The platform canceled the program, a move that its boss said was aimed at “making a better one.”

——由于 a move（举措）不是指the program，而是指前文整个内容，因此不能是program的同位语了，而是前文的非限制性定语，用来说明、解释、评价前句的内容。相当于：The platform canceled the program, which was a move that its boss said was aimed at “making a better one.”

that its boss said was aimed at “making a better one.” 是 move 的定语从句，且是一个嵌入式的定语从句。

They called for regulation of what it called the “chaos” of the industry.

——what 引导名词性从句，是一个笼统的叫法。它作主语时，叫做“主语从句”，作宾语时叫做“宾语从句”，本句 what it called the “chaos” of the industry，就是作 of 的宾语，因此可以叫“宾语从句”。

what it called the “chaos” of the industry，由于 what 没有疑问概念，它实际是一个融合性关系代词，引导后面这个名词性关系分句，作 of 的宾语。

◆ 给网友普及一下关于从句的语法知识：

由一个主句和一个及以上的从句构成的句子，叫做复合句，也叫主从句。主句和从句分别有自己的主语和谓语，但从句只是主句中的一个成分，不能独立存在。根据在全句中的不同作用，从句可分为“状语从句”、“定语从句”和“名词性从句”，称为英语中的“三大从句”。其中，名词性从句包括：主语从句、宾语从句、表语从句、同位语从句。这四种从句在复合句中的作用相当于名词，所以，统称为“名词性从句”。

名词性从句，其实就是让句子去充当一个名词的作用；用一个从句去描述一个名词所无法做到的更加丰富的语义，在一个更大的句子里面充当主语、宾语、表语和同位语。因此便有了主语从句、宾语从句、表语从句和同位语从句。

. The platform canceled the program,( which is 省略)a move that its boss said was aimed at “making a better one.”

解答：a move可以看作省略which is非限制性定语从句，that its boss said 定语从句修饰前面名词a move,关系代词在定语从句that its boss said作谓语动词said的宾语成分,同时在定语从句that was aimed at making a better one作主语成分(备注：关系代词which指代前面整句话内容）

2. They called for regulation of what it called the “chaos” of the industry.

解答：of what it called the chaos of the industry 为介词短语作后置定语修饰regulation, of what it called the chaos of the industry为介词of+what引导的宾语从句。

what it called the chaos of the industry有以下2种理解（it called+宾语+宾补）

(1) what作谓语动词called的宾语，the chaos of the industry为宾语补足语。

(2)what作宾补,the chaos of the industry作谓语动词called宾语。

总结：连接代词what在宾语从句中可以充当“宾语”或者“宾补”成分。

备注：名词性从句包含4种从句：即“主语从句，宾语从句，表语从句，同位语从句”，换句话说，以上4种从句都属于名词性从句其中一种。
