8、 added difficulty with a project like this is that actually none of its components is off the shelf and so we have to develop them all on our own，” said Robert Wood，a Harvard engineering professor.They engineered a series of systems to start and drive the robotic fly.“The seemingly simple system whi
9、ch just moves the wings has lots of interdependence(互相依赖) of 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.While this first robotic flyer is linked to a small，offboard power source，the goal is eventu
10、ally to equip it with a builtin power source，so that it might someday perform datagathering 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

12、aid.“So there are a lot of technologies and open interesting scientific questions that are really what drives us on a daytoday basis.”【语篇解读】本文是一篇说明文。哈佛大学的工程师团队研制出了机器苍蝇飞行器，该飞行器虽然尺寸如苍蝇大小，但结构复杂，可望在未来执行搜救、农田勘探等领域的数据收集任务。1What is the typical characteristic of the robotic fly?AIts automatic.BIts very smal
13、l.CIts controllable.DIts quite powerful.B细节理解题。根据第一段第二、三句“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”可知，这种飞行器设计初衷是为了能做苍蝇做的事，它的尺寸和肥胖的家蝇一样大，微小的翅膀可以让它停在空中执行受控的飞行任务；据此可知，该飞行器的典型特点是
14、尺寸小，故B项正确。2We can infer from the passage that the robotic flyer can_.Aact as a spy planeBhelp do farm workCfly at a very high speedDanswer many scientific questionsA推理判断题。根据第四段第一句中的“so that it might someday perform datagathering work at rescue sites，in farmers fields or on the battlefield”可知，某一天这种飞行
15、器可能用于搜救点、农田、战场信息的收集；据此可推知，该飞行器可以用作间谍飞机，故A项正确。3What is Woods idea about the robotic fly according to the last paragraph?AIt is highly questionable.BIt has wide practical applications.CIt gives scientists interest in flying machines.DIt points to a new direction in studying biology.B细节理解题。根据尾段第二句“Yet，the power .could have much broader applications”并结合Wood所说的话可知，Wood认为这种飞行器使用范围很广泛，故B项正确。4What can be the best title for the passage?AHarvards Study in the Field of InsectsBA Breakthrough in Engineering ScienceCAn Interesting InventionRobotic FlyDRobotic Flya Copy of the Real Life
