everyone加be动词is还是are?everybody呢?something呢?everything呢?还有everywhere和somewhere

都和单数谓语连用（如 is,was)
everywhere,somewhere 是副词,与“数”无关他们用they we代替还是用单三代替口语中如果用人称代词来代的话， everyone, everybody 等一般用they
someone, somebody 一般用he能造一个句子吗Everyone is here, aren't they? 大家都到了， 是吗？

Someone is absent, isn't he? 有人缺席， 是吗？
