此类问题老是做错。。。

Astronomers at the Palomar Observatory have discovered a distant supernova explosion, one that they believe is a type previously unknown to science.  E
(A) that they believe is
(B) that they believe it to be
(C) they believe that it is of
(D) they believe that is
(E) they believe to be of

ABCDE分别如何还原？

upupup....

首先明确, one...是什么成分
前面的句子结构主谓宾是完整的，所以后面, one...应该是独立主格结构

所以排除有that的选项，选E

独立主格一般放在句首或句尾作状语，表示伴随原因、条件、状态等

一般独立主格(n.＋n./-ed/-ing/介词短语/adj短语)与主句形成松散的逻辑关系

with型独立主格(with n.+ -ed/-ing/adj/介词短语)与主句形成紧密的逻辑关系

each型独立主格(复数名词结尾, each+介词短语/adj短语/-ed/-ing)强调句尾名词

one...结构即使是独立主格结构，为什么that要省略？that后面完全可以是个modifier修饰这个one的啊。。。

首先看意思，A发现了一个什么爆炸，这个爆炸他们认为是一种类型的爆炸，这种类型的爆炸以前不被科学所知。
那么A,B,D就出现了歧义，因为这种爆炸是of a type,而非直接是a type。剩下C,E中我感觉C有点啰嗦吧，that it is是废话。所以只好E咯。

独立主格的几种常见形式都没有that，因为如果使用that从句，不如放弃独立主格而直接用定语从句

如果简单记忆，就记住独立主格出现that多有问题

wait...这么一说我觉得one...结构更像同位语！

我觉得是同位语结构，在定语从句中that/which可以省略。首先，believe的用法是believe to be，所以ACD排除。B it多余，所以就是E。
believe的其他用法是believe sth.; believe + that 从句
另外，从逻辑意思上来看，be of结构表明爆炸是一个爆炸类型中的一种，也更符合科学事实一些。

不好意思，我晕了你说的对，是同位语，不是独立主格。

前面我说错了

下面是我找到one of作同位语的一些例子：
