参考答案及解析：第一部分第一节A【文章大意】本文是一篇应用文,介绍了三款手机应用。1.D细节理解题。根据Habitica部分中的“Habiticaturnsthegoalofforminggoodhabitsintoagame,withitsowncharactersandscoring.(Habitica将养成良好习惯的目标变成了一款游戏,拥有它自己的角色和得分。)”可知Habitica能够帮助你养成好的习惯,故选D项。2.C细节理解题。根据SmokeFree部分中的“…andsomeadviceontechniquesforgivingupsmoking.”可知,SmokeFree可以为你提供戒烟的建议,故选C项。3.B推理判断题。文中提到的三款应用:Habitica可以帮助你养成好的习惯;SmokeFree可以帮助你戒烟;MyFitnessPal可以为你提供健身的建议。由此可知,这三款应用都很实用,故选B项。B【文章大意】本文是一篇记叙文,讲述了作者是如何对智能手机上瘾的,智能手机如何影响了作者的生活,以及作者现在戒掉手机瘾过上了正常生活的经历。同时作者告诫读者要深入地思考一下自己使用手机的习惯,重新评估一下你让它在生活中扮演了多么重要的角色。4.C句意猜测题。根据第二段中的“Accordingtoastudy,theaverageAmericanspendsfivehoursadayonsmartdevices(装置)andabout2.5ofthosehoursarespentonsocial,messaging,mediaandentertainmentapps.”可知,一项研究表明,美国人平均每天花5个小时在智能设备上,其中大约2.5个小时花在社交、信息、媒体和娱乐应用上。由此判断出第二段中“我不是一个人”的意思是:有很多像他一样的美国人。故选C项。5.B推理判断题。根据第三段中的“It'shardtoexplainwhentheloveandjoyIfeltformyiPhoneturnedintodependency.”可知,作者对手机产生了依赖。后面句子中详细地从睡眠、天气、导行、查看邮箱这几个方面说明了作者深陷智能手机之中。所以从第三段可知,作者对他的手机上瘾了。故选B项。6.D段落大意题。根据第四段中的“Whilespendingtimewithfamily,I'dstareintoasmallscreenonmylapinsteadofbeinginvolvedincommunicatingwithmylovedones.Atwork,myproductivitylevelsdropped.Andthen,myfour-yearrelationshipcametoanend.”可知,和家人在一起的时候,作者会盯着手机屏幕看,却不和他爱的人交流。在工作中,作者的工作效率在下降。然后,四年的恋爱关系宣告结束。因此第四段主要讲了作者的生活受到了怎样的负面影响。故选D项。7.B推理判断题。根据最后一段中“Ihopeyou'lltakeadeeplookatyourownphonehabitsandreevaluatehowimportantaroleyouarelettingitplayinyourlife.(我希望你们深入地思考一下自己使用手机的习惯,重新评估一下你让它在你生活中扮演了多么重要的角色。)”可判断出,作者在最后一段建议人们合理使用手机,故选B项。C【文章大意】本文是一篇说明文,向我们介绍了一些如何在火星上种植蔬菜的研究。8.D细节理解题。根据第一段中的“NASAsaidtherecouldbeaproblembecauseMarsdoesn'thavesoilthatisgoodforgrowingthings,whichjusthasreddust.”可知,在火星上种植植物很困难,主要是因为没有合适的土壤,故选D项。9.A推理判断题。根据第二段中的“Theyhaveusedaspecialsoilmadeofcrushedvolcanicrockbecauseitcontainsnonutrientsororganicmaterials,whichissimilartothesoilonMars.”可知,他们用了一种特别的由火山岩制成的土壤,这种土壤没有养分,没有有机物,和火星上的土壤类似。由此可知,火星上的土壤没有养分,故选A项。10.D推理判断题。根据第二段中的“DiscoveriesmadeintheseEarth-based‘Martiangardens’willpavethewayforthefuturestudiesandtechnologydevelopmentintermsofreliable,efficientfoodproductionalongwayfromEarth.”可知,这些以地球为基础的“火星花园”中所取得的发现,将为未来在远离地球的地方进行可靠、高效的粮食生产方面的研究和技术发展铺平道路,故选D项。11.C细节理解题。根据第二段中的“Theysaidthelettucetastednormal,butithadweakerrootsandtooklongertogrow.”可知,在实验中,莴苣需要更长的时间才能培育出来,故选C项。D【文章大意】本文是一篇议论文。文章讲述的是床应是睡觉的地方,可是现在有些人喜欢在睡之前躺在床上看iPad,并通过阐述睡前在床上阅读电子书对人们身体的影响,侧面呼吁人们睡前不要在床上看电子书。12.B细节理解题。根据第二段中“Forfivedaysinarow,thesepeoplereadeitherapaperbookoraniPadforfourhoursbeforesleep.Theirsleeppatternsweremonitoredallnight.(这些人连续5天在睡前阅读4个小时书籍或看4个小时iPad。他们的睡眠模式整个晚上都被监测。)”可知,在CharlesCzeisler的实验中,这组人被要求监测整个晚上的睡眠模式,故选B项。13.C推理判断题。根据第三段中“WhenthepeoplereadtheiPadascomparedtothepaperbooks,theyfeltlesssleepyatnightandlessactivethefollowingmorning.(与阅读纸质书相比,当人们阅读iPad时,他们晚上不那么困倦,第二天早上也不那么活跃。)”可知,第二天早上,阅读iPad的人可能会变得没那么精力充沛,故选C项。14.C推理判断题。根据最后一段中“However,softwarehasbeendevelopedthatcanreducesomeofthebluelightfromthescreensofphonesandcomputers,andtherearealsoglassesthataremadetoreduceshortwavelengths.(然而,有一种软件已经被开发出来,可以减少手机和电脑屏幕上的一些蓝光,还有一种眼镜可以减少短波波长。)”可知,最近开发的特殊软件可以减少夜间电子阅读对人们造成的危害。故选C项。15.A主旨大意题。通读全文尤其是文章第一段内容可知,文章讲述的是床是睡觉的地方,可是现在有些人喜欢在睡之前躺在床上看iPad,并通过阐述睡前阅读电子书对人们身体的危害,侧面呼吁人们睡前不要在床上看电子书,因此A项能概括文章大意。第二节【文章大意】本文是一篇说明文,介绍了社交媒体的广泛传播在很多方面改变了青少年的生活。16.F根据空前句“AstudyconductedbytheUSPewResearchCentreshowedthat92percentofteenagersgoonlinedaily.(美国皮尤研究中心的一项研究表明,92%的青少年每天上网。)”可知,此处提到了青少年上网的问题。F项(社交媒体的广泛传播,几乎改变了青少年生活的方方面面。)承接上文,符合文意。17.G根据空后“BethKaplanfromIllinoismeetsherlong-distancefriendthroughsocialmedia.HecurrentlylivesinScotland,butthey'restillabletofrequentlycommunicatewitheachother.(来自伊利诺伊州的贝丝·卡普兰通过社交媒体结识了她的异地朋友。他目前住在苏格兰,但他们仍能经常交流。)”可知,社交媒体可以让人们和其他地方的人交朋友。G项(然而,一些人认为社交媒体让人们更容易与来自任何地方的任何人建立关系。)符合文意。18.D根据空后的“The19-year-oldEssenaO'NeillannouncedonthesocialnetworkingserviceInstagramthatshewasquittingsocialmediabecauseitmadeherunabletostopthinkingaboutappearingperfectonline.(19岁的埃塞纳·奥尼尔在社交网络服务软件Instagram上宣布,她将退出社交媒体,因为这让她无法停止思考如何在网上表现得完美。)”可知,社交媒体改变了青少年看待自己的方式。故D项(社交媒体的兴起改变了青少年看待自己的方式。)符合文意。19.E根据空后句“Teenagerswhogetharmfulcommentscan'thelpbutfeelhurt.(受到恶意评论的年轻人会不由自主地感到受伤。)”可知,负面的评论会对青少年造成伤害。E项(不好的评论也会对青少年的自尊造成很大的伤害。)符合文意。20.A根据下文叙述的社交媒体可以帮助人们以一种前所未有的方式向世界展示自己和自己的才能可知,社交媒体给人们打开了新的大门。A项(打开新的门。)符合文意。第二部分第一节【文章大意】本文是一篇记叙文,讲述了法国人BaptisteDubanchet为了引起人们对浪费食物的重视,骑着自行车穿越欧洲,完全靠丢弃的食物生存的事情。21.A根据下文“…survivingentirelyondiscarded(丢弃的)food…”可知,这个法国人完全靠吃垃圾中的食物生存。garbage-eating吃垃圾的;sports-loving爱好体育的;food-wasting浪费食物的;law-breaking破坏法律的。22.D虽然餐馆每年扔掉大量的食物,但由于垃圾容器上锁、卫生规定或商业政策,很多食物仍然难以接近。store存储;cook做饭;shopfor购买某物;throwaway扔掉。23.A根据“…itremainsinaccessible…”可知,这里的意思是指装垃圾的容器被上锁。locked上锁的;damaged被损坏的;connected连接的;abandoned被抛弃的。24.A句意:由于法律原因,大多数餐馆都有禁止分发食物残渣的政策。reason原因;right权利;fee费用;aid援助。25.B参考上题句意。begfor乞求;giveaway分发;hide隐藏;cause造成。26.D上文说由于法律原因,大多数餐馆都有禁止分发食物残渣的政策。故这里意思是有些人甚至冒着失业的风险给他食物。do做;keep保持;accept接受;risk冒……的风险。27.C特别有趣的是各个城市对Dubanchet事件的态度。hardly几乎不;usually通常;particularly特别是;merely仅仅。28.A根据空后“…whilethemostdifficultwastheCzechtownofPilsen.”可推知,这里的意思是柏林是最容易给他食物的,与空后形成对比。easiest最容易的;nearest最近的;biggest最大的;richest最富有的。29.C在那里,他必须在大约50家不同的商店或餐馆询问,才能找到食物。work工作;shout呼喊;ask询问;jump跳跃。30.D句意:当你考虑到从法国骑自行车到波兰所需要的高强度运动时,挑战就更加严峻了。competition竞赛;conversation会话;conflict冲突;challenge挑战。31.C句意参考上题。adequate充足的;rewarding有益的;demanding要求高的;suitable适当的。32.D句意:我必须迅速得到食物,因为骑了那么久自行车,我累了,我需要能量。again再一次;alone独自地;later后来;fast迅速地。33.B根据“…becauseafterallthebikingIamtired…”可知,“我”需要能量。spirit精神;energy能量;time时间;effort努力。34.A根据“Th
