【解析】这是一篇说明文。文章介绍了 3 月 14 日是圆周率日（Pi Day），这个节日是为了纪念数学中著名的常量圆周率。
1．考查宾语从句。句意：3 月 14 日看似平常，但数学学习者知道那意味着什么。knw后接宾语从句，从句中缺少宾语，意为“什么”，用what引导宾语从句。故填what。
2．考查非谓语动词。句意：圆周率π，等于圆的周长除以圆的直径。句中已有谓语动词is，空处用非谓语动词后置定语修饰逻辑the circumference f a circle和divide是被动关系，应用过去分词。故填 divided。
3．考查名词复数。句意：对于所有大小的圆，从硬币到披萨再到行星，情况都是如此。根据“f all sizes” 可知，此处指各种圆，应用 circle 的复数形式 circles。故填circles。
4．考查时态和语态。句意：这就是为什么圆周率日在 3 月 14 日被庆祝。句子描述客观事实，用一般现在时，Pi Day 与 celebrate 是被动关系，应用一般现在时的被动语态，主语 Pi Day 是单数，be 动词用 is。故填is celebrated。
5．考查副词。句意：但圆周率的精确值实际上是不可能完整写出来的。修饰形容词 impssible，应用副词 actually，意为 “实际上”。故填actually。
6．考查形容词。句意：去年，一台强大的计算机将圆周率计算到了创纪录的 62.8 万亿位。修饰名词 cmputer，应用形容词 pwerful，意为“强大的”。故填 pwerful。
7．考查冠词。句意：然而，没有人能算到圆周率的尽头。the end f... 表示“…… 的尽头”，为固定搭配。故填the。
8．考查时态。句意：历史学家不确定人们何时首次发现圆周率的概念。空处为从句谓语动词，根据“first” 及语境可知，动作发生在过去，应用一般过去时，discver 的过去式为 discvered。故填discvered
9．考查介词。句意：但它以某种形式存在了近 4000 年。“fr + 时间段” 表示动作持续的时间。故填fr。
10．考查非谓语动词。句意：埃及人可能用圆周率来建造金字塔。此处表目的，应用动词不定式作目的状语。故填t build。
