Fromthelossofwildlifetotherisingsealevels,wehumansarewellawareoftheproblemsthatclimatechangecouldcause.Whileitseemsthatsuchissueswon’taffectmostofusdirectly,itlooksthatfuturegenerationscouldgrowupwithoutsomethingthatmanyofusnowtakeforgranted:chocolate.AccordingtoareportpublishedbytheUSNationalOceanicandAtmosphericAdministration,theclimatechangesintheregionsthatproducecacao—theplantfromwhichchocolateisproduced—maymeanthatcacaowillsoonbecomeextinct.Mostoftheworld’scacaogrowsincountrieswhichareclosetotheequator,withoverhalfofitgrowinginAfricannationslikeGhanaandIvoryCoast.It’spredictedthatbytheyearof2050,climatechangewillhaveacceleratedtherateatwhichtemperaturesinthesecountriesrise,makingitextremelydifficultforcacaotogrowthere.However,theproblemdoesn’texistinincreasedheat,butinlowerhumidity(濕度),asit’sbelievedthatrainfallwillstayatthesamelevelifthetemperaturerises.“Inotherwords,withhighertemperaturessqueezingmoreandmorewateroutofsoilandplants,it’sunlikelythatrainfallwillincreaseenoughtooffsetthemoisture(含水量)loss,”notedMitchellRon,thereport’sauthor.Tohelpsolvethisproblem,researchersfromBerkeleyUniversityintheUSareworkingonchangingtheDNAofcacaoplantstoallowthemtosurviveindrierconditionsbyusinggeneeditingtechnology,accordingtoUS

News.

Meanwhile,UScompanyMars,oneoftheworld’sbiggestmanufacturersofchocolateproducts,announcedinJanuarythatitwouldspend$1billiontohelpreducetheeffectsofclimatechange.“Thisisaworldwideissue,anditrequireseveryonetoworktogether,”Mars’spokespersonBarryParkintoldBusinessInsider.

Themessagehereisthatifwealldoourpart,wemaybeabletopreventsomeoftheworstimpactsofclimatechange.Orifwe’reunlucky,chocolatewillbecomeathingofthepast.【文章大意】本文是一篇說(shuō)明文。隨著全球氣候變暖,用來(lái)生產(chǎn)巧克力的可可樹(shù)面臨著越來(lái)越艱難的生存環(huán)境,甚至有滅絕的危險(xiǎn)。來(lái)自美國(guó)伯克利大學(xué)的研究人員和瑪氏公司正采取措施解決這一問(wèn)題。1.Whatcouldmakeithardforcacaotosurvivearoundtheequatorinthefuture?A.Theincreasedheatthere.B.Thehigherhumiditythere.C.Thedecreaseinrainfallthere.D.Themoisturelossinthesoilthere.【解析】選D。推理判斷題。根據(jù)第四段及第七段可知,世界上大部分可可樹(shù)生長(zhǎng)在靠近赤道的國(guó)家。隨著溫度的不斷上升,土壤和植物中的水分會(huì)越來(lái)越少,而降雨量的增加不足以彌補(bǔ)土壤中水量的損失。由此可以推知,將來(lái)赤道附近可可樹(shù)生長(zhǎng)艱難的原因是土壤中含水量的損失。故選D。2.Whatdoestheunderlinedword“offset”intheseventhparagraphmean?A.holdback

B.makeupforC.protect D.accept【解析】選B。詞義猜測(cè)題。根據(jù)第七段可知,隨著溫度的不斷上升,土壤和植物中的水分會(huì)越來(lái)越少,而降雨量的增加不足以彌補(bǔ)土壤中含水量的損失。所以畫(huà)線詞的意思是“彌補(bǔ)”。故選B。3.WhatwillUScompanyMarsdotohelpcacaosurvive?A.Itwillworkhardtoplantcacaoingreenhouses.B.Itwillapplygeneeditingtechnologyinplantingcacao.C.Itwillgivefinancialsupporttohelpfightclimatechange.D.Itwilldevelopcacaothatcansurviveindrierconditions.【解析】選C。細(xì)節(jié)理解題。根據(jù)倒數(shù)第三段內(nèi)容可知,為減少氣候變化的影響,美國(guó)的瑪氏公司計(jì)劃給予資金支持。故選C。4.Whatmaybethebesttitleofthistext?A.ChocolateCouldBecomeHistoryB.WorkTogethertoFightClimateChangeC.HowWeGrowCacaointheFutureD.HowCacaoPlantsAffectClimateChange【解析】選A。標(biāo)題歸納題。本文主要講述隨著全球氣候變暖,用來(lái)生產(chǎn)巧克力的可可樹(shù)面臨著越來(lái)越艱難的生存環(huán)境,甚至有滅絕的危險(xiǎn)。再結(jié)合最后一段Orifwe’reunlucky,chocolatewillbecomeathingofthepast.如果我們不幸運(yùn),巧克力會(huì)成為歷史。故A項(xiàng)概括了本文的主題。Ⅱ.完形填空
