【语篇解读】这是一篇说明文。文章主要介绍了在古代沉积物中发现的一条微小线索揭开了格陵兰岛过去

和未来气候的大秘密。就在广阔的格陵兰冰原的西北边缘，研究人员发现了在最后一个冰河时

代幸存下来的湖泥。现在研究人员认为，格陵兰北部的冰盖经历了比之前认为的更强烈的变

暖。

【解析】推理判断题。根据第一段的Themud,andremainsofcommonfliesinit,recordtwointerglacial

periods（间冰期）innorthwestGreenland.（在格陵兰岛西北部，泥浆和常见苍蝇的残骸记录了两次间

冰期）和第二段的Althoughresearchershavelongknownthesetwoperiods—theearlyHoloceneand

LastInterglacial-experiencedwarmingintheArctic,themixofflyspeciesshowsthatGreenlandwas

evenwarmerthanpreviouslythought.（尽管研究人员很早就知道这两个时期全新世早期和最后

一次间冰期——在北极经历了变暖，但混合的蝇类表明格陵兰岛甚至比之前认为的还要热）可知,

在前两段中提到苍蝇的残骸是为了证明格陵兰岛的温度比之前认为的要高得多。故选C。

59.ThenewinformationaboutGreenlandisimportantbecause.

enoughicetoequal20feetofglobalsealevel.44NorthwestGreenlandmightfeelreallyremote,but

whathappenstothaticesheetisgoingtomattertoeveryoneineverycoastalcityaroundtheworld,“

可知，格陵兰岛覆盖了这个北极国家的80%,拥有相当于全球海平面20英尺的冰。“格陵兰西北

部可能真的感觉很遥远，但冰盖的变化将关系到世界上每个沿海城市的每个人。”故选D。

C

【语篇解读】本文是一篇说明文,介绍了荷兰艺术家达恩和他在太空垃圾实验室的团队提出了一个创意计划,

可以以壮观的方式清理太空垃圾。

61.Theword"obsolete'Xparagraph2）isclosestinmeaningto"

A.accessibleB.profitableC.floatingD.outdated

【答案】D

【解析】词义猜测题。根据画线词后的“Whentheydieout,theretheproblemofthemdriftinginouterspace,

collectinginwhatscientistscallthe"graveyardorbit."可知，当它们被废弃时，它们就会在外太空漂流,

被科学家们称为“墓地轨道”的地方会把它们收集起来，因此此处是说所有的卫星最终都在短短

几十年内被淘汰，由此可知画线词词义为“淘汰、使过时”，故D项正确。

62.Accordingtothepassage,whichsentencebestreplacesthequestionmarkinthediagram?

A.Workingsatellitescanbedamagedandastronautscanbehurt.

B.Satellitescanhelppeopletracktheweatherandfindnewlocations.

C.Thereismorejunkfloatinginspaceeachyearasnewsatellitesareadded.

D.TheSpaceWasteLabPerformancecanshowpeoplewheresatellitesarelocated.

【答案】A

【解析】细节理解题。本题实际上考的是太空垃圾的危害，根据第三段中的“Andwhenchunksofjunkcrash

intooneanother,theybreakapartintomillionsofpieces,quicklybuildingupspeedandturninginto

fast-movingobjects,whicharedangeroustooperationalsatellitesaswellasastronautsworkingonthe

InternationalSpaceStation.“可知，当大块的太空垃圾相互碰撞时，它们会分裂成数百万块，很快加速

并变成快速移动的物体,这对运行中的卫星以及在国际空间站工作的宇航员都是危险的，由此可知,

太空垃圾会损坏工作中的卫星并使宇航员受伤，故A项正确。

63.Whichofthefollowingbestsupportstheideathatspacewasteshouldbedealtwithverysoon?

A.Sentences①B.Sentence②C.Sentence③D.Sentence④

【答案】B

【解析】细节理解题。第一句话的意思是：大多数太空垃圾来自于废弃的卫星和火箭，运行正常的卫星是

信息系统的骨干，这些系统使我们的世界保持平稳运行；第二句话的意思是：太空垃圾是一个日

益严重的问题，一些科学家说，到2050年，我们将被迫完全停止发射新的航天器，包括新的卫星。；第

三句话的意思是：因此，我们必须找到一种方法来处理这些太空垃圾,达恩拍摄了一种垃圾收集装

置,其中包括一组小型航天器将大网撒入轨道，收集太空垃圾并以最高速度将其送回地球；第四句

话的意思是：但达恩不仅仅是在谈论如何解决问题,他创造了一个比这更伟大的东西。根据第二

句话句意再结合其下一句所说的“当最后一颗卫星最终报废时，全球定位系统、手机和互联网将

不再发挥作用”，这突出了处理太空垃圾的紧迫性，因此第二句话最能支持应该很快处理太空垃

圾的观点，故B项正确。

64.Whichofthefollowingmightbethebesttitleofthepassage?

A.SpaceJunkHarmsDigitalSystemsB.Artists,ProposaltoSaveSpace

C.ANewGlimpseintoOuterSpaceD.TestofWasteCollectionNets

【答案】B

【解析】主旨大意题（标题）。通读全文，特别是根据第一段中的“Daan,aDutchartist,andhisteamatSpace

WasteLabhavecomeupwithacreativeplanthatcouldclearupspacejunkinaspectacularfashion.”

可知，本文主要介绍了荷兰艺术家达恩和他在太空垃圾实验室的团队提出了一个创意计划,可以以

壮观的方式清理太空垃圾，故B项最适合做文章的标题。

【语篇解读】本文是一篇议论文。私人教育在发达国家不重视但是发展中国家大受欢迎，有些人对私人教育

的发展不高兴，他们认为私人教育加剧了不公平性，有些政府甚至阻止其发展，针对这个现象，作

者提出了看法：这种做法是错误的。人们应该欢迎私人教育，并广泛地传播它的好处。

65.Whatdoweknowaboutprivateeducation?

A.Moredevelopedcountriesenjoyit.B.Itattractsmoreandmoreinvestment.

C.Publiceducationwillreplaceitinthefuture.D.Ithashelpedgovernmentstoremoveinequality

【答案】B

【解析】细节理解题。文中原文“thisburstofenthusiasmforinvestinginprivateeducationisexcellentnewsfbr

theworld.”因此答案选择B。私人教育吸引了越来越多的投资。但是私立教育加剧了不平等，因此

D选项错误。私人教育与公立教育并存，所以答案C错误。更多的发展中国家出现了正在受益，所

以A也错误。故选B。

66.Whatdoestheunderlinedphrase“takinguptheslack“inParagraph3probablymean?

A.Fillingthegap.B.Settingtheplace.

C.Breakingthebalance.D.Avoidingtherisk.

【答案】A

【解析】词义猜测题。对划线单词进行三句读,“Wherecitiesaregrowingatunmanageablespeed,theprivate

educationistakinguptheslack.InIndiatheprivateeducationnoweducatesnearlyhalfofallchildren,

inPakistanmorethanathird,andinbothcountriesthestateeducationisshrinking."E[l度，私人教育现

在教育了将近一半的儿童,在巴基斯坦超过三分之一。公立教育萎缩，私立教育填补空白。因此答

案选择A。

67.WhyhasprivateeducationbeendevelopingrapidlyinVietnam?

A.ThepopulationinVietnamisshrinkingdramatically.

B.Itsstateeducationisworsethanotherdevelopingcountries.

C.Somepeoplewantbettereducationfortheirchildrenthanothers.

D.Thegovernmentintendsprivateeducationtoshapeyoungminds.

【答案】C

【解析】细节理解题。通过定位词Vietnam找到文中richerpeoplestillwantbetterschoolingfortheirchildren

thanthemassesget.ThusVietnam,whichhasanoutstandingstate-schoolsystemforapoorcountry,

measuredbyitsperfbmianceintheOECD'sPISAtestalsohasthefastest-growingprivateeducation.0

此原因是富裕的人们想让孩子们获得更好的教育，故答案选择C。

68.Thesentence“Butprivateschoolsalsoincreaseinequality.^^canbeputin.

A.①B.②C.③D.④

【答案】D

【解析】推理判断题。句子意思是：但是私人学校也会导致不平等。所以加入的段落应该更多会讨论私

人学校引发的不平等。所以我们找到只有第四处符合要求。Theytendtosortchildrenbyincome,

herdingricheronestowardsbetterschoolsthatwillenhancetheiralreadysuperiorlifechances.因此选

择D。

69.Whatdoestheauthoradvisegovernmentstodo?

ATrainschoolprincipals.B.Sellvoucherstochildren.

C.learnfromprivateeducation.D.Fireunderperformingteachers.

【答案】C

【解析】细节理解题。根据文中,建议写在了最后三段Governmentsshouldinsteadfocusonimprovingthe

publiceducationbymimicking（模仿）theprivateeducation'svirtues.作者认为政府应该让公立学校模

仿私立学校的好处,故选择C选项。

70.What'stheauthor'sopinionaboutprivateeducation?

A.Privateeducationshouldbebasedonstateeducation.

B.Privateeducationshouldbetargetedatwell-offfamilies.

C.Governmentsshouldpreventthespreadofprivateeducation.

D.Governmentsshouldcelebratethepopularityofprivateeducation.

【答案】D

【解析】推理判断题。最后一段作者说了Governmentsshouldstopbehavingasthoughprivateeducationwere

oneofthem.Itwill,rather,increasethechancesoffindingsolulions.因此作者的观点是，政府应该支

持私立学校的发展以找到解决问题的办法。所以答案选择D。

A.TohelpEuropeans.B.Tofindtheirassociation.

C.Toprotectunhealthyadults.D.Toreducetheriskofheartdisease.

【答案】B

【解析】细节理解题。文章第一段提出了一项研究成果：养狗可以降低患心脏病和死亡的风险。第二段

讲的是科学家们在十二年期间研究了三百四十万人，他们发现养狗的独居成年人比不养狗的独居

成年人的死亡率要低33%,也就是说，做这项研究是为了发现两者之间的联系，所以选B..

57.Whatdoestheunderlinedword“prominent”probablymeaninPara.3?

A.Universal.B.Confusing.C.Appealing.D.Important.

【答案】D

【解析】词义猜测题。根据语境可知，独居的人跟那些生活在多人口家庭里的人相比，他们患心脏病以及死

亡的风险更高。所以，作为一种保护因素，养狗对独居的人来说尤其“重要”，故选D项。
