定语从句、状语从句和名词性从句精讲(上)
高考英语三大从句(名词性从句、定语从句、状语从句)讲解+练习(附答案)
高考英语三大从句讲解+练习（附答案）【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，名词性从句成分为主语从句、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。
1. 主语从句作句子主语的从句叫主语从句。
主语从句通常由从属连词that，whether，if和连接代词what，who，which，whatever，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；连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。
例如：What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。
It is known to us how he became a writer. 我们都知道他是如何成为一名作家的。
Where the English evening will be held has not yet been announced.英语晚会将在哪里举行，还没有宣布。
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（2）It + be + 形容词+ that从句（3）It + be + 动词的过去分词+ that从句（4）It + 不及物动词+ that 从句另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时，谓语动词要用虚拟语气“(should) +do”，常用的句型有：It is necessary (important, natural, strange, etc.) that …It is a pity (a shame, no wonder, etc.) that…It is suggested (requested, proposed, desired, etc.) that…注意：连词that, whether在从句中不担任句子成分，只起连接作用，不能省略。
云南省普高专升本公共课(公共英语)语法精讲(六)：名词性从句、定语从句与状语从句
云南普通专升本公共课（公共英语）语法精讲（六）：名词性从句、定语从句与状语从句学习目的：1. 掌握四大名词性从句，特别是引导词的选择。
2. 掌握限定性定语从句和非限定性定语从句。
3. 掌握常见的状语从句及其引导词的选用。
在主从复合句中，根据其语法作用可以分为：名词性从句、定语从句和状语从句。
引导从句的关联词有三种，分别为：1. 连词that, whether, whether…or(not), if. 连词只起到连接作用，在从句中不充当任何成分。
不可以省略。
2. 连接代词who, whom, whose, which, what, whatever, whoever等。
它们既起到连接作用，又在从句中起到代词的作用。
3. 连接副词when, where, why, how. 它们既起连接作用，同时也在从句中作状语。
一．名词性从句在句子中起名词作用的各种从句，统称为名词性从句。
它具体又包括：主语从句、表语从句、宾语从句和同位语从句。
1．主语从句整个句子做主语，放在主语的位置就叫主语从句。
引导词有that, whether, what, how等如：That he will come to the discussion is certain.That mathematics is one of the most useful and fascinating divisions1in human knowledge is widely accepted.Whether it will do us harm or good remains to be seen.How he managed to accomplish the job is of interest to us all.Where we shall do the test is still under discussion.Why the sun in the morning looks bigger than the sun at noon is very interesting.主语从句放在句首，句子常常显得比较笨重，因此常把它移到句子末尾，用it作形式主语。
语法讲座之九名词性从句和定语从句和状语从句
语法讲座之九：名词性从句和定语从句和状语从句一、名词性从句名词性从句指主语从句、宾语从句、表语从句和同位语从句。
（一）主语从句1．主语从句的引导词：wh- / that 。
例如：That he will accept the offer seems unlikely.That he always studies hard is known to us.What they are after is profit.Who will go with you hasn’t been decided yet.2. 如果主语太长或为了保持句子的平行，绝大部分主语从句用it作形式主语，将真正的主语从句放在后面。
例如：①It is + 形容词+that②It is + 名词+that③It is + 动词+thatIt is likely that it is going to rain. ①It is no use that you go there in person. ②It is known that football is played all over the world. ③(二) 宾语从句宾语从句的引导词：wh- / that 。
例如：We must find out who did all this.He told me (that) he could do it for me.He has made it clear that the meeting will not be postponed.注意：if 和whether在引导宾语从句时的特殊用法①whether or not / whether…or not 连用是固定搭配，这时，whether 不能用if来替换。
②如果宾语从句是否定句时，只能用if而不能用whether来引导。
例如：I don’t care if it doesn’t rain.I don’t care if the factory doesn’t have my pay raised.(三) 表语从句表语从句的引导词：wh- / that 。

高中英语-定语从句、状语从句和同位语从句 知识点总结
高中英语-定语从句、状语从句和同位语从句知识点总结复合句【语法要点】复合句是由一个主句加一个或几个从句所构成的句子。
从句只用作句子的一个成分，不能独立。
根据从句在句子中的作用，可分为名词性从句、定语从句和状语从句三类。
（一）名词性从句名词性从句包括主语从句、表语从句、宾语从句、同位语从句。
其关联词有连接词that、if、whether；疑问代词who、what、which和疑问副词when、where、how、why等。
1.名词性从句句法结构：从属连词that whether 主语从句That he will come is certain.（that不可省）Whether she is coming or not doesn’t matter too much.（不能用if）宾语从句I think（that）he will be all right in a few days.I went in and asked if（=whether）they had a cheap suit.I wonder whether（不能用if）it is true or not.表语从句The fact is（that）I have never been there.The question is whether（不能用if）it is worth doing.同位语从句The fact that she had not said anything surprised all of us.They asked me the question whether the work was worth doing.连接代词that who whom whose 主语从句Who will help him is not known.What he said is very important.Which side will win is not clear.宾语从句（1）作及物动词的宾语。
名词性从句 定语从句 状语从句
1．名词性从句定语从句状语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、从属连接词：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（从属连词）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 kept the door open all night was unkonwn.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. It made us surprised that he…（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。
