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
答案选E。
如果选E的话难道不应该是the teachers would be given bonus if test scores showed that their student...？
因为would，所以我的理解只if引导的从句也应该用过去式。。。
WILL的话，if引导的从句才是一般现在式，
难道我理解错了？
