题目内容

Class regulations require _____ is the last to leave the classroom _____ off all the lights.

A. who; should turn                B. whom; shall turn

C. whomever; turns                D. whoever; turn

D


解析:

考查名词从句的连词和虚拟语气用法。主语从句中缺少主语,故用whoever=the person who, require后接宾语从句,句中动词用(should)do。
