A.thelowesttemperaturethereis40℃B.thedepthoficeis3,000metresC.theicehasexistedfor15,000yearsD.snowfallsarekeptincertainpatterns答案:D解析:細(xì)節(jié)理解題。第三段中的“Theyfigureoutthattheareawheresummertemperaturescanfallto40℃,hasatleast900,000yearsofsnowfalls,keptasneatlyasthegrowthringsofatree.”說明科學(xué)家們發(fā)現(xiàn),積雪保持著一定的模式。2Theinformationoftheglobalclimateconditionsinthepastcanbeobtainedthrough.

A.separatingcarbondioxidefromtheairB.examiningthegrowthringsoftreesCparingtemperaturesindifferentareasD.studyingtheiceandaircaughtineachlayer答案:D解析:細(xì)節(jié)理解題。根據(jù)第三段中的“Andtheiceandaircaughtineachlayerhavebeguntoanswerquestionsabouttheclimatesinthepast.”可判斷出對沉積在各層的雪和空氣進(jìn)行研究可以知道過去的氣候狀況。3WecaninferfromEricWolff’swordsthat.

A.thereissomethingwrongwiththedataB.thegreenhouseeffectisalwaysabadthingC.anewiceagewillnoteinthenearfutureD.thegreenhousegaswillgetthickinthefuture答案:C解析:推理判斷題。根據(jù)倒數(shù)第二段艾瑞克·沃爾夫說的“...anewiceageisnothangingoverourheads...”可判斷出,他認(rèn)為新的冰川時代不會很快到來。4Whatwouldbethebesttitleforthepassage?A.ResearchovertheAntarcticareaB.Warmperiodtolastabout15,000yearsC.ReportontheeighticeagesinthepastD.Hollywoodmoviesandtheglobalclimate答案:B解析:主旨大意題。閱讀全文可知,本文主要敘述了作者對全球氣候變化的觀點以及對溫室效應(yīng)的態(tài)度。D項明顯偏離主題,可排除;A項過于籠統(tǒng),沒有提及氣候問題;C項只是文章內(nèi)容的一個側(cè)面;只有B項適合用作標(biāo)題。B(2015·陜西高考)Theproductionofcoffeebeansisahuge,profitablebusiness,but,unfortunately,fullsunproductionistakingovertheindustryandbringingaboutalotofdamage.Thechangeinhowcoffeeisgrownfromshadegrownproductiontofullsunproductionendangerstheveryexistenceofcertainanimalsandbirds,andevendisturbstheworld’secologicalbalance.Onalocallevel,thedamageoftheforestrequiredbyfullsunfieldsaffectsthearea’sbirdsandanimals.Theshadeoftheforesttreesprovidesahomeforbirdsandotherspecies(物種)thatdependonthetrees’flowersandfruits.Fullsuncoffeegrowersdestroythisforesthome.Asaresult,manyspeciesarequicklydyingout.Onamoregloballevel,thedestructionoftherainforestforfullsuncoffeefieldsalsothreatens(威脅)humanlife.Medicalresearchoftenmakesuseoftheforests’plantandanimallife,andthedestructionofsuchspeciescouldpreventresearchersfromfindingcuresforcertaindiseases.Inaddition,newcoffeegrowingtechniquesarepoisoningthewaterlocally,andeventuallytheworld’sgroundwater.Bothlocallyandglobally,thecontinuedspreadoffullsuncoffeeplantations(種植園)couldmeanthedestructionoftherainforestecology.Thelossofshadetreesisalreadycausingaslightchangeintheworld’sclimate,andstudiesshowthatthelossofoxygengivingtreesalsoleadstoairpollutionandglobalwarming.Moreover,thenewgrowingtechniquesarecontributingtoacidic(酸性的)soilconditions.Itisobviousthatthewaymuchcoffeeisgrownaffectsmanyaspectsoflife,fromthelocalenvironmenttotheglobalecology.Butconsumersdohaveachoice.Theycanpurchaseshadegrowncoffeewheneverpossible,althoughatahighercost.Thefuturehealthoftheplanetandmankindissurelyworthmorethananinexpensivecupofcoffee.5WhatcanwelearnaboutfullsuncoffeeproductionfromParagraph4?A.Itlimitsthespreadofnewgrowingtechniques.B.Itleadstoairpollutionandglobalwarming.C.Itslowsdownthelossofshadetrees.D.Itimproveslocalsoilconditions.答案:B解析:細(xì)節(jié)理解題。從第四段中的“causingaslightchangeintheworld’sclimate”以及“l(fā)eadstoairpollutionandglobalwarming”可知B項正確。6Thepurposeofthetextisto.

A.entertain B.advertiseC.instruct D.persuade答案:D解析:推理判斷題。從文章最后一句話“Thefuturehealthoftheplanetandmankindissurelyworthmorethananinexpensivecupofcoffee.”可以看出作者希望人們不要為了一杯便宜的咖啡而毀了地球和人類,所以是帶著勸說的意圖寫這篇文章的。7Wheredoesthistextprobablyefrom?A.Anagriculturalmagazine.B.Amedicaljournal.C.Anengineeringtextbook.D.Atouristguide.答案:A解析:推理判斷題?？Х确N植是跟農(nóng)業(yè)相關(guān)的話題,所以該文可能會出現(xiàn)在農(nóng)業(yè)雜志上,故選A項。8Whichofthefollowingshowsthestructureofthewholetext?(P:Paragraph)答案:A解析:組織結(jié)構(gòu)題。本文共包括五段。第一段概述fullsun咖啡種植取代shadegrown咖啡種植已經(jīng)對地球的整個生態(tài)產(chǎn)生了極大的負(fù)面影響。第二、三、四段分別從alocallevel,amoregloballevel以及bothlocallyandglobally三個方面闡釋fullsun咖啡種植的危害。第五段歸納fullsun咖啡種植對人類多方面的影響,并提醒人們理智地對待這一問題。所以該文結(jié)構(gòu)為:總—分—總。故A項正確?！镂濉⑵哌x五閱讀理解1TherewerefewpeopleontheEarth,andnaturalresourcesseemedtobeunlimited.Todaythingsaredifferent.Theworldhasbeetoocrowded.Weareusingupourresourcestooquickly,andatthesametimewearepollutingourenvironmentwithdangerouschemicals.2
