定义：在句子中起名字作用的句子，在句子中可以充当主语、表语、宾语、同位语成分。 分类
主语从句表语从句 宾语从句 同位语从句
His wrds made me angry. （主语） What he said made me angry. （主语从句） This is the truth. (表语) This is what he tells me.（表语从句） He tells me his plan.(间接宾语 直接宾语) He tells me that he will leave fr Beijing next Mnday.(间接宾语 宾语从句）Lily,my friend,is a very famus singer.(同位语)The news that we wn the game is exciting.(同位语从句)
1.that，whether，if：在从句中不充当主成分。that 连接陈述句，本身无意义；whether、if 连接一般疑问句，意思为“是否”。 例 That he surrived the earthquake is a miracle. We dn’t knw if/weather he will believe us .一般而言，whether和if 在引导宾语从句时，可以互换。但以下情况只能用whether：whether和if都可以引导主语从句，但是，放在句首的主语从句只能用whether。 例 Whether she will cme n time is unknwn.
引导介词宾语从句时只能用whether。 例 I am curius as t whether she will cme n time. I am nt sure if/whether she will cme n time.引导表语从句只能用whether。 例 The questin is whether she will cme n time.引导同位语从句，只能用whether。 例 The prblem whether we shuld wait fr her has nt been slved.固定结构 nt. 例 I am nt sure whether she will cme n time r nt.固定结构：whether＋不定式，即 whether t d . 例 I dn’t knw whether t attend his wedding.
dubt 后接 that,whether/if 的句意区别：例 I dubt that he is guilty.我不信他有罪。 =I dn’t think he is guilty.I dubt whether/if he is guilty.我不知道他是否有罪。 =I am nt sure whether he is guilty r nt.I dn’t dubt that he is guilty. 我相信他是有罪的。 =I believe that he is guilty.I suspect that he is guilty. 我怀疑他有罪。 =I think that he is guilty.
2.连接代词wh，whm，whse， what， which， whatever，whichever，whever在名词性从句中充当主语、宾语、表语、定语等成分。例 Have yu decided which bk t read first.(which 引导宾语从句，同时在从句中充当bk的定语。) Wh will be invited has nt been decided.(wh 引导主语从句，同时在从句中充当主语。)what引导的名词性从句根据不同含义分为两种类型：疑问代词型名词从句、连接性代词型名词从句。疑问代词型名词从句 what意为“什么”、“哪些”、“怎样”等疑问语意的词，可以充当主语、宾语、表语、插入语等。
例 I have nt made up my mind what ptinal curses I will take next rerm.（作定语） 我还没决定下学期上哪些选修课。 He desn’t mind what peple think f him.(作宾补) 他不在意人们怎么看他。 What made him cnfused is what happened in the accident.(作主语) 令他困惑的是在那场事故中发生了什么。连接代词型名词性从句中，what相当于一个名词加一个定语从句，意为“所的东西”，在句子中作主语、宾语、表语、插入语等。 What is trubling me is that I dn’t have experience in this kind f wrk.（作主语） 使我感到麻烦的是，我没有多少这种工作的经验。
Air is t us what water is t fish.(作表语) 空气对于我们犹如水对于鱼。I will give yu what help I have. (作宾语) 我会尽我所能给你帮助。What has made China what she used t be twenty years ag.(作宾补) 是什么使中国二十年前成为那个样子。
3.连接副词when,where,hw,why,在名词性从句中充当状语成分。例 We did nt knw why the meeting was pstpned. (why 引导宾语从句，why在从句中充当原因状语。)Can yu find ut hw t slve the prblems?(hw 引导介词宾语从句，hw在从句中充当方式状语。)I dn’t knw where I can find them.(where 引导宾语从句，where在从句中充当地点状语。)
4.wh/what/which/when/where/hw-ever的用法，表示不确定的泛指“任何、无论”。whever=n matter wh （anyne wh）无论谁 （任何人）whatever=n matter what (anything that) 无论什么 （任何事）whichever=n matter which (anything which) 无论哪一个 （任何一个）whenever=n matter when (anytime when) 无论什么时候wherever=n matter where (any place where) 无论哪里 无论什么地方hwever=n matter hw (any way in which) 无论如何 无论怎样例 Wh will be the new manager has nt been decided. This psitin will be given t whever is capable fr the jb.=This psitin will be given t anyne wh is capable fr the jb.
定义：主语从句是在复合句中做主语的从句。位置：一般出现在句首，谓语动词之前。多数情况下，为平衡句子结构，常用it代替主语从句，将主语从句后置，it充当形式主语。例When he will be back is still unknw.Whever cmes is welcme.What makes me angry is his attitude.Hw this happened is nt yet clearIt is nt imprtant wh will g.注意：由what，whatever，whever等引导的主语从句一般不能用it作形式主语。
表语从句在句中充当表语，位于主句系动词之后。 The questin is wh can cmplete the difficult task.表语从句可用whether引导，也可用as if/thugh 引导，但不用if引导。His first questin was whether Tm had arrivrd yet.He lked as if he wanted t remember all the things in the rm.当主句主语是reasn时，表语从句的连接词用that而不用because。区分：That’s +结果That’s +原因The reasn that...
