who care是who cares的错误表达，who cares的意思是：谁在乎呢。
care
英 [keə(r)] 美 [ker]
v. 关心；担忧；照顾；喜爱；介意；倾向于；愿望；在乎
n. 小心；照料；忧虑；注意；护理
who
当作疑问词来用时，就只能用单数形式。故
Who
cares?
是对的。这个who与定语从句中的
who不一样。定语从句中要看先行词的数来确定who之后谓语动词的数。
想告诉大家：不要说 Who care，要说:
因为 Who 在这里是泛指任何人，相当于 anyone，<span "="">意思是：谁会在乎呢? 既然是anyone，<span "="">所以就要是第三人称单数，要用 cares.
