is this old castle()i visited last summer vacation?为什么不能填where

问题描述:

is this old castle()i visited last summer vacation?为什么不能填where

应该是the one
此句还原的话可见缺表语,同时定语从句缺宾语,因为visited 是及物动词
where 是副词,不能作宾语为什么不能填that从局部看可以, 但就句子结构来看不行, 还原一下你看:
this old castle(主语)(that)i visited last summer vacation(定语从句) is(系动词).......(is 后面缺表语)
