The town ___ I stayed during my winter holiday is

that为什么这里要用where呢;hometown.A.B.where ？
而The village ___ I visited last year has changed a lot.这个句子要用that 呢The town ___ I stayed during my winter holiday is my grandfather'

第一个句子 先行词the town在定语从句中做状语，所以用关系副词where
还原一下就是， I stayed in the town during my winter holiday

第二句的先行词the village在定语从句中做宾语，所以使用关系代词that
还原一下就是 I visited the village last year

你好！ that在这充当它的宾语，所以 I stayed构成一个句子，所以，后面必须跟个名词，所以空格处填状语。visit为及物动词stay 为不及物动词 仅代表个人观点，不喜勿喷，谢谢。
