大全250-128，没有讨论过的问题。请指点

128. During the Renaissance, scholars were uncertain as to the location of Troy, and by the eighteenth century many historians doubted that Troy had ever existed.

(A) doubted that Troy had ever existed

(B) doubt that Troy has ever existed

(C) were in doubt as to the existence of Troy

(D) were doubtful concerning Troy’s existence

(E) had doubts about Troy’s ever existing

答案A

我的疑问是doubt后面可以用that引导的从句吗？我记得只有don't doubt才可以阿。

doubt 后面只能用whether(if)啊。请指点。

哎!好冷清阿。

up一下吧

查了字典的，确实有doubt that的用法。可能还是我的记忆出了问题。哎！老了！......

不过，有谁能讲讲一下两个句子的差别呢？

by the eighteenth century many historians doubt that Troy had ever existed.
