一道GMAT改错题
A huge flying reptile that died out with the dinosaurs some 65 million years ago,the Quetzalcoatlus had a wingspan of 36 feet,believed to be the largest flying creature the world has ever seen.
答案说believed to be 不对.
好的答案一定会追加分数

A huge flying reptile that died out with the dinosaurs some 65 million years ago 同位语
Quetzalcoatlus主语 had 谓语
a wingspan of 36 feet 宾语
,+believed to be the largest flying creature the world has ever seen.
首先,这里：,+过去分词优先做主句谓语的伴随状语,这个伴随的动作性是被动,也就是主语被动被belived to be,是OK的
但是过去分词作伴随状语还有时间性,其时间是在主句谓语动词的时间之前.
但是从句意来看,这个时间上的差距,是明显不存在的.
其次,过去分词可以就近修饰做定语,那么,这里就产生了歧义,修饰feet,明显不对.
所以,这句话用过去分词表主句谓语的伴随,不仅在句子时间性上出现错误,而且引起修饰歧义.不是好的选择.
