20、商业领域，如国内的交通、电力传输、渔业、采矿和农业等商业和公共部门；此外，基于北斗的产品已销往多个国家和国外地区。1答案与解析：B考查词义猜测。通读第二段可知，该段主要讲了北斗卫星导航系统在中国的应用。再分析画线词所在句可知，其表示在中国注册的70%以上的手机能使用北斗信号。故B项正确。2答案与解析：C考查细节理解。通读全文可知，本文的主题句为“ChinasdomesticallydevelopedBeidouNavigationSatelliteSystemhasbeenwidelyusedinmanypublicsectorsandbusinessfieldsathomeandabroad
21、”，文章主要介绍了北斗卫星导航系统在国内外的广泛使用，故C项正确。3答案与解析：A考查推理判断。通读全文可知，本文主要介绍了我国自主研发的北斗卫星导航系统在国内外的广泛使用，据此可以判断，本文最可能摘自报纸的“科技”栏目，故A项正确。B语篇类型：说明文主题语境：人与社会技术创新太阳能电池板道路【语篇解读】该文介绍了自去年11月以来，位于荷兰北部小镇Krommenie的一条70米长的城镇主自行车道被一层用防滑涂层处理的玻璃地砖重铺了路面。尽管其造价高昂，但研究者预料当该技术进入大规模生产时，其成本会下降。4答案与解析：B考查词义猜测。根据panels后面的修饰它的非限制性定语从句的意思“铺设在混
22、凝土基座上”和本句后半部分提到的“每个单独的部分都包含一个太阳能电池”可知，panels指的应该是前面讲到的“glasstiles”，故选B。5答案与解析：D考查细节理解。根据第二段中的“Oneisthatwhenyoustartaninnovationlikethisyouwantastepthatisdoable, butstillguaranteesthatthingsareprettysafeforroadusers”可知，选择自行车道开始实验的原因在于这样做既可行又安全，故D项正确。6答案与解析：A考查细节理解。根据最后一段中的“Buttheresearcherspredicttha
23、twillcomedownwhenthetechnologyentersmassproduction”可以推断，作者认为太阳能电池板道路前景好，故选A。promising“有希望的，有前途的”；changeable“可能变化的，易变的”；impractical“不现实的”。7答案与解析：C考查推理判断。根据最后一段中的“Despitethetrialspromise, thereisstillonemajorproblemtodealwiththeinitialcostofroadconstructionusingthesolarpanelsishigherthanitisforstandar
24、dformsofsurfacing”可以推断，当前太阳能电池板道路还不适合投入正常使用，故C项正确。.完形填空语篇类型：记叙文主题语境：人与自我个人经历从着火的车中救人【语篇解读】本文讲述了DamianLanguell不顾个人安危，从着火的车中救出一位少年的故事。1答案与解析：C上一句说Languell被巨大的声音吵醒，所以他应是起床去检查(check)。2答案与解析：B根据空后的“Throughhisbedroomwindow.500yardsaway”可知，声音来自外面。downside“缺点，不利方面”；upside“好的一面，正面”。3答案与解析：D由第一段最后的“withitseng
25、ineonfire”可知，树的周围都是烟。4答案与解析：A根据下文中的“Thecar”可知，一辆汽车围绕着树的底部。5答案与解析：D根据语境并结合所给选项可推知，Languell立即(Immediately)提起几桶水跑向撞车地点。constantly“始终，一直”；obviously“明显地，显而易见”；hesitantly“犹豫地”。6答案与解析：B车几乎被分成了两半。split“使分开”。7答案与解析：A根据上文描述的车几乎被分成了两半可知，根据事故的严重情况看，本应该没有人能在这起事故中幸存(survived)下来。8答案与解析：B他的脸被压在驾驶位的侧窗上。presssth.agai
26、nststh.为固定搭配。9答案与解析：C根据语境可知，他处于极度的痛苦之中。10答案与解析：DLanguell试图用水桶里的水灭火，但是没有成功。11答案与解析：A参见上题解析。12答案与解析：B此处表示“当火苗进入前排座位时，我意识到(realized)我必须把他弄出来”。13答案与解析：C根据语境和常识可知，进入着火的车里去救人是非常危险的，故此处应是“完全不顾自己的安全”。complete“彻底的，完全的”。14答案与解析：A根据上文提到的车几乎被分成了两半可知，车已被严重损毁，想要救人只能爬进去。crawl“爬行，匍匐行进”。15答案与解析：C根据对车的损坏程度的描述可推知，此处表示
27、“就在那时我注意到他的腿伤得有多严重(bad)”。16答案与解析：DLanguell用一把随身携带的小折刀割断了(cutoff) Thompson的安全带。tearapart“撕毁，撕碎”。17答案与解析：A接下来，在车爆炸之前，他把这个少年从后车窗拉(pulled)出来，拖到了安全地带(safety)。18答案与解析：C参见上题解析。此处不能选“ground”，车辆一旦爆炸，地面并不一定安全，该选项表述不够明确。19答案与解析：BLanguell表现出了那种同感，正是这种同感驱使(drove)他去帮助这个少年。20答案与解析：D根据语境可知，此处表示“我十分同情Thompson”。onesheartgoesouttosb.“十分同情，怜悯”。
