40.Themanbehindthisnotion,JackMaple,isadandywhoaffectsdarkglasses,homburgs(翹邊帽)andtwo-toeshoes;yethehasbecomesomethingofalegendinAmerica'spolicedepartments.Forsomeyears,startinginNewYorkandmovingontohigh-crimespotssuchasNewOrleansandPhiladelphia,heandhisbusinesspartner,JohnLinderhavemarketedatwo-tiersystemforcuttingcrime.

First,policedepartmentshavetosortthemselvesout:rootoutcorruption,streamlinetheirbureaucracy,andmakemorecontactwiththepublic.Second,theyhavetoadoptacomputersystemcalledComstatwhichhelpsthemtoanalyzestatisticsofallmajorcrimes.Theseareconstantlykeyedintothecomputer,whichthendisplayswhereandwhentheyhaveoccurredonacolor-codedmap,enablingthepolicetomonitorcrimetrendsastheyhappenandtospothigh-crimeareas.InNewYork,Comstat'sstatisticalmapsareanalyzedeachweekatameetingofthecity'spolicechiefandprecinctcaptains.

MessrsMapleandLinder("specialistsincrime-reductionservices")havenodoubtthattheirsystemisamaincontributortothedropincrime.WhentheyintroduceditinNewOrleansinJanuary1997,violentcrimedroppedby22%inayear;whentheymerelystartedworkinginformallywiththepolicedepartmentinNewark,NewJersey,violentcrimefellby13%.Policedepartmentsarenowlininguptopayasmuchas$50,000amonthforthesetwomentoputthemstraight.

Probablyallthesenewpoliciesandbitsoftechnicalwizardry,addedtogether,havemadeabigdifferencetocrime.Butthereremainanomaliesthatcannotbeexplained,suchasthefactthatcrimeinWashingtonD.C.,hasfallenasfastasanywhere,althoughthepolicedepartmenthasbeencorruptandhopelessand,inlargestretchesofthecity,neitherpolicenorresidentsseemdisposedtofightthecriminalsintheirmidst.

Themoreimportantreasonforthefallincrimerates,manysay,isamuchlesssophisticatedone.Itisafactthatcrimerateshavedroppedastheimprisonmentratesoared.In1997thenationalincarcerationrate,at645per100000peoplewasmorethandoubletheratein1985,andthenumberofinmatesincityandcountyjailsroseby9.4%.almostdoubleitsannualaverageincreasesince1990.Surelysomecriminologistsargue,onesetoffiguresisthecauseoftheother.Itisprecisebecausemorepeoplearebeingsenttoprison,theyclaimthatcrimeratesarefalling.A1993studybytheNationalAcademyofSciencesactuallyconcludedthatthetriplingoftheprisonpopulationbetween1975and1989hadloweredviolentcrimeby10-15%.

16.toto解析：besubjectedto為固定搭配，“使遭受，使服從”的意思，要學會跨過其他成分尋找主干。所以此處應填介詞“to”。

17.reusereuse解析：由后一句“今天幾乎每件東西都可以被扔掉?！笨芍啊魏螙|西不再明智了?！敝械目仗帒獮椤霸倮谩保@樣前后兩句邏輯上才能合理。

18.notnot解析：此空前半句意為“我們真地生活在污染中，呼吸著它”，而后半句意為“它開始…我們的健康、幸福和文明?！憋@然，這是因果關系，故中間的surprisingly前只能加個否定詞not。

19.reasonsreasons解析：本段的第一句話提出問題，問為什么在結算處擺設了那么多的商品。很明顯，后面的文章對這個問題進行回答，并列舉了原因。故答案為reasons。

20.lessless解析：由此空前面的“deterioratedsharply”可知此空應填“更少的”，而不是“更多的”。

21.asas解析：此處為因果關系，意為“因為許多人沒有…”，因此此處應填填連詞“as”。

22.FortunatelyFortunately解析：由本句句意“…可以看到有解決辦法的希望了。”可知，此空應填“幸運的是”。

23.importantimportant解析：從本句后面的一句話可以看出，Adown-to-earthperson就算是重要的人物，他們也不會把這種顯赫寫在臉上。所以前面應填important。故答案為important。

24.itit解析：本句意為“‘污染’意思是弄臟——表層土或什么東西，通過引進雜質，這使…不健康或不干凈。”顯然，此空處應指topsoilorsomething，因為前面已出現，所以用it來代替。

25.amongamong解析：此句意為“后一種觀點得到了許多支持者，尤其…教育家?！憋@然，空處應填“在…中”，介詞among即有此意。

26.D解析：由短文第二段中的“…showedthat
