The university regulations require that the students?at least 90

The university regulations require that the students?at least 90%of the lectures．
A、Attended
B、to attend
C、would attend
D、attend
【正确答案】：D
【题目解析】：【考情点拨】考查require的用法。 【应试指导】句意：大学的规定要求学生至少要参加90％的课程。require表示“要求”，后面接that从句时谓语动词要用虚拟语气，结构为“should+动词原形”，should可以省略，故选D。
