动物节能
有的动物有特殊的节能本领，它们在遇到困难时，用冬眠、停止活动等方法来降低能量消耗。乌龟两年不吃食物，仍然会抬头观望，若无其事；鳄鱼七百天滴水不进，仍然行走自如；青蛙四百天不吃不喝，还能活着。蛇是变温动物，它直接利用太阳能，省去一些能量消耗。在冬季到来以前，它尽量多吃东西，把能量储存起来；它在冬眠时基本上处于静止状态，经过一百五十多天的冬眠，体重仅下降2%。

Animals and Energy Conservation
Some animals are skilled at conserving energy. For example, in the wintertime, many animals hibernate to decrease their energy consumption. Turtles that don’t eat for two years can still raise their head to look around. Crocodiles that don’t drink any water for 700 days can still walk freely. Frogs that don’t drink or eat for 400 days can still live. Snakes make use of solar heat to raise their body temperature and conserve energy. Before winter, snakes eat as much as possible, then remain still while hibernating. After 150 days of hibernation, their weight decreases by only two percent.
動物節能
有的動物有特殊的節能本領，它們在遇到困難時，用冬眠、停止活動等方法來降低能量消耗。烏龜兩年不吃食物，仍然會抬頭觀望，若無其事；鱷魚七百天滴水不進，仍然行走自如；青蛙四百天不吃不喝，還能活著。蛇是變溫動物，它直接利用太陽能，省去一些能量消耗。在冬季到來以前，它盡量多吃東西，把能量儲存起來；它在冬眠時基本上處於靜止狀態，經過一百五十多天的冬眠，體重僅下降2%。
