答案是C吗？GG有什么不解的地方？

根据主语samples判断谓语为复数，排除AB；and 后边要补出are，排除D；be dated at这种用法好像没见过吧，被我排除了，剩C。

这题最后选什么啦？C OR E？我觉得at 应该指具体某点时间。

作者: stevezhao 时间: 2006-12-21 17:51

记得OG11中有一题和这个类似，也是在to be 和at中选一个，当时的解释是过去一直存在的东西最近被发现，要用to be，而不用at。我的 OG11是pdf的，没法search。哪位NN再看一下？

找到那到题了，不知OG的解释是否也适用于这个28题：

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.
