10．C【分析】本文是說明文。通過描述一個與人工智能(AI)有關)特殊的版權案件，文章講述了人工智能具有創(chuàng)造力，是否未來會代替創(chuàng)造性人才的問題，最后說明人們不必擔心人工智能，而是應該考慮與人工智能的合作。6．上文“Aspecialcopyrightcasehasrecentlydrawnattentionbecauseitisrelatedtoartificialintelligence(AI).AcourtinShenzhenruledthatanewsreportwrittenbyTencent’sAIenjoyscopyrightprotection.(一個特殊的版權案件最近引起了人們的關注，因為它與人工智能(AI)有關，深圳一家法院裁定，騰訊人工智能撰寫的新聞報道享有版權保護)”說明了一件與版權有關的案件，D項“一個網(wǎng)站違反了法律，因為它未經(jīng)許可使用了這篇文章?！本唧w解釋了上文提到的案件。故選D。7．上文“Butwhatdoesitindicate?”說明一個問題，空格處應是與上文問題一致，下文“Probablynot.AIisnotyetabletowritecreativestories.(可能不是。人工智能還不能寫創(chuàng)造性的故事)”是對問題的回答，因此空格處也是問句，G項中“AI”與下文中的AI一致，“creativeworkers”與下文的“writecreativestories”一致，故選G。8．空格處是一個分句，故從A項和E項中選擇。上文“Thenewsreportmentionedaboveismainlyaboutdata.(上面提到的新聞報道主要是關于數(shù)據(jù)的)”提到了“data”與E項中的“data”一致，后半句“itisoftenusedtowritefinancialreports.(它經(jīng)常被用來寫經(jīng)濟報告)”，根據(jù)上文內容可知，it指代上文提到的AI，E項中提到“AI”，因此推斷E項“因為人工智能擅長處理數(shù)據(jù)”符合語境，故選E。9．下文“Forexample,WayneMcGregor,aBritishchoreographer（編舞）,isfamousforusingAItocreatenewdances.(例如，英國舞蹈編導韋恩·麥格雷戈(WayneMcGregor)以使用人工智能創(chuàng)造新舞蹈而聞名)”是一個使用人工智能創(chuàng)造的例子，因此推斷空格處說明人工智能可以用于其它創(chuàng)造性領域。故選B。10．上文“It’stimetostopworryingaboutifAIcanbecreative(現(xiàn)在是時候停止擔心人工智能是否有創(chuàng)造力了)”說明我們不必擔心人工智能有創(chuàng)造力，C項中的“instead”表示轉折關系，下文“weshouldfocusonhowhumansandAIcanworktogetherinwaysthatwehaveneverdreamedofbefore.(我們應該專注于人類和人工智能如何能夠以我們以前從未夢想過的方式共同工作。)”與前文是轉折關系，說明我們不用擔心人工智能的創(chuàng)造力，而是應該專注于人類與人工智能的合作。故選C。11．B

25．B【導語】這是一篇說明文，文章講述防止應用程序過度分享手機數(shù)據(jù)的方法。21．根據(jù)空前“Forstarters,downloadappsonlyfromtheAppleAppStoreorGooglePlayStore,notfromrandomwebsites.(對于初學者來說，只能從蘋果AppStore或谷歌PlayStore下載應用程序，而不能從任意網(wǎng)站下載)”可知，要從正規(guī)渠道下載應用程序，D項“這些應用程序符合大公司的質量標準”說明原因，故選D項。22．根據(jù)空前“Beforeyouacceptanapp’stermsandconditions,lookatwhatinformationit’splanningtocollectandthinktwiceifit’saskingfortoomanypermissions.(在你接受一個應用程序的條款和條件之前，先看看它打算收集哪些信息，并再三考慮它是否要求了太多的許可)”可知，本段是關于應用程序的條款和條約，G項“例如，為什么游戲應用程序需要訪問你的短信？”對上文“考慮它是否要求了太多的許可”舉例說明。故選G項。23．根據(jù)前一句“Signupusingane-mailaddressyou’vesetupjustforthingslikeapppermissionsande-mailnewsletters.(使用你為應用程序權限和電子郵件時事通訊等設置的電子郵件地址注冊)”及空后“Thisway,ifthereisasecuritybreach(缺口),yourexposureiscontainedtothingsconnectedtothataddress.(這樣的話，如果存在安全漏洞，您的暴露將包含與該地址相關的內容)”可知，要使用專門為應用程序設置的郵箱抵制，不要使用常用的郵箱地址等，這樣如果應用程序存在安全漏洞，不會曝光常用郵箱的相關內容，F(xiàn)項“不要使用你的主要電子郵件地址或社交媒體賬戶”符合語境。故選F項。24．根據(jù)下文“Thismeansalongone(atleasttencharacters)withamixtureofletters,numbers,andspecialcharacters—and,sorry,auniquepasswordforeachapp.(這意味著一個包含字母、數(shù)字和特殊字符的長密碼（至少10個字符）——對不起，每個應用程序都要有一個唯一的密碼)”可知，本段是講密碼的設置，A項“當然，要使用一個安全的密碼”符合語境，故選A項。25．下文“Goaheadandwritethemdown—juststoreyourcheatsheetinasecurelocation(notyourwalletorphonecase!).Orenlistapasswordmanagersuchas1PasswordorLastPass.(把它們寫下來——只要把你的備忘單放在一個安全的地方（不要放在錢包或手機殼里?。┗蛘呱暾堃粋€密碼管理器，例如1Password或LastPass)”是描述如何記住密碼，B項“你怎么能把它們都記住呢”符合語境。故選B項。26．E

30．D【導語】這是一篇說明文。文章主要介紹了如何利用互聯(lián)網(wǎng)來極大地擴展自己的知識。26．上文“Takepartinanonlinelanguagecourse.(參加在線語言課程。)”以及后文“Otherwebsiteslikeuniversitiesoffercomprehensive(綜合的)languagecoursesatalowprice.(其他網(wǎng)站，如大學，提供綜合語言課程的價格較低。)”可知，上文是該段的主旨，第二段都與在線語言課程相關，下文則說提供在線語言課程的大學網(wǎng)站收費低廉，可知空格處的內容是在舉例說明線上語言課程有免費的。E項中“l(fā)anguageclasses”與下文中“l(fā)anguagecourses”一致，“Some”與下文的“Others”相對應，因此E項“Someonlineeducationalresourcesofferbasiclanguageclassesforfree.(一些在線教育資源提供免費的基礎語言課程)”最符合語境。故選E。27．下文“Online,youcanuseflashcardsandworksheetsatlittle-to-nocost.Youcanalsocommunicatewithotherlanguagelearnersthroughforums(論壇).Usestudyresourcestofurtherstrengthenyourknowledgeofthelanguage,especiallyifyou’restrugglinginyouronlinecourse.(在網(wǎng)上，你可以以很少甚至是免費的成本獲得抽認卡和工作表。你也可以通過論壇與其他語言學習者互動。利用學習資源進一步加強你的語言知識，特別是如果你在網(wǎng)上課程中很吃力的話。)”可知，這里主要介紹了在網(wǎng)上如何尋找學習資源，該段主要內容是關于在網(wǎng)上尋找學習資源的建議。A項中“theInternet”與下文中“online”相對應。因此A項“TurntotheInternetforstudyresources.(上網(wǎng)尋找學習資源)”最恰當。故選A。28．上文“Listentoforeignmusicforpractice.Youmaynotbeabletotraveltoyourcountryofchoice,butyoucanlistentonativespeakers.(聽外國音樂或看外國電影來練習。你可能不能去你選擇的國家旅行，但是你可以聽以英語為母語的人說話。)”以及下文“Lookupthewordsofaforeignsong
