关闭；takenout取出，拿出；usedup用完，耗尽。结合语境后面是买自行车，只能是没钱买了，可知选D。11．B【详解】句意：外国人晚上到达上海。考查介词。arriveat：到达小地方；arrivein：到达大地方；本句中“到达上海”是大地方，可知使用arrivein。短语atnight：“晚上，在晚上，在夜晚”，可知填at；故选B。12．B【详解】句意：我们的老师告诉我们，光传播的速度比声音快得多。在含有宾语从句的主从复合句中，当主句用了一般过去时态时，宾语从句也要用相应的过去时态。但当宾语从句表示客观真理时要用一般现在时。光传播的速度比声音快，既是客观真理。所以选B。13．C【详解】句意：在过去的2年里她取得了很大的进步。根据“inthepast2years”可知该用现在完成时，结构为have/hasdone,make的过去分词为made，所以选C。14．B【详解】句意：在政府的帮助下，贫困的孩子可以得到良好的教育。考查介词的辨析和冠词a/an区别。第一个空，“在……的帮助下”withthehelpof…，是固定短语。第二个空，泛指一个好的教育，good是以辅音音素/g/开头，用a修饰。故选B。15．D【详解】句意：——你看见我的钢笔了吗？——是的，我看见了。我刚才看见它在你的课桌上。考查一般疑问句和动词时态。根据回答“Yes,Ihave.”可知问句应是由“Have”开头的一般疑问句，因此用现在完成时“Haveyouseen”。故选D。II.补全对话。（共5小题，每小题2分，计10分。）16．E17．C18．D19．B20．A【导语】本文是一个对话，A询问B去了哪里，B向A介绍了去购物中心的经历，并说以后假期再也不去那里了，A也同意。16．根据“Ihavebeentotheshoppingcenter.”可知，应该询问去了哪里，所以E项“你去哪里了？”符合语境，故选E。17．根据“Ihavebeentotheshoppingcenter.”可知，去了购物中心，之前没有去过，C项“以前我从未去过那”符合语境，故选C。18．根据“Didyoubuyanything?”可知，此处询问是否买东西了，是一般疑问句，所以D项“没有，我什么都没买”符合语境，故选D。19．根据“Thereweretoomanypeoplethere,andIcouldn’tevenmove”可知，那里有太多的人，此处对此现象进行评价，B项“在假期间总是像那样”符合语境，故选B。20．根据“Iwillnevergothereduringpublicholidays”可知，B说“我绝不会在公共假期期间去那”，所以A项“我也不会”符合语境，故选A。=3\*ROMANIII.完形填空。（共10小题，每小题1分，计10分。）21．C22．B23．B24．B25．B26．A27．B28．C29．D30．B【分析】本文介绍了凯特和桑迪分别喜欢住在城镇和农村的原因。21．句意：他们是姐妹。考查主谓一致。主语是第三人称复数they，故be动词用are。选C。22．句意：他们现在住在城里。1.inthetown在这个城镇里，特指；

2.intown：在城里，泛指；3..inthecountry在农村，在乡下。根据下文Shelikeslivingintownverymuch.（她非常喜欢住在城里。）可知填intown；选B。23．句意：凯特比桑迪大。根据than可知，这需要使用old的比较级。old的比较级是older。选B。24．句意：凯特认为住在城里比住在乡下更有趣。根据than可知，这里需要用interesting的比较级。interesting的比较级为moreinteresting。选B。25．句意：凯特认为住在城里比住在乡下更有趣。than在此为介词，故其后用动词的ing形式。结合句意和livingintown可知填living；选B。26．句意：她认为夜晚的灯光比星星更美。根据句中lights和stars的语境可知，这里指的是“夜晚”。短语atnight：在夜晚；结合句意可知填atnight；选A。27．句意：她比桑迪更喜欢阅读和阅读。根据句中than可知，这里的副词quickly要用比较级，其比较级的构成形式为：morequickly。morequickly在此作reads的状语，意为“阅读速度更快”。选B。28．句意：她认为乡村生活很安静。考查名词辨析。A.school学校；B.city城市；C.country乡下，农村；D.town城镇。根据上文Sandylikesthecountry.（桑迪喜欢乡村。）可可知此句句意是“她认为乡村生活很安静。”故选C。29．句意：她经常帮助她姑妈工作。考查动词固定搭配。help…with是固定短语，意为“帮助……做某事”。结合句意可知填with；选D。30．句意：她还认为在乡村跑步是一件最令人兴奋的事情。动名词做主语谓语动词使用单数；“Shealsothinks”是主句，running…是宾语从句。在该宾语从句中running是主语。动词ing形式作主语视为第三人称单数，故be动词用is。选B。=4\*ROMANIV.阅读理解。（共20小题，每小题2分，计40分。）A篇：31．B32．C33．D34．A35．C【导语】本文是一篇说明文，主要介绍第七次人口普查，以及人口普查的范围和意义。31．细节理解题。根据第一段“FromNovember1sttoDecember10thin2020,Chinadiditsseventhnationalpopulationcensus…”可知，我们可以了解第7次人口普查的时间、普查的主要信息以及与过往人口普查的区别是什么，未提到人口普查由哪个部门进行。故选B。32．细节理解题。根据第二段“China’snationalpopulationcensusbeganin1953andhasbeenheldeverytenyearssincethefourthonein1990.”可知，从1953年起，人口普查是每10年一次，第4次人口普查是1990，由此推知第5次人口普查应在2000年。故选C。33．词义猜测题。根据第二段“In1953,therewereabout600millionpeopleinChina.ButChina’spopulationhasboomed.Itwasabout1.37billionin2010.”可知，1953年，中国的人口是6亿，而2010年中国的人口为13.7亿，中国的人口增长得较快；由此推知，boom在此表示“激增”。故选D。34．推理判断题。根据第三段“Forthe2020’snationalpopulationcensus,allresidentsofChinawereincludedinthecensus.ButChinesecitizenswhohadsettledabroadandforeigncitizenswhowerestayinginChinaoneitherbusinessortouristvisaswerenotcounted.”可知，2020年的人口普查中，中国所有的居民都被纳入了人口普查范围；但在国外定居的中国公民，以及持有商务或旅游签证而留在中国的外国公民不在统计之列。由此推知，2020年的人口普查包括了出国旅游的中国居民。故选A。35．细节理解题。根据第四段“Itwillhelpimproveinfrastructureandpublicservices.”可知，人口普查有助于改善基础设施和公共服务。故选C。B篇：36．A37．C38．A39．B40．B【分析】本文主要讲述了如今人口问题已经非常严重，并举例说明了一些城市的人口增长情况。36．词义猜测题。根据“Tianjin’swas7.9millionin1985.”可知，1985年天津的人口为790万，根据“In2000,itboostedto9.7million.”可推测，句意应为2000年增加到970万，所以第二段中带下划线的单词“boosted”的意思是增加，故选A。37．细节理解题。根据第二段“Lima’spopulation…butitgrewto9.1millionin2000.Tianjin’s…In2000,itboostedto9.7million.Mexicocity…Butin2000,itspopulationreached25.8million.”可知，2000年人口最多的城市是墨西哥城，故选C。38．细节理解题。根据第三段“Whatdoesthepopulationgrowthmean?Itmeansgreaterpressurefortheearth.”可知，人口增长意味着地球面临更大的压力，所以如果人口继续快速增长,地球将承受更大的压力，故选A。39．推理判断题。根据最后一段“Ifthegovernmentdoesn’ttakeanyactiontocontrolthepopulation,wewouldhaveonlystandingroombytheendofthe21stcentury.”可知，如果政府不采取任何行动来控制人口，到21世纪末我们将只有站立的空间，由此可推断，我们应该采取一些行动来控制人口，故选B。40．推理判断题。本文是关于人口的问题，所以应该在科学类的书上能看到，故选B。C篇：41．A42．C43．C44．B45．C【解析】文章主要讲了中国将进行第七次人口普查，并介绍了人口普查的作用和2020年人口普查不同于以往的地方。41．细节理解题。根据“Theyareworkingonthe7thnationalpopulationcensus.Theywillaskeachfamilyabouttheirname,age,educationandjob.”可知第七次人口普查会问人们的姓名、年龄、教育程度和工作，不会问爱好。故选A。42．推理判断题。根据“FromNov.1toDec.10in2020,ifsomeoneknocksatyourdoorandwantstoaskyousomequestions,don’tbeafraid.Theyareworkingonthe7thnationalpopulationcensus.”及“Chinahasacensusevery10years.”可知第七次人口普查在2020年，而中国每10年进行一次人口普查，由此推出第六次人口普查在2010年。故选C。43．词义猜测题。根据“Atthefirstone,therewereabout600millionpeopleinChina.NowChina’spopulationhasboomed.Itwasabout1.37billioninthe6thcensus,accordingtotheNationalBureauofStatistics(NBS).”可知第一次人口普查时中国有6亿人，第六次人口普查时中国有13.7亿人，由此可知中国的人口增长了，boomed是“增长”的意思。故选C。44．细节理解题。根据“‘Thecensusisveryimportantforeverycitizen,’saidNingJizhe,directoroftheNBS.‘Itwillhelpimproveinfrastructureandpublicservices....’”可知人口普查对每个公民来说都很重要是因为它将有助于改善基础设施和公共服务。故选B。45．段落大意题。根据“2020’scensusisdifferentfrompastonesinoneimportantway.”可知最后一段主要讲2020年人口普查与过往的人口普查的不同之处。故选C。D篇：46．C47．D48．A49．B50．A【分析】本文主要讲述了世界上人口最多的国家——中国，为了解决人口问题实施了独生子女政策，当它进行一段时间后，许多人不仅看到它的优点而且还有缺点。文中经过一番论述说明后，阐述了独生子女政策已经过时，现下需要双子女政策以解决当前和未来的问题。46．细节理解题。根据Chinaisagreatcountrywiththelargestpopulationintheworld．可知中国在世界上人口最多。故选C。47．词义猜测题。根据ordertosolvethepopulationproblem,ourgovernmentcarriedoutonechildpolicybefore.Whenitiscarriedoutforsometime,manypeoplenotonlyseeitsadvantagesbutalsodisad
