Question

11．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，"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 is 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 night 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．"

32．The difficulty the team of engineers met with while making the robotic fly was thatC．
A．they had no model in their mind
 B．they did not have sufficient time
C．they had no ready-made components
D．they could not assemble the components
33．It can be inferred from paragraphs 3 and 4 that the robotic flyB．
A．consists of a flight device and a control system
 B．can just fly in limited areas at the present time
C．can collect information from many sources
D．has been put into wide application．
34．Which of the following can be learned from the passage？D
A．The robotic flyer is designed to learn about insects．
B．Animals are not allowed in biological experiments．
C．There used to be few ways to study how insects fly．
D．Wood's design can replace animals in some experiments．
35．Which of the following might be the best title of the passage？C
A．Father of Robotic Fly  
B．Inspiration from Engineering Science
C．Robotic Fly Imitates Real Life Insect 
D．Harvard Breaks Through in Insect Study．

Answer 1

分析 本文为一篇说明文，哈佛大学的一组技师在自然界的激发下，创造了第一部机器人苍蝇．进而描述了机器人苍蝇的样子与用途．本文以此展开，主要讲述机器人苍蝇的研发，面临的困难以及前景．

解答 32．C．细节理解题．考生根据第二段最后一句"The added difficulty with a project like this is that…可知事实上那些元件没有一件能现货供应的，要理解be off the shelf 的用法，所以选项C．they had no ready-made components就是对本句的同义替换，故为正确答案．根据文章第一段Designed to do what a fly does naturally，the tiny machine is the size of a fat housefly．是有制作模型的，故排除A．根据文章第二段"It's extremely important for us to think about …，"the Harvard engineering professor who has been working …．可知选项B．they did not have sufficient time他们没有充足的时间，不合适；而选项D．they could no assemble the components他们不会组装元件是对原文的误解，并不是要组装，故排除选项D．故选C．
33．B．推理判断题．题干要求在第三段和第四段来推测，所以根据文章内容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．故选项A．consists of a flight device and a control system是片面的，排除；根据第四段so that it might someday perform data-gathering work at rescue sites，in farmers'fields or on the battlefield．可知选项C．中的from many sources应为 from many sites/places，故排除；选项D．has been put into wide application的定位在第五段Yet，the power，sensing and computation technologies on board could have much broader applications．可知已经大量应用是错误的，故排除．纵观三四两段，尤其是第四段尾句"Basically it should be able to take off，land and fly around，"he said．可推断出只有B．can just fly in limited areas at the present time正确．故选B．
34．D．推理判断题．文章末段的to study biology in ways…would be difficult with animals，but using these robots instead告诉我们这些机器人可以替代动物，故D项正确．考生注意的是，说明文末段尤其带有转折关系的路标词往往是题眼所在．根据第四段so that it might someday perform data-gathering work at rescue sites，in farmers'fields or on the battlefield．可知A选项错误，故排除．文章最后一段中指出"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．，并没有说：不允许拿动物进行生物实验，故排除B选项．根据文章最后一段Wood says the design offers a new way to study flight mechanics and control at insect-scale．及"So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day-to-day basis．"可知以后会有更多的问题等待我们去探索，但并不是说过去在研究昆虫飞行方面常常方法很少，故排除．故选D．
75．C．主旨大意题．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．故选C．

点评 本文是一篇科教类阅读，题目涉及多道主旨大意题，细节理解题，推理判断题．做题时学生应仔细阅读原文，把握文章主要内容，联系文章上下文内容并结合所给选项含义，从中选出正确答案，一定要做到有理有据，切忌胡乱猜测．
