i have never been to rome but that's the city i'd most like

i have never been to rome but that's the city (i'd like to visit) 括号里是定语从句,省略了关系代词 that / which,这个关系代词给visit 当宾语的.说成 where I most like to visit 反而不对了
如果想说“是我最想去的那个城市”,可以说成：the city I can't wait to visit （迫不及待想去）,或者 the city I'd like to visit at the first chance
再问： i have never been to rome but that's the city where i most like to visit。 做状语不行吗，详细点
再答： but that's the city (i'd like to visit)，这是里的关系代词 that 给visit 当宾语的，visit是及物动词，一定要有宾语，所以 这个定语从名不是缺状语，而是缺宾语
