from the sun’s radiation， new research shows． 　　The study suggests that over the past 75 years， the ultraviolet （UV） pigments （紫外线色素） in flowers have increased in response to rising temperatures and the thinning ozone layer （臭氧层）．The flowers won’t look any different to humans， but insects consider the higher levels of UV pigments as a darker color， which could be confusing when they try to find out colorful flowers to land on． 　　The UV－absorbing pigments in flowers work like sunscreen and protect sensitive cells from harmful radiation， Matthew Koski， a plant ecologist at Clemson University， says．He and his team hoped to determine if changes in pigments were a result of environmental change — and if so， what were the plants responding to？ The team collected dried， pressed plants across North America， Australia and Europe．In total， they studied 1，238 samples from 42 different species dating back to 1941.Then， using a UV－sensitive camera， they photographed flower petals from each species．Next， they paired the photographs with the historic local temperature and ozone level data from the time the plant was picked to see how the pigment level changed over time． 　　The researchers found that the changes in pigments differ between species， a result of the flowers structure．Flowers with open， exposed pollen had more UV－absorbing pigments when ozone levels were low and radiation was high．But flowers with pollen surrounded by the petal responded to temperatures， not ozone levels． 　　As climate change continues to intensify， these changes in flowers color can affect plant－insect interactions．When the whole flowers get darker， insects might miss the flowers entirely．“This has a negative influence on plant reproduction，” Koski says． 1.What is the cause of flowers color changing according to the research？（　　） A．The impact of the climate crisis．　 　 B．The loss of natural habitats． C．The harm of nuclear radiation．　 　 D．The thickening of the ozone layer． 2.How did Koski’s team get their findings？（　　） A．By collecting photographs of flowers from different species． B．By analyzing how levels of UV pigments change over time． C．By collecting abundant samples from various species． D．By analyzing historic local temperature and ozone level data． 3.What can we learn about the change in pigments？（　　） A．It exists in flowers with exposed pollen only． B．It responds to temperatures and sea levels． C．It remains the same regardless of species． D．It varies depending on the flowers structure． 4.What is Koski’s attitude toward the change in flowers color？（　　） A．Concerned．　 　B．Indifferent． C．Unclear．　 　D．Optimistic． B 　　（2026•四川成都期中）In oceans across the globe， a tiny jellyfish （水母） species shows a remarkable death－defying ability．After reaching sexual maturity， this jellyfish can turn back into its young form and then mature again — a process similar to a butterfly turning back into a caterpillar and then changing into a butterfly again．The deep－sea creature’s life cycle could theoretically be repeated forever， earning this species， called Turritopsis dohrnii （灯塔水母）， the nickname： the “immortal jellyfish”． 　　Like a typical jellyfish， T．dohrnii begins its life as a free－floating larva （幼体） and matures into a branching， plant－like polyp （水螅体） ．From there， multiple young jellyfish grow out of the polyp and turn into adults．However， the difference is that when an adult T．dohrnii is damaged or stressed， instead of dying， it absorbs its own arms and becomes a blob that settles to the sea floor．Over the next day and a half， this blob transforms into a new polyp， which can then form more jellyfish．Therefore， though T．dohrnii may be eaten by predators， it does not die of old age． 　　A new study compared T．dohrnii to T．rubra， a related jellyfish species that undergoes normal aging．Compared to its relative， researchers found that T．dohrnii has twice as many genes that repair and protect DNA．This allows T．dohrnii to generate more restorative proteins．Researchers also found differences in several other genes， including those associated with replication and the stem cell population．These differences may be key to the jellyfish’s immortality． 　　Researchers say these findings could help humans — but not in the exact same way．They believe their study could help find better answers to the many diseases associated with aging．They also hope a better understanding of these jellyfish genes might inspire regenerative medicine for humans． 5.Why does the author mention a butterfly in the first paragraph？（　　） A．To explain the aging process of T．dohrnii．　 　B．To emphasize the small size of T．dohrnii． C．To present the living habits of T．dohrnii．　 　D．To show the special life cycle of T．dohrnii． 6.How does T．dohrnii differ from other jellyfish species？ （　　） A．It can avoid dying of old age．　 　B．It goes through a polyp stage． C．It can transform to defend itself．　 　D．It has very few natural enemies． 7.What is paragraph 3 mainly about？（　　） A．The specific findings of the new study．　 　 B．The social significance of the research． C．The detailed procedures of the research．　 　D．The possible limitations of the new study． 8.What can be a suitable title for the text？（　　） A．Predators of the Deep： How the “Immortal Jellyfish” Survives through Various Conditions B．Unlocking Immortality： The Genetic Secrets of the Jellyfish That Reverses Aging C．From Polyp to Jellyfish： The Unique Lifecycle of a Deep－Sea Jellyfish D．Human Immortality on the Horizon？ Lessons from a Jellyfish Ⅱ．阅读七选五 　　（2026•陕西榆林期中） Soilless farming， as the name implies， is a type of farming where plants are cultured and grown without the use of the soil.9.　　 With this method， crops can be planted almost everywhere． 　 　Due to lacking originality， conventional farming has many processes and requires the manure （肥料） of chemical mixtures to make the soil rich in nutrients．Soilless farming has less workload and can enhance growth.10.　　 Their needs are met throughout life， from seeds to ripe fruit． 　　In many soilless farming systems， water is recycled and reused until the plants are ready to harvest．Hence， soilless farming is an alternative to dry regions．Additionally， it reduces the physical labor and energy required from workers.11.　　 　 　By following standardized steps throughout the entire production process， soilless farming can supply crops to the market every day， meeting consumers’ needs.12.　　 They will begin growing crops locally all year round．In this way， even seasonal produce can be harvested anytime． 　　13.　　 The rate at which pathogens （病原体） attack the farm will be zero as a result of how the planting environment is concerned， and if the pathogen ever attacks， the infected plant will be easily separated to avoid infecting the farm as a whole．Developed countries in the world are expected to adopt this mode of farming because doing so reduces the level of food importation and increases the availability of food in the country． A．The quality of the harvested food may be controlled． B．However， soil farming requires more workload． C．This helps them achieve higher profits while keeping costs very low． D．After all， food imports might pollute the environment． E．Nutrients are provided to the plants， majorly in liquid form． F．Countries relying on food imports see how productive this farming method is． G．It is also a systematic technique for growing plants without soil as a rooting environment． Ⅲ．应用文写作 　　（2026•四川南充期中）你校英文报正在举办以“Green Living： Start with Me”为主题的征文活动。请你写一篇短文参与此活动，内容包括： 　　（1）你对绿色生活的理解；

层级二　能力练 Ⅰ． 语篇解读：本文是一篇说明文。最新研究表明，为了适应气候变化，一些花的颜色正在变深。 1.A　细节理解题。根据第一段可知，为了适应气候变化，一些花朵正在加深颜色以保护自己免受太阳辐射，所以花朵颜色变化的原因是气候危机的影响。 2.B　细节理解题。根据第三段可知，研究团队将紫外线敏感相机拍摄的花瓣照片与采摘植物时的当地历史温度和臭氧水平数据配对，分析紫外线色素水平如何随时间变化，从而得出研究结果。 3.D　细节理解题。根据第四段第一句可知，色素的变化因物种而异，是花朵结构导致的，即色素变化取决于花朵的结构。 4.A　推理判断题。根据最后一段中Koski说的话可知，Koski 认为花朵颜色变化对植物繁殖有负面影响，说明他对花朵颜色变化持担忧态度。 语篇解读：本文是一篇说明文。文章主要介绍了灯塔水母这一特殊的水母种类，它具有一种非凡的逆生长能力，理论上可以无限循环其生命周期，因此被称为“不老水母”。 5.D　推理判断题。 根据第一段中的After reaching sexual maturity ．．．changing into a butterfly again．可知，作者通过描述蝴蝶变回毛毛虫这一假设的类比，是为了展示灯塔水母特殊的生命周期。 6.A　细节理解题。 根据第二段中的Therefore， though T．dohrnii may be eaten by predators， it does not die of old age．可知，灯塔水母与其他水母的不同之处在于它具有避免因衰老而死亡的能力。 7.A　段落大意题。 根据第三段对DNA修复基因、修复功能蛋白质以及干细胞群相关基因差异的描述可知，本段主要介绍了关于灯塔水母“永生”机制的新研究的具体发现。 8.B　标题归纳题。 通读全文可知，文章围绕灯塔水母逆转衰老的独特现象展开，并重点解释了其背后的基因修复秘密。故B项最适合作文章标题。 Ⅱ． 语篇解读：本文是一篇说明文。文章介绍了无土栽培的定义、优势及应用前景。 9.G　空前提到无土栽培，顾名思义，是一种不借助土壤来培育和种植植物的耕作方式。G项（它也是一种不将土壤作为根系环境的系统性植物种植技术）承接上文，对无土栽培的定义作了进一步的专业解释，衔接自然。 10.E　空前提到无土栽培工作量更少且能促进生长，空后提到植物在整个生命周期里所需的养分都能得到满足。E项（营养物质主要以液体形式提供给植物）解释了植物需求如何被满足，既承接了无土栽培的种植特点，又呼应了下文的Their needs are met throughout life。 11.C　空前讲到无土栽培减少了工人所需的体力劳动和精力，这属于降低人力成本的优势。C项（这有助于他们在保持低成本的同时获得更高的利润）符合语境，C项中的This指代上文提到的减少体力劳动和精力的做法，“低成本、高利润”是该优势带来的合理结果。 12.F　空后提到他们将开始全年在本地种植作物，They应指代某个特定群体。F项（依赖粮食进口的国家看到了这种种植方式的高生产力）符合语境，F项中的Countries relying on food imports与下文的They相对应，且“本地种植”正是解决“依赖进口”的有效方式，衔接通顺。 13.A　空后提到得益于对种植环境的把控，病原体侵袭农场的概率将降为零。A项（收获的食品质量可以得到控制）对应了无土栽培环境的可控性，病原体侵袭少直接保障了食品质量，与下文形成因果关联。 Ⅲ． Green Living： Start with Me 　　Green living means living in a way that is environmentally friendly and sustainable．It involves saving resources， reducing waste， and protecting our planet．I believe green living benefits the environment， health， and economy． 　　To practice green living in my daily life， I will start with small steps．For example， I will use reusable bags instead of plastic ones when shopping．I will also turn off the lights and water taps when they aren’t in use to save energy and water．Moreover， I will try to walk or bike more often instead of driving， which can reduce air pollution and save money． 　　I hope more people will join me in practicing green living and protecting our planet． 4 / 4 学科网（北京）股份有限公司 $
