The Antarctic summer sea ice has started to decline since 2016， reported the BBC. In February 2023， the total area of sea ice reached a record low of 1.91 million square kilometers. 英 语·必修第一册（WY） 目 录 　　“Penguins depend on sea ice， a stable platform for them， to bring up their young，” Peter Fretwell from UK’s national polar research institute told the BBC. If the ice platform melts or breaks apart before chicks develop their waterproof feathers， they are more likely to drown or freeze to death.For this reason， emperor penguins are now choosing to raise their babies on the ice shelf， which is firmly attached （附着） to the land.Therefore， chicks must face the challenge of jumping off a high cliff. 英 语·必修第一册（WY） 目 录 　　According to Live Science， the decrease in the ice has caused thousands of emperor penguin chicks to die in West Antarctica in 2022.The continuing drop of sea ice may force more penguins to make their nests on ice shelves.“It’s heartbreaking to think that the whole species may be gone if climate change continues on the path that it’s on at the moment，” said Fretwell. 语篇解读：本文是一篇新闻报道。文章主要报道了南极帝企鹅幼崽 因海冰快速融化被迫从高崖跳下，海冰减少致大量幼崽死亡，气候 变化正严重威胁帝企鹅的生存。 语篇解读：本文是一篇新闻报道。文章主要报道了南极帝企鹅幼崽 因海冰快速融化被迫从高崖跳下，海冰减少致大量幼崽死亡，气候 变化正严重威胁帝企鹅的生存。 英 语·必修第一册（WY） 目 录 1. Which is NOT mentioned about penguin chicks in paragraph 2？ （　　） A. Eating habits. B. Living conditions. C. Changing feathers. D.

They want to challenge themselves. C. The ice shelves provide more food. D. The ice platforms are melting rapidly. 解析：　细节理解题。根据第三、四段可知，海冰平台快速融化是 幼崽被迫跳高崖的原因。 √ 英 语·必修第一册（WY） 目 录 3.

Increase. 解析：　词义猜测题。根据画线词下文In February 2023， the total area of sea ice reached a record low of 1.91 million square kilometers.可 知，自从2016年以来，南极夏季，海冰开始减少。画线词decline表示 “减少”，与decrease意义相近。 √ 英 语·必修第一册（WY） 目 录 4.

Secrets of the Penguins： A Documentary about Antarctic 解析：　标题归纳题。根据文章内容可知，本文介绍了海冰融化、 帝企鹅幼崽生存危机，文章核心是气候变化对帝企鹅生存的威胁，所 以C项（气候变化：帝企鹅生存的威胁）适合作为文章标题。 √ 英 语·必修第一册（WY） 目 录 B 　　（2026·陕西延安期末）It is universally believed that the destruction and disappearance of coral reefs （珊瑚礁）， essential parts of the ocean ecosystem that support great biodiversity， bring absolutely no benefit but only serious harm to the environment.In fact， scientists have found that their loss and damage could mean oceans can absorb more CO2， slowing the buildup of this greenhouse gas in the atmosphere. 英 语·必修第一册（WY） 目 录 　　“It is a beneficial effect if you only care about the concentration of CO2 in the atmosphere，” says Lester Kwiatkowski at Sorbonne University in Paris， France.“But their reduction is harmful for biodiversity and leaves coasts exposed to rising seas，” he says. 　　How much the world will warm depends mainly on the level of CO2 in the atmosphere.So far， the land and oceans have absorbed around half of the extra CO2 we have emitted.A popular belief is that corals remove CO2 from seawater as they grow their structures.Actually， the process， called calcification （钙化）， is a net source of CO2， adding more CO2 英 语·必修第一册（WY） 目 录 than it removes.Observations also suggest rising seawater temperatures and oceans’ absorption of CO2 are causing coral reefs’ bleaching （白 化） and die-offs， so their release of CO2 is reduced. 　　Kwiatkowski and his team took published estimates of how corals will be affected by warming and CO2 in oceans and used a computer model to work out how this might change ocean carbon absorption in various situations.They conclude that the oceans could take up between 1％ and 5 ％ more carbon by 2100， and up to 13％ more by 2300.“But the precondition of the study is that corals aren’t able to adapt to the new 英 语·必修第一册（WY） 目 录 environment，” says Chris Jury at the University of Hawaii at Manoa.If Kwiatkowski’s team is correct， the amount of the carbon budget， which will lead to a given level of warming， is a little larger than currently thought. 　　“I think we would like our budgets to be as accurate as possible， even if we’re blowing through them，” says Kwiatkowski. 语篇解读：本文是一篇说明文。文章探讨了珊瑚礁消失可能对环境 有益的意外发现。科学家发现，珊瑚礁的减少可能使海洋吸收更多 二氧化碳，从而减缓温室气体在大气中的积累。 语篇解读：本文是一篇说明文。文章探讨了珊瑚礁消失可能对环境 有益的意外发现。科学家发现，珊瑚礁的减少可能使海洋吸收更多 二氧化碳，从而减缓温室气体在大气中的积累。 英 语·必修第一册（WY） 目 录 5. How does the author introduce the topic？（　　） A. Listing environmental benefits. B. Describing coral reef ecosystems. C. Explaining coral decline processes. D. Showing a contrast between beliefs. 解析：推理判断题。根据第一段内容可知，作者通过展示人们普遍认为的观点和科学家实际发现的情况之间的对比，来引入话题。 √ 英 语·必修第一册（WY） 目 录 6. What can be inferred about coral reefs from paragraphs 2 and 3？ （　　） A. Warmer oceans with CO2 help them grow. B. Ocean CO2 levels can be reduced by them. C. Climate has a very close link to coral reefs. D. Coral reefs prevent the rising of sea levels. √ 英 语·必修第一册（WY） 目 录 解析：　推理判断题。根据第三段首句和末句可知，大气中二氧化 碳含量影响世界变暖程度，而海水温度和海洋吸收二氧化碳又与珊瑚 礁相关，珊瑚礁又影响二氧化碳的释放，所以可以推断出气候与珊瑚 礁有着非常密切的联系。 英 语·必修第一册（WY） 目 录 7. Why does the research need to be improved？（　　） A. It predicts smaller carbon budgets. B. It ignores corals’ adaptation ability. C. It uses unproven computer models. D. It concludes carbon uptake increase. 解析：　细节理解题。根据倒数第二段中的But the precondition of the study is that corals aren’t able to adapt to the new environment可 知，这项研究需要改进的原因是它忽略了珊瑚的适应能力。 √ 英 语·必修第一册（WY） 目 录 8. What can be a suitable title for the text？（　　） A. Reefs in Crisis： A Warming World’s Effect B. Oceans Discovery： An Unexpected Finding C. Beyond the Bleaching： The Hidden Benefits D. Saving Coral Reefs： New Scientific Methods √ 英 语·必修第一册（WY） 目 录 解析：　标题归纳题。文章第一段先提出人们普遍认为珊瑚礁的 破坏和消失对环境只有危害，接着转折指出科学家发现其损失和 破坏可能使海洋吸收更多二氧化碳，减缓温室气体在大气中的积 累，后面又围绕这一发现展开讨论，包括研究过程、研究前提 等。C项（白化现象之外：那些未被察觉的益处）概括文章主要内 容，适合作文章标题。 英 语·必修第一册（WY） 目 录 Ⅱ.完形填空 　　（2026·黑龙江哈尔滨三中期末）I always give the same advice to travel enthusiasts： Wherever home is， that is where you should begin.However， I was  　9　 at following my own advice， for I have rarely explored my hometown — until now.Having canceled all my foreign trips， I  　10　 to Sweden to travel north from my hometown. 英 语·必修第一册（WY） 目 录 　　Unsurprisingly， my journey went smoothly， the scenery along the way breathtaking and picturesque， but my guide， Johan， opened my  　11　 to something else.One day， he asked me what I saw on a snowmobile path  　12　 with tall trees on both sides.“Trees？ Forests？” I answered.Johan shook his head， explaining， “Not a forest.A plantation.Forests no longer stand.The trees are planted by humans here.” He  　13　 that maybe soon， this plantation would be all that was left. 英 语·必修第一册（WY） 目 录 　　Johan was right.For over half a century now， the ancient forest that once seemed so  　14　 has continued to be cruelly cut down for biofuels and paper， and， in its place stand plantations of pine trees.Only a small part of the ancient forest  　15　， and that part grows smaller every year. 　　The Sám， a native people there， are facing an existential （存在主 义的）  　16　.Their lives and culture are  　17　 linked to the ancient forest and the reindeer that populate the region.However， the slow- growing lichen （地衣） and mushrooms， which the reindeer  　18　， are not found in any pine plantations.Without them， the reindeer population declines. 　19　， the death of one means the death of the other， and an  　20　 future for an entire people. 英 语·必修第一册（WY） 目 录 　　“We’re not  　21　 of nature， but part of it.” Johan’s words echoed in my mind as I looked at the  　22　 forest of the North in the rear-view mirrors （后视镜）.Too many of us have forgotten this truth — and with that forgetfulness， we may risk the  　23　 of not only the wild but also ourselves. 语篇解读：本文是一篇记叙文。文章讲述了作者回到瑞典家乡向北 探索，发现原始森林已被人造林取代，这威胁到依赖森林生态的萨 米原住民文化和驯鹿生存，作者不由反思人类与自然的关系。 语篇解读：本文是一篇记叙文。文章讲述了作者回到瑞典家乡向北 探索，发现原始森林已被人造林取代，这威胁到依赖森林生态的萨 米原住民文化和驯鹿生存，作者不由反思人类与自然的关系。 英 语·必修第一册（WY） 目 录 9.
