标题: OG9 believe x to be y / that ?
og 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 isE


(E) they believe to be of


believe 可以加 THAT 也可以是TO BE ,这T ,ETS 对两者的区分是说-


In the context of this sentence, the infinitive to be is more appropriate than the limited present-tenseis in referring to an event that occurred long ago but has been discovered only recently.(在表示一个过去很长时间以前发生的事情直到现在才被发现,用不定式to be 表示比 the limited present-tense 表达要好!)



看的忽忽突突的感觉!如果D 加上OF 可以选择D 吗???

我想還是不能,理由是加了of,D選項和C選項相比還是少了個主詞,可能還更不如C

believe that,後面是要引導一個子句的,不能直接is ....

one they believe that is of, 這樣結構不行

改成one they believe that it is of 可以选了了.但是罗嗦
