关于名词性从句中的what
cet6的语法书在讲表语从句中说
what 作连接代词 That's what we should do
waht 作关系代词 china is no longer what she used to be
这里又是凭什么区分的呢?
关系代词不是要像定语从句中如which that一样既做连词又做代词?
如 What he said at the meeting is important
为什么what似乎在名词性从句中只做代词却称为关系代词
无敌英语语法一会儿称what为连接代词如who whoever
一会儿又称关系代词着实让人不明
请问关系代词和连接代词到底有何区别 what在名词性从句中到底属于那种
还是要分情况 希望大家指教 这个问题困绕我许久

连接代词在引起从句时,都称为连接代词,包括who/whom/what/where/when/why/how,它们可以引起: a.主语从句:
It hasn’t been announced who won the prizes.还没宣布谁获奖.
It is clear enough what she meant. 她是什么意思很清楚.
b.宾语从句:
I don’t care what they think. 他们怎么想我不管.
Ask her which he wants. 问她要哪一个.
c.表语从句:
The question is who(m) we should trust.问题是我们应当相信谁.
What I want to know is which road we should take.我想知道的是我们应走哪条路.
* 连接代词还可引起不定式,都用作宾语或介词的宾语:
Tell him what to do. 告诉他怎样做.
Lucy can’t decide which to choose. 露西不能决定选哪个好.
They exchanged views on the question of whom to elect. 他们就该选谁的问题交换了意见.
关系代词
(1) 关系代词用来引导定语从句.它代表先行词,同时在从句中作一定的句子成分,例如:The girl to whom I spoke is my cousin. 跟我讲话的姑娘是我表妹.(该句中whom既代表先行词the girl,又在从句中作介词to的宾语.)
(2) 关系代词有主格,宾格和所有格之分,并有指人与指物之分.在限定性定语从句中,that 可指人也可指物,见表:
限定性 非限定性 限定性
指 人 指 物 指人或指物
主 格 who which that
宾 格 whom that that
所有格 whose of which/whose of which/whose
例如:
This is the pencil whose point is broken.
这就是那个折了尖的铅笔.
(whose 指物,在限定性定语从句中作定语)
He came back for the book which he had forgotten. 他回来取他丢下的书.
(which指物,在限定性定语从句中作宾语,可以省略)
(3) 关系代词which的先行词可以是一个句子,例如:
He said he saw me there, which was a lie.
他说在那儿看到了我,纯属谎言.
说明: 关系代词that在从句中作宾语或表语时可省略, 例如:
I've forgotten much of the Latin I once knew.
我过去懂拉丁语,现在大都忘了.
He's changed. He's not the man he was.
他变化很大,已不是过去的他了.
注释:关系代词在从句中作宾语时可省略,that在从句中作表语时也可省略.
非限定性定语从句中,不能用that作关系代词.

只有在定语从句中的that/which/who/whom/where/when/why/whose才被称作关系代词;而名词性从句中的连接词有三种,即:that(没有实际含义,只起连接作用,只有在宾语从句中才可以省略);if/wheter(是否);wh-特殊疑问词。
what在名词性从句中通常做主语、宾语和表语。
Shanghai is no longer what it used ...

其实what /which /who /whom /whose等词语,在简单句中当然叫疑问代词,在定语从句中叫关系代词(因为定语从句又被称做关系代词),引导名词性从句中被叫做连接代词;
类似地,when /where/ why等词语,在简单句中叫疑问副词,在定语从句中叫关系副词,引导名词性从句中被叫做连接副词
