18-19 Unit 1 Section Ⅲ Grammar——名词性从句(Ⅰ)
Ⅲ ——名词性从句(Ⅰ)[语 境 自 主 领 悟]名词性从句相当于名词，可分别作主句的主语、表语、宾语和同位语。
因此，名词性从句分为主语从句、表语从句、宾语从句和同位语从句，都不能用逗号与主句分开。
.(主语从句) 't a .(宾语从句) .(表语从句) I .(同位语从句) 一、引导名词性从句的连接词她感到自己的脸颊因为害羞而慢慢变红。
1．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代替，而本身放在句子末尾。
主语从句通常由连词和、连接代词或连接副词引导。
2．在句中无词义，只起连接作用，在口语和非正式文体中可以省略，但从句位于句首时，连词不能省略。
3．连接代词和连接副词在句中既保留自己的疑问含义又起连接作用，在从句中充当成分。
.足球赛将会推迟一事现在已经确定。
a .他是否会来仍然是个问题。
a .违反该法者应予以罚款。
.飞机何时起飞还没有宣布。
.众所周知，光沿直线传播。
[即时演练1]单句改错①.前加②→③.→三、表语从句1．表语从句是在复合句中作表语的名词性从句，放在系动词之后，一般结构是“主语＋系动词＋表语从句”。
可以接表语从句的系动词有，，等。
表语从句通常由连词，，连接代词和连接副词，以及，，等连词引导。
.这个女孩已经不是10年前的她了。
.看起来像是要下雨了。
.问题是我们是否应该接受他们的邀请。
.这就是我们推迟会议的原因。
2．当主语是时，表语从句一般要用引导而不用。
't .彼得还没有来的原因是他没赶上这班火车。
3．如果主句的主语是，，，，等表示“建议、命令、请求”的名词时，其后的表语从句要用虚拟语气，谓语形式是，可省略。
() a .我的建议是我们应该讨论一下这个问题。
[即时演练2]选词填空：，，，①.②'s 't .③.④ 6 o' .四、宾语从句1．宾语从句就是在复合句中作宾语的名词性从句，通常放在主句谓语动词(及物动词)或介词之后。
Unit 19 lesson 1 语法：名词性从句
3.whether和if都有“是否”的意思，一般情况下两者可以换用， 但在介词之后，不定式之前，与or not连用，在句首或在引导
表语从句，同位语从句时，只能用whether,
如：I want to know if/whether the news is true. He doesn't know whether to stay or not? 4.宾语从句要用陈述句语序。 5.宾语从句一定要注意时态呼应，即：当主句谓语动词是过去式 时，从句中谓语动词也要用过去范畴的时态，但若从句陈述的是 真理或客观规律，其谓语的时态仍用一般现在时，
3) It + be +过去分词+从句 It is said that... 据说…… It is known to all that...
众所周知……
It is reported that... 据报道…… It is believed that...
人们相信……
It is suggested that... 有人建议……
相信, 至少有二十座楼房遭到破坏或彻 底毁掉。
5) . 用于It is important / natural /
necessary / impossible that...句型中,
主语从句应使用虚拟语气, 谓语动词用
“should + 动词原形”的形式, should
有时有感情色彩。
主语从句与强调句的区别
what既有引导主语从句的作用,同时又在 从句中作句子成分(主语、宾语、表语等). 这时what相当于all that/everything that...,常译成"所……的(东西、事情、话 等.)"; that只起连接作用,本身无实际意义,在从 句中也不担当任何句子成分.但that引导的 主语从句放在句首时,不能省略that.例如:
高中必修三 unit 3 grammar 名词性从句
She said (that) she would never come back again.
注意：一般情况下只能接wh-类连接词引导的宾语 从句。少数几个介词如excerpt, but, in 后可接that 引导的宾语从句。
引导名词性从句的连接词可分为三类：
一、从属连词（5个）： that; whether, if ; （均表示“是否”表明从句内容的不确定性 as if ,as though . （均表示“好像”，“似乎”）
二，连接代词（9个）： what, whatever, who, whoever, whom, whomever, whose, which, whichever
（2）that没有任何实义，而what可翻译为 什么；
（3）what 任何时候不可省略，而that在引 导宾语从句时可以省略。
关联词的功能; a. 连词 b.充当成分 c.具有一定实义 那么，其中从属连词有_a___;
连接代词和连接副词有_____b_. c
宾语从句可分为三种类型：
1.由从属连词that引导的宾语从句表述陈述意思， 连词that通常可以省略。
三，连接副词（7个）： when, where, how, why, whenever, wherever, however
Group one
I don’t know what we will do next.
I don’t know where we will go this afternoon.
在句子中起名词作用的句子叫 名词性从句 (Nominal Clauses）。 名词性从句的功能相当于名词词 组，它在复合句中中能担任主语、 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.
