请教英语高手，which都不能引导主语从句，表语从句和同位语从句，如能，请给出例句，多谢啦

能。 主语从句，表语从句和同位语从句都叫做名词性从句，which、what、who、whom、whose连接代词都可引导，例如：
Which style is more acceptable(接受）hasn't been discussed yet。主语从句
That is which I gave you.表语从句
The idea which I gave you is no bad.同位语从句
其它引导名词性从句的关联词还有
连接词that、if、whether
连接副词when、where、why、how
复合代词和复合副词whatever、whichever、whoever、wherever、whenever、however

能啊
