Superhighways ofvessels(血管)beneath our skin transportblood andnutrients.Thesenatural pathways branch out liketree limbs tohelp our body movefood and oxygen to ourorgans.Our bodies make vessels naturally,butbioengineers also want to make them artificiallyAndnow ateam of engineershasfounda coolnewway to do that in thelab:Theyuse ice.Tomake the vessels,theengineers first needed a template(模板)fromwhich to buildthetissue.“Originally,we were trying to do thiswithwax(蜡),”saysOzdoganlar,a mechanicalengineer who’s leading the new vessel-building project atCarnegieMellonUniversity.But waxproved“toosoft,"hesays.“Andit'snotnecessarilybiocompatible(生物兼容的),"or suitablefor use in thebody.Then they thought ofElsa's magic in a DisneymovieFrozen.Ice seemed like a good alternative to wax.It costs little andis readily available.And sinceit's not poisonous,the body won’treject it.Andprinting the ice template is simple.First,engineersprogram its shape into a 3-Dprinter.The printer then drops water onto a very coldsurface.The printer repeats this process until the vessel's shape is complete. In all, it takes lessthan 30 seconds.This icy vesseltemplateis then encased in gelatin,a clear substance withoutany taste.Shining ultravioletlight on the gelatin hardens it as the ice melts away.What's left arerealistic-lookingchannels forbloodto movethroughSo far, the Carnegie Mellon team has testedthe gel channels with endothelial cells.Thesearethe cells that linethe inner walls of blood vessels.In one experiment, thosecells survivedbefore suchreplacement vessels could be transplanted intopeople.In the future, such artificial vesselscould beused aspart of lab-made organs to save thelives of people urgently awaiting donated organs.for transplant.“This is really a game changer,"saysOzdoganlar.32.What inspired the team ofengincers to useice instead?A.ThemovieFrozenB.Its lowcost.C.Thenewproject.D.Its easy availability.33.Whatdoesparagraph3mainly talk about?A.Thedifferencesbetween iceand wax.B.The reason for printing the ice template.C.The application of 3-D printing technologyD.The advantages ofice as vesselprinting stuff.34.Whatcan we infer from the last two paragraphs?A.Thelab canmass produce organs for use.B.The technology is not yet mature at this pointC.The artificial vessels will be put to use soon.D. The organ transplantation is easier to perform.35.What is the author's purpose in writing the text?A.To singhighpraise for engineers'work.B.To makeknown a technical innovationC.To promote vessels made by using ice.D.To encourage technological innovation.第二节(共5小题:每小题2.5分,满分12.5分)
