一、定义
名词性从句就是把完整句子当作名词来使用，使之在主句中充当某种成分。
一般在句中作主语，宾语，表语或同位语。
二、常用引导词：
(1)连接代词：who(ever)，which(ever)，whom(ever)，whose，what(ever)
(充当成分：作主语，宾语，表语等名词性成分)
(2)连接副词：
①表疑问：why，where(ever)，when(ever)， how(ever)， whether，if
② 表陈述：that
（连接作用，不作主干成分：做状语)
三、分类：
（1） 主语从句
What I feel like doing most now is going out for a drive.
Whether he'll take the job is still unknown.
Where they'll move their office to is not clear.
When he'll leave for New York hasn't been decided.
（2） 宾语从句
I hope that people will spend more money on education.
Do you know which football team Bill supports
Would you mind telling me what shoe size you take
I wonder whether I should accept the offer or not.
He asked if I could show him how to operate the air conditioner.
（3） 表语从句
His suggestion is that we should hire more experienced people.
That’s what we should do.
That is how they succeeded.
That is why he was late for school.
That was when my mum was in hospital.
（4）同位语从句
定义：是用于解释、说明某一名词的内容和实质的从句。在句中的作用等同于其前面的名词。
满足条件：
① 常用于抽象名词（含某种信息）前，如：fact , news , idea, hope, question, problem, advice, doubt, thought, evidence, suggestion…
② 从句不缺成分（常用 that 引导）
Note: if 不能引导同位语从句
判断方法（区分定语从句&同位语从句）：
凡是同位语从句，改为 The fact /news/ idea is/was… 结构时，语法、语意正确，而定语从句不可。
（4）同位语从句
The fact that she hadn’t said anything surprised us.
The news that our team won the game excited us all.
We are looking into the question whether he is worth trusting.
I have no idea why he was late.
（5）it 作形式主语的主语从句
当主语从句太长时，为了避免头重脚轻，保持句子平衡，常用it作形式主语，主语从句放在句末。
It's obvious that he enjoys his family life very much.
It's a shame that he doesn't respect his parents.
It matters greatly whether our parents understand and support you.
四、特殊情况：
（1）that 引导宾语从句可省略。
I expect (that) your team will win.
（2）介词后不跟that、if 引导的从句，只能跟“wh-”类连接词引导的宾语从句。
Kate was interested in what she had seen at the exhibition.
（3）表“是否”含义时，优选 whether
① 与 or not 连用 ② 介词之后 ③ 引导主语从句位于句首
1. they are looking for is their missing dog.
2. He said he had already known the news.
3. This school is my mother worked forty years ago.
4. There is no doubt human activity has caused global warming.
