D.contamination解析:本题考查上下文语义和名词含义。interact“互动”,interface“结合,交界”,connection“连接”,contamination“接触,传染”。空白处前一句话讲到这种流感在鸟类中出现了很多起,才开始向人类传播。因此parsing鸟类和人类的交叉感染是符合上下文语义走向的。(2).【C2】

B.contracted

C.concentrated

D.infected解析:本题考查动词词义辨析。Contact是“接触”但未必感染,contract是“感染”,根据文章上下文含义,正确答案为contract。(4).【C4】

D.outbreak

√解析:本题考查语义。takeplace“发生”,happen“出现,发生”,outbreak“爆发”,根据语义,D为正确选项。(6).【C6】

A.accounts

B.numbers

C.counts

D.takes解析:本题考查语义和动词含义。做动词讲时,account“把……视作”,number“标号”,count“把……算入”,take“拿,取”。根据句意:有些研究者认为这些死亡数据有些夸大,因为WHO只会将严重到需要去医院就诊的病例算入在内。count是最贴切的选项。(7).【C7】

A.Moreover

B.Still

C.Furthermore

D.Thereafter解析:本题考查逻辑关系。moreover表示递进,still有让步的含义,意思是“尽管如此,仍然……”,thereby表示因果,furthermore表示递进。该题上一句讲到有些研究者认为这些死亡数据有些夸大,因为WHO只会将严重到需要去医院就诊的病例算入在内。空格后则强调该数字仍然是惊人的。因此这里选择有让步含义的副词still。(8).【C8】

A.given

B.giving

C.togive

D.speakingof解析:本题考查逻辑关系。这里需要原因和条件,只有given有此功能,意思是“鉴于,因为”。这里是连词。speakingof的意思是“谈到,谈起”。(9).【C9】

A.parsing

B.parsed

C.toparse

D.havingparsed解析:本题考查with引导的介宾短语充当状语。withsthdoingsth.,意思是“同时,实验室要探究病毒的分子构成”。(10).【C10】

B.potentially

C.potently

D.importantly解析:本题考查句子含义和副词。这里表示可能对人类的传染,只有potentially表示“可能,潜在地”。presently“现在,当下”,potently“有力地”,importantly“重要地”。四、PartⅣReadingComprehensionPlanesmayaccountforonly2percentoftheworld'scarbonemissions,butitisafiguredestinedtorise.Theaviationindustryisexpandingatadramaticrate,around5percentayear.TwiceasmanypassengersarelikelytobepassingthroughBritishairportsin2020comparedwithtoday,andthreetimesby2030.Asthedevelopedworldacknowledgesclimatechangewarnings,thecarbonemissionsfromotherindustrieswillfall.Theaviationindustry'soutputwillthereforeaccountforanevenlargerpercentageofemissions.Onecalculation,bytheClimateChangeResearch(CCR),suggeststheU.K.aviationindustrycouldendupaccountingforeverygramofourcarbonquotaby2040.Suchcalculationssupposeaircraftdesignerscannotcleanuptheiract,asuggestionfirmlyrejectedbyexpertswhopointtoamassiveresearchprogramaimedatcuttingfuelusebyplanesbyaround50percentby2020,amovethatwouldalsohalvetheircarbonemissions.Toreachthataim,akeyfactorwillbelightweightcomposites,materialsmadeofseveralcomponents,includingcarbonfibres.TheseareasstrongandflexibleasmetalbutaslightasplastiC.PlanessuchastheAirbusA340arealreadymadeofmaterialthatis10percentcarboncomposite.Thiscutsweight,decreasesfueluseandreducescarbonemission.Thenextgenerationofaircrafts,willmakeevenmoreuseofcomposites:atremendoussavinginweight,fuelandcarbon.Thenthereisthesimplematterofairtrafficcontrol.Atpresent,individualcountrieshavetheirownroutesforaircraftcrossingtheirairspaces."Essentiallyaircrafttravelondog-legsacrossEurope,andthatisveryinefficientintermsoffueluse,"saidDr.JohnGreen,oftheRoyalAeronauticalSociety."Weneedtorationalizeairtrafficcontrolsothatplanesflyinstraight,energy-efficientlines,anideathatisnowbeingdiscussedintheEU."Finally,thereisaviationfuel.Makingitecologicallyfriendlyposesthegreatestchallengesofall.Biofuelscanbeusedaspetrolanddieselsubstitutesforcarsandlorries,butnotinplanes."Biofuelisessentiallyalcohol,andthatburnsatthewrongtemperatureforaircraftengines,"saysGreen."Wecanusecoaltomakekerosene,whichwecouldburninaircraftengines,butthatdoesnothelptheissueofglobalwarming,ofcourse."Butthisdoesnotstopscientistsfromdreaming.Oneidea,putforwardbytheU.S.geneticistCraigVenterlastweek,wouldbetocreatemicro-organisms,fittedwithartificialchromosomes,whichcouldconvertsunlightintofuelsthatcouldbeburntinaircraft.Thesewouldnotinvolveburningfossilcarbonandwouldbetheperfectgreenfuel.Itisstillafar-offprospectbutrealistic,saybiologists.(1).ThefactthatpassengerspassingBritishairportswilldoubleoreventripleindicatesthat______.

A.compositesthemselvesareverylight,strongandasflexibleasmetal

B.compositescanreducetheplaneweightleadingtolessfuelconsumptionandcarbonemissions

C.compositescancauselesscarbonemissionsintheprocessoflying

A.thepriorityofprotectingtheenvironment

B.thesamehumanpropensityasmentionedpreviously

C.thebeststrategyofreducingtheenvironmentalthreat

D.thedefinitehugeuncertaintiesabouttheclimaticeffects解析:B选项中的propensity指的是人类低估自身对地球影响的倾向,所以才会导致肆无忌惮用各种方式破坏环境,而大自然却无法同期抵消如此巨大的破坏力量。这也是全文的主旨,对风能分离的展示正是为了说明在寻找替代能源的尝试中,眼下没有风险的方式或许未来会有极为可怕的后果。(3).Theauthorarguesthatitwouldbeunfortunatetoreplacefossilfuelsonlytofindoutthat______.
