* 高三英语总复习基础部分——语法讲解篇 2.4　高中英语常用语法——名词性从句 一、基本知识与基本概念 什么是名词性从句? 请看下表: 根据从句在句子中的功能分 根据从句的性质分 定语从句 形容词性从句 主语从句 名词性从句 宾语从句 表语从句 同位语从句 状语从句 副词性从句 引导名词性从句的连接词 1.主语从句 主语从句在句子中作主语。有时本身出现在主语的位置上,也有时出于句子结构的考虑退到句子的尾部,前面用形式主语it代替。从句作主语时,谓语动词一般为单数形式。 连接词:that(不可省略),whether(不能用if),wh-疑问词 e.g.That his hair was turning grey worried him a bit.? { 连接词that,if,whether 连接代词who,whom,what,whose,which,whichever,whatever,whoever 连接副词when,where,how,why,wh-ever Whether the new novel will be well received remains to be seen.? When and where the government will build a city square is under discussion.? It is pretty annoying that a small part of the machine is missing.? 2.宾语从句 在句子中作宾语的从句就是宾语从句。宾语从句也有自己的特殊情况,如介词的宾语、形容词的宾语、宾语从句提前和并列的宾语从句等现象。? 连接词:that(可省略),whether(能用if,但后面有or not 则必须用whether),wh-疑问词 e.g.We assumed that there would be more than 100 guests.? That will depend on whether they can get the chance or not.? I am not sure at the moment if I will have the time.? He told the police in detail what he saw and heard.? 3.表语从句 表语从句应该出现在系动词的后面。? 连接词:that(最好不要省略),whether(不用if),as if,wh-疑问词 e.g.The only question left is how often the workers are paid.? His idea for the coming weekend is that we go skating.? 4.同位语从句 同位语从句主要出现在一个名词的后面,起着解释说明的作用。有点像定语从句。这个点是许多学生容易混淆的地方。但是,只要我们能把握住关键,即:定语从句的先行词在从句中必须作一个成分,也就是说,定语从句必须缺少成分。 而同位语从句前面的名词在从句中是不作成分的。况且,也不是所有的名词后面都会跟同位语从句,只有那些“有内容的名词”才需要解释。如fact,news,idea,truth,hope,problem,information,belief,thought,doubt等。 连接词:that,whether(不能用if),wh-疑问词 e.g.People ignored the fact that the policeman didn’t fire at the man at all. Do you have any idea what is going on in the classroom? The possibility that we can work at home makes everybody excited. 二、考点分类解析 考点一:语序问题 名词性从句的语序问题:陈述句语序。即名词性从句中不会出现助动词提前的现象。 e.g.Can you tell me what size shoes you wear? I don’t know what is wrong with him. 对比: Who he is doesn’t matter.(正) Who is he doesn’t matter.(误) I don’t know
