求指导Li Po wrote the famous poem when he made a tour to {what}was once a battlefield.
Li Po wrote the famous poem when he made a tour to {what}was once a battlefield.这里的宾语从句为什么用what引导,而不能用where呢?
答
从句was once a battlefield 缺少主语,所以要用what,而where是关系副词不能在从句中充当主语
答
what 是连接代词,where是连接副词,连接代词一定可以在句中充当语法成分(主 宾 定 表)而连接副词只能充当状语,看原句,缺少主语成分,所以只能用what, where不能充当主语成分
