Question

请帮忙分析一下以下句子的结构，谢谢！

People who support gun rights generally look to the second part of the Second Amendment, the part that says "the right of the people to keep and bear arms."
谢谢各位！你们说的我都理解，就是不明白为什么前后两个句子要用逗号隔开？？？这是什么语法啊？

Answer 1

People who support gun rights generally look to the second part of the Second Amendment, the part that says "the right of the people to keep and bear arms."

people who support gun rights是一个定语从句，修饰people
后面look to 是谓语 the second part of the Second Amendment是宾语
逗号后面是second part的同位语，解释说明second part的具体内容

翻译过来
支持持枪权的人们看到的主要是第二修正案的第二部分，里面说到：人们有权拥有与携带武器“

Answer 2

People who support gun rights generally look to the second part of the Second Amendment, the part that says "the right of the people to keep and bear arms."
逗号前的People who support gun rights generally look to the second part of the Second Amendment是一个完整的主谓结构，逗号后面由the part 引导的从句是前面the second part 的同位语从句

Answer 3

people是主语，who support gun rights generally 是定语从句，look to是谓语，the second part of the Second Amendment是宾语 ，that says "the right of the people to keep and bear arms."是同位语从句，解释说明the part
