【语篇解读】本文是说明文。地球上冰层的融化可能导致海平面加速上升,物种大量消失，

人类生活面临灾难。

28.Whatdoestheunderlinedword“retreated〃inParagraph1probablymean?

A.Grown.B.Reduced.

C.Formed.D.Disappeared.

画词义猜想题。由第一段的描述以及该段中的“theicehasgraduallymelted〃和

^theonlyicesheetsonEarth,slandmassesarefoundinAntarcticaandGreenland”可知，冰

逐渐融化,冰原也变小了，两万年前,欧洲、亚洲、北美洲和南美洲大局部被巨大的冰覆盖着，

而现在地球陆地上的冰原只存在于南极洲和格陵兰岛。

29.What,smostcommonpeople'sattitudetowardstheicesheets?

A.Optimistic.B.Critical.

C.Sincere.D.Unconcerned.

画观点态度题。由第二段中的

“Atfirstsight,theseremoteleft-oversfromthelastlceAgeseemoflittleimportanceformo

stofustoday^可知,乍一看,这些从冰河时代留下来的冰原对我们大多数人来说似乎意义不

大，由此可推断,大多数人并不关心冰原的存在。

30.Whatwouldhappenifthegreenhousegasescontinuetoincrease?

A.Vastamountsoflandwillbeflooded.

B.Largecitiesintheworldwilldisappear.

C.Thesealevelwilldroptoitslowestlevel.

D.Globaltemperatureswillseeupsanddowns.

解析推理判断题。由第二段中的"ourplanetiswarmingasaresultofthegreenhousegases”和

^Iftheplanetbecomeswarmer...wouldcausewidespreadfloodingoflow-lyingcoastalareas

andthreatenmanylargecities”可知，如果大气中的温室气体继续增加，地球将会变得更温暖,

冰原开始融化,海平面将会上升,这会使得低洼的沿海地区洪水泛滥,甚至会威胁到很多大城

市。

31.Whatcanweinferfromthelastparagraph?

A.Icesheetsmeltfasterthanfloatingice.

B.Themeltingoffloatingiceisn'tdamaging.

C.Seaicemeltingwillhavedisastrouseffects.

D.Spaceresearchcontributestoclimatechanges.

画推理判断题。由最后一段中的

“Iftheicedisappears,Earthislikelytobecomewarmerandmajorclimatechangescouldoccur

.Wildlifelivinginthepolarregionsmayalsobedestroyed"可知，地球上冰层的融化和消失

将会带来灾难性的后果。

【语篇解读】不久前,潜水员发现在希腊安德罗斯岛附近的爱琴海海域积累了大量的塑料

垃圾。从远处望去,潜水员仿佛看到了一个色彩缤纷、随着洋流缓缓流动的海底世界。然而，

在希腊安德罗斯岛的海床上,人们并没有发现任何植物一一取而代之的是数万吨的塑料废物，

在这里堆积如山，形成了一种“珊瑚礁〃。

32.Whatdoestheunderlinedword,it〃(Para.3)mostprobablyreferto?

A.TheAegeanSea.

B.Plasticpollution.

C.Thevolunteergroup.

D.Thewastesite.

画代词指代题。根据上文的

^Seaspollutedwithplastichavebecomeoneofthemostshockingsignsofhumandamagetothepl

anet.〃可知,此处的it指的是上文提到的塑料污染。

33.WhatisbelievedtobethestartofthepollutionoffAndros?

A.Collapseofawastesite.

B.Extremelybadweather.

C.Wastethrownawaybytourists.

D.PlasticwasteproducedbytheGreeks.

ggA

画细节理解题。根据第四段的

TheseapollutionoffAndrosisthoughttodatebackto2021,whenheavyraincausedawastesit

etocollapse.Mostofthewastefellintothesea."可知，污染的开始是垃圾场的坍塌。

34.WheredoestherubbishfinallyendupaccordingtoRoss?

A.Theoceans.

B.Inthefields.

C.Intherubbishsites.

D.Thewastetreatmentfactories.

ggA

画推理判断题。根据Ross所说的话

^Ifpeoplearewonderingwheretheirrubbishendsup,weseeiteachtimewegointothewater”

可知，垃圾最终进入了海里。

35.Whatcouldbethebesttitleforthepassage?

A.GulfOfPlasticCorals,FoundinAegeanSea

B.TheParadiseLiesintheCaribbeanSea

C.CoralReefsAreFullofEveryColor

D.WaterPollutionIsVerySerious

ggA

画主旨大意题。通读全文可知，潜水员在水下仿佛看到了一个色彩缤纷、随着洋流缓缓流动

的海底世界。但是,在希腊安德罗斯岛的海床上,人们并没有发现任何植物一一取而代之的是

数万吨的塑料废物，在这里堆积如山，形成了一种“珊瑚礁"。由此可知,A项可作为本文的标

题。

E.Withnocatsaround,theratpopulationcouldexplode

F.Allformsoflifedependonthisbalancefortheirexistence

G.Thesegaseshelpkeeptheworldfrombeingtoohotortoocold

答案与解析

【语篇解读】我们的星球总是在变化，它的系统总是在一起工作以保持某种平衡。当生态

链的任何一局部断裂时,整个生态系统就会受到威胁。

36.F上文提到“我们的星球总是在变化，它的系统总是在一起工作以保持某种平衡”，F项

“所有的生命形式为了生存都依赖于这种平衡〃可承接上文。

37.A上文提到“所有生物都通过食物链和食物网相互连接在生态系统中"，下文应是举例

说明,A项便是举例说明。

38.C根据下文所提到的内容来看,所填的句子是当生态链的任何一局部断裂时所发生的状

况,所以选C项。

39.E上文提到猫,下文提到老鼠。所以所填的是承接上下文的句子,E项“没有猫,老鼠就会

泛滥”可承接上下文。

40.B根据"Iftheeruptionisverybig..."可知，此处是以火山爆发为例子，所以选B项。

第三局部语言运用(共两节,总分值30分)

第一节(共15小题;每题1分,总分值15分)

阅读下面短文，从每题所给的A、B、C和D四个选项中，选出可以填入空白处的最正确选

项。

【语篇解读】一只从医院飞出的紫气球让即将走向生命尽头的男孩Jason和阿富汗女孩

建立起了让人感动的友谊。

41.A.doctorB.visitor

C.nurseD.friend

ggB

画由第二段的第五句可以判断这里应该用“visitor",说明Martha是Jason的第三个探视

者。

42.A.whyB.what

C.howD.because

画根据下文的“她是老师的女儿〃可知，此处表示原因,所以选because。

43.A.diagnoseB.touch

C.seeD.feel

画由后面的“deepinside〃及下一句可判断Jason能够在内心中“感受到〃他的生命即将

走到尽头,应选D项。

44.A.confirmedB.informed

C.decidedD.included

ggA

画祖母和医生交谈后大哭证实了(confirmed)他的生命即将走到尽头这一事实。

45.A.understandB.disturb

C.tellD.stop

fgc

画由上下文能推测出三位探视者和Jason并不是要好的朋友,所以Jason没有告诉(tell)他

们有关自己的情况,C项正确。

46.A.toreB.wore

C.stuckD.threw

|解析|根据apageoffihsnotebook可知,此处指“从笔记本上撕下了一页〃，所以选tore。

47.A.adventureB.experience

C.chanceD.choice
