8.  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.
(B) and that is believed to be
(C) and it is believed to have been
      答案是C，请教B中的that指代问题，我是凭感觉判断这里不应该用that指代，不知道

这个错误用理论来归纳是什么错误？？？记得好象语法书上说过的，但是我找了半天，没

找到。

gmat里面,that, this, these,those从来不单独用,只能是this dog, those people.还有,也不能用do this, do that, do it,只能do so. 当然,这只局限于gmat语法里面.

dreadpower

但是比较中，经常用that和those指代前面的名词啊~~~

这种情况它们后面一般有东西来修饰的,不能叫单独使用吧.我的意思是不能this is......these belong to ...,这些是gmat里面尽量避免的
