问题 The librarian requires that all books ______ returned before the last day of classes.

选项 A、are
B、be
C、must be
D、would be

答案 B

解析本题测试的是虚拟语气的用法。全句的意思是：“图书管理员要求在学期结束前归还所有的书。”在suggest，order，recommend，require，propose，request，decide， persist等表示命令、建议、请求的动词后面的宾语从句要用虚拟语气，宾语从句的谓语动词用“should+动词原形”结构，其中should可以省略。根据句意，应选答案B。
