每日口說挑戰 【TED-Ed】下一個你想要探索的超能力是什麼呢？ (If superpowers were real: Super speed - Joy Lin)

今日挑戰句子

When the girl at rest, velocity equals zero miles per hour, begins accelerating to reach the speed within seconds, velocity increases rapidly to 25,000 miles per hour, her brain would crash into the side of her skull.

當女孩靜止時，速度等於每小時零英里。接著，速度在數秒內開始飆升，速率快速增加到每小時兩萬五千哩，她的大腦會撞進頭骨一側。
