encewithprofessionalsinotherfieldstocreatenewproductsbasedonthephenomenonwecallsound.”可知，在过去，音响工程师在录音室的后室工作，但今天的许多音响专业人士正在与其他领域的专业人士分享他们的知识和经验，以我们所谓的声音现象为基础创造新产品。结合下文具体内容可知，本文着重论述了声音技术领域的发明创造。故选B。【强重难词】1.definitelyadv.清楚地，当然；明确地，肯定地2.professionaladj.专业的；职业的；职业性的3.phenomenonn.现象；奇迹；杰出的人才4.chasevt.追逐；追捕vi.追逐；追赶；奔跑5.suspect_v.怀疑；猜想n.嫌疑犯6.deafenvt.使聋；淹没7.temporarilyadv.临时地，临时8.commercialadj.商业的；营利的；靠广告收入的9.analyzevt.对…进行分析，分解（等于analyse\n1.inotherfields在其他领域2.let…getaway让离开3.pullout离开，撤离；拔出；渡过难关；恢复健康；折叠的大张插页；飞机进场重新飞起4.switchon接通，开启5.droptotheground.倒在地上;卧倒6.gocrazy发疯；疯狂【析长难句】1.Inthepast,soundengineersworkedinthebackroomsofrecordingstudios,butmanyoftoday’ssoundprofessionalsaresharingtheirknowledgeandexperiencewithprofessionalsinotherfieldstocreatenewproductsbasedonthephenomenonwecallsound.【解析】本句包含由but连接的两个并列分句。第一个分句为简单句；第二个分句为一个复杂的主从复合句。第二个分句使用了share…with这一固定结构，动词不定式短语tocreatenewproducts做目的状语，过去分词短语basedonthephenomenon做定语，定语从句wecallsound修饰thephenomenon.【译文】在过去，声音工程师在录音室的密室里工作，但今天的许多声音专业人士正在与其他领域的专业人士分享他们的知识和经验，以我们称之为声音现象的基础上创造新产品。【仿写】_____________________________________________________________________________________________________________________________________________________________________2.Directedsoundisanewtechnologythatallowscompaniestousesoundinmuchthesamewayspotlights(聚光灯)areusedinthetheater.【解析】本句中的thatallowscompaniestousesoundinmuchthesamewayspotlights(聚光灯)areusedinthetheater.是定语从句，修饰anewtechnology。【译文】定向声音是一项新技术，它可以让公司像在剧院使用聚光灯一样使用声音。【仿写】_____________________________________________________________________________________________________________________________________________________________________3.Restaurantscanofferachoiceofmusicalongwiththevariousfoodchoicesonthemenu,allowingcustomersmorecontrolovertheatmosphereinwhichtheyaredining.【解析】allowingcustomersmorecontrolovertheatmosphereinwhichtheyaredining是现在分词短语做结果状语。【译文】餐厅可以提供音乐和菜单上的各种食物选择，让顾客更多地控制他们用餐的氛围。【仿写】_______________________________________________________________________________\n______________________________________________________________________________________Passage2【真题详解】【2019全国卷1】Asdataandidentitytheftbecomesmoreandmorecommon,themarketisgrowingforbiometric(生物测量)technologies—likefingerprintscans—tokeepothersoutofprivatee-spaces.Atpresent,thesetechnologiesarestillexpensive,though.ResearchersfromGeorgiaTechsaythattheyhavecomeupwithalow-costdevice(装置)thatgetsaroundthisproblem:asmartkeyboard.Thissmartkeyboardpreciselymeasuresthecadence(节奏)withwhichonetypesandthepressurefingersapplytoeachkey.Thekeyboardcouldofferastronglayerofsecuritybyanalyzingthingsliketheforceofauser’stypingandthetimebetweenkeypresses.Thesepatternsareuniquetoeachperson.Thus,thekeyboardcandeterminepeople’sidentities,andbyextension,whethertheyshouldbegivenaccesstothecomputerit’sconnectedto—regardlessofwhethersomeonegetsthepasswordright.Italsodoesn’trequireanewtypeoftechnologythatpeoplearen’talreadyfamiliarwith.Everybodyusesakeyboardandeverybodytypesdifferently.Inastudydescribingthetechnology,theresearchershad100volunteerstypetheword“touch”fourtimesusingthesmartkeyboard.Datacollectedfromthedevicecouldbeusedtorecognizedifferentparticipantsbasedonhowtheytyped,withverylowerrorrates.Theresearcherssaythatthekeyboardshouldbeprettystraightforwardtocommercializeandismostlymadeofinexpensive,plastic-likeparts.Theteamhopestomakeittomarketinthenearfuture.1．Whydotheresearchersdevelopthesmartkeyboard?A．Toreducepressureonkeys.B．Toimproveaccuracyintyping.C．Toreplacethepasswordsystem.D．Tocutthecostofe-spaceprotection.2．Whatmakestheinventionofthesmartkeyboardpossible?A．Computersaremucheasiertooperate.B．Fingerprintscanningtechniquesdevelopfast.C．Typingpatternsvaryfrompersontoperson.D．Datasecuritymeasuresareguaranteed.3．Whatdotheresearchersexpectofthesmartkeyboard?\nA．It’llbeenvironment-friendly.B．It’llreachconsumerssoon.C．It’llbemadeofplastics.D．It’llhelpspeeduptyping.4．Whereisthistextmostlikelyfrom?A．AdiaryB．AguidebookC．Anovel.D．Amagazine【答案】1-4DCBD文章大意：主题：人与社会(科学与技术)；话题：智能键盘。本文是一篇科研报道。来自佐治亚理工学院的研究人员发明了一种智能键盘，可以通过分析用户的打字模式来判断该用户是不是安全访客。1．D解析：推理判断题。根据第二段第一句“ResearchersfromGeorgiaTechsaythattheyhavecomeupwithalow－costdevicethatgetsaroundthisproblem:asmartkeyboard.”以及第一段最后一句“Atpresent，thesetechnologiesarestillexpensive，though.”可推知，研究者研发这种智能键盘是为了降低网络安全保护技术的成本。注意题干、正确选项以及原文中一些词汇的多次呼应现象：develop与comeupwith是同义词，expensive与low－cost是反义词，cutthecost与low－cost相呼应。2．C解析：推理判断题。题干问的是“是什么让智能键盘的发明成为可能”，也就是问这一发明的核心依据是什么。根据第二段中的“Thesepatternsareuniquetoeachperson.Thus，thekeyboardcandeterminepeople'sidentities...”可知，正是因为每个人的打字模式不同，这种智能键盘就可以通过分析用户的打字力度及节奏等来判断该用户是不是安全访客，故C项符合题意。解答该题的关键是看懂题干的意思，即智能键盘的核心依据是什么。3．B解析：细节理解题。根据题干“研究者对于智能键盘有什么期望”可直接定位到最后一段的最后一句话“Theteamhopestomakeittomarketinthenearfuture.”，该团队希望在不久的将来将智能键盘推向市场，故选B项。注意：题干中的expect与原文中的hope呼应，答案选项中的consumers与原文中的market呼应。4．D解析：文章出处题。根据本文的话题“智能键盘”以及第二段中的“ResearchersfromGeorgiaTechsaythattheyhavecomeupwithalow－costdevice...”，尤其是其中的关键词researchers，low－costdevice等来推断，这篇文章是一篇科研报道，最有可能出现在杂志上。【强重难词】1．identityn.身份；同一性，一致；特性2．theftn.盗窃；偷；赃物3．fingerprintn.指纹；手印4．

ndriaSimons在接受BBC采访时表示：“把身体浸泡在冰冷的盐水中，只要你愿意，就会感觉自己与大自然融为一体，这种感觉太棒了。”)”可知，SandriaSimons认为冷水游泳使人接近大自然。故选A。\n13．细节理解题。根据最后一段“So,ifyou'reconvincedthatthisisforyou,takeadvice:approachitwithcaution,swimwithafriend,andmaybestartinthesummer,whenthewatertemperaturesarehigher!(所以，如果你确信这是适合你的，请接受建议：要小心进行，和朋友一起游泳，也许可以在夏天开始，因为水温较高！)”可知，作者的建议是安全第一。故选D。
