NounClauses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，名词性从句可分为主语从句、表语从句、宾语从句和同位语从句。
1、宾语从句
宾语从句在复合句中起宾语作用，可以作动词的宾语，也可以作介词的宾语。引导宾语从句词有连词that，if，whether；连接代词who，whose，what，which；连接副词when，where，how，why等。总结:e.g.Tomisnolongerwhatheusedtobe.
Thequestioniswhichofusshouldcomefirst.
Theproblemiswhoisreallyfitforthehardjob.
Theimportantthingiswhosenameshouldbeputonthetopofthelist.2.注意点Thereasonwhyhewaslatethismorning

做主语用的名词性从句，因其在复合句中做主语，又称主语从句，引导主语从句的有连词that，whether，连接代词who，what，which，连接副词when，where，how，why等。

2.总结:3).whether可以引导主语从句解释为”是否”,但if不能.4、同位语从句
同位语从句属于名词性从句，大多由从属连词that引导，常常跟在fact,news,idea,thought,question,reply,report,remark,hope,belief等名词后面。同位语从句一般用来解释或说明这些名词的具体含义或内容，在逻辑上表现为同为关系。

注意
1.that引导的同位语从句前面的名词常见的有:idea,fact,news,belief,thought,doubt,suggestion,proof,message,order,conclusion,desire,theory,truth,word,hope,information等.
