求帮忙分析一下这个英语句子结构。

someone i know who i think is a good parents is my mom

Answer 1

someone是主语，is my mom构成句子的谓语和表语。中间 I know who I think is a good parents 定语从句用于修饰主语。

Answer 2

someone 【主语】i know who i think is a good parent【定语从句】 is my mom【系表】
定语从句中：
i know 【主谓】who i think is a good parent 【宾语从句】
宾语从句中： i think【主谓】， who is a good parent【主系表】
