anyone是代詞，不是名詞，不分單復(fù)數(shù)的。釋義：(用于否定句、疑問句，也用于if或whether之后，或緊接prevent、forbid、avoid等動詞，代替someone)任何人;隨便哪個人;重要人物。

1、anyone指“任何人”，不指“任何一個”，any one指“任何一個”，但是有時也指“任何人”，現(xiàn)在比較不普遍那樣說；

2、anyone不能同one或one's同時使用，如Ifanyonecomes, ask him to wait里面的him不可替換成one；

3、anyone后不可接動詞的否定形式，所以不能說Anyone cannot do it，該說No one can do it。
