B．exactlyC．commercially D．thoroughly解析：依據(jù)下文內(nèi)容，以及對比四個選項，明顯D項最符合文意。thoroughly意為“徹底地、完全地”。2．A．cloning B．imitatingC．chasing D．controlling解析：依據(jù)首句Humancloningtechnologycouldbeusedtoreverseheartattacks.可知選A。屬于原詞復現(xiàn)。3．A．where B．ifC．because D．a(chǎn)lthough解析：依據(jù)前后邏輯關系可知，此處指條件，故選B最佳。4．A．refused B．forbiddenC．contrasted D．encouraged解析：由空前的otherproblemsmaybesolvedifhumancloninganditstechnologyarenot可知，許多問題也能夠被解決，假如克隆技術不被禁止的話?；蛘哂沙ＷR也可知，目前克隆技術是被禁止運用的。故選B符合語境。5．A．nonviolent B．irresponsibleC．infertile D．incredible解析：依據(jù)下一句Currenttreatmentsforinfertility可知選C。屬于同源詞復現(xiàn)。6．A．imaginative B．successfulC．beneficial D．identical解析：依據(jù)下文Manycouplesrunoutoftimeandmoneywithoutsuccessfullyhavingchildren.可推知，目前對不孕癥的治療并不是很勝利。屬于同源詞復現(xiàn)，故選B符合語境。7．A．fear B．chance C．sense D．regret解析：依據(jù)空后的havingchildren可知，此處是指不孕的夫婦經(jīng)受身體上和情感上的苦痛過程，僅僅是為了很小的機會能擁有孩子。asmallchanceof意為“很少可能……、很小的機會……”。斟酌四個選項，只有B最符合語境。8．A．parents B．patientsC．doctors D．couples解析：依據(jù)本句后面的havingchildren可推知答案選D。9．A．possible B．rightC．memorable D．positive解析：由前文forasmall7ofhavingchildren可知不孕夫婦幾乎沒有機會能要小孩。依據(jù)空前的Humancloningcouldmakeit可知，克隆技術能解決這個問題，讓不孕夫婦有小孩比以往任何時候都更加有可能。故選A項最符合上下文邏輯。10．A．differing B．resultingC．suffering D．separating解析：明顯此處是指患上白血病的小孩和成年人。固定搭配sufferfrom在此意為“患上(疾病)”，故選C。11．A．benefits B．a(chǎn)greementsC．a(chǎn)dvantages D．characteristics解析：依據(jù)文章尾段最終一句中的letthebenefitsbegin可知此處指治療不孕有望是來自克隆技術的第一個好處之一。文章講到了克隆技術在醫(yī)學上的多種好處，這只是其中之一，下文還有。故此題選A項最佳。屬于原詞復現(xiàn)。12．A．combine B．spreadC．cure D．rescue解析：由空后的cancer可知，此處理應是指治愈癌癥。故選C正確。13．A．conditions B．operations C．symptoms D．diseases解析：斟酌四個選項，并結合空前的Cloningtechnologycanbeusedtotestforandperhapscure可知此處是推想克隆技術或許能夠治愈與基因相關的癌癥。依據(jù)目前的醫(yī)學技術，許多癌癥是很難治愈的疾病，故選D。14．A．moral B．reasonableC．new D．conservative解析：依據(jù)本句后面的內(nèi)容ifpeoplewill15theirfearsandletthebenefitsbegin不難推知，克隆技術到目前為止還是一種新的技術，有待科學家進一步探討。故答案選C最合適。15．A．increase B．treat C．release D．sacrifice解析：依據(jù)生活常識可知，許多人對克隆技術心懷恐驚和膽怯 ，認為這種技術會破壞社會的正常秩序。但從文章講到的克隆技術的種種好處看來，作者認為只要人們釋放心中的恐驚和正確開發(fā)利用克隆技術，這會是醫(yī)學領域上史無前例的進步。故此題選C最佳。Ⅳ.閱讀理解Researchadvancesoverthepastdecadehavetoldusthat,withalittlework,wehumanscanclonejustaboutanythingwewant,fromfrogstomonkeysandprobablyevenourselves!So,wecanclonethings,butwhywouldwewantto?Ofallthereasons,cloningformedicalpurposesmostprobablybenefitlargenumbersofpeople.Howmightcloningbeusedinmedicine?1．CloninganimalmodelsofdiseaseMuchofwhatresearcherslearnabouthumandiseasecomesfromstudyinganimalmodelssuchasmice.Often,animalmodelsaregeneticallyengineeredtocarrydisease-causingmutations(變異)intheirgenes.Creatingthesetransgenic(轉(zhuǎn)基因的)animalsisaprocessthatrequirestrial-and-errorandseveralgenerationsofbreeding(培育)．Cloningtechnologiesmightreducethetimeneededtomakeatransgenicanimalmodel,andtheresultwouldbeapopulationofgeneticallyidenticalanimalsforstudy.2．Cloningstemcells(干細胞)forthetreatmentofdiseasesStemcellsarethebody'sbuildingblocks,responsiblefordevelopingandrepairingthebodythroughoutlife.Asaresult,theymightbeusedtorepairdamagedordiseasedorgansandtissues.Researchersarecurrentlylookingupcloningasawaytocreatecertainhumanstemcellsforthetreatmentofdiseases.3．CloningfarmanimalsfordrugproductionFarmanimalssuchascows,sheepandgoatsarecurrentlybeinggeneticallyengineeredtoproducedrugsorproteinsthatareusefulinmedicine.Justlikecreatinganimalmodelsofdisease,cloningmightbeafasterwaytoproducelargenumbersofgeneticallyengineeredanimals.文章大意：本文主要介紹了克隆技術在醫(yī)學上的用處。1．ItcanbelearnedfromthesecondpurposethatcloningtechnologiescanbemainlyusedtoB.A．createdamagedordiseasedorgansandtissuesB．clonegeneticallydefinedhumanstemcellsC．developandmaintainthebodyD．repairthebodythroughoutlife解析：推理推斷題。由第五段“Researchersarecurrentlylookingupcloningasawaytocreatecertainhumanstemcellsforthetreatmentofdiseases”可推斷出。2．Accordingtothethirdpurpose,cloningtechnologiescanbemainlyusedtoA.A．speeduptheproducingofgeneticallyengineeredanimalsB．producedrugsorproteinsthatareusefulinmedicineC．raisegeneticallyengineeredcows,sheepandgoatsD．producelargeherdsofanimalsforhumanbeings解析：事實細微環(huán)節(jié)題。由第六段“Justlikecreatinganimalmodelsofdisease,cloningmightbeafasterwaytoproducelargenumbersofgeneticallyengineeredanimals.”可知是A答案。3．Whichofthefollowingstatementsistrueaccordingtothepassage？DA．Wecancloneourselveseasily.B．Cloningisjusthelpfulinmedicalfield.C．cloningisthefastestwaytoproducelargenumbersofgeneticallyengineeredanimals.D．Cloningformedicalpurposesmostprobablybenefitlargenumbersofpeople.解析：事實細微環(huán)節(jié)題。由第三段“Ofallthereasons,cloningformedicalpurposesmostprobablybenefitlargenumbersofpeople.”這句話可知。4．Whatisthemainideaofthepassage？CA．Cloning.B．theuseofcloning.C．theuseofcloninginmedicine.D．Cloningfarmanimalsfordrugproduction.解析：主旨大意題。通讀全文可知，本文主要介紹了克隆在醫(yī)學上的用處。Ⅴ.七選五依據(jù)短文內(nèi)容，從短文后的選項中選出能填入空白處的最佳選項。選項中有兩項為多余項。Weallknowbynowthatexerciseisgreatforyou.Butlet'sbehonest,sometimesfindingthatmotivationtoworkoutcanbealittledifficult.HereIamgoingtosharemytopreasonsforworkingout.Exercisecancompletelychangeyourfeeling.Whenyouworkout,yourbodyproducesendorphine,whichwillgiveyouarushofhappiness.1.DNexttimeyou'rehavingabadday,trygoingforafast-pacedrunortakingaspinningclass,andthedaywon'tseemsobadafterall.Exercisehelpsyoubecomesociable.WheneverImovetoanewcitytostudyorwork,Ilookforexerciseclasses,whereyoucanalwaysmeetlike-mindedpeople.2.CAndyouallshareacollectivefeelingofhappinesswhenthehardclassfinishes!3.AWeallknowthephysicaleffectsofexerciseonourbodiesbutwedon'talwaystalkaboutthementaleffects.Exercisemightgiveyoubeliefinyourselffrombeingcomfortablewithyourbodyandappearance.Thisnewfeelingmightevenhelpinyourworkorsociallife.Exercisemakesyoufeelstrongandfit.4.GIt'sagreatfeelingdoingsomethingyoucouldn'tdobeforeandknowingit'saresultofyourhardwork.So,nexttimeyou'refeelingdown,putyourtrainersonandgetsweating.Itmightnotbeeasyinthebeginningformostpeople.5.FA．Exercisemakesyoufeelconfident.B．Exercisehelpsyoureducestressandanxiety.C．Youcansupporteachotherduringadifficultworkout.D．Youwillfeelbetterafteraworkoutthanyoudidbeforeit.E．Youcanget
