Bionics: where nature and technology intersect Humans are curious by nature, and about nature. △Perfected over billions of years,nature’s forms and functions have inspired us to imitate it and develop materials and technologies that improve our lives. Consequently, a science known as “bionics” was born. 人类天生充满好奇心，对大自然（更是）充满好奇心。经过几十亿年的日臻完善，大自然的形态和功能激励我们去模仿它，开发出改善我们生活的材料和技术。因此，一门称之为“仿生学”的科学诞生了。 na·ture / ne t (r)/ 天性;本性;性格;自然界;大自然 per·fect /p fekt/ vt. 使完善；使完美；使完备 Although the term “bionics” officially dates back to 1958, the practice is centuries old. It could be said that as far back as 2,500 years ago, Lu Ban, a carpenter in ancient China, was engaged in bionics when he produced a saw by copying the shape of a leaf’s sharp teeth. Currently, bionics has scientists eagerly combing the natural world for original ideas to stimulate their creativity.据说早在 2500 年前，古代中国的木匠鲁班就开始从事仿生学，当时他通过模仿树叶锋利的齿状制造了一把锯子。目前，仿生学促使科学家热切地在自然界中寻找有创意的想法，激发他们的创造力。 have sb. doing sth. 使作出(某种反应) comb (through) sth (for sb/sth)仔细搜索；搜寻 The idea of taking inspiration from nature may sound simple; however, scientists often need to go to great lengths to effectively combine nature and innovation. Firstly, they must observe a living organism with the potential for offering solutions to a particular human problem. 从大自然中汲取灵感的想法可能听起来很简单；然而，科学家经常需要不遗余力地将自然和创新有效地结合起来。首先，他们必须观察有可能为某一特定人类问题提供解决方案的生物。 ta ... ...
