从说话目的，句子结构和语法层次分析这句话

they are trying to find out whether there is something about the way we teach language to children which in fact prevents children from learning sooner.

they（主语） are trying（谓语） to find out（补语，不定式表目的）（whether。。。后面是宾语从句） whether there（主语） is（系动词） something（表语） about the way （定语）we teach language to children（the way的定语从句） which in fact prevents children from learning sooner.（做there be句子的定语从句，我觉得这里是个非限定性定语从句，打个豆号好些）

whether there is something about the way 做find out 的宾语 就是宾语从句

the way we teach language to children 定语从句 先行词the way that we teach language to children

which in fact prevents children from learning sooner. 定语从句 先行词 the way 这个 先行词 我还在考虑 有点不好找
