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 student has his own dictionary . （形容词，定语）

Each has hi s good point . （代词，主语）

Our head teacher had a talk with each of us . （代词，宾语）

The students each have a desk . （代词，同位语）

The children can have a bag 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 family .

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：

这条街上每边都有很多商店。

［误］There are many shops on every side of the street .

［正］There a re many shops on each side of the street .

我给她父母每人 一件礼物。

［误］I gave a present to every one of her parents .

［正］I gave a present to each of her parents .

4.指上下文提到过的确定数目中的“每一个”时，要用each；如果上下文没有提及时，不能用each，要用everyone等。试译：

我认为这三个答案个个都正确。

［误］I think every answer of the three is right .

［正］I think each of the three answers is right .

我看见人人都忙着工作。

［误］I saw each was busy with his work .

［正］I saw everyone was busy with his work .
