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/

- 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（/iː/–/ɪ/ 對立）
句子：Freshwater 【HF】SUPPLY is decreasing globally while demand continues to 【HF】INCREASE, creating severe 【HF】SHORTAGES in regions already facing water stress.
標註：FRESHwater supPLY / is deCREASing GLObally / WHILE deMand conTINues / to inCREASE / creATing seVERE SHORtages / in REgions / alREAdy FAcing / WAter STRESS.
操作化目標：

- STRESS 句尾核重音並下降終止
句 2（/iː/–/ɪ/ 延續）
句子：【BUNDLE】A major concern is that agriculture 【HF】CONSUMES seventy percent of global freshwater, yet inefficient 【HF】IRRIGATION systems waste nearly half of this 【HF】RESOURCE.
標註：A MAjor conCERN is / that AGriculture / conSUMES SEVenty perCENT / of GLObal FRESHwater / YET ineffiCIent irriGAtion SYStems / WASTE NEARly HALF / of this reSORCE.
操作化目標：
- is /ɪz/ vs. systems /ˈsɪstəmz/ 的 /ɪ/ vs. resource /rɪˈsɔːs/ 或 /ˈriːsɔːs/ 的差異

9–15 分鐘：超音段焦點與對比（2 句）
句 3（數據對比）
句子：The Middle East 【HF】WITHDRAWS ninety percent of available water 【HF】RESOURCES annually, not fifty percent.
讀法 A（強調 90% 的極高比例）：
- 標註：The MIDdle EAST / withDRAWS / NINEty perCENT / of aVAIlable WAter reSORces / ANnually / not fifty percent.
- 核重音在 NINEty，末端下降終止
- fifty percent 弱讀、縮短
讀法 B（強調「不是 50%」的否定）：
- 標註：The Middle East / withdraws ninety percent / of available water resources annually / NOT FIFty perCENT.
- 核重音轉移到 FIFty，NOT 前語調略抬形成對比
- perCENT 強下降終止
句 4（問題＋轉折）
句子：Desalination plants 【HF】SUPPLY clean water reliably, but they 【HF】CONSUME enormous energy and 【HF】DISTRIBUTE concentrated brine that harms marine ecosystems.
讀法 A（轉折邊界清楚）：
- 標註：DesalinAtion PLANTS / supPLY CLEAN WAter / reLIably / but they conSUME / eNORmous ENergy / and disTRIbute / CONcentrated BRINE / that HARMS / maRINE ecoSYStems.
- but 前半終止、後段重新起調
- ecoSYStems 下降終止
讀法 B（焦點在環境成本）：
- 標註：Desalination plants supply clean water reliably / but they CONSUME / eNORmous ENergy / and distribute concentrated BRINE / that HARMS marine ecosystems.
- 核重音落在 CONSUME 與 HARMS
- 強調負面影響
15–20 分鐘：連續語流＋語篇模板（2 句）
句 5（縮約＋條件句）
句子：If farmers had adopted drip 【HF】IRRIGATION decades ago, we could’ve 【HF】CONSERVED billions of gallons — but they didn’t, and now aquifers are depleting faster than they can recharge.
標註：If FARmers / had aDOPted / DRIP irriGAtion / DEcades aGO / we could’ve conSERVED / BILlions of GALlons / but they DIDN’T / and NOW / Aquifers are dePLEting / FASTer than they can reCHARGE.
連續語流目標：
- had_adopted 連結，had 弱讀
- could’ve /ˈkʊdəv/（could have 縮約）
- didn’t /ˈdɪdnt/（did not 縮約）
- could’ve_conserved、they_didn’t 連結
- reCHARGE 句尾核重音並下降終止
句 6（BUNDLE＋因果）
句子：【BUNDLE】The root 【HF】CAUSE is that cities, agriculture, and industry 【HF】COMPETE for limited water 【HF】SUPPLIES — Singapore addressed this by 【HF】TREATING and 【HF】RECYCLING wastewater to meet forty percent of demand.
標註：The ROOT CAUSE is / that CIties / AGriculture / and INdustry / comPETE / for LIMited WAter supPLIES / SINgapore adDRESSED this / by TREATing and reCYcling WASTEwater / to MEET FORty perCENT / of deMand.

- The_root_cause_is 作為 BUNDLE 流暢讀出
- that_cities、and_industry 連結
- by_treating_and_recycling 流暢連結
- deMand 句尾核重音並下降終止
20–25 分鐘：語篇組織＋結論收束（2 句）
句 7（although/however＋讓步轉折）
句子：Although rainwater harvesting can supplement urban water 【HF】SUPPLIES affordably, it cannot replace centralized systems in high-density areas; however, combining both approaches reduces pressure on aging 【HF】INFRASTRUCTURE.
標註：AlTHOUGH / RAINwater HARvesting / can SUPplement / URban WAter supPLIES / afFORDably / it CANnot rePLACE / CENtralized SYStems / in high-DENsity Areas / howEVer / comBINing BOTH aPPROACHes / reDUces PRESSure / on Aging infraSTRUCture.
要點：
- Although 與 however 必須獨立成短語塊（前後各有邊界停頓 150–250 ms）
- CANnot 帶限制意味
- infraSTRUCture 句尾下降終止
句 8（therefore＋結論）
句子：【BUNDLE】This highlights the need for integrated water management — therefore, policies that 【HF】ALLOCATE water based on efficiency rather than historical rights, while investing in smart metering and leak detection, offer the most sustainable pathway.
標註：This HIGHlights the NEED / for inteGRAted WAter MAnagement / THEREfore / POlicies / that Allocate WAter / BASED on effICiency / rather than hisTORical RIGHTS / while inVESTing / in SMART MEtering / and LEAK deTECtion / OFfer the MOST / susTAINable PATHway.

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：is/east 混淆） | （例：做 5 次 /iː/–/ɪ/ 對比練習） | （例：明天加入更多 /iː/–/ɪ/ 對比） |
| （例：therefore 前後沒停頓） | （例：therefore 前後各加 200 ms） | （例：所有連接詞強制獨立語塊） |

- 句 1：STRESS（水資源壓力）
- 句 2：reSORCE（浪費焦點）
- 句 3A：NINEty / 句 3B：FIFty
- 句 4A：ecoSYStems / 句 4B：HARMS
