中考英语语法学习专辑---数词

补充：every和each的区别：

　　1. each可作代词和形容词，而every只能用作形容词，如可以说each of these dictionaries或each one of these dictionaries, 但不能说every of these dictionaries, 该用every one of these dictionaries。

　　2. each可指两个或两个以上中间的每一个，而every只可指三个或三个以上中间的每一个，不能指两个中每一个。如： 可以说each of my eyes, 不可说every one of my eye但可说every one of my toes(脚趾) 。

　　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.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。
