0–3 分鐘：校準句
句子：In my view, the main POINT is simple, but the details matter.
標註：In my VIEW / the main POINT is SIMple / but the deTAILS MATter.
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
- but 前後形成邊界（前段半終止、後段終止）
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（/æ/–/ʌ/ 對立）
句子：NASA plans to send astronauts back to the Moon by 2025, but funding cuts could undermine the entire program.
標註：NASA PLANS / to SEND AStronauts / BACK to the MOON / by twenty twenty-FIVE / but FUNDing CUTS / could underMINE / the enTIRE PROgram.
操作化目標：
- NASA /ˈnæsə/ 的 /æ/ 開口大，舌位低
- astronauts /ˈæstrənɔːts/ 的 /æ/ vs. funding /ˈfʌndɪŋ/ 的 /ʌ/
- back /bæk/ 的 /æ/ vs. undermine /ˌʌndəˈmaɪn/ 的 /ʌ/
- to（兩次）、the（兩次）、but、could 弱讀
- BACK_to、CUTS_could 連結
- PROgram 句尾核重音並下降終止
句 2（/æ/–/ʌ/ 延伸）
句子：【BUNDLE】Some argue that the hundred billion dollars spent on Mars missions could tackle poverty and hunger on Earth instead.
標註：Some ARgue / that the HUNdred BILlion DOLlars / SPENT on MARS MISsions / could TACKle POVerty and HUNger / on EARTH inSTEAD.
操作化目標：
- that /ðæt/ 的 /æ/（非弱讀時）
- tackle /ˈtækl/ 的 /æ/ vs. hundred /ˈhʌndrəd/ 的 /ʌ/
- Mars /mɑːz/ 注意美式 /ɑː/
- that、on 弱讀
- that_the、on_Mars、on_Earth 連結
- inSTEAD 句尾下降終止
9–15 分鐘：超音段焦點與對比（2 句）
句 3（數據對比）
句子：The US government budgeted twenty-five billion for space exploration this year, not fifty billion.
讀法 A（強調 250 億這個數字）：
- 標註：The US GOVernment / BUDgeted TWENTY-five BILlion / for SPACE exPLOration / this YEAR / not fifty billion.
- 核重音在 TWENTY-five BILlion，末端下降終止
讀法 B（強調「不是 500 億」的否定）：
- 標註：The US government budgeted twenty-five billion / for space exploration this year / NOT FIFTY BILlion.
- 核重音轉移到 FIFTY，NOT 前語調略抬形成對比
句 4（立場保留＋轉折）
句子：Space telescopes like James Webb can discover distant planets, but critics question whether finding exoplanets should be a top priority when millions lack clean water.
讀法 A（轉折邊界清楚）：
- 標註：SPACE TELescopes / like JAMES WEBB / can disCOVer / DIStant PLANets / but CRItics QUEStion / whether FINDing EXoplanets / should be a TOP priORity / when MILlions LACK / CLEAN WAter.
- but 前半終止、後段重新起調；WAter 下降終止
讀法 B（焦點在優先順序質疑）：
- 標註：Space telescopes like James Webb can discover distant planets / but critics question / whether finding exoplanets should be a TOP priORity / when MILlions LACK CLEAN WAter.
- 核重音落在 TOP priORity 與 LACK，強調矛盾
15–20 分鐘：連續語流＋語篇模板（2 句）
句 5（縮約＋條件論述）
句子：If China had not made space a national priority, they would not have landed on the far side of the Moon, and the US would not be rushing to catch up now.
標註：If CHIna / had NOT made SPACE / a NAtional priORity / they would NOT have LANDed / on the FAR SIDE of the MOON / and the US / would NOT be RUSHing / to CATCH UP now.
連續語流目標：
- had_not 連結但 NOT 保持重音（強調）
- would_not（兩次）連結但 NOT 保持重音
- have_landed、to_catch 連結
- on_the 連結
- now 句尾核重音並下降終止
句 6（BUNDLE＋數據引用）
句子：【BUNDLE】The question is whether humanity should invest in colonizing Mars when we have not yet solved climate change, which threatens billions of lives here on Earth.
標註：The QUEStion is / whether huMANity should inVEST / in COLonizing MARS / when we have NOT yet SOLVED / CLImate CHANGE / which THREATens BILlions of LIVES / HERE on EARTH.
連續語流目標：

20–25 分鐘：語篇組織＋結論收束（2 句）
句 7（讓步轉折）
句子：Although SpaceX has advanced rocket technology dramatically, reducing launch costs by ninety percent, we must ask whether private companies should control access to space.
標註：AlTHOUGH SpaceX / has adVANCED ROCKet techNOLogy / draMATically / reDUcing LAUNCH COSTS / by NINEty perCENT / we must ASK / whether PRIvate COMpanies / should conTROL ACcess / to SPACE.
要點：
- Although 需獨立成語塊（前後各有邊界 150–250 ms）
- by ninety percent 需清楚傳達比例
- SPACE 句尾下降終止
句 8（結論＋建議）
句子：【BUNDLE】Given the current situation on Earth, the most balanced approach is to support both space science and urgent terrestrial needs, because progress in one area often benefits the other.
標註：GIVen the CURrent situAtion / on EARTH / the most BALanced aPPROACH / is to supPORT BOTH / SPACE SCIence / and URgent terREStrial NEEDS / beCASUE / PROgress in one Area / OFten BENefits the OTHer.

- Given the current situation 作為 BUNDLE 需獨立成語塊
- on、to、in 弱讀

- OTHer 句尾下降終止
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：tackle 的 /æ/ 聽成 /ʌ/） | （例：做 5 次 /æ/–/ʌ/ 極化對比） | （例：明天加入更多母音對比詞） |
| （例：although 前後沒清楚停頓） | （例：although 前後各加 200 ms） | （例：所有讓步連接詞強制獨立語塊） |

- 句 1：PROgram（計畫焦點）
- 句 2：inSTEAD（替代方案）
- 句 3A：BILlion / 句 3B：FIFTY
- 句 4A：WAter / 句 4B：LACK
