原文重现：
The Sonar and Radar pioneers didn’t know it then, but all the world now knows that bats, or rather natural selection working on bats, had perfected the system tens of millions of years earlier, and their radar achieves feats of detection and navigation that would strike an engineer dumb with admiration. It is technically incorrect to talk about bat ‘radar’, since they do not use radio waves. It is sonar. But the underlying mathematical theories are very similar, and much of our scientific understanding of the details of what bats are doing has come from applying radar theory to them. The American zoologist Donald Griffin, who was largely responsible for the discovery of sonar in bats, coined the term 'echolocation' to cover both sonar and radar, whether used by animals or by human instruments.
原文翻译：
声纳和雷达的先驱者们当时并不知道，但是现在全世界都知道的是，蝙蝠，或者说作用于蝙蝠身上的自然的选择，使得它们身上这种系统在数百万年前就无比完美。它们的“雷达”系统在侦测和导航方面所取得的成就足以让一位工程师瞠目结舌、啧啧称赞。其实将其称为“雷达”是不正确的，因为他们并不使用无线电波。那是声纳。两者潜在的数学原理是相似的，而我们有关此方面的理解主要是来源于对雷达的应用。美动物学Donald Griffin发现了蝙蝠身上的声纳系统并先提出了“回声定位”这个术语以覆盖声纳和雷达，既指动物也指人类仪器。
原文逻辑结构分析：
此段是典型的议论文写作思路：提出论点--详细说明--举例说明。句The Sonar and Radar pioneers didn’t know it then, but all the world now knows that bats, or rather natural selection working on bats, had perfected the system tens of millions of years earlier.即提出论点，认为“声纳和雷达的先驱者们当时并不知道，但是现在全世界都知道的是，蝙蝠，或者说作用于蝙蝠身上的自然的选择，使得它们身上这种系统在数百万年前就无比完美。”二句则提出与雷达相似但又不一样的另一个新系统“声纳”。后一句列举美动物学的定义尾呼应。
美文赏析：
该段中写作为精彩的当属句话“The Sonar and Radar pioneers didn’t know it then, but all the world now knows that bats, or rather natural selection working on bats, had perfected the system tens of millions of years earlier, and their radar achieves feats of detection and navigation that would strike an engineer dumb with admiration.”主要有三点精彩之处：其一，比喻出彩。这里的“The Sonar and Radar pioneers didn’t know it then”（声纳和雷达的先驱们）其实指代蝙蝠，将其比喻为声纳和雷达的先驱者们，体现出英文中对人物指代的多样性特点。其二，用语出彩。“their radar achieves feats of detection and navigation that would strike an engineer dumb with admiration”一句中巧妙使用了strike someone dumb with admiration搭配，意为“将某人震惊到瞠目结舌、啧啧称赞”，画龙点睛、微言大义，不动声色之中将大自然赠与蝙蝠的特异功能赞美于笔下。其三，用词出彩。文中后一句“The American zoologist Donald Griffin coined the term 'echolocation' to cover both sonar and radar”，巧妙使用了coin和term两词的熟词僻意，分别意为“次提出”和“专业术语”，将本文的学术性展露无遗。
