求大佬分析下该句子结构。感谢！

I am sure i speak for others in saying parent who encourage learning at home ultimately have kids who perform at higher level in class .求大佬分析下该句子结构？

Answer 1

I(主语)am sure (系表结构的复合谓语) [I speak for others](省略that的宾语从句)
[in saying parents (who encourage learning at home)(定语从句修饰parents) ultimately have kids (who perform at a higher level in class)(定语从句修饰kids)](补语).
这句话的意思是：
那些鼓励孩子在家学习的家长，他们的孩子最终都能比在课堂上学得更好，我这么说确实是在为他人辩护。

Answer 2

先是一个宾语从句，然后parent后面是第一个定语从句，再是kids后的一个定语从句
