Animals have different ways of protecting themselves against wintertime weather. Some animals grow heavy coats of fur or feathers, while others dig into the ground to find a warm wintertime home. Some animals spend the winter in a deep sleep because by going to sleep they avoid the time of the year when food is scarce and the temperatures are low. Their sleep is known as
hibernation
.
There is much about hibernation that puzzles scientists. For example, they are wondering how hibernation came into being. Some scientists have explored the possibility that animals release a chemical that starts them hibernating.
One thing that scientists are certain about is that animals hibernate only when it is cold. Hibernation is a seasonal practice.
Some animals that fall into a wintertime sleep are not true hibernators because they spend only a part of the cold season asleep. Bears, for example, can easily be awakened from their winter nap. They are not true hibernators.
Sometimes it is difficult to determine whether a particular animal is a true hibernator. For example, some mice hibernate, but others do not. The same is true of bats. Some of them hibernate. Other do not.
The underlined word "hibernation" in paragraph 1 means ______.
选项
A、a sleep to avoid eating
B、a temperature in cold weather
C、a sleep in the cold season
D、an animal to practice sleep in winter
答案
C
解析
第一段倒数第二句是对“hibernation”的解释,即“hibernation”是冬天气温太低时动物所采取的的通过睡眠的方式过冬的一种方法,C项符合题意,故选C。
