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 本文為一篇說明文，哈佛大學(xué)的一組技師在自然界的激發(fā)下，創(chuàng)造了第一部機(jī)器人蒼蠅．進(jìn)而描述了機(jī)器人蒼蠅的樣子與用途．本文以此展開，主要講述機(jī)器人蒼蠅的研發(fā)，面臨的困難以及前景．

解答 32．C．細(xì)節(jié)理解題．考生根據(jù)第二段最后一句"The added difficulty with a project like this is that…可知事實(shí)上那些元件沒有一件能現(xiàn)貨供應(yīng)的，要理解be off the shelf 的用法，所以選項(xiàng)C．they had no ready-made components就是對(duì)本句的同義替換，故為正確答案．根據(jù)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．根據(jù)文章第二段"It's extremely important for us to think about …，"the Harvard engineering professor who has been working …．可知選項(xiàng)B．they did not have sufficient time他們沒有充足的時(shí)間，不合適；而選項(xiàng)D．they could no assemble the components他們不會(huì)組裝元件是對(duì)原文的誤解，并不是要組裝，故排除選項(xiàng)D．故選C．
33．B．推理判斷題．題干要求在第三段和第四段來推測(cè)，所以根據(jù)文章內(nèi)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．故選項(xiàng)A．consists of a flight device and a control system是片面的，排除；根據(jù)第四段so that it might someday perform data-gathering work at rescue sites，in farmers'fields or on the battlefield．可知選項(xiàng)C．中的from many sources應(yīng)為 from many sites/places，故排除；選項(xiàng)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．可知已經(jīng)大量應(yīng)用是錯(cuò)誤的，故排除．縱觀三四兩段，尤其是第四段尾句"Basically it should be able to take off，land and fly around，"he said．可推斷出只有B．can just fly in limited areas at the present time正確．故選B．
34．D．推理判斷題．文章末段的to study biology in ways…would be difficult with animals，but using these robots instead告訴我們這些機(jī)器人可以替代動(dòng)物，故D項(xiàng)正確．考生注意的是，說明文末段尤其帶有轉(zhuǎn)折關(guān)系的路標(biāo)詞往往是題眼所在．根據(jù)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選項(xiàng)錯(cuò)誤，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．，并沒有說：不允許拿動(dòng)物進(jìn)行生物實(shí)驗(yàn)，故排除B選項(xiàng)．根據(jù)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．"可知以后會(huì)有更多的問題等待我們?nèi)ヌ剿鳎�但并不是說過去在研究昆蟲飛行方面常常方法很少，故排除．故選D．
75．C．主旨大意題．A選項(xiàng)意為"機(jī)器人蒼蠅之父"，文章的主題主要說明"機(jī)器人蒼蠅"，故排除．B選項(xiàng)"來自工程學(xué)中的靈感"與文章的主題"機(jī)器人蒼蠅"關(guān)系不大，故排除．D選項(xiàng)"哈福大學(xué)在昆蟲研究領(lǐng)域的突破"，并沒有點(diǎn)明主題"機(jī)器人蒼蠅"，故排除．C選項(xiàng)既交待了"Robotic Fly"又講了與真實(shí)生活中昆蟲的關(guān)系．故選C．

點(diǎn)評(píng) 本文是一篇科教類閱讀，題目涉及多道主旨大意題，細(xì)節(jié)理解題，推理判斷題．做題時(shí)學(xué)生應(yīng)仔細(xì)閱讀原文，把握文章主要內(nèi)容，聯(lián)系文章上下文內(nèi)容并結(jié)合所給選項(xiàng)含義，從中選出正確答案，一定要做到有理有據(jù)，切忌胡亂猜測(cè)．
