从……以来到现在已有多久。”本题中的选项A/B的第二个空应该用since，而不用for或with，因此排除；选项C的第一个空用was，那么在since引导的从句中，应该用过去完成时。所以C不对。故选D。13．B【详解】句意：这种机器人被用来帮助人们做危险的工作。A.usedto过去常常；B.wasusedto被用来做某事；C.usedfor用于；D.wasusedfor被用于……。for是介词，因此后面跟动名词，help是动词原形，所以排除C/D；主语Thiskindofrobot与use之间存在着被动关系，因此应该用被动句。故选B。14．C【详解】句意：青少年不允许在公共场所吸烟。A为动词原形；B为主动语态；C为被动语态；D为一般过去时，主动语态。Teenagers与“allow”之间是被动关系，所以使用被动语态。allowsb.todosth.变成被动语态后为：sb.+beallowedtodosth.故选C。15．D【详解】句意：如果一个人被发现不戴头盔驾驶摩托车，他将受到惩罚。考查一般将来时的被动语态。分析句子可知，if引导的是条件状语从句，遵循“主将从现”的规则，空格所在句为主句，应用一般将来时；主语“aperson”和谓语动词punish是被动关系，应用一般将来时的被动语态，结构为willbedone。故选D。II.完形填空。16．B17．D18．C19．B20．B21．D22．A23．C24．A25．B【导语】本文是一篇记叙文，讲述了四个学生在课堂讨论上对自己未来想做什么的畅想。16．句意：他们正在讨论将来想要做什么。caringabout关心；talkingabout讨论；makingup编造；takingup占据，开始从事。根据上文“Theclassishavingameeting.”可知，是在课上讨论。故选B。17．句意：也许卖衣服对我来说是个好工作。buying买；paying支付；washing洗；selling卖。根据“Ilikeshoppingandtalkingtopeople.IthinkIcanlearnhowtodobusiness(生意).”可知，此处指将来从事卖衣服的工作。故选D。18．句意：我的兴趣是玩电脑游戏，在网上交朋友。jobs工作；ideas想法；hobbies兴趣；resolutions解决办法。根据“playingcomputergamesandmakingfriendsonline”可知，指喜欢玩电脑游戏，在网上交朋友。故选C。19．句意：我们经常通过电子邮件分享有趣的故事。at在；by通过；in在……里面；for为了。根据空后的“e-mail”可知，指通过邮件分享故事。故选B。20．句意：我想我会学习更多关于计算机的知识，制作超级智能的计算机程序。music音乐；computers电脑；books书；English英语。根据上文“makesuper-smartcomputerprograms.”可知，将来的工作与电脑有关。故选B。21．句意：我们在一起度过了很多快乐的时光。carefully认真地；luckily幸运的是；lovely可爱的；happily快乐地；根据上文“WhenIwaslittle,myparentskeptlotsofpets.”并结合句意可知，和宠物在一起很快乐。故选D。22．句意：我会通过画画和写书的方式与人们分享它们。them它们，宾格；it它；they它们，主格；you你，你们。根据“Thosestoriesstillstayinmymind.”可知，此处用“它们”代指上文提到的“故事”，跟在动词share后，用其宾格形式。故选A。23．句意：虽然我妈妈和两个姐姐都是医生，但是我不会去医院工作。Because因为；If如果；Although虽然；When当……时。“mymomandtwosistersarealldoctors,”和“Iamnotgoingtoworkinahospital.”之间是转折关系，用although引导让步状语从句。故选C。24．句意：我害怕看到病人虚弱的样子。afraidof害怕；goodwith与……相处融洽；sureabout确定；badat不擅长。根据上文“Iamnotgoingtoworkinahospital.”可知，害怕见到虚弱的病人。故选A。25．句意：我要通过每天玩我最喜欢的运动网球来保持强壮。fresh新鲜的；strong强壮的；quiet安静的；excellent卓越的。根据“byplayingmyfavoritesporttennis”可知，做运动可以变得强壮。故选B。=3\*ROMANIII.阅读理解。（共15小题，每小题2分，计30分。）A篇：26．B27．C28．A29．D30．C【导语】本文是一篇说明文，主要介绍了月球昼夜温差极大及其原因。26．推理判断题。根据第一段“Thesideofthemoontowardthesungetstwodegreeshotterthanboilingwater.Thenightsidereaches243degreesbelowzero.”可知，月球朝向太阳的一面比沸水的温度高2度，夜晚的一面达到零下243度。即月球表面要么很热要么很冷。故选B。27．细节理解题。根据第二段“Inalunareclipsetheearth’sshadowfallsonthemoon.”可知，月食时，地球的影子落在月球上。故选C。28．细节理解题。根据第二段“Thenthemoon’stemperaturemaydrop300degreesinaveryshorttime.”和第三段“Sowhenthemoongetsdark,theheatescapesquickly.Themoongetsverycold.”可知，月球的温度可能会在短时间内骤降300度；月球变暗，热量很快散失，月球变得非常冷。故选A。29．推理判断题。根据第三段“Ontheearth,therocksstoreheatfromthesun.Whenthesungoesdown,therocksstaywarm.Butthedustofthemooncannotstoreheat.”可知，在地球上，岩石储存来自太阳的热量，当太阳下山时，岩石保持温暖，但是月球的尘埃不能储存热量。由此可以推知，由于地球岩石储存温度的原因，相比月球，地球气温变化更小更慢。故选D。30．细节理解题。根据第三段“Butthedustofthemooncannotstoreheat.”可知，月球表面的尘埃不能储存热量。故选C。B篇：31．D32．C33．D34．B35．A【导语】本文描述了未来的生活，基因工程和机器人将改变我们的生活。31．段落大意题。根据第二段“Geneticengineeringmayhelpusmaketheperfecthuman.BabiesmaygrowuptoplaybasketballlikeYaoMingorlooklikeCeciliaCheung.Also,wemaybeabletobringthedeadbacktolife.Maybepeoplewillbeabletomeetandtalkwiththeirdeadfamilymembers.”可知本段讲述基因工程在未来各个领域的作用；选项D“基因工程可以帮助我们做什么。”符合本段文意。故选D。32．细节理解题。根据第四段“Perhapswewillbeabletomakecopiesofourselves,....”(也许我们能够复制自己)可知，未来可能更难区分人和机器，因为人类可能能够复制自己。故选C。33．推理判断题。根据第五段“Forexample,whenwehaveastomachache,wewillswallowananobotanditwilltravelthroughourstomach,takingavideoofwhat’shappeningthere…”(胃痛时吞下一个纳米机器人，它会拍下胃里的视频)可知，纳米机器人可以携带摄像机。故选D。34．细节理解题。根据第六段“Inthefuture,computersmayhavetheirfeelings.”可知，在未来，电脑可能会有自己的情感。故选B。35．推理判断题。根据最后一段“Perhapswewillbecomesupercouchpotatoesweighing250kg!”(也许我们将成为250公斤重的超级沙发土豆)可知，人类将来可能会变得更胖。故选A。C篇：36．B37．A38．A39．B40．D【导语】本文是一篇说明文。这篇短文主要讲述了外星人是否存在以及不同的人对外星人的看法。36．细节理解题。根据“Theanswerofsomescientistsisyes”可知，一些科学家给出了肯定的回答，也就是他们认为有外星人的存在。故选B。37．推理判断题。根据“Inordertofindaliens,theyhaveworkedhardforoverhalfacentury,butsofartheyhavefoundnothing.”可知，为了寻找外星人，他们辛苦了半个多世纪，但至今一无所获。半个多世纪也就是50多年。故选A。38．细节理解题。根据“StephenHawking,thefamousphysicist,thoughtitcouldbedangeroustoconnectaliens.”可知，著名物理学家StephenHawking认为联系外星人可能很危险。故选A。39．细节理解题。根据“Maybetheyaremuchsmarterthanus,butwhydotheywanttohurtus?”可知，他认为也许外星人比我们聪明得多，所以人们想要联系外星人。故选B。40．最佳标题题。结合全文内容，文章主要讲述了科学家在努力与外星人联系，同时也介绍了科学家对此的不同看法，因此选项D“我们是孤单的吗？”符合。故选D。IV.阅读还原。41．C42．E43．A44．D45．B【分析】这篇短文主要讲述了未来的汽车。大约40年前，美国科学家开始研发无人驾驶汽车。最新最有名的无人驾驶汽车是由谷歌公司2009年研发的。中国科学家也成功的研发出了一种无人驾驶汽车。并完成长沙到武汉的行程。无人驾驶汽车安全吗？一项最新的研究表明机器人比人类驾车安全。如果街道上只有10%的无人驾驶汽车，每年会挽救1千条生命。如果街道上90%的交通工具是无人驾驶汽车，那么一年会挽救21，700条生命。然而，无人驾驶汽车很昂贵，每辆车的造价大约10万。所以在不久的将来这种车不会非常流行。41．细节理解题。根据上文的句子Maybewecansitinacarthatcandriveitself.也许我们可以坐在一辆能自动驾驶的车里。可知，下文应该解释说明是谁开始开发无人驾驶汽车。结合所给的选项可知，选择scientistsfromtheUnitedStatesstartedtodevelopself-drivingcars(无人驾驶汽车).美国科学家开始开发无人驾驶汽车。符合语境。故选C。42．细节理解题。根据上文的句子Therearecamerasandradars(雷达)onthetopofthecar.车的顶部有摄像头和雷达。可知，下文应该解释摄像头和雷达的作用。结合所给的选项可知，选择Theyallowthecomputerinthecartodrawa3Dmapoftheenvironment.它们允许车内的计算机绘制环境的三维地图。符合语境。故选E。43．细节理解题。根据上文的句子Isaself-drivingcarsafe?自动驾驶汽车安全吗？可知，下文应该解释这种自动驾驶汽车安全的安全性。结合所给的选项可知，选择Arecentstudyshowsthatrobotsmakesaferdriversthanhumans.最近的一项研究表明，机器人比
