Do you know how animals spend their winter?The biggest problem for most animals in
winter is finding enough food.If an animal can not find enough insects or green plants and so on,it will choose to hibernate.This deep sleep helps them to save energy, and live through the winter with little or no food. Most hibernators prepare in some way for the winter. Some store food in their living places to eat when they awake for short periods. Many eat extra food in the fall. It is stored as body fat to be used later for energy. True hibernators go into such a deep sleep that they are difficult to wake and may appear dead. Their body temperature drops and breathing and heart beat slows down. If a hibernator'stemperature falls too low, it will awaken slightly and tremble to warm up a bit. The largest hibernators are the bears. Although a bear's heart rate may drop from a normal of 40-50 beats per minute down to 8-12,its temperature drops only slightly,allowing it to wake up quickly. These bears are also special because,unlike other hibernatiors, they do not ear or drink at all while hibernating, which can be as long as six months.新概念第二册第19课练习册短文,拜托哪位大神给翻译,请严谨些.
