句子剖析

To ensure its grip on the message put out by its domestic and international broading service,including CGTN,the government consolidated them in March into a single media group as known Voice of China .

括号its name````里的内容，好像没谓语 所以不是一个完整的句子对吗？

that of ，that 又是指代什么呢?

括号内不是一个句子，而是独立主格结构作状语，对主句作补充说明。假如去掉括号，则用逗号和主句隔开。其中echoing为目前分词，its name in English为目前分词的逻辑主语。that为名词替代词，替代前面出现过的一个特指的单数名词或不可数名词，在这里that替代the name.

另外，网友句子中的 as known为笔误，应为 known as.
