答案以及解析第一部分阅读理解第一节A答案：1.C;2.D;3.D

解析：1.细节理解题。由第二段“...aroomhangingfromthesideofamountain...”和“You'reoverlookingtheSacredValley.”可知,这种房屋位于悬崖峭壁之上,位置险峻。

2.细节理解题。由第三段“...andalineoftrampolinesspreadingnearlyamile”可知,在这个地下坑道里排列着超过一英里长的蹦床。

3.细节理解题。由最后一段可知,这是个由二战时期的德军地堡改造成的艺术馆,因此历史学家会对此最感兴趣。B答案：1-4ACAC

解析：1细节理解题。根据第三段第二句中的Westernerslookattheeyesandthemouthinequalmeasure可知西方人对眼睛和嘴同等重视,故A项正确。

2.细节理解题。根据第五段第一句中的whiletheyobservedpicturesofexpressivefacesandputthemintocategories:happy,sad,surprised,fearful,disgusted,orangry可知参加人员被要求观察带有表情的面部图片并分类,故C项正确。

3.推理判断题。前文讲述由东西方各13人参加研究,研究者们将他们在辨别不同面部表情的图片时所表露出的面部变化记录了下来。再根据第六段最后一句OurdatasuggeststhatwhileWesterners...themouthless.可知东西方人在表达情感时的面部活动有差异,所以A项正确。

4.细节理解题。根据第六段第一句中的ItturnedoutthatEasternersfocusedmuchgreaterattentionontheeyes可知研究显示东方人更关注眼睛,故C项正确。C答案：1-4DDBB解析：1.推理判断题。根据第一段"Yesterday,peopleonthesocialmediasiteTwitterreactedwithsurpriseandhumortoareportthatclaimed,"Scientistshavetaughtspinachtosendemails."That'snotexactlytrue,butthe"news"isbasedonsomeamazingworkdonebyMIT(MassachusettsInstituteofTechnology)scientistsin2016,andit'sstillworthlearningabout.(昨天，社交媒体网站推特上的人们对一篇报道做出了惊讶和幽默的反应，该报道称，"科学家们已经教会菠菜发送电子邮件。"这并不完全正确，但这条"新闻"是基于麻省理工学院科学家在2016年做的一些惊人的工作，仍然值得了解)"以及第二段中"ScientistsatMIThavemanagedtochangeordinaryspinachplantsintonaturalsensorswhichcandetectchemicalsusedinbombs.(麻省理工学院的科学家们已经成功地将普通的菠菜植物变成了天然传感器，可以探测炸弹中使用的化学物质）"可推知，第一段提到了这份报告是为了引出科学实验的话题。故选D。

2.细节理解题。根据第四段中"Ifthewatercontainscertainchemicalsthatareusedinbombs,thesensorsintheleavesmakethenanotubesgiveoffaslightlydifferentkindoflight.(如果水中含有某种用于制造炸弹的化学物质，那么叶子上的传感器会让纳米管发出一种稍微不同的光）"可知，菠菜叶中的碳纳米管的作用是让菠菜以一种特殊的方式发光，故选D。

3.细节理解题。根据最后一段中"Thescientistsbelievethatinthefuture,suchasystemcouldgivefarmersdetailedinformationaboutthehealthofthelandandwaterontheirfarms.(科学家们相信，在未来，这样一个系统可以给农民提供关于他们农场土地和水健康状况的详细信息）"可知，科学家希望他们的系统被应用于农业。故选B。

4.主旨大意题。根据第二段"ScientistsatMIThavemanagedtochangeordinaryspinachplantsintonaturalsensorswhichcandetectchemicalsusedinbombs.Usingacheapandsmallcomputersystem,thespinachcanevensendawarningemail.(麻省理工学院的科学家们已经成功地将普通的菠菜植物变成了天然传感器，可以探测炸弹中使用的化学物质。使用一种廉价的小型计算机系统，菠菜甚至可以发送警告邮件）"结合文章还介绍了这种发明的工作方式以及未来的应用前景。可知，这篇文章主要讲的是科学家发明了可以测试炸弹的菠菜。故选B。D答案：1.A;2.B;3.C;4.D

解析：1.词义理解题。“which"指代"almost7,500.000acresofwildfiresinCaliforniaalone”,即Almost7,500,000acresofwildfiresinCaliforniaalonedemolishnearly50,000buildings.根据常识,火会摧毁建筑。A.destroy毁坏;B.cause导致;C.protect保护;Dbuilds建立。A项符合,故选A项。

2.细节理解题。根据"Itputsoutwildfiresbyitselfaftersensingextremeheatwithouthumans."可知A项错误。根据"Itcanstandtheextremeconditionwhichisahigh-temperatureenvironment.."可知C项错误。根据Unliketraditionalfireextinguishers,FACEhasamixtureofwaterandanenvironmentally-friendlyfireretardant(阻燃剂)withinit."可知D项错误。根据FACEhasamixtureofwaterandanenvironmentally-friendlyfireretardant可知B项正确,故选B项。

3.细节理解题。该小问问的是Arul此刻打算做什么。根据Arulisnowplanningtodeveloplargerunitsforspecificuseinforestapplications."(Arul现在正计划开发更大的设备,专用于森林。)"isnowplanningto"对应题干中的"intendtodo"“developlargerunitsforspecificuseinforestapplications."对应C项"DevelophugerFACEforforestapplications."可知C项正确,故选C项。

4.推理判断题。根据文章可知,Arul听说并亲历火灾后,为了帮助人们控制火灾,保护家园,年仅17岁的他就发明了FACE灭火器,该灭火器有很多优势。可以看出,Arul很聪明。此外,他还努力提高人们的火灾安全与预防意识,为防火做出了贡献。故D项符合,选D项。A项“wealthy"未体现;B项lazy与C项"selfish"错误。第二节答案：DAGBF

解析：①过渡句。these是对上一句中messagingplatforms的指代,thepopularity照应下一句中76percentofemployees...areusingemojisatwork。故D项是最佳选项。②细节句。上一句说使用表情符号可以增加幽默和感情,让意图清楚,设空处进一步讲述表情符号的功能。故选A项(使用表情符号的信息让人感觉更具有会话性)。③细节句。本段首句表明雇员的年龄范围从22到70及以上,找到一个共同的交流方式可能是个挑战。设空处具体解释应对挑战的方法。故选G项。④细节句。这一段阐明表情符号在语气中的作用。上一句为电子邮件如此令人烦恼,设空处衔接上文,甚至正式的电子邮件也会冰冷和不友好。故选B项。⑤主旨句。根据设空处位置可以推测此处为主旨句,是对文章的概括。研究表明更为友好的交流有助于建立更快乐的工作氛围。后面的并列分句说明表情符号就会产生那个积极的效果。因此,F项是最佳选项。第二部分语言知识运用第一节答案：1.D;2.B;3.A;4.C;5.A;6.B;7.C;8.A;9.D;10.B;11.C;12.B;13.A;14.D;15.C;16.D;17.A;18.D;19.B;20.C

第二节答案：①with②actually③toenter④so/and⑤amazing⑥winner⑦wasattracted⑧the⑨trips⑩confident

解析：①sharesthwithsb为固定搭配,
