Value of Science Core Connotation Supporting Evidence Practical Value Helps humans make things that improve life and solve problems. The development of medicine cures diseases; technology improves production efficiency. Intellectual Enjoyment Brings excitement and satisfaction from exploring natural mysteries. Humans are curious about the universe and nature; exploring the unknown brings ________. Freedom to Doubt Allows people to question authority and existing theories, leading to scientific progress. Science is not based on ________ but on doubt; questioning leads to new discoveries. 【答案】 intellectual pleasure；blind faith （三）精读・深层理解 Answer the following questions based on the passage. 1.Why does the speaker regard "freedom to doubt" as the greatest value of science? 2.How does the speaker’s personal experience (working on the atomic bomb) support his view on the value of science? 【答案】 1.Because freedom to doubt allows people to question existing theories and authority, which is the driving force behind scientific progress. Without doubt, science would stop developing and remain stagnant. 2.The speaker’s experience of working on the atomic bomb made him realize that science has both positive and negative practical values (it can be used for good or harm). This led him to reflect on the deeper values of science beyond practical use, such as intellectual enjoyment and freedom to doubt, which are more fundamental and lasting. 应用实践 （一）小组讨论：主题探究 Discuss the following questions in groups and share your ideas. 1.Do you agree that "freedom to doubt" is the core of scientific progress? Give examples to support your view. 2.How can we apply the values of science (practical value, intellectual enjoyment, freedom to doubt) in our study? 【答案】 1.Yes, I agree. For example, Copernicus doubted the traditional "geocentric theory" and proposed the "heliocentric theory", which changed human’s understanding of the universe. Another example is Einstein, who questioned Newton’s classical mechanics and put forward the theory of relativity, promoting the development of physics. These examples show that doubt is the starting point of scientific progress. 2.In our study, we can: ① Use the practical value of science by applying knowledge to solve real-life problems (e.g., using mathematical formulas to calculate daily expenses); ② Pursue intellectual enjoyment by being curious about knowledge and exploring the principles behind what we learn; ③ Exercise freedom to doubt by questioning textbook content and asking "why" to deepen understanding (e.g., questioning the conclusion of an experiment and repeating it to verify). （二）词汇与句型运用 Complete the passage with the correct forms of the words and phrases in the box.

First, its practical value gives rise to inventions that improve our daily lives, such as medical technology that cures diseases. Second, it brings intellectual enjoyment through the pursuit of natural mysteries, satisfying human curiosity. Third, the freedom to doubt is the core value of science. Science is based on questioning rather than blind faith, and this freedom leads to new discoveries. These values of science should be passed on to future generations to encourage continuous exploration. 【参考范文（作业二）】 The Importance of Freedom to Doubt in Study Freedom to doubt is crucial in study, as it helps us deepen understanding and pursue truth. Many students accept textbook knowledge without questioning, which limits their thinking. However, doubt can lead to deeper exploration. For example, when learning a physics formula, we can doubt its origin and verify it through experiments. This not only helps us remember the formula better but also understand its underlying principles. Another example is in history class: doubting a traditional view and researching different sources can help us form a more objective understanding. Freedom to doubt does not mean denying everything, but rather thinking independently. In study, we should cultivate the courage to question, ask more "why", and seek answers through research. This attitude will not only improve our academic performance but also foster critical thinking skills that are valuable for life. 1 学科网（北京）股份有限公司 $ Unit 4 Scientists who changed the world Period 4 Extended reading（导学案）原卷版 【学习目标】 1.掌握文本核心词汇及科学主题短语，能准确理解并运用。 2.理清演讲《The Value of Science》的逻辑脉络，通过精读提取科学的三大价值（实用价值、智力乐趣、质疑自由）的关键信息。 3.赏析文本中的道理论证、个人经历佐证等论证手法，体会其对支撑观点、增强说服力的作用。 4.深化对科学本质的认知，能结合文本探讨科学精神的核心，树立勇于质疑、追求真理的科学观。 5.提升议论性演讲语篇的解读能力，学会通过分析论点、论据把握作者的核心观点与写作意图。 【学习重难点】 教学重点 1.文本关键信息的提取与梳理，把握“引入 — 分述三大价值 — 总结”的逻辑结构。 2.核心词汇、短语的理解与搭配运用，以及论证手法的赏析。 教学难点 1.解读质疑自由作为科学核心价值的深层内涵，理解其对科学进步的意义。 2.结合文本与现实，辩证思考科学的价值与意义，践行科学精神。 【预习清单】 （一）核心词汇与短语填空 1./ˈvæljuː/n. & vt. ________（价值；重视） 2./ˌɪntəˈlektʃuəl/adj. ________（智力的；脑力的）n. 知识分子 3./ˈmɪstri/n. ________（奥秘；神秘事物） 4./daʊt/n. & vt. ________（怀疑；质疑） 5./ˈfriːdəm/n. ________（自由） 6./ˌkjʊəriˈɒsəti/n. ________（好奇心） 7.give rise ________（导致；引起） 8.in the pursuit ________（追求……） 9.be based ________（基于；以…… 为基础） 10.pass ________（传递；传承） （二）预习思考 1.浏览文本标题与开头段落，预测演讲主要探讨科学的哪些价值？ 2.结合常识，你认为科学精神的核心是什么？ 【学习过程】 学习理解 （一）略读・主旨与结构把握 Read the passage quickly and complete the structure outline.
