9. Astronomers at the Palomar Observatory have discovered a distant supernova explosion,one that they believe is a type previously unknown to science. 这里的one是指代前边的短语中的核心词explosion的，而后边的从句是修饰a distant supernova explosion整体的。应该是逻辑意思不对。下边的那个句子就没有这个问题。个人见解，欢迎拍砖

谢谢你的回复哦~

但我个人觉得one指代explosion和整个a distant supernova explosion没啥区别，因为a distant supernova explosion中，前面的修饰语都可以省略的，剩下中心语explosion。

逻辑意思不对啊，后边的句子是用来修饰这个特定的explosion的。

1. 这里都是同位语 + 定从的格式

2. 用 is 还是 to be 取决于前面的动词， agree 一般接 that 从句 (that 在宾从中一般省略); believe A to be B, A被前面的关系代词取代，所以省略.
