Irish Dolphins May Have a Unique Dialect
Irish scientists monitoring dolphins living in a river estuary in the southwest of the country 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 vocalizations collected on a computer in a cow shed near the River Shannon.
As part of a research project, student Ronan Hickey digitized and analyzed a total of 1,882 whistles from the Irish dolphins and those from the Welsh dolphins on a computer and separated them into six fundamental whistle types and 32 different categories. Of the categories, he found most were used by both sets of dolphins---but eight were only heard from the Irish dolphins.
“We are building up a catalogue of the different whistle types they use and trying to associate them with behavior like foraging, resting, socializing and the communications of groups with calve,” project leader Simon Berrow said. “Essentially we are building up what is like a dictionary of words they use or sounds they make.”
Berrow, a marine biologist, said the dolphins’ clicks are used to find their way around and located prey. The whistles are communications. “They do a whole range of other sounds like barks, groans and kind of gunshot,” he said. “The gunshot is an intense pulse of sound. Sperm whales use it to stun their prey.”
“When I first heard it I was surprised as I thought sperm whales were the only species who used it. We can speculate the dolphins are using 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 generations and they may even have been resident there as far back as the 6th century.
They are regularly seen by passengers on the Shannon ferry and an estimated 25,000 tourists every year take special sightseeing tours on local boasts to visit them.

1.C本題所說的意思是寬吻海豚與抹香鯨進食習慣上大相徑庭，這一點令科學家很感興趣。這種表達在文章中無法找到。
2.B題干的意思為：Ronan Hickey分析了愛爾蘭海豚發出的近2000總不同的方言。這句話與短文中敘述的意思不符。第三段第一句話這樣表述：Ronan Hickey分析了愛爾蘭海豚和威爾士海豚(不僅是愛爾蘭海豚)發出的近2000種不同的'嘯聲(不是方言)。
3.A題干表達的意思與文章第三段第二句的內容相符。32種嘯聲中有8種是愛爾蘭海豚獨有的。
4 A文章第四段第一句說科學家正設法將嘯聲與海豚的行為特性聯系起來，其中也包括成年海豚與小海豚之間的聯絡這一行為。與原文相符。
5.C題干的意思是：鯨魚能發出比海豚更強烈的超聲波去殺死獵物。但文章并沒有表達出這個意思。
6.B文章第七段提出，早在公元6世紀海豚就在香農河河口繁衍生息，而沒有說早在公元6世紀漁民開始在香農河河口養殖海豚;因此，題干與文章意思不符。
7.A題干表述的意思與最后一段的意思相符。文章說大約每年有25000名游客專程到此乘坐當地的小船觀看海豚。
