专题16 科普类说明文2018高考题D【2018全国I】We may think were a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices(装置) well after they go out of style. Thats bad news for the environment and our wallets as these outdated devices consume much more energy than the newer ones that do the same things.To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s. Devices were grouped by generation Desktop puters, basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.As we accumulated more devices, however, we didnt throw out our old ones. The living-room television is replaced and gets planted in the kids room, and suddenly one day, you have a TV in every room of the house, said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. Were not just keeping these old devices we continue to use them. According to the analysis of Babbitts team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions（排放）more than doubling during the 1992 to 2007 window.So whats the solution（解决方案）? The teams data only went up to 2007, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop puters could cut energy consumption by 44%.32. What does the author think of new devices?A. They are environment-friendly. B. They are no better than the old.C. They cost more to use at home. D. They go out of style quickly.33. Why did Babbitts team conduct the research?A. To reduce the cost of minerals.B. To test the life cycle of a product.C. To update consumers on new technology.D. To find out electricity consumption of the devices.34. Which of the following uses the least energy?A. The box-set TV. B. The tablet.C. The LCD TV. D. The desktop puter.35. What does the text suggest people do about old electronic devices?A. Stop using them. B. Take them apart.C. Upgrade them. D. Recycle them.【答案】32. A 33. D 34. B 35. A【解析】本文是一篇科普说明文。文章讲述了新旧电子设备的差别，旧电子设备耗能高，不环保。所以作者主张使用新电子设备。33. 细节理解题。根据文章第二段中的To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life 可知，Babbitts team研究的目的是弄清楚这些设备用了多少电。故选D。34. 细节理解题。根据文章最后一段中的They found that more on-demand entertainment viewing on tablets instead of TVs and desktop puters could cut energy consumption by 44%.可知，平板电脑是耗能最少的电子设备，可以降低44%的耗能。故选B。35. 推理判断题。根据文章的整体内容可知，因为旧的电子设备耗能高，不环保。所以作者建议停止使用旧的电子设备。故选A。点睛：熟悉比较句型是彻底理解本文的关键，也是解题的关键。本文中的比较句型：1. Thats bad news for the environment and our wallets as these outdated devices consume much more energy than the news ones that do the same things做同样的事，旧的过时的装置比新装置消耗更多能源，对环境有害，浪费钱财。2. According to the analysis of Babbitts team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions (排放) more than doubling during the 1992 to 2007 window.根据Babbitt团队的分析，旧的桌面监视器和阴极射线管箱式电视机是最差的电子设备，它们的耗能和温室气体的排放是1992到2007window的两倍还多。3. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop puters could cut energy consumption by 44%.他们发现在平板电脑上看的随需变化的娱乐节目比在电视和电脑上看耗能减少了44%。 B【2018浙江】 Steven Stein likes to follow garbage trucks. His strange habit makes sense when you consider that hes an environmental scientist who studies how to reduce litter, including things that fall off garbage trucks as they drive down the road. What is even more interesting is that one ofSteins jobs is defending an industry behind the plastic shopping bags. Americans use more than 100 billion thin film plastic bags every year. So many end up in tree branches or along highways that a growing number of cities do not allow them at checkouts(收银台) . The bags are prohibited in some 90 cities in California, including Los Angeles. Eyeing these headwinds, plastic-bag makers are hiring scientists likeSteintomake the case that their products are not as bad for the planet as most people assume. Among the bag makers argument: many cities with bans still allow shopperstopurchase paper bags, which are easily recycled but require more energytoproduce and transport. And while plastic bags may be uglytolook at, they represent a small percentage of allgarbageon the ground today The industry has also taken aim at the product that has appeared as its replacement: reusable shopping bags. The stronger a reusable bag is, the longer its life and the more plastic-bag use it cancels out. However, longer-lasting reusable bags often require more energytomake. One study found that a cotton bag must be used at least 131 times to be better for the planet than plastic. Environmentalists dont dispute（质疑） these points. They hope paper bags will be banned someday too and want shopperstouse the same reusable bags for years.24. What has Steven Stein been hired to do?A. Help increase grocery sales.B. Recycle the waste material.C. Stop things falling off trucks.D. Argue for the use of plastic bags.25. What does the word “headwinds”in paragraph 2 refer to?A. Bans on plastic bags.B. Effects of city development.C. Headaches caused by garbage.D. Plastic bags hung in trees.26. What is a disadvantage of reusable bags according to plastic-bag makers?A. They are quite expensive.B. Replacing them can be difficult.C. They are less strong than plastic bags.D. Producing them requires more energy.27. What is the best title for the text?A. Plastic, Paper or NeitherB. Industry, Pollution and EnvironmentC. Recycle or Throw AwayD. Garbage Collection and Waste Control【答案】24. D 25. A 26. D 27. A【解析】文章分析了几种购物袋的使用情况，塑料袋造成了环境问题，尽管纸袋容易回收，但生产和运输需要更多的能源，希望消费者使用耐用可重复使用的袋子。24. 细节理解题。根据第一段one ofSteins jobs is defending an industry behind the plastic shopping bags.和第二段plastic-bag makers are hiring scientists likeSteintomake the case that their products are not as bad for the planet as most people assume.可知塑料袋生产商雇用Steven Stein是为了证明他们的产品并不像大多数人想象的那样对地球有害，是对塑料袋被禁用的解释和争论。故选D。25. 词义猜测题。上文介绍在许多美国大城市塑料袋被禁用，看到这种现状，塑料袋生产商雇用Steven Stein等科学家是为了证明他们的产品并不像大多数人想象的那样对地球有害。headwinds“逆风”，此处指塑料袋被禁用的现状，即Bans on plastic bags，故选A。26. 细节理解题。根据第四段However, longer-lasting reusable bags often require more energytomake.可知塑料袋生产商认为生产耐用且能重复使用的袋子需要更多的能量，故选D。27. 标题归纳题。文章讲述了使用塑料袋造成的环境问题，纸袋容易回收，但生产和运输需要更多的能源，希望消费者使用耐用可重复使用的袋子。对这三种方式进行了对比，Plastic, Paper or Neither既能概括全文，又能吸引读者，最适合作为标题。故选A。【点睛】概括主旨的方法是：先看首尾或各段开头再看全文找主题句，若无明显主题句，就通过关键词句来概括(如议论文中寻找表达作者观点态度的词句，要看懂全文的主要内容，明白了主要内容就能准确概括文章标题。小题4要求概括标题，本文讲述了使用塑料袋造成的环境问题，纸袋容易回收，但生产和运输需要更多的能源，希望消费者使用耐用可重复使用的袋子。对这三种方式进行了对比，Plastic, Paper or Neither既能概括全文，又能吸引读者，适合作为标题。C【2018天津卷】Theres a new frontier in 3D printing thats beginning to e into focus: food. Recent development has made possible machines that print, cook, and serve foods on a mass scale. And the industry isnt stopping there.Food productionWith a 3D printer, a cook can print plicated chocolate sculptures and beautiful pieces for decoration on a wedding cake. Not everybody can do that it takes years of experience, but a printer makes it easy. A restaurant in Spain uses a Foodini to “re-create forms and pieces” of food that are “exactly the same,” freeing cooks to plete other tasks. In another restaurant, all of the dishes and desserts it serves are 3D-printed,rather than farm to table.Sustainability(可持续性）The global population is expected to grow to 9.6 billion by 2050, and some analysts estimate that food production will need to be raised by 50 percent to maintain current levels. Sustainability is being a necessity. 3D food printing could probably contribute to the solution. Some experts believe printers could use hydrocolloids (水解胶体) from plentiful renewables like algae(藻类) and grass to replace the familiar ingredients(烹饪原料). 3D printing can reduce fuel use and emissions. Grocery stores of the future might stock food that lasts years on end, freeing up shelf space and reducing transportation and storage requirements.NutritionFuture 3D food printers could make processed food healthier. Hod Lipson, a professor at Columbia University, said, “Food printing could allow consumers to print food with customized nutritional content, like vitamins. So instead of eating a piece of yesterdays bread from the supermarket, youd eat something baked just for you on demand.”ChallengesDespite recent advancements in 3D food printing, the industry has many challenges to overe. Currently, most ingredients must be changed to a paste(糊状物) before a printer can use them, and the printing process is quite time-consuming, because ingredients interact with each other in very plex ways. On top of that, most of the 3D food printers now are restricted to dry ingredients, because meat and milk products may easily go bad. Some experts are skeptical about 3D food printers, believing they are better suited for fast food restaurants than homes and high-end restaurants.46. What benefit does 3D printing bring to food production?A. It helps cooks to create new dishes.B. It saves time and effort in cooking.C. It improves the cooking conditions.D. It contributes to restaurant decorations.47. What can we learn about 3D food printing from Paragraphs 3?A. It solves food shortages easily.B. It quickens the transportation of food.C. It needs no space for the storage of food.D. It uses renewable materials as sources of food.48. According to Paragraph 4, 3D-printed food _.A. is more available to consumersB. can meet individual nutritional needsC. is more tasty than food in supermarketsD. can keep all the nutrition in raw materials49. What is the main factor that prevents 3D food printing from spreading widely?A. The printing process is plicated.B. 3D food printers are too expensive.C. Food materials have to be dry.D. Some experts doubt 3D food printing.50. What could be the best title of the passage?A. 3D Food Printing: Delicious New TechnologyB. A New Way to Improve 3D Food PrintingC. The Challenges for 3D Food ProductionD. 3D Food Printing: From Farm to Table【答案】46. B 47. D 48. B 49. C 50. A【解析】本文是一篇科普类短文阅读。文章主要介绍了3D打印技术在食物上的应用取得了进展，但目前仍面临着许多方面的挑战。46. 推理判断题。根据文章Food production中叙述了没有经验的人可以用3D打印机做出复杂的巧克力雕塑和美丽的婚礼蛋糕，以及餐厅能够用3D打印出所有的菜肴和甜点，从而可以推断出3D打印的优势是节省了做饭的时间和精力。故选B。48. 推理判断题。根据文章第四段Food printing could allow consumers to print food with customized nutritional content, like vitamins.（食品打印可以让消费者打印定制营养的食物），从而可以推断出3D打印出来的食物可以满足个人营养需求。故选B。49. 细节理解题。根据文章最后一段most of the 3D food printers now are restricted to dry ingredients, because meat and milk products may easily go bad.可知，阻止3D打印食物进一步广泛使用的原因是原料必须是干的，含水多的肉和牛奶不能应用于3D打印因为很容易坏。故选C。50. 主旨大意题。文章主要介绍了3D打印技术在食物上的应用取得了进展，但目前仍面临着许多方面的挑战。所以用标题3D Food Printing: Delicious New Technology，故选A。 点睛：科普类说明文历来是高考阅读理解命题的重点。本文是一篇3D打印技术在食物方面的应用，文章运用一些小标题和对一些专业词汇作了多处中文注释，降低了考生的阅读难度。文章逻辑性强，条理清楚，主要考查学生对语篇的整体把握和领悟能力以及对特定细节的认读和处理能力。最后一小题考查主旨大意，为文章选择出最好的标题。考生做此题时一定要注意选择项必须要能概括整个文章的内容，不能以偏概全。如B、C、D选择项在文章中都有所涉及，但不足以概括全文，所以需要考生正确概括全文的主旨大意。C2018北京卷Plastic-Eating WormsHumans produce more than 300 million tons of plastic every year. Almost half of that winds up in landfills(垃圾填埋场), and up to 12 million tons pollute the oceans. So far there is no effective way to get rid of it, but a new study suggests an answer may lie in the stomachs of some hungry worms. Researchers in Spain and England recently found that the worms of the greater wax moth can break down polyethylene, which accounts for 40% of plastics. The team left 100 wax worms on a mercial polyethylene shopping bag for 12 hours, and the worms consumed and broke down about 92 milligrams, or almost 3% of it. To confirm that the worms chewing alone was not responsible for the polyethylene breakdown, the researchers made some worms into paste(糊状物) and applied it to plastic films. 14 hours later the films had lost 13% of their mass apparently broken down by enzymes (酶) from the worms stomachs. Their findings were published in Current Biology in 2017.Federica Bertocchini, co-author of the study, says the worms ability to break down their everyday food beeswax also allows them to break down plastic. Wax is a plex mixture, but the basic bond in polyethylene, the carbon-carbon bond, is there as well, she explains, The wax worm evolved a method or system to break this bond. Jennifer DeBruyn, a microbiologist at the University of Tennessee, who was not involved in the study, says it is not surprising that such worms can break down polyethylene. But pared with previous studies, she finds the speed of breaking down in this one exciting. The next step, DeBruyn says, will be to identify the cause of the breakdown. Is it an enzyme produced by the worm itself or by its gut microbes(肠道微生物)?Bertocchini agrees and hopes her teams findings might one day help employ the enzyme to break down plastics in landfills. But she expects using the chemical in some kind of industrial process not simply millions of worms thrown on top of the plastic.43. What can we learn about the worms in the study?A. They take plastics as their everyday food.B. They are newly evolved creatures.C. They can consume plastics.D. They wind up in landfills.44. According to Jennifer DeBruyn, the next step of the study is to .A. identify other means of the breakdownB. find out the source of the enzymeC. confirm the research findingsD. increase the breakdown speed45. It can be inferred from the last paragraph that the chemical might .A. help to raise wormsB. help make plastic bagsC. be used to clean the oceansD. be produced in factories in future46. What is the main purpose of the passage?A. To explain a study method on worms.B. To introduce the diet of a special worm.C. To present a way to break down plastics.D. To propose new means to keep eco-balance.C【文章大意】 本文是一篇科普知识类文章。从环保理念出发，文章围绕一种可以降解塑料的虫子大蜡螟展开，描述了研究进展及虫子能降解塑料的原理，即使用其胃中的酶降解塑料，为塑料污染问题提供了新的思路。43. C细节理解题。根据文章第二段中的“The team left 100 wax worms on a mercial polyethylene shopping bag for 12 hours, and the worms consumed and broke down about 92 milligrams, or almost 3% of it.”可知，这些虫子可以消耗聚乙烯购物袋，即塑料袋。故选C。44. B推理判断题。根据文章第二段中的“The next step, DeBruyn says, will be to identify the cause of the breakdown. Is it an enzyme produced by the worm itself or by its gut microbes (肠道微生物)？”可知，下一步是探究酶的来源。故选C。45. D推理判断题。根据文章最后一段“But she expects using the chemical in some kind of industrial process-not simply millions of worms thrown on top of the plastic”可知研究者希望那些化学物品可以批量生产，而不是将许多虫子直接扔在垃圾堆里。故选D。46. C写作意图题。全文都在围绕可以降解垃圾的虫子展开，文章的目的就是向读者呈现这种独特的降解塑料的方式。故选A。2017高考题科普知识类 2017北京卷DHollywoods theory that machines with evil(邪恶的) minds will drive armies of killer robots is just silly. The real problem relates to the possibility that artificial intelligence(AI) may bee extremely good at achieving something other than what we really want. In 1960 a wellknown mathematician Norbert Wiener, who founded the field of cybernetics(控制论), put it this way: “If we use, to achieve our purposes, a mechanical agency with whose operation we cannot effectively interfere(干预), we had better be quite sure that the purpose put into the machine is the purpose which we really desire.”A machine with a specific purpose has another quality, one that we usually associate with living things: a wish to preserve its own existence. For the machine, this quality is not inborn, nor is it something introduced by humans; it is a logical consequence of the simple fact that the machine cannot achieve its original purpose if it is dead. So if we send out a robot with the single instruction of fetching coffee, it will have a strong desire to secure success by disabling its own off switch or even killing anyone who might interfere with its task. If we are not careful, then, we could face a kind of global chess match against very determined, super intelligent machines whose objectives conflict with our own, with the real world as the chessboard. The possibility of entering into and losing such a match should concentrate the minds of puter scientists. Some researchers argue that we can seal the machines inside a kind of firewall, using them to answer difficult questions but never allowing them to affect the real world. Unfortunately, that plan seems unlikely to work: we have yet to invent a firewall that is secure against ordinary humans, let alone super intelligent machines.Solving the safety problem well enough to move forward in AI seems to be possible but not easy. There are probably decades in which to plan for the arrival of super intelligent machines. But the problem should not be dismissed out of hand, as it has been by some AI researchers. Some argue that humans and machines can coexist as long as they work in teamsyet that is not possible unless machines share the goals of humans. Others say we can just “switch them off” as if super intelligent machines are too stupid to think of that possibility. Still others think that super intelligent AI will never happen. On September 11, 1933, famous physicist Ernest Rutherford stated, with confidence, “Anyone who expects a source of power in the transformation of these atoms is talking moonshine.” However, on September 12, 1933, physicist Leo Szilard invented the neutroninduced(中子诱导) nuclear chain reaction.67Paragraph 1 mainly tells us that artificial intelligence may _Arun out of human controlBsatisfy humans real desiresCmand armies of killer robotsDwork faster than a mathematician68Machines with specific purposes are associated with living things partly because they might be able to _Aprevent themselves from being destroyedBachieve their original goals independentlyCdo anything successfully with given ordersDbeat humans in international chess matches69According to some researchers, we can use firewalls to _Ahelp super intelligent machines work betterBbe secure against evil human beingsCkeep machines from being harmedDavoid robots affecting the world70What does the author think of the safety problem of super intelligent machines?AIt will disappear with the development of AI.BIt will get worse with human interference.CIt will be solved but with difficulty.DIt will stay for a decade.【文章大意】 本文为科普类文章，讲的是随着科技的发展，人工智能 (AI)可能会超出人类的控制。67A段落大意题。第一段第二句说“人工智能虽然擅长完成任务，但这有可能不是我们真正想要的”。因此选A。【名师点睛】推理判断题属于主观题，是层次较高的题目。它包括判断题和推理题。这两类题常常相互依存，推理是为了作出正确的判断，正确的判断又依赖于合乎逻辑的推理。此类题要求在理解表面文字的基础上，作出判断和推论，从而得到文章的隐含意思和深层意思，也就是通过文章中的文字信息、上下文的逻辑关系及事物的发展变化等已知的信息，推断出作者没有直接表达的态度和观点。推理判断题的解题方法 ：推理判断题不仅要求考生读懂文章中的每个句子的意思还要推理它们之间的关系，结合自己的生活常识和经验，再通过逻辑推理和判断，理解文章的言外之意，从而揭示文章的深层涵义。任何一篇文章都有其特定的写作目的，读者需要知道如何去做或按照某种方式思考问题。推理判断题的答案不可能在文章中直接找到，因此推理时我们务必要忠于原文，在文章中寻找并确定可推论的依据，即：已知部分推论的前提，从中推测出未知部分推理的结论，切忌妄加评论，把自己的观点当成作者的观点。 2017江苏卷BBefore birth，babies can tell the difference between loud sounds and voices.
