内容概述
阿基米德在《论球与柱》中证明:内接于半径 r、高 2r 的圆柱中的半径 r 的球,其体积和表面积都正好是外接圆柱的三分之二,他对此深感自豪并遗言在墓碑上刻一个内接于圆柱的球。马塞卢斯攻陷叙拉古后,怀着敬意厚葬了他并满足了这桩心愿。公元前 75 年,罗马检察官西塞罗到西西里巡视时发现叙拉古人早已忘了阿基米德墓,他费尽气力在 Achradmae 门内的荆棘丛中找到一根小石柱,上面仍刻着那个内接的球。西塞罗命人清理墓地、加固修葺;然而他的崇敬未能延续,今天阿基米德墓已荡然无存。
中文正文
79° 阿基米德之墓
阿基米德在他《论球与柱》中建立了我们今天计算球体体积和面积的公式。基本图形是内接在半径 r、高 2r 的正圆柱体中的半径 r 的球(图 9)。阿基米德证明,球的体积正好等于外接圆柱体积的三分之二,球的面积正好也等于圆柱表面积的三分之二。阿基米德当然为这些发现感到自豪,还立下一个遗愿,在他的墓碑上刻一个内接在圆柱里的球。当马塞卢斯怀着崇敬厚葬阿基米德时,特别吩咐要了却他的心愿。
多年以后,公元前 75 年,西塞罗(Cicero)到西西里做罗马检察官。他打听阿基米德的墓,可令他惊讶的是,叙拉古人一无所知,甚至说根本就没有什么墓。西塞罗费了很大气力,小心巡遍了 Achradmae 门的所有墓碑。最后,他找到一个小石柱,孤零零立在荆棘灌木丛中,上面刻着内接在圆柱里的球。于是,那位最伟大的叙拉古人的墓,在人们遗忘多年之后重现了。西塞罗让人用镰刀清除了墓地的杂草灌木,下令重修墓地,还原旧观。我们不知道西塞罗的崇敬延续了多久;今天,阿基米德墓已经荡然无存了。
英文正文
In his work On the Sphere and Cylinder, Archimedes established what are tantamount to our present-day formulas for the volume and the area of a sphere. The basic figure of the work is a sphere of radius r inscribed in a right circular cylinder of radius r and height 2r (see Figure 9). Archimedes showed that the volume of the sphere is exactly two thirds of the volume of the circumscribed cylinder, and the area of the sphere is exactly two thirds of the total area of the circumscribed cylinder. Archimedes was justly proud of these discoveries and expressed a wish that a figure showing a sphere with a circumscribed cylinder (like Figure 9) be engraved on his tombstone. When, with great honor and veneration, Marcellus buried the famous mathematician, he saw to it that Archimedes' request was carried out.
Many years later, in 75 b.c., when Cicero was serving as Roman quaestor in Sicily, he inquired as to the whereabouts of Archimedes' tomb. To his surprise, the Syracusans knew nothing of it and even denied that any such thing existed. With considerable effort and care he examined all the monuments at the Achradmae gate. Finally he noticed a small column, standing out a little above overgrown briars and shrubs, with the figure of a sphere and circumscribed cylinder upon it. Thus the long-neglected and forgotten tomb of the greatest of all Syracusans was rediscovered. Cicero had men with scythes clear the brush away, and then he left orders that the surrounding grounds be restored and preserved. How long this respect was kept up we do not know; today the tomb has completely vanished.

长难句解析
Archimedes was justly proud of these discoveries and expressed a wish that a figure showing a sphere with a circumscribed cylinder (like Figure 9) be engraved on his tombstone.
- 主干:Archimedes was proud and expressed a wish。
- 修饰与从句:that 引导同位语从句说明 wish 的内容;从句中 showing a sphere with a circumscribed cylinder 为现在分词短语修饰 figure;括号 like Figure 9 为插入说明。
- 逻辑关系:先说明阿基米德因发现而自豪,再引出他希望刻在墓碑上的具体图形。
语言使用特点
- 数学史叙事中常用被动与正式表达,如 was carried out、was rediscovered,以保持客观与庄重。
- 涉及度量的句子多用精确分数表达比例关系,如 two thirds of。
迁移练习
- 用英文写出球体积与圆柱体积的“三分之二”关系。
- 用 tantamount to 造一个关于“古代方法与现代公式”的句子。
- 将“他不知道阿基米德墓在哪里”改写成含有 inquire as to 的句子。
