both neither either all none的用法 ①指两者“都”，表示肯定，后接复数名词，作主语时谓语动词用复数。反义词是neither 。例句：Both of the sisters are students. both ②构成搭配both.....and.....表示两者兼有。例句：Both Lucy and Lily are students . ①指两者中的“任何一个”，作主语时谓语动词用单数。例句：Either of the students is clever. Either of them likes football. either ②构成搭配either…or… 表两者中任意一者。意为"或者……或者……；不是……就是……"。表示两者之一。当连接两个主语时，谓语遵循就近原则。例:Either you or he is student. Either you or I am student. ①指两者“都不”，表示否定，作主语时谓语用单数。 例句：Neither of the students is clever. Neither of them likes football. ②构成搭配neither…nor… 表示两者都否定（既不…,也不…），当连接两个主语时，谓语应遵循就近原则。例如：Neither I nor she is at home. neither Neither she nor I am at home. all 指三者（或三者以上）“全部都”，表示肯定，后接可数名词复数（作主语时谓语动词用复数）和不可数名词（作主语时谓语动词用单数）。反义词是none。例：All of the students are in our class. 指三者（或三者以上）“都不，没有一个”，表示否定。作主语时谓语动词用单数或复数都可以。例：None of the students are/is in our class. none 注意：表示两者关系的用both, either或neither 表示三者或三者以上关系的用all 或none 区分下列句子： He has two sons. Both of them are clever. 他有两个儿子，都很聪明。 He has two sons. Either of them is clever. 他有两个儿子，哪个都很聪明。 He has two sons. Neither of them is clever. 他有两个儿子，两个都不聪明。 He has three sons. All of them are clever. 他有三个儿子，都很聪明。 He has three sons. Any of them is clever. 他有三个儿子，哪个都很聪明。 He has three sons. None of them are clever. 他有三个儿子，个个都不聪明。 注：以上连词连接主语时，both…and… 一般只与复数谓语连用，either…or…和neither…nor… 则通常根据就近原则，要求谓语动词与最邻近主语的人称、数保持一致。如： 1 Neither I nor she is at home. =Neither she nor I am at home. 我和她都不在家。 Either I or my brothers are coming. = Either my brothers nor I am coming.不是我父亲就是我兄弟要来。 若要对either...or...句型进行否定时，只需把either...or...换成 neither...nor...即可。例如： Either you or she is good at drawing. 变为否定句应为： Neither you nor she is good at drawing. 你和她都不擅长绘画。 若将neither...nor...句型变为肯定句，只需把neither...nor...改为both...and...即可，同时谓语动词必须用复数形式。例如： Neither dad nor mum is at home today. Both dad and mum are at home today. 今天父母都在家。 Exercises: 一、用正确的词填空。 1、He has two uncles ._______ of them are doctors. 2、-----Which do you prefer ,the red one or the blue one ? ----- _______ is OK.
