21.6Listen carefullytothe footsteps in the familyhome,especially ifit haswoodenfloors,and youcan probablywork outwhoit is thatis walkingabout.The featuresmostcommonly usedto identifypeople arefaces,voices,finger printsand retinalscans.Buttheir^behavioural biometrics5\such asthe waythey walk,are alsogiveaways.Researchers have,for severalyears,used videocameras andcomputers to analysepeoples gaits,and arenow quitegood atit.But translatingsuch knowledgeinto apracticalidentification systemcan betricky——especially ifthat systemis supposedto behidden.Cameras areoften visible,are hard to setup,requi5re good lighting andmay havetheir viewblockedby otherpeople.So ateam ledby KrikorOzanyan of the University of Manchester,in Englandand PatriciaScully of the NationalUniversityofIreland,in Galwayhave beenlookingfor abetter wayto recognizegait.Their answer:pressure-sensitive mats.In themselves,such matsare nothingnew.They havebeen part of securitysystems fordonkeys5years.But Dr.Ozanyan AndDr.Scully usea complexversion thatcan recordtheamount ofpressure appliedin di^erent placesas someonewalks acrossit.Thesemeasurements forma patternunique tothe walker.Dr.Ozanyan and Dr.Scully thereforeturned,as isnow commonfor anythingto dowith patternrecognition,to anArtificialIntelligence systemthat usesmachine learningto recognizesuch patterns.It seemsto work.In astudy publishedearlier thisyear thetwo researcherstested theirsystemon adatabase offootsteps troddenby127different people.They foundthat itserrorrate inidentifying whowas whowasamere

0.7%.And DnScully saysthat evenwithout a•一database offootsteps to work withthe systemcan determinesomeones sexwomen and（骨盆）men,with wideand narrowpelvises respectively,walk indifferent ways,——andguess,with reasonableaccuracy,a subjectsage.A mat-based gait-recognition systemhas theadvantage thatit wouldwork in any-一lighting conditions-even pitch-darkness.And thoughit mightfail toidentify someoneif,say,shewas wearing stilettosand hadbeen enteredinto the database whilewearing trainers,itwouldbe veryhardtofool itby imitatingthe gaitof anindividual whowas allowedadmissionto aparticular place.The latestphase ofDr.Ozanyan^andDr.Scullys projectis aredesign ofthe mat.（光The oldmats containedindividual pressuresensors.The newones containoptical fibres纤）.（二极管）Light-emitting diodesdistributed alongtwo neighbouringedges ofa mat（transmit lightinto the fibres.Sensors onthe oppositeedges andthus theopposite endsofthe）optical fibresmeasure howmuch ofthat lightis received.Any pressureapplied topartof（变形）the matcauses adistortion in thefibresandaconsequent changein theamount oflighttransmitted.Both thelocation andamount ofchange can be plottedand analyzedby themachine-learning system.Dr.Ozanyan saysthattheteam havebuilt ademonstration fibre-optic mat,two meters（）long anda metrewide,using materialsthat cost£100$

130.They arenow talkingtocompanies aboutcommercializing it.One applicationmight bein healthcare,particularlyfor theelderly.A fibre-optic matinstalled ina nursinghome oran oldpersons ownresidencecould monitorchanges inan individuaPsgait thatwarn certainillnesses.That wouldprovideearly warningof someonebeing atgreater riskof fallingover,say,orof their cognitionbecomingdamaged.Gait analysismight alsobe usedass asecurity measurein theworkplace,monitoringaccess torestricted areas,such asparts ofmilitary bases,server farmsor laboratoriesdealingwith harmfulmaterials.In thesecases,employees wouldneed to agree totheir gaitsbeingscanned,just asthey wouldagree tothe scanningof theirfaces orretinas foroptical securitysystems.Perhaps the most fascinatinguse ofgait-recognition mats,though,wouldbein publicplaces,such asairports.For thatto work,thefootstepsof thoseto berecognized wouldneedto havebeen storedinadatabase,which wouldbe harder to arrangethan thecollection ofmugshotsand fingerprintsthat existingairport securitysystems relyon.Some people,however,might volunteerfor itMany aircrewor pre-registered frequentflyers wouldwelcomeanything thatspeeded up oneofthe mosttiresome partsof moderntravel.l^Camera-based gaitrecognition failsto comeinto wideuse,because・a.its noteasy tofindthe camerasb.finger printrecognition isstill popularc.sometimes thecameras can be coveredd・its awasteof moneyto fixthe equipmente.goodlightingconditions cantbe guaranteedf.its difficultto setup thesystem.A.acf B.bdeC.cdf D.cef、2Which ofthefollowingstatements isTRUE accordingto Paragraph6-8A.The newmats functiongreatly withindividual pressuresensors builtin.B.The newmats willbe likelytoworkbetter withenough pressure.C・The elderlyare curedoftheirdiseases withthe monitorofthefibre-optic.D.Restricted areasare accessibleto thosewith theirgaits scannedbeforehand.、3What does“it”refer toin Paragraph5A.The mat-based gait-recognition systemB.The gaitstoredin thedatabaseC.Theadvantage ofworking inany lightcondition.D.The admissionto aparticular place.、4Whaf sthe besttitle ofthe passageA.Listen toyour footstepsB.Applaud patternrecognitionC.Love theway youwalk D.Better themats youstep on（分）

1994.Her stylewas verysimple.Her blacktrousers,crisp whiteshirt andhair stylewas copiedby womenin theworld.Influencing fashiontrends canoften beabout timing.The movieMemoirs ofaGeisha camejust intime tostart atrend inJapanese fashion.It startedthe Chinese actressZhang Ziyi,who worebeautiful silkkimonos（和月艮），andit wonan Oscarfor CostumeDesign.Many travelcompanies pickeduponthetrendand ran“geisha trips”to Japan.Thefilm hasalso ledto aregained interestin kimonos.It isnow quitecommon tosee youngJapanesewomen wearingkimonos notjust ontraditional occasions,but atvarious socialevents.The fashionis alsobeginningtospread towestern countries.1What madethe authorthink aboutthe relationshipbetween moviesand fashiontrendsA.TheWildOne show.B.Influence ofthe filmBreakfastat Tiffanys.C.Marlon Brandosetting thetrend.D.His daughterswords.、2Who willpeople associateMadonna wearingthe leathermotorcyclejacketwithA.Marlon Brando.B.AudreyHepburn,C.UmaThurman.D.Zhang Ziyi.、3What isimplied in thefilmBreakfast inTiffanys accordingtothe passageA.One can be activeby wearingblack.B.One canbe stylishby eatingatTiffanys.C.One canbe famousby lookingperfect.D.One canbe elegantby wearingsimply.、4What doesthefilmMemoirs ofa Geishalead toA.The recoveryof interestin kimonos.B.The worldwidereading ofGeisha stories.C.The popularityoftheChineseactress.D.The“geisha trips”to socialevents.23・（8分）Dry Iceisaunique substancewhich hasmany uses.Essentially,dry iceisfrozen CO

2.The firstreport ofwhatwenow calldry icecame fromthe FrenchchemistCharles Thilorierin

1834.In324,the DryleeCorporation ofAmerica namedthe solidform ofCO2as Dry Ice”,which iswhat it is popularlycalled today.At normalatmospheric pressure,CO2changes directlyfrom solid to gas.It skipsthe（阶段）liquid phasewhich makesregular icewet.Frozen CO2is also much colderthanregular ice.But regularice freezesat32degrees Fahrenheit,CO2changes fromgasto solidat-

21.3degrees Fahrenheit.This extremelycold temperaturemakes itverydangerous tohandle withbare hands.It cancause frostbiteinavery shortperiod oftime.Dry icehas beenused fora varietyof purposesthroughout thepast century.Its primaryuseis torefrigerate foodwhen electricalrefrigeration isntavailable.Through theprocess of（）sublimation whenCO2changes fromsolidtogas,it canmaintain coldfood fora longtime.If youveever beentoaplay andseen heavyfog onthe ground,it islikely thatyou haveseendry icein action.This effectcanbeachieved becauseCO2is heavierthan air,so（挥发的）evaporated CO2will sinkand accumulateontheground.（诱杀）Another interestinguse forthis substanceis tobait insectslike mosquitoes.These insectshave sensorswhich guidethem toCO

2.They findthe highconcentration ofCO2in dry ice quiteattractive.Mars haslong beena mysteryfor humanbeings.We havebeen lookingfor evidenceoflife on Mars.In the360s scientistsguessed thatthe polarice capof Marswas madeof frozenCO
