标题: 求助：OG中的 o/ 是什么意思？

新手问问傻傻的问题：下面的那个o/什么意思啊？

9. Astronomers at the Palomar Observatory have discovered a distant supernova explosion, one that they believe is a type previously unknown to science.

(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

Choice E is best. The pronoun that in A and B should be deleted, since the pronoun one is sufficient to introduce the modifier and the sentence is more fluid without that. In B and C, it and that it are intrusive and ungrammatical: the idiom is "believe x to be y." In the context of this sentence, the infinitive to be is more appropriate than the limited present-tense is in referring to an event that occurred long ago but has been discovered only recently. Finally, A, B, and D lack o/and so illogically equate this particular explosion with the whole class of explosions to which it belongs: it is not a type but possibly one of a type.

多谢colacat！

不过是of的话，后面应该有个名词啊？

Finally, A, B, and D lack of and so illogically equate.......

lack of 什么呢？

就是这三个choice缺少of

这是说他们的错误再哪里啊

因为没有of,所以造成逻辑上的错误
