要點：
- 功能詞弱讀：in /ɪn/, my /maɪ→mɪ/, the /ðə/, is /ɪz→z/, but /bət/
- 句尾 MATter 下降終止，明確收束

三遍法：
- 第 1 遍：慢速，只求重音位置正確
- 第 2 遍：正常語速，加上自然節奏
- 第 3 遍：錄音一次
3–9 分鐘：音段對立（2 句）
句 1（/θ/–/ð/ 對立）

- the /ðə/ 在 saves the most 中需保留
- than_we 連結，we 弱讀
- LIVES 句尾核重音並下降終止
9–15 分鐘：超音段焦點與對比（2 句）
句 3（效能對比）
句子：Deworming programs cost three dollars per child treated, while some interventions cost thousands per life saved.
讀法 A（強調 3 美元）：
- 標註：DeWORMing PROgrams / cost THREE DOLlars / per CHILD TREated / while some interventions / cost thousands per life saved.
- 核重音在 THREE，saved 弱讀，句尾下降終止
讀法 B（強調數千美元對比）：

回饋（90 秒）
回聽今天錄的 8 句，記錄三欄：
| 欄 1：可理解度阻礙點 | 欄 2：可修正機制 | 欄 3：明日最小調整 |
|---|---|---|
| （例：the/that 的 /ð/–/θ/ 混淆） | （例：做 10 次 they–think、this–thick 對比） | （例：明天所有 /ð/ 震動聲帶、/θ/ 清音送氣） |
| （例：although 前後沒停頓） | （例：although 前後各加 200 ms） | （例：所有讓步詞強制邊界標記） |
韻律任務
今天選擇讓以下詞承擔核重音（每句僅一個主核重音）：
- 句 1：IMpact（影響最大化）
- 句 2：LIVES（拯救生命）
- 句 3A：THREE / 句 3B：SAVED
- 句 4A：VAlues / 句 4B：QUANtify
- 句 5：conNECtions（個人連結）

替換任務
保留句型骨架，替換關鍵詞練習其他議題：
有效利他 → 氣候慈善：
- deworming programs → carbon offset projects
- lives saved → emissions reduced
- measurable impact → climate metrics
- personal connections → local initiatives
有效利他 → 教育投資：
- cost per child → cost per student
- utilitarian perspective → human capital approach
- systemic injustice → educational inequality
