主旨题。该段录音首先指出科学家们担心手机的使用会影响人类的健康，因为研究表明手机辐射会加速癌细胞数量的增长。接着录音中提到虽然无法从研究结果得出辐射会对人类健康带来直接威胁的结论，但证明了一些科学家认为辐射会损害DNA并摧毁细胞修复系统的观点。录音最后描述了世界卫生组织和英国政府对手机使用持有戒备态度，敦促人们减少使用。由此可知，录音的主要内容是关于手机会给人类带来的潜在危险。因此选项D为正确答案。

答案：D
解析：
结构题。文章最后一段围绕苏格拉底的the good展开，倒数第二段强调苏格拉底的dialectic，即“辩证法”，分别介绍苏格拉底哲学的不同精髓。故D项“讨论与第四段平行的另一个方面”为正确答案。故本题选D。参考译文：苏格拉底是雕刻家索福罗尼库斯的儿子，是希腊雅典的哲学家。据说，苏格拉底在早年时从事过父亲的工作，中年时，他娶了传说中的泼妇克桑西普，但这些故事几乎没有确凿的事实依据。我们尚不确定苏格拉底的哲学老师是谁，但他似乎熟悉巴门尼德、赫拉克利特、阿纳萨戈尔和原子论者的学说。甚至苏格拉底在40岁之前就因其智力而广为人知，根据柏拉图在《道歉》中对苏格拉底演讲的描述，特尔斐的神谕称他是希腊最聪明的人。在那次演讲中，苏格拉底坚称，他对这种称呼感到困惑。尽管其他人没有意识到自己在无知的情况下宣称自己有学问，苏格拉底至少意识到了自己的无知。苏格拉底确信，自己的使命是寻找引导正确行为的智慧，以此来促进雅典人在智力和道德方面的进步。苏格拉底忽略了自己的事务，把时间花在讨论美德、正义和虔诚上，而不管他的同胞们在何处聚集。有些人认为他也忽视了公共职责，因为他从来没有寻求过公共职位，尽管他以在他从事的军事战役中所表现出的勇气而闻名。在他自封为“牛虻”的任务中，苏格拉底树敌众多。阿里斯托芬在他的戏剧《云》中嘲弄了苏格拉底，并认为他身上有诡辩家(修辞的专业教师)的一些缺点。尽管苏格拉底的确激怒过诡辩家，但其他批评者似乎与阿里斯托芬持相似的观点。公元前399年，他因荼毒青年和宗教异端而受到审判。围绕审判的是模糊的政治问题，但苏格拉底似乎也因为是阿尔基比阿德斯和克里蒂亚斯的朋友和老师而受到审判，原因是这两个人都背叛了雅典。柏拉图的《道歉》《克里托》和《法耶多》以巨大的戏剧性力量描述了苏格拉底的审判和死亡。苏格拉底对哲学的贡献包括一种理解知识的新方法，一种将灵魂视为集正常清醒意识和道德品质于一体的概念，以及一种有目的地按头脑顺序排列的宇宙意识。他的方法被称为辩证法，包括通过探究陈述的含义来检验陈述，假设一个陈述是真实的，它不会导致错误的结果。这种方法可能是由芝诺(埃利亚)提出的，但苏格拉底对其进行了改进，并应用于伦理问题。苏格拉底的灵魂学说使他相信所有的美德都会汇聚成一种美德，这是真实自我的本质，并贯穿于人的一生。反之，知识取决于事物的本质，因为事物的潜在形式比它们的经验范例更为真实。这个概念导致了一种目的论的世界观，即所有的形式都参与并导致最高的善，或至善的理念。柏拉图后来阐明了这一学说是他哲学思想的核心。苏格拉底的观点经常被描述为认为美德和知识是相同的，所以没有人会故意犯错。因为美德与知识是相同的，所以它可以被教授，但不能像诡辩家把它作为一门专业那样教授。然而，苏格拉底本人并没有给出如何学习美德的最终答案。
