anyone（或any one）是一个单词还是两个单词呢？答案取决于我们怎么去使用这个单词或短语。在这两个词之间加上空格，它的性质也就发生了变化。
不定代词anyone（一个词语）指的是所有的人都是如此，没有出现例外的个人。
any one（两个词）是一个形容词短语，指的是一个群体中的任意一个成员（可以是人，也可以是物）。any one通常后面会接上介词of。
A similar distinction applies to anybody and any body, nobody and no body.
anybody和any body，nobody和no body之间的区别也与这个类似。

Usage Note
用法提示
"What's the difference between anyone and any one? Or between everyone and every one? First, they are all grammatically singular, regardless of meaning. But there is a difference in meaning between the one- and two-word versions: when you type anyone or everyone, you're referring to people; when you type any one or every one you may be referring to people, but not necessarily--it depends on what follows or what is understood."
anyone和any one，或者说everyone和every one的区别在哪里呢？首先，把意义放在一边，从语法上讲它们都是单数，但是，一个词语和两个词语在意思上是存在差别的，当你输入anyone或everyone时，你指的是人；当你输入any one或every one时，你指的就不一定是人了。这取决于后面的词语或者人们的理解。
For example, perhaps you mean 'any one of the customers' or 'every one of the customers' (in which case you are referring to people); or maybe you mean 'any one of the petunias' or 'every one of the petunias' (in which case you are not referring to people). In sum, any one and every one mean one of a group (of people or things), rather than one person (anyone) or a bunch of people (everyone)."
例如，你想表达的是‘顾客中的任何一个’或者‘顾客中的每一个’（这种情况下你指的是人）；或者你想说‘喇叭花中的一朵’或‘每一朵喇叭花’（这种情况下你指的就不是人）。总而言之，any one和every one指的是一个群体（人或物）中的一个，而不是单独的一个人（anyone）或一群人（everyone）。
