They demanded that the books________ to the school library at once. A．return B．should return C．be returned D．would be returned

Answer 1

C

试题分析：考查虚拟语气。表示命令、建议、要求等的词demand, command, order, request, require, suggest(建议)，insist(坚持要求)等，后面的宾语从句用虚拟语气，即，should+动词原形。should可省略。根据demanded可知，是过去时，排除A；根据（should）+do排除D；books 和return是动宾关系，用被动语态，排除B。故选C。
