festival后面可以接when引导的定语从句吗

问题描述

老师说下面句子中的 when they can dress up and go to their neighbours’ homes to ask for sweets 是 when 引导的定语从句，修饰 festival。我不太明白，请专家帮我进一步分析一下，谢谢！

It is now a children’s festival, when they can dress up and go to their neighbours’ homes to ask for sweets.

老师答疑

龙老师：

老师说的是对的，句子中的when they can dress up and go to their neighbours’ homes to ask for sweets 是 when 引导的定语从句，修饰 festival。

festival 后面完全可以接 when 引导的定语从句，这里的 when 相当于 on which。即：

It is now a children’s festival, on which they can dress up and go to their neighbours’ homes to ask for sweets.
