完美WORD格式 指三者（或三者以上）“都不，没有一个”，表示否定。作主语时none 谓语动词用单数或复数都可以。例：None of the students are/is in our class. 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：
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.
