1.连接代词是所有可以引起从句的疑问代词,比如what, who等,在从句中作主语或者宾语等

主要包括who, whom, what, which, whoever, whatever, whichever, whosever 等

如:

Ask her which she wants. 问她要哪一个。 (which在从句中作宾语)

I don’t know whom you should depend on?我不知道你该依靠谁.

2.连接副词是用于引导从句的疑问副词,比如where, why等,在从句中作状语

主要的有when, why, where, how 等

如:

I don't know why he is here. 我不知道他为什么在这儿。(why在从句中作状语)
