Squirrels often communicate with whistles, chirps and chucks, which sound like the word “chuck”. Whistles and chirps are like the sounds that many birds make.Now scientists have translated some of their squirrel-speak.
Hare, a professor of zoology at the University of Maniloha in Winnipeg, and his team managed to record squirrels' alarm calls.The researchers studied the sounds and then played them back to 60 wild squirrels, which the scientists approached individually with a video recorder to capture(抓拍)their reponses.Some squirrels lifted their heads up and became.Alert(警惕的).Creatures that were more frightened simply ran for their lives and dived into caves.
"In effect then, whistles that mix with chucks say 'there's an enemy of average threat that's here', and whistles without chucks say 'there's an enemy of seemingly average threat around here somewhere', while pure chirps say, 'I'm hiding here because there's an immediate danger.' " Hare told.Discovery News.
Hare and some other researchers believe such sounds arc part of an advanced language that develops just as all other communication systems.
Although squirrels risk their lives when they call out to warn others of threats, other squirrels might admire this behaviour, thus increasingly the caller’s social status, like humans who look up to heroes. Hare added that other animals, such as birds, probably understand at least some squirrel language, since they also may benefit from the alarm calls.
In fact, another Canadian study found that deep-voiced, black-capped chickadees have their own language too.According to certain research, there are a lot of tidings in chickadees' calls, such as directing fellows' activities, keeping in contact between mates, and raising alarms.
While chickadees and other birds are often welcomed into gardens by homeowners, squirrels are frequently viewed as pests(害兽). Hare wishes a greater understanding of the complex social lives and communication systems of squirrels will provide “hope that humans will gain a greater appreciation and stop doing harm to these animals”.

解析试题分析:文章向我们讲述了Hare以及他带领的团队对松鼠们所使用的语言的研究。
【小题1】A 主旨大意题。纵观全文可以看出,文章向我们讲述了Hare以及他带领的团队对松鼠们所使用的语言的研究.
【小题2】B细节理解题。由文章中的“while pure chirps say, 'I'm hiding here because there's an immediate danger”可以看出,B项正确。
【小题3】C词义推测题。下文such as 后里列举的“directing fellows' activities, keeping in contact between mates, and raising alarms”都是是不同的信息,由此可以看出,该词和message同义。
【小题4】B 推理判断题。从文章的第二段中“…Some squirrels lifted their heads up and became.Alert(警惕的).Creatures that were more frightened simply ran for their lives and dived into caves.”可以看出,松鼠们对于“the recorded alarm calls”反应很忙敏感,也就是说他们能理解。

Some mammals migrate(迁徒). One of these is the caribou(驯鹿). They travel to the tundra(苔原)every summer to eat the rich grasses that grow there. When the weather becomes cooler, they migrate to the warmer forests and spend the winter there. Another mammal that migrates is the humpback whale. They spend the winter in Hawaii, and the summer in the Arctic(北极的)waters. They travel to the Arctic to eat millions of small shrimp(虾).
Anther habit that some animals have to survive the cold winter is called hibernation. Animals that hibernate, rest or sleep during the winter. While they are hibernating, their bodies use up the fat layer that they have put on by eating large amounts of food during the summer. Some animals that hibernate in the Arctic are small animals called lemmings(旅鼠), squirrels(松鼠)and bears.
There are two habit adaptations that animals in the Arctic have all year round. These are called herding and pack life. Caribou are example of animals that live in herds. A herd is a group of animals that lives together for most, or all of their lives. A herd of caribou can have a thousand or more animals in it. They live in herds for protection. It is easier for caribou to protect themselves when they are together than it is when they are alone. This is because the meat-eaters hunt in packs.
A pack is a small group of animals that lives together. It is usually controlled by a head male and a female. All the members of the pack must obey them. Packs have a very definite social structure. Each animal in a pack has a different position, or importance. Animals in a pack are usually meat-eaters. They live together for protection and hunting purposes.
