pay attention to 后面为什么接不定式

Our teacher insisted that the key word worth paying attention to be underlined before class.《徐广联大学英语》。

请问worth是后置定语吧，pay attention to 中的 to 不是介词吗？为什么后接be underlined?是什么语法结构？（看答案中说省略了should是怎么回事？）

我可否这样理解 worth paying attention to 为 word 的第一层修饰，should be underlined (被动语态）修饰从the key 到 to的全部？

你的理解是对的：

①insisted 后面的 that 引导的是宾语从句；

②worth paying attention to 为 the key word 的修饰语；

③should be underlined (被动语态)不是修饰从the key 到 to的全部，它是主语the key word 的谓语部分。

④由于 insist（表示“坚持要”）后面接 that 从句时，通常用“should+动词原形”（其中的should可以省略），即原句相当于：

Our teacher insisted that the key word worth paying attention to (should) be underlined before class.

又如：

The detective insisted that he (should) have a look. 警探坚持要查看。

I insisted that he (should) go with us. 我坚持要他和我们一块儿去。
