Question

麻烦帮忙分析一下这个句子中同位语从句的成分，谢谢！

The notion that learning should have in it an element of inspried play would seem to the greater part of the academic establishment merely silly, but that is nonetheless the case.

Answer 1

解释如下
同位语从句为：
that learning should have in it an element of inspried play would seem to the greater part of the academic establishment merely silly
其中learning为主语，seem为谓语，silly为宾语。should have in it an element of inspried play是learning的定语；to the greater part of the academic establishment为状语。

Answer 2

1、句子成分划分：【The biggest problem 主语，定语从句先行词】 【for most plants介词短语，主语的定语】, 【which can't just get up and run away when threatened 非限制性定语从句】, 【is谓语动词】【 that animals like to eat them表语从句】. 2、when threatened 省略形式的时间状语从句。补充完整是： when【 they are】 threatened 当它们受到威胁时 3、that 引导的表语从句.表语从句，是名词性从句中的一种。在所有名词性从句中，that只起连接句子的作用，没有任何实际意义，也不充当句子成分（引导定语从句，才做从句句子的主语或宾语）。 祝你开心如意！
