.

A.thesocialmovement B.recyclingtechniquesC.environmentalproblems D.theimportanceofEarthDay【解析】选C。细节理解题。根据文章首段BruceAnderson说的话“Wedidn’tknowatthattimethereevenwasanenvironment,letalonethattherewasaproblemwithit,”可知当时人们不知道环境这个概念,更别说环境问题了,由此可知答案选C。【解析】选A。细节理解题。根据文章第二段中的Businesspeople,politicalleaders,universityprofessors,andespeciallymillionsofgrass-rootsAmericansaretakingpartinthemovement.可知商人,政界领导,大学教授,尤其是平民百姓们都参与了保护环境的运动,由此判断保护环境的支持主要来自草根阶层。3.WhathaveAmericansachievedinenvironmentalprotection?A.Theyhavecutcaremissionstothelowest.B.Theyhavesettledtheirenvironmentalproblems.C.TheyhaveloweredtheirCOlevelsinfortycities.D.Theyhavereducedpollutionthrougheffectivemeasures.【解析】选D。细节理解题。根据文章倒数第二段中的In1988therewereonly600recyclingprograms...andbuildingdesignshavehelpedsavealotofenergyandthereforepreventedpollution.可知回收工作的改进,先进产品或者住房设计的研制开发等都是有效地减少了污染,改善了环境,故答案选D。4.Whatisespeciallyimportantforenvironmentalprotectionaccordingtothelastparagraph?A.Education.B.Planning.C.Greenliving.D.COreduction.B(2021·贵阳高二检测)Terriblyhotweather.Pouringdownpours.Scientistshavelongsuspectedthatglobalwarmingcancauseextremeweatherevents.Nowexpertshavenumberstosupportthatidea.

.

A.itisreasonableforclimatechangetohappenB.thereisnoseriouseffectofglobalwarmingnowC.theinfluenceofglobalwarmingisgreatD.theextremeweatherhappensinsmallnumbers【解析】选C。推理判断题。根据第三段中“Thisisaconsiderablefractionofmajorweatherevents”可知,Peter认为这是一个相当大的数量,说明了全球变暖的影响是巨大的。故选C。【解析】选A。细节理解题。根据倒数第二段中的“BeforetheIndustrialRevolution,suchextremestypicallywouldhaveoccurredonlyonceinevery1,000days”和最后一段的第一句话“Butsincetheglobehasbeenwarming,suchextremesarenolongernearlyasrare”可知,未来这种极端的天气会频繁发生。故选A。【解析】选B。主旨大意题。本文主要介绍了全球变暖造成了更多极端天气的发生,因此B项符合题意。

Ⅴ.语法填空阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。

Allscientistssubscribe1.

theviewthatitishumanactivity2.

hascausedglobalwarming.Thisactivityisburningfossilfuels3.

(produce)energy.

【文章大意】这是一篇议论文。本文主要讲述了全球变暖的原因及科学家对全球变暖的不同态度。1.【解析】to。考查介词。句意:所有的科学家都同意这个观点,即:人类活动引发了全球变暖。表示“同意,赞成”,应用subscribeto。故填介词to。2.【解析】that。考查强调句型。分析句子结构可知,此处构成强调句型,对主语

humanactivity进行强调。强调句式的结构为:Itis+被强调部分+that+其余部分。故填that。3.【解析】toproduce。考查动词不定式。分析句子结构可知,空处应用动词不定式作目的状语,燃烧化石燃料的目的是产生能量。故填toproduce。4.【解析】a。考查冠词。asaresult“结果”,为固定用法。故填a。5.【解析】called。考查非谓语动词。

the“greenhouseeffect”作定语,修饰phenomenon,且phenomenon与call之间是被动关系,应用过去分词作定语,故填called。

6.【解析】cooler。考查比较级。根据语境和空后的than可知此处是进行比较,空处要用形容词的比较级,故填cooler。Ⅵ.阅读填句

Treatwaterassomethingprecious.“视水为珍宝。”切题。故选A。2.【解析】选
