问题共用题干 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（发声）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 theni into six fundamental
whistle types and 32 different categories.Of the categories,he found most were used by both sets of dol-
phins一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（觅食）,resting, socializing and the communications of grown.ups with calves (幼
仔）,"project leader Simon Berrow said.“Essentially we are building up what is like a dictionary of words
they use or sounds they mnake."
Berrow,a marine biologist,said the dolphins'clicks are used to find their way around and locate prey.
The whistles are communications."They do a whole range 0f other sounds like barks．groans and a kind of
gunshot," he said. "The gunshot is an intense pulse（脉冲）of sound. Sperm whales use it to stun（击昏）
their prey.”
"When I first heard it I was surprised as I thought sperm whales were the onlyh 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 residents 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 boats to visit them.

选项 Sperm whales were the only species that can use pulses of sound to stun their prey. A:Right B:Wrong C:Not mentioned

答案 B

解析利用题干句的特征词sperm whales作为线索，发现文中第5、6两段与其相关。但是相关的语句中都没有涉及题干句中关于饮食习惯差异的内容，因此判断题干句的内容在文章中没有被提到。
利用题干句的特征词32 categorie、和eight作为线索，找到相关句“…32 different catego-ries.Of the categories,he found most were used by both sets of dolphins一but eight were only heard from the Irish dolphins.”这与题干句意思一致，故选A。
利用题干句的特征词communicate、 adult和baby为线索，找到相关句“…of the different whistle types…to aggociate them with behavior like…and the communicationg of grown-ups with calves"，这是说科学家正在设法将哨声与海豚的行为联系起来，如成年海豚用它来与小海豚进行沟通。题干句的意思与原文的意思相符，所以答案是A。
利用题干句的特征词Simon Berrow和dictionary为线索，找到相关句“…Simon Berrow said,'…we are building up what jg like a dictionary of wordc they uce or g ound、 they make'”,；坟与题干句意思完全吻合，所以选A。
利用题干句的特征词pulses of sound为线索，查找原文，找到“The gunshot is an intense pulse（脉冲）of sound.Sperm whales use it to stun their prey.”。但是是不是只有抹香鲸会用脉冲呢？继续看下文，发现下一段说海豚也会用，所以题干句的内容不正确：
利用6th century这个特征词在原文中可以找到相关信息，在倒数第2段，意为“……早在公元6世纪，海豚就在香农河河口繁衍生息”，而不是“被渔民养殖”，所以答案是B
利用特征词25,000为线索，查找原文，找到“…an estimated 25 , 000 tourists every year take special sightseeing tours on local boats to visit them."；还需要确定该句中的they是否指代 Irish dolphins，借助前句内容知道they指代Shannon河口的海豚，由文章开头两段可知River Shannon是爱尔兰的河流，所以答案是A。第3部分：概括大意与完成句子
