Ronan Hickey analyzed almost 2000 different dialects of the bottle-nose dolphins.
A．Right
B．Wrong
C．Not mentioned
相似考题
参考答案和解析
正确答案：B
解析：问题中的关键词组是of the bottle-nose dolphins。利用问题句中的特征词Ronan Hickey(人名)和2000 different(不同的)dialects为答案线索，对应原文第三段第一句，…student Ronan Hiekey digitised and analyzed a total of 1,882 whistles from the Irish dolphins and those from the welsh dolphins…可知Ronan Hickey不是分析宽吻海豚，而是爱尔兰海豚和威尔士海豚发出的近2000种不同的啸声(不是方言)。所以，本题选项B是答案。

Chinese Dialects（方言）
The enormous differences in Chinese dialects have been a continuing problem ever since China became an empire in 221 B.C.,and it is one big reason why the country has remained impoverished （贫穷）.Of the 600 million people,all but a very small number speak Chinese. But the dialects vary so widely that the speech of Peking,for example,is as different from the speech of Canton as English is from German.
There is,to be sure,only one written language for all China,but it bears no phonetic（语音的）relationship to any of the spoken dialects.Moreover,it has so many symbols that only a tiny portion of the population has ever mastered it.
As a result,most Chinese have been isolated for centuries from a free flow of ideas and from the economic progress that such a flow produces.Many dynasties tried with little success to break down the wall. After recognizing the importance of having a literate people for working in a technological world and for developing an effective propaganda（宣传）machine,the present government is putting everything it has into tackling the language problem. But the obstacles are so formidable（难以应付的）that the results cannot yet be predicted.
At the heart of the problem is the dialects.The dialects prevented the evolution of a single written language based on phonetics.Instead,the Chinese were forced to develop a system that has no relation to sound,and they have clung to it for more than 3,000 years.When this system is applied to a whole language,it results in an overwhelming number of symbols.
There are about 50,000 entries in a Chinese dictionary not counting the compounds（复合词）. In order to be literate,a Chinese must learn 6,000;to be moderately educated,12,000.An English-speaking child,having to conquer only a twenty-six-letter alphabet,has usually learned to read by the time he begins the third grade.A Chinese child needs at least five more years of elementary learning;in the seventh grade,he can barely read a Chinese newspaper.Paragraph 3______

B:Difficulties in Learning Chinese
C:Features of Chinese Dialects
D:Differences in Chinese Dialects
E:Dialects as Heart of the Problem
F: Ways of the Government to Tackle the Problem答案：A解析：本题考查的是对所读材料大意与主旨的掌握。本段主要讲中国方言之间有巨大的差异，第一句话就是本段的主题句。另外，该段还举出北京话与广东话之间差别的例子。故选D。
本题考查的是对所读材料大意与主旨的掌握以及抽象概括能力。本段谈到语言问题阻碍了思想与经济的交流，历朝政府都想解决这一问题。当前政府已经认识到解决语言问题的重要性，投入全力来对付。所以，该段的主题是tackling the language problem,.tackling的意思就是选项A的dealing with，故选A。
本题考查的是对所读材料大意与主旨的掌握。本段讲到关键问题是方言，方言使单一的书面语无法同读音相联系，中国人只好创立了一套与发音无关的系统，这造成了繁多的字符。可见问题的核心是方言。故选E。
本题考查的同样是对所读材料大意与主旨的掌握。本段讲汉字繁多，难于掌握，对比了中国孩子与讲英语的孩子学习阅读的进度，反衬出汉语之难学。故选B。
本题考查的是对文章的主旨与细节的了解。本题答案的依据在第一段的第一句话。该句说这个国家（中国）之所以长期贫穷，一个重要原因是中国各地方言差别太大 ( the enormous differences in Chinese dialects)。故选C。
本题考查的是对文章的主旨与细节的了解。本题答案的依据在第四段的第二句。在作者看来，方言的繁多使中国不能发展出一套以音节为基础的单一书面语，故选A。
本题考查的是对文章的主旨与细节的了解。本题答案的依据在第四段的二、三、四句。正因为中国不能发展出一套以音节为基础的单一书面语，语言系统与发音无关，这就势必造成大量字符的出现。最后一句话中的results in就是“导致”的意思。倒数第二句则说明了原因。故选D。

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.The difference in eating habits between the bottle-nose dolphins arid the sperm wha1c, intcrcotcd the SDWFscientists.

The enormous differences in Chinese dialects have been a continuing problem ever since China became an empire in 221 B.C.,and it is one big reason why the country has remained impoverished （贫穷）.Of the 600 million people,all but a very small number speak Chinese. But the dialects vary so widely that the speech of Peking,for example,is as different from the speech of Canton as English is from German.

At the heart of the problem is the dialects.The dialects prevented the evolution of a single written language based on phonetics.Instead,the Chinese were forced to develop a system that has no relation to sound,and they have clung to it for more than 3,000 years.When this system is applied to a whole language,it results in an overwhelming number of symbols.
There are about 50,000 entries in a Chinese dictionary not counting the compounds（复合词）. In order to be literate,a Chinese must learn 6,000;to be moderately educated,12,000.An English-speaking child,having to conquer only a twenty-six-letter alphabet,has usually learned to read by the time he begins the third grade.A Chinese child needs at least five more years of elementary learning;in the seventh grade,he can barely read a Chinese newspaper.The result of the enormous differences in Chinese dialects,as far as the author is concerned,is that______.
A:China failed to develop a single written language based on phonetics
B:a Chinese child is supposed to learn much more words than his English speaking counterpart
C:enormous differences in Chinese dialects
D:the Chinese language system has no relation to sound
E:educate more people to learn the same language
F: there is only a small part of the population who understand the large number of symbols答案：A解析：本题考查的是对所读材料大意与主旨的掌握。本段主要讲中国方言之间有巨大的差异，第一句话就是本段的主题句。另外，该段还举出北京话与广东话之间差别的例子。故选D。
本题考查的是对所读材料大意与主旨的掌握以及抽象概括能力。本段谈到语言问题阻碍了思想与经济的交流，历朝政府都想解决这一问题。当前政府已经认识到解决语言问题的重要性，投入全力来对付。所以，该段的主题是tackling the language problem,.tackling的意思就是选项A的dealing with，故选A。
本题考查的是对所读材料大意与主旨的掌握。本段讲到关键问题是方言，方言使单一的书面语无法同读音相联系，中国人只好创立了一套与发音无关的系统，这造成了繁多的字符。可见问题的核心是方言。故选E。
本题考查的同样是对所读材料大意与主旨的掌握。本段讲汉字繁多，难于掌握，对比了中国孩子与讲英语的孩子学习阅读的进度，反衬出汉语之难学。故选B。
本题考查的是对文章的主旨与细节的了解。本题答案的依据在第一段的第一句话。该句说这个国家（中国）之所以长期贫穷，一个重要原因是中国各地方言差别太大 ( the enormous differences in Chinese dialects)。故选C。
本题考查的是对文章的主旨与细节的了解。本题答案的依据在第四段的第二句。在作者看来，方言的繁多使中国不能发展出一套以音节为基础的单一书面语，故选A。
本题考查的是对文章的主旨与细节的了解。本题答案的依据在第四段的二、三、四句。正因为中国不能发展出一套以音节为基础的单一书面语，语言系统与发音无关，这就势必造成大量字符的出现。最后一句话中的results in就是“导致”的意思。倒数第二句则说明了原因。故选D。
本题考查的是对文章的主旨与细节的了解以及抽象概括能力。本题与上面的第26题有联系，答案的依据在最后一段。该段举出中外儿童学习阅读的进度对比的例子，所给数据显示，中国孩子在学习母语时要比外国孩子掌握更多的生词。这就是作者认为的二者的不同之处。故选B。 -
