请英语大神帮忙分析一下这两个句子的语法结构吧！！

Question

句子：1. I asked her why she smiled at me that day.
2. It is where we do interviews with the big sports stars.
请问这两个句子是什么从句，各部分做什么成分？

Answer 1

1 宾语从句 2 定语从句
宾语从句是V+疑问词+一个句子。如 I asked her why she smiled at me that day。I asked her是主句，后面的是从句。
定语从句是名词后+连词（conj.）+一个句子。如It is where we do interviews with the big sports stars.where是地点we do interviews with the big sports stars是修饰前面的地点的，是从句，前面的是主要部分

Answer 2

I (主语)asked（谓语） her（宾语） why she smiled at me that day（宾语从句）
It（主语） is（谓语） where we do interviews with the big sports stars（表语从句）.

Answer 3

1 宾语从句
2 表语从句
