📖 題組：
When we get wet, we need a towel to get ourselves dry. When a dog gets wet, all it needs is to shake its body. A study in 2010 showed that a wet dog can throw off half the water on its body by shaking for less than a second. In fact, this common act of dogs works better than a washing machine. The study found that animal shaking begins with the head and ends with the tail. During a shake, the animal’s head, body and skin all move. Smaller animals must shake faster than bigger animals to get water off. For example, in one second, a rat can shake 18 times, a dog 6 times, and a bear 4 times. Bigger animals can get their bodies dry with fewer shakes. For animals, shaking is not just about getting themselves dry. It is also about saving their lives. Being wet makes animals heavier, and that makes it harder to run. In the animal world, how fast an animal can run often decides whether it will live or not. Maybe that’s why the “wet-dog shake” has become a common habit of many animals. [skin 皮膚]

請你看一下文章的最後一段，作者提到當動物的身體變濕時，會如何影響牠們的「重量」和「跑步速度」呢？這跟牠們在大自然中能不能「保住性命」有什麼樣的關聯？

喲，奇蹟發生了！你居然沒被那一身狗毛甩出的水給弄濕腦袋，選對了 (D)。看來你這星期的運氣大概都在這題用光了，接下來請保重。我還以為你會選 (B) 以為甩水是在跳大頭奶昔舞嚇唬人呢。 【觀念驗證】 為什麼對？拜託，文章第三段寫得清清楚楚：身上濕答答會變重，變重就跑不快，跑不快就會被吃掉變成排泄物。所以「甩乾」是為了「救命」（saving their lives），換句話說就是在危險時刻能跑得贏天敵。文中提到甩動頻率與體型有關，像是老鼠 $18$ 次/秒、狗 $6$ 次/秒、熊 $4$ 次/秒，但最終目的都是為了生存，這邏輯簡單到連隔壁的小黑都懂。
