on which 是定语从句还是状语从句？

Question

They have started a special day called Buy Nothing Day on which they don’t want anyone to go shopping.

on which 的用法对不对？有没有其他的方法来描述这个句子？
on which在这里引导是定语从句吗？

Answer 1

你好，很高兴为你解惑：
They have started a special day called Buy Nothing Day on which they don’t want anyone to go shopping
= They have started a special day called Buy Nothing Day when they don’t want anyone to go shopping
他们开创了一个“什么都不买日”，在那一天他们不想任何人去购物
这里是定语从句，when/on which修饰先行词day，在定语从句中，它们充当状语成分。
on which = on the day 在那天
望采纳，祝开心~！！！

Answer 2

状语从句
