多數(shù)詞典（如《牛津》《麥克米倫》）都提及，any表示不確切的少量時，主要用于否定句和疑問句，此時后接不可數(shù)名詞或復(fù)數(shù)名詞。表示三個或以上的總體中的任一個時，用于陳述句，后接單數(shù)名詞。但以下二個句子均為詞典例句，均為陳述句，為什么其中一個為any +復(fù)數(shù)名詞呢？

Any teacher will tell you that students learn at different rates. 任何老師都知道學生學習有快有慢。

Any girls who want to leave may do so.

首先我們看一下《韋氏詞典》對any的注釋之一。

any : one, some, or all indiscriminately of whatever quantity:

a : one or more —used to indicate an undetermined number or amount 

• Do you have any money?

b : all —used to indicate a maximum or whole 

• He needs any help he can get.

該詞典認為，any表示量的意義時，可以是一個、一些或全部。紅色部分為全部意義的解釋和例句。注意例句中的any help后接限制性定語。

結(jié)合《韋氏詞典》和其它詞典的解釋，我們可以推知，在陳述句中any后接名詞時，如果這個名詞沒有限制性定語，則該名詞為類指用法，即any表示該名詞所代表的人或事物中的任何一個。此時該名詞需用單數(shù)形式（any+單數(shù)名詞表示類指）。如果該名詞后接限制性定語，則該名詞為泛指用法。此時，該名詞可以用單數(shù)，也可以用復(fù)數(shù)（即被限制性定語所限制的這個范圍內(nèi)的人或事物的任一個、一些或全部）

現(xiàn)在看網(wǎng)友的兩個句子。teacher后沒有限制性定語，any teacher為類指用法。此時不可用復(fù)數(shù)any teachers。girls后接限制性定語從句，any girls who為泛指用法，指特定范圍內(nèi)的一個、一些或全部，此時也可以用單數(shù)any girl who. 仍為泛指用法。例如：

Any girl who wants to leave may do so.
