问题 ______ leaves the room last ought to turn off the lights
选项 A、Anyone
B、The person
C、Whoever
D、Whom
答案C
解析 语法题，此题考查主语从句的用法。主语从句应用一连接词＼连接代词＼连接副词来引导。连接词在主语从句中不担任任何句子成分，仅起连接作用；连接代词除了引导从句外，还要在主语从句中担任主语＼宾语＼表语＼补足语成分；而连接副词则除了引导从句外，还要在主语从句中担任状语成分。此外，为使句子结构平稳，形式主语it也常常使用，而把真正的主语——主语从句挪到句子末尾去。本题是一含有主语从句的主从复合句，主语从句缺少主语，故需填入的应是一连接代词，又由于该连接代词还要担任主语从句的主语，因而必须是主格代词，综合考虑所有这些因素，只有C对。含有主语从句的主从复合句类例：it is still not known whether he will attend the meeting or not．(连接词引导，不担任主语从句的句子成分)It is known to us all that theory comes from practice．(连接词引导，不担任主语从句的句子成分)Which dictionary he will take with him has not been decided yet．(连接代词引导，且担任从句的句子成分——主语从句的主语的定语)What he will say at the meeting has not been made known．(连接代词引导，且担任从句的句子成分一一主语从句的宾语)When she will begin the experiment has not been made clear．(连接副词引导，且担任从句的句子成分一一主语从句的时间状语)
