1. 概念
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,名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。其功能同名词一样。
名词性从句
Who will win the match is still unknown.
I want to know what he has told you.
The fact is that we have lost the game.
The news that we won the game is exciting.
主语从句
宾语从句
表语从句
同位语从句
2. 引导名词性从句的连接词可分为三类:
连接词/从属连词that, whether, if 不充当从句的任何成分
连接代词: what, whatever, who, whoever, whom, whose, which.
连接副词: when, where, how, why
3. 不可省略的连词：
1) 介词后的连词
2) 引导主语从句和同位语从句的连词不可省略。
That she was chosen made us very happy.
We heard the news that our team had won.
4. whether与if 均为“是否”的意思但在下
列情况下, whether 不能被if 取代
1) whether引导主语从句并在句首 Whether it is going to rain is still unknown.
2) 引导表语从句 The question is whether he is going to come.
3) whether从句作介词宾语
4) 从句后有“or not”
That the earth is round is true.
= It is true that the earth is round.
一、主语从句的用法
(一). 主语从句在句中作主语, 主语从句可以位于句首, 但常见的主语从句多放在句末, 句首则用形式主语it。
What we need is some interesting news.
2. What people want are pictures on the page.
3. What the teacher told me is the truth.
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）
