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

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

AnotherreasonforBotticelli'sunpopularitymayhavebeenthathisattitudetowardthestyle.ofclassicalartwasverydifferentfromthatofhiscontemporaries.Althoughhewasthoroughlyexposedtoclassicalart,heshowedlittleinterestinborrowingfrom,theclassicalstyle.Indeed,itisparadoxicalthatapainteroflarge-scaleclassicalsubjectsadoptedastyle.thatwas.onlyslightlysimilartothatofclassicalart.

Inanycase,whenviewersbegantoexaminemorecloselytherelationshipofBotticelli'sworktothetraditionofthefifteenthcenturyHorentineart,hisreputationbegantogrow.AnalysesandassessmentsofBotticellimadebetween1850and1870bytheartistsofthePre-Raphaelitemovement,aswellasbythewriterPater(althoughhe,unfortunately,basedhisassessmentonanincorrectanalysisofBotticelli'spersonality),inspiredanewappreciationofBotticellithroughouttheEnglish-speakingworld.YetBotticelli'swork,especiallytheSistinefrescoes,didnotgenerateworldwideattentionuntilitwasfinallysubjectedtoacomprehensiveandscrupulousanalysisbyHomein1908.Homerightlydemonstratedthatthefrescoessharedimportantfeatureswithpaintingsbyotherfifteenth-centuryFlorentines—featuressuchasskillfulrepresentationofanatomicalproportions,andofthehumanfigureinmotion.However,Homearguedthat.Botticellididnottreatthesequalitiesasendsinthemselves—rather,thatheemphasizedcleardepletionofastory,auniqueachievementandonethatmadethetraditionalFlorentinequalitieslesscentral.

BecauseofHome'semphasiscrucialtoanystudyofart,thetwentiethcenturyhascometoappreciateBotticelli'sa-chievements.

15.Four．

16.bringbring解析：根据上下文，此处意思为给他们带来快乐。带来用动词“bring”。所以此处应填“bring”。

17.InsteadInstead解析：由本句句意“…修一台烤箱或一台收音机，买一台新的、扔掉旧的更容易、更便宜…”可知，肯定是“不修”，又因为有介词of，所以应填intead。insteadof意为“不做某事”，是固定短语。

18.WarmWarm解析：由此句中的“contrastiveviews”可知，观点是相对的，此空所在短句意为“从…赞扬到冷酷的批评”，显然，应是“热烈的”。

19.somesome解析：关键是注意and前后一致。“somerationaland…emotional”，前面说促使顾客购买的动机有很多，有的是理性的，有的却是冲动。所以这里应该是some。故答案为some。

20.beingbeing解析：avoiddoingsth．意为“避免…”，avoid后必须跟名词或动名词。beovercritical意为“过分挑剔的”。

21.foundfound解析：此句意为“1,000名受访者中有70%的发现，相对于其他设备来说，在使用手机时人们表现出最差的礼仪”，所以答案为“found”。

22.workwork解析：本句意为“我们以前已经尝试过，但是不…。”显然，此空处应填“奏效，起作用”，英语中表达这一含义最地道的词就是work。

23.populationpopulation解析：由下一句“越来越多的人正在制造更多的垃圾。”可知，此处应指“膨胀的人口”，即explodingpopulation。

24.whatwhat解析：此题考查what引导的宾语从句。要注意分析句子中的成分，此空为listento后的宾语。所以此处应填引导词“what”。

25.foundfound解析：此句意为“1，000名受访者中有70％的发现，相对于其他设备来说，在使用手机时人们表现出最差的礼仪”，所以答案为“found”。

26.C解析：这个题考察的是对后面几段的归纳。首先在第三段开始“Dr．MaquetusedanelectronicdevicecalledPET…theypracticedataskduringtheday，andastheysleptduringthefollowingnight．”这是一种对比性的研究方法。后来的第四段最后“…theirresponsetimeswhentheywokeupwereevenquickerthanwhentheywenttosleep．”也采用了对比的分析研究，故应选C。

27.D解析：由第四段第一句“However，MacDonaldandotherswarmagainstusinginsurancepoliciespurelyasaninvestment．”可知。

28.A解析：作者的态度从文章第一句话和最后一句话就可以明显判断出来。第一句话说基因疗法是20世纪的伟大成就之一，最后一句话说“Everybodyrecognizesthatgenetherapyisaverygoodidea”，由此可见作者对基因疗法持积极乐观的态度。因此正确答案为A。

29.BB解析：由下—段第—句“Thepoker—lovingLouis—Dreyfusknew…”可知此空处填B最合适，因为“Louis-Dreyfus，scionof．．．”必定在下一段之前逻辑上才讲得通。

30.B解析：第一段中，作者
