---------leaves the room last ought to turn off the light.
a,anyone b,the person c,whoever d,who
解析,句意
答：C
译：最后离开这个房间的人应关灯.
析：本不想做这题的,因为太简单,大家都选对了.可看了宋ocean这个七级的回答,觉得有必要说几句.
本题考查名词性从句和定语从句.如果选AB,则后跟一个定语从句,从句中缺少了作主语用的关系代词who,所以排除.
CD都可以引导名词性从句.whoever=anyone who.,句子正确.
who也可以引导名词性从句,与what,when,why不同的是,它只能引导由疑问句变化而来的名词性从句：Who is to go abroad is a question.I don't know who is to go abroad.The question who is to go abroad is not clear.The question is who is to go abroad.
而What,when,where,why除了可引导由疑问句变来的名词性从句（有疑问性质）外,还可以引导没有疑问性质的名词性从句：
What you said is wrong.
This is where I was born.
That was when the war was happening.
That's why he was late.
四者均=the+名词+定语从句（分别由that,where,when,why 引导,名词分别为“事情”,“地点”,“时间”、和“理由”.最后一项的名词必为reason)
而要引导没有疑问性质的、表示“人”的名词性从句,只能用whoever,不能用who
本题句从谓语可知没有疑问性质,所以不能选D.
[quote] He laughs best who laughs last.
（笑到最后的人才笑得最好）如果用 He laughs best whoever laughs last.
（无论是谁,笑到最后才是笑得最好.）就显得格外啰嗦,就这句话本身而言,英语中也没有这种表达.补充原句理解是：who leaves the room last ought to turn off the light = those who leave the room last ought to turn off the light = a person who leaves the room last ought to turn off the light .[/quote]
第一句中的who 引导的是定语从句,先行词是who,被谓语laughs best 分隔开了,(因为不会引导歧义）,本来是：He who laughs last laughs best.
与what,when,where,why不同的是,whoever只能引导名词性从句,不能引导定语从句,但它却可以引导让步状语从句.（when,where,why可引导时间、地点、原因状语从句）
所以你第二句话中的whever 引导的是让步状语从句,=Whoever laughs last ,he laughs best.= No matter who laughs last,he laughs best.确实是不合逻辑的.
宋ocean最后的补充是错的,应是：whoever leaves .= Anyone who leaves...= Those who leave .=The person who leaves .,
PS:Mr.宋ocean给我发了个短信.他是一个认真的人,严谨的人,一个值得尊敬的朋友.
我也顺便再修改一下原贴中的两个错别字,再“住”你楼下吧.
