39.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.

16.readyready解析：顧客來到結(jié)算處，說明他們準備好了要付賬。bereadyto的意思是“準備好了做某事”。故答案為ready。

17.dumpingdumping解析：由本句句意“通過將污水和化學(xué)物質(zhì)…入河流和湖泊，…”可知，此空處顯然應(yīng)為“倒”。又因為介詞后只能用dumping，而不能用dump。

18.drinkingdrinking解析：由本句句意“通過將污水和化學(xué)物質(zhì)倒入河流和湖泊，我們已經(jīng)污染了我們的…水?！憋@然，此空處應(yīng)為“飲用”。

19.lookinglooking解析：與介詞for的固定搭配，意為“尋求…”，這里指的是尋求新的價值觀。所以此處應(yīng)填“l(fā)ooking”。

20.outout解析：handout意為“分發(fā)，施舍”，為固定短語。

21.thethe解析：此處缺冠詞，在年輕人之間，用the表示特指。所以此處應(yīng)填“the”。

22.complycomply解析：此處句意為“他們會很懊惱的服從”，表示服從，遵從的短語是complywith。所以此處應(yīng)填“comply”。

23.especiallyespecially解析：“Around1980many．Japanese，______youngpeople…”，“1980年左右許多日本人，尤其是年輕人…”，所以此處應(yīng)填“especially”。

24.youngyoung解析：本文均是在講年輕的腦力工作者，故此空所應(yīng)填的用于修飾“collegegraduates”的詞也應(yīng)是“年輕的”。

25.surveysurvey解析：根據(jù)后面的數(shù)據(jù)，空缺處指的是1993年的一項調(diào)查問卷，所以此處應(yīng)填“survey”。

26.D解析：fib意為“撒小謊”。

27.C解析：由C中的第一段最后一句話“Thissourcebook…andprovidespolicyadvice，includingtheuseofcleantechnologiesandenvironmentallysoundproductiontechniques，．．．．”可知。

28.B解析：書評二中最后幾句話提到了Stiglitz對RubinandSummers，F(xiàn)ischer，theNO．2officialanddefactochiefexecutiveoftheIMF的批評，“…theyhadtoomuchfaiththatmarketscouldtransform.poorcountriesovernight．Helabelsthesethreemenmarketfundamentalists”都可以看出題目中包含的信息。所以本題應(yīng)選B。

29.EE解析：文章的最后一段中指出“averyfew”、“theelitefew”，而選項中的“averysmallgroupof‘scholars’”也正是指出了這種情況，故應(yīng)選E。

30.D解析：由短文最后一段中的“Butnewmaterialshavenoimpactuntiltheyaremadeintoproducts．．．willdeterm
