研真题链接高考
(2022新高考全国Ⅰ卷,阅读D)——一个关于唇齿音演化的成果
Human speech contains more than 2,000 different sounds,from the common “m” and “a” to the rare clicks of some southern African languages.But why are certain sounds more common than others A ground-breaking,five-year study shows that diet-related changes in human bite led to new speech sounds that are now found in half the world's languages.
More than 30 years ago,the scholar Charles Hockett noted that speech sounds called labiodentals,such as “f” and “v”,were more common in the languages of societies that ate softer foods.Now a team of researchers led by Dami n Blasi at the University of Zurich,Switzerland,has found how and why this trend arose.
They discovered that the upper and lower front teeth of ancient human adults were aligned (对齐),making it hard to produce labiodentals,which are formed by
touching the lower lip to the upper teeth.Later,our jaws changed to an overbite structure (结构),making it easier to produce such sounds.
The team showed that this change in bite was connected with the development of agriculture in the Neolithic period.Food became easier to chew at this point.The jawbone didn't have to do as much work and so didn't grow to be so large.
Analyses of a language database also confirmed that there was a global change in the sound of world languages after the Neolithic age,with the use of “f” and “v” increasing remarkably during the last few thousand years.These sounds are still not found in the languages of many hunter-gatherer people today.
This research overturns the popular view that all human speech sounds were present when human beings evolved around 300,000 years ago.“The set of speech sounds we use has not necessarily remained stable since the appearance of human beings,but rather the huge variety of speech sounds that we find today is the product of a complex interplay of things like biological change and cultural evolution,” said Steven Moran,a member of the research team.
一、理清脉络
二、真题再做
32.Which aspect of the human speech sound does Dami n Blasi's research focus on
A.Its variety. B.Its distribution. C.Its quantity. D.Its development.
D　
细节理解题。根据第二段的“Now a team of researchers led by Damin Blasi at the University of Zurich,Switzerland,has found how and why this trend arose.”可知,Damin Blasi的研究关注的是人类语言的发展。故选D项。
33.Why was it difficult for ancient human adults to produce labiodentals
A.They had fewer upper teeth than lower teeth.
B.They could not open and close their lips easily.
C.Their jaws were not conveniently structured.
D.Their lower front teeth were not large enough.
C
推理判断题。根据第三段可知,古代成年人的上下门牙排列整齐,很难产生唇齿音,唇齿音是通过下唇接触上牙形成的。后来,我们的下巴变成了覆颌结构,更容易发出这样的声音。由此可知,古代成年人难以发出唇齿音的原因是覆颌结构不好。故选C项。
34.What is paragraph 5 mainly about
A.Supporting evidence for the research results.
B.Potential application of the research findings.
C.A further explanation of the research methods.
D.A reasonable doubt about the research process.
A
段落大意题。第五段提到,一个语言数据库的分析也证实,新石器时代之后,世界语言的发音发生了全球性的变化,在过去的几千年里,“ f ”和“ v ”的使用显著增加。这些音在今天许多狩猎采集者的语言中仍然找不到。由此可知,第五段是为上文提到的研究发现进一步提供证据。故选A项。
35.What does Steven Moran say about the set of human speech sounds
A.It is key to effective communication.
B.It contributes much to cultural diversity.
C.It is a complex and dynamic system.
D.It drives the evolution of human beings.
细节理解题。根据最后一段Steven Moran说的话可知,自人类出现以来,我们所使用的语音并不一定一直保持稳定,而是我们今天发现的各种语音是生物变化和文化进化等复杂因素相互作用的产物。由此可知,语言是一个复杂的动态系统。故选C项。
C
