Jaramillo's students live in neighborhoods where fresh food and green space are not easy to find and fast food restaurants outnumber grocery stores."The kids literally come to school with bags of snacks and large bottles of soft drinks,"she says."They come to us thinking vegetables are awful,dirt is awful, insects are awful."Though some are initially scared of the insects and turned off by the dirt,most are eager to try something new. Urban Sprouts'classes,at two middle schools and two high schools,include hands-on experiments such as soil testing,flower-and-seed dissection,tastings of fresh or dried produce,and work in the garden.Several times a year,students cook the vegetables they grow,and they occasionally make salads for their entire schools. Program evaluations show that kids eat more vegetables as a result of the classes."We have students who say they went home and talked to their parents and now they're eating differently,"Jaramillo says. She adds that the program's benefits go beyond nutrition.Some students get so interested in gardening that they bring home seeds to start their own vegetable gardens.Besides,working in the garden seems to have a calming effect on Jaramillo's special education students,many of whom have emotional control issues.“They get outside,”she says,“and they feel successful..” 专题一 阅读理解一闭 ②“穿珠连串法”确定文章标题 第一步读文章，理清结构 第一段 本文话题 开设Urban Sprouts项目 及 第二段 社区中，新鲜食物和绿色空间不易找到、快餐店数量 Urban Sprouts开设背景 超过杂货店。学生们对昆虫和泥土感到害怕和排斥 第三段 每年几次，学生们会烹任他们种植的蔬菜，有时候他 Urban Sproutsi课程简介 们甚至会为整个学校做沙拉 0 第四、五段 孩子们吃蔬菜的量增加；一些学生对园艺非常感兴趣： 项目评估 对学生们的情绪起到安抚的效果 第二步 析选项，斟酌判断 拯救学校花园。文章主要介绍的是Urban Sprouts项目如何帮助学生建立科学 移花接木。 A 技能、环境意识和健康的生活方式，而并非如何拯救学校花园。 偷换概念 体验乡村生活。Urban Sprouts是一个在低收入学校推广种植的项目，让学生们 无中生有， B 体验种植和环保，而并非关于乡村生活的体验 生搬硬套 培养爱吃蔬菜的人。Urban Sprouts项目旨在通过种植、烹任和试吃自己种植的 涵盖性强， 蔬菜，培养学生的科学技能、环保意识，以及健康的生活方式。 概括全文 改变当地风景。尽管这个项目可能在一定程度上改变了当地的风景，但这并非 以偏概全 文章的主要焦点。文章更多的是讲述项目如何影响和改变参与其中的学生 主次不分 038 第三步 对比选项得出答案 项为正确答案 27.What can be a suitable title for the text? ①设问方向：标题归纳 A.Rescuing School Gardens B.Experiencing Country Life C.Growing Vegetable Lovers D.Changing Local Landscape ·方法归纳· 1.利用4大技巧解题 关键词法 反复出现的词语，多次重复的观点就是体现主旨的关键词 主题句法 根据文章主题句，确定中心词充当标题 穿珠连串法 分析文章细节，确定共同点，如同穿珠般，串联细节共同点，确定标题 逆向法 根据四个选项，考虑其可能内容，对照原文，最相似者为最佳选项 2.结合3大特点解题 概括性 准确而又简短 好标题 针对性 3大特点 标题外延正好与文章内容相符 醒日性 能引发读者的阅读欲望 3.排除3种错误选项 概括范围窄，只含某个细节 排除3种 错误选项 概括范围太宽，超出文章内容 含文章中未提到的或找不到的信息 ☑一公网勾讲与练·高三二轮英语 考点3文章大意题一善用“3法” 文章大意题主要是测试考生对一篇文章的深层理解程度以及在速读中准确定位文章主旨大意的 能力。它要求考生在理解全文的基础上能较好地运用概括、判断、归纳、推理等逻辑思维的方法，对文 章进行高度概括或总结。 [典题呈现](2024·新课标Ⅱ卷阅读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-Farm (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 (to get the next growth cycle started. Moreover,having a system in the same building where it's eaten means zero emissions (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, 039 said a BMF employee. ②利用“高频词法”破解主旨大意 第一步读文章，理清结构 第一段 以新鲜食物的重要性及商店农产品运输的问题为引子，引出BMF公司，指出其可缩短运 输路程的优势。 第二段 强调BMF公司通过创新设计，能保证新鲜食材供应。 第三段 详细说明BMF公司依靠新技术，在节水等方面的优势。 第四段 指出其在可持续发展方面的优势。 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 BMF的主要优势。与原文对应，原文详细介绍了BMF如何减少运输距高、使用 涵盖性强， 新技术、节省水资源、减少排放和化学物质的使用，显示其优势 覆盖全文 无中生有， BMF的总体管理。原文中没有详细讨论BMF的管理层或管理策略 曲解文意 无中生有， C BMF的全球影响。原文未提及BMF的全球影响，仅从其技术和环保角度介绍 生搬硬套 BMF的技术标准。虽然文中提到了BMF使用的技术，但并未专门讨论技术 曲解文意， 标准。 张冠李戴 第三步 对比选项得出答案，答案选 专题一 阅读理解一团 31.What does the text mainly talk about? ①设问方向：文章大意 A.BMF's major strengths.

D.BMF's technical standards. ·方法归纳 破解文章大意三法 1.主题句法 解答文章大意题，找准文章的主题句是关键。下面介绍两种快速找出主题句的方法。 (1)根据文体和写作手法来定位主题句 主题句是 ①新闻报道类文章句首是主题句 ②首句语言精练，中间段多角度说明论证」 文章首句 且与尾段句子呼应，则首句是文章主题句 主题句在 文末 夹叙夹议类文章末段的议论部分隐含主题句 主题句在 文章首段是举例子或谈论个别现象时，主题 中间段 句则在后面的段落 最后观点 文章中出现了两种或两种以上的不同观点 为主题句 则最后的观点为主题句 (2)根据行文标志来定位主题句 转折词：句中如有but,however,in fact,.actually等词时，其后的内容往往是作者真正想要表达的 观点。 总结词：如therefore,thus,in short,conclude等，其后的内容往往是文章的主题句。 040 疑问句：若首段出现疑问句时，对该问题的回答可能是文章的主题句。 2.高频词法 全文中无明显主题句时，我们可以利用文章中的高频词。任何一篇文章都是围绕某个主题展开 的，因此，有的文章中最明显的特点之一是有一个反复出现的中心词，即高频词，也叫作主题词。抓 住了它，便容易抓住文章的中心。 3.逆向思维法 在两个选项看上去都十分正确无法选择时，试着从选项出发，想象一下如果自己以此选项来写 文章会写哪些内容，然后把它与文章的内容比较，接近的即为正确选项。 学以致用 能力生成 A her followers about her then 98-year-old friend.
