（2024·北京·高考真题试卷）The ntin that we live in smene else’s vide game is irresistible t many. Searching the term “simulatin hypthesis” (模拟假说) returns numerus results that debate whether the universe is a cmputer simulatin — a cncept that sme scientists actually take seriusly. Unfrtunately, this is nt a scientific questin. We will prbably never knw whether it’s true. We can, instead, use this idea t advance scientific knwledge.
The 18th-century philspher Kant argued that the universe ultimately cnsists f things-in-themselves that are unknwable. While he held the ntin that bjective reality exists, he said ur mind plays a necessary rle in structuring and shaping ur perceptins. Mdern sciences have revealed that ur perceptual experience f the wrld is the result f many stages f prcessing by sensry systems and cgnitive (认知的) functins in the brain. N ne knws exactly what happens within this black bx. If empirical (实证的) experience fails t reveal reality, reasning wn’t reveal reality either since it relies n cncepts and wrds that are cntingent n ur scial, cultural and psychlgical histries. Again, a black bx.
S, if we accept that the universe is unknwable, we als accept we will never knw if we live in a cmputer simulatin. And then, we can shift ur inquiry frm “Is the universe a cmputer simulatin?” t “Can we mdel the universe as a cmputer simulatin? ” Mdelling reality is what we d. T facilitate ur cmprehensin f the wrld, we build mdels based n cnceptual metaphrs (隐喻) that are familiar t us. In Newtn’s era, we imagined the universe as a clck. In Einstein’s, we uncvered the standard mdel f particle (粒子) physics.
Nw that we are in the infrmatin age, we have new cncepts such as the cmputer, infrmatin prcessing, virtual reality, and simulatin. Unsurprisingly, these new cncepts inspire us t build new mdels f the universe. Mdels are nt the reality, hwever. There is n pint in arguing if the universe is a clck, a set f particles r an utput f cmputatin. All these mdels are tls t deal with the unknwn and t make discveries. And the mre tls we have, the mre effective and insightful we can becme.
It can be imagined that cmparable t the prcess f building previus scientific mdels, develping the “cmputer simulatin” metaphr-based mdel will als be a hugely rewarding exercise.

BMF is an indr garden system. It can be set up fr a family. Additinally, it culd serve a larger audience such as a hspital, restaurant r schl. The innvative design requires little effrt t achieve a reliable weekly supply f fresh greens.
Specifically, it’s a farm that relies n new technlgy. By cnnecting thrugh the Clud, BMF is remtely mnitred. Als, there is a cnvenient app that prvides grwing data in real time. Because the system is autmated, it significantly reduces the amunt f water needed t grw plants. Rather than watering rws f sil, the system prvides just the right amunt t each plant. After harvest, users simply replace the plants with a new pre-seeded pd (容器) t get the next grwth cycle started.
Mrever, having a system in the same building where it’s eaten means zer emissins (排放) frm transprting plants frm sil t salad. In additin, there’s n need fr pesticides and ther chemicals that pllute traditinal farms and the surrunding envirnment.
BMF emplyees live ut sustainability in their everyday lives. Abut half f them walk r bike t wrk.

（2024·全国·高考真题试卷）Is cmprehensin the same whether a persn reads a text nscreen r n paper? And are listening t and viewing cntent as effective as reading the written wrd when cvering the same material? The answers t bth questins are ften “n”. The reasns relate t a variety f factrs, including reduced cncentratin, an entertainment mindset (心态) and a tendency t multitask while cnsuming digital cntent.
When reading texts f several hundred wrds r mre, learning is generally mre successful when it’s n paper than nscreen. A large amunt f research cnfirms this finding. The benefits f print reading particularly shine thrugh when experimenters mve frm psing simple tasks — like identifying the main idea in a reading passage — t nes that require mental abstractin — such as drawing inferences frm a text.
The differences between print and digital reading results are partly related t paper’s physical prperties. With paper, there is a literal laying n f hands, alng with the visual gegraphy f distinct pages. Peple ften link their memry f what they’ve read t hw far int the bk it was r where it was n the page.
But equally imprtant is the mental aspect. Reading researchers have prpsed a thery called “shallwing hypthesis (假说)”. Accrding t this thery, peple apprach digital texts with a mindset suited t scial media, which are ften nt s serius, and devte less mental effrt than when they are reading print.
Audi (音频) and vide can feel mre engaging than text, and s university teachers increasingly turn t these technlgies — say, assigning an nline talk instead f an article by the same persn. Hwever, psychlgists have demnstrated that when adults read news stries, they remember mre f the cntent than if they listen t r view identical pieces.
Digital texts, audi and vide all have educatinal rles, especially when prviding resurces nt available in print. Hwever, fr maximizing learning where mental fcus and reflectin are called fr, educatrs shuldn’t assume all media are the same, even when they cntain identical wrds.
13．What des the underlined phrase “shine thrugh” in paragraph 2 mean?
A．Seem unlikely t last.B．Seem hard t explain.
C．Becme ready t use.D．Becme easy t ntice.
14．What des the shallwing hypthesis assume?
A．Readers treat digital texts lightly.B．Digital texts are simpler t understand.
C．Peple select digital texts randmly.D．Digital texts are suitable fr scial media.
15．Why are audi and vide increasingly used by university teachers?
A．They can hld students' attentin.B．They are mre cnvenient t prepare.
C．They help develp advanced skills.D．They are mre infrmative than text.
16．What des the authr imply in the last paragraph?
A．Students shuld apply multiple learning techniques.
B．Teachers shuld prduce their wn teaching material.
C．Print texts cannt be entirely replaced in educatin.
D．Educatin utside the classrm cannt be ignred.
（2024·浙江·高考真题试卷）On September 7, 1991, the cstliest hailstrm (雹暴) in Canadian histry hit Calgary’s suthern suburbs. As a result, since 1996 a grup f insurance cmpanies have spent abut $2 millin per year n the Alberta Hail Suppressin Prject. Airplanes seed threatening strm cells with a chemical t make small ice crystals fall as rain befre they can grw int dangerus hailstnes. But farmers in east-central Alberta — dwnwind f the hail prject flights — wrry that precius misture (水分) is being stlen frm their thirsty land by the clud seeding.
Nrman Stienwand, wh farms in that area, has been addressing public meetings n this issue fr years. “Basically, the prvincial gvernment is letting the insurance cmpanies prtect the Calgary-Edmntn urban area frm hail,” Mr. Stienwand says, “but they’re increasing drught risk as far east as Saskatchewan.”
The Alberta hail prject is managed by Terry Krauss, a clud physicist wh wrks fr Weather Mdificatin Inc. f Farg, Nrth Dakta. “We affect nly a very small percentage f the ttal misture in the air, s we cannt be causing drught.” Dr. Krauss says. “In fact, we may be helping increase the misture dwnwind by creating wetter grund.”
One dubter abut the safety f clud seeding is Chuck Dswell, a research scientist wh just retired frm the University f Oklahma. “In 1999, I persnally saw significant trnades frm frm a seeded strm cell in Kansas,” Dr. Dswell says. “Des clud seeding create killer strms r reduce misture dwnwind? N ne really knws, f curse, but the seeding ges n.”
Given the degree f dubt, Mr. Stienwand suggests, “It wuld be wise t stp clud seeding.” In practice, dubt has had the ppsite effect. Due t the lack f scientific prf cncerning their impacts, n ne has succeeded in winning a lawsuit against clud-seeding cmpanies. Hence, private climate engineering can prceed in relative legal safety.
17．What des the prject aim t d?
A．Cnserve misture in the sil.B．Frecast disastrus hailstrms.
C．Prevent the frmatin f hailstnes.D．Investigate chemical use in farming.
18．Wh are ppsed t the prject?
A．Managers f insurance cmpanies.B．Farmers in east-central Alberta.
C．Prvincial gvernment fficials.D．Residents f Calgary and Edmntn.
19．Why des Dr. Dswell mentin the trnades he saw in 1999?
A．T cmpare different kinds f seeding methds.B．T illustrate the develpment f big hailstrms.
C．T shw the link between strms and misture.D．T indicate a pssible danger f clud seeding.
20．What can we infer frm the last paragraph?
A．Scientific studies have prved Stienwand right.B．Clud-seeding cmpanies will cntinue t exist.
C．The dubt abut clud seeding has disappeared.D．Private climate engineering is illegal in Canada.

【导语】本文是一篇议论文。文章主要讨论了哲学家对于宇宙的认知和信息时代下的作者对于宇宙争论的看法。
1．推理判断题。根据第一段“Searching the term “simulatin hypthesis” (模拟假说) returns numerus results that debate whether the universe is a cmputer simulatin —— a cncept that sme scientists actually take seriusly. Unfrtunately, this is nt a scientific questin. We will prbably never knw whether it’s true. We can, instead, use this idea t advance scientific knwledge.(搜索“模拟假说”这一术语会得到许多关于宇宙是否是计算机模拟的争论结果——一些科学家实际上认真对待这个概念。不幸的是，这不是一个科学问题。我们可能永远都不知道这是不是真的。相反，我们可以利用这个想法来推进科学知识)”可知，作者对于模拟假说提出质疑，是为了提出自己的建议，建议使用这一想法来推进科学知识。故选C项。
2．词句猜测题。根据第二段“If empirical (实证的) experience fails t reveal reality, reasning wn’t reveal reality either since it relies n cncepts and wrds that are cntingent n ur scial, cultural and psychlgical histries. Again, a black bx.(如果经验不能揭示现实，推理也不会揭示现实，因为它依赖于cntingent n我们的社会、文化和心理历史的概念和词语)”可知，句中that引导限制性定语从句，指代先行词cncepts and wrds，且结合常识，概念和词语取决于我们的社会、文化和心理历史，推测划线短语表示“取决于”，与determined by意义相近。故选B项。
3．推理判断题。根据第二段“The 18th-century philspher Kant argued that the universe ultimately cnsists f things-in-themselves that are unknwable. While he held the ntin that bjective reality exists, he said ur mind plays a necessary rle in structuring and shaping ur perceptins. (18世纪的哲学家康德认为，宇宙最终由不可知的事物本身组成。虽然他认为客观现实是存在的，但他说，我们的大脑在构建和塑造我们的感知方面发挥着必要的作用)”以及第三段“S, if we accept that the universe is unknwable, we als accept we will never knw if we live in a cmputer simulatin.(因此，如果我们接受宇宙是不可知的，我们也接受我们永远不会知道我们是否生活在计算机模拟中)”可知，作者引用康德的观点，并在客观陈述后利用该观点来构建自己的论述，由此可知，作者对康德的论点持欣赏的态度。故选A项。
4．推理判断题。根据第四段“There is n pint in arguing if the universe is a clck, a set f particles r an utput f cmputatin. All these mdels are tls t deal with the unknwn and t make discveries. And the mre tls we have, the mre effective and insightful we can becme. (争论宇宙是否是一个时钟、一组粒子还是计算输出的产物是没有意义的。所有这些模型都是处理未知事物和发现事物的工具。我们拥有的工具越多，我们就能变得越有效、越有洞察力)”以及第五段“It can be imagined that cmparable t the prcess f building previus scientific mdels, develping the “cmputer simulatin” metaphr-based mdel will als be a hugely rewarding exercise.(可以想象，与之前构建科学模型的过程相比，开发基于“计算机模拟”隐喻的模型也将是一项非常有益的工作)”可知，作者认为争论宇宙是否是虚拟的，这是没有意义的，我们应该停止争论宇宙是否为模拟，而应该着手于将其作为一个模型来探索和理解，这样会更有助于科学的进步。故选C项。
5．C 6．D 7．D 8．A
【导语】本文是说明文。文章主要讲述政府赞助了五辆名为圣卢卡斯的医疗列车为俄罗斯中部和东部偏远地区每年提供为期10个月的巡回医疗服务，为乡村居民提供基本医疗检查和治疗，改善当地医疗条件。

13．D 14．A 15．A 16．C
【导语】本文是议论文。主要讨论了纸质阅读与数字阅读、音频和视频学习方式的差异和效果。
13．词句猜测题。根据前文“When reading texts f several hundred wrds r mre, learning is generally mre successful when it’s n paper than nscreen. A large amunt f research cnfirms this finding.(当阅读几百字或更多的文本时，在纸上学习通常比在屏幕上学习更成功。大量的研究证实了这一发现)”可知，在纸上学习更有成效，以及后文“when experimenters mve frm psing simple tasks — like identifying the main idea in a reading passage — t nes that require mental abstractin — such as drawing inferences frm a text.(当实验人员从提出简单的任务(如识别阅读文章的主旨)转移到需要思维抽象的任务(如从文本中推断)时)”推知，此处应是表达“当实验者从简单的任务转向需要精神抽象的任务时，纸质阅读的益处就变得显而易见”之意，所以shine thrugh应是“显而易见”之意，和D项意思相近。故选D项。
14．推理判断题。根据第四段“But equally imprtant is the mental aspect. Reading researchers have prpsed a thery called “shallwing hypthesis (假说)”. Accrding t this thery, peple apprach digital texts with a mindset suited t scial media, which are ften nt s serius, and devte less mental effrt than when they are reading print.(但同样重要的是精神层面。阅读研究人员提出了一个名为“shallwing hypthesis”的理论。根据这一理论，人们以适合社交媒体的心态接触数字文本，这些文本通常不那么严肃，与阅读印刷品时相比，投入的精神努力也更少)”可知，shallwing hypthesis假设读者在阅读数字文本时会持有一种轻松的心态，不会像阅读纸质书籍那样投入太多的心理努力。故选A项。
15．细节理解题。根据第五段“Audi (音频) and vide can feel mre engaging than text, and s university teachers increasingly turn t these technlgies — say, assigning an nline talk instead f an article by the same persn.(音频和视频可能比文本更具吸引力，因此大学教师越来越多地转向这些技术，例如分配在线讲座而不是同一作者的文章)”可知，音频和视频比文本更能吸引学生的注意力，所以大学教师越来越多地使用这些技术。故选A项。
16．推理判断题。根据最后一段“Digital texts, audi and vide all have educatinal rles, especially when prviding resurces nt available in print. Hwever, fr maximizing learning where mental fcus and reflectin are called fr, educatrs shuldn’t assume all media are the same, even when they cntain identical wrds.(数字文本、音频和视频都具有教育作用，尤其是在提供印刷品中无法获得的资源时。然而，为了在需要精神集中和反思的情况下最大限度地学习，教育工作者不应假定所有媒体都是相同的，即使它们包含相同的单词)”可知，尽管数字文本、音频和视频在教育中有一定作用，但当需要精神集中和反思以最大化学习时，教育者不应假定所有媒体都是相同的，即使它们包含相同的单词。这表明作者认为纸质文本在教育中的作用仍然不可替代，因此暗示纸质文本在教育中的重要性。故选C项。
17．C 18．B 19．D 20．B
【导语】这是一篇说明文。文章主要介绍了1991年9月7日，加拿大历史上损失最大的冰雹袭击了卡尔加里的南郊。因此，自1996年以来，一组保险公司每年在艾伯塔省冰雹抑制项目上花费约200万美元。飞机在有威胁的风暴中心中播撒一种化学物质，使小冰晶在变成危险的冰雹之前像雨一样落下。但是，在艾伯塔省中东部的农民们担心，“冰雹计划”飞行的下风处，宝贵的水分正被人工降雨从他们干渴的土地上偷走。
17．细节理解题。根据第一段中“As a result, since 1996 a grup f insurance cmpanies have spent abut $2 millin per year n the Alberta Hail Suppressin Prject. Airplanes seed threatening strm cells with a chemical t make small ice crystals fall as rain befre they can grw int dangerus hailstnes.(因此，自1996年以来，一组保险公司每年在艾伯塔省冰雹抑制项目上花费约200万美元。飞机在有威胁的风暴中心中播撒一种化学物质，使小冰晶在变成危险的冰雹之前像雨一样落下)”可知，这个项目的目标是防止冰雹的形成。故选C。
18．细节理解题。根据第一段中“But farmers in east-central Alberta — dwnwind f the hail prject flights — wrry that precius misture (水分) is being stlen frm their thirsty land by the clud seeding.(但是，在艾伯塔省中东部的农民们担心，“冰雹计划”飞行的下风处，宝贵的水分正被人工降雨从他们干渴的土地上偷走)”可知，艾伯塔省中东部的农民反对这个项目。故选B。
19．推理判断题。根据倒数第二段“One dubter abut the safety f clud seeding is Chuck Dswell, a research scientist wh just retired frm the University f Oklahma. “In 1999, I persnally saw significant trnades frm frm a seeded strm cell in Kansas,” Dr. Dswell says. “Des clud seeding create killer strms r reduce misture dwnwind? N ne really knws, f curse, but the seeding ges n.”(查克·多斯韦尔是一位刚刚从俄克拉何马大学退休的研究科学家，他对人工降雨的安全性持怀疑态度。“1999年，我在堪萨斯州亲眼目睹了由种子风暴细胞形成的重大龙卷风，”多斯韦尔博士说。“人工降雨会制造致命风暴还是减少顺风处的水分？当然，没有人真正知道，但是播种还在继续。”)”可推知，多斯韦尔博士提到他在1999年看到的龙卷风是为了提示人工降雨可能带来的危险。故选D。
20．推理判断题。根据最后一段“Given the degree f dubt, Mr. Stienwand suggests, “It wuld be wise t stp clud seeding.” In practice, dubt has had the ppsite effect. Due t the lack f scientific prf cncerning their impacts, n ne has succeeded in winning a lawsuit against clud-seeding cmpanies. Hence, private climate engineering can prceed in relative legal safety.(考虑到质疑的程度，斯廷旺德建议，“停止人工降雨是明智的。”在实践中，怀疑产生了相反的效果。由于缺乏有关其影响的科学证据，没有人成功地赢得了对人工降雨公司的诉讼。因此，私人气候工程可以在相对合法的安全条件下进行)”可推知，从最后一段我们能推断出人工降雨公司将继续存在。故选B。
