each VS every,everyone VS every one 英语运用究竟each 和 every 有什么不同?听说这两个词语在一些情况下不能使用,例子呢?everyone every one each one 有什么不同?最好附上解释/用法/例子,

each与every都有“每个”的意思,但二者含义及语法功能不同,主要区别是：
1.each既可用作形容词,又可用作代词,在句中可以作定语,主语、宾语、同位语、状语等.
Each studen t has his own dictionary .（形容词,定语）
Each has hi s good point .（代词,主语）
Our head teacher had a ta lk with each of us .（代词,宾语）
The students each h ave a desk .（代词,同位语）
The children can have a b ag each .（副词,状语）
2.each与every都可用作形容词,在句中作定语,但each更强调个人或个别,every更强调全体或全部.比较：
I know each number of your family .
I know every number of your f amily .
3.each指两个或两个以上的人或事物中的“每个”；every是指许多人或事物的“全体”,与all的意思相近.试译：来源：www.examda.com
