长期的天文观测和研究,创立了更为科学的宇宙结构体系日心说,从此否定了在西方统治达一千多年的地心说。,日心说经历了艰苦的斗争后,才为人们所接受,这是天文学上一次伟大的革命,不仅引起了人类宇宙观的重大革新,而且从根本上动摇了欧洲中世纪宗教神学的理论支柱。“从此自然科学便开始从神学中解放出来”,“科学的发展从此便大踏步前进”（恩格斯自然辩证法）。,哥白尼著有阐述日心说的天体运行论(1543年出版),由于受到时代的局限,在日心说中保留了所谓“完美的”圆形轨道等论点。其后开普勒建立行星运动三定律,牛顿发现万有引力定律，以及行星光行差、视差相继发现,日心说遂建立在更加稳固的科学基础上。,weknowthefirstscientistiscopernicus.hewasoneofthefirstscientiststousemathematicalobservationstocollectinformation.hebelievedthesunisthecenteroftheuniverseandtheearthandotherplanetswentaroundit.thechartonp.7showshistheory.,copernicusrevolutionarytheory,birth:february19,1473death:may24,1543placeofbirth:toru,polandcareer:1491-1494studiedmathematicsatkrakwacademy1496wenttoitalytostudyastronomyandlawattheuniversityofbologna,nicolascopernicus,1497beganobservationsofthesun,moon,andplanets1514wrotecommentariolus,anoutlineofhisastronomicalideas,butdidnotcirculateitwidely1543publishedderevolutionibusorbiumcoelestium(ontherevolutionsofthecelestial),atcopernicustime,christianchurchwasinchargeofmanywesterncountries.,readthroughthepassage,andtellwhetherthefollowingstatementsaretrueorfalse.,3.copernicusdidntshowhisnewtheorytohisfriendsuntilhecompletedit.4.hisfriendswerenotinterestedinhisideas.,2.copernicusnoticedthatobservedfromtheearth,someplanetsappearinfrontoforbehindtheearth.,5.sincehewasnotafraidofbeingattackedbythechurch,copernicuspublishedhisbookassoonashefinishedworkingonit.6.newton,einstein,andhawkingareallscientistswhomadecontributionstothestudyoftheuniverse.,adiagramshowingthesolarsystemwiththeearthatitscentre,adiagramshowingthesolarsystemwiththesunasitscentre,readcarefullyandtrytodrawthetwotheoriesoftheuniverse.,1.whatconclusiondidcopernicusmathematicalcalculationsleadto?2.whycouldnthetellanyoneaboutthetheory?3.howmanyyearsdidcopernicusworkontheproblemtocompletehistheory?4.whendidcopernicuspublishhistheory?5.doyouthinkitsrightforcopernicustopublishhistheorythatlate?,readthetextandanswerthefollowingquestions.,hismathematicalcalculationsledtotheconclusionthattheearthwasnotthecenterofthesolarsystem.,whatconclusiondidcopernicusmathematicalcalculationsleadto?,becausethepowerfulchristianchurchwouldhavepunishedhimforevensuggestingsuchanidea.,2.whycouldnthetellanyoneaboutthetheory?,4years.,3.howmanyyearsdidcopernicusworkontheproblemtocompletehistheory?,studentsgivetheirownanswers.,5.doyouthinkitsrightforcopernicustopublishhistheorythatlate?,hepublishedhistheoryashelaydyingin1543.,4.whendidcopernicuspublishhistheory?,2ifyouwerenicolauscopernicus,wouldyouhavehiddenyourtheoryforsomanyyears?giveyourreasons.,asascientist,copernicuswasmorecautiousthancoward.ifhehadpublishedhisideasathistime,hewouldhavebeenkilledjustasbrunowhowasburnttodeathbecausehistheorywasagainstthechristianchurchs.everytimeanewideaappears,therearealwaysrejections.itsnormal.scientistsshouldhavepatiencetospreadtheirtruth.,1)这个句子，好像一点也讲不通。thesentencedoesntseemtomakesense.2)你编的故事我听不明白。yourstorydoesntmakesensetome.,1makesense讲得通；有道理,2enthusiastic:beinterestedin热情的;热心的shesvery_singing.weexplainourplan,andheisvery_.,enthusiasticabout/over,enthusiastic,enthusiasticenthusiasmenthusiastically,sheshowsboundless_forthework.shegreetedhim_withakiss.sheisvery_abouteasternmusic.,enthusiasm,enthusiastically,enthusiastic,ifyoudontliketom,youmayr_hisgift.ifyoudontthinkthesuggestionissuitableforyou,youmayr_it.,eject,eject,3rejectvt.拒绝;不接受;丢弃,herejectedtheirofferofajob.,他拒绝了他们给他的工作。,reject,anofferapossibilityatheory,refusetoaccept,rejected,candidateapplicant,theguardwarnedmetobecautiousaboutstrangers.,myfatherisaverycautiousdriver.,警卫告戒我要当心陌生人。,我的爸爸是一位非常谨慎的司机。,4cautious:carefultoavoidriskbecautiousabout/ofsb./sth.,firstinpairsbrainstormsomereasonswhyheshouldpublishhistheory.,nowwriteashortletteraskingcopernicustopublishhisideassoeveryonecanreadthem.,writing,secondmakeaplan.forexamplebeg
