题目内容
【题目】It is required in the library regulations that any book borrowed __________ by due time, or the borrower will be fined.
A. return B. be returned
C. returns D. is returned
【答案】B
【解析】试题分析:考虚拟语气的形式。此处虚拟语气形式为it is requiered + 动词原形,而书是被借,所以被动语态用be returned。句意:图书馆规章制度要求任何借出的书都要及时归还 ,否则借阅者要被罚款。故选B
