8、e the first robotic fly. The mechanical fly has become a platform for a series of new hightech 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.“Its extremely i
9、mportant 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 goahead to start piecing toget
10、her 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
11、 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 its connected to.” said Wood. The flight device was built into a set of power，computation, sensing and control systems. Wood says t
12、he 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, offboard power source, the goal is eventually to equip it with a builtin power source, so that it might someday perform datagathering w
13、ork 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 insectscale. Yet, the power, sensing and computation technologies on board could have much
14、 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 tha
15、t are really what drive us on a day to day basis.”语篇解读本文主要讲述哈佛大学从自然界的昆虫那里得到了灵感，设计开发了第一款机器苍蝇。文章介绍了该项研究存在的困难，研究将要发展的方向和该研究会带来的好处。1The difficulty the team of engineers met with while making the robotic fly was that _.Athey had no model in their mindBthey did not have enough timeCthey had no readymade componentsDthey could not assemble the components解析：C细节理解题。根据第二段可知类似这样的项目的一个额外的困难就是，这些组成部件从来就没有现成的，不得不靠自己去开发，可知困难就是没有现成的组成部件。2It can be inferred from Paragraphs 3 and 4 that the robotic fly _.Aconsists of a flight device and a control systemBcan just fly in limited areas at the pre
