劍橋雅思真題15閱讀解析：Silbo Gomero

You should spend about 20 minutes on Questions 14-26, which are based on Reading Passage 2 below.

Silbo Gomero 一 the whistle 'language' of the Canary Islands

La Gomera is one of the Canary Islands situated in the Atlantic Ocean off the northwest coast of Africa. This small volcanic island is mountainous, with steep rocky slopes and deep, wooded ravines, rising to 1,487 metres at its highest peak. It is also home to the best known of the world's whistle 'languages', a means of transmitting information over long distances which is perfectly adapted to the extreme terrain of the island.

This 'language', known as 'Silbo' or 'Silbo Gomero' - from the Spanish word for 'whistle'- is now shedding light on the language-processing abilities of the human brain, according to scientists. Researchers say that Silbo activates parts of the brain normally associated with spoken language, suggesting that the brain is remarkably flexible in its ability to interpret sounds as language.

'Science has developed the idea of brain areas that are dedicated to language, and we are starting to understand the scope of signals that can be recognised as language,' says David Corina, co-author of a recent study and associate professor of psychology at the University of Washington in Seattle.

Silbo is a substitute for Spanish, with individual words recoded into whistles which have high- and low-frequency tones. A whistler - or silbador - puts a finger in his or her mouth to increase the whistle's pitch, while the other hand can be cupped to adjust the direction of the sound. 'There is much more ambiguity in the whistled signal than in the spoken signal/ explains lead researcher Manuel Carreiras, psychology professor at the University of La Laguna on the Canary island of Tenerife. Because whistled 'words' can be hard to distinguish, silbadores rely on repetition, as well as awareness of context, to make themselves understood.

The silbadores of Gomera are traditionally shepherds and other isolated mountain folk, and their novel means of staying in touch allows them to communicate over distances of up to 10 kilometres. Carreiras explains that silbadores are able to pass a surprising amount of information via their whistles. 4In daily life they use whistles to communicate short commands, but any Spanish sentence could be whistled.5 Silbo has proved particularly useful when fires have occurred on the island and rapid communication across large areas has been vital.

The study team used neuroimaging equipment to contrast the brain activity of silbadores while listening to whistled and spoken Spanish. Results showed the left temporal lobe of the brain, which is usually associated with spoken language, was engaged during the processing of Silbo. The researchers found that other key regions in the brain's frontal lobe also responded to the whistles, including those activated in response to sign language among deaf people. When the experiments were repeated with non-whistlers, however, activation was observed in all areas of the brain.

'Our results provide more evidence about the flexibility of human capacity for language in a variety of forms' Corina says. 'These data suggest that left-hemisphere language regions are uniquely adapted for communicative purposes, independent of the modality of signal. The non- Silbo speakers were not recognising Silbo as a language. They had nothing to grab onto, so multiple areas of their brains were activated?

Carreiras says the origins of Silbo Gomero remain obscure, but that indigenous Canary Islanders, who were of North African origin, already had a whistled language when Spain conquered the volcanic islands in the 15th century. Whistled languages survive today in Papua New Guinea, Mexico, Vietnam, Guyana, China, Nepal, Senegal, and a few mountainous pockets in southern Europe. There are thought to be as many as 70 whistled languages still in use, though only 12 have been described and studied scientifically. This form of communication is an adaptation found among cultures where people are often isolated from each other, according to Julien Meyer, a researcher at the Institute of Human Sciences in Lyon, France. 'They are mostly used in mountains or dense forests, ' he says. 'Whistled languages are quite clearly defined and represent an original adaptation of the spoken language for the needs of isolated human groups?

But with modern communication technology now widely available, researchers say whistled languages like Silbo are threatened with extinction. With dwindling numbers of Gomera islanders still fluent in the language, Canaries' authorities are taking steps to try to ensure its survival. Since 1999, Silbo Gomero has been taught in all of the island's elementary schools. In addition, locals are seeking assistance from the United Nations Educational, Scientific and Cultural Organization (UNESCO). {The local authorities are trying to get an award from the organisation to declare [Silbo Gomero] as something that should be preserved for humanity,' Carreiras adds.

答案解析

Question 14

答案：NOT GIVEN

關(guān)鍵詞：La Gomera, Canary Islands

解題思路：文中第一句提到La Gomera是Canary Islands中的一座。第二句提到這個小火山島是多山的。但是并不能據(jù)此判斷這里是山最多的地方，屬于典型的證據(jù)不充分型論斷。

Question 15

答案：FALSE

關(guān)鍵詞：short and simple messages

解題思路：不建議用Silbo作定位詞，因為該詞在全文出現(xiàn)很多次。本題可以用short and simple messages定位。考點是絕對化詞匯only。文中對應(yīng)句說：Carreiras解釋說，哨語者能夠通過他們的口哨聲傳遞數(shù)量驚人的信息。在日常生活中，他們用口哨聲來傳達(dá)簡短的命令，但任何西班牙語句子都可以用口哨聲來傳達(dá)。說明Silbo并不是只適合短的、簡單的信息。

Question 16

答案：TRUE

關(guān)鍵詞：brain-activity, non-whistlers

解題思路：通過brain-activity定位到第六段第一句話，但是后面一直在講哨語者的情況，直到最后一句出現(xiàn)了非哨語者。通過however的邏輯關(guān)系基本可以判斷出關(guān)于非哨語者和哨語者的研究結(jié)果是不一樣的。

Question 17

答案：FALSE

關(guān)鍵詞：Spanish, 15th century

解題思路：原文對應(yīng)句中提到：CaiTeiras說，Silbo Gomero的起源至今仍不清楚，但加那利群島的北非裔土著居民，在15世紀(jì)西班牙征服這些火山島時，就已經(jīng)掌握了一門口哨語言。題目與原文明顯矛盾。

Question 18

答案：FALSE

關(guān)鍵詞：precise data, whistle languages

解題思路：本題主要的判斷點就在于all，是否所有口哨語言都有精確數(shù)據(jù)。文中對應(yīng)句說：據(jù)認(rèn)為，目前仍在使用的口哨語言多達(dá)70種，但只有12種被科學(xué)地描述和研究過。因此可以看出不是所有口哨語言都有精確資料。
