What do you think a seed scientist does? Do you think it is an interesting job?（看课文标题，你认为种子科学家是做什么的？这工作有趣吗？课本 p.16） 1b Read the text quickly. Who was the seed scientist? What did he do? （快速阅读课文，种子科学家是谁？他做了什么？课本 p.16） 课文标题：The Inspiring Seed Scientist《鼓舞人心的种子科学家》 【知识点】 快速阅读策略（1b）：只找两个问题的答案——人物（who）与主要事迹（what），不逐词阅读。 读前预测（1a）：seed scientist = 科学家 + seed（种子），可猜到工作与收集、研究植物种子有关。 【提示框】 1b 只需在文中定位两个人名/数字信息：Zhong Yang（钟扬）与 40 million seeds（4000 万颗种子），先略读锁定段落。 1b 参考答案：The seed scientist was Zhong Yang, a biology professor at Fudan University. He spent his whole life researching plants and collected over 40 million seeds for China's seed banks. 1b 阅读文本：种子科学家钟扬的科考足迹 （二）1c 段落主题匹配 【过渡语】快速阅读找到主人公后，再看文章的段落结构。 Read again and match each paragraph with its topic.（再读课文，将段落与主题匹配。课本 p.17） Paragraph 1　　A. Training local students to do important work Paragraph 2　　B. Introduction to Zhong Yang and seed banks Paragraph 3　　C. What he left behind Paragraph 4　　D. Becoming interested in seeds Paragraph 5　　E. Starting to work and collect seeds in Xizang 1c 参考答案：Paragraph 1—B　Paragraph 2—D　Paragraph 3—E　Paragraph 4—A　Paragraph 5—C 💡 解题思路：抓每段首末句关键词：Para 1 讲车祸与种子库→B；Para 2 少年与大学→D；Para 3 西藏采集→E；Para 4 培训学生→A；Para 5 精神传承→C。 （三）1d 时间轴填空：用自己的话讲钟扬的故事 Fill in the blanks with the information from the text. Then put the events into the timeline and tell the story of Zhong Yang in your own words.（根据课文补全句子，再把事件排入时间轴，用自己的话讲述钟扬的故事。课本 p.17） A. Zhong Yang was born.　B. He ________ at the age of 15.　C. He began ________ to train local students. D. He died in ________.　E. He studied ________ and later ________.　F. He travelled around Xizang to ________.　G. Zhong Yang ________ plants. 1d 填空参考答案：B. entered university　C. a programme　D. 2017　E. radio engineering / became interested in plants　F. collect seeds himself　G. loved 时间轴事件顺序：A(1964 出生) → B(15 岁上大学) → E(学无线电工程，后对植物产生兴趣) → F(2001 年起赴西藏采集种子) → C(启动培训当地学生的项目) → D(2017 车祸去世) 复述示例：Zhong Yang was born in 1964. He entered university at just 15, first studying radio engineering but later becoming interested in plants. From 2001 he travelled across Xizang to collect seeds, braving cold weather and great heights. He also began a programme to train local students. Together they collected over 40 million seeds. He died in 2017, but his love for research lives on. 💡 解题思路：填空先定词性（15 岁做的事→entered university；began 后接名词短语 a programme），时间轴按年份排序后串词复述。 （四）细读课文：逐段获取细节信息 【过渡语】把握了整体结构，再逐段深挖细节。 细读第一段，回答： 1. What happened on 25 September 2017, and how did the scientific world react? 2. Why are seed banks important according to the passage? 细读第二至四段，补全信息图表：出生年份 / 上大学年龄 / 后来的兴趣与事业重心 / 成为教授的大学 / 开始西藏之旅的年份 / 在西藏面临的挑战 / 启动的项目 / 科学成就 【提示框】 细节题先看题干关键词再回文定位：2017→Para 1；seed banks 的作用→Para 1 后半；图表类题目按 Category 一栏一栏回原文找数字与名词。 问答参考答案：1. On 25 September 2017, Chinese professor Zhong Yang died in a car accident. The scientific world was shaken by the news.　2. Because seed banks protect all kinds of plant seeds, including those needed for food, and make sure that important plants do not disappear from the world forever. 图表参考答案：1964；15 岁；plants（seeds）；Fudan University；2001；cold weather, great heights, falling sick；to find and train local students in field research；collected over 40 million seeds from around 1,000 plants （五）1e 用上下文猜词义：brave 与 lives on 【过渡语】课文里有两个“熟词僻义”的表达，我们借助上下文来理解。 Explain the meanings of these sentences in your own words. Pay attention to the underlined words. （用自己的话解释句子含义，注意画线词。课本 p.17） 1. It was very difficult for him to brave the cold weather and great heights. 2. His love for his job and research lives on in his students. 策略提示（课本 Using context）：利用句子上下文猜测并学习难词与短语的意义。 【知识点】 brave 作动词（课本 p.16）：brave the cold weather and great heights = 勇敢面对严寒与高海拔。brave 既可作形容词“勇敢的”，也可作动词“勇敢面对”。 live on（课本 p.16）：His love lives on in his students. 指精神、爱、影响等“在……身上延续”，主语通常是非物质的东西。 上下文线索：前句说他 sometimes fell sick 但 always continued，可推知 brave = face... without giving up。 【提示框】 释义两步：① 用自己的话改写句子大意；② 从上下文找出画线词的判断依据（前后的关键词 fall sick / continue）。 💡 解题思路：第 1 句：面对严寒和高海拔还坚持采集种子 → brave 是“勇敢面对”；第 2 句：人已去世但学生仍在继续 → lives on 是“精神延续”。 （六）1f 讨论：钟扬为什么令人敬佩 Discuss the questions.（讨论问题。课本 p.17） 1. Why did Zhong Yang want more people to do seed collection and research? 2. What made Zhong Yang admirable? What can we learn from him? 【知识点】 讨论支架（源自课文）：It is better to include more people when doing important work.（it 句型复现）；His love for his job and research lives on in his students.（live on 精神延续） 讨论参考要点： 1. 他深知重要事业需要团队：培训当地学生既扩大了采集范围，也培养了能接续事业的后备科学家，让种子与研究惠及几百年后的世界（课文原句：Zhong Yang knew it was better to include more people when doing important work.）。 2. 令人敬佩之处：面对严寒高海拔与疾病仍坚持工作（dedication）；无私培养学生（selflessness）；着眼长远（vision）；从小热爱科学（passion）。 我们可以学到：面对困难不放弃；与他人分享知识与技能；做有益于后代的事；追随好奇心与热爱。 （七）课文语言点精讲 1. be shaken by... 被……震惊：The scientific world was shaken by the news. 科学界被这一消息震惊。 2. spend one's whole life doing sth 毕生做某事：He had spent his whole life researching plants and seeds. 3. make sure that... 确保……：They make sure that important plants do not disappear from the world forever. 4. show a deep love and curiosity for... 对……表现出深深的热爱与好奇：When he was young, he showed a deep love and curiosity for the things he studied. 5. enter university at the early age of... 在……岁的低龄就上大学：He was an excellent student, entering university at the early age of 15. 6. become the focus of one's life 成为某人一生的重心：The research and study of plants became the focus of his life. 7. brave v. 勇敢面对：It was very difficult for him to brave the cold weather and great heights. 8. continue with sth 继续（中断后的）某事：He sometimes fell sick, but he always continued with his work. 9. live on (in...) （精神）在……身上延续；continue on the road of... 继续走在……的道路上：His love lives on in his students. / My students will continue on the road of scientific exploration. 【知识点】 本课语言点两两对比：spend...doing（做某事花费时间）与 continue with（中断后继续）；live on（精神延续）与 continue on the road of（比喻“继续走在……道路上”）。 be shaken by 为被动语态：be + 过去分词 + by 施动者。 【提示框】 记短语抓“动词搭配”而非死记中文：spend...doing / make sure that / show...for / continue with / brave + 名词，抄录课文原句作为例句记忆最牢。 （八）2a 后缀 -ist / -er / -ian：学科与从业者 【过渡语】课文里的 biologist 和上节课的 historian 都带后缀，来系统梳理构词规律。 Circle the correct words to complete the sentences. Then write down more words ending with -ist, -er, and -ian. （圈出正确单词完成句子，再写出更多以 -ist、-er、-ian 结尾的词。课本 p.18） 1. When my sister grows up, she wants to become a science / scientist... 2. The history / historian wrote a book about the successful development of socialism in China. 3. My favourite school subject is chemistry / chemist. 4. Some biology / biologist students at the university are studying how life on earth began. 5. Teng Fei likes physics / physicist very much, and he wants to be a scientific researcher / research in the future. 后缀规律：-ist 加在学科/名词后表“从业者”（biologist 生物学家、scientist、artist、pianist、tourist）；-er 加在动词后表“做……的人”（teacher、worker、driver、singer、writer）；-ian 加在名词后表“精通……的人”（musician、mathematician、historian、librarian）。 【知识点】 2a 的考点是“学科名词 vs 从业者名词”的辨析（课本 p.18）： 学校科目用学科名词：My favourite subject is chemistry / physics / biology. 人作主语表职业用从业者名词：She wants to become a scientist. / a scientific researcher 学科名词还可作定语：biology students（生物学专业的学生） 【提示框】 第 3-5 题易错：subject 后接学科（chemistry/physics）；likes 后接学科（likes physics）；students 前是学科定语（biology students）——不要见动词就选“人”。 2a 参考答案：1. scientist　2. historian　3. chemistry　4. biology　5. physics；researcher （九）2b 词框填空：spread / wise / elder / calendar / radio Complete the sentences with the correct forms of the words in the box. （用方框中词的适当形式补全句子。课本 p.18） 词框：spread　wise　elder　calendar　radio 1. I heard about the latest discoveries about black holes on the ________. 2. Curiosity and ________ lead us to explore the secrets of the universe. 3. I would love to have lunch with you next week. Let me check my ________ to see if I am free. 4. You'd better wear a mask when you go out. The disease is ________, and the number of patients is going up. 5. Marie Curie's ________ daughter, Irène, was also very interested in science and won a Nobel Prize in Chemistry. 【提示框】 第 2 题注意：Curiosity and ________ 是两个并列主语，后面 lead 用原形——填 wise 的名词形式 wisdom（curiosity and wisdom 好奇心与智慧）。 2b 参考答案（课本 p.18）：1. radio　2. wisdom　3. calendar　4. spreading　5. elder （十）2c 语篇填空：飞行先驱阿梅莉亚·埃尔哈特 【过渡语】最后用一篇人物短文综合运用本课词汇，读一读飞行先驱的故事。 Complete the passage with the correct forms of the words in the box. Try to introduce Amelia Earhart in your own words.（用方框中词的适当形式补全短文，然后用自己的话介绍阿梅莉亚·埃尔哈特。课本 p.18） 词框：look up to　pioneer　courage　pilot　come true　encourage Amelia Earhart was always a brave child, full of ___________. Her parents supported and ____________ her to be herself. After taking her first flight in a plane, she knew that she wanted to become a ____________ more than anything else in the world. Earhart is best known for being a flight ___________ as the first woman to fly on her own across the Atlantic Ocean in 1932. Many people ______________ Earhart and find her an inspiring person because of her efforts to work hard and her ability to make her dreams ____________. 【知识点】 语篇中的词形变化（课本 p.18）：full of courage（名词）；supported and encouraged（并列过去式）；become a pilot（职业名词）；a flight pioneer（先驱）；people look up to Earhart（钦佩）；make her dreams come true（梦想成真，come true 不用被动）。 【提示框】 make her dreams ______ 用 come true 原形：make sth do 结构中不定式省略 to，梦想“实现”不用被动语态。 2c 参考答案（课本 p.18）：1. courage　2. encouraged　3. pilot　4. pioneer　5. look up to　6. come true 💡 解题思路：复述支架：Amelia Earhart was a brave child full of courage. She became a pilot and was the first woman to fly across the Atlantic alone. Many people look up to her because she made her dreams come true. 2c 语篇人物：飞行先驱阿梅莉亚·埃尔哈特 易错提醒 1b 只需在文中定位两个人名/数字信息：Zhong Yang（钟扬）与 40 million seeds（4000 万颗种子），先略读锁定段落。 细节题先看题干关键词再回文定位：2017→Para 1；seed banks 的作用→Para 1 后半；图表类题目按 Category 一栏一栏回原文找数字与名词。 释义两步：① 用自己的话改写句子大意；② 从上下文找出画线词的判断依据（前后的关键词 fall sick / continue）。 记短语抓“动词搭配”而非死记中文：spend...doing / make sure that / show...for / continue with / brave + 名词，抄录课文原句作为例句记忆最牢。 第 3-5 题易错：subject 后接学科（chemistry/physics）；likes 后接学科（likes physics）；students 前是学科定语（biology students）——不要见动词就选“人”。 第 2 题注意：Curiosity and ________ 是两个并列主语，后面 lead 用原形——填 wise 的名词形式 wisdom（curiosity and wisdom 好奇心与智慧）。 make her dreams ______ 用 come true 原形：make sth do 结构中不定式省略 to，梦想“实现”不用被动语态。 答题技巧 圈词题先看句法位置：become a ___ 表职业→选从业者；subject is ___ / likes ___ 表学科→选学科名词；___ students 作定语→选学科名词。 词框填空四步：① 判断空格词性（on the ___→名词；is ___→现在分词；Curie's ___ daughter→形容词）；② 选词；③ 变形（spreading）；④ 回读检验语义与搭配。 语言点归纳 课堂总结 本课时围绕“什么让人令人敬佩”主题（课本 p.16-18）： 1. 掌握 12 个核心词汇：scientific, biologist, whole, bank, forever, radio, leave behind, collection, live on, exploration, universe, socialism 2. 读懂人物传记类文本，完成段落匹配、时间轴填空与信息图表，学会用上下文猜测熟词僻义 3. 掌握 9 条课文语言点（be shaken by / spend one's whole life doing / make sure that 等）与 -ist/-er/-ian 构词规律，完成 2a/2b/2c 词汇运用任务 随堂笔记 AI生成 AIGC标识: 93acdc12-01d1-4fc3-b122-294ace95d34d 第 页 学科网（北京）股份有限公司 $
