以下是引用apple0000006在2008-6-7 16:08:00的发言：

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

从逻辑意思来解决: 注意believe后面的宾补是 type , 而distant supernova explosion本身不可能是一个type只可能是type的一种, 所以要用到词组: of a type, 可以把 A排除, 虽然从语法上没错

B one that they believe it to be 既然已经用定从修饰one 了, 则belive后面不需要在出现代词it , 冗余

C明显的罗嗦, it 与 one 重复

D  believe that  宾从后面没有主语

E best  one( 定从先行词坐宾语,省略that) they believe to be of a type

E is best.


Idiom: believe to be.
Do not need THAT following ONE.

这道题目，一开始我选A
看到答案，仔细考虑后，有两点体会
1. one和that 都是代词，一起使用，重复了
2.be+n和be+ of n的区别，of n相当于形容词，type 是量词，单独的使用量词，是不完整的，可前加of 形容词话，总结个规律，a type of，a piece of等量词，如果后面没有of，前面就要加of
