题目

请问Any specific reason I should know about in case people ask where you are.句型结构?这里的主谓宾和从句?
Any specific reason I should know about in case 这里和后面是不是应该有个链接词?people ask where you are.从句之间链接不都是需要连接词的吗?只是有的连接词被省略了?
in case people ask where you are.是一个以in case 引导的条件状语从句，请问这个状语从句的连接词是省略了if，还是in case 就代表if了？
