A (2025·河南许昌高一上期末) Last week，United Nations Secretary-General António Guterres coined a new term.The time of global warming has ended，he announced，and the time of “global boiling” has arrived. 语篇解读　本文是一篇说明文，联合国秘书长安东尼奥·古特雷斯提出了“全球沸腾”这一新术语，以描述当前气候变化的严重性。文章主要讲了这一术语的使用及其背后的原因，并介绍了人们对气候危机的认识和反应。 Ⅲ.主题语篇阅读 You can see why he said it.July was the hottest month on record globally.High temperatures and serious wildfires have swept across the Northern Hemisphere.Oceanic heatwaves are damaging the world’s third largest coral reef，off Florida.And as the levels of greenhouse gases continue to increase，it means many even hotter summers lie ahead. But critics have strongly disagreed with the phrase.At one level，“global boiling” is clearly an overstatement，but “global warming” is now far too weak a description.Many climate scientists have pushed for the term “global heating” to be used in preference.Similarly，phrases such as “climate crisis” haven’t received enough attention.That’s because many of us still feel we haven’t seen this crisis with our own eyes. But that is changing.In the past few years，extreme weather and related events have struck many countries.Australia’s Black Summer brought wildfires that burned an area equal to the size of the United Kingdom.Germany suffered serious flooding in 2021.The 2022 flood in Pakistan flooded large parts of the country.China has seen both droughts and floods.Terrible droughts have hit the Horn of Africa for many years.India has stopped rice exports due to damage from heavy rain. Critics of climate action often complain about what they see as the overuse of “crisis talk”.If everything is a crisis，nothing is a crisis. When Guterres uses deeply impactful phrases，he’s not inviting us to imagine a Hollywood-style disaster.What he’s hoping is to make people listen—and act—now we can see what climate change looks like. Are there better phrases to describe this? Possibly.Take the challenge yourself：can you think up a brief，correct phrase to cover worsening local- and regional-scale(区域级的) droughts，fires，typhoons and floods；damage to crops and food safety；water shortages；existential threats to coral reefs and low-lying communities? You can see how hard it is. 1.What made Guterres use the term “global boiling”？ A.The reviews from critics. B.The new scientific findings. C.The present serious situation. D.The future course of climate change. √ 细节理解题。根据第二段可知，Guterres使用“全球沸腾”这个短语是因为全球范围内出现了一系列的极端气候现象，目前形势严峻。故选C项。 解析 2.Why did such phrases as “climate crisis” fail to attract our attention? A.None of these phrases reflect the truth. B.Fewer crises have happened in recent years. C.Many phrases haven’t been mentioned publicly. D.Certain climate disasters haven’t happened to us. √ 细节理解题。根据第三段最后两句“Similarly，phrases such as ‘climate crisis’ haven’t received enough attention.That’s because many of us still feel we haven’t seen this crisis with our own eyes.”可知，“气候危机”等短语没能引起我们的注意是因为某些气候灾难没有发生在我们身上。故选D项。 解析 3.What does the author try to say by using “But that is changing.”？ A.But climate crises are worsening. B.But several crises will be solved. C.But people will face food shortages. D.But people are taking effective measures. √ 句意理解题。根据第三段最后一句可知，我们中的许多人觉得自己并没有亲眼见过气候危机；第四段中画线句下文讲了在过去的几年里，极端天气和相关事件袭击了许多国家。因此，作者用“But that is changing.”想说的是气候危机正在恶化。故选A项。 解析 4.What does the author think of Guterres’ saying “global boiling”？ A.It is beyond reality. B.It is just to scare people. C.It is reasonably acceptable. D.It is just to comfort the public. √ 观点态度题。根据最后两段可知，作者认为古特雷斯使用“全球沸腾”这一说法是为了让人们倾听并采取行动，因为现在我们可以看到气候变化的样子，且找到一个简洁又恰当的短语来概括目前的各种气候危机现象并不容易。因此，作者认为古特雷斯说“全球沸腾”是尚可接受的。故选C项。 解析 B(此篇精读) (2025·广东广州高一上期末) Whales are celebrated for being the largest and most intelligent creatures in the ocean.Now，biologists have discovered that they also capture tons of carbon from the atmosphere，a service with an economic value of US $1 trillion for all the great whales，according to a new study published by the International Monetary Fund.The study points out that protecting whales，normally viewed as a human good，also has a monetary motivation. 语篇解读　本文属于说明文，主要介绍了关于鲸鱼的一项新研究发现和鲸鱼碳捕获能力的经济价值，以及鲸鱼保护的紧迫性和意义。 “The carbon capture potential of whales is truly incredible，” said the report.“Our conservative estimates put the value of the average great whale at more than US $2 million，and easily over US $1 trillion for the current stock of great whales.” Whales absorb carbon in their bodies during their long lives，some of which stretch to 200 years.When they die，they sink to the bottom of the ocean，taking the carbon with them.According to the study，each great whale traps around 33 tons of carbon dioxide on average.A tree during the same period only contributes to 3 percent of the carbon absorption of the whale. Whale populations are today a small number of what they once were.It is estimated that there are slightly more than 1.3 million whales in the ocean，a quarter of their pre-whaling number of 4 to 5 million.Some species in particular，like the blue whale，are only 3 percent of what they used to be.“We can create financial methods to promote the restoration of the world’s whale populations，” said the report’s authors.“Rewards could help those who pay significant costs as a result of whale protection.” With the Paris Agreement coming into force and the effects of climate change ever more widespread，we must prevent the harm to whales.Researchers analyzed that unless new methods are put forward，it would take over 30 years to double the number of current whales，and several generations to return them to their pre-whaling numbers.“Society and our own survival can’t afford to wait this long，” they said. 5.What does the new study reveal about whales? A.They are money-makers for good. B.Their intelligence is unquestionable. C.They are a natural climate solution. D.Their survival is threatened by carbon. √ 推理判断题。根据第一段的“Now，biologists have discovered that they also capture tons of carbon from the atmosphere...according to a new study...”可知，新的研究表明，鲸鱼能从大气中捕获碳，即它们是一种纯天然的气候解决方案。故选C。 解析 6.Why is a whale compared with a tree in paragraph 2? A.To indicate all matter regarding green efforts. B.To illustrate whales are friendly to the oceans. C.To highlight whales’ carbon capture potential. D.To emphasize the importance of tree planting. √ 推理判断题。根据第二段的“According to the study，each great whale traps around 33 tons of carbon dioxide on average.A tree during the same period only contributes to 3 percent of the carbon absorption of the whale.”可知，把鲸鱼和树比较是为了强调鲸鱼的碳捕获潜力。故选C。 解析 7.What can be inferred from what researchers said in paragraph 4? A.Climate change intensifies. B.Whale populations stay low. C.Our survival is endangered. D.Whale protection is a priority. √ 推理判断题。根据第四段最后两句可知，需要使用新的方法使鲸鱼的数量尽快恢复，否则会威胁社会和人类自身的生存，因此保护鲸鱼是当务之急。故选D。 解析 8.What is the most suitable title for the article?
