9–15 分鐘：超音段焦點與對比（2 句）

句 3（數據對比）

句子：Neuralink aims to increase brain-computer bandwidth to one megabit per second, not one kilobit.

讀法 A（強調 1 兆位元這個數字）：

• 標註：NeuraLINK AIMS / to inCREASE / BRAIN-comPUter BANDwidth / to ONE MEGabit / per SECond / not one kilobit.
• 核重音在 ONE MEGabit，末端下降終止

讀法 B（強調「不是 1 千位元」的否定）：

• 標註：Neuralink aims / to increase brain-computer bandwidth / to one megabit per second / NOT one KIlobit.
• 核重音轉移到 KIlobit，NOT 前語調略抬形成對比

句 4（立場保留＋轉折）

句子：【BUNDLE】This technology raises profound fairness concerns, because only wealthy individuals will access expensive enhancements, creating an unbridgeable divide between enhanced and unenhanced humans.

讀法 A（轉折邊界清楚）：

• REAsons 句尾下降終止

句 8（結論＋警告）

句子：Given these ethical complexities, the most responsible framework is to limit enhancements strictly to therapeutic purposes—treating diseases, not exceeding natural limits—because once society accepts non-therapeutic enhancement, there will be no clear stopping point, and humanity risks losing the shared biological foundation that defines our common dignity.

標註：GIVen these Ethical comPLEXities / the most resPONsible FRAMEwork / is to LIMit / enHANCEments STRICTly / to theraPEUtic PURposes / TREATing diSEASes / NOT exCEEDing NAtural LIMits / beCASUE / once soSIety acCEPTS / non-theraPEUtic enHANCEment / there will BE / NO CLEAR STOPping POINT / and huMANity RISKS LOsing / the SHARED bioLOgical founDAtion / that deFINES / our COMmon DIGnity.
