【答案】ABCD

【解析】这是一篇说明文。文章主要介绍了回收玻璃生产的产品对空气和水的污染较小，而且比制造新玻

璃消耗的能源更少，文章还详细介绍了回收玻璃的步骤。

1.细节理解题。根据文章第三段“Whenglassarrivesatarecyclingplant,peopleandmachinessortitbycolor.

Similarcolorsofglassmustberecycledtogether.（当玻璃被送到回收厂时，人们和机器会根据颜色对其进行分

类。同样颜色的玻璃必须一起回收）“可知，回收玻璃的第一步是根据颜色进行分类。故选A。

2.细节理解题。根据文章第四段“GlassmanufacturersloveculletIfscheaperthantherawmaterialsthey'dneed

tomakenewglass.Italsomeltsatalowertemperature.Thatmeanstheysaveenergyduringtheproductionprocess.

（玻璃制造商喜欢碎玻璃。这比制造新玻璃所需的原材料便宜。它也在较低的温度下熔化。这意味着它们

在生产过程中节省了能源）”可知，玻璃制造商喜欢碎玻璃，因为它有助于降低成本。故选B。

3.推理判断题。根据文章最后一段"Doyourecycleathomeorschool?Whatglassproductsshouldyoubesureto

recyclewhenyou'redonewiththem?Witheveryonedoingtheirpart,recyclingglasscanmakeahugedifference

totheplanet!（你在家里或学校回收垃圾吗？哪些玻璃制品用完后一定要回收利用？每个人都尽自己的一份

力，回收玻璃可以给地球带来巨大的变化!）”可推知，作者在最后一段提出的问题是为了鼓励读者回收玻璃。

故选C。

4.主旨大意题。通读全文可知，文章主要介绍了回收玻璃生产的产品对空气和水的污染较小，而且比制造

新玻璃消耗的能源更少，文章还详细介绍了回收玻璃的步骤，因此文章主要讲的是如何回收玻璃。故“如何

回收玻璃”可以作为本文的最佳标题。故选D。

【答案】DABB

【解析】本文是一篇说明文。本文主要介绍了一项新的研究，主要研究水力发电对气候的影响，并得出结

论并不是所有水力发电都是清洁能源。

5.推理判断题。根据第二段“Theresearcherslookedatwhetherthefacilitiesbehaveasagreenhousegassinkoras

asource.Tofigurethisout,theylookedintoallthedifferentcomponentsthathelpdetermineahydropower

facility,sgreenhousegasemissions（排放）.（研究人员观察了这些设施是作为温室气体汇还是作为温室气体

源。为了弄清楚这一点，他们研究了所有有助于确定水力发电设施温室气体排放的不同组成部分。）”由此

可知研究人员是通过分析原因和结果来证明水电设施对气候的影响。故选Dc

6.细节理解题。根据第三段""Therearesomanycontributorstogreenhousegasemissionsfromhydropower一

butessentially,themajorityofgreenhousegasemissionsarisefromthereservoir（水库）itself,asvegetationand

气体排放来自水库本身，因为用于水电发电的大坝将植被和土壤淹没在水下。环境保护基金（Environmenlal

DefenseFund）的资深气候科学家、该研究的合著者丽莎•奥科（lissaOcko）说。当被淹没的植被分解时，会释

放出二氧化碳等温室气体。）”由此可知，水电排放的温室气体主要来源是植被和土壤，故选A。

7.细节理解题。根据第五段“Throughtheiranalysis,Ockoandherco-authorStevenHamburg,alsowiththe

EnvironmentalDefenseFund,discoveredthattheclimateimpactsofhydropowercoveracompleterange.（通过他

们的分析，Ocko和她的合著者StevenHamburg（也是环境保护基金的成员）发现，水力发电对气候的影响涵

盖了一个完整的范围。）”由此可知Ock。和她的合著者StevenHamburg发现水力发电对气候的影响包含各

个方面，故选B。

8.主旨大意题。根据第•段”Itisuniversallyacknowledgedthatrenewableenergysourcessuchassolar,windand

hydropowerareallmuchbetterfortheclimatethanfossilfuels.Itistrueforwindandsolar.However,thepicture

forhydropowerismorecomplicatedthanwethink.（众所周知，太阳能、风能和水力发电等可再生能源对气候

的影响都比化石燃料好得多。风能和太阳能也是如此。然而，水电的前景比我们想象的要复杂得多。）“以

及下文的研究描述，可知水电对气候的影响很多，并不一定都是绿色的，故选B。
