二、名词性从句的连接词
一般规律：
针对从句成分，如果作的是主语、宾语、表语的话，这个词就是连接代词；如果作的是各种状语，就叫连接副词；
如果不作任何成分，就叫从属连词。语序必须是陈述语序。如下表：
从属连词that, if, whether
引导名词性从句
的连接词连接代词who, whom, what, whose, which, whichever, whatever, whoever
连接副词when, where, how, why，as if, because
三、特别注意若干点
1）I asked her __________ she had a bike.
2）I don’t know ___________ he is well or not.
3）___________ we will hold a party in the open air tomorrow depends on the weather. 4）It hasn't been decided____________ we shall attend the meeting.
5）We’re worried about ________ he is safe.
6）The question is _________ he should do it.
7）The doctor can hardly answer the question__________ the old man will recover soon.
8）I don’t know _______ to go or to stay at home.
2. that和whether的区别:that无意义，whether有疑问意义
I don’t know ________ he can join us or not.
I’m sure_______ he can join us.
It is none of your business _________ I love her.
It is none of your business _________I don’t love her.
I doubt____________ he can speak English. I don’t doubt ____________ he can speak English.
3.that，what的区分
what不但起连接作用，而且有具体意义，意为“所……的”（the thing(s) that），在从句中作主语，表语或宾语。而that 在从句中无词义，只起连接作用。简言之，从句中如果不缺少成分时，连接词用that，否则用what。
1）_______ he needs is more practice.
2）_______ he got the first place in the competition surprised us.
3）The truth is ______ I didn’t go there
4）He is not _______ he used to be 20 years.
5）_______impressed me most was ______such a little boy could play the violin so well.
4.表示坚持、命令、建议、要求的名词从句的语气要用虚拟语气,结构为should + do, should 可省略
It was ordered that all the soldiers____to the front.
A.should send
B.must be sent
C.should be sent
D.must go
5.whoever = anyone who + 定语从句
whomever=anyone whom +定语从句
What/whatever , when / whenever , where / wherever 的含义基相
同，只是后者比前者语气更重。在意义上也有细微差别：
whatever 含义为anything that
whenever 含义为any time when
wherever 含义为any place where
改错：
1)Who leaves the room last ought to turn off the lights .
2)Mary hopes to become a friend of whomever shares her interests .
6.名词从句中须使用陈述语序
7.主句谓语动词是过去时态，从句也必须使用过去相应的时态。(客观真理、格言谚语除外)
