as三、本文是一篇记叙文。讲述了作者去美国亚利桑那州当志愿者的经历。虽然饱含辛酸却也让作者收获良多，作者不仅了解了当地的环境，还与来自世界各地的人建立了一生的联系。1．B下文介绍了作者去美国亚利桑那州当志愿者的经历，故此处

表示“从我的经历来看，这个说法绝非事实”。experience经历。故选B。2．A根据第二段中的“itcostmearound$1，000...byworkingpart-time”可知，此处是指“做志愿者

并非如此昂贵以至于它只能是富人的选择”，即普通人也可以参与。choice选择。故选A。3．C根据第三段的“maintainingtrails,buildingfencesandcarryingoutprojects...”以及最后一段的“ex-nation

alparkrangers(护林者)”可知，作者应是在美国的亚利桑那州保护大自然的美。preserve保护。故选C。4．A根据最后一段的“Spending10weeksinAmerica'smostbeautifulnationalpark

sandforests”可知，作者去了美国亚利桑那州的国家公园和森林，这是一个行程。trip行程。故选A。5．C这个行程总共花费了作者约1000美元，这笔钱大部分是作者通过做兼职来支付的。inall总共。故选C。6．D参见上题解析。cover足以支付。故选D。7．C句意：放纵

自己的形象和海外志愿者项目紧紧相连。berelevantto与……相关。故选C。8．B根据本句中的转折词“However”和上文提到的“放纵自己的形象和海外志愿者项目紧紧相连”可知，此处指“这种工作有时会很艰难”。下文的叙述也描述了志愿者工作的艰难。故

选B。9．B上文提到“亚利桑那州夏天的气温远高于35摄氏度”，故此处指“如果你还要每次搬10小时50公斤重的混凝土的话，这样的气温决不宜人”。此处要用never表示否定。故选B。10．C根据上文中的“Andthentherewasthe

wildlifetodealwith”可知，和野生动物打交道让作者的性格变得坚强，还消除了作者对英国家庭中会出现的蜘蛛的恐惧。improve提高，改善。故选C。11．A参见上题解析。fear恐惧。故选A。12．D根据下文的“Proba

blytheywantto__13__thingstotheworld.”可知，此处表示“为什么大部分人做志愿者呢”。分析句子结构可知，空处在句中做for的宾语，且指“为了什么(what)”，故选D。13．

B许多人参加志愿者活动是想回馈世界，做一些力所能及的事。giveback回馈。故选B。14．D句意：但实际上，你在做志愿者的同时也获益匪浅，如同你帮助的当地社区和生态系统一样。benefit受益；获益。故选D。15．D上下文中都提到了作者从事的志愿者活动给他带来的

好处，故此处指这是一次“难忘的(unforgettable)”经历。故选D。16．C比起一般的游客，作者对当地的环境有了更深刻的“理解(understanding)”。下文的“parkrangers(护林者)whoknew__18__ofthearea's

historyandecosystem”是提示。故选C。17．B作者在从事志愿者活动时“遇见(meet)”了以前的国家公园护林者，他们非常了解这个地区的历史和生态系统。故选B。18．A参见上题解析。knowperfectlyof...意为“非常了解……”。故选A。19．C根据

下文中的“fromBelgianstoSouthKoreans”可知，此处指“最有益的是，这10周我和来自不同文化的年轻人一起度过。”culture文化。故选C。20．D前面提到“Butbestofall,my10weekswerespentvolunteeringwithyoungpeop

le”，故这里指作者离开亚利桑那州回到家时，已经和来自全世界的人建立了一生的联系。bond联系。故选D。四、本文讲述了中国科学家第一次使用由中国科学家自主研发的射电望远镜发现脉冲星，从而开启了“中国原创空间探索的新时代”。1．

known“China'sFive­hundred­meterApertureSphericalRadioTelescope”和“know”之间是被动关系，所以用过去分词做后置定语。故填known。2．opening指代前面整个事情的结果，用

现在分词做结果状语。3．wasdiscovered句子主语和“discover”之间是被动关系，since从句时态用一般过去时，所以用一般过去时的被动语态。4．in/within“在……之内”用in或within。5．tofindallowsb.todosth.允许某人做某事。6．sci

entific修饰名词用形容词。7．which先行词为FAST，在非限制性定语从句中做主语，应用which引导。8．a泛指用不定冠词，此处指“一条新道路”。9．areasarea领域，为可数名词，前面有other

修饰，所以用复数形式。10．willremain时间状语“thenext10to20years”和一般将来时态连用。五、本文是一篇说明文。研究表明对人和动物来说，做梦的一个目的是练习重要的技能，弄清楚最近所学的东西。1．B细节理解题。由第二

段最后一句可知，MichelJouvet在他的研究中发现，做梦的猫经常会练习它们所学的重要技能。故选B。2．C推理判断题。由第四段第一句可知，老鼠是动物的一种，老鼠经常做梦目的是弄清楚它们最近所学的东西。故选C。3．A细节理解题。由最后一段第二句可知，通过对动物做梦频率的对比，可以看出

老鼠做梦最频繁。故选A。4．D推理判断题。从第二、三和最后一段可知，每个研究所得出的结论，以及对问题的回答都是基于事实。故判断出作者通过展示事实来展开短文。故选D。
