269 During the Remaossance, 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 （A ）

B) doubt that Troy has ever existed

C) were in doubts as to the existene of Troy

D) were doubtful concerning Troy's existence

E) had doubts about Troy's ever existing

不明白为什么E不对。have sb's doubt about sth (见LONGMAN） 时态上由BY引导用过去完成时态也可以啊。

Doubt的用法：

1.没有否定意义时，doubt后接 whether从句

2.有否定意义时，doubt后才接that,如：have no boubt that.

故我选C，不知对不对

同问，这里的existing不就是动名词么

总觉得a)应该说doubted whether Troy had ever existed

就是这么想的所以选了e

正因为是介词所以后面不能接动词。所以用ING的形式啊.

A 用动词doubt比E中的名词好.

E中的existing应该是exists, 因为about是介词.
