The Data She Would Not Delete Dr. Elena Park led a small engineering team that was developing a low-cost sensor for checking drinking water in remote villages. After months of work, the team finally produced a design that seemed ready for a public test. Most of the sensors gave similar readings, but one device repeatedly showed a much higher level of contamination. The deadline was close. A teammate argued that the unusual device was probably damaged and suggested removing its data from the report. Doing so would make the results look consistent and allow the team to present the product on time. Park refused. She said that an inconvenient result was still a result, and that the team had to understand it before making any claim about safety. Instead of discarding the reading, Park compared the testing conditions. She noticed that the device had been used in a room with unusually high humidity. The team then repeated the experiment with all sensors under dry and humid conditions. The pattern appeared again: humidity affected every sensor, although the effect was strongest in the device first considered faulty. The problem was not one bad sensor but a weakness in the whole design. The team redesigned the protective casing and repeated the tests. The new version remained stable in both conditions. Their presentation was delayed, and the final report included the failed readings, the design change and the limits of the new test. Park later explained that the delay was disappointing, but a fast answer would have been useless if it could not be trusted. The story shows that scientific progress does not depend only on clever ideas. It also depends on the honesty to report unwanted evidence, the patience to test an explanation, and the responsibility to place public safety above personal success. 1. Why did the teammate want to remove the unusual reading? A. The device was too expensive to repair. B. The reading made the results less consistent. C. The village refused to join the test. D. The team had already proved the design was safe. 2. What did the repeated experiment show? A. Only one sensor was damaged. B. Humidity affected the entire design. C. Dry conditions made every sensor fail. D. The first report had used the wrong water sample. 3. Which action most directly shows Park’s honesty? A. Leading a small engineering team. B. Designing a low-cost sensor. C. Keeping the failed readings in the final report. D. Feeling disappointed about the delay. 4. Why does the author mention public safety in the final paragraph? A. To explain why the sensor was expensive. B. To show the wider responsibility behind Park’s choice. C. To prove that deadlines are never important. D. To suggest that one test can guarantee safety. 5. Which statement best expresses the passage’s main idea? A. Scientific work requires both ability and responsible use of evidence. B. A successful scientist should avoid unexpected results. C. New technology is useful only in remote villages. D. Team disagreement always delays scientific progress. B2 语篇填空：From Example to Evidence [提高层] Read the passage and fill in each blank with one proper word or the correct form of the word in brackets. From Example to Evidence A strong paragraph about a scientist should do more than list achievements. It begins with a clear claim about a quality and then gives a specific event 1. __________ supports that claim. The writer should explain why the event is meaningful instead of expecting the reader 2. __________ (make) the connection alone. For example, saying that a researcher repeated an experiment is not enough. The paragraph becomes more convincing when it explains that the researcher continued 3. __________ several failures because reliable evidence mattered more than a quick result. Transitions also help the reader follow the reasoning. Words such as despite, therefore and rather than show relationships between difficulty, choice 4. __________ consequence. At the same time, writers should avoid 5. __________ (use) absolute words when the evidence is limited. A single event may reveal a quality, but it does not prove that a person acted in the same way in every situation. In a well-developed CEEL paragraph, the claim, evidence and explanation 6. __________ (connect) closely. The final link sentence returns to the main idea and shows how the example contributes to 7. __________ broader understanding of the scientific spirit. When each part has a clear function, the paragraph is not only 8. __________ (informative) but also more persuasive. C. 写作迁移 C1 为校英文杂志撰写“Scientific Spirit in Action” [培优层] Write an article of about 120 words based on the evidence card. Advanced learners may expand it to 140—170 words. Select two qualities and build at least one complete CEEL chain. Situation The school environmental club wanted to explain sudden air-quality changes in the library. Evidence 1 Chen Rui repeated the measurements at different times instead of reporting the first dramatic result. Evidence 2 She compared cleaning schedules and found that a spray caused short pollution spikes; poor ventilation was not the only explanation. Evidence 3 She recorded the limits of the small sample and refused to describe the conclusion as final. Outcome The school changed the cleaning time and the club shared the revised method with other classes. Possible qualities honesty · rigour · responsibility · patience · cooperation Planning Part Content My notes Opening Who is the person? What is your overall judgement? Body Quality 1 + evidence + explanation; Quality 2 + evidence + explanation Ending What does the story show about the scientific spirit? Writing area Self-check Self-check Yes Not yet I selected no more than two main qualities. □ □ Each quality is supported by a specific action. □ □ I explained why the action proves the quality. □ □ I used at least two logical connectors. □ □ My core article is about 120 words; an advanced version may be 140—170 words. □ □ A strong judgement grows from specific evidence and clear explanation. 学科网（北京）股份有限公司 $ 人教版高中英语选择性必修第二册 UNIT 1 SCIENCE AND SCIENTISTS Using Language 写作课分层作业（解析版） 姓名/班级/日期 __________________ __________________ __________________ 建议用时 25—30分钟 分层路径 基础层：A　｜　提高层：A+B　｜　培优层：A+B+C 作业目标 识别品质证据；强化CEEL论证；完成科学精神主题短文 说明：本作业配合教材第7—9页及Using Language写作课讲义使用。拓展语篇、语篇填空与写作人物卡均为本项目原创。 A. 基础达标 A1 品质、证据与解释辨析 [必做] Read the statements and write C (Claim/quality label), E (Evidence) or X (Explanation). 1. （　　）Dr. Lin was determined. 2. （　　）Although three early trials failed, she redesigned the apparatus and repeated the test eighteen times. 3. （　　）Her willingness to begin again shows that reliable results mattered more to her than quick success. 4. （　　）Professor Wu was honest. 5. （　　）When later evidence challenged his first model, he corrected the article publicly. 6. （　　）By admitting the error, he prevented other researchers from repeating the same mistake. 7.

CEEL 1 Claim: rigorous｜Evidence: repeated measurements and compared schedules｜Explanation: refused to treat one dramatic figure as a final conclusion CEEL 2 Claim: responsible and honest｜Evidence: recorded limits and revised the explanation｜Explanation: accuracy mattered more than producing an impressive report Ending Her work improved school practice and showed that careful evidence can lead to useful change. Useful links instead of; rather than; what made ... was ...; this action reveals ...; therefore 参考范文 Scientific Spirit in Action Chen Rui’s air-quality investigation shows that scientific spirit is not limited to professional laboratories. It can be seen in the way a student treats evidence. First, Chen Rui was rigorous. Instead of reporting the first dramatic reading, she repeated the measurements at different times and compared them with the library’s cleaning schedule. This careful process revealed that a cleaning spray caused short pollution spikes and that poor ventilation was not the only explanation. Her actions show that a reliable conclusion must grow from comparison rather than excitement. She was also responsible and honest. Chen Rui recorded the limits of the small sample and refused to present the result as final. What made this choice meaningful was that accuracy mattered more to her than an impressive report. As a result, the school changed the cleaning time, and other classes received a better method. Her story shows that rigour, honesty and responsibility can turn careful observation into practical improvement. 【结构解析】Opening提出总体判断；第一个CEEL链以“重复测量—比较日程”为证据证明rigour；第二个CEEL链以“记录局限—拒绝绝对结论”为证据证明responsibility和honesty；结尾回应scientific spirit并说明现实影响。 维度 分值 判定要点 任务完成 3 人物、两项品质、结尾认识完整 证据论证 3 具体行为与品质对应，并有Explanation 篇章语言 3 衔接清楚，词汇和句式准确 规范意识 1 核心任务约120词；培优可扩展至140—170词；不把有限证据写成绝对定论 【常见问题】①品质写得过多，导致每项都没有展开；②用生平罗列替代证据论证；③只写“this shows she was responsible”，没有解释行动与品质之间的逻辑；④结尾重复开头，没有说明科学精神的现实价值。 学科网（北京）股份有限公司 $
