2021届高中英语新高考语法核心考点专项复习（07）名词性从句知识点整理总结

2021届高中英语新高考语法核心考点专项复习（07）名词性从句知识点整理总结   概述：　名词性从句的功能相当于名词。根据其在句中充当的成分，可分为：主语从句、宾语从句、表语从句和同位语从句。 主语从句   在复合句中做主语的从句叫主语从句。引导主语从句的连词：that（无意义，所引导的主语从句是完整的），whether （是否），if （是否）（通常只能用于it作形式主语的主语从句），连结代词： who （谁）（主格）, whom （谁）（宾格）, whose（谁的）（所有格）, what （什么，所……的（东西或事情））, which （那个，那些），whoever （无论谁）（主格）, whomever （无论谁）（宾格）, whatever（无论什么）, whichever （无论那个，无论那些），连接副词： when（何时）, where （何地）, how （怎样，如何）, why （为什么）等。如： That the 2022 Winter Olympic Games will be held in Chengde is known to us all.  =It is known to us all that the 2022 Winter Olympic Games will be held in Chengde. =What is known to us all is that the 2022 Winter Olympic Games will be held in Chengde. =As is known to us all, the 2022 Winter Olympic Games will be held in Chengde. 众所周知，２０22年冬季奥运会将在承德举行。 That you don’t like him is none of my business.   你不喜欢他与我有什么关系呢。 What he said at the meeting astonished everybody present. 他在会上的发言是到会的人都感到惊讶。 What are to be decided at the meeting will be announced tomorrow. 在会议上即将做出的决定明天就会公布。 What is known to us all is that China is a developing country. = that China is a developing country is known to us all. ＝It is known to us all that China is a developing country. =As is known to us all, China is a developing country. 众所周知，中国是一个发展中国家。   注：　由于主语从句一般都较长，所以常用it作形式主语，而把主语从句置于句末。如：　 It worried her a bit that her hair was turning gray.  =Her hair was turning gray, which worried her a bit. =Her hair was turning gray, and it worried her a bit. =Her hair was turning gray. It worried her a bit. 头发日渐灰白使他有些担忧。 It is a fact that Chinese is being accepted as an international language. 汉语正逐渐被人们承认为一门国际语言是一个事实。 It happened that she married a man whose father had killed her father. 碰巧她嫁给了一个他的父亲杀害她的父亲的男人。   宾语从句   在句中做宾语的从句叫宾语从句。宾语从句可以作谓语动词、介词、非谓语动词和一些形容词的宾语。引导宾语从句的连词：that（无意义，所引导的主语从句是完整的），whether （是否）， if （是否）（通常只能用于宾语从句，但不能与or not连用）, 连结代词： who （谁）（主格）, whom （谁）（宾格）, whose （谁的）（所有格）, what （什么，所……的（东西或事情））, which （那个，那些），whoever （无论谁）（主格）, whomever （无论谁）（宾格）, whatever（无论什么）, whichever （无论那个，无
