Question

   Winter is coming. It's time for the arctic ground squirrel (北极松鼠) to get her underground home ready. Winter is long and cold in northern Canada. Plants can't grow so there are no leaves or grass for animals to eat. They must find other ways to live. The arctic ground squirrel “sleeps” the winter away.

   ① For months the ground squirrel has been eating lots of seeds mushrooms and berries. Now she is fat. The extra fat will keep her alive through the winter. At last she crawls through a tunnel (隧道) into the nest she has made. She curls up wraps her tail around herself and goes to “ sleep. ” Only she won’t really be sleeping. She will be hibernating.

   ② The ground squirrel's body is usually as warm as yours. When she hibernates her body becomes colder than ice. But she doesn’t freeze. Her heart beats just one or two times each minute. She will take only about three breaths each minute. These changes in the ground squirrel's body let her live through the winter. When she hibernates she doesn’t need much food.

   ③ The ground squirrel will not stay in hibernation all winter. Her body warms up and becomes active for a few hours once every few weeks. Over the winter these active times use up more than half of the energy that she worked so hard to store. Why does she do this? Scientists aren’t sure. Some think arctic ground squirrels must warm up in case their bodies need to fight off any germs that would make them sick.

  根据短文内容，完成下面的任务。

1. 根据上下文，画线单词hibernating的汉语意思是。

2. 用temperature写出画线句子的同义句。

3. The underlined word “changes” in paragraph three comes from his body's and.

4. 从下面A - D四个选项中为每一段选择恰当的主旨句，其中有一项多余。

   ① ② ③

   A. Colder Than Ice   B. Not Really Sleeping   C. Store food   D. Staying Well

Answer 1

  在加拿大北部，冬天是漫长而寒冷的，植物无法生长，所 以没有树叶或草为北极松鼠提供食物，因此这些小家伙选择 “冬眠”抵抗严寒。靠着体内储存的能量，以它们特有的方 式安全地度过漫长的冬季。

1. 冬眠 。根据前一句中的goes to “sleep”，再联系全文和我 们的常识 可猜测hibernating意为“冬眠”。

2. The ground squirrel's body usually has the same temperature as yours.

画线句子意为“北极松鼠的体温与你的一样温暖”。as. .. as可以与the same as替换， 都意为“与……一样”。

3. temperature;heart;breath 

仔细阅读本段，可知北极松鼠冬眠时，体温、心跳和呼吸都发生了变化。

4. ①B 根据第二段主旨句 Only she won’t really be sleeping 可知答案选B.

② A 由第二段主旨句 “ When she hibernates her body becomes colder than ice. ”可知答案选 A.

③ D第四段主要介绍了北极松鼠用温暖身体来战胜细 菌，保持身体健康，故答案选D.
