”【语篇概括】本文介绍了“RoboticFly
”,
它能像真的苍蝇同样自然飞翔
,
小小的翅膀能让它停在空中,表演各样飞翔任务。B.aslargeasafathouseflyC.smallerthanafathouseflyD.aslargeasabutterfly【分析】选B。细节理解题。依据第一段的thetinymachineisthesizeofafathousefly.可知B正确。2.ItcanbeinferredfromParagraphs3and4thattheroboticfly__________.A.consistsofaflightdeviceandacontrolsystemB.canjustflyinlimitedareasatthepresenttimeC.cancollectinformationfrommanysourcesD.hasbeenputintowideapplication【分析】选B。推理判断题。题干要求从第三段和第四段推测,因此依据文章内容“butthenhastobematchedwelltoeverythingit’sconnectedto,”saidWood.Theflightdevicewasbuiltintoasetofpower,computation,sensingandcontrolsystems.应选项A.consistsofaflightdeviceandacontrolsystem是片面的,清除;依据第四段sothatitmightsomedayperformdata-gatheringworkatrescuesites,infarmers’fieldsoronthebattlefield.可知选项C中的frommanysources应为frommanysites/places,故清除;选项D.hasbeenputintowideapplication的定位在第五段Yet,thepower,sensingandcomputationtechnologiesonboardcouldhavemuchbroaderapplications.可知已经大批应用是错误的,故清除。纵观三、四两段,特别是第四段尾句“Basicallyitshouldbeabletotakeoff,landandflyaround,”hesaid.可推测出只有B.canjustflyinlimitedareasatthepresenttime正确。3.Whichofthefollowingcanbelearnedfromthepassage?A.Theroboticflyisdesignedtolearnaboutinsects.B.Animalsarenotallowedinbiologicalexperiments.C.Thereusedtobefewwaystostudyhowinsectsfly.D.Wood’sdesigncanreplaceanimalsinsomeexperiments.【分析】选D。推理判断题。文章末段的
to

in
waysthat
wouldbedifficultwithanimals,butusingtheserobotsinstead
告诉我们这些机器人能够代替动物
,
故D正确。考生需注意的是,说明文末段特别带有转折关系的词常常是题眼所在。依据第四段sothatitmightsomedayperformdata-gatheringworkatrescuesites,infarmers’fieldsoronthebattlefield.可知A错误,故清除。文章最后一段中指出“Youcanstartthinkingaboutusingthemtoansweropenscientificquestions,youknow,tostudybiologyinwaysthatwouldbedifficultwithanimals,butusingtheserobotsinstead,”hesaid.并无说:不同意拿动物进行生物实验,故清除B选项。依据文章最后一段Woodsaysthedesignoffersanewwaytostudyflightmechanicsandcontrolatinsect-scale.及“Sotherearealotoftechnologiesandopeninterestingscientificquestionsthatarereallywhatdrivesusonaday-to-daybasis.”可知此后会有更多的问题等候我们去探究,但其实不是说过去在研究昆虫飞翔方面经常方法很少,故清除C项。Whichofthefollowingmightbethebesttitleofthepassage?A.FatherofRoboticFlyD.Harvard’sBreakthroughinInsectStudy【分析】选C。要旨粗心题。此题考察考生理解全文、提炼信息、归纳总结的能力。选择最佳标题,一般来说,考生只有通篇理解文章传达的信息,才可能归纳出文章的最正确标题。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
,
故清除。
D选项“哈佛大学在昆虫研究领域的打破”
,
并无点明主题“机器人苍蝇”
,故清除。
C选项既交待了“
RoboticFly
”又讲了与真切生活中昆虫的关系
,
因此正确答案为
C。Ⅱ.
