答案: D. How some animals survive winter by slowing their bodies down
The professor explains hibernation and torpor as ways animals survive winter without eating.
听力原文
Professor: Today I want to talk about how some animals survive the winter without eating. You've probably heard of hibernation. When an animal hibernates, its body temperature drops and its heart beats much more slowly. This saves a lot of energy. A ground squirrel, for example, may breathe only a few times a minute. But here's something surprising. Hibernating animals don't stay in that state the whole winter. Every week or two, many of them warm up for a short time, often less than a day, and then cool down again. Scientists aren't completely sure why. One idea is that the animals need these breaks so their immune systems can work properly. Now, bears are a bit different. A bear's body temperature drops only a few degrees, so some scientists prefer to call its winter sleep torpor rather than true hibernation. Even so, a bear can go months without eating or drinking, living on the fat it stored in the fall.
