That you don’t like him is none of my business.你不喜欢他不管我的事。
(2)形式主语it替代主语从句位于句首,that引导真正的主语从句会放到句子的后面。

如:It is necessary that … 有必要 .....It is clear that … 很清楚.....It is likely that … 很可能.....It is important that … 重要的是.....类似的形容词还有:strange; natural; obvious; true; good; wonderful; possible; unlikely; quite; unusual; certain; evident; worth-while; surprising; interesting; astonishing, etc.例如:It was really astonishing that he refused to talk to you.It is essential that he should be here by the weekend.It seems obvious that we can not go on like this.It is necessary that you (should)master the computer.It is important that a student learn English well.It' s clear that they badly need help.It is likely that a hurricane will arrive soon.知识拓展:在“It is necessary / important/surprising/strange/unthinkable/unbelievable/incredible+that 从句”这类主语从句结构中,从句中谓语动词常用(should) +动词原形”,形式,即要用虚拟语气should 可省略。

I wondered how he could make such rapid progress in French.
注意:若从句表达的是客观真理,仍用一般现在时
It is said that they have won the game.
常用过去分词:said, believed, reported, hoped, claimed, known, announced, suggested
此句型可转换成另一结构:
主语 + be + 过去分词 + to do / to have done

它可以充当主语、宾语、表语和同位语等多种语法成分。
名词性从句在英语语法中占据重要地位,掌握不同种类和用法对于语言的正确运用至关重要。

名词性从句和主语从句的区别
名词性从句和主语从句的区别名词性从句和主语从句是英语语法中两个重要的从句类型,它们在使用和功能上有着一些区别。
本文将对名词性从句和主语从句的区别进行详细介绍。
一、名词性从句的定义和功能名词性从句是在句子中充当名词的作用,可以作为主语、宾语、表语或同位语。
名词性从句通常由连接代词(如what, who, whom, which, whoever, whatever)或连接副词(如when, where, why, how)引导。
名词性从句在句子中的功能类似于名词,用于表达陈述、提问、建议、愿望、要求、目的、理由等。
二、主语从句的定义和功能主语从句作为句子的主语,从句中的谓语动词所表示的是主句中的主谓关系。
主语从句通常由连接代词(如what, who, whom, which, whoever, whatever)或连接副词(如when, where, why, how)引导。
主语从句在句子中的功能是充当整个句子的主语,用于表达主谓关系,而且不能省略。
三、名词性从句和主语从句的区别1.位置不同:- 名词性从句可以出现在句子的主语、宾语、表语和同位语等位置,位置较为灵活。
- 主语从句只能作为句子的主语出现,位置不可变。
2.引导词不同:- 名词性从句常由连接代词或连接副词引导。
- 主语从句也常由连接代词或连接副词引导,但通常只由连接代词引导。
3.结构不同:- 名词性从句在结构上是完整的句子,包含主语、谓语和其他成分。
- 主语从句在结构上只包含主语部分,谓语动词在主句中。
4.可替换性不同:- 名词性从句可以被代替为一个单词或一个词组。
- 主语从句在句子中起到主语的作用,不能被代替。
四、名词性从句和主语从句的例句说明1. 名词性从句的例句:- I don't know what he said.(主语从句作宾语)- Tell me where she lives.(主语从句作宾语)2. 主语从句的例句:- What he said is interesting.(名词性从句作主语)- Where she lives is a mystery.(名词性从句作主语)综上所述,名词性从句和主语从句在使用和功能上存在区别。
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之主语从句解析

引导词语分成三种:连词:that,whether;疑问代词:who, what,which,whose,whatever,etc.连接副词有:when,where,why,how,wherever,etc.1、that引导的主语从句这个词不同于其它的连词,在主语从句中没有什么意义,也不充当什么成分,只是作为一个简单的连词,但是还不可以省略掉。
这是经常使用的一种主语从句,但是这种主语从句很少用于句首,除非是强调句或者谓语过长。
例如说:That prices will keep going up is certain in 2009.一般情况下,that引导主语从句时,常用it作形式主语,而将正真的主语that从句放在句尾。
这样的结构如下:(1)it+be+形容词+that从句如:It is natural that people should have different opinions.(2)it+名词+that从句如:It's a wonder that they are still alive.(3)it+动词+that从句如:It happened that he didn't go out because of the bad weather that day.(4)it+动词被动语态+that从句如:It's said that there was a big earthquake in Wen chuan several days ago.2、连接代词或者是连接副词引导的主语从句。

【高中英语】英语名词性从句:主语从句,宾语从句
【高中英语】英语名词性从句:主语从句,宾语从句1.主语以及主语从句先看两个句子:第一个:thereasonsareclearnow。
第二个问题:他为什么现在要谋杀他的妻子。
在这组例子中,第一个句子是名词thereasons充当主语,句型简单,意思清晰:原因已经清楚了。
在第二个句子中,我们发现主语的部分由一个从句whyhemurderedhiswife 来担当。
注意它的构成是:引导词+陈述句。
根据这个从句出现的位置(出现在主语的位置),我们就把它称为主语从句。
其实质就是原先名词的部分,变成了一个相应的从句形式,来充当主语的角色。
通过以上例句,我们对主语从句有了更好的理解。
引导主语从句的引导词主要包括:that、what、what、how等疑问词。
2.宾语以及宾语从句同样,让我们先看两句话:第一个:hehasmadeclearthefacts。
第二个:他把昨天做的事情讲清楚了。
在这组例子当中第一句名词thefacts做的是句中动词make的宾语。
我们来给这个句子变一下形:他把事实弄清楚了fact是本句的宾语,clear是对fact的一个补充说明。
这就叫做宾语补足语。
说白了就是把宾语的信息补充完整。
明白了之后,第二句就不难理解了。
宾语词的一部分变成句子的形式,它位于宾语的位置,因此被称为宾语从句。
这类从句出现在及物动词之后。
它的构成是:引导词+陈述句。
能够引导宾语从句的引导词:that(在这里要注意到that引导宾语从句的时候,that 可以省略掉)、whether、what、how等疑问词。
