名词从句
从句具有以下几个特点
- 本身是一个完整的、独立的简单句
2.that 没有任何意义，语法功能表示后面跟着一个名词从句
3.名词从句需放在主要从句的名词位置，当做名词使用
（名词位置：主语、宾语、补语、同位语等位置）
简单示例
I know something
I am right
I know something that i am right
主语位置
Something is strange
He didn't show up on time
(A) That he didn't show up on time is strange
(B) It is strange that he didn't show up on time
宾语位置
The defendant said something
He didn't do it
(A) The defendant said that he didn't do it
(B) That he didn't show up is strange
(误) He didn't show up is strange
I(S) find(V) something(O) strange(C)
He didn't show up on time
(A) I find it strange that he didn't show up on time
这里有strange作为补语，用虚拟字it 暂代宾语位置。
介系词后面的冰雨，不能直接方名词从句作为宾语
补语位置
The car is ruined. The important thing is that we're all right.
The important thing is we're all right.
同位语位置
同位语其实就是形容词从句简化后之后留下的补语
The story that he once killed a man might just be true
I'm afraid that I can't help you
afraid后面并没有名词的位置
I'm afraid of that thing
I can't help you
You'd better take care of that thing
Nothing goes wrong
(A) You'd better take care that nothing goes wrong
