He believed that science and technology could (tackle) even the most difficult challenges in agriculture and help (boost) crop production on a large scale. Through years of hard work, Yuan successfully developed high-(yield) hybrid rice varieties that could produce 20% more grain than traditional varieties, and (convince) farmers to adopt new planting methods. His achievements helped China (overcome) severe food crises and (expand) its agricultural capacity, enabling the nation to feed nearly one-fifth of the world's population. Today, Yuan's legacy continues to (generate) new breakthroughs in agricultural research. His vision for "seawater rice" aims to (attain) food security in areas with salty soil, proving that dedication and scientific innovation can truly change the world. He once said, "I have a dream that one day rice plants will grow as tall as sorghum." That dream is now becoming a reality. 【中文译文】 袁隆平被誉为"杂交水稻之父"，他毕生（devote）致力于解决困扰数百万中国人的粮食（shortage）短缺问题。他坚信科技能够（tackle）解决农业中最棘手的挑战，并帮助大规模（boost）提高粮食产量。 经过多年的艰苦努力，袁隆平成功培育出高（yield）产量的杂交水稻品种，将粮食增产20%以上，并（convince）说服农民采用新的种植方法。他的成就帮助中国（overcome）克服了严重的粮食危机，并（expand）扩大了农业产能，使国家得以养活世界近五分之一的人口。 如今，袁隆平的遗产继续（generate）催生农业研究的新突破。他的"海水稻"愿景旨在在盐碱地上（attain）实现粮食安全，证明了奉献精神和科学创新确实能够改变世界。他曾说："我有一个梦想，有一天水稻能长到高粱那么高。"这个梦想正在变为现实。 💡 语境串联记忆线索：投身奉献→解决短缺→应对挑战→提高产量→高产→说服→克服困难→扩大规模→催生突破→实现目标 记忆链：devote →

n.（奉献/热爱）也是派生词考察重点。2021年新高考II卷考查more devoted；2022年北京卷和浙江卷分别考查devote...to和devote myself to。 【词根联想】 de-（完全）+ vote（发誓/许愿，拉丁语vovere"发誓"）→ 完全发誓要做→献身/致力于。联想：vote（投票）本义是"庄严宣誓后的选择"，devote即"宣誓全身心投入"。 【经典原句】 ① "However, he is more devoted to his 'role' than any real actor." （2021·新高考II卷·语法填空·be devoted to 致力于） ② "It is important for everyone to devote some time to health and fitness." （2022·北京卷·语法填空·devote...to 把…用于） 【搭配词块】 devote oneself to (doing) sth 致力于 / be devoted to 献身于；深爱 / devotion n. 奉献；热爱 / devote one's life to 把一生奉献给 2. shortage /ˈʃɔːtɪdʒ/ n. 不足；短缺；缺少 【核心考点】 shortage是资源与环境话题核心名词。shortage of...（…的短缺）为阅读高频搭配。short adj.（短缺/矮的/简短的）及其多条词义构成熟词生义考点。be short of = lack（缺少）是写作同义替换高频表达。常见：food/water/energy shortage（粮食/水/能源短缺）。 【词根联想】 short（短的/缺少的）+ -age（名词后缀，表状态/数量）→ 短缺的状态→短缺。联想：short除"短"外还表"缺少"（run short of），shortage即"缺少的状态"。postage（邮资→邮政费用）、storage（存储→存放的状态）同为-age后缀名词。 【经典原句】 ① "The severe shortage of clean drinking water in some African regions has become a major concern for international aid organizations." （经典原句·shortage of 短缺） 【搭配词块】 shortage of... …的短缺 / food/water shortage 粮食/水短缺 / be short of 缺少 / run short 快用完了 3. tackle /ˈtækl/ vt. 处理；解决；与…交涉 【核心考点】 tackle是问题解决类核心动词。tackle a problem/challenge/issue（处理问题/挑战）为阅读、写作高频表达，可替代solve/deal with/handle。2024年多地模拟题的七选五和完形填空中反复出现。注意：tackle作名词意为"（足球等运动中的）擒抱/阻截"和"用具/器械"，构成熟词生义考点。 【词根联想】 源自古英语tacel（工具/器具）→ 中古英语"船上索具"→ 引申为"着手处理（问题）"→ 解决问题。联想：从"拿起工具"到"处理问题"，工具的"抓握"概念延伸为"应对挑战"。 【熟词生义】 熟词生义：n. ①（足球等中的）擒抱摔倒；阻截 ② 用具；钓具。例：He bought some new fishing tackle before the weekend trip.（他在周末出游前买了一些新渔具。）本义"工具/器械"，后引申为"处理问题→解决"。 【经典原句】 ① "To tackle this growing problem, the government has launched a series of policies aimed at reducing food waste at every stage." （经典原句·tackle 处理/解决） 【搭配词块】 tackle a problem/challenge 处理问题 / tackle the issue 解决这个问题 / tackle sb about sth 就某事与某人交涉 / fishing tackle 钓鱼用具 4. boost /buːst/ vt. & n. 促进；提高；增加 【核心考点】 boost是写作中表达"促进/提高"的高频升级词，可替代improve/increase/raise。boost the economy（促进经济）、boost production（提高产量）、boost one's confidence（增强信心）为常见搭配。2023年新高考I卷七选五原文it's a great way to boost self-confidence。作名词时give a boost to...（给…以推动）。 【词根联想】 源于19世纪美国英语，词源不确定，可能与boast（吹嘘/夸耀）同源→"用力向上推"→促进/提高。联想：boost像boast（夸耀）——"夸耀就是把自己的形象推高"。 【经典原句】 ① "In fact, don't wait until you've made a mistake to try this — it's a great way to boost self-confidence at any time." （2023·新高考I卷·七选五·boost self-confidence 增强自信） 【搭配词块】 boost the economy 促进经济 / boost production 提高产量 / boost one's confidence 增强信心 / give a boost to 推动；促进 5. yield /jiːld/ n. 产量；产出 vt. 出产；屈服；让步 【核心考点】 yield是农业与科学话题核心词。n. 产量（高频阅读词）；v. 出产/产生（yield results/results）。最关键考点是熟词生义yield to（屈服于/让步于），完形填空和阅读理解中常见。high-yield（高产的）为农业科技话题核心形容词。注意区分yield（产出/屈服）和field（田地）。 【词根联想】 源自古英语gieldan（支付/偿还）→ 中古英语"出产/产出"→ 引申为"放弃/屈服"（把东西"交出去"）。联想：yield的"出产→交出→屈服"链条体现了词义的引申逻辑。 【熟词生义】 熟词生义：vi. 屈服；让步。例：After hours of negotiation, the company finally yielded to the workers' demands for better working conditions.（经过数小时谈判，公司最终屈服于工人对更好工作条件的要求。）本义"出产"→"交出/放弃"→"屈服"。 【经典原句】 ① "The new rice variety developed by the research team can yield up to 15 tons per hectare, nearly doubling the previous record." （经典原句·yield 出产） 【搭配词块】 yield results 产出结果 / yield to 屈服于；让步于 / high-yield adj. 高产的 / crop yield 作物产量 6. convince /kənˈvɪns/ vt. 使相信；说服 【核心考点】 convince是论证与说服类核心动词。convince sb of sth（使某人相信某事）、convince sb to do（说服某人做某事）、be convinced that...（确信…）为语法填空和写作高频结构。convincing adj.（有说服力的）和convinced adj.（确信的）的人-物区别为必考要点。2022年新高考I卷满分作文使用I am convinced that...；2023年北京卷考查convincingly。 【词根联想】 con-（完全）+ vince（征服/战胜，拉丁语vincere"征服"）→ 完全征服（对方的想法）→ 使信服。联想：同词根victory（胜利→征服的结果）、invincible（不可战胜的→in-不+vinc-征服+-ible可…的）。 【经典原句】 ① "As you are a cultural envoy, I am convinced that your attendance will surely add color to our program." （2022·新高考I卷·满分作文·be convinced that 确信） 【搭配词块】 convince sb of sth 使某人相信某事 / convince sb to do 说服某人做 / be convinced that... 确信… / convincing adj. 有说服力的 7. overcome /ˌəʊvəˈkʌm/ vt. 克服；战胜；解决 【核心考点】 overcome是励志类话题核心动词。overcome difficulties/fear/challenges（克服困难/恐惧/挑战）为写作常用表达。注意不规则变化：overcome — overcame — overcome。overcome常与obstacle（障碍）、barrier（阻碍）、shyness（害羞）等搭配。谚语Overcome evil with good.（以善胜恶）。 【词根联想】 over-（越过/在上面）+ come（来）→ 从上方越过来→ 克服/战胜。联想：over前缀表"越过"，overcome字面意思"从困难上面跨过去"。同类构词：overlook（俯视→忽略）、overwhelm（压倒→使不知所措）。 【经典原句】 ① "With strong determination and support from her family, she managed to overcome her fear of public speaking and successfully delivered a speech to over 500 people." （经典原句·overcome fear 克服恐惧） 【搭配词块】 overcome difficulties/fear 克服困难/恐惧 / overcome obstacles 克服障碍 / overcome — overcame — overcome / be overcome with/by 被…所压倒 8. expand /ɪkˈspænd/ vt. & vi. 扩大；扩展；膨胀 【核心考点】 expand是发展与增长类核心动词。expand one's knowledge/horizons（扩展知识/视野）为写作和阅读高频搭配。expand→expansion n.（扩张）→expansive adj.（广阔的/扩张性的）构成派生考点链。注意区分expand（扩大/膨胀）和extend（延伸/延长）。expand侧重体积/规模增大，extend侧重时间/空间延长。 【词根联想】 ex-（向外/出）+ pand（展开/伸展，拉丁语pandere"展开"）→ 向外展开→扩大/扩展。联想：同词根panorama（全景→全展开的视野），expanse（广阔区域→完全展开的空间）。 【经典原句】 ① "By reading widely and traveling to different countries, students can greatly expand their horizons and gain a deeper understanding of the world." （经典原句·expand horizons 扩展视野） 【搭配词块】 expand one's horizons 扩展视野 / expand the business 扩大业务 / expand into 扩展到 / expansion n. 扩张；膨胀 9. generate /ˈdʒenəreɪt/ vt. 产生；引起；生成 【核心考点】 generate是成果类核心动词。generate interest（引起兴趣）、generate income（产生收入）、generate electricity（发电）为阅读和写作核心搭配。generate→generation n.（产生/一代人）→generator n.（发电机/发生器）构成派生链。注意generation"产生"和"一代人"两个含义的语境区分。 【词根联想】 gen（产生/出生，拉丁语genus"种类/出生"）+ -er（反复）+ -ate（动词后缀）→ 反复产生→产生/生成。联想：同词根generate（产生）、generation（一代人→出生的一批）、gene（基因→决定出生特征的东西）、genius（天才→天生才能）。 【经典原句】 ① "The project is expected to generate more than 5,000 new jobs and bring about one billion yuan in revenue to the local economy." （经典原句·generate jobs 创造就业） 【搭配词块】 generate interest/income 产生兴趣/收入 / generate electricity 发电 / generation n. 产生；一代人 / generator n. 发电机 10. attain /əˈteɪn/ vt. 达到；获得；实现 【核心考点】 attain是目标实现类高级动词，写作中可替代achieve/get/reach，提升表达档次。attain one's goal/dream/ambition（实现目标/梦想/抱负）为经典搭配。attainable adj.（可达到的）→attainment n.（达到/成就）为派生考点。近义辨析：attain（经过努力达到）vs obtain（通过请求/购买获得）vs

Many outstanding scientists have (devote) their entire lives to solving the food (shortage) problem that affects millions of people worldwide, and their groundbreaking work has repeatedly shown that scientific research can (tackle) even the most difficult challenges and significantly (boost) food production for entire nations. Yuan Longping, a Chinese agricultural scientist, is perhaps the most famous example. He spent decades developing high-(yield) hybrid rice varieties that could produce much more grain per hectare than traditional varieties. His success helped (convince) farmers and governments alike that modern agricultural science could help (overcome) the threat of hunger. Thanks to his work, China was able to greatly (expand) its rice production and ensure food security for its huge population. Today, Yuan's legacy continues to inspire researchers around the world. New technologies and innovative farming methods continue to (generate) exciting breakthroughs, from drought-resistant crops to vertical farming systems that can grow food in urban environments. While challenges remain, the goal of helping every country (attain) food self-sufficiency is becoming more achievable than ever. As Yuan himself once said, "Chance favors the prepared mind," and the scientific community remains committed to preparing for a better-fed world. 1. What is the main purpose of the first paragraph? A. To introduce the idea that scientists have devoted themselves to tackling the worldwide food shortage and boosting production. B. To argue that food production is no longer a problem that modern society needs to worry about. C. To describe the daily eating habits of people living in countries with serious food shortages. D. To explain why traditional farming methods are always better than modern scientific approaches. 2. According to the second paragraph, what did Yuan Longping achieve? A. He traveled to every country in the world to give lectures on agricultural science. B. He decided to give up scientific research and become a traditional farmer in his hometown. C. He developed hybrid rice that greatly increased grain output and convinced others to accept modern farming science. D. He proved that expanding food production is impossible without using chemical fertilizers extensively. 3. What can be learned from the third paragraph about modern agricultural research? A. All countries have already attained complete food self-sufficiency thanks to modern technology. B. Vertical farming has completely replaced traditional agriculture in most urban areas around the world. C. New technologies continue to generate breakthroughs, from drought-resistant crops to urban vertical farming. D. Researchers have stopped working on food-related problems because Yuan Longping already solved them all. 4. What does the quote "Chance favors the prepared mind" suggest in the context of this passage? A. Only people who are born into wealthy families can make important scientific discoveries. B. Preparation and hard work are unnecessary because success depends entirely on random luck. C. Success in agricultural science comes purely from waiting for good opportunities to arrive naturally. D. Scientists must devote themselves to preparation and hard work so they can seize opportunities when they arise. 📖 本语篇覆盖的目标词汇：devote, shortage, tackle, boost, yield, convince, overcome, expand, generate, attain Part 8 复现知识点 — 英译汉 请根据英文写出对应汉语释义： 乐思英语 ·高考高频知识点 1 学科网（北京）股份有限公司 1. devote — __________ 2. shortage — __________ 3. tackle — __________ 4. boost — __________ 5. yield — __________ 6. convince — __________ 7. overcome — __________ 8. expand — __________ 9. generate — __________ 10. attain — __________ 11. devotion — __________ 12. be short of — __________ 13. yield to — __________ 14. convinced — __________ 15. expansion — __________ 16. generation — __________ 17. attainable — __________ 18. convincing — __________ 19. high-yield — __________ 20. devote...to... — __________ Part 9 写作运用 — 词汇升级 同义转换：用本专题词汇替换下面句中的普通词，提升写作表达： 1.

n.（奉献/热爱）也是派生词考察重点。2021年新高考II卷考查more devoted；2022年北京卷和浙江卷分别考查devote...to和devote myself to。 【词根联想】 de-（完全）+ vote（发誓/许愿，拉丁语vovere"发誓"）→ 完全发誓要做→献身/致力于。联想：vote（投票）本义是"庄严宣誓后的选择"，devote即"宣誓全身心投入"。 【经典原句】 ① "However, he is more devoted to his 'role' than any real actor." （2021·新高考II卷·语法填空·be devoted to 致力于） ② "It is important for everyone to devote some time to health and fitness." （2022·北京卷·语法填空·devote...to 把…用于） 【搭配词块】 devote oneself to (doing) sth 致力于 / be devoted to 献身于；深爱 / devotion n. 奉献；热爱 / devote one's life to 把一生奉献给 2. shortage /ˈʃɔːtɪdʒ/ n. 不足；短缺；缺少 【核心考点】 shortage是资源与环境话题核心名词。shortage of...（…的短缺）为阅读高频搭配。short adj.（短缺/矮的/简短的）及其多条词义构成熟词生义考点。be short of = lack（缺少）是写作同义替换高频表达。常见：food/water/energy shortage（粮食/水/能源短缺）。 【词根联想】 short（短的/缺少的）+ -age（名词后缀，表状态/数量）→ 短缺的状态→短缺。联想：short除"短"外还表"缺少"（run short of），shortage即"缺少的状态"。postage（邮资→邮政费用）、storage（存储→存放的状态）同为-age后缀名词。 【经典原句】 ① "The severe shortage of clean drinking water in some African regions has become a major concern for international aid organizations." （经典原句·shortage of 短缺） 【搭配词块】 shortage of... …的短缺 / food/water shortage 粮食/水短缺 / be short of 缺少 / run short 快用完了 3. tackle /ˈtækl/ vt. 处理；解决；与…交涉 【核心考点】 tackle是问题解决类核心动词。tackle a problem/challenge/issue（处理问题/挑战）为阅读、写作高频表达，可替代solve/deal with/handle。2024年多地模拟题的七选五和完形填空中反复出现。注意：tackle作名词意为"（足球等运动中的）擒抱/阻截"和"用具/器械"，构成熟词生义考点。 【词根联想】 源自古英语tacel（工具/器具）→ 中古英语"船上索具"→ 引申为"着手处理（问题）"→ 解决问题。联想：从"拿起工具"到"处理问题"，工具的"抓握"概念延伸为"应对挑战"。 【熟词生义】 熟词生义：n. ①（足球等中的）擒抱摔倒；阻截 ② 用具；钓具。例：He bought some new fishing tackle before the weekend trip.（他在周末出游前买了一些新渔具。）本义"工具/器械"，后引申为"处理问题→解决"。 【经典原句】 ① "To tackle this growing problem, the government has launched a series of policies aimed at reducing food waste at every stage." （经典原句·tackle 处理/解决） 【搭配词块】 tackle a problem/challenge 处理问题 / tackle the issue 解决这个问题 / tackle sb about sth 就某事与某人交涉 / fishing tackle 钓鱼用具 4. boost /buːst/ vt. & n. 促进；提高；增加 【核心考点】 boost是写作中表达"促进/提高"的高频升级词，可替代improve/increase/raise。boost the economy（促进经济）、boost production（提高产量）、boost one's confidence（增强信心）为常见搭配。2023年新高考I卷七选五原文it's a great way to boost self-confidence。作名词时give a boost to...（给…以推动）。 【词根联想】 源于19世纪美国英语，词源不确定，可能与boast（吹嘘/夸耀）同源→"用力向上推"→促进/提高。联想：boost像boast（夸耀）——"夸耀就是把自己的形象推高"。 【经典原句】 ① "In fact, don't wait until you've made a mistake to try this — it's a great way to boost self-confidence at any time." （2023·新高考I卷·七选五·boost self-confidence 增强自信） 【搭配词块】 boost the economy 促进经济 / boost production 提高产量 / boost one's confidence 增强信心 / give a boost to 推动；促进 5. yield /jiːld/ n. 产量；产出 vt. 出产；屈服；让步 【核心考点】 yield是农业与科学话题核心词。n. 产量（高频阅读词）；v. 出产/产生（yield results/results）。最关键考点是熟词生义yield to（屈服于/让步于），完形填空和阅读理解中常见。high-yield（高产的）为农业科技话题核心形容词。注意区分yield（产出/屈服）和field（田地）。 【词根联想】 源自古英语gieldan（支付/偿还）→ 中古英语"出产/产出"→ 引申为"放弃/屈服"（把东西"交出去"）。联想：yield的"出产→交出→屈服"链条体现了词义的引申逻辑。 【熟词生义】 熟词生义：vi. 屈服；让步。例：After hours of negotiation, the company finally yielded to the workers' demands for better working conditions.（经过数小时谈判，公司最终屈服于工人对更好工作条件的要求。）本义"出产"→"交出/放弃"→"屈服"。 【经典原句】 ① "The new rice variety developed by the research team can yield up to 15 tons per hectare, nearly doubling the previous record." （经典原句·yield 出产） 【搭配词块】 yield results 产出结果 / yield to 屈服于；让步于 / high-yield adj. 高产的 / crop yield 作物产量 6. convince /kənˈvɪns/ vt. 使相信；说服 【核心考点】 convince是论证与说服类核心动词。convince sb of sth（使某人相信某事）、convince sb to do（说服某人做某事）、be convinced that...（确信…）为语法填空和写作高频结构。convincing adj.（有说服力的）和convinced adj.（确信的）的人-物区别为必考要点。2022年新高考I卷满分作文使用I am convinced that...；2023年北京卷考查convincingly。 【词根联想】 con-（完全）+ vince（征服/战胜，拉丁语vincere"征服"）→ 完全征服（对方的想法）→ 使信服。联想：同词根victory（胜利→征服的结果）、invincible（不可战胜的→in-不+vinc-征服+-ible可…的）。 【经典原句】 ① "As you are a cultural envoy, I am convinced that your attendance will surely add color to our program." （2022·新高考I卷·满分作文·be convinced that 确信） 【搭配词块】 convince sb of sth 使某人相信某事 / convince sb to do 说服某人做 / be convinced that... 确信… / convincing adj. 有说服力的 7. overcome /ˌəʊvəˈkʌm/ vt. 克服；战胜；解决 【核心考点】 overcome是励志类话题核心动词。overcome difficulties/fear/challenges（克服困难/恐惧/挑战）为写作常用表达。注意不规则变化：overcome — overcame — overcome。overcome常与obstacle（障碍）、barrier（阻碍）、shyness（害羞）等搭配。谚语Overcome evil with good.（以善胜恶）。 【词根联想】 over-（越过/在上面）+ come（来）→ 从上方越过来→ 克服/战胜。联想：over前缀表"越过"，overcome字面意思"从困难上面跨过去"。同类构词：overlook（俯视→忽略）、overwhelm（压倒→使不知所措）。 【经典原句】 ① "With strong determination and support from her family, she managed to overcome her fear of public speaking and successfully delivered a speech to over 500 people." （经典原句·overcome fear 克服恐惧） 【搭配词块】 overcome difficulties/fear 克服困难/恐惧 / overcome obstacles 克服障碍 / overcome — overcame — overcome / be overcome with/by 被…所压倒 8. expand /ɪkˈspænd/ vt. & vi. 扩大；扩展；膨胀 【核心考点】 expand是发展与增长类核心动词。expand one's knowledge/horizons（扩展知识/视野）为写作和阅读高频搭配。expand→expansion n.（扩张）→expansive adj.（广阔的/扩张性的）构成派生考点链。注意区分expand（扩大/膨胀）和extend（延伸/延长）。expand侧重体积/规模增大，extend侧重时间/空间延长。 【词根联想】 ex-（向外/出）+ pand（展开/伸展，拉丁语pandere"展开"）→ 向外展开→扩大/扩展。联想：同词根panorama（全景→全展开的视野），expanse（广阔区域→完全展开的空间）。 【经典原句】 ① "By reading widely and traveling to different countries, students can greatly expand their horizons and gain a deeper understanding of the world." （经典原句·expand horizons 扩展视野） 【搭配词块】 expand one's horizons 扩展视野 / expand the business 扩大业务 / expand into 扩展到 / expansion n. 扩张；膨胀 9. generate /ˈdʒenəreɪt/ vt. 产生；引起；生成 【核心考点】 generate是成果类核心动词。generate interest（引起兴趣）、generate income（产生收入）、generate electricity（发电）为阅读和写作核心搭配。generate→generation n.（产生/一代人）→generator n.（发电机/发生器）构成派生链。注意generation"产生"和"一代人"两个含义的语境区分。 【词根联想】 gen（产生/出生，拉丁语genus"种类/出生"）+ -er（反复）+ -ate（动词后缀）→ 反复产生→产生/生成。联想：同词根generate（产生）、generation（一代人→出生的一批）、gene（基因→决定出生特征的东西）、genius（天才→天生才能）。 【经典原句】 ① "The project is expected to generate more than 5,000 new jobs and bring about one billion yuan in revenue to the local economy." （经典原句·generate jobs 创造就业） 【搭配词块】 generate interest/income 产生兴趣/收入 / generate electricity 发电 / generation n. 产生；一代人 / generator n. 发电机 10. attain /əˈteɪn/ vt. 达到；获得；实现 【核心考点】 attain是目标实现类高级动词，写作中可替代achieve/get/reach，提升表达档次。attain one's goal/dream/ambition（实现目标/梦想/抱负）为经典搭配。attainable adj.（可达到的）→attainment n.（达到/成就）为派生考点。近义辨析：attain（经过努力达到）vs obtain（通过请求/购买获得）vs acquire（逐步习得）。 【词根联想】 at-（朝/向，ad-的变体）+ tain（触摸/抓住，拉丁语tangere"触摸"→tenere"抓住"）→ 朝目标伸出手去→达到/获得。联想：同词根contain（容纳→一起抓住）、maintain（维持→用手抓住）、obtain（获得→朝…抓去）。 【经典原句】 ① "Through years of dedicated practice and

challenge of feeding a growing population has been one of humanity's greatest and most urgent concerns. Many outstanding scientists have (devote) their entire lives to solving the food (shortage) problem that affects millions of people worldwide, and their groundbreaking work has repeatedly shown that scientific research can (tackle) even the most difficult challenges and significantly (boost) food production for entire nations. Yuan Longping, a Chinese agricultural scientist, is perhaps the most famous example. He spent decades developing high-(yield) hybrid rice varieties that could produce much more grain per hectare than traditional varieties. His success helped (convince) farmers and governments alike that modern agricultural science could help (overcome) the threat of hunger. Thanks to his work, China was able to greatly (expand) its rice production and ensure food security for its huge population. Today, Yuan's legacy continues to inspire researchers around the world. New technologies and innovative farming methods continue to (generate) exciting breakthroughs, from drought-resistant crops to vertical farming systems that can grow food in urban environments. While challenges remain, the goal of helping every country (attain) food self-sufficiency is becoming more achievable than ever. As Yuan himself once said, "Chance favors the prepared mind," and the scientific community remains committed to preparing for a better-fed world. 1. What is the main purpose of the first paragraph? A. To introduce the idea that scientists have devoted themselves to tackling the worldwide food shortage and boosting production. B. To argue that food production is no longer a problem that modern society needs to worry about. C. To describe the daily eating habits of people living in countries with serious food shortages. D. To explain why traditional farming methods are always better than modern scientific approaches. 2. According to the second paragraph, what did Yuan Longping achieve? A. He traveled to every country in the world to give lectures on agricultural science. B. He decided to give up scientific research and become a traditional farmer in his hometown. C. He developed hybrid rice that greatly increased grain output and convinced others to accept modern farming science. D. He proved that expanding food production is impossible without using chemical fertilizers extensively. 3. What can be learned from the third paragraph about modern agricultural research? A. All countries have already attained complete food self-sufficiency thanks to modern technology. B. Vertical farming has completely replaced traditional agriculture in most urban areas around the world. C. New technologies continue to generate breakthroughs, from drought-resistant crops to urban vertical farming. D. Researchers have stopped working on food-related problems because Yuan Longping already solved them all. 4. What does the quote "Chance favors the prepared mind" suggest in the context of this passage? A. Only people who are born into wealthy families can make important scientific discoveries. B. Preparation and hard work are unnecessary because success depends entirely on random luck. C. Success in agricultural science comes purely from waiting for good opportunities to arrive naturally. D. Scientists must devote themselves to preparation and hard work so they can seize opportunities when they arise. 参考答案与高考标准解析 答案：1.A 2.C 3.C 4.D 第1题（主旨大意题·高考核心）：首段以devote、shortage、tackle、boost四个目标词构成"科学家献身→粮食短缺→应对挑战→提高产量"的递进逻辑。开篇"the challenge of feeding a growing population"确立问题框架，"Many scientists have devoted their lives"引出应对力量，"scientific research can tackle even the most difficult challenges and significantly boost food production"收束于解决方案与成果。选项A完整囊括了这四个层次：科学家献身+全球粮食短缺+应对挑战+提高产量。B项将全文核心问题轻描淡写为"不再需要担忧"；C项"描写日常饮食习惯"偷换概念；D项"传统方法永远更好"与devoted to solving through science的科学立场直接对立，属于正反颠倒型干扰。 第2题（细节理解题·高频题型）：第二段密集使用yield、convince、overcome、expand四个目标词串联袁隆平的科研贡献链："developing high-yield hybrid rice"→产量成果（yield），"helped convince farmers and governments"→推广转化（convince），"help overcome the threat of hunger"→克服危机（overcome），"greatly expand its rice production"→扩大产能（expand）。A项"走遍世界各国"将convince的具体内容过度夸张为全球旅行；选项B项"放弃科研"与decades of work的持久耕耘正反颠倒；C准确把握了"培育高产品种"和"说服他人接受现代科学"两大核心贡献。D项"没有化肥就不可能"在expand和overcome的积极语境中属于无中生有的消极推断。 第3题（细节理解题·中频题型）：第三段以generate和attain两个目标词引领现代研究图景。"New technologies continue to generate exciting breakthroughs"点明科研活力的持续性，"from drought-resistant crops to vertical farming"列举两类突破方向，"helping every country attain food self-sufficiency"勾勒终极目标。选项C准确概括了"新技术→催生突破→抗旱作物与城市垂直农业"的信息链。A项"所有国家已实现"与"While challenges remain"及attain的"尚在追求"语义矛盾；B项"完全取代传统农业"将innovative methods的补充性过度解读为替代性；D项"已停止工作"与"remains committed to preparing"的持续承诺正反颠倒，属于典型的绝对否定型干扰。 第4题（推理判断题·高考压轴）："Chance favors the prepared mind"（机遇青睐有准备的头脑）作为袁隆平的核心名言出现在文章收束位置，与首段的devote形成首尾呼应。该名言强调两层含义：①"prepared mind"对应devote oneself to preparation（致力于准备）的奉献精神；②"favors"暗示机遇是准备的自然结果，而非被动等待。选项D将这两层含义融入"致力于准备和努力→抓住机遇"的逻辑链条中，同时与全文devote→tackle→attain的递进主题形成闭环。A项"只有富家子弟"用出身替代努力，严重曲解名言内涵；B项"努力毫无必要"与prepared（有准备的）的核心要义完全对立；C项"纯靠等待"将"有准备的头脑"偷换为"什么都不做的等待"，是典型的望文生义型干扰。 📖 本语篇覆盖的目标词汇：devote, shortage, tackle, boost, yield, convince, overcome, expand, generate, attain Part 8 复现知识点 — 英译汉 请根据英文写出对应汉语释义： 乐思英语 ·高考高频知识点 1 学科网（北京）股份有限公司 1. devote — __________ 2. shortage — __________ 3. tackle — __________ 4. boost — __________ 5. yield — __________ 6. convince — __________ 7. overcome — __________ 8. expand — __________ 9. generate — __________ 10. attain — __________ 11. devotion — __________ 12. be short of — __________ 13. yield to — __________ 14. convinced — __________ 15. expansion — __________ 16. generation — __________ 17. attainable — __________ 18. convincing — __________ 19. high-yield — __________ 20. devote...to... — __________ 【参考答案】 1. 献身；致力于 2. 不足；短缺 3. 处理；解决 4. 促进；提高 5. 产量；出产；屈服 6. 使相信；说服 7. 克服；战胜 8. 扩大；扩展 9. 产生；引起 10. 达到；获得 11. 奉献；热爱（名词） 12. 缺少（短语） 13. 屈服于（熟词生义） 14. 确信的（形容词） 15. 扩张（名词） 16. 产生；一代人（名词） 17. 可达到的（形容词） 18. 有说服力的（形容词） 19. 高产的（形容词） 20. 把…奉献给（短语） Part 9 写作运用 — 词汇升级 同义转换：用本专题词汇替换下面句中的普通词，提升写作表达： 1.
