阅读文法时，
常常搞不清楚连接副词与副词子句连接词
It is too far from Taipei; hence, we don't go there today
hence当连接副词用
上句也可以写成
It is too far from Taipei. Hence, we don't go there today
这时候，Hence可以取代成其他副词子句连接词
Now that you know the matter, let's go outside for relax.
Now that当副词子句连接词用
请问，连接副词(hence)是修饰逗号后面的整句吗?
而且，连接副词在何种状况下可以取代成副词子句连接词
