2027届新高考高三第一轮复习 高三英语备课组 新课标 · 新高考2027届高三第一轮复习 课后同步作业练习 答案与解析 第9讲　UNIT 1　Nature in the balance 班级：_________ 学号：_________ 姓名：_________ 分数：_________ Ⅰ.阅读理解(每小题2.5分,共30分) (2026·石家庄市高三质量检测) A third of the Arctic’s tundra(北极冻原),forests and wetlands have become a source of carbon emissions(排放),a new study has found,as global heating ends thousands of years of carbon storage. For thousands of years,Arctic land ecosystems have acted as a deep-freeze,holding potential emissions in the tundra.But ecosystems in the region are releasing more CO2 into the atmosphere with rising temperatures,a study published in Nature Climate Change concluded. More than 30% of the region is a source of CO2,according to the analysis,rising to 40% when emissions from wildfires are included.By using data from 200 study sites between 1990 and 2020,the research demonstrates how the Arctic’s tundra,forests and wetlands are being transformed by rapid warming. The shift is occurring despite the Arctic becoming greener.“In one place where I work in Alaska,when the tundra unfreezes,the plants that absorb CO2 grow more,so you can sometimes get an uptick in carbon storage,”Sue Natalia,the lead researcher said.“But the tundra continues to unfreeze and the microbes(微生物) take over.You can visually see the changes in the landscape.” There is a growing concern about the natural processes that regulate the Earth’s climate,which are being affected by rising temperatures.Together,the planet’s oceans,forests,soils and other natural carbon sinks absorb about half of all human emissions,but there are signs that these sinks are under stress. The Arctic ecosystem has been gathering carbon for thousands of years,helping cool the atmosphere.In a warming world,the researchers say,its carbon cycle is beginning to change and needs better monitoring.Dr Anna Virkkala,the author of the study,said,“The carbon in the Arctic soil is close to half of the Earth’s soil carbon pool,much more than in the atmosphere.This huge pool should ideally stay in the ground.But now,rising temperatures are speeding the breakdown of plant and animal remains,which releases stored carbon back into the air as greenhouse gases like CO2,creating a cycle that fuels even more warming.” 【语篇解读】　本文是一篇说明文。一项研究表明,因全球变暖,三分之一的北极冻原、森林和湿地变为碳排放源。多年以来北极生态系统扮演着储存碳的“深冷冻柜”角色,现因升温释放更多二氧化碳。人们需要更好地监测北极的碳循环变化。 1.What’s the main reason for the release of carbon from Arctic soils? A.Tundra defrosting. B.Wildfire erupting. C.Tree over-cutting. D.Wetland disappearing. 答案　A　[推理判断题。根据第二段中的“For thousands of years...releasing more CO2 into the atmosphere with rising temperatures”以及第四段中的“But the tundra continues to unfreeze and the microbes(微生物) take over.”可知,北极的陆地生态系统在过去几千年中一直是碳储存的“深冷冻柜”,但随着全球变暖,这些生态系统正在释放更多的二氧化碳;冻原仍在持续解冻,微生物开始占据主导地位。故可推知冻原解冻是北极土壤中碳释放的主要原因。故选A。] 2.What does the underlined word“uptick”in paragraph 4 mean? A.Boost. B.Loss. C.Limit. D.Release. 答案　A　[词义猜测题。根据第四段中的“when the tundra unfreezes,the plants that absorb CO2 grow more,so you can sometimes get an uptick in carbon storage”并结合常识可知,当冻原解冻时,吸收二氧化碳的植物生长得更多,所以在这种情况下碳储存量应该是有所增加。故选A。boost “增长,提高”。] 3.What can we infer about the Arctic’s soil carbon pool according to Dr Anna Virkkala? A.It has less carbon than the air. B.It ought to be stored in the tundra. C.It can break down organic matter. D.It is less affected by global warming. 答案　B　[推理判断题。根据第六段中Anna Virkkala博士说的话“The carbon in the Arctic...ideally stay in the ground.”可知,Anna Virkkala认为北极土壤中的碳库巨大,理想情况下应该留在地下,也就是应该被储存在冻原中。故选B。] 4.What is the main idea of the text? A.Arctic greening cuts carbon emissions. B.More carbon is being released in Arctic. C.Arctic carbon storage is growing rapidly. D.Extreme climate makes Arctic inhabitable. 答案　B　[主旨大意题。文章开篇就指出三分之一的北极冻原、森林和湿地已成为碳排放源,接着阐述了随着全球变暖,北极生态系统的变化导致更多碳被释放,虽然北极绿化状况有改善,但整体上北极还是在释放更多碳,所以文章主要是在说北极正在释放更多的碳。故选B。A项“北极绿化减少了碳排放”;B项“北极正在释放更多的碳”;C项“北极的碳储存正在迅速增长”;D项“极端气候使北极不适宜居住”。] (2026·长沙市新高考适应性考试) Artificial intelligence—or AI—is the computer code(代码) that allows a machine to do something that normally requires a human brain.On TikTok,for instance,AI sorts the posts so that the first ones you see are likely to be those you’d prefer.But before AI can do any of that,developers must train it.And the training consumes energy. AI training is powered mostly by fossil(化石) fuels,according to one of the largest studies of its kind.Less than 25 percent of AI uses low-carbon energy sources such as hydroelectricity and nuclear power during training.In fact,researchers now worry that training’s appetite for energy could soon become a huge problem.The energy to develop AI comes out of the electrical net.And in most parts of the world,making electricity emits(排放) carbon dioxide and other greenhouse gases into the air. Language-processing AI systems learn by devouring(吞食) texts in a particular language.This might include “reading” everything ever published online in some language,including libraries full of old books that have been digitalized.Such data-intensive training uses a lot of energy.To translate between English and Chinese,for example,an AI model may deal with millions or even billions of translated books and articles.In this way,it learns which words and phrases match.Later,when given a new text,it recommends its own translation. In 2019,researchers calculated the impact of developing the AI model named Transformer.It released a massive 626,000 pounds of carbon dioxide.That’s equal to the greenhouse gases that would be poured by five American cars from when they were made to when they were junked. Today,most AI development happens at data centers.These computer-filled buildings account for some 2 percent of US electricity use and 1 percent of global energy use.Some AI experts have sounded an alarm about the threat these energy giants pose. 【语篇解读】　本文是一篇说明文。开发人工智能给人们的生活带来了很多便利,但是开发人工智能需要消耗大量能源,会向空气中排放二氧化碳和其他温室气体。 5.What is AI training mainly energized by? A.Fossil fuels. B.Solar energy. C.Nuclear energy. D.Greenhouse gases. 答案　A　[细节理解题。根据第二段中的“AI training is powered mostly by fossil(化石) fuels”可知,人工智能训练主要由化石燃料提供动力。故选A。原文的fossil fuels与A项为原词复现。A项“化石燃料”;B项“太阳能”;C项“核能”;D项“温室气体”。] 6.What do we know about the language-processing AI systems? A.They process limited texts. B.They will replace translators. C.They seldom read digital books. D.They are energy-consuming. 答案　D　[细节理解题。根据第三段中的“Language-processing AI systems learn...a lot of energy.”可知,语言处理人工智能系统通过吞食特定语言的文本来学习。这可能包括“阅读”网上用某种语言出版的所有东西,包括涵盖了已数字化旧书的系列丛书。这种数据密集型训练需要消耗大量能源。故选D。文中的“uses a lot of energy”与D项中的energy-consuming是同义转换。] 7.Why does the author mention Transformer in paragraph 4? A.To highlight its significance. B.To speak highly of AI’s power. C.To demonstrate researchers’ creativity. D.To stress its effect on the environment. 答案　D　[写作目的题。根据第四段可知,2019年,研究人员推测了开发名为Transformer的人工智能模型的影响。它释放了626 000磅的二氧化碳,这相当于五辆美国汽车从制造到报废所排放的温室气体。提到Transformer是为了强调它对环境的影响。] 8.What does the author imply in the last paragraph? A.AI’s development poses a threat to data centers. B.The energy consumption of AI can’t be ignored. C.AI is effectively transforming the way we learn. D.People should take action to reduce gas emissions. 答案　B　[推理判断题。根据最后一段可知,大多数人工智能开发都在数据中心进行。这些充满电脑的建筑占美国用电量的2%,占全球用电量的1%。一些人工智能专家对这些能源巨头构成的威胁发出了警告。从中我们可以推断出,人工智能的能耗是不容忽视的。] (2026·杭州市高三年级第二学期教学质量检测) Plastic and cheap clothes are not a glorious legacy (遗产). But a scientist exploring which items from our technological civilisation are most likely to survive for many millions of years as fossils (化石) has reached an ironic and instructive conclusion: Plastic and fast fashion will be our everlasting geological signature. “Plastic will definitely be a signature ‘technofossil’,because it is incredibly durable. We are making massive amounts of it,and it gets around the entire globe,” says Sarah Gabbott,a University of Leicester expert on fossils.“So wherever those future civilisations dig,they are going to find plastic.” Clothes will also make an abrupt entry into humanity’s fossil record. Today,the world’s growing population often wears mass-produced synthetic (合成的) clothing that is rapidly dumped and it is not as easily rotted as cotton and silk. “We are making it in ridiculous amounts,” says Gabbott.“We stick it into landfills(废物填埋场),which are like giant mummification tombs. It is already clear that much of modern fashion will end up being truly timeless.” Fossils are not just objects left behind,but also the traces of life’s activity written into the rocks. Human activities,such as oil drilling and nuclear tests,will leave lasting scars. Humankind has also created many near-indestructible chemicals,such as dioxins and DDT. Given that similar molecules produced by bacteria have been found in rocks that are 1,600 million years old in Western Australia,these chemicals appear to be here to stay.“And there is the graphite (石墨) used in pencils,” says Gabbott.“It is endearing to think that it may be the drawings of children that may survive best of all: a pencil portrait,perhaps,of a family outside a house,with the sun shining and a rainbow arcing across the sky,” she says jokingly. “The big message here is that the amount of stuff we are now making is eye-watering — it’s off the scale,” says Gabbott. All of the stuff made by humans by 1950 was a small part of all the matter on Earth. But today it outweighs all plants and animals. “This raises serious questions for us all,” she says. “Do you need that? Do you really need to buy more?” 【语篇解读】　本文是一篇说明文。文章主要说明了塑料和快时尚等人类大量制造且耐用的物品将成为人类在地质历史上永恒的标志,这引发了人们对消费行为的思考。 9.What does the author think of the legacy mentioned in paragraph 1? A.Troubling. B.Short-lived. C.Technologically weak. D.Environmentally harmless. 答案　A　[观点态度题。根据第一段中的“Plastic and cheap clothes are not a glorious legacy (遗产).”可知,作者认为塑料和廉价衣服并非光彩的遗产;再结合后文讲述的塑料和被快速丢弃的合成衣物对环境的影响可推断出,作者觉得这些遗产是令人担忧的,故选A。] 10.What can be categorized as technofossils? A.Dinosaur bones. B.Cotton clothing. C.Nuclear waste. D.Solid landfills. 答案　C　[细节理解题。根据第二段中的“Plastic will definitely be a signature ‘technofossil’,because it is incredibly durable.”以及第五段中的“Human activities,such as oil drilling and nuclear tests,will leave lasting scars.”可知,技术化石是人类技术产生的且能长久留存的物质,核废料是人类核活动产生且难以消失的,可归类为技术化石,故选C。A项“恐龙骨头”;B项“棉质衣物”;C项“核废料”;D项“固体垃圾填埋场”。] 11.Why is “the drawings of children” mentioned in paragraph 5? A.To highlight human creativity. B.To celebrate modern technology. C.To stress that warmth of life is here to stay. D.To indicate that chemicals could be fossilized. 答案　D　[写作目的题。根据第五段的内容可知,该段提到人类制造了许多几乎不可摧毁的化学物质,即这些化学物质能长久留存,接着以儿童绘画为例说了铅笔中的石墨的长久留存,所以提到儿童绘画是为了表明像石墨这样的化学物质可以被石化,被留存很久,故选D。A项“为了突出人类创造力”;B项“为了赞美现代技术”;C项“为了强调生活的温暖会留存”;D项“为了表明化学物质可以被石化”。] 12.What is Gabbott’s primary concern? A.Biodiversity loss. B.Geological record accuracy. C.Technological progress. D.Overproduction of material goods. 答案　D　[推理判断题。根据最后一段中 Gabbott 说的话“The big message here is that the amount of stuff we are now making is eye-watering—it’s off the scale”以及“Do you need that? Do you really need to buy more?”可知,Gabbott强调人类现在制造的物质数量令人痛苦,已经离谱了,并对人们的消费需求提出质疑。所以她主要关心的是物质产品的过度生产,故选D。A项“生物多样性丧失”;B项“地质记录准确性”;C项“技术进步”;D 项“物质产品的过度生产”。] Ⅱ.七选五(每小题2.5分,共12.5分) (2026·青岛市高三年级第一次适应性检测) We are so passionate about what we do.We get to travel this amazing world,make great friendships,make positive changes within local communities and help conserve animals. 　1　.  It is not a nine-to-five job for us.
