Winter in many places is very cold. There is lots of snow around, and the ground freezes, which can make life difficult for animals. People in cold places live in warm houses and have learned to adapt. What do animals do? (22) There are three main ways that animals survive the cold in winter; sleep, adapt or migrate.
Some animals, such as bears, frogs and snakes, sleep all winter. They sleep very deeply and need little or no food. (23) While sleeping, their body temperature drops, and their heart beat slows down. To prepare for this before winter, these animals eat extra food to become fat, which gives them the energy they need while they sleep.
Other animals adapt. For example, by staying active in winter. It is often hard for them to find food. (24) So some animals, such as mice, collect extra food before winter, and hide it. When winter comes, they return to the hiding places to eat the food. Some animals grow thicker fur, or live in tree holes or underground to stay warm.
Some birds migrate by flying to a warmer place for the winter, where they can find more food. Some fly very long distances, including one kind of bird that flies from the remote north of the world, all the way to the distant south. (25) Some birds fly in groups for safety, while others fly alone.
Questions 22 to 25 are based on the passage you have just heard.
22. What does the speaker say about animals in winter?
23. What do we learn about animals that sleep through winter?
24. How do animals like mice adapt to the severe winter?
25. Why do some birds fly in groups when migrating, according to the speaker?
选项
A、By staying in hiding places and eating very little.
B、By seeking food and shelter in people’s houses.
C、By growing thicker hair to stay warm.
D、By storing enough food beforehand.
答案
D
解析
浏览四个选项,从选项中的by可推测,此题与方式有关、题干问的是像老鼠一样的动物是如何适应严寒的冬天的。短文中提到,像老鼠一样的动物在冬天到来之前,它们会寻找额外的食物并储藏起来,当冬天到来时,它们就会到藏食物的地方吃东西,故答案为D。A项(呆在藏身的地方,几乎不吃东两)与原文不符,故排除。B项(在人类居住的家中寻找食物和避难所)原文未提及,故排除。C项(让毛发长得很厚来保温)与原文不符,原文不是指老鼠,故排除。
