who与which在连接名词从句的区别

Answer 1

名词性从句包括主语从句、宾语从句、表语从句、同位语从句四种。
1 主语从句
that可以引导主语从句，which不可以引导宾语从句，所以that 和 which 在主语从句中的区别在于前者是主语从句关系代词，后者不是主语从句关系代词。
2. 宾语从句
that和which都可引导宾语从句，区别在于前者引导动词的宾语从句，在句中充当连词。
例句：I think that he’ll be all right in a few days.
后者引导介词的宾语从句。
例句：Can you tell me which you like best ？
3 表语从句
that 在表语从句中仅起连接作用，无实际意义，在句中不做任何成分，不能省略。
which 在引导表语从句时,常充当定语，表语表示哪一个，哪一些。如：I read about it in some book or another, but what I don’t know is which (book) it is.
4 同位语从句
两者在同位语从句中的区别在于前者做连词，后者做连接代词。同位语从句对先行词进行解释说明，整个同位语从句等于先行词，定语从句的引导词等于先行词。
引导词有1.that eg：The idea that you can do this work well without thinking is quite wrong。
2.whether eg：The question whether we should call in a specialist was answered by the family doctor。
3.连接代词what, who, whom, whose, which
1).I have no idea what size shoes she wears
2).I have no idea which wine is best—it’s a matter of personal taste.
3).The question who will take his place is still not clear.
