Dolphins are universally regarded as some of the cleverest creatures in the world. In captivity ( 圈养), they can be trained to complete complex tasks such as jumping through hoops and somersaulting through the air.

But their intelligence doesn’t stop there. In a recent study of cetaceans (鲸目动物)--a group of animals that includes dolphins and whales--researchers created a list of intelligent behaviors observed in 90 different cetacean species, reported the Guardian. For example, the smartest cetaceans hunt in groups, share knowledge through mimicry (模仿) and even care for each other's children. Some even consider their behavior to be human-like.

“There is the saying that ‘it takes a village to raise a child’ seems to be true for both whales and humans,”

Michael Muthukrishna of the London School of Economics, co-author of the study, told the Guardian.

However, cetaceans don’t just use their brain power for survival. The study suggests that dolphins might even gossip. That's because some species greet each other with specific whistles, just as humans greet each other by name, the Guardian reported. Sometimes, a group of dolphins whistles the “name” of a dolphin that isn't there. Could they be speaking about their “friend” behind its back?

For the researchers, dolphin small talk is a big deal. As they found that the most social cetaceans also have the largest brains, they argue that cetacean intelligence developed to meet the demands of complex social groups.

Known as the “cultural brain hypothesis (假设),” it had only been used to explain the intelligence of humans and other primates (灵长目动物). The new study aimed to find a common pathway for the evolution of intelligence among biologically different species.

“It is interesting to think that whale and human brains are different in their structure but have brought us to the same patterns in behavior, ” Luke Rendell, a biologist at the University of St Andrews, told the Guardian.

Indeed, we still have a lot to learn about our intelligent ocean-dwelling neighbors. “We don’ t have to look at other planets to look for aliens,” Muthukrishna told the Guardian, “because we know that underwater there are these amazing species with so many parallels to us in their complex behaviors.”

1.The recent study was intended to ______.

A.learn more about intelligent creatures of the sea

B.explain the intelligence of humans and cetaceans

C.create a list of intelligent behaviors of different cetacean species

D.see whether the intelligence of different species evolved in the same way

A.villagers have the responsibility　 to raise any child in the village

B.like human beings, whales even help raise each other’s babies

C.cetaceans have social behaviors very similar to human beings

D.it is not easy for one villager to take care of his or her own child

3.It can be inferred from the passage that ______.

A.it is unnecessary to look for aliens and do research into them

B.some cetaceans have the same intelligence as human beings

C.both dolphins and whales greet each other with specific whistles

D.both dolphins and whales have a lot in common with humans in behaviors

There are around 6,000 living languages in the world- and at least half of these are in danger. In every part of the world, languages are disappearing. In fact, one scientist has said that languages are in more danger of extinction than binds or mammals. Professor Steve Sutherland of the University of East Anglia says that in the past 500 years 4.5 percent of languages have died out- compared with 1.3 percent of birds, and 1.9% percent of mammals

Languages come and go, and thousands have done exactly that without leaving any trace. Only a very few- Basque, Greek and Latin among them- have lasted more than 2,000 years. But it seems that the pace of their disappearance is becoming quicker

The Ethnologue, a database of all the languages spoken in the world, states that 417 languages are spoken by so few people that they are in the final stages of becoming extinct. If very few people speak a language, it will probably die out.

Languages may be lost through migration (迁移), as people move from small towns to city centers, or when environments are destroyed by the search for oil or wood. Natural disasters can also devastate populations, and along with them, their language. Governments also play a role in the extinction of languages. The need to establish “official languages”, for a country to educate its children and carry out its business, had a disastrous effect on many small languages.

What is lost if a language is lost? Some people argue that languages die as the human race develops. Obviously there could be great benefits if everyone in the world spoke the same language- some industries already reflect this, with English essential for pilots and air traffic controllers. But there are more important things than convenience.As languages are lost, whole ways of life and knowledge may be lost along with them.

To put it simply, language expresses something about identity, about our place in the world. Ani Rauhihi, a Maori teacher in New Zealand's North Island, sums it up: “If you grow up speaking our language, you won 't know who you are.”

1.The figures mentioned in the first paragraph suggest that__________.

A.most languages have died out completely

B.languages are in great danger of extinction

C.animals are disappearing faster than languages

D.languages are disappearing slower than before

2.The underlined word "devastate"can best be replaced by“__________”

A.increase B.control

C.destroy D.improve

3.If a language is lost, __________

A.there will be great trouble

B.there is no need to worry about it

C.its culture and knowledge will also be lost

D.people will be able to communicate with others conveniently

4.What can we infer from the last paragraph?

A.Languages reflect our identity.

B.People will speak the same language one day

C.Fewer people will remember their own languages.

D.Ani Rauhihi cares less about languages dying out
