#同位语从句
引入:插入语(起补充说明作用,没有主句重要)
1. 逗号相隔(句子头尾都有逗号)
2.连字符相隔(句子头尾都有连字符)
三个特点:逗号/连字符、词性不固定、不影响句子完整性
同位语
一个名词对另一个名词进行修饰,第二个名次就是同位语
a.有逗号相隔
Exa. :James Boswell, his biographer, described the garret as 'fitted up like a counting house'.
b.没有逗号相隔
Exa. :Energy and other resources have become more abundant, since the book The Limits to Growth was published in 1972.
三个特点:逗号/无逗号、名词、放在名词后
公式一:that +陈述句=同位语
#同位语从句与定语从句
I heard the news that they won the game. 同位语从句
I heard the news that happened yesterday. 定语从句

不同:同位语在抽象名词后面;同位语不是完整的句子

主语从句:A is a fact.
宾语从句:Tom says A.

#It 在阅读中的用法
用法一:指代名次
用法二:形式主语(三个公式)
用法三:强调句
公式一:It is +被强调部分+that
被强调部分在从句中为a.主语 b.宾语c.状语
a.被强调部分为主语
It was Tom that saved the girl from the river last night.
b.被强调部分为宾语
It is Kate that the monitor likes.
c.被强调部分为状语
It is at 6 am that I should arrive at the workplace.
It will be in the room that the meeting will be held.
被强调部分为状语时,句子是完整的,主语和宾语不完整
