He worked in a quiet province with a broad knowledge of medicine. He did not intend to discover a miracle, but he noticed that some extract of a common herb seemed to kill the germs. He began to refer to his old notes and planned a careful experiment. After many trials, the results were still limited, and the cost was too high for a poor household. He needed a bigger container and could not postpone the tests any longer. With sufficient data from the lab, the project began to speed up, and finally his hard work began to pay off. Every error taught him something new, and through trial and error he gained real wisdom. He wrote down every small change in the lab and never gave up, because he believed that even the smallest step could lead to a great result one day. The new medicine proved beneficial to thousands of patients. Scientists learned how to conduct the tests and could illustrate the results clearly. The famous discovery of penicillin came from a piece of mould that killed the bacteria around it. The team was surrounded by unexpected helpers, and they realized that nature often gives us hints. The results clearly indicate that such a lucky accident was not really by accident at all. It needed an intelligent mind to see the value, and favour smiled on those who worked hard. Even a politician could see the importance, because lightning of genius strikes like real electricity. According to a new theory, a sudden thunderstorm of ideas can hit the mind, and the ribbon of discovery is tied with metal and hard work. You can charge a battery with electric energy, and the sudden bang of an idea can arrive with a bang. Great discoveries often come to those who keep their eyes open and their minds ready at any moment. Such great discoveries made the scientist a standout figure in the atomic age, though he feared that a bomb might bring evil to the world. Science can involve great risks, and every scientific advance deserves credit. There is also a moral question: how should we apply this new power? We must not negate the value of life, and we should protect our intellectual freedom. The mystery of nature should never let sb. down; only ignorance does. as to the future, we should never take it for granted that science is always safe. True freedom comes with authority and respect. The law may permit some uses, but each person has a responsibility to think carefully. We should declare our beliefs openly, whatever our nationality is. New ideas are put forward every day, and the evolution of science continues. Many books are published each year, and the story of every great marriage between science and humanity is worth reading. Scientists remind us that curiosity and honesty are the best friends of progress, and they guide us toward a brighter future for all people. B. 语境串记单词（汉语译文） 1928 年，在一个欧洲小(republic)共和国里，一位科学家正在研究(malaria)疟疾，这是一种威胁数百万人(survival)生存的(deadly)致命疾病。他在一个安静的(province)省份工作，拥有(broad)广泛的医学知识。他并没有(intend)打算发现奇迹，但他注意到一种普通(herb)药草的(extract)提取物似乎能杀死病菌。他开始(refer to)查阅旧笔记，并计划进行一项仔细的(experiment)实验。经过多次(trial)试验，结果仍然(limited)有限，而且费用对贫穷的(household)家庭来说太高了。他需要更大的(container)容器，不能再(postpone)推迟试验了。有了实验室(sufficient)充足的(data)数据，项目开始(speed up)加速，最终他的努力开始(pay off)奏效。每一个(error)错误都教会他新的东西，(through trial and error)通过反复试验，他获得了真正的(wisdom)智慧。 新药被证明对数以千计的病人(beneficial)有益。科学家们学会了如何(conduct)进行测试，并能清楚地(illustrate)说明结果。著名的(penicillin)青霉素发现来自一块杀死了周围(bacteria)细菌的(mould)霉菌。团队被意想不到的帮手(surround)围绕，他们意识到大自然常常给我们提示。结果清楚地(indicate)表明，这样幸运的(accident)意外并非真的(by accident)偶然。它需要一个(intelligent)有才智的头脑看到其价值，(favour)幸运眷顾那些努力工作的人。甚至(politician)政治家也能看到其重要性，因为天才的(lightning)闪电像真正的(electricity)电一样击中人心。根据一种新(theory)理论，思想的(thunderstorm)雷暴会突然袭来，发现的(ribbon)丝带是由(metal)金属和辛勤工作系在一起的。你可以用(electric)电的能量给电池(charge)充电，一个想法的突然(bang)巨响可能(with a bang)引人注目地到来。 如此伟大的发现使这位科学家成为(atomic)原子时代的(standout)杰出人物，尽管他担心(bomb)炸弹会给世界带来(evil)罪恶。科学可能(involve)涉及巨大风险，每一项(scientific)科学进步都值得(credit)赞扬。还有一个(moral)道德问题：我们应该如何(apply)应用这种新力量？我们不能(negate)否定生命的价值，应该保护我们的(intellectual)智力自由。自然的(mystery)神秘不应(let sb. down)辜负我们；只有(ignorance)无知才会。(as to)至于未来，我们不应(take it for granted)理所当然地认为科学总是安全的。真正的(freedom)自由伴随着(authority)权威和尊重。法律可能(permit)允许某些用途，但每个人都有(responsibility)责任去仔细思考。无论我们的(nationality)国籍是什么，我们都应该公开(declare)表明自己的信念。每天都有新想法被(put forward)提出，科学的(evolution)进化仍在继续。每年有许多书被(publish)出版，科学与人性每一次伟大(marriage)结合的故事都值得一读。 第二部分：词形转变表 序号 原词 词形变化 1 deadly adj.致命的 dead (adj.) 死的；death (n.) 死亡 2 survive v.生存 survival (n.) 生存；survivor (n.) 幸存者 3 broad adj.广泛的 broadly (adv.) 广泛地；broaden (v.) 加宽 4 intend v.想要 intention (n.) 意图；intended (adj.) 打算中的 5 extract v.提取 extraction (n.) 提取；extracted (过去式) 6 experiment n.实验 experimental (adj.) 实验的；experimentation (n.) 实验 7 limit v.限制 limited (adj.) 有限的；limitation (n.) 限制 8 sufficient adj.足够的 sufficiently (adv.) 足够地；sufficiency (n.) 充足 9 wisdom n.智慧 wise (adj.) 明智的；wisely (adv.) 明智地 10 beneficial adj.有益的 benefit (n.) 益处；beneficially (adv.) 有益地 11 conduct v.实施 conduction (n.) 传导；conducted (过去式) 12 indicate v.表明 indication (n.) 迹象；indicator (n.) 指示器 13 intelligent adj.聪明的 intelligence (n.) 智力；intelligently (adv.) 聪明地 14 theory n.理论 theoretical (adj.) 理论的；theoretically (adv.) 理论上 15 electric adj.电的 electricity (n.) 电；electrical (adj.) 电气的 16 involve v.涉及 involved (adj.) 参与的；involvement (n.) 参与 17 apply v.应用 application (n.) 应用；applicable (adj.) 适用的 18 publish v.出版 publication (n.) 出版；published (过去式) 第三部分：梯度复现与多题型练习 题型1：英汉互译（30题） 乐思英语 ·语境串记单词 第 10 / 17 页 学科网（北京）股份有限公司 子题A：英译中（20个） 1. republic → __________ 2. deadly → __________ 3. survival → __________ 4. broad → __________ 5. intend → __________ 6. herb → __________ 7. experiment → __________ 8. trial → __________ 9. limited → __________ 10. sufficient → __________ 11. data → __________ 12. wisdom → __________ 13. beneficial → __________ 14. conduct → __________ 15. bacteria → __________ 16. indicate → __________ 17. accident → __________ 18. intelligent → __________ 19. theory → __________ 20. charge → __________ 子题B：中译英（10个） 1. 共和国 → __________ 2. 致命的 → __________ 3. 生存 → __________ 4. 实验 → __________ 5. 试验 → __________ 6. 有限的 → __________ 7. 智慧 → __________ 8. 有益的 → __________ 9. 细菌 → __________ 10. 充电 → __________ 【答案与解析】 子题A（英译中）： 1. republic — 共和国 2. deadly — 致命的 3. survival — 生存 4. broad — 广泛的 5. intend — 想要 6. herb — 药草 7. experiment — 实验 8. trial — 试验 9. limited — 有限的 10. sufficient — 足够的 11. data — 数据 12. wisdom — 智慧 13. beneficial — 有益的 14. conduct — 实施 15. bacteria — 细菌 16. indicate — 表明 17. accident — 意外 18. intelligent — 聪明的 19. theory — 理论 20. charge — 充电 子题B（中译英）： 1. republic 2. deadly 3. survival 4. experiment 5. trial 6. limited 7. wisdom 8. beneficial 9. bacteria 10. charge 题型2：词形变换（10题） 1.

He studied malaria, a deadly disease that threatened the survival of millions of people. He did not intend to become famous, but he had a broad interest in medicine and read many books. One day he noticed that a common herb seemed to kill the germs, so he began to refer to his old notes and planned a careful experiment. The early results were limited, and the cost was too high for his poor household. He could not postpone the work, because people were waiting for help. With sufficient time and patience, the project began to speed up, and at last his efforts began to pay off. Every small error taught him something new, and through trial and error he gained real wisdom. The story shows that patience and careful observation are the keys to every great discovery in the world of science today. The new medicine proved beneficial to thousands of patients, and the scientists learned how to conduct larger tests. They could illustrate the results with clear pictures, and the success was not a lucky accident; it was not made by accident at all. The discovery of penicillin came from a piece of mould that killed the bacteria around it, and the team was surrounded by many helpers. The results clearly indicate that nature often gives us hints, and only an intelligent mind can see them. Even a politician understood the importance, and lightning of genius strikes like real electricity. According to the new theory, a sudden thunderstorm of ideas can hit the mind, and the ribbon of discovery is tied with metal and hard work. You can charge a battery with electric energy, and a discovery can arrive with a bang. Every experiment, whether it succeeds or fails, adds a new piece to the great puzzle of knowledge. Such great work made the scientist a standout figure in the atomic age, though he feared that a bomb might bring evil to the world. Science can involve great risks, and every scientific advance deserves credit. There is a moral question about how to apply this new power, and we must never take it for granted that science is always safe. The mystery of nature should never let sb. down; only ignorance does. as to the future, we should protect our intellectual freedom and use the new power with authority and care. Each person has a responsibility to think, and we should declare our beliefs openly whatever our nationality is. New ideas are put forward every day, and the evolution of science continues. Many books are published each year to record the great marriage between science and humanity. Science and kindness together can build a better world for the children of tomorrow. The teacher asked us to guess a word from the text; we learned that theory means an idea that explains how something works, based on careful study. 1. Why did the scientist begin his careful experiment at first? A. Because he noticed a herb that seemed to kill the germs. B. Because he wanted to be famous. C. Because he needed more money. D. Because he liked travelling. 2. What does the underlined word 'theory' most probably mean in the text? A. An idea that explains how something works, based on careful study. B. A kind of medicine. C. A school subject. D. A type of machine. 3. How did the scientist gain real wisdom according to the passage? A. By giving up early. B. By sleeping a lot. C. Through trial and error. D. By buying books only. 4. What does the writer worry about science? A. It is too expensive. B. It will stop the evolution of the world. C. It makes people lazy. D.

He worked in a quiet province with a broad knowledge of medicine. He did not intend to discover a miracle, but he noticed that some extract of a common herb seemed to kill the germs. He began to refer to his old notes and planned a careful experiment. After many trials, the results were still limited, and the cost was too high for a poor household. He needed a bigger container and could not postpone the tests any longer. With sufficient data from the lab, the project began to speed up, and finally his hard work began to pay off. Every error taught him something new, and through trial and error he gained real wisdom. He wrote down every small change in the lab and never gave up, because he believed that even the smallest step could lead to a great result one day. The new medicine proved beneficial to thousands of patients. Scientists learned how to conduct the tests and could illustrate the results clearly. The famous discovery of penicillin came from a piece of mould that killed the bacteria around it. The team was surrounded by unexpected helpers, and they realized that nature often gives us hints. The results clearly indicate that such a lucky accident was not really by accident at all. It needed an intelligent mind to see the value, and favour smiled on those who worked hard. Even a politician could see the importance, because lightning of genius strikes like real electricity. According to a new theory, a sudden thunderstorm of ideas can hit the mind, and the ribbon of discovery is tied with metal and hard work. You can charge a battery with electric energy, and the sudden bang of an idea can arrive with a bang. Great discoveries often come to those who keep their eyes open and their minds ready at any moment. Such great discoveries made the scientist a standout figure in the atomic age, though he feared that a bomb might bring evil to the world. Science can involve great risks, and every scientific advance deserves credit. There is also a moral question: how should we apply this new power? We must not negate the value of life, and we should protect our intellectual freedom. The mystery of nature should never let sb. down; only ignorance does. as to the future, we should never take it for granted that science is always safe. True freedom comes with authority and respect. The law may permit some uses, but each person has a responsibility to think carefully. We should declare our beliefs openly, whatever our nationality is. New ideas are put forward every day, and the evolution of science continues. Many books are published each year, and the story of every great marriage between science and humanity is worth reading. Scientists remind us that curiosity and honesty are the best friends of progress, and they guide us toward a brighter future for all people. B. 语境串记单词（汉语译文） 1928 年，在一个欧洲小(republic)共和国里，一位科学家正在研究(malaria)疟疾，这是一种威胁数百万人(survival)生存的(deadly)致命疾病。他在一个安静的(province)省份工作，拥有(broad)广泛的医学知识。他并没有(intend)打算发现奇迹，但他注意到一种普通(herb)药草的(extract)提取物似乎能杀死病菌。他开始(refer to)查阅旧笔记，并计划进行一项仔细的(experiment)实验。经过多次(trial)试验，结果仍然(limited)有限，而且费用对贫穷的(household)家庭来说太高了。他需要更大的(container)容器，不能再(postpone)推迟试验了。有了实验室(sufficient)充足的(data)数据，项目开始(speed up)加速，最终他的努力开始(pay off)奏效。每一个(error)错误都教会他新的东西，(through trial and error)通过反复试验，他获得了真正的(wisdom)智慧。 新药被证明对数以千计的病人(beneficial)有益。科学家们学会了如何(conduct)进行测试，并能清楚地(illustrate)说明结果。著名的(penicillin)青霉素发现来自一块杀死了周围(bacteria)细菌的(mould)霉菌。团队被意想不到的帮手(surround)围绕，他们意识到大自然常常给我们提示。结果清楚地(indicate)表明，这样幸运的(accident)意外并非真的(by accident)偶然。它需要一个(intelligent)有才智的头脑看到其价值，(favour)幸运眷顾那些努力工作的人。甚至(politician)政治家也能看到其重要性，因为天才的(lightning)闪电像真正的(electricity)电一样击中人心。根据一种新(theory)理论，思想的(thunderstorm)雷暴会突然袭来，发现的(ribbon)丝带是由(metal)金属和辛勤工作系在一起的。你可以用(electric)电的能量给电池(charge)充电，一个想法的突然(bang)巨响可能(with a bang)引人注目地到来。 如此伟大的发现使这位科学家成为(atomic)原子时代的(standout)杰出人物，尽管他担心(bomb)炸弹会给世界带来(evil)罪恶。科学可能(involve)涉及巨大风险，每一项(scientific)科学进步都值得(credit)赞扬。还有一个(moral)道德问题：我们应该如何(apply)应用这种新力量？我们不能(negate)否定生命的价值，应该保护我们的(intellectual)智力自由。自然的(mystery)神秘不应(let sb. down)辜负我们；只有(ignorance)无知才会。(as to)至于未来，我们不应(take it for granted)理所当然地认为科学总是安全的。真正的(freedom)自由伴随着(authority)权威和尊重。法律可能(permit)允许某些用途，但每个人都有(responsibility)责任去仔细思考。无论我们的(nationality)国籍是什么，我们都应该公开(declare)表明自己的信念。每天都有新想法被(put forward)提出，科学的(evolution)进化仍在继续。每年有许多书被(publish)出版，科学与人性每一次伟大(marriage)结合的故事都值得一读。 第二部分：词形转变表 序号 原词 词形变化 1 deadly adj.致命的 dead (adj.) 死的；death (n.) 死亡 2 survive v.生存 survival (n.) 生存；survivor (n.) 幸存者 3 broad adj.广泛的 broadly (adv.) 广泛地；broaden (v.) 加宽 4 intend v.想要 intention (n.) 意图；intended (adj.) 打算中的 5 extract v.提取 extraction (n.) 提取；extracted (过去式) 6 experiment n.实验 experimental (adj.) 实验的；experimentation (n.) 实验 7 limit v.限制 limited (adj.) 有限的；limitation (n.) 限制 8 sufficient adj.足够的 sufficiently (adv.) 足够地；sufficiency (n.) 充足 9 wisdom n.智慧 wise (adj.) 明智的；wisely (adv.) 明智地 10 beneficial adj.有益的 benefit (n.) 益处；beneficially (adv.) 有益地 11 conduct v.实施 conduction (n.) 传导；conducted (过去式) 12 indicate v.表明 indication (n.) 迹象；indicator (n.) 指示器 13 intelligent adj.聪明的 intelligence (n.) 智力；intelligently (adv.) 聪明地 14 theory n.理论 theoretical (adj.) 理论的；theoretically (adv.) 理论上 15 electric adj.电的 electricity (n.) 电；electrical (adj.) 电气的 16 involve v.涉及 involved (adj.) 参与的；involvement (n.) 参与 17 apply v.应用 application (n.) 应用；applicable (adj.) 适用的 18 publish v.出版 publication (n.) 出版；published (过去式) 第三部分：梯度复现与多题型练习 题型1：英汉互译（30题） 乐思英语 ·语境串记单词 第 6 / 12 页 学科网（北京）股份有限公司 子题A：英译中（20个） 1. republic → __________ 2. deadly → __________ 3. survival → __________ 4. broad → __________ 5. intend → __________ 6. herb → __________ 7. experiment → __________ 8. trial → __________ 9. limited → __________ 10. sufficient → __________ 11. data → __________ 12. wisdom → __________ 13. beneficial → __________ 14. conduct → __________ 15. bacteria → __________ 16. indicate → __________ 17. accident → __________ 18. intelligent → __________ 19. theory → __________ 20. charge → __________ 子题B：中译英（10个） 1. 共和国 → __________ 2. 致命的 → __________ 3. 生存 → __________ 4. 实验 → __________ 5. 试验 → __________ 6. 有限的 → __________ 7. 智慧 → __________ 8. 有益的 → __________ 9. 细菌 → __________ 10. 充电 → __________ 题型2：词形变换（10题） 1.

He studied malaria, a deadly disease that threatened the survival of millions of people. He did not intend to become famous, but he had a broad interest in medicine and read many books. One day he noticed that a common herb seemed to kill the germs, so he began to refer to his old notes and planned a careful experiment. The early results were limited, and the cost was too high for his poor household. He could not postpone the work, because people were waiting for help. With sufficient time and patience, the project began to speed up, and at last his efforts began to pay off. Every small error taught him something new, and through trial and error he gained real wisdom. The story shows that patience and careful observation are the keys to every great discovery in the world of science today. The new medicine proved beneficial to thousands of patients, and the scientists learned how to conduct larger tests. They could illustrate the results with clear pictures, and the success was not a lucky accident; it was not made by accident at all. The discovery of penicillin came from a piece of mould that killed the bacteria around it, and the team was surrounded by many helpers. The results clearly indicate that nature often gives us hints, and only an intelligent mind can see them. Even a politician understood the importance, and lightning of genius strikes like real electricity. According to the new theory, a sudden thunderstorm of ideas can hit the mind, and the ribbon of discovery is tied with metal and hard work. You can charge a battery with electric energy, and a discovery can arrive with a bang. Every experiment, whether it succeeds or fails, adds a new piece to the great puzzle of knowledge. Such great work made the scientist a standout figure in the atomic age, though he feared that a bomb might bring evil to the world. Science can involve great risks, and every scientific advance deserves credit. There is a moral question about how to apply this new power, and we must never take it for granted that science is always safe. The mystery of nature should never let sb. down; only ignorance does. as to the future, we should protect our intellectual freedom and use the new power with authority and care. Each person has a responsibility to think, and we should declare our beliefs openly whatever our nationality is. New ideas are put forward every day, and the evolution of science continues. Many books are published each year to record the great marriage between science and humanity. Science and kindness together can build a better world for the children of tomorrow. The teacher asked us to guess a word from the text; we learned that theory means an idea that explains how something works, based on careful study. 1. Why did the scientist begin his careful experiment at first? A. Because he noticed a herb that seemed to kill the germs. B. Because he wanted to be famous. C. Because he needed more money. D. Because he liked travelling. 2. What does the underlined word 'theory' most probably mean in the text? A. An idea that explains how something works, based on careful study. B. A kind of medicine. C.
