10、ocolate milk,but pink silkworms（蚕）do produce pink silk,a team ofscientists has discovered.To see if they could produce pre-dyed silk-silk that comes color1 ed,straight from thesource-the team fed ordinary silkworms mulberry（桑树）leaves that had been sprayed（喷洒）with fabric（织物）dyes（染色剂）.Out of seven tes

11、ted dyes,only one worked,producing a thread that reminded me of pink-dyedhair.And yes,the worms themselves take on some color1 before they produce silk.Their color1 ful diets did notaffect their growth,the team,which included engineers and biologists from the CSIR-National ChemicalLaboratory in Indi

12、a,reports in the journalACS Sustainable Chemistry&Engineering.(The researchers didnt looktoo deeply into how the dyes affected the silkworms health.After all,silkworms die when people harvest theirsilk.)The team made dyeing silk this way because color1 ing fabric normally uses large amounts of fresh

13、 water.Thewater gets polluted with dangerous chemicals in the process,requiring costly treatment before factories can sendit back into waterways.Dyeing silk directly by feeding silkworms would avoid those water-washing steps.Scientistsare just starting to study this idea.However,it remains to be see

14、n if its commercially successful.In thisexperiment,the Indian team tested seven dyes,which are cheap and popular in the industry.The scientists found different dyes moved through silkworms bodies differently.Some never made it into theworms silk at all.Others color1 ed the worms and their silk but t

15、he color1 disappears before the silk is turned intofabric.Only one dye,named direct acid fast red,showed up in the final,washed silk threads.By the time it madeit there,it was a pleasant,light pink.4.The text is most probably a(n)_.A.science reportB.tourist guideC.animal experimentD.fashion advertis

18、hed to the pendulum,so the pendulum swings side to side as you walk.Then a machine is driven bythat swinging movement,and spits out electrical current to charge a battery.Volunteers carried the pack while walking on a running machine and wore masks to measure the flow ofO2and CO2.Walking with the sl

19、ightly swinging 20-pound load,the device(设备)did not significantly affect thevolunteers metabolic(新陈代谢的)rate compared to when they carried the same weight fixed in place.In fact,the energy-harvesting pack reduced the forces of acceleration theyd feel in a regular pack,which might meangreater comfort

20、for a long hike.And the device did produce a steady trickle(涓流)of electricity.If you up the loadto 45 pounds,the swing of the pack could fully charge a smart phone only after 12 hours.The details are in thejournal Royal Society Open Science.The device produces electricity from human movement and has

21、 been identified as a workable solution toproviding a renewable energy source for portable electronic devices.It is particularly useful for those who work inremote areas,as these people often carry a lot of weight in a backpack for their exploration.But heres a realconundrum:the energy-harvesting de
