Find the words describing the environment and Chen's physical state. · Environment: _________________________ (e.g., dim light) · Physical State: _________________________ (e.g., numb hands) · Question: Why does the author describe these details? Activity 2: The "Sweet" Mystery (文本细读) Answer the questions: 1. Why did Chen Wangdao ask for brown sugar sauce? 2. What actually happened when he ate the zongzi? 3. Critical Thinking: The title says "The taste of truth is sweet." Does it literally mean the ink tasted like sugar? What is the deeper meaning? Step 2: Scientific Discovery in Text B (Medical Science) Activity 3: The Chain of Discovery (逻辑链条) Complete the flow chart based on Page 16: Messy lab ➔ Noticed mould growing ➔ Saw no bacteria around mould ➔ Found a substance killing bacteria ➔ Named it "_________" ➔ Later used to treat _________.

Prepare a 1-minute oral report for the next class. · Name: ________________ · Discovery: ________________ · Key Quality: ________________ 💡 Teacher's Note (教学建议) 1. 导入环节：可以利用墨汁蘸粽子的图片作为悬念导入，问学生："Have you ever eaten something weird while studying?" 活跃气氛。 2. 难点突破：Text A中的 "The taste of truth is sweet" 是隐喻，需引导学生从物质层面上升到精神层面。Text B中的 "accidental" 需要辩证看待，强调机会留给有准备的人。 3. 情感升华：最后总结时，可以将“伟人”定义为那些为了人类进步（无论是思想还是健康）而专注奉献的人。 学科网（北京）股份有限公司 $
