一、分类识记

  都 都 任一(其中任何一个) 都不(一个也不)
两者 both either neither
多者 all any none


 二、用法说明1. 表示否定可说not…either / any，但没有either / any…not的说法。2. none可指人或物，一般要接表示范围的of短语，可回答how many / much；no one只能指人(=nobody)，不能接of短语，可回答who。3. both / all与not连用表示部分否定，意为“并非都”。4.  all单独使用或后接一个定语从句或前面有物主代词时，意为everything或the only thing(s)。
