【题目】Dolphins call out the specific names of loved ones when they become separated, a study finds.Other than humans, they are the only animals known to do this, according to the study.The big difference with dolphins is that these communications consist of whistles(鸣叫), not words.

Earlier research found that dolphins have a “signature whistle” that would be somewhat like human shouting, “Hey everybody! I’m an adult healthy male named George, and I mean you no harm.”

The new finding is that dolphins also say the names of certain other dolphins.“Animals produced copies of the same sound when they were separated from a close partner.This supports our belief that dolphins copy another animal’s signature whistle when they want to reunite with that animal,” Stephanie King, who led the study, says.

King and her colleagues collected acoustic(声音的)data from wild dolphins around Sarasota Bay, Florida, from 1984 to 2009.The researchers also studied four adult male dolphins housed at the Seas Aquarium, also in Florida.

Those males are adults that keepers named Calvin, Khyber, Malabar and Ranier, all of whom, as well as all of the wild ones, developed their own signature whistles that served as names in communication with other dolphins.

“A dolphin uses its signature whistle to broadcast its identity and announce its presence.The signature whistles allow animals to identify one another over long distances and allow animals to recognize one another and to join up with each other,” King explains.“Dolphin whistles can be heard up to 20km away, depending on water depth and whistle frequency(频率).”

The researchers said dolphins copy the signature whistles of loved ones, such as a mother, when the two are separated.These “names” are always used in positive situations, and are only directed toward loved ones.

While researchers are often unwilling to apply the word language to non-human communications, dolphins clearly have a very complex communication system.

【1】The underlined word “housed” in Paragraph 4 probably means “_________”.

A.raised B.saved C.discovered D.hunted

2Which of the following plays a part in whether dolphin whistles can be heard over a distance?

A.The dolphin’s identity.

B.The water temperature

C.The whistle frequency.

D.The dolphin’s age.

3When do dolphins copy the signature whistles of loved ones?

A.When there is a fight.

B.When their keeper comes.

C.When they are apart.

D.When they are hungry.

4Where is the passage probably taken from?

A.A magazine about scientific advances.

B.A website about various animals.

C.A report on animal acoustics.

D.An essay about the relationship between humans and animals.

A.

A group of graduates, highly established in their careers, got together to visit their old university professor. Conversation soon turned into complaints about stress in work and life.

Offering his guests coffee, the professor went to the kitchen and returned with a large pot of coffee and an assortment of cups - porcelain, plastic, glass, crystal, some plain looking, some expensive, some exquisite -- telling them to help themselves to the coffee.

When all the students had a cup of coffee in hand, the professor said: "If you noticed, all the nice looking expensive cups were taken up, leaving behind the plain and cheap ones. While it is normal for you to want only the best for yourselves, that is the source of your problems and stress.

Be assured that the cup itself adds no quality to the coffee. In most cases it is just more expensive and in some cases even hides what we drink. What all of you really wanted was coffee, not the cup, but you consciously went for the best cups. And then you began eyeing each other's cups. Now consider this: Life is the coffee; the jobs, money and position in society are the cups. They are just tools to hold and contain Life, and the type of cup we have does not define, nor change the quality of Life we live. Sometimes, by concentrating only on the cup, we fail to enjoy the coffee God has provided us."

God brews the coffee, not the cups. Enjoy your coffee!

"The happiest people don't have the best of everything. They just make the best of everything."

Live simply. Love generously. Care deeply. Speak kindly.

Leave the rest to God.
