把og上关于one that的题贴一次

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 of 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.

和大全809比较，什么原因使得一个要用one that，一个要省掉that呢？

能不能详细解释一下？

是one在定语从句里的成分吗，og9里面是作从句的宾语，大全这题是作从句的主语。是因为这个差别吗？

有道理，谢谢。那么以后看到one that 这种搭配就得好好想想了，复杂啊
