21、贫穷，故可推知此三角洲正在消失。故选B项。2.A 考查细节理解。由第四段中的These lakes can store four times the rivers yearly flow. The lakes are like the river basins bank accounts.save up water for not-so-rainy days可知，这些湖泊就像河流流域的”银行账户”一样可以存储大量的水。故选A项。3.考查推理判断。由最后一段的内容，尤其是The project serves as a model of how to manage rivers sustainab

22、ly(可持续地）for both people and nature可知，该项目为如何可持续地管理河流以使其同时服务于人与自然树立了榜样。由此可推知，发展（经济）的同时也要保护环境。故选D项。4.考查主旨大意。由于水坝控制水流，科罗拉多河河口三角洲变得干洞。最近工程师开启堤坝，让三角洲恢复了生机。故C项”一个让科罗拉多河河口三角洲恢复生机的项目”符合题意。故选C项。、【答案】5.D 6.B 7.B 8.C 9.C 10.D 11.B 12.C 13.A 14.D 15.A16.B 17.C 18.D 19.D【分析】受周围地势的限制，挪威的留坎小镇在每年九月底到次年三月中旬将近六个月的时间里都

23、享受不到阳光。但是，一组高科技镜面通过反射原理让小镇居民第一次感受到了冬日里的暖阳。人们聚在广场上享受着阳光，恒意地生活着。5. 根据空后的when the sun is shining和下文的We see the sky is并结合语境可知，此处指虽然小镇有近半年的时间没有阳光照射，但是当太阳照耀时，小镇的人是能看见太阳和蓝的。notice意为“看见”，符合语境。fear意为“害怕”；believe意为“相信”；hear意为“听到”。6.根据空后的but和darker可知，设空处意思与darker相反，根据首段对留坎小镇的地形描述可知，小镇在群山之中，小镇里的居民仰头可以看见蓝天，但是山谷里

24、却是阴暗的。blue意为“蓝色的”，符合语境。7.空前But为表转折的提示词，表示有变化发生。change意“改变”，符合语境。help意为“帮助”；happen意为“发生”；matter意为“有关系”8.根据空后的关键词reflect和第6空后的mirrors可知，此处表示小镇引进了一组高科技镜面。mirror意为“镜子”，符合语境computer意为“电脑”；telescope意为“望远镜”；camera意为“照相机”。9.根据上文可知，镜面系统将安装在周边山峰，从山峰将阳光反射到小镇。此处表示小镇的居民在周三收到了第一缕冬日阳光。receive意为“收到”，符合语境。remember意为

25、“记得”；forecast意为“预报”；imagine意为“想象”。10.根据第三段第一句中的a system of high-tech _was introduced 和空前的 residents of Rjukan _ their very fir ray of winter sunshine可知，此处指的是一组高科技反射镜面被投入使用。put sth to use意为“将某物投入使用”，符合语境。11.根据空前的The mirrors are controlled by a computer和空后的to turn along with the sun throughout the day

26、 and to close duri windy weather可知，电脑的作用是来控制、管理这组反射镜面的。direct意为“指挥；管理”，符合语境。forbid意为“禁止”；predict意为“预言”；follow意为“跟随”。12.根据空后的creating an area of sunlight roughly 600 square meters和第四段中的The town square可知，这组镜面将光束集中反射到小镇的中心广场，光照的面积大约为600平方米。square意为“广场”，符合语境。library意为“图书馆”；hall意为“大厅”；street意为“街道”。13.根据上

27、下文语境及设空处后的Rjukan residents gathered together可知，小镇居民齐聚在广场的时候应是有阳光出现的时候。appear意为“出现”，符合语境。return意为“返回”；fade意为“逐渐消失”；stop意为“停止”。14. 根据空后的standing there and taking_of each other可知，此处描述人们相聚在广场时热闹的场景。sit意为“坐”，符合语境。drive意为“驾驶”；hide意为“躲藏”；camp意为“宿营”。15.设空处所在句主要描述小镇居民相聚在有阳光的广场上的场景。take pictures of sb意为“给某人拍照

28、”；take notes of意为“记录”，多接物作宾语；take care of意为“照顾”；take hold of意为“握住；抓住不放”。根据语境并结合四个选项可知，A项符合语境。16.根据下文的I think almost all the people in the town were there.可知，有阳光的时候，几乎小镇上所有的居民都汇集到场上了。故可推断此处表示这个小镇广场上挤满了人。full意为“满的”，符合语境。new意为“新的”；flat意为“平的”；silent意为“寂静的”。17. 上文提到光照的面积只有大约600平方米，而空前却说小镇有3,500人，故可推断出此处表

29、示所有的居民不可能同时享受到阳光。enjoy意为“享受”，符合语境。block意为“阻挡”；avoid意为“避开”；store意为“储存”。18. 由上文可知，小镇的居民一年中有将近六个月是享受不到阳光的。sun-starved意为“缺乏阳光的”，符合语境。nature loving意为“热爱自然的”；energy-saving意为“节能的”；weather-beaten意为“饱经风霜的”。19.由上文提到的大约600平方米的照射面积不能让所有居民同时享受阳光可知，只有当居民轮流站在阳光下大家才能都享受到冬日的暖阳，从而推断出此处表示“分享”。share意为“分享”，符合语境。try意为“尝试

30、”；wait意为“等待”；watch意为“观看”。、【答案】20.are faced 21.a 22.failures 23.Looking 24.struck 25.left 27.without 28.but 29.smoothly【分析】本文为夹叙夹议类文章。作者将雨天在泥泞的道路上留下脚印作为切入点，讲述了在人生的道路上，每个遭遇挫折的人都会留下自己的脚印。20. 考查动词的时态、语态和主谓一致。根据语境可知，此处陈述的是客观事实，应用一般现在时；be faced with面对”为固定用法且主语people是集合名词，故填are faced21. 考查冠词。句中competition作

31、”比赛”讲，为可数名词，表示泛指，且其发音以辅音音素开头，故应在前面加不定冠词a。22.考查名词。分析句子结构可知，该空在句中作主语，故应填名词failure;又因为谓语动词make为复数形式，故应用failures。23.考查非谓语动词。分析句子结构可知，该空在句中作伴随状语，且look与句子主语I之间为主动关系，故应用现在分词。24.考查动词的时态。根据语境可知，此处陈述的是过去的情况，应用一般过去时。25.考查非谓语动词。分析句子结构可知，该空在句中作定语，修饰 footprints;且leave和footprints之间为被动关系，故应用过去分词。26.考查固定句型。由空后的the deeper可知，此处应该用所给词的比较级形式构成The+比较级.,the+比较级.句型。27.考查介词。一帆风顺的人生是我们都渴望的，但没有经历下雨天，我们如何才能够见到彩虹呢？故此处应填without。28.考查连词。挫折一定会放慢我们前进的步伐，但正是因为挫折，我们每前进一步才能留下印记。空处前后为转折关系，故应用but。29.考查副词。句中live为动词，应用副词修饰，故填smoothly。
