英语句子分析？

Environmental pollution is a term that refers to all the ways by which man pollutes his surroundings. 帮忙详细分析一下这个句子的成分！

Answer 1

Environmental pollution主语，is系动词，a term表语，that后的句子为term的定语

Answer 2

主句是Environmental pollution is a term。that refers to all the ways是定语从句，that 代替a term做定语从句的主语，也可以使用which，不能省略。by which man pollutes his surroundings是第二个定语从句，修饰先行词ways。环境污染是一个术语，指的人类污染其周边环境的种种途径和方式。
