Day 002 — 25 分鐘口說練習

今日主題：Renewable energy transition

【HF】高頻內容詞（12 個）：shift, replace, install, generate, supply, require, support, invest, develop, reduce, target, cost

【BUNDLE】高頻詞組（3 個）：

• The main challenge is that…
• This is partly because…
• According to recent data…

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（/θ/–/ð/ 對立）

句子：【HF】SHIFTING to renewable energy 【HF】REQUIRES both substantial 【HF】INVESTMENT and thoughtful planning, though the long-term benefits outweigh the initial 【HF】COSTS.

標註：SHIFTing to reNEWable ENergy / reQUIRES both subSTANtial inVESTment / and THOUGHTful PLANning / THOUGH the long-term BENefits / outWEIGH the iniTIAL COSTS.

操作化目標：

• thoughtful /ˈθɔːtfəl/ 清音 /θ/ vs. though /ðəʊ/ 濁音 /ð/ — 舌位相同但送氣不同
• the /ðə/ 濁音（4 次出現）需穩定
• both、with 的 /θ/ 需清楚
• to_renewable、though_the 連結
• COSTS 句尾核重音並下降終止

句 2（/θ/–/ð/ 延續）

句子：【BUNDLE】The main challenge is that weather-dependent sources like solar and wind can’t 【HF】SUPPLY steady power without either battery storage or thermal backup systems.

標註：The main CHALlenge is / that WEAther-dePENdent SOURces / like SOlar and WIND / can’t supPLY STEAdy POWer / without EIther BATtery STORage / or THERmal BACKup SYStems.

操作化目標：

• weather /ˈweðər/ 的 /ð/ vs. thermal /ˈθɜːməl/ 的 /θ/
• either /ˈaɪðər/ 或 /ˈiːðər/ 的 /ð/ 需清楚
• that 弱讀 /ðət/
• can’t 的 /t/ 需輕彈或省略但不影響否定意義
• SYStems 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：Solar capacity 【HF】INCREASED by two hundred gigawatts globally last year, not twenty gigawatts.

讀法 A（強調 200 GW 的規模）：

• 標註：SOlar caPAcity / inCREASED / by two HUNdred GIgawatts / GLObally last YEAR / not twenty gigawatts.
• 核重音在 HUNdred，末端下降終止
• twenty gigawatts 弱讀、縮短

讀法 B（強調「不是 20 GW」的否定）：

• 標註：Solar capacity / increased by two hundred gigawatts / globally last year / NOT TWENty GIgawatts.
• 核重音轉移到 TWENty，NOT 前語調略抬形成對比
• GIgawatts 強下降終止

句 4（政策立場＋轉折）

句子：Wind power 【HF】GENERATES clean electricity efficiently, but local opposition to turbine 【HF】INSTALLATION remains a major barrier in many regions.

讀法 A（轉折邊界清楚）：

• 標註：WIND POWer / GENerates clean elecTRIcity eFFIciently / but LOcal oppOSition / to TURbine instALLation / remains a MAjor BARrier / in many REgions.
• but 前半終止、後段重新起調
• REgions 下降終止

讀法 B（焦點在地方反對）：

• 標註：Wind power generates clean electricity efficiently / but LOcal oppOSition / to turbine installation / remains a MAjor BARrier / in many regions.
• 核重音落在 oppOSition 與 BARrier
• 強調阻礙的嚴重性

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】INVESTED in grid modernization earlier, we wouldn’t be facing such severe integration challenges now — but we didn’t, and that’s why renewable 【HF】TARGETS keep getting delayed.

標註：If we’d inVESted / in GRID modernIzation EARlier / we wouldn’t be FAcing / such seVERE / inteGRAtion CHALlenges NOW / but we DIDN’T / and that’s WHY / renewable TARgets / keep getting deLAYED.

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）
• that’s /ðæts/（that is 縮約）
• invested_in、wouldn’t_be、that’s_why 連結
• deLAYED 句尾核重音並下降終止

句 6（BUNDLE＋數據引用）

句子：【BUNDLE】This is partly 【HF】BECAUSE 【HF】INSTALLING offshore wind farms 【HF】COSTS three to four times more than onshore projects — 【BUNDLE】according to recent data, the average is roughly five thousand dollars per kilowatt.

標註：This is PARTly beCACUSE / inSTALLing OFFshore WIND farms / COSTS three to FOUR times MORE / than ONshore PROjects / acCORding to REcent DAta / the AVerage is ROUGHly / five THOUSand DOLlars / per KILowatt.

連續語流目標：

• This_is 連結
• because 不可吞掉，成為新語塊起點
• three_to_four、according_to 連結
• is_roughly 連結
• KILowatt 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 battery technology has improved dramatically, lithium-ion systems still 【HF】COST too much for utility-scale storage; however, new solid-state designs 【HF】DEVELOPED in the past two years show real promise.

標註：AlTHOUGH / BATtery techNOLogy / has imPROVED draMAticly / lithium-Ion SYStems / still COST too MUCH / for uTIlity-SCALE STORage / howEVer / new SOlid-STATE deSIGNS / deVELoped in the PAST two YEARS / show REAL PROmise.

要點：

• Although 與 however 必須獨立成短語塊（前後各有邊界停頓 150–250 ms）
• still COST 帶強調（持續性問題）
• PROmise 句尾下降終止，傳達希望語氣

句 8（therefore＋結論）

句子：Solar and wind now 【HF】GENERATE nearly forty percent of electricity in some European countries — therefore, the idea that renewables can’t 【HF】REPLACE fossil fuels is no longer 【HF】SUPPORTED by the evidence.

標註：SOlar and WIND / now GEnerate / nearly FORty perCENT / of elecTRIcity / in SOME EuroFEan COUNtries / THEREfore / the iDEa / that reNEWables CAN’T rePLACE / FOS sil FUels / is no LONger supPORTed / by the EVidence.

要點：

• therefore 獨立成語塊（前後各 150–250 ms 停頓）
• CAN’T 帶對比重音（反駁錯誤觀點）
• no longer 需清楚傳達「過去是、現在不是」的時間對比
• EVidence 句尾核重音並下降終止
