1.名词性从句主语从句宾语从句表语从句同位语从句2.形容词性从句——定语从句3.副词性从句——状语从句从句共分为三种类型：1. 主语从句主语从句有三种类型：➢that引导➢连接代词、副词引导➢关系代词what或whatever引导1.1 由that引导的主语从句主语从句通常由it作形式主语，将that引导的从句置于句尾。
that在句首时不能省略，但在it作形式主语时，后置的从句中的that在口语中有时省略。
1.1 由that引导的主语从句一般情况下把主语从句放在句首是很少见的，除非为了强调或谓语太长时才作这样的安排。
例如：That she became an artist surprised all of us.It surprised all of us that she became an artist.她成为一名艺术家，这使大家很惊讶。
1.1 由that引导的主语从句①It+be+形容词/名词+that从句例如：It is certain that we will win the game.我们肯定会赢这场比赛。

【高中英语】高中英语知识点：主语从句主语从句的概念：如果一个句子在复合句中充当一个主语，那么这个句子就是主语从句。
主语从句通常由从属连词that，whether，if和连接代词what，who，whichwhatever，whoever以及连接副词how，when，where，why等词引导。
that在句中无词义，只起连接作用。
主语从句用法：1、主语从句的引导词：主语从句通常由连词that和whether、相连接代词或相连接副词以及关系代词型what鼓励：如：thatheisstillaliveisawonder.他还活着，真是奇迹。
whenwearrivedoesn'tmatter.什么时候至没关系。
whatweneedismoney.我们需要的是钱。
whatiwanttoknowisthis.我想要晓得的就是这一点。
whethertheywouldsupportuswasaproblem.他们是否会支持我们还是一个问题。
2、主语从句与形式主语it：有时为了考虑句子平衡，通常在主语从句处使用形式主语it，而将真正的主语从句移至句末。
这分三种情况：(1)对于以连词that鼓励的主语从句，通常用形式主语代主语从句：(2)对于以连接代词(副词)引导的主语从句，可以使用形式主语代主语从句，也可直接在句首使用主语从句：例如：whethertheywouldsupportuswasaproblem.他们与否可以积极支持我们还是一个问题。
itwasaproblemwhethertheywouldsupportus.他们是否会支持我们还是一个问题。
(3)对关系代词型what鼓励的主语从句，通常不必形式主语，总是主语从句放到句首：如：whatweneedismoney.我们需要的是钱。
whatiwanttoknowisthis.我想要晓得的就是这一点。
(4)如果句子是疑问句，则必须用带形式主语it的结构：例如：isittruethatheisthegirl'sfather?他就是那女孩的父亲，就是真的吗？howisitthatyouarelateagain?你怎么又迟到了？3、连词that的省略问题：引导主语从句的连词that有时可省，有时不能省，其原则是：若that鼓励的主语从句轻易坐落于句首，则that无法省略；若that引导的主语从句位于句末，而在句首使用了形式主语it，则that则可以省略：例如：thatyoudidn'tgotothetalkwasapity.很惋惜你没回去听到报告。

【英语知识点】名词性从句语法总结归纳名词性从句是在句子中起名词作用的句子。
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。
接下来分享名词性从句的语法，供参考。
1.主语从句通常由下列词引导：①从属连词that、whether等。
②连接代词what、who、which、whatever、whoever、whom、whichever等。
③连接副词how、when、where、why等。
that在句中无词义，只起连接作用;连接代词和连接副词都在句中既保留自己的疑问含义、又起连接作用，连接代词主要作主语，宾语，表语，定语等，连接副词在从句中作状语。
注：whom、who指人，what指物，whatever、whoever表示泛指意义。
2.有时为避免句子头重脚轻，常用形式主语it代替主语从句作形式主语放于句首，而把主语从句置于句末。
主语从句后的谓语动词一般用单数形式。
常用句型如下：(1)It be+名词+that从句：It's a great pity that they didn't getmarried.他们没能结婚，真是令人惋惜。
(2)It be+形容词+that从句：It's splendid that you passed yourexam.你通过考试了，真棒。
(3)It be+动词的过去分词+主语从句：It's said that he has been there many times.据说他去过那儿很多次。
(4)It+不及物动词+that 从句：It is suggested (requested, proposed, desired, etc.) that…。

在主从复合句中充当宾语，位于及物动词、介词或复合谓语之后的从句称为宾语从句。
宾语从句分为三类：动词的宾语从句，介词的宾语从句和形容词的宾语从句。
2.宾语从句的引导词有三种：(1)以that引导的宾语从句：that引导的宾语从句一般都是由陈述句充当，引导词that没有实际意义，不在从句中作任何成分，that可以省略，而且从句成分齐全，句意完整。

►从句的辨认如果想辨认从句类型，学生们应该对从句的基本形式有所认识。
无论是哪种从句类型，在句子中充当成分的"句子"应该都具备以下特征：从句=从属连词+句子了解了从句的基本结构，那么应该如何辨别从句类型呢?学生可以在句子中通过简单的公式进行辨认。
常见的从句出现形式有四类：1. 名词+从属连词+句子=定语从句/同位语从句2. 动词+从属连词+句子=宾语从句/表语从句3. ×+从属连词+句子=状语从句4. 从属连词+句子+动词=主语从句对于以上四类从句出现形式有了一定的了解，那么今天就首先看看第一类从句出现形式的辨认方法和注意事项吧!1. 名词+从属连词+句子=定语从句/同位语从句例子1：Yet, being friendly is a virtue that many Americans value highly and expect from both neighbors and strangers.(1997年Text2)从句类型：定语从句辨别方式：a virtue(名词)+that(从属连词)+many Americans value highly and expect from both neighbors and strangers(句子)译文：然而，表示友好是一种美德，美国人高度重视这种美德，并期望邻居和陌生人都能有这种美德。
高中英语语法（2）主语从句★背诵要点：1、主语从句是指主语用一个从句来表达的句子，也就是说在谓语动词前面的部分是一个从句的句子是主语从句。
2、主语从句的引导词有：1）连词：that, whether2）连接代词：who, what, which, whose, whom3）连接副词：where, when, how, why3、主语从句使用正常主谓语序，不能用倒装语序。
4、通常主语从句用形式主语it来代替，将从句置于句末。
5、that在主语从句中不能省略。
例如：What he said is hard to understand.Where he has gone is unknown to us all.That you find this exercise difficult is quite natural.It is quite natural that you find this exercise difficult.★注意要点：1、引导词that与whatwhat既有引导主语从句的作用,同时又在从句中作成分,这时what相当于all that或everything that...,常译成"所……的(东西、事情、话等.)";而that只起连接作用,本身无实际意义,在从句中也不担当任何成分.但that引导的主语从句放在句首时,不能省略that.例如:What is done can't be undone. (谚语) 已成定局, 无可挽回.2、引导词if和whether表示是否的意思时，不能用if代替whether.It hasn't been decided whether he'll come or not.Whether he'll come or not hasn't been decided.3、熟记以下变化Whoever=no matter who=any one whoWhichever=no matter which=any one whichWhatever=no matter what=anything that★基础题练习：1．_______your father wants to know is________ getting on with your studies.A.
