高中英语名词性从句精讲从句是相对于主句而言的,即它是从属于某一个主句,而不能单独作一个句子。
在英语中,主要有三大从句,即名词性从句(包括主语从句,宾语从句,表语从句,同位语从句)、形容词性从句(即定语从句)、副词性从句(即状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等)。
在句子中起名词作用的句子叫名词从句(Noun Clauses)。
名词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、同位语等,因此根据它在句中不同的语法功能,名词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。
引导名词性从句的连接词可分为三类:(1)从属连接:that, whether, if(不充当从句的任何成分)(2)连接代词:what, whatever, who, whoever, whom, whose, which.(3)连接副词:when, where, how, why名词性从句知识点汇总1名词性从句的分类名词性从句,包括四种从句,即主语从句、宾语从句、表语从句、同位语从句。
因为主语、宾语、表语、同位语这四种成分均可以由名词构成,所以这四种从句在主句中都充当了名词的作用,故将这四种从句统称为名词性从句。
如:1.That she will help me made us happy.(主语从句)2.I can understand what he said.(宾语从句)3.This is where I was born.(表语从句)4.The fact that a heavy earthquake happened made me crazy.(同位語从句)2名词性从句的连接词分类1.that(无含义,不充当成分)2.whether,if(有“是否”的含义,但不充当成分)3.连接代词:what, whatever, who, whoever, whom, whomever, whose, which, whichever.(在从句中做主语、宾语、表语和定语)连接副词:when, whenever, where, wherever, how, however, why (在从句中做状语)4. as if,as though,because(不充当成分,在名词性从句中只引导表语从句)3连接词 that 在名词性从句中可以省略的三种情况1.it 做形式主语,that引导主语从句时It is said (that) he has been studying abroad.据说他一直在国外学习。
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)。
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、介词宾语等,因此根据它在句中不同的语法功能,名词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。
第一节知识点讲解顾名思义,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。
如 :What I saw was beyond any verbal description.That his hair was turning grey worried him a bit.Why the company denied the contract is still unknown.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.It remains to be seen whether the new novel will be well received.Tips: 主语从句的 that 绝对不能省去。
因为句子是不能做主语的,故用 that 引导。
若去掉则没有了主语,而宾语从句的 that 可省。
主语从句: That he is right is known to all of us.宾语从句: We all know (that) he is right.1.It 作形式主语和 it 引导强调句的比较It 作形式主语代替主语从句,主要是为了平衡句子结构,主语从句的连接词没有变化。
而 it 引导的强调句则是对句子某一部分进行强调,无论强调的是什么成分,都可用连词that。

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。

2、宾语从句(1)常见的可以接that从句作宾语的动词有see, say, know, imagine, discover, believe, tell, show, think, consider, be sure, be afraid等。
