Irish Dolphins may have a unique dialect

Irish scientists monitoring dolphins living in a river estuary in the southwest of the c,ountry believe they may have developed a unique dialect to communicate with each other．

The Shannon Dolphin and Wildlife Foundation（SDWF）has been studying a group of up to 120 bottle—nose dolphins in the River Shannon using vocalisations collected on a computer in a cowshed near the River Shannon．

As part of a research project．student Ronan Hickey digitised and analysed a total of 1，882 whisties from the Irish dolphins and those from the Welsh dolphins on a computer and separated them into six fundamental whistle types and 32 different eategories．0f the categories，he found most6 were used by both sets of dolphins一but eight were only heard from the Irish dolphins．

“We are building up a catalogue 0f the different whistle types they use and trying to associate them with behaviour like foraging，resting，socialising and the communications of groups with calves”project leader Simon Below said．“Essentially we are building up what is like a dictionary 0f words they use 0r sounds they make．”

Below，a nlan’ne biologist，said the dolphins’clicks are used t0 find their way around and locate prey．The whistles are communications．“They d0 a whole range 0f other sounds like barks，groans and a kind 0f gunshot．”he said．“The gunshot is an intense pulse of sound．Sperm whales use it t0 stun their prey．”

“When I first heard it 1 was surprised as I thought sperm whales were the only species who used it．We can speculate the dolphins are usin’g it for the same reason as the sperm whales，”Berrow said．

References in local legend indicate there have been dolphins in the Shannon estuary for generatl’ons and they may even have been resident there as far back as the 6th century9．

They are regularly seen by passengers 0n the Shannon ferry and an estimated 25，000 tourists every year take special sightseeing tours on local boats t0 visit them．

C．Not mentioned

This type of learning, however, is called conditioning. The animal simply learns that when

it performs a particular behavior, it gets a reward, usually a fish. Many animals, including rats, birds, and even invertebrates, can be conditioned to perform. tricks. We certainly dont think of these animals as our mental rivals. Unlike most other animals, however, dolphins quickly learn by observations and may spontaneously imitate human activities. One tame dolphin watched a diver cleaning an underwater viewing window, seized a feather in its beak, and began imitating the diver—complete with sound effects! Dolphins have also been seen imitating seals, turtles, and even water-skiers.

The word "tempted" in the passage is closest in meaning to

A．conditioned

B．reluctant

C．inclined

D．invited

第9题

听力原文：W: Wasn't that a terrific lecture on dolphins？ I didn't know that dolphins travel

ed in such large groups, or were able to communicate with other members of their group with those whistle-like sounds.

M: And they also use clicks as a sort of sonar.

W: I really couldn't understand that part of the lecture. You could？

M: Yes, the dolphins use clicks to identify objects in the water; they can even identify tiny objects more than 100 meters away using these clicks. Scientists believe that a dolphin may even have a sonar-like image in its brain of a distant object so that it can identify the object long before the dolphin can actually see the object.

W: So the dolphins use these clicks mostly to identify objects in the water？

M: I think so, and they have considerably more ability to do this than humans do.

W: It is hard to believe that, in addition to these sonar clicks, dolphins are actually learning some human language.

M: Yes, I believe that the lecture said that some dolphins had already learned around fifty human commands, and that those dolphins were able to understand not only individual words but words clustered together in sentences!

W: Dolphins must certainly be amazing animals to do all of that.

M: I'm sure they are, and we're only just beginning to find out how intelligent they are.

Where did the woman learn about dolphins？

A．In a book..

B．From a television program.

C．During a trip that she took..

D．From a lecture.

Instead of "intelligence," some people prefer to speak of "awareness." In any case, cetace

ans probably have a very different awareness and perception of their environment than do humans. Maybe one day we will come to understand cetaceans on their terms instead of ours, and perhaps we will discover a mental sophistication rivaling our own.
