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（/æ/–/ʌ/ 對立）

句子：Attempts to replicate landmark studies have failed at alarming rates, undermining public trust in scientific claims.

標註：atTEMPTS / to REPlicate / LANDmark STUDies / have FAILED / at aLARMing RATES / underMINing PUBlic TRUST / in scienTIfic CLAIMS.

• have /hæv/ 的 /æ/（重讀時）
• alarming /əˈlɑːmɪŋ/ 的 /ə/ 和 /ɑː/
• undermining /ˌʌndəˈmaɪnɪŋ/ 的 /ʌ/ 舌位中央，較短
• public /ˈpʌblɪk/ 的 /ʌ/
• to、at、in 弱讀
• to_replicate、at_alarming 連結
• CLAIMS 句尾核重音並下降終止

句 2（/æ/–/ʌ/ 延伸）

句子：【BUNDLE】Recent studies indicate that fewer than half of published cancer research results can be reproduced, casting doubt on fundamental assumptions.

標註：REcent STUDies INdicate / that FEWer than HALF / of PUBlished CAncer reSEARCH reSULTS / can be reproDUCED / CASTing DOUBT / on fundaMENtal asSUMPtions.

操作化目標：

9–15 分鐘：超音段焦點與對比（2 句）

句 3（數據對比）

句子：A Nature survey found that seventy percent of researchers could not reproduce another scientist’s experiments, not seventeen percent.

讀法 A（強調 70% 這個數字）：

• 標註：A NATure SURvey FOUND / that SEVenty perCENT / of reSEARCHers / could NOT reproDUCE / aNOther SCIentist’s exPERiments / not seventeen percent.
• 核重音在 SEVenty perCENT，末端下降終止

讀法 B（強調「不是 17%」的否定）：

• 標註：A Nature survey found / that seventy percent of researchers / could not reproduce another scientist’s experiments / NOT SEVenteen perCENT.
• 核重音轉移到 SEVenteen，NOT 前語調略抬形成對比

句 4（立場保留＋轉折）

句子：【BUNDLE】The underlying problem is publish-or-perish pressure, which incentivizes quantity over quality, but reforming academic incentives requires systemic change that threatens entrenched interests.

讀法 A（轉折邊界清楚）：

• 標註：The underLYing PROBlem / is PUBlish-or-PErish PRESSure / which inCENtivizes / QUANtity over QUALity / but reFORMing / acaDEmic inCENtives / reQUIRES sysTEmic CHANGE / that THREATens / enTRENCHED INterests.
• but 前半終止、後段重新起調；INterests 下降終止

讀法 B（焦點在系統性改革困難）：

• 標註：The underlying problem is publish-or-perish pressure / which incentivizes quantity over quality / but reforming academic incentives / reQUIRES sysTEmic CHANGE / that THREATens enTRENCHED INterests.
• 核重音落在 sysTEmic CHANGE 與 enTRENCHED，強調改革阻力

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 journals required authors to share raw data and detailed methods, reproducibility rates would improve dramatically, but publishers resist transparency because proprietary methods generate competitive advantages.

標註：If JOURnals reQUIRED / AUthors to SHARE / RAW DAta / and deTAILED MEthods / reproduCIbility RATES / would imPROVE / draMATically / but PUBlishers reSIST / transPARency / beCASUE / proPRIEtary MEthods / GENeRate / comPEtitive adVANtages.

連續語流目標：

• required_authors、to_share 連結
• would_improve 連結
• and_detailed 連結
• adVANtages 句尾核重音並下降終止

句 6（BUNDLE＋論證）

句子：【BUNDLE】This undermines confidence in entire fields, because when foundational studies prove unreliable, every subsequent paper built on those results becomes suspect, wasting billions in research funding chasing false leads.

標註：This underMINES CONfidence / in enTIRE FIELDS / beCASUE / when foundAtional STUDies / PROVE unreLIAble / EVry subSEquent PAPer / BUILT on THOSE reSULTS / beCOMES susPECT / WASTing BILlions / in reSEARCH FUNDing / CHASing FALSE LEADS.

20–25 分鐘：語篇組織＋結論收束（2 句）

句 7（讓步轉折）

句子：Although preregistration and open-access data repositories have shown promise in improving transparency, adoption remains voluntary and inconsistent, with many researchers viewing these practices as burdensome rather than beneficial.

標註：AlTHOUGH / preregi STRAtion / and OPen-ACcess DAta / rePositories / have SHOWN PROMise / in imPROVing / transPARency / aDOPtion reMAINS / VOLuntary / and inconSIStent / with MAny reSEARCHers / VIEWing these PRACtices / as BURdensome / RATHer than benefIcial.

要點：

• Although 需獨立成語塊（前後各有邊界 150–250 ms）
• preregistration 需清楚發音
• and（兩次）弱讀
• benefIcial 句尾下降終止

句 8（結論＋建議）

句子：Given the scale of this crisis, the most effective intervention is mandatory pre-publication peer verification with independent replication before findings enter the literature, because credibility depends not on how many papers we publish, but on whether those papers report truths we can build upon.

標註：GIVen the SCALE / of this CRIsis / the most efFECtive / interVENtion / is MANdatory / pre-publiCAtion PEER / verifiCAtion / with indePENdent repliCAtion / beFORE FINDings / ENter the LIterature / beCASUE / crediBIlity dePENDS / NOT on HOW many PApers / we PUBlish / but on WHEther THOSE PApers / rePORT TRUTHS / we can BUILD uPON.
