高考名词性从句最全面的讲解与专练 (1)
高考名词性从句定义：在复合句中起名词作用的从句叫做名词性从句。
它包括主语从句、宾语从句、表语从句和同位语从句。
名词性从句的功能相当于名词词组, 它在复合句中担任主语、宾语、表语、同位语、介词宾语等。
高考对于名词性从句考查主要有以下七个方面：1.名词性从句的语序问题2. 引导词that与what的区别3. it在名词性从句中作形式主语或形式宾语的用法4. whether与if的区别5. 名词性从句中的疑问词+ever引导的名词性从句与no matter+疑问词引导的状语从句的区别6. 名词性从句中的虚拟语气问题7.易混句型的辨析，比如it作形式主语，主语从句后置的句型与强调句型，与定语从句、状语从句的辨析等。
语法要点一、名词性从句的连接词引导名词性从句的连接词可分为三类：连接词：that, whether, if, as if；that 无词义，在从句中不担任成分，只起连接作用，有时可省略。
if (whether), as if虽有词义，但在从句中不担任成分；连接代词：what, whatever, who, whoever, whom, whose, which，whichever. 连接副词：when, where, how, why有词义，在从句中担任成分，作状语；连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。
不可省略的连词：1. 介词后的连词I can judge by what (=the things that)I know of him.She walked up to where he stood.2. 引导主语从句和同位语从句的连词。
That she was chosen made us very happy.We heard the news that our team had won.比较： Whether与if 均为"是否"的意思。

3. 连接副词：when(＝the time when什么时候，何时)，where(＝the place where什么地方，何地)，how(＝the way that/in which怎样， 以……方式，如何)，why＝the reason why为什么)。它们除起连 接作用，还在从句中作状语。
3) wh类连接词引导的主语从句： wh类连接词包括wh类的连接代词(who, whom,
whose, which, what, whoever, whomever, whichever, whatever等)和连接副词(when,
where, how, why, whenever, wherever, however 等)。what, when和wh-ever类的词有时可不表 疑问。wh类连接代词在句中既起连接作用， 又可充当主语、宾语、表语、定语等成分。 wh类连接副词在句中起连接作用，在从句中 可充当时间、地点、原因、方式状语。
【温馨提示】 ①whether/ if引导宾语从句表示“是否”
的意思时，一般情况下可互换。 ②if引导宾语从句时可以有否定式，而
whether从句则没有。 e.g. I don’t care if he doesn’t come.
5) 特殊疑问词引导的宾语从句： 由who, what, how, which, whose, where, why等词引导的宾语从句，可作动词、 介词及形容词的宾语。
【温馨提示】 doubt, doubtful与sure后名词性从句连接词 that, whether, if的选择。 ①当doubt, doubtful用于肯定句时，后面的名
词性从句的连接词常用whether或if；当 doubt, doubtful用于否定句或疑问句时，后 面名词性从句的连接词用that。
