Several educational research groups are denouncing the mayor's proposal of a system by which individual teachers would be given raises or bonuses should it be that test scores show their students' mastery of reading skills having improved over a nine-month period.

A.should it be that test scores show their students' mastery of reading skills having  

B.should it be that test scores show their students' mastery of reading skills have  

C.should test scores showing their students' mastery of reading skills has  

D.if test scores showing their students' mastery of reading skills having  

E.if test scores show that their students' mastery of reading skills has  

这道题的答案是E
既然前面是would be given 说明这道题用的是虚拟语气，既然是虚拟语气，这里答案中的show应该是用过去式的吧。望拍砖。谢谢

这里并非虚拟语气，整句都不存在虚拟条件，ABC错，would是情态动词表目的或期望，D没有谓语动词

虚拟语气表示的是一种与事实相反的情况，这里确实没有这种语气，但是would做情态动词的时候是will的过去式，整句话中没有过去时的痕迹，这一点我觉得有点问题
