切从他喜欢的面包店里买来的巧克力蛋糕，当然还唱了“生日歌”，否则宴会就不算完整了。吉米一次次地问：“该切蛋糕了吧？”等用完餐和送完礼物后，吉米再也控制不住了。他焦急地等着点上蜡烛，然后在我们“生日快乐”的歌声中，一口长气吹灭了蜡烛。户然而吉米对我们的努力还是感到不满足。他纵身跳到椅子上，直挺着身子，双手食指朝天，一边喊一边指挥我们唱歌：“再来次！”我们全力以赴地唱。待我们唱完时，他翘起两个拇指喊道：“好极了！”本来我们想让他知道，无论世上有多难的事情，总是有人来关心他。现在反倒是提醒了我们自己。对于吉米来说，我们唱歌时的爱心，是他心中额外的礼物，但是他原先更想看到的，是别人再次感到快乐。有如父亲的去世一夜之间改变了吉米的世界，911也改变了我们的生活；我们熟悉的世界不复存在了。但是，当我们为吉米唱歌，相互紧拥，祈祷全球和平时，我们也意识到，朋友、家人间永恒的爱和支持可以让我们克服生活中的任何困难。吉米以朴素的方式为我们协调了眼前的一切，他做到这一点并不令人吃惊。吉米的爱可以征服一切，这是任何东西都限制不了的。U2IronandtheEffectsofExerciseSportsmedicineexpertshaveobservedforyearsthatenduranceathletes,particularlyfemales,frequentlyhaveirondeficiencies.NowanewstudybyateamofPurdueUniversityresearcherssuggeststhatevenmoderateexercisemayleadtoreducedironinthebloodofwomen.Wefoundthatwomenwhowerenormallyinactiveandthenstartedaprogramofmoderateexerciseshowedevidenceofironloss,saysRoseanneM.Lyle,associateprofessoratPurdue.Herstudyof62formerlyinactivewomenwhobeganexercisingthreetimesaweekforsixmonthswaspublishedinthejournalMedicine&ScienceinSports&Exercise.Womenwhoconsumedadditionalmeatortookironsupplementswereabletobounceback,shenotes.Butthenewexerciserswhofollowedtheirnormaldietshowedadecreaseinironlevels.Irondeficiencyisverycommonamongwomeningeneral,affectingoneinfourfemaleteenagersandoneinfivewomenaged18to45,respectively.Buttheratioisevengreateramongactivewomen,affectingupto80percentoffemaleenduranceathletes.Thismeans,Lylesays,thattoomanywomenignoretheamountofirontheytakein;.Womenofchild-bearingageareatgreatestrisk,sincetheirmonthlybleedingisamajorsourceofironloss.Plus,manyhealth-consciouswomenincreasetheirriskbyrejectingredmeat,whichcontainsthemosteasilyabsorbedformofiron.Andbecausewomenoftenrestricttheirdietinanefforttocontrolweight,theymaynotconsumeenoughiron-richfood,andareliabletoexperienceadeficiency.Theaveragewomantakesinonlytwothirdsoftherecommendeddailyallowanceforiron,notesanotherexpert.Forawomanwhoalreadyhasapoorironstatus,anyadditionalironlossfromexercisemaybeenoughtotipherovertheedgeintoamoreseriousdeficiency,notestheexpert.Exercisecanresultinironlossthroughavarietyofmechanisms.Someironislostinsweat,and,forunknownreasons,intenseenduranceexerciseissometimesassociatedwithbleedingofthedigestivesystem.Athletesinhigh-impactsportssuchasrunningmayalsoloseironthroughaphenomenonwheresmallbloodvesselsinthefeetleakblood.Therearethreestagesofirondeficiency.Thefirstandmostcommonishavinglowironreserves,aconditionthattypicallyhasnosymptoms.Fatigueandpoorperformancemaybegintoappearinthesecondstageofdeficiency,whennotenoughironispresenttoformthemoleculesofbloodproteinthattransportoxygentotheworkingmuscles.Inthethirdandfinalstage,peopleoftenfeelweak,tired,andoutofbreathandexerciseperformanceisseverelycompromised.Peoplethinkthatiftheyrenotatthethirdstage,nothingiswrong,butthatsnottrue,saysJohnL.Beard,whohelpeddesignthePurduestudy.Yourenotstage3untilyourironreservesgotozero,andifyouwaituntilthatpoint,youreintrouble.However,mostpeoplewithlowironreservesdontknowtheyhaveadeficiency,becausetraditionalmethodsofcalculatingtheamountofironinblood(bycheckinglevelsofthebloodproteinthattransportsoxygen)arenotsufficient,Beardstates.Instead,itsimportanttochecklevelsofadifferentcompound,whichindicatestheamountofstorageofironintheblood.Whileactive,child-bearingagewomenaremostlikelytohavelowironstores,henotes,Menarenotsafe,especiallyiftheydonteatmeatandhaveahighlevelofphysicalactivity.(Anestimated15percentofmalelongdistancerunnershavelowironstores.)Beardandotherexpertssayitsadvisableforpeopleinthesegroupstohaveayearlybloodtesttocheckbloodironreserves.Ifironlevelsarelow,talkwithaphysiciantoseeifthedeficiencyshouldbecorrectedbymodifyingyourdietorbytakingsupplements.Ingeneral,itsbettertoundotheproblembyaddingmoreiron-richfoodstothediet,becauseironsupplementscanhaveseriousshortcomings.Supplementsmayproduceafeelingofwantingtothrowup,andmaybepoisonousinsomecases.Thebestsourcesofiron,andtheonlysourcesoftheformofironmostreadilyabsorbedbythebody,aremeat,chicken,andfish.Goodsourcesofotherformsofironincludedates,beans,andsomeleafygreenvegetables.Selectbreadsandcerealswiththewordsiron-addedonthelabel,writessportsdietexpertNancyClark.Thisaddedironsupplementsthesmallamountthatnaturallyoccursingrains.EatthesefoodswithplentifulVitaminC(forexample,drinkorangejuicewithcerealorputatomatoonasandwich)toenhancetheamountofironabsorbed.Clarkalsorecommendscookinginironpans,asfoodcanderiveironfromthepanduringthecookingprocess.Theironcontentoftomatosaucecookedinanironpotforthreehoursshowedastrikingincrease,thelevelgoingupnearly30times,shewrites.Andpeoplewhoarelikelytohavelowironshouldavoiddrinkingcoffeeorteawithmeals,shesays,sincesubstancesinthesedrinkscaninterferewithironbeingabsorbedintothebody.Activewomenneedtobealotmorecarefulabouttheirfoodchoices,sumsupPurduesLyle.Ifyoupayattentiontowarningsignsbeforeironreservesaregone,youcanremedythedeficiencybeforeitreallybecomesaproblem.铁与运动的关系运动医学专家经过多年的观察，发现耐力运动员，特别是女性，经常会缺铁。普渡大学研究人员进行的一项新的研究表明：即使是适度的锻炼，也可能会降低女性血液中的铁含量。“我们发现，那些通常不运动的女性一旦开始适度的锻炼，就会出现铁含量下降的迹象，”普渡大学罗斯安妮M.莱尔副教授说。她对62名妇女进行了研究，并将研究结果发表在体育运动医学与科学杂志上。这些妇女原先不怎么运动，后来开始了为期6个月、每周3次的锻炼。莱尔指出：“那些增食肉类食品或服用铁质补剂的女性能够恢复到健康状态。但突然参加锻炼却仍沿用旧食谱的人则显示出铁含量降低。”缺铁在女性中是很常见的，每四个十几岁的少女中有一人缺铁，每五个18至45岁的女性中有一人缺铁。而在积极锻炼的妇女中这一比例更高，女耐力运动员中，缺铁者比例则高达80%。莱尔说，这意味着“太多女性忽视了自己摄入的铁含量”。育龄女性危险最大，因为月经是铁流失的重要原因之一。此外，许多保健意识太强的女性也很危险，因为她们拒绝食用牛肉或羊肉，而这些肉中含有的铁最易被吸收。而且，由于女性常常为了控制体重而节食，从而未能摄取足够的含铁丰富的食物，结果可能导致缺铁。另一名专家指出，“普通女性每天摄入的铁只是应摄入量的三分之二。”他指出，“对于那些已经缺铁的女性，任何因锻炼而产生的更多铁质流失都足以导致体内缺铁状况的恶化。”运动可能通过多种机制导致铁流失。有些铁随汗液流失。另外，由于某些未知的原因，高强度的耐力运动有时会引起消化系统内出血。运动员从事跑步之类高强度剧烈运动，也可能会因为足部血管失血的现象而使铁质流失。缺铁分为三个阶段：第一也即最常见的阶段，是铁质储量不足。这一阶段一般没有症状。到了缺铁的第二阶段，就会出现疲倦和力不从心，此时体内已没有足够的铁来形成血蛋白分子，将氧输至运动肌肉。在第三即最后阶段，人常常感到虚弱、疲乏无力、喘不过气，运动成绩大打折扣。“人们认为，只要不到第三阶段就不会有什么问题。这种想法是不对的。”帮助设计普渡大学研究的约翰L.比尔德说。“只有当你的铁储量为零时，你才会进入第三阶段。而你若坐等到这个时候，你的麻烦就大了。”然而，比尔德指出，大多数铁质储量低的人并未意识到自己缺铁，因为传统的检测血液中铁含量的方法检验血液中输送氧气的血蛋白的含量是不够的。其实，有必要检查血液中另一种混合成分的含量，它可以显示血液中的铁含量。他还指出，虽然积极锻炼的育龄妇女最有可能铁含量低，“但男性也并非不缺铁，尤其是在他们不吃肉类而又从事高强度的体力活动的情况下。”（估计有15%的男性长跑运动员铁含量低。）比尔德和其他专家都说，对这些人而言，最好每年验一次血，以测定血液中的铁含量。如果铁含量低，就要去看医生，以确定是否该通过调整饮食或服用铁质补剂来校正不足。一般说来，解决问题的最好方法是在食谱中增加含铁丰富的食物，因为铁质补剂可能存在严重缺陷。“服用铁质补剂可能使人想呕吐，有时甚至还会引起中毒。最好的铁来源，以及唯一最易为身体所吸收的铁来源，是肉、鸡和鱼。其他较好的铁质来源包括枣、豆类和一些多叶绿色蔬菜。”“选择那些标有加铁字样的面包和麦片，”运动营养专家南希克拉克写道，“这些增加的铁质补充了谷物中自然含铁量的不足。将这些食物与含有大量维生素C的食物一起食用比如吃麦片时喝橘子汁，或在三明治内夹上番茄可以促进铁质吸收。”克拉克还建议用铁锅烹食，因为烹调过程中食物能从铁锅中吸收铁质。她写道，“在铁锅内烹煮了3个小时的番茄汁，其铁含量大大提高，增加到原来的30倍左右。”她说，铁含量可能低的人，吃饭时应避免喝咖啡或饮茶，因为这些饮料中所含的物质会妨碍身体对铁质的吸收。“运动女性应特别注意选择饮食。”普渡大学的莱尔总结说：“如果你在铁含量流失之前就注意到了警告信号，你就可以在它真正成为问题之前弥补铁质的不足。”U3WherePrinciplesComeFirstTheHydeSchooloperatesontheprinciplethatifyouteachstudentsthemeritofsuchvaluesastruth,courage,integrity,leadership,curiosityandconcern,thenacademicachievementnaturallyfollows.HydeSchoolfounderJosephGauldclaimssuccesswiththeprogramatthe$18,000-a-yearhighschoolinBath,Maine,whichhasreceivedconsiderablepublicityforitsworkwithtroubledyoungsters.Wedontseeourselvesasaschoolforatypeofkid,saysMalcolmGauld,Josephsson,whograduatedfromHydeandisnowheadmaster.Weseeourselvesaspreparingkidsforawayoflifebycultivatingacomprehensivesetofprinciplesthatcanaffectallkids.Now,JoeGauldistryingtospreadhiscontroversialCharacterFirstideatopublic,inner-cityschoolswillingtousethetaxdollarsspentonthetraditionalprogramforthenewapproach.ThefirstHydepublicschoolprogramopenedinSeptember1992.Withinmonthstheprogramwassuspended.Teachersprotestedtheprogramsdemandsandthestrainassociatedwithmoreintensework.Thisfall,theHydeFoundationisscheduledtobeginapreliminarypublicschoolprograminBaltimore.TeacherswillbetrainedtolaterworkthroughouttheentireBaltimoresystem.OtherUSschoolmanagersareeyeingtheprogram,too.Lastfall,theHydeFoundationopenedamagnetprogramwithinapublichighschoolinthesuburbsofNewHaven,Connecticut,overparentsprotests.Thecommunityfearedtheschoolwouldattractinner-cityminorityandtroubledstudents.AsinMainethequestfortruthisalsowidespreadattheschoolinConnecticut.InoneEnglishclass,the11studentsspendthelastfiveminutesinanenergeticexchangeevaluatingtheirclassperformanceforthedayona1-10scale.Igeta10.Ichallengethat.Youdidntdoeitheryourgrammaroryourspellinghomework.OK,aseven.Yououghttogetasix.Wait,Iputmybesteffortforthhere.Yeah,butyoudidntaskquestionstoday.Explaininghisapproachtoeducation,JoeGauldsaystheconventionaleducationsystemcannotbereformed.Henotesnoamountofchangewiththehorseandcarriagewillproduceanautomobile.TheHydeSchoolassumeseveryhumanbeinghasauniquepotentialthatisbasedoncharacter,notintelligenceorwealth.Conscienceandhardworkarevalued.Successismeasuredbygrowth,notacademicachievement.Studentsarerequiredtotakeresponsibilityforeachother.ToavoidthecontroversyofothercharacterprogramsusedinUSschools,Gauldsaystheconceptofdoingyourbesthasnothingtodowithforcingthestudentstoacceptaparticularsetofmoralsorreligiousvalues.TheHydecurriculumissimilartoconventionalschoolsthatprovidepreparationforcollege,completewithEnglish,history,mathandscience.Butallstudentsarerequiredtotakeperformingartsandsports,andprovideacommunityservice.Foreachcourse,studentsgetagradeforacademicachievementandforbesteffort.AtBath,97%ofthegraduatesattendfour-yearcolleges.CommitmentamongparentsisakeyingredientintheHydemixture.Forthestudenttogainadmission,parentsalsomustagreetoacceptanddemonstratetheschoolsphilosophiesandoutlook.Theparentsagreeinwritingtomeetmonthlyinoneof20regionalgroups,gotoayearlythree-dayregionalretreat,andspendatleastthreetimesayearinworkshops,discussiongroupsandseminarsatBath.ParentsofMainestudentshaveanattendancerateof95%inthemanysessions.JoeandMalcolmGauldbothsaychildrentendtodotheirutmostwhentheyseetheirparentsmakingsimilarefforts.Thebiggestobstacleformanyparents,theysay,istorealizetheirownweaknesses.Theprocessforpublicschoolparentsisstillbeingworkedout,withalotmoredifficultybecauseitisdifficulttoconvinceparentsthatitisworthwhileforthemtoparticipate.Ofthe100studentsenrolledinNewHaven,about30%oftheparentsattendspecialmeetings.Thelowatt
