾语从句，所以连同that也可以省掉，因此，这是一种省略形式的宾语从句。
表语从句同样的道理，如果在主系表句型表语的位置上把表语变成一个be句型或者do句型，则称为表语从句。
①The question is difficult -------_the question is how we make money .主语系表主语系表语从句②The question is difficult -------- the question is that she is a thief主语系表语从句③The question is difficult -----the question is that there is a thief in the room主语系表语从句④事实是因为每个人都要生活------ the fact is because everyone must live小结：表语从句的引导词与宾语从句一样，规律与宾语从句一样，只不过称呼不同而已，因此掌握宾语从句以后，表语从句无需特别学习。
但要注意以下几点：1、不可以用if，而用whether 连接表语从句(as if 例外）。
False: The question is if the enemy is marching towards us.（错误）Right: The question is whether the enemy is marching towards us.（正确）2、that在表语从句中不可以省掉。
the question is that she is a thief3、注意比较That is because...”句型与that is why….句型“That is because...”与“That is why...”之间的不同在于“That is because...”指原因或理由，“That is why...”则指由于各种原因所造成的后果。
例如：1：He did not see the film last night.That is because he had to help his little sister with her homework.2、He had seen the film before.That is why he did not see it last night.(第一句话说明原因，第二句话说明结果)4、当主语是reason, fact，idea等抽象名词时，表语从句的连接词应该用that.①The reason is that he didn’t go to school②The traditional view is ____ we sleep because our brain is “programmed”tomake us do so.A when B. why C. whether D. that③You are saying that everyone should be equal, and this is ____ I disagree.A. whyB. whereC. whatD. how主语从句如果将主谓宾或主系表的主语扩展成为一个句子，称为主语从句：①The question is difficult ----that she makes money is difficult主语系表主语从句系表----- it is difficult that she makes mon ey形式主语系表真正的主语It= that she makes money 主语从句的结构：it is….that…..②the cat is a fact ----- that there is a cat in the room is a fact主语从句it is a fact that there is a cat in the room形式主语系表真正主语③he knows the news---- that he knows the news surprises meIt surprises me that he knows the news小结：主语从句的引导词与宾语从句一样，规律与宾语从句一样，只不过称呼不同而已，因此掌握宾语从句以后，主语从句无需特别学习。
但需要注意两点：1,主语从句有形式主语it2, 引导词if不能引导主语从句，只能用whether….(or not)If 不能引导主语从句———他明天是否上学还不知道 if he will go to school is unclear (错误) it is unclear if he will go to school（错误）Whether he will go to school is unclear It is unclear whether he will go toschool (正确)3、以下几点需要注意：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 was the football team and It had(who) helped the old man4、(1) 主系表的主语从句形式it +系+表+从句It is a fact that …事实是…It is natural that…很自然…(2)主谓宾的主语从句形式：it+谓语（及物动词）+宾语+从句（3）主谓的主语从句形式：it +谓语（不及物动词）＋从句It seems that…似乎…It happened that…碰巧…(4)主谓宾宾的主语从句形式：it +谓语+宾语+宾语+从句(5)主谓宾补的主语从句形式：it +谓语+宾语+补语+从句巩固练习1.
