both, all, neither, none, either, every的用法

我们汉语中说“每一。。。" "都” “一个也没有”时是没有数的区别的，也就是说无论谈论的数是多少，这几个汉字都是一样的。但是英语不同，表达这几个意思的单词有数的区别，谈论二者和三个以上的东西时所用的词是不一样的，利用下图把这几个词一次性记住就不会困惑了。下图中“(=2)”表示谈论的事物为2者时，“＞＝－3”表示谈论的事物为三者或三者以上时。

如果上图还没看明白，再看下面的文字说明：

当我们谈论的事物为两者中的“每一。。。”时用either。

当我们谈论的事物为三者或以上的“每一。。。”时用every。

当我们谈论两者“都”时用both。

当我们谈论三者或以上“都”时用all。

当我们谈论的事物为两者中“一个也没有”时用neither(=no+either)。

当我们谈论的事物为三者或以上“一个也没有”时用none(=no +one)。

另外，二者以上的都可以用each，也就是说each包含了either和every的用法。
