1)名词在句子中的功能
主语表语宾语同位语
名词性从句在复合句中的功能相当于名词,因此相对应有:
主语从句表语从句宾语从句同位语从句
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.

宾语从句
1. I think (that) you will like the pictures.
2. My aunt said (that) she e and that she would also bring her daughter.
3. I asked the teacher whether / if we were going to the zoo tomorrow.
4. They are worrying about whether they can get there in time.
5. He has e what he wanted to be 10 years ago.
6. I don’t know why Jane was late for school this morning.
2. 引导名词性从句的连接词可分为三类:
1) 连接词 that, whether, if 
(不充当从句的任何成分)
2)连接代词: what, whatever, who, whoever, whom, whose, which.
3)连接副词: when, where, how, why
名词性从句的引导词:
:that (宾语从句可省略)
:if/whether
(表语从句只能用whether)
:wh-
语序:引导词+ 陈述句语气
(1) 由that 引导的宾语从句(that通常可以省略), 若含有两个相并列的宾语从句时, 只有第一个连词that可以省略
1. I heard (that) he joined the army.
2. She said (that) she e and that she would take care of my dog.
注意:
(2) 由whether / if 引导的宾语从句,
I wonder whether/ if you can change this note for me.
I am worrying about whether he e.
I am considering whether or not he will be fit for the job.
只用whether的情况:
b 介词后面
c whether or not (与or not 连用)
(3) 由疑问词引导的宾语从句 用who, what, when, where, how, whenever等关联词引导时,连接词在从句中担当一定成分,从句语序要用陈述语序
She doesn’t care about when he will finish the job.
I want to find out who knows the truth.
