where在宾语从句中

Question

Where I was last night.I was后不是缺成分吗为什么用where(宾语从句）

Answer 1

Where I was last night. 不缺成分；I was后缺的就是where表示“的地方”，宾语从句中where提前，问 昨晚我在哪里。

Answer 2

He knew where I was last night.
where I was last night这部分充当knew的宾语，陈述句排序应该是：I was where last night（我昨晚在哪儿），where是疑问词，所以要提前追问

where不是关系副词吗，能充当表语吗

追答

where还有代词的意思，I was where就是指代的某个地方
