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。

名词性从句解题三部曲
•着眼点在于表现为有时态形式的动词(动词时态) 1.根据有时态动词来确定主句。查看主句是否缺少 本该由名词充当的成分。*** 2.如果本该由名词充当的成分,却由一个句子来 代替(其中一定有一个表现为时态形式的动词), 把它定为名词性从句。然后根据主句所缺名词性 成分,明确其为何种类型名词性从句。*** 3.最后根据该类型从句本身所缺成分,确定适当 连结代词(副词),并放在从句句首。***

名词性从句的心病:最怕有人传闲话
the news that the People believe ___________________ economic crisis will be over soon. _______________________________.
区别在于主句是否缺成分:不缺--定从;缺---名从 联系在于某种等式关系:名词(代词)+定从=名从
定语从句与同位语从句的区别在于:
• He has just got the news that you told me yesterday. • He has broken the promise that he made last month. • 限定具体哪一个 •He got the news that the Chinese team had won the match. •He broke the promise that he would invite me to dinner tonight. •解释什么内容
That ___ our class team will win the school ___________ ____________________ basketball match It is very likely __________
