he works in a city which/that is far from the village!

he works in a city which/that is far from the village!
这里的which/ that 的作用,能不能用where啊
解析：不能够使用where,where是副词,在句子中做状语,不能做主语,.is 是谓语,前面缺少主语.which,that可在定语从句中充当主语和宾语
what most parents fail to realize,_____,is that today`s children lack
这里为什么可以填 though 啊 ,实在想不通,求英语达人大神们求解啊
解析：though 这里是插入语,然而的意思.
翻译：大多数父母没有认识到的,然而正是目前的孩子们所缺少的请问he works in a city which/that is far from the village!这里的that is能不能省略啊，为什么啊he works in a cityfar from the village.可以省略 that is，这样的话就是一个简单句，而且far far from the village 介词短语直接做定语。修饰city
