高中语法之-名词性从句 S

名词性从句专题讲解一、复习句子成分二、句子种类简单句、并列句、复合句(三大从句)一、名词性从句:在句子中起名词作用的句子叫名词性从句(Noun Clauses)。
1)名词性从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语。
2)因此根据它在句中不同的语法功能,名词性从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。
主语从句What he wants to tell us is not clear.宾语从句He has told me that he will go to Shanghai tomorrow.名词性从句表语从句The fact is that we have lost the game.同位语从句I have no idea when he will come back home.1. 这里重点强调一下同位语从句,顾名思义,所谓同位语从句就是一个句子与主句中某一个名词互为同位语!那么什么是同位语呢,很简单就是相同地位,相同成分,平起平坐,A(名词)=B(从句), B(从句)=A(名词), 去掉任何一部分(A/B)对整个句子都不影响。
2. 而且与从句互为同位语的名词一般为抽象名词,例如:advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。
二、引导名词性从句的连接词1.引导名词性从句的连接词可分为三类:1.连词:that(无任何词意)whether, if(均表示“是否”)as if ,as though(均表示“好像”,“似乎”)以上在从句中均不充当任何成分2. 连接代词:what, whatever, who, whoever, whom, whose, whichever, whomever3. 连接副词:when, where, how, why, how many, how much, how often2. 连接词的判定:根据连接词在从句中所做的不同的成分,我们可以归纳如下:人物主语:who what宾语:whom what名词性从句表语:whom what定语:which what whose状语:when where why how (how many, how much, how often)不做成份:that if/whether as if /as though互动精讲【知识梳理1】宾语从句(一)宾语从句简介用作宾语的从句叫做宾语从句。
