1、3. each通常用来指若干固定数目中的每一个，而every往往指“任何一个”如：Each girl sitting over there is my student. “坐在那里的每一女孩子”指若干固定数目中的每一个，故用each。Every man must do his best. “人人都尽最大的努力”泛指任何一个人，因而用every。4. every和not连用，即“everynot”或“notevery”构成部分否定，表示“并非每一个”的意思，each则无此结构。5. every+ 基数词+ 复数名词=every+ 序数词+ 单数名词，作“每（多少）”解，但each不能用于这一结构
2、中。 如： every three days 每三天或每隔两天，相当于 every third day。6. every two days, every second day都作“每隔一天”解，但在实际应用中人们都用every other day来表示这一意思，every two days也有人讲，而every second day则少用的。7. 也可以说every few days, 相当于汉语的“隔些日子”。8. each 可以与other构成固定的搭配，即each other意思为“彼此、相互、互相”的意思，而every则不能。续.1. each既可用作形容词，又可用作代词，在句中可以作
3、定语，主语、宾语、同位语、状语等。例如：Each student has his own dictionary . （形容词，定语）每个学生都有自己的字典。Each has his good point . （代词，主语）各人有各自的优点。Our headteacher had a talk with each of us . （代词，宾语）我们的班主任与我们每个人都谈了话。The students each have a desk . （代词，同位语）学生们每人有一张书桌。The children can have a bag each . （副词，状语）孩子们每人可带一只提包。2. eac
4、h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 .我认识你们家的每个成员。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 are many shops on each side of the
5、 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。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 w
6、as busy with his work .正I saw everyone was busy with his work .5. 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。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。6. every可以与not连用构成部分否定，意思是“并不/非人人
7、”，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。人人都不喜欢这个电视剧。误Each / Everyone / Every one of them doesnt like the TV play .正No one likes the TV play .7. each与other可构成相互代词，every则不可以。We should take care of each other and help each other .我们应该互相关心，互相帮助。8. 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。Theyll choose one out of every ten girls .他们将在每十个姑娘里挑选一个。We hand in our homework every three days .我们每隔两天（每三天）交一次作业。注意：“每三天或每隔两天”，也可以写作“every third day”，即，若用序数词时，后接单数名词。再如every four weeks / fourth week（每四周/每隔三周），every other day / second day / two days（每隔一天），every other line（每隔一行）等。
