适用文档名词性从句解说在复合句中起名作用的从句叫做名性从句。
它包含主从句、从句、表从句和同位从句。
名性从句是中学段的一个重要法目，在年的高考取几乎都波及到，而且每年的命各有化。
解析届高考名性从句考的焦点主要有以下六个方面1.考名性从句的序2.考引 that与 what 的区3.考 it 在名性从句中作形式主或形式的用法4.考 whether 与 if 的区5.考名性从句中的疑+ever 引的名性从句与no matter+ 疑引的状从句的区6.考名性从句的虚气法重点解析一、名性从句主从句、表从句、从句、同位从句，在整个句子中所起的作用，相当于一个名。
所以，四种从句通称名性从句。
引名性从句的接可分三：接： that, whether, if（不充任从句的任何成分）接代： what, whatever, who, whoever, whom, whose, which.接副： when, where, how, why1.主从句作句子主的从句叫主从句。
主从句往常由附属that ，whether ，if和接代what ，who，which ，whatever ， whoever 以及接副 how， when， where， why 等引。
that 在句中无，只起接作用；接代和接副在句中既保存自己的疑含、又起接作用，在从句中充任从句的成分。
比如：What he wants to tell us is not clear.他要跟我什么，不清楚。
It is known to us how he became a writer.我都知道他是如何成一名作家的。
Where the English evening will be held has not yet been announced.英晚会将在哪里行，没有宣告。
有防止句子重脚，常用形式主it取代主从句作形式主放于句首，而把主从句置于句末。
主从句后的一般用数形式。
