12月联考政治试卷参考答案选择题123456789101Π1213141516ACCACBADBA BDC DDC1.【答案)A【解析】工业进步，使工人达到了革命联合；随着大工业的发展，资产阶级赖以生产和占有产品的基础本身也就从它的脚下被挖掉了。可见，资本主义生产方式孕育着否定自身的因素，社会生产力的发展决定着生产关系的变革，资产阶级的灭亡具有历史必然性。①③符合题意。②④不符合题意。2.【答案】1 C【解析】①：资本主义社会的主要矛盾是工人阶级和资产阶级之间的矛盾，阶级矛盾不可调和，不可能通过协商一致来解决，①说法错误。②：资本主义国家劳资双方围绕工资协议的斗争是工人阶级和资产阶级之间的矛盾的体现，②符合题意。美国工会是一个为自身谋福利的利益集团，。美国工会可以通过罢工等影响政府政策并争取自身利益。③说法错误。④：各地罢工层出不穷，体现了资本主义基本矛盾是资本主义社会一切冲突的总根源，④符合题意。3.【答案】C①：“十个明确对中国特色社会主义思想的核心内容作了进一步概括，①说法错误。②：生态文明思想是中国特色社会主义思想在生态文明建设领域的原创性贡献，深化了全党对社会主义建设规律的认识，②符合题意。③：生态文明思想对正确把握生态文明建设和推动生态文明思想创新具有重要意义，是为中华民族伟大复兴和永续发展提供了强大思想武器，③符合题意。④：生态文明思想形成于十八大以后的新时代，不是产生于中国共产党成立以来的生态文明建设实践中，④排除。4.【答案】A由图可知乡村消费品零售额增速较快，规模较大，乡村消费市场潜力大，正成为扩大内需的的重要力量。①正确，受疫情等因素影响，我国经济发展出现短期经济下行，使社会消费品零售总额同比增速出现短期波动，但整体经济向上态势并未改变。③正确。城乡居民社会消费品零售总额增加，表明城乡居民的生活水不断提高，但不能表明消费结构持续改善。消费结构是指各类消费支出在总费用支出中所占的比重。是一个相对值。②不能说明；乡村消费品零售额增速大于城镇，可表明城乡消费差距继续缩小。但因为影响消费的因素有多种，乡村消费品零售额增速大于城镇，不能表明农村居民收入增长速度高于城镇居民，城乡差距不断缩小，④说法不正确。5.【答案】C开征遗产税可节代际财富差距，但属于再分配注重公。A说法错误；强化税议冒可丽漏税，但与促进转

18.国家统计局最新公布数据显示，受新冠肺类疫情影响，一季度我国国内生产总值同比下降6.8%，成为改苹开放以来最低的季度增幅。此次新冠肺炎疫情严重冲击了经济全球化。全球经济缩水、市场萎缩，需求不振，投资停滞，不可近避免地对我国外贸出口、上下游产业链以及金融市场等方面造成不同程度的影响，经济面临较大的下行压力。许多经济专家表示，防控疫情和恢复经济两者本身存在一定矛盾，要严格防疫又要有序复工复产，如何统筹，走好衡木，这是一道非常难的题。有冈友指出“防控疫情应当以牺牲经济发展为代价，全面封锁国门，防止疫情从外输入”。结合材料，请你运用伟大的改革开放相关知识，对该网友的观点进行评析。（12分)19.阅读材料，回答问题。2022年10月16日上午，中国共产党第二十次全国代表大会在北京人民大会堂开幕。二十大代表、中国人民解放军航天员大队航天员王亚在“党代表通道”接受采访时说：“我们是幸运的，步入了新时代。一代代航天人接续奋斗，中国载人航天事业捷报频传、勇举高峰。”党中央作出实施载人航天工程重大战略决策以来，我国航天事业取得了举世瞩目的成就。中国航天追梦人从北斗环绕到嫦娥奔月，从神舟起航到天舟穿梭，从飞出大气层到中国空问站的建成…中国载人航天工程“三步走”发展战略最终实现。“三步走”发展战略的实现凸显了中国航天的智慧，也说明中国航天整体技术实力跃上了一个新的台阶，也是对人类科学与和事业的贡献，有助于人类和利用太空资源。伟大事业都始于梦想、基于创新、成于实干。航天逐梦的背后，是一群牧星耕宇的追梦人。他们数十年如一日，从大山深处到大海之滨，一路追随、永不言弃：从翩潮少年到白发院士，他们夫志杏斗、不胜不休…“心至苍穹外，目尽星河远。”这是中国航天人最真实的内心写照。结台材料和“实现中华民族伟火复兴的中国梦”的相关知识，分析航天人不断探索实验的过程是如何体现巾国梦的。（12分)第9次联步商·年级政治试卷（第7项1共8页)

BIn Ireland,where I am studying for a PhD in immunology()at Trinity College Dublin,although Irishis the first official language,English is actually the most widely used language.I grew up speaking Irish in a smallpocket of Ireland,in Ballinskelligs,County Kerry,where the language is still comparatively common.Much to mysurprise,I have found a practical use for it during my PhD program.In December last year,I was contacted by producers at the national Irish-language radio station.They wantedto know whether I would be interested in joining their discussion,and stressed the difficulty of finding people witha strong background in immunology who spoke Irish fluently.I have since been a guest on the show several times.Because English is the primary language of science,I hadnever considered Irish to be directly useful in my chosen major.It wasn't until I was asked to do the radio programthat I realized how important it is to have someone who can speak Irish.Talking about the science that I love,whilegetting the chance to relate important information to people who are not able to get it in English,meant a lot to me.To communicate with the public,researchers must be able to speak the language of our audience-which is notalways English.Science needs to consider the linguistic()diversity of the general population.Having peopleat all levels of academia()who speak several languages,including Irish and other less spoken languages,isimportant in bringing science to the public and can be good for science itself.24.What can we learn about Ballinskelligs?A.Many people speak Irish there.B.English is not used there.C.The author is studying for a PhD there.D.The author enjoys spending his vacation there.25.Why did a radio station contact the author?A.The author is a top expert on immunology.B.The author is good at both immunology and Irish.C.The author had a high popularity in his hometown.D.The author had a close relationship with the producers.26.What meant a lot to the author?A.Being a guest on a radio program.B.Putting science he loves into practice.C.Translating information from English into Irish.D.Spreading knowledge to Irish-speaking people.27.What does the author want to show through his experience?A.The importance of studying immunologyB.The importance of learning a second language.C.The importance of linguistic diversity in academia.D.The importance of working when studying at college.cSan Francisco's public trash cans()need to be replaced.The current design is inadequate for the city'sincreasing population and the larger number of tourists.To solve the issues,in 2018,San Francisco Public Worksofficials set out in search of a perfect trash can.However,it proved harder than they had thought.The officials had a few criteria in mind.The ideal trash can had to be durable(),and easy to empty.Itwould also have a built-in sensor to send warnings when full,cost between $2,000 to $3,000 a piece,and,mostimportantly,look good!After an extensive search failed to find a suitable off-the-shelf replacement,the committeeasked local firms to design custom trash cans.The four-year search ended on July 18,2022,with three selections.Since none of them meet all the requiredcriteria,the officials have turned to the city's residents for help.英语第4页（共8页）

于水得到盐酸，所以液面上方氧气体积分数增加，D正确。飞【会案)B【解析】钙离子用碳酸根离于近淀，线离子用氢氧根离子沉淀，责酸根离子用领离子沉淀，过滤要放在所有的沉淀操作之后，加碳酸钠要放在加氯化钡之后，可以将过量的领离子沉淀，据此分析。镁离子用氢氧根离子沉淀，加入过量的氢氧化钠可以将镁离子沉淀，疏酸根离子用钡离子沉淀，加入过量的氯化钡可以将硫酸根离子沉旋，至于先除镁离子，还是先除硫酸根离子都行，钙离子。用碳酸根离子沉淀，除钙离子加人碳酸钠转化为沉淀，但是加入的碳酸钠要放在加入的氧化钡之后，这样碳酸钠会除去反应利余的氯化钡，离子都沉淀了，再进行过滤，最后再加入盐酸除去反应剩余的氢氧根离子和碳酸根离子，所以正确的顺序为：③加过量的氯化钡溶液，除去硫酸根离子BaCk+NaSO,BaSO,1+2NaCi:②加过量的氢氧化钠溶液，除去MgCb,主要反应3MgCh+2 NaOH-Mg(Om2+2NaC1,④加过量的碳酸钠溶液，除去Ca2和Ba:aCo,+CaCh=Caco,+2NaC,NaC0 BaCk-BaCO,+2NaC:①过滤：再加适量盐酸.除去迁量的NaOH和Na2C0HCH+NaOH-NaC1HO、2HCaC0,2NaC+H20iC021,蒸发溶液，析出aC晶体，答案选D。【点晴】本题的易错点是碳酸钠要放在加入的氯化钡之后，这样碳酸钠会除去反应剩余的氯化钡，需要注意除杂设计时不要入新的杂质，操作简便，例如过滤放在所有离子沉淀完之后。养8【答案】B【解析A.金属钠具有强还原性，与硫酸铜溶液反应时，先与溶液中的水反应，不能置换制取金属铜，故A错误；B.碳酸氢钠和气气反应且碳酸氢钠碱性较弱，氯气制备工厂若发生泄漏时，因此可用NHCO溶液浸湿软布蒙住口鼻，由于氯气密度比空气大，因此往高处撤离，故B正确：OC.02自身并不含有氧分子，过氧化钠能与人呼吸产生的二氧化碳和水分别反应生成氧气，常用作呼吸面具供氧剂，故C错误D纯净的氢气在氯气中燃烧发出苍白色火焰，故D错误。日9.【答案】D,【解析上焰色试验没有新物质生成，是物理变化，A错误：做焰色试验时用盐酸洗涤铂丝，氯化物熔点较低，加热能除掉xB错误：焰色试验不是所有金属的性质，一般只有外层电子数比较少的容易产生焰色，C错误：钠元素的焰色为黄色，透过蓝色钴玻璃观察钾元素焰色试验的颜色为紫色，可排除钠元素黄色火焰的干扰，D正确。10.【答案】D【解析】A,由发生的反应可知反应1原理：CO2+NH+NaC+H20三NaHCO3+NHC故A正确；B碳酸氢钠溶解度较小，但仍有部分可溶解，电离出HCO,故B错误；C向饱和氯化钠溶液中先通入足量的氨气，使溶液皇碱性易吸收更多二氧化碳，故C正确，D、煅烧碳酸氢钠固体不能在蒸发皿中进行，敌正确：答案选B。11.【答案】C【解析】A项，BrC1与Ca(OiH反应的化学方程式为：·2BrCl+2Ca(OH),=CaCh+Ca(B0)2+2H0,产物有CaC2、Ca(BrO)2和H0,错误；B项，BrCl与水反应的化学方程式为：BCI+H0=HC1+HB0,反应中无化合价改变，不是氧化还原反应，水既不是氧化剂也不是还原剂，错误；C项，BC具有较强的氧化性，与Br:相似，可与碘化钾反应生成单质碘，能使湿润的淀粉碘化钾试纸变蓝，正确；D项，由于2Fe十3B2=2FeBr,BrCl能将Fe氧化成Fe3,故BrC1与铁反应公岩的化学方程式为：2FPe+3BCI=EeB十FeC,错误。黑过，类代当甘司家察事园亮12【答案】B【解析】A.盐酸属于混合物，故A错误；B.氢氧化钠、食盐水、氯化铵、二氧化硫分别属于纯净物、混合物、电解质以及非电解质，故B正确：C,铜属于单质，不屑于电解质联酸钙(6页)第2页
