“all of”,“both of”和“neither of”的用法有什么区别?

先来一个总结,再给例子
either of (两者其一)
neither of(两者都不)
这两个后＋单数
both of (两者都),后＋复数
all of (三者或三者以上都是)
none of (三者或三者以上都不是)
例子
either of 是指“两者有其一.”
Either of us speaks English. （注意“speaks“）
neither of是指“两者都不...” 用于否定句
Neither of usEnglish. (注意“speaks“）
both of是指两者都. 用于肯定句
Both the boys are clever. 两个男孩都很聪明.
Either of与both of 注意区别两者的意思,不同的意思,单复数不一样.
① There are two apples on the table; you can take either of them. 桌上有两只苹果,随你拿哪一只.
② There are two apples on the table; you can take both of them. 桌上有两只苹果,你可以把两只都拿去. \x0b③ There are trees on either side of the street. 街的两边（每一边）绿树成荫.
④ There are trees on both sides of the street. 街的两边绿树成荫.
all of是指所有人（或物）都...（超过两个）
All of the Chinese students are Young Pioneers.所有中国学生都是少先队员.
否定式:Not all of,意思是“不全是” (千万不要误认为是“全部都不是”.)
Not all of us went to school yesterday.昨天我们不全都来上学.
对比:All of us went to school yesterday.昨天我们全都来上学.
none of 是指“所有人（或物）都不...”全部否定（超过三个）
以None of 开头的句子,谓语动词用单数或复数均可.
None of.作主语,强调个体时,谓语动词用单数；若强调整体时,谓语动词则用复数.
None of us speaks English. （注意“speaks“）
