Luckly,we'd brought a road map without ____ we would have lost our way A it B that C which D this
句子意思：幸运的是,我们带来一张公路地图,要是没有这张地图,我们可能就要迷路了
答案解析,定语从句,答案为C ,介词+which 的用法,指代前面先行词map
副词做状语,修饰整个句子:luckily
主句主语:We
主句谓语:had brought
主句宾语 a road map
引导定语从句关系代词 which （在定语从句充当介词without 宾语）
从句主语 we
从句谓语would have lost
从句宾语：our way
从句状语：without which（介词without+关系代词which 的用法 (没有这张地图）
再问： 介词without+关系代词which 怎么用
再答： without which 就相当于without the map 关系代词=替代前面先行词map地图，希望明白，并采纳，谢谢！
