二者的区别在于意思不一样
who指谁,是特殊疑问词
例如：who are you?
whoever是“无论谁”,引导主语从句,有时也引导宾语从句,类似的有“which”与“whichever”
whoever (pron).谁
⑴连接代词,引导名词性从句(=anybody that)
Whoever comes will be welcome.谁来都欢迎.
Give it to whoever you like.你喜欢给谁就给谁.
⑵做疑问代词(比who语气重) Whoever said that?是谁讲的那话?
Whoever can that be knocking at the door?敲门的会是谁呢?conj.不管是谁(引导状语从句,=no matter who)
Whoever rings,tell him I'm out.不管谁来电话,告诉他我不在家.
例题:______ leaves the room last ought to turn off the lights.
A.Anyone B.The person C.Whoever D.Who
那D为什么不能选?
选C
whoever“无论谁”,可以引导主语从句,不能用anyone 引导从句.
whoever既是从句leave the room last 的主格,又是“ought to turn off the lights ”的主语
无论谁最后离开这间房都应该关灯.
