大全145,问这几个that,不用分析题目,回答问题就好,谢谢。
1.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
各位童鞋们,以下是大全注释的解释:前面one that they believe is , 正常顺序they believe that one is...变成one+that定语从句, 因为one不作主语,所以一般省that, 后面believe +that宾语从句,在定语从句中出现的宾语从句,that一般也省,所以应该是one they believe is,不过这里believe宾语从句不如believe to do好。
但是我不太理解前辈的解释。第一one+that在one不做主语的情况下that要省略?为什么啊?第二one that they believe is这个结构中that是做什么成分啊,不是they believe的宾语么?怎么注释里解释说这个that 引导的是one的定语从句,然后they believe之后的that作为宾语要省略呢?
