32.ThehistoryofresponsestotheworkoftheartistSandroBotticelli(1444-1510)suggeststhatwidespreadappreciationbycriticsisarelativelyrecentphenomenon.Writingin1550,VasariexpressedanuneasewithBotticelli'swork,admittingthattheartistfittedawkwardlyintohisevolutionaryschemeofthehistoryofart.Overthenexttwocenturies,academicarthistoriansdefamedBotticelliinfavorofhisfellowsFlorentine.Michelangelo.Evenwhenanti-academicarthistoriansoftheearlynineteenthcenturyrejectedmanyofthestandardsofevaluationadoptedbytheirpredecessors,Botticelli'workremainedoutsideofacceptedtaste,pleasingneitheramateurobserversnorconnoisseurs.(Manyofhisbestpaintings,however,remainedhiddenawayinobscurechurchesandprivatehomes.)

TheprimaryreasonforBotticelli'sunpopularityisnotdifficulttounderstand：mostobservers,upuntilthemid-nineteenthcentury,didnotconsiderhimtobenoteworthy,becausehiswork,forthemostpart.didnotseemtotheseobserverstoexhibitthetraditionalcharacteristicsofthefifteenth-centuryFlorentineart.Forexample.Botticellirarelyemployedthetechniqueofstrictperspectiveand,unlikeMichelangelo,neverusedchiaroscuro.

AnotherreasonforBotticelli'sunpopularitymayhavebeenthathisattitudetowardthestyle.ofclassicalartwasverydifferentfromthatofhiscontemporaries.Althoughhewasthoroughlyexposedtoclassicalart.heshowedlittleinterestinborrowingfromtheclassicalstyle.Indeed,itisparadoxicalthatapainteroflarge-scaleclassicalsubjectsadoptedastyle.thatwasonlyslightlysimilartothatofclassicalart.

Inanycase,whenviewersbegantoexaminemorecloselytherelationshipofBotticelli'sworktothetraditionofthefifteenthcenturyFlorentineart,hisreputationbegantogrow.AnalysesandassessmentsofBotticellimadebetween1850and1870bytheartistsofthePre-Raphaelitemovement,aswellasbythewriterPater(althoughhe.unfortunately,basedhisassessmentonanincorrectanalysisofBotticelli'spersonality),inspiredanewappreciationofBotticellithroughouttheEnglish-speakingworld.YetBotticelli'swork,especiallytheSistinefrescoes.didnotgenerateworldwideattentionuntilitwasfinallysubjectedto4comprehensiveandscrupulousanalysisbyHomein1908.Homerightlydemonstratedthatthefrescoessharedimportantfeatureswithpaintingsbyotherfifteenth-centuryFlorentines—featuressuchasskillfulrepresentationofanatomicalproportions,andofthehumanfigureinmotion.However,HomearguedthatBotticellididnottreatthesequalitiesasendsinthemselves—rather.thatheemphasizedcleardepletionofastory,auniqueachievementandonethatmadethetraditionalFlorentinequalities1esscentral.BecauseofHome'semphasiscrucialtoanystudyofart,thetwentiethcenturyhascometoappreciateBotticelli'sachievements.

10.B

11.C

12.B

13.B

14.One

15.B

16.andand解析：“both…and…”为固定搭配，“两者都”。所以此处应填“and”。

17.dodo解析：分析见上题。故答案为do。

18.dumpingdumping解析：由本句句意“通过将污水和化学物质…人河流和湖泊，…”可知，此空处显然应为“倒”。又因为介词后只能用dumping，而不能用dump。

19.customercustomer解析：从这个句子的宾语“…thatheorshehasdoneagoodjobofchoosingtheitems．”可以看出，这里说的是顾客的行为，他们认为自己买这些商品是很理性的。故答案为customer。

20.someonesomeone解析：由本文的第一句话“‘Down-to-earth’meanssomeoneorsomethingthatishonest．realisticandeasytodealwith．”可知“Down-to-earth”指的是诚实，现实、平易近人的那些人。这里的someone和后面是相对应的。故答案为someone。

21.farfar解析：能修饰too的副词只有far或much。

22.atat解析：此题考固定搭配，atone'sdisposal，意为“任某人自由支配、使唤”。所以此处应填介词“at”。

23.onon解析：focuson意为“集中于”，为固定短语。

24.dodo解析：答案为do。

25.onon解析：此题也考查介词的用法，在电话中交谈，一般用onthephone。所以此处应填介词“on”。

26.C解析：由C中的howitworks中的第二条“Thismeansyoudon'tneedtousesomuchgasorelectricitytoheatyourwaterathome.”可知答案为C。

27.D解析：第二段第一句提到“…butoldwastefulhabitsdiehard”，可知虽然美国人开始回收利用一些物品，但是那种浪费的旧习惯依然不好消除。最后一句话“…itcanbecomestrongeronlyasAmericansseetheneedforitmoreclearly．”也说明了只有当美国人真正意识到环保的重要性，他们才能更好的具有环保意识，言外之意就是说他们依然没有完全意识到环保的重要性。故应选D。

28.C解析：由C中的第一段“Themonastery-likepalace…wasthereligiousandpoliticalcenterofoldTibetandthewinterpalaceofDalaiLamas.”可知。

29.A解析：由A中的disadvantage中最后一条内容“Waterqualityandquantitydownstreamcanbeaffected,whichCanhaveanimpactonplantlife.”可知答案为A。
