  相关英文原文阅读Biomimetic Design

  What has fins like a whale, skin like a lizard, and eyes like a moth? The future of engineering. Andrew Parker; an evolutionary biologist, knelt in the baking red sand of the Australian outback just south of Alice Springs and eased the right hind leg of a thorny devil into a dish of water.

  “Its back is completely drenched!” Sure enough, after 30 seconds, water from the dish had wicked up the lizard’s leg and was glistening all over its prickly hide. In a few seconds more the water reached its mouth, and the lizard began to smack its jaws with evident satisfaction. It was, in essence, drinking through its foot. Given more time, the thorny devil can perform this same conjuring trick on a patch of damp sand---a vital competitive advantage in the desert. Parker had come here to discover precisely how it does this, not from purely biological interest, but with a concrete purpose in mind: to make a thorny-devil-inspired device that will help people collect lifesaving water in the desert. “The water’s spreading out incredibly fast!” he said, as drops from his eyedropper fell onto the lizard’s back and vanished, like magic. “Its skin is far more hydrophobic than I thought. There may well be hidden capillaries, channeling the water into the mouth.”

  B Parker’s work is only a small part of an increasingly vigorous, global biomimetics movement. Engineers in Bath, England, and West Chester, Pennsylvania, are pondering the bumps on the leading edges of humpback whale flukes to learn how to make airplane wings for more agile flight. In Berlin, Germany, the fingerlike primary feathers of raptors are inspiring engineers to develop wings that change shape aloft to reduce drag and increase fuel efficiency. Architects in Zimbabwe are studying how termites regulate temperature, humidity, and airflow in their mounds in order to build more comfortable buildings, while Japanese medical researchers are reducing the pain of an injection by using hypodermic needles edged with tiny serrations, like those on a mosquito’s proboscis, minimizing nerve stimulation.

  C Ronald Fearing, a professor of electrical engineering at the University of California, Berkeley, has taken on one of the biggest challenges of all: to create a miniature robotic fly that is swift, small, and maneuverable enough for use in surveillance or search-and-rescue operations. Fearing made his own, one of which he held up with tweezers for me to see, a gossamer wand some 11 millimeters long and not much thicker than a cat’s whisker. Fearing has been forced to manufacture many of the other minute components of his fly in the same way, using a micromachining laser and a rapid prototyping system that allows him to design his minuscule parts in a computer, automatically cut and cure them overnight, and assemble them by hand the next day under a microscope.

  题型难度分析本篇文章属于常见的科技类文章,此类文章与我们生活联系少,因此阅读和做题过程中较难利用常识猜测文义以及选项,也容易被不熟悉的词汇误导,考生应对文章结构进行整体把握。另外,本文题型主要为匹配题,难度较大。题型技巧分析信息匹配题是雅思阅读各类题目中难度最大的题目之一,这类题目往往以“Which paragraph contains the following information?”为标志,考查考生查找信息以及理解文章的能力。

  题型特点:1. 绝对乱序 2. 考察细节信息以及同义转换 3. 种类繁多 4. 部分题目有重复选项

  解题步骤:

  1.审题并阅读所有题目

  2.画出题目关键词并做出预判

  3.通读段落,依次寻找答案

  *人名匹配题小技巧:人名之后出现插入语代表人名是第一次出现;人名多次出现后,姓和名可能分开,也可能用代词指代。
