熱點06大數(shù)據(jù)與數(shù)字經(jīng)濟-備戰(zhàn)2023年中考英語熱點話題解讀關鍵能力(題型)強化專練(通用版)

備戰(zhàn)2023年中考英語熱點話題解讀+關鍵能力(題型)強化專練熱點06大數(shù)據(jù)與數(shù)字經(jīng)濟什么是大數(shù)據(jù)大數(shù)據(jù)（bigdata），是指無法在可承受的時間范圍內(nèi)用常規(guī)軟件工具進行捕捉、管理和處理的數(shù)據(jù)集合。在維克托·邁爾-舍恩伯格及肯尼斯·庫克耶編寫的《大數(shù)據(jù)時代》中大數(shù)據(jù)指不用隨機分析法（抽樣調查）這樣的捷徑，而采用所有數(shù)據(jù)進行分析處理。大數(shù)據(jù)的4V特點：Volume（大量）、Velocity（高速）、Variety（多樣）、Value（價值）。對于“大數(shù)據(jù)”（Bigdata）研究機構Gartner給出了這樣的定義。“大數(shù)據(jù)”是需要新處理模式才能具有更強的決策力、洞察發(fā)現(xiàn)力和流程優(yōu)化能力的海量、高增長率和多樣化的信息資產(chǎn)。根據(jù)維基百科的定義，大數(shù)據(jù)是指無法在可承受的時間范圍內(nèi)用常規(guī)軟件工具進行捕捉、管理和處理的數(shù)據(jù)集合。大數(shù)據(jù)技術的戰(zhàn)略意義不在于掌握龐大的數(shù)據(jù)信息，而在于對這些含有意義的數(shù)據(jù)進行專業(yè)化處理。換言之，如果把大數(shù)據(jù)比作一種產(chǎn)業(yè)，那么這種產(chǎn)業(yè)實現(xiàn)盈利的關鍵，在于提高對數(shù)據(jù)的“加工能力”，通過“加工”實現(xiàn)數(shù)據(jù)的“增值”。（來源：）數(shù)字經(jīng)濟發(fā)展方興未艾，更多企業(yè)邁上“云端”（中國經(jīng)濟網(wǎng)北京9月26日訊）國家統(tǒng)計局26日發(fā)布的《新動能茁壯成長新經(jīng)濟方興未艾——黨的十八大以來經(jīng)濟社會發(fā)展成就系列報告之九》顯示，我國深入實施數(shù)字經(jīng)濟發(fā)展戰(zhàn)略，不斷完善數(shù)字基礎設施，激活數(shù)據(jù)要素潛能，大力推進數(shù)字產(chǎn)業(yè)化和產(chǎn)業(yè)數(shù)字化，數(shù)字經(jīng)濟發(fā)展實現(xiàn)重大突破，為經(jīng)濟社會持續(xù)健康發(fā)展提供了強大動力。2020年，我國數(shù)字經(jīng)濟核心產(chǎn)業(yè)增加值占GDP的比重達7.8%，數(shù)字經(jīng)濟總量躍居世界第二位。信息基礎設施建設全球領先，已建成全球最大5G網(wǎng)。2021年末，我國累計建成并開通5G基站142.5萬個，占全球60%以上。數(shù)字技術與各行業(yè)加速融合，電子商務蓬勃發(fā)展，共享經(jīng)濟、平臺經(jīng)濟日益壯大?！吨袊蚕斫?jīng)濟發(fā)展報告（2022）》顯示，2021年我國共享經(jīng)濟交易規(guī)模約36881億元，比上年增長約9.2%。工業(yè)數(shù)字化轉型提速，工業(yè)企業(yè)生產(chǎn)設備數(shù)字化水平持續(xù)提升，更多企業(yè)邁上“云端”。目前，全國已培育100個以上具有行業(yè)特色和區(qū)域影響力的工業(yè)互聯(lián)網(wǎng)平臺，連接工業(yè)設備數(shù)量超過7600萬臺（套），平臺匯聚的工業(yè)APP突破59萬個。（來源：《瀟湘晨報》，2022-09-26）圾郵件spam屏幕保護screensaver桌面desktop黑客hacker木馬（一種黑客程序）TrojanHorse病毒virus博客blog寫博客的人blogger播客podcast點擊量clickrate瀏覽量/訪問量pageview漏洞bug語音視頻voiceandvideochat網(wǎng)絡課堂onlineclass群聊groupchat導航欄navigationbar一級頁面homepage/mainpage二級頁面secondarypage/subordinatepage搜索引擎searchengine自動搜索autosearch手動搜索manualsearch站點管理員sitemanager寬帶broadband帶寬bandwidth服務器server瀏覽器browser認證授權certificateauthority域名系統(tǒng)DNS--(DomainNameSystem)域名domainname以太網(wǎng)ethernet常見問題回答FAQ(frequentaskedquestions)防火墻firewall互聯(lián)網(wǎng)上的激烈爭論flamewar局域網(wǎng)，本地網(wǎng)LAN--(LocalAreaNetwork)郵件發(fā)送清單maillist網(wǎng)絡禮節(jié)netiquette端口port網(wǎng)關gateway安全認證securitycertificate遠程登陸telnet論壇BBS(BulletinBoardSystem)/forum論壇版塊board版主moderator用戶user管理員administrator發(fā)貼post回帖reply提交貼子submitpost預覽preview重置reset主題topic/thread加精addtodigest置頂stick移動move刪除delete刷新refresh登陸logon/login注銷logout一、閱讀理解1FiveyearsisarathershorttimeinthelonghistoryofChina.Butfordigital(數(shù)字的)development,alotofchangeshavetakenplaceinmanyaspectsofourlife.Nowadays,it’snormalforpeopletocommunicateonWeChat,themostpopularmobilesocialmediaplatforminChina.Peopletakelesscash(現(xiàn)金)withthembecausemostofthestoresandhotelsacceptWeChatPayandAlipay.InChina,holdingamobilephonemeanshavingtheworldinyourhands.Youcanshop,travel,communicate,havefunbyusingamobilephone,andallofthesetaskscanbecompletedwithafewfingertaps.Withoutmobilephones,lifewouldseemdull.Bytheendof2016,therewere695millionmobilephoneusersinChina,anincreaseof12percentonyear-on-yearbasis.TheaveragemobileInternetdatatrafficreached172megabytespermonth,whichwasfarmorethantheglobalaverage.Atthetwosessions(兩會),PremierLiKeqiangpointedoutthatin2017thespeedofmobilenetworkwouldbeincreasedandthecostwouldbereducedgreatly.Mobileratesfordomesticroaming(國內(nèi)漫游)andlongdistancecallswouldbecancelled(取消).Meanwhile,theTD-LTE4GcommunicationtechnologydevelopedmainlyinChinahasbeenacceptedandwidelyusedacrosstheworld.In2020,China’s5Gnetworkisinservice.IthelpsChina’smobiletelecommunicationovertake(反超)theinternationalcommunity’s.1.Peopletakelesscashwiththembecause________.A.cashisn’tusefulanymore
