层次分析法，作为现代英语语法的成果，为拆分英语句子提供了一种系统的方法。通过这种方法，我们可以更清晰地理解句子的结构和各个组成部分。以“This suggests people use relevant evidence about AI in a biased manner to support their existing attitudes, a deep-rooted human tendency known as “confirmationbias””为例，我们可以将其分解为以下几个部分：

主语：This

谓语动词：suggests

宾语：people use relevant evidence about AI in a biased manner to support their existing attitudes, a deep-rooted human tendency known as “confirmationbias”

接下来，我们继续深入拆分宾语：

主语：people

谓语动词：use

宾语：relevant evidence about AI

状语：in a biased manner

不定式分句：to support their existing attitudes, a deep-rooted human tendency known as “confirmationbias”

在这个不定式分句中：

逻辑主语：people

谓语动词：to support

宾语：their existing attitudes, a deep-rooted human tendency known as “confirmationbias”

进一步拆分宾语：

限定词：their

前置修饰语：existing

中心词：attitudes

后置修饰语（同位语）：a deep-rooted human tendency known as “confirmationbias”

继续深入：

限定词：a

前置修饰语：deep-rooted

前置修饰语：human

中心词：tendency

后置修饰语（-ed分词分句）：known as “confirmationbias”

层次分析法区分了传统语法中的非谓语动词与谓语动词概念，将非谓语动词视为短语，而谓语动词则形成分句。理解这些结构有助于我们更准确地解析复杂的英语句子。
