Could you tell me who is waiting for you at the school gate?
就是who做主语的陈述语气啊.这样可以的.为什么可以这样??who 不是疑问词吗??who是疑问词没错,不做从句,本身也确实是疑问句。如who is waiting for you at the school gate?因为who在句子中成分是主语,所以不需要will, could, do, is这样的词提前。所以作为宾语从句的时候也不会有系动词或情态动词提前了。简而言之就是who在这句中是主语。比如:1....then you will find who is your best friend.2.The question(matter) is who is Kate?3.I have no idea where you are.这些句子对吗?3句都对。为什么??前2句和之前是道理一样。第三句where不是主语啊,所以you 和are 在后面的从句里换了位置。那第三个句子是什么句子??第三句可以分成2个句子。I have no idea 我不知道where you are 你在哪里连在一起就是I have no idea where you are。之所以不是I have no idea where are you。是因为where不在从句中做主语,所以需要are在you前面。如果是who,做主语成分就不需要提前。整句是宾语从句。
