A、team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech integrated systems.Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.“It’s extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components (元件),” said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade.
A、few years ago, his team got the go-ahead to start piecing together the components. “The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own,” he saiD、They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it’s connected to,” said WooD、The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactureD、While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers’ fields or on the battlefielD、“Basically it should be able to take off, land and fly around,” he saiD、Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. “You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead,” he saiD、“So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day to day basis.”(392 words) Which of the following might be the best title of the passage
A、Father of Robotic Fly
B．Inspiration fromEngineering Science
C．Robotic Fly Imitates Real Life Insect
D．HarvardBreaks Through in Insect Study

主旨大意题。本题考查考生理解全文、提炼信息、概括总结的能力。选择最佳标题，一般来说，考生只有通篇理解文章传递的信息，才可能概括出全文的最佳标题。对比四个选项，A选项意为“机器人苍蝇之父”，文章的主题主要说明“机器人苍蝇”，故排除。B选项“来自工程学中的灵感”与文章的主题“机器人苍蝇”关系不大，故排除。D选项“哈福大学在昆虫研究领域的突破”， 并没有点明主题“机器人苍蝇”，故排除。C选项既交待了“Robotic Fly” 又讲了与真实生活中昆虫的关系，所以争取答案为C。 document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
