模型上练习使用机器蛇，然后再将机器蛇用于猪身上进\o"行测"行测试，但并没有在这之后又用于人测试，而是一个位于波士顿名叫Medro-botics的公司把这项技术用于人的手术，所以题干中提到的Zenati把机器蛇用在人身上进行测试与文章本意不符。答案为B.22、C第七段只是提到Medrobotics公司目前把这项技术应用到人类手术中，但并没有提到因此给公司带来高额利润，所以题干中提到的信息在文中没有显示。答案为C.第3部分：概括大意与完成句子(第23-30题，每题1分，共8分)下面的短文后有2项测试任务：(1)第23~26题要求从所给的6个选项中为第1~4段每段选择1个最佳标题;(2)第27-30题要求从所给的6个选项中为每个句子确定1个最佳选项。BlackHoles1Blackholescanbebestdescribedasasortofvacuum,suckingupeverythinginspace.Scientistshavediscoveredthatblackholescomefromanexplosionofhugestars.Starsthatareneardeathcannolongerburnduetolossoffuel,andbecauseitstemperaturecannolongercontrolthegravitational(重力的)force,hydrogenendsupputtingpressureontothestar’ssurfaceuntilitsuddenlyexplodesthencollapses.2Blackholescomefromstarsthataremadeofhydrogen，othergasesandafewmetals.Whentheseexplodeitcanturnintoastellar-mass(恒星质量)blackhole,whichcanonlyoccurifthestarislargeenough(shouldbebiggerthanthesun)fortheexplosiontobreakitintopieces,andthegravitystartstocompacteverypieceintothetiniestparticle.Trytoseeandcompare;ifastarthat’stentimesthesizeofthesunendsupbeingablackholethat’snolongerthan70kilometers，thentheEarthwouldbecomeablackholethat'sonlyafractionofaninch!3Objectsthatgetsuckedinablackholewillalwaysremainthere，nevertobreakfree.Butrememberthatblackholescanonlygobbleup(吞噬)objectswithinaspecificdistancetoit.It’spossibleforalargestarnearthesuntobecomeablackhole，butthesunwillcontinuetostayinplace.Orbits(轨道)donotchangebecausethenewlyformedblackholecontainsexactlythesameamountofmassaswhenitwasastar,onlythistimeitsmassistotallycontractedthatitcanendupasnobiggerthanastate.4Sofar,astronomershavefiguredoutthatblackholesexistbecauseofAlbertEinstein’stheoryofrelativity.Intheend,throughnumerousstudies,theyhavediscoveredthatblackholestrulyexist.Sinceblackholestraplightanddonotgiveofflight,itisnearlyImpossibletodetectblackholesviaatelescope.Butastronomerscontinuetostudygalaxies(银河系),spaceandthesolarsystemtounderstandhowblackholesmightevolve.Itispossiblethatblackholescanexistformillionsofyears，andlatercontributetoabiggerprocessingalaxies,whichcaneventuallyleadtocreationofnewentities(实体).Scientistsalsocreditblackholesashelpfulinlearninghowgalaxiesbegantoform.23、Paragraph1
