Unit3Backtothepast古罗马帝国不仅仅在政治上强大,版图上辽阔,在哲学、文学、建筑等方面它所创造的古罗马文化,也是全人类巨大的精神财富和世界古典文化中的瑰宝。然而,你知道它是怎样瓦解的吗?Scientificassumption:therealcauseoftheRomanEmpirecollapsingClimatechangecouldhavebeenresponsibleforbringingdowntheRomanEmpire,scientistsbelieve.Researchersstudiedancienttreegrowthringstoshowlinksbetweenclimatechangeandmajoreventsinhumanhistorysuchasmigrations,plaguesandtheriseandfallofempires.Theydiscoveredthatperiodsofwarm,wetweathercoincidedwithperiodsofprosperity,whiledroughtsorvaryingconditionsoccurredattimesofpoliticalupheavalsuchasthedemiseoftheRomanEmpire.Tomatchtheenvironmentalrecordwiththehistoricalone,researcherslookedatmorethan7,200treefossilsfromthepast2,500years.Thestudy,publishedinthejournalScience,said:Theriseandfallofpastcivilizationshavebeenassociatedwithenvironmentalchange,mainlyduetoeffectsonwatersupplyandagriculturalproductivity,humanhealthandcivilconflict.WetandwarmsummersoccurredduringperiodsofRomanandMedievalprosperity.IncreasedclimatevariabilityfromAD250to600coincidedwiththedemiseoftheWesternRomanEmpireandtheturmoiloftheMigrationPeriod.[阅读障碍词]1.assumption假设,假定2.collapse崩溃,瓦解3.migration迁移,移居4.coincidedwith与……相一致5.prosperity繁荣,昌盛6.fossil化石[诱思导读]根据短文内容,回答下列问题1.What'stherealcauseoftheRomanEmpirecollapsingaccordingtoscientists?______________________________________________Climatechange.2.Whyistheriseandfallofempiresassociatedwithenvironmentalchange?__________________________________________________________________________________________________________________________________________Becauseitaffectswatersupplyandagriculturalproductivity,humanhealthandcivilconflict.SectionⅠReading(Ⅰ)(Welcometotheunit&Reading)新生词汇初识Ⅰ.匹配下列单词的词性及汉语意思()1.civilizationA.vt.兴建,创建()2.foundB.vt.&vi.逃避,逃跑;迅速离开()3.pourC.vt.毁坏,摧毁()4.decorateD.vt.装饰,装潢()5.disasterE.n.废墟;毁坏vt.破坏,毁灭()6.destroyF.vi.涌流,倾泻vt.倒出(液体)()7.commercialG.n.灾难()8.ruinH.n.文明()9.fleeI.adj.商业的,贸易的()10.remainsJ.n.遗物,遗迹,遗骸[答案]1-5HAFDG6-10CIEBJⅡ.选择下列句中词组的汉语意思A.保护……免受……B.消减C.和……一起D.出故障E.结果F.活埋1.Hetriedtocutdownonsmokingbutfailed.____2.Theycouldnothaveforeseenhowthingswouldturnout.____3.Hewasburiedaliveintheearthquake.____4.Hesenthersomerosestogetherwithaloveletter.____5.Themothertriedtoprotectherbabyfromeverydanger.____6.Themachinebrokedownatthebusytime.____[答案]1-6BEFCAD教材语篇细研LostcivilizationsDay1,15JulyIfeelluckytohavewonaplaceonthistrip.WeareinItalynow,andtomorrowwearevisitingPompeii.NextweekweareflyingtoChina,andgoingtoLoulan,①whichisknownasChina'sPompeiiinthedesert.BothPompeiiandLoulanbecamelostcivilizationslongago.Day2,16JulyThismorningweattendedalecture(讲座)aboutPompeii.Thecitywasfoundedinthe8thcenturyBC.In89BC,theRomanstookover(夺取)Pompeii.Itthenbecamearichandbusycity.②Nearthecitywasavolcano(火山).On24AugustAD79,thevolcanoerupted(爆发)andlava,ash(灰烬)androckspouredoutofitontothesurroundingcountryside.Itcontinuedtoeruptforthenexttwodays.Manypeoplewereburiedalive,and③sowasthecity.Howunfortunate(不幸的)!失落的文明第一天,7月15日能获得这次旅行的机会我感到幸运。现在我们在意大利,明天我们将游览庞贝。下周我们会飞往中国并打算去楼兰,那是沙漠中的一座被誉为“中国庞贝”的古城。庞贝和楼兰都是很久以前失落的文明。第二天,7月16日今天上午我们听了一场有关庞贝的讲座。这座城市兴建于公元前8世纪。公元前89年,罗马人占领了庞贝。后来庞贝成了一座繁华的城市。离该城不远处有一座火山。公元79年8月24日,这座火山爆发了,岩浆、火山灰以及岩石喷涌而出,全部倾泻到周围的村庄。火山喷发持续了两天。很多人被活埋了,整个城市也被掩埋。真是太不幸了![助读讲解]①whichisknownas...是非限制性定语从句,修饰Loulan。②表示地点的介词短语置于句首,且句子的主语是名词时,句子用全部倒装语序。③sowasthecity是倒装语序,意为“这座城市也如此”。Day3,17JulyTodayIsawtheancientRomancityofPompeii④asitwas2,000yearsago.Howamazing!Thecitywasforgottenformanyyearsuntilthe18thcentury⑤whenafarmerdiscoveredastonewithwritingonit.Peoplestartedtodigintheareafortreasure,⑥whichcausedmuchdamage.Thus,in1860,theareawasputundergovernmentprotection⑦soitcouldbepreservedandstudied.第三天,7月17日今天我见到了罗马古城庞贝,它就跟两千年前一模一样。多么令人惊奇啊!这座城市多年来一直被人们遗忘,直到18世纪时一个农民发现了一块刻有文字的石头。人们开始在这一区域挖掘寻宝,这造成了很大的破坏。因此在1860年,政府将这一区域保护了起来,便于保存和研究。[助读讲解]④asitwas2,000yearsago中as用作连词,意为“正如”,引导方式状语从句。⑤whenafarmerdiscovered...是定语从句,修饰the18thcentury,when相当于inwhich。⑥whichcausedmuchdamage是非限制性定语从句,修饰整个主句。⑦soitcouldbepreservedandstudied是目的状语从句。本句中so相当于sothat(为了,以便)。WhenIwalkedaroundthecity,Isawstreetsjust⑧astheyhadbeen,withsteppingstonesalongtheroadsoyoudidnothavetostepinthemud(泥浆)onrainydays!Isawseveralhouses⑨whichweredecoratedwithwallpaintings.Ialsosawthepeoplewhohadbeenburiedalive.⑩Itturnsoutthataftertheashcoveredthepeoplewhofailedtofleethecity,theirbodiesnearlycompletelybrokedownanddisappeared,leavingemptyspacesintheash.Yearslater,researchers(研究者)wereabletousetheseemptyspacestoproducetruetolifefiguresofthepeoplewhohaddiedinthedisaster.YoucanseethemtodayinPompeii,inthesameplaceswherethepeoplefell.Thevolcanoisstillthere,butlooksveryquietnow.It'shardtoimagine⑪howthispeacefulvolcanodestroyedthewholecity!当我在城中漫步时,我看到保持原样的街道,沿路都有垫脚石,这样下雨天你就不用在泥泞中行走了!我看见了几处装饰着壁画的房子。我也看见了被活埋的人。原来,火山灰覆盖了没能逃离城市的人,他们的身体几乎全部烧化消失了,只留下火山灰里的人形空当。多年之后,研究者们能够利用这些人形空当制作出逼真的遇难者轮廓。你现在可以在庞贝看到他们,就在原来他们倒下的同样的位置。火山还在那里,但现在看起来非常平静。很难想象如此平静的火山如何摧毁了整座城市![助读讲解]⑧astheyhadbeen是方式状语从句。withsteppingstones...是with复合结构(with+宾语+介词短语),作状语,修饰hadbeen。⑨which引导定语从句,修饰houses。⑩that从句为表语从句。在表语从句中after引导时间状语从句。在after引导的时间状语从句中who引导定语从句修饰先行词thepeople。leavin
