Question

这个句子是什么语法结构！急急急，看不出他是并列句还是啥简单句？

the maker philosophy echoes old ideas advocated by John Dewey,Montessori,and even ancient Greek philosophers,as we pointed out recently.

Answer 1

这句话是复合句，包含一个as引导的定语从句。
the maker是主语；谓语动词是echo三单形式，释义重复；old ideas是宾语；advocated是分词形式的非谓语作后置定语，用于修饰old ideas；old ideas advocated by A，B and C解释为被A，B，C所提倡的旧观点。as we pointed out recently解释为就像我们最近指出的那样。
句子主干为 S echoes old ideas，as we pounted out recently.

Answer 2

the maker philosophy是主语，echoes是谓语动词，并列结构old ideas advocated by John Dewey,Montessori,and even ancient Greek philosophers作宾语，as we pointed out recently是方式状语从句修饰“谓语动词 + 宾语”。语法书称为“主从复合句”。
