Certainly the mathematical notion of a fraction was known to the Babylonians, perhaps as early as 2000b.c. But our wordfraction goes back only to the Latin word frangere, "to break.” From the stem of the past participlefrāctus is derived Late Latin frāctiō, "a breaking" or "a breaking in pieces,”as in the breaking of the Eucharistic Host.In Medieval Latin the wordfrāctiō developed its mathematical sense, which was taken into Middle English along with the word.The earliest recorded sense of our word is "an aliquot part of a unit, a fraction or subdivision,”found in a work by Chaucer written about 1400.One of the next recorded instances of the word recalls its origins, referring to the "brekying or fraccioun" of a bone.人们也许认为一个词如fraction 以及它的词源总是指数学上的分数。 当然，分数的数学概念也许早在公元前 2000年就已被巴比伦人所熟知。 但fraction 一词仅能追溯到拉丁词 frangere ，“打碎”。 源自过去分词fractus 的词干是派生的后期拉丁语 fractio ， 意为“破裂”或“碎成一片片的”，如感恩节的饼的碎块。在中世纪拉丁语中，fractio 一词出现了数学意义， 这个词连同此意义都被记入中世纪英语中。这个词最早记载的意义是“一个数学单元，繁分数或再分数的约数”，出现在约1400年乔臾写的一部作品里。后来此词有记录的例子之一，指骨头上的“裂痕或碎片”，使人回忆起它的起源〔grade〕A mark indicating a student's level of accomplishment.成绩等级，分数：指示一个学生成绩水平的标记〔express〕express a fraction as a decimal.用小数来表示分数〔bowl〕To achieve (a specified score) by bowling.滚球得分：通过滚球得（一个特定分数）〔test〕To achieve a score or rating on tests:测得结果：在考试中获得一个分数或级别：〔nose〕predicted the final score on the nose.精确地预测了最后分数〔notch〕notched the score on a stick.在木棍上切出分数记号〔sweat〕sweat out one's final grades.焦急地等待最后的分数〔grade〕To give a grade to (a student, for example).评分：给分数（例如一个学生）〔point〕A numerical unit of academic achievement equal to a letter grade.分数：学业成绩的数字形式的单位，等于用字母表示的等级 |
