D.乙酸和乙醇发生酯化反应CH3COOH+CH3CH2 DHCH;COOCH2CH3+H2O,乙醇、乙酸、乙酸乙酯蒸气在冷凝管中遇冷，回流到三口烧瓶中，增加乙酸、乙醇的利用率，提高乙酸乙酯的产率，同时利用分水器可以做到乙酸乙酯与水的分离，故D正确：答案为D。14.A.金刚石、金刚砂同属于共价晶体，C-C键比Si-C键键长短，键能更大，故金刚石比金刚砂熔点更高、硬度更大，故A正确；B.氯化钠晶体中C1的配位数为6，氯化铯晶体中C1的配位数为8，故B错误；C.干冰为分子晶体，干冰的晶胞中CO2的堆积方式类似于面心立方最密堆积，其出现在晶胞的顶点和各个面心上，因此以1个CO2为中心，其周围最多可以有12个紧邻的CO2分子，故C正确；D.水是极性分子，CCL4是非极性分子，根据“相似相溶原理”，O3臭氧极性微弱，所以在CCL4中的溶解度高于在水中的溶解度，故D正确。15.A.由图像可知，0.1moLH2A溶液的pH=1,即H2A全部电离为HA,说明第一步电cOH )(HA-)离为完全电离，HA不水解，A错误；B.Na2A水解衡常数K=c(A2-)，结合pH=3时c(A2)=cHA),所以Kh=C(OH)=10I1,B正确：C.H2A溶液中全部电离，不存在H2A分子，则由物料守恒可知，c(A2)十c(HA)=0.1o/L,C错误；D.常温下，c(A2)c(A-)c(H)104=cHA)时，K=C(HA)=cH)-103,则A2水解衡常数K103=1011c(HA),则c(H)3,D错误；故选B。16.由流程知，甲苯与高锰酸钾在图示装置中反应生成苯甲酸钾，冷凝管能冷凝回流水蒸气、甲苯蒸汽，防止甲苯的挥发而降低产品产率；反应后混合物中含有氢氧化钾，加入有还原性的亚硫酸氢钠，还原高锰酸钾生成二氧化锰、趁热过滤、趁热洗涤后最大程度回收苯甲酸盐，加入盐酸后转变为苯甲酸，苯甲酸中含杂质氯化钾，利用苯甲酸能升华、溶解度的特点，提纯即可；(2)根据题给信息可知，苯甲酸微溶于水，故步骤I中反应完全的现象为：反应液不再分层（或无油珠）：(3)根据题意可知，随后需要加入浓盐酸，会和过量的高锰酸钾反应生成有毒的气体，且亚硫酸氢钠具有还原性可以除去高锰酸钾，故亚硫酸氢钠溶液的作用是化学答案第5页共7页

D篇主题语境：人与社会一一社会本文是议论文。文章探讨了人们应该如何看待高科技给教育带来的变革。32.D。推断。根据第一段可知，字母表的发明（书写技术的诞生）让柏拉图感到担忧，他认为这会让学者不再使用大脑记忆所学的知识。ChatGPT作为最尖端的科技发明，能够创作出与高中优秀论文水相当的文章。柏拉图对字母表的发明尚感到担忧，可推知，他更不会赞同用科技创作文章。33.C。理解具体信息。根据第三段中的Instead,they'd use it as a tool to generate criticallyexamined building blocks of essays可知，学生们将ChatGPT作为他们的研究工具，利用它生成文章的构成要素。34.B.理解具体信息。根据倒数第二段中的Plato was wrong to think that memory itself is a goal,,rather than a means for people to have facts so they can make better analyses and arguments知，柏拉图认为一切知识只是记忆而已，他夸大了记忆在知识获取中的作用。35.C。理解具体信息。根据最后一段中的but also to recognize that as more complex skillsbecome essential,,our society must fairly educate people to develop them可知，作者认为对待科技的正确做法应该是：在为被淘汰掉的技能感到遗憾的同时还要意识到我们还需掌握更加复杂的技能，而我们的社会则应该为我们提供接受等教育的机会，去获得这些技能。第二节主题语境：人与自然一一环境保护本文是说明文。文章就应如何处理打碎的体温计给出了几点建议。36.A。设空处与上一句之间是转折关系。A项中的But是表示转折关系的词。“人们使用水银体温计多年”与“水银有毒”在意义上存在转折关系。下文的avoid getting sick对该空也有提示作用。37.D。设空处与后面的内容解释说明第一句的内容。首句“检起破碎的玻璃并放在纸巾上”为本段主题句，后一句应具体解释如何去做，D项“拿一张干纸巾靠近溅出物”符合语境，D项中的paper towel与上一句中的paper towel为原词复现。38.G。设空处是对上一句的补充说明。设空处补充说明了“用纸片将水银聚集有利于对其进行清理”，上文中的small balls和sweep在G项中均有原词复现。39.「。设空处是本段的主题句。根据设空处后面的内容可知，本段主要说明了“用滴管收集水银的具体步骤”。Squeeze the bulb、Let go of the bulb和Slowly squeeze the mercury onto adamp piece of paper towel呼应了F项中Collect;F项中的eyedropper、damp和paper towels在下文中均有原词复现。40.B。设空处与上一句之间是因果关系。设空处解释了“在垃圾袋上标注‘含有水银的原因”。B项中的Therefore意为“因此”。语言知识运用第一节主题语境：人与自我一一做人与做事本文是记叙文。在“我”领养了Smores之后，Smores获得了她渴望的关注，而“我”也因Smores的到来而放慢了生活的脚步。41.C。42.D。根据上文的With all her cuteness和下文的I'd been checking the website for twoweeks,and she was still there可知，那只小猫那么可爱，“我”确定她很快就会被领养走。但“我”错了。43.B。44.C。45.A。根据上文的I checked the shelter website daily to see if the cat's photo wasstill there和I'd been checking the website for two weeks可知，当“我”再也无法抑制领养她

In my thirty year teaching profession,one of the best teachers I have ever known isMr.Rowe.I was lucky enough to teach fourth grade together with him.Mr.Rowe had endless patience and understanding and I learned so much from watchinghim.He could perform miracles,like the one he performed with Steven,one of the unhappiestkids I had ever seen.Steven couldn't stand school.He didn't like being picked last for kickball.He didn't like the kids who raised their hands and knew all the answers,and most importantly,he didn't like himself.The first day he walked into Mr.Rowe's classroom,he ignored the other students,lookingangry and annoyed,and slid into his chair,knocking a couple of textbooks onto the floor.Mr.Rowe walked over to him and touched Steven's shoulder,but Steven pulledaway.Nevertheless,Mr.Rowe welcomed him:"Hi,Steven.I'm happy you are in my class.We aregonna have a great year."Steven looked around the room as if Mr.Rowe must be mistaken.No teacher in his right mind would want Steven to be part of his classroom.So,while Mr.Roweseemed cheerful and relaxed that day of school,it seemed like Steven was angry and confused.That day after classes,Mr.Rowe chose Steven to pitch (the kickball during thebreak."Hey,Steven,Mr.Rowe commented,"You are good at pitching.Let me show youmy secret trick."Mr.Rowe taught Steven one of the tricks that not a single kid couldperform.Steven learned fast and did quite well!Everyone cheered for him!After the kickball,Steven sat as close to Mr.Rowe in classes as he could.When a questionwas asked,Steven lit up;when he knew the answer,he raised his hand;when he answered thequestion,his voice shook.However,he got the answer right!He said,with Mr.Rowe,his days ofthe fourth grade promised wonderful.It was obvious that Steven grew to love Mr.Rowe moreand more with each passing day.注意：续写词数应为50左右。Time passed quickly that year,and before we all knew it,it was the last day ofschool.
