nobody和everybody为什么都用is修饰

为什么nobody和everybody的Be动词都是is? nobody is happy 和 everybody is unhappy 的区别 Everybody's friend is nobody's Everybody's business is nobody's business. 请问nobody is everybody 是什么中文意思? 用everybody,somebody,anybody,nobody填空 Everybody is a friend to nobody 讲下, everybody's business is nobody's business谚语是什么意思? “Everybody's business is nobody's business "翻译 十万火急 everybody's work is nobody's work 是什么意思 a friend to everybody is a friend to nobody Everybody's friend is nobody's意思 阅读里答案选项是Not to be everybody
