whatever引导的是什么从句

It means spending time enjoyably on whatever relates to the language you're learning.

Answer 1

看whatever引导的从句在主句中做什么成分。如果是做主语、宾语、表语、同位语，则引导的是名词性从句，否则便是状语从句。
例句：Whatever you do will not influence me. 你无论做什么都影响不到我。（主语从句）
Whatever you do, I will support you. 无论你做什么，我都支持你。（让步状语从句）
如果还看不懂，欢迎追问。
