主语从句、宾语从句、表语从句、同位语从句,定语从句和状语
从句
二、名词性从句的连接词
1. 单纯连词

Eg : That the prices of rice will go up is certain. (that引
导主语从句,补充当任何成分)

形式主语it 代替主语从句位于句首时,常见的几种情况:
① It + adj +that 从句(大多数情况下that从句后用should+动词原形)
Adj: necessary right clear unlikely strange obvious natural important
Eg: It is necessary to learn English well.
② It +系动词+名词+that 从句
Non: a pity an honor good news a wonder a fact no wonder no surpeise
Eg: It is a fact that you are a good boy.
③ It +be + 过去分词+that从句
过去分词:said / heard/ reported/ told/
decided/suggested/thought/considered/ hoped/ announced
Eg: It is announced that the plan has been canceled.
注意:
It + be+ suggested/ advised/ ordered/ requested/ insisted/ demand+ that从句, that从句要用should +动词原形,should可以省略。
Eg: It is suggested that you (should ) spend more time in studying English .
当suggest表示“表明”时,不可以用虚拟语气
Eg: It suggests that you are an honest boy.
Insist 表示“坚持某种说法(事情已经发生过了)”,不用虚拟语气。

Eg: she insisted that I have never done such thing .
She insisted that I study abroad.
