阅读短文,从每题所给的 A、B、C、D 四个选项中,选出最佳选项。
A
In the sandy Sahara and elsewhere in North Africa lives the smallest fox with the largest ears. This animal is the fennec fox.
Fennec foxes have ears that are about 15 centimetres. That’s big for an animal that weighs less than two kilogrammes. Their ears help give out body heat. And, as you may have guessed, they also have great hearing.
It’s also interesting to think about the hair of fennec foxes. Why would a fox that lives in the desert need a thick, fur coat? Actually, the desert isn’t always warm. In the nighttime, the desert can be downright cold! Fennec foxes’ fur keeps them warm during those chilly desert nights. They also have long bushy tails that they use as blankets. And the hair on their feet protects them from the hot sand in the daytime. Fennec foxes live in small communities of dens (洞穴). They spend most of the day sleeping in their dens, out of the hot sun. Then, when night comes, they come out in search of food. In addition to their great hearing, fennecs also use their great sense of smell and big eyes to track down dinner.
Like other foxes, fennecs are omnivores (杂食动物). This means they eat both meat and plants. Some of their favourite foods include birds, eggs, insects, snails, fruit and leaves.
The female fennec fox gives birth to one to five babies at a time. The average life span (跨度) of a fennec fox is 10 to 12 years.
1. What is the unique function of the big ears of the fennec fox?
A. They can help give out body heat.
B. They can heat the body.
C. They help them lose weight.

(A)
2. What does the underlined word “chilly” in paragraph 3 probably mean?
A. Very warm.

答案： 1. A 细节理解题。由第二段第三句可知，耳廓狐的大耳朵能够帮助散热，因此选A。
2. B 词义猜测题。由画线单词上一句可知，沙漠在夜晚非常冷，chilly应该表达“寒冷的”的意思，rather cold意为“相当寒冷”，符合语境，因此选B。
