专题一　阅读理解 第3讲　主旨大意题 任务一　探寻命题规律 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 (2024·新课标Ⅰ卷，B)“I am not crazy，” says Dr. Farber, shortly after performing acupuncture (针灸) on a rabbit. “I am ahead of my time.” If he seems a little defensive, it might be because even some of his coworkers occasionally laugh at his unusual methods. But Farber is certain he'll have the last laugh. He's one of a small but growing number of American veterinarians (兽医) now practicing “holistic” medicine—combining traditional Western treatments with acupuncture, chiropractic (按摩疗法) and herbal medicine. 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 Farber, a graduate of Colorado State University, started out as a more conventional veterinarian. He became interested in alternative treatments 20 years ago when he suffered from terrible back pain. He tried muscle-relaxing drugs but found little relief. Then he tried acupuncture, an ancient Chinese practice, and was amazed that he improved after two or three treatments. What worked on a veterinarian seemed likely to work on his patients. So, after studying the techniques for a couple of years, he began offering them to pets. 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 Leigh Tindale's dog Charlie had a serious heart condition. After Charlie had a heart attack, Tindale says, she was prepared to put him to sleep, but Farber's treatments eased her dog's suffering so much that she was able to keep him alive for an additional five months. And Priscilla Dewing reports that her horse, Nappy, “moves more easily and rides more comfortably” after a chiropractic adjustment. Farber is certain that the holistic approach will grow more popular with time, and if the past is any indication, he may be right: Since 1982, membership in the American Holistic Veterinary Medical Association has grown from 30 to over 700. “Sometimes it surprises me that it works so well，” he says. “I will do anything to help an animal. That's my job.” 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 24. What do some of Farber's coworkers think of him? A.He's odd.　　 B.He's strict. C. He's brave. D.He's rude. 25.

And at first it is, says Jaramillo, who with another teacher started Urban Sprouts, a school garden program at four low-income schools. The program aims to help students develop science skills, environmental awareness and healthy lifestyles. 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 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. 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 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.” 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 27. What can be a suitable title for the text? A.Rescuing School Gardens B. Experiencing Country Life C. Growing Vegetable Lovers D. Changing Local Landscape [技法点拨] 1. 明确一个好的标题应具备三大特点 (1)概括性——准确而又简短，常用一个短语或一句话； (2)针对性——标题外延正好与文章内容相符； (3)醒目性——新颖奇特，能引发读者的阅读兴趣。 √ 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 2. 巧用四大技巧确定文章标题 (1)关键词法：多次出现的词语或观点往往是体现主旨的关键词； (2)主题句法：根据文章主题句，确定中心词充当标题； (3)穿珠连串法：从文章细节中找共同点，如同穿珠般串联细节共同点，确定标题； (4)逆向思维法：考虑四个选项的可能内容，对照原文，最相近者为最佳标题。 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 3. 掌握三大解题步骤 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 [技法运用] 第一步： 读文章，理清结构 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 第二步： 细揣摩，概括文意 本文是一篇记叙文。文章主要讲述了学校菜园项目Urban Sprouts的启动背景、目的、内容和意义。 第三步： 析选项，斟酌判断 选项 选项意思 选项定位 A 拯救学校菜园 以偏概全 B 体验乡村生活 以偏概全 C 蔬菜种植爱好者 正确概括 D 改变当地景观 无中生有 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 根据第一段中的“And at first it is, says Jaramillo, who with another teacher started Urban Sprouts, a school garden program at four low-income schools. The program aims to help students develop science skills, environmental awareness, and healthy lifestyles.”和最后一段中的“Some students get so interested in gardening that they bring home seeds to start their own vegetable gardens.”以及其他内容可知，文章主要讲述了Jaramillo等老师在低收入学校发起的培养学生科学能力、环保意识以及养成健康生活方式的Urban Sprouts菜园项目，让学生种植蔬菜，对学生影响深远。因此推断C项“蔬菜种植爱好者”能概括文意，最适合作本文的标题。故选C。 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 在解答文章大意题时，首先，仔细阅读文章，理清文章结构；然后，标出能概括文章大意的主题句或主题段、高频词以及关键信息，并采用恰当的方法概括文意；最后，分析选项，斟酌判断，选出最佳答案。 类型二　文章大意题——明晰主题知文意 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 (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-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. 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 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 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 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. 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 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. √ 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 [技法点拨] 1. 主题句或主题段法 找出主题句或主题段可采用下面的方法： (1)依据文体和写作手法来定位主题句或主题段 在演绎类议论文、先议后叙的记叙文、新闻报道中，通常文章的第一句或第一段就是主题句或主题段。在归纳类议论文中，前面的内容作为铺垫，最后一句或最后一段是对文章的概括和总结；在先叙后议的文章中，最后一句或最后一段则是作者对所述事件的议论，是文章的精髓。 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 在“总—分—总”结构的文章中，首段和尾段都是主题段；在“分—总—分”结构的文章中，主题段会出现在文章的中间。找到文章的主题句或主题段，然后根据主题句或主题段所表达的意思，结合整篇文章的内容，概括出文章的大意。 (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等时，其后的内容往往是作者真正想要表达的观点 总结词 句中如有therefore, thus, in short, conclude等，其后的内容往往是文章的主题 疑问句 若段首出现疑问句时，对该问题的回答可能是文章的主题 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 2. 高频词法 任何文章都是围绕某个主题展开的。当文章中没有明确的主题句时，可以从文中的每个段落中寻找反复出现的中心词，即高频词(也叫主题词)。这个高频词往往体现了文章的主旨大意。 3. 梳理故事主线法 记叙文通常讲述一个有趣的故事或某一段印象深刻的经历。记叙类文章都有一个主线，全文围绕这个主线组织材料。如果能找到全文的主线，理清故事的人物以及故事发生的时间、地点、经过和最终的结果，就能概括出文章的大意。从分析文章的结构入手，把握全文的主线，理清句与句、段与段之间的逻辑关系，最后归纳出文章的主旨大意。 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 [技法运用] 第一步：读文章，理清结构 第二步：细揣摩，概括文意 本文是一篇说明文。文章主要介绍了一家旨在为人们提供新鲜食材的BMF公司的一些主要优势。 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 第三步：析选项，斟酌判断 通读全文可知，文章主要介绍了BMF 缩短农产品的运输距离，是一种创新设计；它还可以节省水，实现零排放，避免使用农药和其他化学物质，满足城市居民对新鲜蔬菜的需求。以上内容都是BMF的优点，所以A项“BMF's major strengths.”能够概括文章主旨。故选A。 选项 选项意思 选项定位 A BMF的主要优势 正确概括 B BMF的全面管理/经营 以偏概全 C BMF的全球影响 无中生有 D BMF的技术标准 以偏概全 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 在解答段落大意题时，首先，仔细阅读段落内容，了解段落结构；然后，标出段落主题句或体现段落大意的关键信息；最后，根据段落主题句或关键信息，仔细分析选项，选出最佳段落大意。 类型三　段落大意题——明确结构悉段意 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 (2023·新课标Ⅰ卷，D) This effect capitalizes on the fact that when people make errors, those errors aren't always the same. Some people will tend to overestimate, and some to underestimate. When enough of these errors are averaged together, they cancel each other out, resulting in a more accurate estimate. If people are similar and tend to make the same errors, then their errors won't cancel each other out. In more technical terms, the wisdom of crowds requires that people's estimates be independent. If for whatever reasons, people's errors become correlated or dependent, the accuracy of the estimate will go down. 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 32. What is Paragraph 2 of the text mainly about? A.The methods of estimation. B. The underlying logic of the effect. C. The causes of people's errors. D. The design of Galton's experiment. √ 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 [技法点拨] 1. 分析段落结构，寻找段落主题句，概括段落大意 一篇文章的段落大意是由主题句体现的，在大多数情况下，段落的首句就是该段的主题句。因此，根据主题句便可归纳出该段的大意。可采用下列方法快速找到主题句。 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 2. 根据关键信息归纳、总结和概括段落大意 有时，作者不直接写出主题句。对于没有主题句的段落，要根据各种暗示，结合段落中多次出现的词语对段落的主体内容进行归纳、总结和概括。 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 [技法运用] 第一步： 读原文，理清结构 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 第二步： 细揣摩，概括段意 本段主要解释了为什么大量独立估算的平均值在某些情况下可以相当准确，这是由于人们估算的误差并不总是相同的，当这些误差足够多，并被平均开来时，它们会互相抵消，从而得出更准确的估算值，这就是群体智慧效应的基本逻辑。 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 第三步： 析选项，斟酌判断 故选B。 选项 选项意思 选项定位 A 估算方法。 以偏概全 B 效应的内在逻辑。 正确概括 C 人们犯错误的原因。 无中生有 D 高尔顿实验的设计。 无中生有 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 任务三　深化迁移应用 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 A It's not hard to be poetic about the broad and deep benefits of spending time in natural spaces, from amazing national parks to the simple loveliness of a walk around a city park or tree-lined neighbourhood street, and some time working in the dirt of your own garden. A new study from researchers at Clemson University has found another benefit of simply putting your body in a natural space: it can lower the amount of money you spend on health care. 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 “The mechanisms linking nature and health are very diverse，” said Matthew Browning, the principal investigator on the study, “but the benefit is believed to be in part because being in green space can decrease stress, promote healthy behaviours and enable you to breathe fresh air.” Browning and his team used satellite data to investigate how much green space was within 250,500 and 1,000 metres of five million northern California residents who were insured by Kaiser Permanente. They then determined the costs the insurance company paid out to those same members over a two-year period. They took into account age，gender，race and a number of neighbourhood characteristics including population density and education levels. 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 Even with all these factors included into their analysis, the researchers found that those who lived near the most green space had an average of $374 less per year in health care expenses compared to those who lived farther from natural spaces. The researchers hope their findings will support public policies that prioritise (优先考虑) natural elements in residential areas. For you, maybe this learning will inspire you to plant a tree or a potted flower today—or create a beautiful garden to enjoy, with a view of some health-giving, green goodness. 【语篇解读】本文是一篇说明文。文章主要介绍了一项新的研究发现，该研究表明人们处于自然环境中可以减少医疗保健的费用。 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 1.

A.Getting Close to Nature Keeps Us Happy B. It's Unnecessary to Invest Much in Health C. It's Not Hard to Keep Fit for City Residents D. Being in Nature Reduces Health Care Cost D　标题归纳题。根据第二段的内容以及第五段的内容可知，本文主要介绍了一项新的研究发现，该研究表明人们处于自然环境中可以减少医疗保健的费用。所以“Being in Nature Reduces Health Care Cost”作为文章标题最为合适。故选D。 √ 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 B (2024·滨州二模)Some people today might be early risers because of DNA they take after Neanderthals tens of thousands of years ago, suggests new research. When early humans migrated from Africa to Eurasia roughly 70,000 years ago, some of them mated with Neanderthals, who had already adapted to the colder, darker climates of the north. The ripple (涟漪) effects of that intermating still exist today: Modern humans of non-African ancestry (血统) have between 1 and 4 percent Neanderthal DNA. Some of that DNA relates to sleep more specifically, the internal body clock known as the circadian rhythm. 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 For the new study, researchers compared DNA from today's humans and DNA from Neanderthal fossils (化石). In both groups, they found some of the same genetic variants involved with the circadian rhythm. And they found that modern humans who carry these variants also reported being early risers. For Neanderthals, being “morning people” might not have been the real benefit of carrying these genes. Instead, scientists suggest, Neanderthals' DNA gave them faster, more flexible internal body clocks, which allowed them to adjust more easily to annual changes in daylight. This connection makes sense in the context of human history. When early 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 humans moved north out of Africa, they would have experienced variable daylight hours—shorter days in the winter and longer days in the summer—for the first time. The Neanderthals' circadian rhythm genes likely helped early humans' offspring (后代) adapt to this new environment. Notably, the findings do not prove that Neanderthals' genes are responsible for the sleep habits of all early risers. Lots of different factors beyond genetics can contribute, including social and environmental influences. The study also only included DNA from a database called the UK Biobank—so the findings may not necessarily apply to all modern 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 humans. Next, the research team hopes to study other genetic databases to see if the same link holds true for people of other ancestries. If the findings do apply more broadly, they may one day be useful for improving sleep in the modern world, where circadian rhythms are disturbed by night shifts and glowing smartphones. 【语篇解读】本文是一篇说明文。文章主要介绍了一项新的研究，该研究表明今天有些人之所以早起，可能是因为他们遗传了数万年前尼安德塔人的DNA。 专题限时评价 任务二 任务三 任务一 专题一　阅读理解 5.
