请问一句英语的语法结构,原句是“I like to eat before I go to bed,which i know isn't good for you.” which是指代前面整句话呢?还是只to eat before I go to bed.还有就是know 和isn't怎么两个动词出现在同一句子里呢?

请问一句英语的语法结构,
原句是“I like to eat before I go to bed,which i know isn't good for you.” which是指代前面整句话呢?还是只to eat before I go to bed.还有就是know 和isn't怎么两个动词出现在同一句子里呢?

I know (that) "to eat before one goes to bed" isn't good for you.
这样重新组织一下就可以理解了

which是指代前面整句话,定语从句,要么指代一个句子,要么指代一个名词,哪有指代不定式的
I know 是一个插入语,把它当划掉,只会干扰到你的理解
