名词性从句
名 词 性 从 句
名词性从句名词性从句包括：主语从句、表语从句、宾语从句和同位语从句。
引导名词性从句的连词有：A.连词：that, whether, if（这三个词都不作从句的成分，同时，that无含义，而whether 和if都表“是否”）B.疑问代词：who, whom, whose, what, whichC.疑问副词：when, where, why, how（一）主语从句在复合句中充当主语的从句。
1.that引导主语从句that引导主语从句时不同于其他的连词，既无词义也不作成分，只起单纯的连接作用，且通常不可以省。
为了强调that引导的主语从句而置之于句首时，that不可省。
①That the driver could not control his car was obvious.②That she was chosen made us very happy.③That he will come is certain.④That he would take the risk is true.⑤That he should have married her isn't surprising.★通常，that引导主语从句时用it做形式主语，把从句置于句尾，此时that有时可省。
例如：①It was obvious that the driver could not control his car.②It made us very happy that she was chosen.③It is certain that he will come.④It is true that he would take the risk.⑤It isn't surprising (that) he should have married her.★如果以that从句为主语的句子是疑问句，就只能用先行词it结构。
