Ⅰ.阅读理解(共12小题；每小题2.5分，满分30分)
A
(2025·浙江金华高三一模) The story of the Forest of Immortal Stories begins in 2019, when Cojocaru lost his wife to cancer. Cojocaru suffered constant depression; as a solution, his doctor told him to walk in the countryside, 6，000 or more steps a day.
Cojocaru had grown up in Nucsoara, but only as he walked the hills did he notice the trees: giant beeches (山毛榉), some as old as 500 years. Their beauty and strength revived him, and he felt as if they had adopted him.
Indeed, generations of villagers gathered firewood from the trees, trimming (修剪) the branches. Where the trees were trimmed, new shoots appeared, branched, grew and were trimmed again, year after year for centuries. The practice allowed the trees to continue bearing nuts, which the villagers fed to their pigs to fatten them up. “The power of these trees is mindblowing，” said Cojocaru. 5，000 beeches still grow around Nucsoara, the highest concentration in Europe. But logging and changing uses of the land pose a threat. Bark beetles (蠹虫) are moving in, too.
Together with a conservation organization, Cojocaru began the plan to protect the beeches and draw ecotourism to Nucsoara. 2，544 trees were identified and each was given a number plate, photographed through the seasons and marked on a digital map. The trees are offered for adoption on a website—although as Cojocaru insists, the tree adopts the person, not the other way around.
So began the project—the Forest of Immortal Stories. For a modest fee, people can attach their own stories to a tree. When visited in person, the tree reads the narrative back through a QR code. For example, No.44 is Ana Branza, a Romanian fencing champion who won her first national title at age 15.
No.2，544 is Cojocaru. “I learn from them. I get a sense that they are old men who are very wise and want me to do good.” Cojocaru said of the trees.

(2025·辽宁七校名校协作体期中) Almost half a billion small, cheap electrical everyday items from headphones to handheld fans ended up in landfill in the UK in the past year, according to research.
The not-for-profit organisation Material Focus, which conducted the research，said the scale of the issue was huge and they wanted to encourage more recycling.
More than half a billion cheaply priced electronic goods were bought in the UK in the past year alone—16 per second. Material Focus findings showed that of these items，471m were thrown away. This included 260m disposable vapes (电子烟), 26m cables, 29m LED, solar and decorative lights, 9.8m USB sticks, and 4.8m miniature fans.
Scott Butler, executive director at Material Focus, described it as “fast tech”．He said: “People should think carefully about buying some of the more silly items in the first place.” He said the items people bought were often “cheap and small”， and that consumers may not realise they contain valuable materials that could be saved if recycled.
Small electricals can contain precious materials including copper, lithium and stainless steel. These components can be recycled and used in wind turbines, medical devices and electric vehicles. Material Focus said that while people were used to the idea of recycling larger electrical items such as fridges, lots of smaller devices were left unused in houses.
Butler said ：“We want to get the message across that anything with a plug, battery or cable can be recycled and there's somewhere near you to do it. The scale of the issue is huge, but there's an easy solution—just as the trend for recycling and repurposing fashion has grown and grown, we want to encourage the nation to recycle fast tech, guilt-free and fuss-free.”
Material Focus said that when consumers bought a cheap item, they saw it as disposable. They estimate that UK citizens spent more than ￡2.8bn on these cheap products in the past year. The non-profit group described it as “the tip of the iceberg” when it comes to the growing issue of wasted electricals in the UK. More than 100，000 tons of waste electricals are thrown away every year, and there are 880m electrical items of all kinds lying unused in UK homes.
5．What can we infer from Butler's words in Paragraph 4？(　　)
A．Cheap items don't deserve consumers' careful use.
B．Low-quality electrical goods are easy to be recycled.
C．Consumers should stop buying these “fast tech” in the first place.
D．Valuable materials can be found in these cheap and small electrical goods.
答案：D　
解析：细节理解题。根据第四段中“He said the items people bought were often ‘cheap and small’， and that consumers may not realise they contain valuable materials that could be saved if recycled.”可知，从第四段巴特勒的话中我们可以推断出在这些便宜的小电器产品中可以找到有价值的材料。故选D。
6．What did Butler appeal to people to do？(　　)
A．They'd better spread the idea of “fast tech”．
B．They'd better recycle small devices as well as larger ones.
C．They'd better set up somewhere near them to do the recycling.
D．They'd better catch the trend of disposing small and cheap items.
答案：B　
解析：推理判断题。根据倒数第二段中“‘We want to get the message across that anything with a plug, battery or cable can be recycled and there's somewhere near you to do it.’”可推知，巴特勒呼吁人们最好回收小型设备和大型设备。故选B。
7．What's the main idea of the passage？(　　)
A．Tons of small and cheap electrical items are thrown away.
B．Legal efforts should be made to ban small electrical items.
C．“Fast tech”—the future generation.
D．Recycling valuable materials from electronics is urgent.
答案：A　
解析：主旨大意题。文章介绍了在过去的一年里，大量日常小电器被扔进了英国的垃圾填埋场。Material Focus表示，这个问题非常严重，他们希望鼓励更多的回收利用这些小电器。第一段中讲到“Almost half a billion small, cheap electrical everyday items from headphones to handheld fans ended up in landfill in the UK in the past year, according to research.”可知，这篇文章的中心思想是成吨的小而便宜的电器被扔掉。故选A。
8．Where is the text most probably taken from？(　　)
A．A book review. B．A philosophical textbook.
C．A science magazine. D．An electronic book.
答案：C　
解析：推理判断题。根据第一段中“Almost half a billion small, cheap electrical everyday items from headphones to handheld fans ended up in landfill in the UK in the past year, according to research.”可推知，这篇文章最有可能来自于一本科学杂志。故选C。
C
(2025·山西三晋名校联合考试) The warning signs are all there: record-breaking heat, failing health, vanishing ice sheets, and more unpredictable weather. And yet we're still pumping increasing amounts of greenhouse gasses into the atmosphere, threatening our very survival.
A new study by an international team of experts highlights how global methane (甲烷) emissions have been rising rapidly since 2006, particularly since 2020.We'll perpetuate the trend unless we do something extreme very soon. The study's authors have then outlined some strategies countries can use to take action, and developed an online tool to help with this.
This continual climb in methane emissions is largely due to the ongoing use of fossil fuels in preference to cleaner alternatives. It's directly produced by oil, gas, and coal drilling and processing. The increasing release of methane from natural wetlands, caused by a hotter climate, is now also contributing.
“Worldwide efforts to limit climate change are rightly focused on carbon dioxide (CO2), the primary driver，” the team writes in their published paper. “However, since humanity has failed to adequately address climate change for several decades, keeping warming below agreed goals now requires that we address all major climate pollutants.”
There is currently much less methane in our atmosphere than CO2, but methane is a stronger greenhouse gas. We know that methane is a major contributor to the warming of the world, trapping heat like CO2 does. It also contributes to the formation of ozone at ground level, increasing the risk of death through diseases related to lungs and heart.
All these different methane sources need to be urgently looked at. The study finds: Methane reduction targets should be applied alongside CO2 reduction targets, and new technologies and policies need to be introduced.
“A change in thinking from governments and organizations is required，” said one of the researchers. “We have created a new online tool to help with the reduction of methane emissions. This tool should help to target reductions effectively and monitor expected improvements.”
9．What does the underlined word “perpetuate” in Paragraph 2 mean？(　　)
A．Prevent. B．Control. C．Continue. D．Recognise.
答案：C　
解析：词义猜测题。根据文章画线词上文“A new study by an international team of experts highlights how global methane (甲烷) emissions have been rising rapidly since 2006, particularly since 2020.”和下文“the trend unless we do something extreme very soon”可知，如果不采取行动，全球甲烷排放量迅速上升的这种趋势会持续下去。由此可知，画线词perpetuate的意思是“继续，持续”。故选C。
10．What is the main cause of the continuous rise in methane emissions？(　　)
A．More emission of CO2.
B．Ongoing animal farming.
C．Continued use of fossil fuels.
D．Modern agricultural development.
答案：C　
解析：细节理解题。根据文章第三段中“This continual climb in methane emissions is largely due to the ongoing use of fossil fuels in preference to cleaner alternatives.”可知，甲烷排放量持续上升的主要原因是持续使用化石燃料。故选C。
11．According to the study, what may increasing methane emissions bring about？(　　)
A．Health risks caused by ozone.
B．Limiting the formation of ozone.
C．A decrease in global temperatures.
