关于each 和 every

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：
一、
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.例如：
1.Each student has his own dictionary .（形容词,定语）
2.Each has his good point .（代词,主语）
3.Our headteacher had a talk with each of us .（代词,宾语）
4.The students each have a desk .（代词,同位语,不影响谓语动词的单复数）
5.The children can have a bag each .（副词,状语）
二.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 member of your family .
我认识你们家的每个成员.
I know every member of your family .
我认识你们家的每个成员.
三.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 are 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 .
四.each 单独作主语或each、every修饰的单数名词作主语时,谓语动词为单数形式,但each of them作主语时,谓语动词用单数或复数形式都可以.例如：
Each / Each person / Every person is living a happy life now .
人人都过着幸福生活.
Each of them are / is wearing full dress .
他们个个都身着盛装.
五.every可以与not连用构成部分否定,意思是“并不/非人人”,而each则不可以与not连用.全部否定是no one ,意思是“个个都不”、“没有人”等.例如：
Each / Everyone / Every one of them doesn’t like the TV play .并非人人都喜欢电视剧 部分否定
No one likes the TV play .完全否定
六.表示“每隔……”、“每……”,要用“every＋基数词＋复数名词”.这种结构中的every不能用each替代.例如：
They’ll choose one out of every ten girls .
We hand in our homework every three days .
