优质解答

which kind of问到是‘哪类.’,一般后面跟单数名词或不可数名词表一类（也就是说这里的名词没有数的概念而只有类概念）,所以你可以问
which kind of method can you learn from the passage?
从这个段落你学到了哪种方法.
which kind of water is that?It's salt water.
这是哪类水?是盐水.
但是在特定条件下后面也可以跟复数名词：
which kind of methods can you learn from the passage?
从这个段落你学到了哪类方法.
这里说明你学到的方法必然是指一类中有多个的.
