【BUNDLE】高頻詞組（3 個）：

• Studies show that…
• The main driver is…

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：

1. 第 1 遍：慢速，只求重音位置正確
2. 第 2 遍：正常語速，加上自然節奏
3. 第 3 遍：錄音一次

3–9 分鐘：音段對立（2 句）

句 1（/s/–/ʃ/ 對立）

句子：Tropical forests 【HF】DISAPPEAR at an alarming 【HF】RATE, with an estimated ten million hectares 【HF】DESTROYED annually — an area roughly the 【HF】SAME size as South Korea.

標註：TROPical FORests / disaPPEAR / at an aLARMing RATE / with an EStimatED / ten MILlion HECtares / deSTROYED ANnually / an Area ROUGHly / the SAME SIZE / as South KoREa.

操作化目標：

• forests /ˈfɒrɪsts/ 結尾 /s/ vs. size /saɪz/ 的 /z/
• estimated /ˈestɪmeɪtɪd/ 的 /s/ vs. sure（若出現）的 /ʃ/
• same /seɪm/ 的 /s/ 需清楚（不可滑成 /ʃ/）
• with_an、roughly_the、same_size 連結
• KoREa 句尾核重音並下降終止

句 2（/s/–/ʃ/ 延續）

句子：【BUNDLE】The main 【HF】DRIVER is agriculture expansion, especially cattle ranching and soy cultivation, which 【HF】THREATENS countless 【HF】SPECIES that 【HF】DEPEND on forest ecosystems.

標註：The main DRIver / is aGRIculture exPANsion / esPECially CATtle RANCHing / and SOY cultiVAtion / which THREATens / COUNTless SPEcies / that dePEND / on FOrest ecoSYStems.

操作化目標：

• especially /ɪˈspeʃəli/ 的 /ʃ/ vs. species /ˈspiːʃiːz/ 的 /ʃ/
• ecosystems /ˈiːkəʊˌsɪstəmz/ 的 /s/ 需清楚
• which 弱讀 /wɪtʃ/
• countless_species、that_depend、on_forest 連結
• ecoSYStems 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（數據對比）

句子：The Amazon has 【HF】LOST seventeen percent of its original forest cover, not seven percent.

讀法 A（強調 17% 的嚴重性）：

• 標註：The Amazon / has LOST / sevenTEEN perCENT / of its orIGinal FOrest COVer / not seven percent.
• 核重音在 sevenTEEN，末端下降終止
• seven percent 弱讀、縮短

讀法 B（強調「不是 7%」的否定）：

• 標註：The Amazon / has lost seventeen percent / of its original forest cover / NOT SEven perCENT.
• 核重音轉移到 SEven，NOT 前語調略抬形成對比
• perCENT 強下降終止

句 4（因果＋轉折）

句子：Biodiversity hotspots 【HF】PROTECT over half of the world’s plant 【HF】SPECIES, but they’re 【HF】DISAPPEARING faster than we can study them.

讀法 A（轉折邊界清楚）：

• 標註：BioDIversity HOTspots / proTECT / over HALF / of the WORLD’S PLANT SPEcies / but they’re disaPPEARing / FASTer than we can STUdy them.
• but 前半終止、後段重新起調
• them 句尾下降終止

讀法 B（焦點在消失速度）：

• 標註：Biodiversity hotspots protect / over half of the world’s plant species / but they’re disaPPEARing / FASTer than we can STUdy them.
• 核重音落在 disaPPEARing 與 FASTer
• 強調時間緊迫性

15–20 分鐘：連續語流＋語篇模板（2 句）

句 5（縮約＋條件句）

句子：If we’d 【HF】PROTECTED critical habitats decades ago, thousands of 【HF】SPECIES wouldn’t be on the brink of extinction now — but we didn’t, and the 【HF】RATE of 【HF】LOSS continues to accelerate.

標註：If we’d proTECTed / CRItical HABitats / DEcades aGO / THOUsands of SPEcies / wouldn’t BE / on the BRINK / of exTINCtion NOW / but we DIDN’T / and the RATE of LOSS / conTINues to acCELerate.

連續語流目標：

• we’d /wiːd/（we had 縮約）
• wouldn’t /ˈwʊdnt/（would not 縮約）
• didn’t /ˈdɪdnt/（did not 縮約）
• we’d_protected、wouldn’t_be、we_didn’t 連結
• acCELerate 句尾核重音並下降終止

句 6（BUNDLE＋數據）

句子：【BUNDLE】【HF】STUDIES 【HF】SHOW that current extinction rates are one thousand times higher than natural background levels — 【BUNDLE】this has 【HF】LED to what scientists call the sixth mass extinction event.

標註：STUdies SHOW / that CURrent exTINCtion RATES / are one THOUsand TIMES HIGHer / than NAtural BACKground LEVels / this has LED / to what SCIentists CALL / the SIXTH MASS exTINCtion eVENT.

連續語流目標：

• that_current 連結
• one_thousand_times 流暢連結
• this_has_led 作為 BUNDLE 流暢讀出
• what_scientists 連結
• eVENT 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 reforestation programs 【HF】RESTORE some areas, they cannot replicate the biodiversity of old-growth forests; however, they do provide essential carbon storage and watershed 【HF】PROTECTION.

標註：AlTHOUGH / reforEStation PROgrams / reSTORE some Areas / they CANnot REPlicate / the bioDIversity / of OLD-growth FORests / howEVer / they DO proVIDE / essenTIAL CARbon STORage / and WATershed proTECtion.

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 與 DO 帶對比重音（限制 vs. 貢獻）
• proTECtion 句尾下降終止

句 8（therefore＋結論）

句子：Indigenous communities manage twenty-two percent of global forests yet safeguard eighty percent of remaining biodiversity — therefore, 【HF】PROTECTING their land rights is essential for conservation, not optional.

標註：inDIGenous comMUnities / MAnage / twenty-TWO perCENT / of GLObal FORests / YET safeguard / EIGHty perCENT / of reMAINing bioDIversity / THEREfore / proTECting their LAND RIGHTS / is esSENtial / for conserVAtion / NOT OPtional.

• YET 帶對比重音（少數管理 vs. 多數保護）
• therefore 獨立成語塊（前後各 150–250 ms 停頓）
• NOT 帶強對比重音（必要 vs. 可選）
• OPtional 句尾核重音並下降終止

• 句 1：KoREa（規模比較）
• 句 2：ecoSYStems（生態依賴）
• 句 3A：sevenTEEN / 句 3B：SEven

• 句 7：proTECtion（次要貢獻）
• 句 8：OPtional（強制對比）

替換任務

保留句型骨架，替換關鍵詞練習其他議題：

森林砍伐 → 語言消失：

• deforestation → language extinction
• biodiversity → linguistic diversity
• species → indigenous languages
• reforestation → language revitalization

森林砍伐 → 技能差距：

• habitat loss → skill obsolescence
• extinction rates → automation displacement
• conservation → workforce retraining
• indigenous knowledge → traditional expertise
