Question

英语语法求解释

Few of the cultural traditions and rules that today allow us
to deal with dense populations existed for these people accustomed to household
autonomy and the ability to move around the landscape almost at
will.
中Few of the cultural traditions and rules为主语allow 为谓语us 和 dense populations existed for these people为双宾语，那么that today 是不是时间状语？

Answer 1

Few of the cultural traditions and rules为主语，that today allow us to deal with dense populations是定语从句，修饰the cultural traditions and rules，existed是谓语，for these people是状语，
accustomed to household autonomy and the ability to move around the landscape almost at will是定语，修饰people，其中household autonomy and the ability to move around the landscape almost at will是介词to的并列宾语

Answer 2

that是主语从句的引导词，today是时间状语

追问

that是主语从句的引导词的话 那that后面的应该是主语啊 。。。。。。。但是that在主语后面又不充当成分，貌似没见过这种主语从句。。。

追答

that在这里可以充当主语从句的主语

追问

名词性从句that可以充当成分？ 没听说过 给个例子？

Answer 3

不是，我觉得应该是定语

Answer 4

看不懂
