答案：hadbeen;wouldn'thavequarreled根据句子结构可知，if引导非真实条件状语从句，对过去情况的假设，主句应该用wouldn'thavedone结构。4．IfI________(be)therethen,she________(notquarrel)withherdeskmate.

答案：wasattacked

WangJie与attack之间存在被动关系，故用一般过去时的被动语态。5．Ididn'tknowwhyWangJie________(attack)bymanystudentswhenarrivingintheclassroom.

1．考查词性转换。修饰名词activities，应用形容词daily作定语。2．考查非谓语动词。与前面的skits构成动宾关系，故应用过去分词作后置定语。3．考查非谓语动词。此处作主语，与and后的incorporating并列，应用动名词making。4．考查动词的时态。根据句意，中国的短视频市场已经呈现了爆炸性增长，应用现在完成时。5．考查介词。后面是“5.73billionyuan”表示价值，应用介词at。6．考查固定用法。bepredictedtodosth

“预计做某事”。7．考查词性转换。修饰形容词popular，应用副词作状语。8．考查冠词。特指那些短视频，故应用the。9．考查名词。pet为可数名词，前面无限定词修饰，故应用复数pets。10．考查定语从句的引导词/连接词。修饰前面的整个句子，应用which引导非限制性定语从句。或makes和relieves为并列谓语，故用and连接也可。Ⅳ.短文改错WiththepopularityofcellphonesandInternet,someofwestudentsspendtoomuchtimeplayingwithcellphonesorcomputergames,whichisbadforourstudies.Worseisstill,wehavelittletimetocommunicatingwithourparentsandfriends.Sodowehavetimeforphysicalexercises.Howshallwedotoimprovethesituation?Allofusshouldrealizethenegativeeffectsofmodernmedia.Let'slimitourtimetoplayingwithcellphonesorcomputergames.Insteadweshouldspendmoretimeplayingsportsortalkingstraightlywithourparentsandfriends,whichhelpedusrelaxandcommunicate.课后作业Ⅰ.阅读理解A(2021·黑龙江哈尔滨市哈九中高三二模)Shiri

根据第二段最后一句中的“shedidn'thavetimetocontinuetohelpothersbyvolunteeringanddoinggood,whichbroughtheranxiety(她没有时间继续通过志愿服务和做好事来帮助别人，这给她带来了焦虑)”可知，Shiri(希里)在歌剧界感到焦虑是因为她几乎没有时间帮助别人。故选B。答案：D推理判断题。

根据第三段中的“Shebeganbygivinghamsas...andwishingthemallgoodluck.(在俄罗斯莫斯科举行的一场比赛中，她开始给其他参赛者送哈萨斯(中东好运的象征)，并祝他们好运。)”可推知，Shiri(施瑞)在莫斯科的时候为她的竞争对手送上祝福，这是她继续做好事的一种体现。故选D。2．WhatdidShiridotocontinuedoinggooddeedsinMoscow?A．Shehelpedparticipantsstandout.B．Sheaskedotherstoexchangegifts.C．Shetaughtotherstomakehamsas.D．Shesentwishestohercompetitors.答案：D词义猜测题。根据第三段中的“Thenextdayawomangaveeveryoneroses.(第二天，一位女士送给每个人玫瑰。)”可知，她的行为感染了其他人。由此可推知，contagious的意思是“有感染力的”，即在人与人之间传播开来。故选D。3．Whatdoestheunderlinedword“contagious”inParagraph3probablymean?A．Receivingpositivereactions.B．Transportingdiseasesaround.C．Beingcompetitive.D．Spreadingamongpeople.答案：C段落大意题。根据第四段中的“Shiri'sfirstgoal...andthesecondis...(Shiri的第一个目标是……第二个目标是……)”及“Thelastgoalis...(最后一个目标是……)”可推知，第四段的重点是Shiri运营视频博客的目标。故选C。4．WhatdoesParagraph4focusonaboutShiri?A．Herwaystopromoteoperas.B．Hergoalsofcuttingpollution.C．Heraimsofrunninghervlog.D．Herdreamsabouthersinging.B(2021·全国乙卷)Whenalmosteveryonehasamobilephone,whyaremorethanhalfofAustralianhomesstillpayingforalandline(座机)?Thesedaysyou'dbehardpressedtofindanyoneinAustraliaovertheageof15whodoesn'townamobilephone.Infactplentyofyoungerkidshaveoneintheirpocket.Practicallyeveryonecanmakeandreceivecallsanywhere,anytime.Still,55percentofAustralianshavealandlinephoneathomeandonlyjustoveraquarter(29%)relyonlyontheirsmartphones,accordingtoasurvey(调查).OfthoseAustralianswhostillhavealandline,athirdconcedethatit'snotreallynecessaryandthey'rekeepingitasasecurityblanket—19percentsaytheyneveruseitwhileafurther13percentkeepitincaseofemergencies.Ithinkmyhomefallsintothatcategory.MorethanhalfofAustralianhomesarestillchoosingtostickwiththeirhomephone.Ageisnaturallyafactor(因素)—only58percentofGenerationYsstilluselandlinesnowandthen,comparedto84percentofBabyBoomerswho'veperhapshadthesamehomenumberfor50years.Ageisn'ttheonlyfactor;I'dsayit'salsotodowiththemakeupofyourhousehold.GenerationXerswithyoungfamilies,likemywifeandI,canstillfinditconvenienttohaveahomephoneratherthanprovidingamobilephoneforeveryfamilymember.Thatsaid,tobehonesttheonlypeoplewhoeverringourhomephoneareourBabyBoomersparents,tothepointwhereweplayagameandguesswhoiscallingbeforewepickupthephone(usingCallerIDwouldtakethefunoutofit)．Howattachedareyoutoyourlandline?Howlonguntiltheygothewayofgasstreetlampsandmorningmilkdeliveries?篇章导读：本文是一篇说明文。文章主要介绍了澳大利亚使用座机的情况，并表达了座机终会退出我们的生活这一观点。答案：B段落大意题。根据第二段的内容可知，手机在澳大利亚非常普遍。故选B。5．Whatdoesparagraph2mainlytellusaboutmobilephones?A．Theirtargetusers.B．Theirwidepopularity.C．Theirmajorfunctions.D．Theircomplexdesign.答案：A词义猜测题。根据画线词所在句可知，调查显示，在仍然使用座机的澳大利亚人中，有三分之一的人认为其实没有必要使用座机，他们只是把座机看作一种安全保障。由此可推断，画线词concede的含义与admit相近，表示“承认”。故选A。6．Whatdoestheunderlinedword“concede”inparagraph3mean?A．Admit. B．Argue.C．Remember. D．Remark.答案：C推理判断题。根据第四段中的“84percentofBabyBoomerswho'veperhapshadthesamehomenumberfor50years”和第五段中的“Thatsaid,tobehonesttheonlypeoplewhoeverringourhomephoneareourBabyBoomersparents”可推知，生育高峰期出生的人一直在使用座机。故选C。7．WhatcanwesayaboutBabyBoomers?A．Theylikesmartphonegames.B．Theyenjoyguessingcallers'identity.C．Theykeepusinglandlinephones.D．Theyareattachedtotheirfamily.答案：B推理判断题。根据最后一段第二句“Howlonguntiltheygothewayofgasstreetlampsandmorningmilkdeliveries？”可推知，本段使用类比的方式，用煤气路灯和晨间牛奶递送服务退出我们的生活的例子，侧面说明座机终有一天会不再被使用。故选B。8．Whatcanbeinferredaboutthelandlinefromthelastparagraph?A．Itremainsafamilynecessity.B．Itwillfalloutofusesomeday.C．Itmayincreasedailyexpenses.D．Itisasimportantasthegaslight.Ⅱ.七选五(2021·浙江高考)You'vegotmail...andit'sapostcardPauloMagalhaes,a34­year­oldPortuguesecomputerengineer,lovestoopenhismailboxandfindabrightlycoloredpictureofRome'sColosseum.OrAfrica'sVictoriaFalls.OrChina'sGreatWall.__1__

Daily,‘butyoucanimaginethatafterawhile,youneverreceiveasmanyasyousend,andyourealizethatnoteveryoneisintoit.’(‘我经常给家人和朋友寄明信片，’他说，‘但你可以想象，过一段时间，你收到的明信片不会像你寄的那么多，而且你意识到并不是每个人都喜欢这样。’)”说明Paulo意识到身边的亲人和朋友不是都和他有相同的爱好，因此他也很坦然接受这个事实，因此A项(那完全没问题。)符合语境。故选A。3．E上文“Todayhishobbyhasdevelopedintothewebsite,asocialnetworkthathasgrownto575,217registeredusersin214countriesandregionssincehestartedit10yearsago.(如今，他的这个爱好已经发展成了这个社交网站。自从10年前他创建这个网站以来，已经有来自214个国家和地区的575,217名注册用户。)”是在介绍目前网站的发展状况，E项(8月5日，会员互赠的明信片数量达到3,100万张。)是在介绍该网站相关的数据。故选E。4．F上文“AscoolasitmaybetoreceiveapostcardwritteninChinese,theconceptdoesn'tworkifonedoesn'tunderstandit.(收到一张用中文写的明信片可能很酷，但如果你不理解它，这个概念就行不通。)”是举例说明外国人收到中文明信片时的问题。F项(同样地，如果你只会说中文，收到瑞典语的卡片也会减少一部分乐趣。)是举例说明中国人收到用外国语言书写的明信片时也会遇到相同的问题，承接上文，故选F。5．B上文“ManypeopleinChinahavelimitedexposuretoEnglish.(许多中国人很少能接触到英语。)”说明对某些人来说学习英语的门槛较高。下文“whohaveactuallyimprovedtheirEnglishskillsthroughtheiruseofpostcros
