DScientistshave discovered anew techniquebywhichlight canbe bent around corners,inspiredby theway clouds scatter（散射）sunlight.This type of light-bendingcould leadtoimprovements in many fields such as medicalimagingand electronics cooling.Daniele Faccio at the University of Glasgow,UK,and his workmates say they areshocked that thistype of lightscatteringwasn'tnoticedbefore.Itworks on the samebasisasclouds，snowandotherwhitematerialsthatabsorblight:oncephotons（光子）hitthesurface ofsuchamaterial,theyarescatteredin alldirections.“The light goes around and tries to get in,” says Faccio.“And eventually what happensis that it just gets reflected back because it can’tget in.This is this scattering.”Tocopythisprocess,theteam3Dprintedobjectsfromaspecialwhitematerialwhileleavingthintunnels（通路）within.Whenlightisshoneatthematerial，ittravelsintothesetunnels and is scattered—just as light is on snow or clouds.However,instead of scatteringrandomlyineverydirection,thephotonsaredirectedtoreturntothetunnelsbythematerial.The team put this touse,creatinga range of objects that control light in anorganisedway.Theresearcherssaytheirmaterialimproveslighttransmissionmuchbetterthanthosewithoutthesametunnels,andalsoallowsittobedirectedaroundcurves.This method of light-bending could make use of existing tunnels of some specialmaterialstoprovidenewwaystocarryoutmedicalimaging.Facciosaystheexactsamewayalsoworkstodirectheatandneutrons,andcouldthereforealsofinduseinarangeofengineeringapplicationssuchascoolingsystems.32.What inspired the discovery of the technique?A.Howlighttravels.B.HowcloudsscattersunlightC.Therelevant studies.D.Thefeatures ofwhite materials.33.According to paragraph 4,what is thekey to controlling thelight scattering？A.Themotionof thephotons.B.The size of thematerial.C.The tunnels inside the material.D.Theprocess of3Dprinting34.Whatdoesthelastparagraphmainlytalkabout？A.Future study in light-bending.B.Potential problems of medical imaging.C.Possible applications of this newtechnique.D.Experts’opinionsontheuseofspecialmaterials.35.Whatisthepurpose ofthetext?A.Tointroduceacreativetechnique.B.To sing high praise for innovative spirits.C.Toexplain theprincipleoflightscatteringD.Tohighlighttheadvantagesoftechnology英语试题第6页（共10页）
