同样是名词性从句的连词,what和which有什么区别

就是what与which的区别.
还有一个是what有纯名词性的,如:What he said is wrong.
which只能是由一个疑问句变来的名词性从句.
作为疑问代词what和which的区别是:
后者给定选择的范围.前者不限.
如:
Which do you like eat,A or 回答在A或B中选一个.
What do you like to eat?回答是开放性的.
两个词都可以作定语,后加名词如:
Which book do you want to buy?
What book do you want to buy?
问:什么叫纯名词性
不带疑问性质的=名词+that-定语从句的.
这是我发现的关于名词性从句的一个细节.
这种名词性从句作主语时,是不可以用it来代替而后置的.
比如:The books that I bought yesterday are very interesting.不能说成:It is very interesting the books that I bought yesterday吧?同理,What I bought yesterday is very expensive.不说:It is very expensive what I bought yesterday.
但是:What we should do next is still unclear.--> It is still unclear what we should do next.常这么说.
