anyone是代词，不是名词，不分单复数的。释义：(用于否定句、疑问句，也用于if或whether之后，或紧接prevent、forbid、avoid等动词，代替someone)任何人;随便哪个人;重要人物。
anyone的用法1、anyone指“任何人”，不指“任何一个”，any one指“任何一个”，但是有时也指“任何人”，现在比较不普遍那样说；
2、anyone不能同one或one's同时使用，如Ifanyonecomes, ask him to wait里面的him不可替换成one；
3、anyone后不可接动词的否定形式，所以不能说Anyone cannot do it，该说No one can do it。
