tedy bear Black Bear 黑熊1熊冬眠不是因为冷，而是因为没有食物熊不像青蛙那样进行完全冬眠，而是进入一种休眠状态，称为蛰伏。蛰伏和冬眠的主要区别是，在蛰伏状态下，动物很容易醒来。蛰伏是一种轻冬眠，在蛰伏状态时，它们的体温仅仅下降7~8摄氏度，心率从每分钟50次减到10次左右。Black Bears hibernate not because of the cold but because there is a lack of food during the winter months. Black Bears do not go into complete hibernation the way frogs do, however, they enter a state of dormancy in the winter, called torpor. The main difference between a torpor and a hibernation is that during a torpor the animal is easily awoken. It’s a kind of light hibernation. During torpor, their body temperature drops by only 7 or 8 degrees centigrade. Their heart rate slows from 50 beats per minute to about 10 beats per minute. bing 搜索关于熊冬眠的资料，妈妈备课:By the time the adult grizzly wakes up in the spring, her baby is strong enough to follow her out of the den.
