人教新课标选修八Unit1语法专题讲解-名词性从句名词性从句在句子中起名词作用的句子叫名词性从句。

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,名词从句又可分为主语从句、宾语从句、表语从句和同位语从句。

主语从句的用法一. 主语从句在复合句中作主语, 它可以位于句首, 但常见的主语从句多放在句末,句首则用形式主语it。

1.That the earth is round is true.= It is true that the earth is round.2. Whether he will come hasn’t been decided.= It hasn’t been decided whether he will come.注意: 连词that, whether在从句中不担任句子成分,只起连接作用,不能省略(注:if不可用来引导主语从句）二. 用it 作形式主语的结构(1) It is＋名词＋从句It is a fact that … 事实是…It is an honor t hat …非常荣幸It is common knowledge that…是常识(2) It is＋形容词＋从句(多用should)It is natural that… 很自然…It is strange that… 奇怪的是…(3) It is ＋不及物动词＋从句It seems that… 似乎…It happened that… 碰巧…It appears that… 似乎…(4) It is ＋过去分词＋从句It is reported that… 据报道…It has been proved that… 已证实…It is said that… 据说…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, 主语从句的连接词有变化。

第一单元语法第一单元—名词性从句1.含义：在句子中起名词作用的从句称为名词性从句2.类型：主语从句，宾语从句，表语从句和同位语从句。

3.连接词：that whether if4.疑问代词：who whom whose which what whoever whomever whicheverwhatever5.疑问副词：when where why how6.主语从句：主语从句可以放在句首，也可以it做形式主语，而从句放在句末What is I want to know is the news注意：a. that 引导主语从句大多数要放在句末。

b. what 引导的主语从句一般不用it 作形式主语It is a new bike what he wants.c.由whether及其他连词引导的主语从句放在句首或句末均可。

d.如果含有主语从句是疑问式，则需用it作形式主语。

Has it announced when the planes are to take off？7.常见的用it作形式主语结构a .It is +名词+that 从句It is a fact /a shame/a pity/ no wander/good news…that…b. It is +形容词+that从句It is important/wonderful/necessary/strange/possible/likely/..that..c. it is +过去分词+that 从句it is said/reported/decided/believed ..that...it is believed that computers have changed our daily life.d. it +不及物动词+that 从句it seems/turned out/does not matter.. that ..it turned out that he lied to us.8.主语从句作主语，谓语一般用单数。

第2讲A land of diversity 语法篇____________________________________________________________________________________________________________________________________________________________________1.掌握名词性从句的结构与功能；2.能够熟练选用合适的引导词。

一. 概述：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。

二. 分类（一）主语从句主语从句是在复合句中充当主语的从句，通常放在主句谓语动词之前或由形式主语it代替，而本身放在句子末尾。

引导主语从句的连词有：that, whether, who, whom, what, whatever, whose1.常规主语从句，既复合句在句中充当一个主语，那么这个句子就是主语从句(1)That he finished writing the composition in such a short time surprised us all.(2)Whether we will go for an outing tomorrow remains unknown.(3)Who will be our monitor hasn’t been decided yet.(4)Whom we must study for is a question of great importance.(5)What caused the accident remains is unknown.(6)What we need is time.注：连词位于句首不能省略2. It 作形式主语和it引导强调句的比较（为了防止句子头重脚轻，通常把形式主语it放在主语位置，真正主语搁置于句末）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。
