.UNIT1十年之前，南希做了許許多多美國人夢寐以求的事。她辭去了經(jīng)理職位，在鄰近地區(qū)開了一家家用器材商店。像南希這樣的人作出這種決定主要是出于改善生活質(zhì)量的愿望。然而，經(jīng)營小本生意絕非易事。在失去穩(wěn)定的收入后，南希不得不削減日常開支。有時候她甚至沒有錢支付她所需要的種種保險的費用。有一次她連電話費也付不起，只得向她的父母親借錢。Adecadeago,NancydidwhatsomanyAmericansdreamabout.Shequitanexecutivepositionandopen/setupahouseholdequipmentstoreinherneighborhood.PeoplelikeNancymadethedecisionprimarilybecauseoftheirdesiretoimprovethequalityoftheirlives.But,torunasmallbusinessisbyonmeansaneasyjob.Withouthersteadyincome,Nancyhadtocutbackonherdailyexpenses.Sometimesshedidnothavethemoneytopaythepremiumsforvariouskindsofinsurancesheneeded.Onceshecouldnotupthephonebillandhadtoaskherparentstoloanhersomemoney.Fortunately,throughherownhardwork,shehadnowgotthroughthemostdifficulttime.Sheisdeterminedtocontinuepursinghervisionofabetterlife.UNIT2幾個逃跑的奴隸被捕捉奴隸的人包圍。他將逃跑的奴隸喬裝打扮一番，成功地躲避了追捕。另外，他后會到來。Henson'spainfullifeasaslavestrengthenedhisdeterminationtostruggleforfreedom.Shortlyafterheachievedfreedomhebecameamemberofanorganizationthatassistedfugitiveslaves.HesecretlyreturnedtotheUnitedStatesfromCanadaseveraltimestohelpotherstotraveltheUndergroundRailroadtofreedom.OncesomeslavecatchersclosedinontheescapingslavesandHensonwhentheywereontherun.Hedisguisedthemandsuccessfullyavoidedcapture.Inaddition,laterhebuiltasmallsettlementinDresdeninCanadaforescapedslaves,settingupachapelandaschoolwheretheycouldlearnusefulwaysofmakingaliving.Heheldtotheconvictionthatslaverywouldbeabolished,alltheslaveswouldbeliberated,andthedaywasboundtocomewhenracialdiscriminationnolongerexisted.UNIT3在美國每隔15BURGLARYBURGLAR)光顧了兩百多萬戶人家。人們實際上幾乎無法將蓄意行竊的盜賊拒之門外，所能做的只是設法阻攔他片刻，從而使其暴露在巡警（POLICEPATROL）或附近溜達的人們面前。常識告訴我們光照是犯罪行為的障礙物。家門口必須安裝一盞燈，并在晚間開著。不管你是否相信，有些人，尤其是最晚進家的孩子，晚上進屋后不把門鎖上?？招拈T（DOOROFHOLLOWCORESOLIDCORE）門或鐵門，因為竊賊很難將它們撬開。如果你有意購買報警裝置，別忘了索要報警器的標志，并把它們張貼在窗戶和門上。最后，提醒一句，外出旅游時，一定要請一位信得過的鄰居，在DOORSTEP廣告一樣使大家都知道你家里沒人。Aburglaryisreportedevery15secondsintheUnitedStates.Statisticsshowburglarsenteredmorethan2millionhomeslastyear.Actuallyitisimpossibletokeepadeterminedburglarout.Allyoucandoisdiscouragehimforafewminutes,thusexposehimtopolicepatrolsorthosewanderingaround.Commonsensetellsusthatlightingisabarriertocriminalactivity.Alightshouldbefixedinthedoorwayandswitchedonatnight.Believeitornot,somepeople,particularlychildrenwhohappentobethelasttocomein,leavetheirdoorsonthelatchatnight.Doorsofhollowcore,evenwhenlocked,tobreak-ins.Thusdoorsofsolidcoreorsteelaremuchpreferredastheymakeitdifficultfortheburglartopryopen.Ifyoudecidetobuyanalarmdevice,besuretoaskforitssignsthemuponbothwindowsanddoors.Finally,awordofwarning---whenyoutravel,makesurethatyouhaveatrustedneighborcollectandkeepallthedeliveriesofnewspapersandmailuntilyoureturn.Thisisbecauseacollectionofnewspapersandmailonthefrontdoorsteporinyourmailboxisanadvertisementthatnooneishome.UNIT4式尋找他們。有的密切觀察稀有放射性（RADIOACTIVE）元素水平特別高的星球，他們認為那些元素產(chǎn)生于人類尚未理解的外星人技術(shù)。有的試圖從宇宙“噪音”中分離出無線電信號。而有的則宣稱已經(jīng)看辛努力是完全值得的。Theextraterrestrialhasbeenatopicofinteresttoexpertsandlaymen/nonprofessionalsalike.Researchersofvariousnationalitiesandorganizationsareadoptingdifferentmodesofinvestigationinsearchofextraterrestrials.Somemakeaofstarswithextremelyhighlevelsofrare,radioactiveelements.Theybelievethoseelementshaveresultedfromextraterrestrialtechnologythatisstillbeyondhumanwitstounderstand.Sometrytoisolateradionoisefromthe"noise"oftheuniverse.Andsomeclaimthattheyhavecaughtsightofextraterrestrialsandcanevendescribetheirappearanceindetail.Researchersworkupthecomplicateddatatheycollectintoaseriesofreportsandnodefiniteanswerhasyetbeenfound,theexplorers'hopeshowsnosignoffadingoutonaccountoftheirfrustrationsandtheyholdtothebeliefthattheirhardeffortswillproveworthwhile.UNIT5在感恩節(jié)的氣氛中，喬治并沒有跟朋友們一起慶祝節(jié)日，卻沉浸于閱讀他父親留給他的日記。他的父為他所做的許多具體事情。喬治的父親過去經(jīng)常向他強調(diào)必須經(jīng)歷各種艱難困苦去追求卓越（EXCELLENCE感激是高尚者的標志”這句伊索（AESOP）名言來教導他要把懂得感激放在最重要的位置。AmidtheatmosphereofThanksgiving,ratherthanjoininghisfriendsincelebrationoftheholiday,Georgewasimmersedinthediarylefttohimbyhisfather,whodiedatseaafterhecompletedtwosuccessivetripsaroundtheworld.ThediarybroughtbackeverymomentGeorgehadspentwithhisfatherandmanyofthespecificthingshisfatherdidonhisbehalf.George'sfatherusedtoimpressonhimtheneedstoundergoallkindsofhardshipinquestofexcellence.Healsotaughthimthatnothingintheworldcouldbetakenforgranted.Eventoday,GeorgestillremembershowhisfatherwouldquoteAesop'sfamoussayingisthesignofnoblesouls"andtellhimtoaccordthegreatestimportancetoit.UNIT6我們到處都能看到“搶眼”的青年藝術(shù)家。他們要么一年四季都穿著破舊的牛仔褲；要么大冬天也打著赤腳；要么飲酒過度；要么就是抱著創(chuàng)作一部杰作的幻想，實際上并不做任何創(chuàng)作的事。其實，他們了，只有通過不懈的努力才能獲得成功。Hereandthereweseeyoungartistswhostandoutfromotherpeople.Theymaybeinworn-outjeansalltheyearround,orwalkinbarefeeteveninwinter,ordrinktoexcess,orclingtothefancyofcreatingamasterpiecewithoutactuallydoinganycreativework.Infact,manyofthemactlikethisjusttolookthepart,ortobe"intuneswith"otherartists.Theyhaveforgottenthatonlythroughpersistenteffortcanoneachievesuccess.UNIT7湯姆生來跛足，有一條腿不管用。他很小的時候起就懂得，除非他努力擺脫（RISEABOVE）自身的局限，他是無力謀生的；而除非他能獨立謀生，他就不可能得到他人的尊敬。這是他要贏得做人的尊
