Dutch authors Thalia Verkade and Marco te Brömmelstroet are bothered by facts like these.In their new book Movement：How to Take Back Our Streets and Transform Our Lives，they call for a rethink of our streets and the role they play in our lives. Life on city streets started to change decades ago.Whole neighbourhoods were destroyed to make way for new road networks and kids had to play elsewhere.Some communities fought back.Most famously，a Canadian journalist who had moved her family to Manhattan in the early 1950s led a campaign to stop the destruction of her local park.Describing her alarm at its proposed replacement with an expressway，Jane Jacobs called on her mayor(市长) to champion “New York as a decent place to live，and not just rush through”．Similar campaigns occurred in Australia in the late 1960s and 1970s as well. Although these campaigns were widespread，the reality is that the majority of the western cities were completely redesigned around the needs of the motor car.The number of cars on roads has been increasing rapidly.In Australia we now have over twenty million cars for just over twenty-six million people，among the highest rate of car ownership in the world. We invest a lot in roads that help us rush through，but we fail to account for the true costs.Do we really recognise what it costs us as a society when children can't move safely around our communities? The authors of Movement have it right：it's time to think differently about that street outside your front door. 31．What can be a suitable title for the text? A．Why the Rush? B．What's Next? C．Where to Stay? D．Who to Blame? [自主解答]　A [解题导引] 第一步　读文章，分析各段大意 段落1(现象)：行人出行减少 → 家长开车送孩子。 段落2(论点)：书籍《Movement》提出街道需重新设计。 段落3(例证1)：加拿大记者简·雅各布斯反对拆除公园建高速路。 段落4(例证2)：澳大利亚类似运动未改变汽车主导的现状。 段落5(结论)：呼应荷兰作者的观点，明确呼吁 “重新思考街道功能”，总结前文，并升华主题。 第二步　串联各段落大意，提炼文章主旨 文章围绕 “城市街道设计过度迎合汽车需求，导致行人(尤其是儿童)出行受限，呼吁重新思考街道功能” 展开。 第三步　对比分析选项，确定答案 文章整体在批判城市规范中过度追求快速的交通而忽略安全、宜居的生活环境，A项Why the Rush？以反问形式点明主旨。 [技法归纳] 文章大意是作者在文章中所要表达的主要内容，是全文的核心思想，也是作者在文章中通过行文逻辑和各种细节来阐明的中心话题。掌握寻找文章主题的技巧，可以快速确定文章大意。常见设问形式： ①What is the text mainly about? ②What's the main idea of the text? ③What is mainly talked about in the text? 　(2024·新课标Ⅱ卷，C) We all know fresh is best when it comes to food.However，most produce at the store went through weeks of travel and covered hundreds of miles before reaching the table.While farmer's markets are a solid choice to reduce the journey，Babylon Micro-Fam (BMF) shortens it even more. BMF is an indoor garden system.It can be set up for a family.Additionally，it could serve a larger audience such as a hospital，restaurant or school.The innovative design requires little effort to achieve a reliable weekly supply of fresh greens. Specifically，it's a farm that relies on new technology.By connecting through the Cloud，BMF is remotely monitored.Also，there is a convenient app that provides growing data in real time.Because the system is automated，it significantly reduces the amount of water needed to grow plants.Rather than watering rows of soil，the system provides just the right amount to each plant.After harvest，users simply replace the plants with a new pre-seeded pod (容器) to get the next growth cycle started. Moreover，having a system in the same building where it's eaten means zero emissions (排放) from transporting plants from soil to salad.In addition，there's no need for pesticides and other chemicals that pollute traditional farms and the surrounding environment. BMF employees live out sustainability in their everyday lives.About half of them walk or bike to work.Inside the office，they encourage recycling and waste reduction by limiting garbage cans and avoiding single-use plastic.“We are passionate about reducing waste，carbon and chemicals in our environment，”said a BMF employee. 31．What does the text mainly talk about? A．BMF's major strengths. B．BMF's general management. C．BMF's global influence. D．BMF's technical standards. [自主解答]　A [解题导引] 第一步　读文章，概括文意 第一段，介绍BMF缩短了食物到餐桌的运输过程； 第二段至第四段，介绍BMF的创新设计系统及其相关优势； 第五段，介绍BMF员工在生活和工作中践行可持续发展。 第二步　析选项，斟酌判断 A BMF的主要优势。 本文第一段介绍BMF缩短了食物到餐桌的运输过程，第二至第四段介绍BMF的创新设计系统及其相关优势；最后一段介绍员工的可持续发展理念，该选项符合文意。 涵盖性强，覆盖全文 B BMF的综合管理。 文中仅简要提及BMF的自动化系统，目的是服务于介绍BMF优点，本选项以偏概全，不符合文意。 以偏概全， 断章取义 C BMF的全球影响力。 文中未提及相关内容。 无中生有， 生搬硬套 D BMF的技术标准。 文中未提及相关内容。 无中生有， 生搬硬套 第三步　对比选项，得出答案 对比选项发现，A项“巴比伦微农场(BMF)的主要优势”涵盖性强，覆盖全文。 [技巧归纳] 段落大意题是用准确、简练的语言把一个段落的主要意思明确而完整地表达出来。常见设问形式有： ①What is the...paragraph mainly about? ②What does the writer try to express in the...paragraph? ③What is the main idea of paragraph...? 　(2025·全国二卷，D) It should be noted that none of the items on wastED's menu was technically made from garbage.Instead，all the ingredients(配料) used were examples of meat cuts and produce that most restaurants would never consider serving.Things like kale ribs，fish collars，rejected sweet potatoes，and cucumber butts were all re-appropriated and，with the help of a number of good chefs，turned into excellent cuisine. 34．What is paragraph 5 mainly about? A．Why the ingredients were used. B．Which dishes were best liked. C.What the dishes were made of. D．Where the ingredients were bought. [自主解答]　C [解题导引] 第一步：分析各句大意 第一句否定菜品由垃圾制作； 第二句说明配料是餐厅通常不用的肉类和农产品； 第三句举例具体的配料及变成美味的过程。 第二步：串联各句内容，提炼段落大意 根据各句大意，可知本段主要讲述的是wastED菜单上的菜肴是由什么制成的。 第三步：对比选项，确定答案 选项 “What the dishes were made of.” 涵盖性强，覆盖全段。 [技法归纳] A (2025·武汉调研)A corn plant knows how to find water in soil with the very tips of its roots，but some varieties，including many used for developing high-output corn in the U．S.，appear to have lost part of that ability，according to a Stanford-led study.With climate change increasing droughts，the findings hold potential for developing more drought-resistant varieties of corn. The study，published in the journal Science，uncovers genetic mechanisms(遗传机制) behind root “hydropatterning”，or how plant roots branch toward water and avoid dry spaces in soil.In particular，the researchers discovered that ethylene，a plant hormone(激素) known to help bananas ripen，also influences how roots grow to seek water. For this study，the researchers developed a new，simplified way to study water sensitivity in roots.They found corn varieties adapted to hot and wet regions like Mexico were very good at making new root branches toward water and avoiding dry areas.In contrast，the varieties adapted to moderate regions of North America frequently grew roots randomly without distinguishing between dry and wet areas in the soil. “Interestingly，the plants that are better at sensing where the water is are also making deeper root systems，” said lead author Johannes Scharwies.“One idea is that if the plant doesn't waste time growing root branches into places where it doesn't find any water and nutrients，then it has more energy to grow deeper down where water is more likely.” Genetic analyses reveal two plant hormones，auxin and ethylene，play a role in how corn roots respond to water.While auxin was already known to help control this process，ethylene's involvement was a new discovery.In experiments with thale cress—a model plant often used in research—the researchers found auxin signaling promotes root branch development toward water，while ethylene stops branching when the root is exposed to air. Further research is needed to better understand the interaction of these genetic pathways before corn varieties can be developed with more drought-resistant root systems，but the findings highlight the significance of studying these localized responses at root tips，researchers said. [语篇解读]　本文是一篇说明文。文章介绍了斯坦福大学主导的一项研究揭示了植物根系如何通过遗传机制寻找水分。研究发现，乙烯和生长素这两种植物激素在玉米根系对水分的反应中起作用。这些发现为培育更具抗旱性的玉米品种提供了潜力。 1．What is the primary focus of the Stanford-led study? A．Drought-resistant corn varieties. B．Ethylene's effect on fruit ripening. C．Genetic regulation of root branching. D．Impact of climate change on plant roots. 解析　细节理解题。 根据第二段的“The study...uncovers genetic mechanisms (遗传机制) behind root ‘hydropatterning’，or how plant roots branch toward water and avoid dry spaces in soil.”可知，这项研究揭示了根系“向水性模式”背后的遗传机制，即植物根系如何朝着水分生长并避开土壤中的干燥区域。故研究的主要焦点是根系分支的遗传调控。 答案　C 2．What can be inferred from Johannes Scharwies' remarks? A．Plant hormones make a big difference to root growth. B．Nutrients guarantee better water-seeking root systems. C．Root branching conserves energy for higher production. D．Stronger hydropatterning is linked to greater root depth. 解析　推理判断题。根据第四段的 “Interestingly，the plants that are better at sensing where the water is are also making deeper root systems”可知，Johannes Scharwies 说那些更善于感知水源位置的植物，其根系系统也更深。由此可知，植物根系的“向水性模式”越强大，其根越深。 答案　D 3．What does paragraph 5 mainly talk about? A．Model plants in research. B．Hormones' role in root growth. C．Genetic analysis methods. D．Findings of previous research. 解析　段落大意题。 第五段首句是本段的主旨句，即基因分析显示，两种植物激素——生长素和乙烯——在玉米根系对水分的反应中发挥着作用，接着分别介绍两种植物激素所发挥的不同作用。所以第五段主要讲激素在根系生长中的作用。 答案　B 4．What does the last paragraph suggest future research do? A．Prioritize development of new corn varieties. B．Work out the mechanisms of genetic interactions. C．Concentrate merely on localized root responses. D．Expand practical applications of hydropatterning. 解析　细节理解题。 根据最后一段的 “Further research is needed to better understand the interaction of these genetic pathways before corn varieties can be developed with more drought-resistant root systems”可知，在培育出更具抗旱性根系的玉米品种之前，人们还需要进一步研究，以更好地了解这些遗传神经通路之间的相互作用。由此可知，未来的研究应该弄清楚遗传相互作用的机制，然后才能开发出更具抗旱性根系的玉米品种。 答案　B 二次精读 核心 词汇 Para.1：variety n.(植物、语言等的)变种，品种；多样化　drought-resistant adj.抗旱的 Para.2: uncover v.发现，揭露　ripen v.(使) 成熟 Para.3: simplify v.使简易，简化 sensitivity n.敏感性；灵敏度 moderate adj.适中的，中等的；温和的 distinguish v.区分，辨别 Para.4: nutrient n.养分，营养物 Para.5: involvement n.参与，卷入 Para.6: pathway n.神经通路；小道　 localized adj.局部的，小范围的 核心 短语 Para.3: in contrast相比之下 长难句 分析 One idea is that if the plant doesn't waste time growing root branches into places where it doesn't find any water and nutrients，then it has more energy to grow deeper down where water is more likely. 分析：本句为主从复合句。本句主干：one idea is that...；句中that引导表语从句，从句中if引导条件状语从句，在该从句中where引导定语从句，修饰先行词places；where water...likely为地点状语从句。 译文：一种观点认为，如果植物不浪费时间在没有找到水分和养分的地方生长根系分支，那么它就有更多能量向更深的地方生长，那里更有可能找到水源。 B (2025·太原模拟)Many people encourage competition and focus on success.“Giving up” is frowned upon.We are overjoyed at stories of people who persevered and succeeded.Friends and colleagues always encourage you to keep trying.“If at first you don't succeed，try，try again.” “Follow your dream! Winners never quit！” Perseverance is indeed important，to a limit.However，never take it too far.For one thing，goals and dreams might be beyond reach.Stories of achieving childhood dreams through perseverance might be uplifting，but they suffer from “selection bias”．Put simply，they are not informative，because nobody tells stories about the many people who persevered but failed after wasting a good part of their lives.It is indeed frustrating if you follow an unrealistic dream.For another，every road taken means another road is not taken.An unrealistic goal means missing out on other opportunities.What if everybody with the childhood dream of becoming an astronaut persistently kept trying forever? Winners always wisely choose what to quit and what to pursue. Recent studies have shown that being able to give up some goals and dreams and redirect your energy toward more reasonable ones is important for mental well-being and leads to higher quality of life in the long term.The psychological term is “goal disengagement”．If you are currently devoting too much time and effort to an unattainable goal，here are some hints that might help. First，do not tie a goal to your identity.Nobody can be defined by a single goal or interest.Besides，disengage from a goal but keep some of the effort.It's called “turning it into a hobby”．Few stamp and coin collectors desire to become professionals，yet many enjoy collecting.Last and most important，do not think of giving up as a failure，but as a choice.Your time is limited.Try new activities，rediscover previous interests，and revise your ambitions.Be honest with yourself about your chances，and choose the goals that best suit you.And remember that，when you give up a goal，you do not fail.You make a choice to free up your time for other possibilities. [语篇解读]　本文是一篇说明文。坚持不懈固然重要，但不能过度，因为有些目标可能遥不可及，坚持不切实际的目标意味着错过其他机会。研究表明，能够放弃一些目标并将精力转向更合理的目标对心理健康和提高生活质量很重要。 5．What result may “selection bias” bring to people? A．Setting self-limitation. B．Giving up more easily. C．Misjudging the situation. D．Ignoring successful stories. 解析　推理判断题。根据第二段中的 “Stories of achieving childhood dreams through perseverance might be uplifting...It is indeed frustrating if you follow an unrealistic dream.”可知，通过坚持不懈实现童年梦想的故事可能会令人振奋，但这存在“选择偏倚”；简单来说，这些故事并没有提供有用的信息，因为没人会讲述许多人浪费了生命中相当一部分时间去坚持却最终失败的故事，如果你追随一个不切实际的梦想，那确实会令人沮丧。这意味着“选择偏倚” 会让人们只看到成功的故事，从而错误判断形势，认为只要坚持就能成功。 答案　C 6．How can people benefit from “goal disengagement”？ A．By motivating their desire for success. B．By gaining a sense of self-satisfaction. C．By telling easy goals from difficult goals. D．By saving energy to focus on practical goals. 解析　细节理解题。根据第三段前两句可知，最近的研究表明，能够放弃一些目标和梦想，将精力转向更合理的目标对心理健康很重要，从长远来看会带来更高质量的生活，这在心理学上叫“目标脱离”。所以人们通过节省精力专注实际目标从“目标脱离” 中受益，“saving energy to focus on practical goals” 与文中的“redirect your energy toward more reasonable ones” 是同义表达。 答案　D 7．Which of the following may the author agree with? A．Accepting failure with ease does make sense. B．One can make a hobby out of an unattainable goal. C．Turn to professionals when realizing personal goals. D．Choosing a goal is more challenging than realizing it. 解析　推理判断题。根据第四段中的 “disengage from a goal but keep some of the effort.It's called ‘turning it into a hobby’”可知，从一个目标中脱离出来，但仍保留一些努力，这被称为 “把它变成一种爱好”。 答案　B 8．Which of the following is the best title for the text? A．Identity Crisis: Be True to Yourself B．Goals or Hobbies: Make Your Choice C．Never Say Never：The Key to Success D．Winners Do Quit: Be Wise About Your Goals 解析　标题归纳题。文章开篇提到人们鼓励竞争和坚持，接着指出坚持要有限度，过度坚持不切实际的目标会带来问题，然后说明“目标脱离”的重要性，并给出相关建议。所以文章主要讨论的是要明智地对待目标，懂得放弃不切实际的目标。故D项 “成功者会放弃：明智地对待你的目标” 最适合作本文标题。 答案　D 二次精读 核心 词汇 Para.2: uplifting adj.令人振奋的　bias n.偏见，成见　 informative adj.提供有用信息的，给予知识的 frustrating adj.令人懊丧的，令人沮丧的　 unrealistic adj.不切实际的 Para.3：hint n.建议，窍门；提示 Para.4：identity n.身份　define v.给……下定义，解释 revise v.改变，修正；复习 派生 词汇 Para.1：persevere v.坚持，孜孜以求→perseverance Para.2：n.不屈不挠，坚持不懈 核心 短语 Para.1：frown on/upon 不赞成，反对 (尤指某人的行为) Para.2：put simply 简单地说 miss out on sth错失获利 (或取乐等)的机会 Para.3：in the long term 长期来看 $
