问题补充：

Every student as well as all the teachers required to be at the bus station at 6:30 tomorrow.

A. are

B. is

C. were

D. was

答案：

A. are

(答案→)B. is

C. were

D. was

解析：考查主谓一致。由 as well as, along with, with, together with, like, besides, in addition to，but连接两个名词作主语时，谓语动词和前面的名词保持一致。故要与student 保持一致，结合后面的时间状语at 6:30 tomorrow可知选B答案。句意：所有学生和老师都要求明天6:30赶到汽车站。
