📖 題組：
A new study published in July 2024 reveals that climate change is causing Earth’s days to lengthen at an unprecedented rate. While Earth’s days have naturally been increasing by a few milliseconds per century due to lunar gravity, the melting of polar ice sheets is 41 this process significantly. 42 Arctic and Antarctic ice melts, the restructuring of mass from poles to equator is further flattening Earth’s shape. Since 2000, the day length has increased 43 about 1.33 milliseconds per century, up from 0.3-1.0 milliseconds in the 20th century. If greenhouse gas emissions continue unchecked, this rate could 44 2.62 milliseconds per century by 2100. Although people are generally 45 , these changes have important meanings for global timekeeping systems. The changes may require adjustments to Coordinated Universal Time (UTC), potentially affecting satellite navigation, telecommunications, trade, and space travel operations.

思路引導 VIP
請試著想像：當一位正在原地旋轉的芭蕾舞者突然將原本收攏的雙臂向外展開（模擬質量往赤道移動），她的旋轉速度會發生什麼變化？而這種旋轉速度的改變，對於「完成一圈所需的時間」會產生什麼樣的影響？

語意邏輯與因果判斷
恭喜你精準地掌握了文章的邏輯脈絡！這題的解題關鍵在於理解因果關係（Causality）。文中提到地球日長本來就會因為月球引力而增加，但後半段指出極地冰川融化會導致質量重新分配，使地球變得更扁平，進而導致日長增加的速度從原本的 0.3-1.0 毫秒提升至 1.33 甚至 2.62 毫秒。既然數據呈現上升趨勢，代表這個「日長變長」的過程正在被加速，因此選擇 speeding（加速）完全正確。
