5.【名词性从句思维导图】【名词性从句从句考点梳理】6.考点清单一、名词性从句的种类、语法功能和引导词英语中从句主要分为三种：名词性从句（用从句代替名词）、定语从句（用从句代替形容词）、状语从句（用从句代替副词）。
名词性从句就是指从句在主句中充当名词成分，其功能相当于名词性词组。
1）根据从句在句子中不同的语法功能，名词性从句可分为：主语从句、宾语从句、表语从句和同位语从句。
2）根据名词性从句的引导词不同，可分为：that从句、if/whether从句和wh引导的疑问句（who/whom/whose/whoever/what/whatever/which/whichever/where/when/how/why等）。

英语必修一至四以思维导图的形式整理名词性从句
一、名词性从句：从句在主句中的成分相当于名词，又被称为名词性从句，在句子的功能相当于名词词组，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，名词性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。
连接词：
二、连词(5个)
1、that (本身无意义)
2、whether,if
3、as if ,as though
连接代词(10个)：what, whatever, who, whoever, whom, whomever, whose,whosever, which, whichever
连接副词(7个)：when, where, how, why, whenever, wherever, however
三、语序:
名词性从句的'词序与陈述句语序相同，即使是由特殊疑问词引导也要用陈述语句。
四、时态:
1、当主句的谓语动词是过去式时，宾语从句若不是一个客观事实或真理，其谓语动词也必须用某种过去时态。
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。
