1.everyone等于everybody,意思是“每个人”,不指具体哪个人,而是强调整体。作主语时,一般与单数谓语动词连用,但在俗语中,谓语动词有时也用复数。
2.everyone也可泛指人。
3.当回指everyone时,常用they, them或their。
4.everyone和否定词not连用,表示部分否定。
5.everyone在反意疑问句中,如果含意相当于汉语的“人人”,表示集合的而不是个别的意味,附加疑问句的代词往往用they。

Everyone knows it.大家都知道这件事。
Everyone who had been in the neighborhood of the robbed orchard were questioned.被抢果园邻近居住的每一个人都被盘问了。
Everyone were questioned.大家都受审了。
Everyone had to empty their purposes.每个人都不得不说出他们的目的。
Everyone is not present.并非每个人都来了。
Everyone can't do it well, can they?谁也做不好,对吗?

everyone, every one
这两者的区别在于:
1.everyone后通常不接of引起的短语; every one常与of引起的短语连用,用以加强语气。
2.everyone只用于人; 而every one既可用于人也可用于物。
