科學(xué)家們用數(shù)年時(shí)間仔細(xì)聆聽了我們的類人猿近親 —— 紅毛猩猩與同伴交流時(shí)發(fā)出的尖叫聲，該研究為解釋人類語言的形成過程提供了線索。英國杜倫大學(xué)的阿德里亞諾·拉梅哈（ Adriano Reis e Lameira ）博士錄制并分析了這些動(dòng)物發(fā)出的近  5000 段“吻叫”，它們雙唇緊閉的嘴型很像人類語言中輔音的發(fā)聲方式。他還發(fā)現(xiàn)紅毛猩猩會(huì)通過組合音節(jié)向同伴傳達(dá)不同的信息。請(qǐng)聽 Victoria Gill 的報(bào)道。

The researchers spent thousands of hours listening to these communicative ‘kiss squeaks’, analysing almost 5,000 squeaks from 48 individual orangutans.

They homed in on these sounds in particular because they’re formed in a similar way to our consonants. Just like our /t/ and /p/ sounds, kiss squeaks are made using the lips and tongue to control air flow rather than using the voice in calling out.

With this painstaking listening exercise and observing the animals as they communicated, the team revealed that orangutans combine multiple kiss squeaks in different orders, apparently conveying different messages. The scientists say that’s an early glimpse of how our ancestors began to combine consonants and vowels, and that these could be the purse-lipped building blocks of our very earliest multi-syllable words.

答案

1. How many individual orangutans were involved in the study?
There were 48 individual orangutans involved in the study.

2. Why did the researchers put focus on the 'kiss squeaks' in particular?
The researchers put focus on the 'kiss squeaks' in particular because they're formed in a similar way to our consonants.

3. True or false? Kiss squeaks are made using the voice.
False. Just like our /t/ and /p/ sounds, kiss squeaks are made using the lips and tongue to control air flow rather than using the voice in calling out.

4. Which word in the text means 'the early forms of species from which others have evolved'?
Ancestors.
