(2022新高考全国Ⅰ卷,阅读理解D)——语言Human speech cntains mre than 2,000 different sunds,frm the cmmn “m” and “a” t the rare clicks f sme suthern African languages.But why are certain sunds mre cmmn than thers?A grund-breaking,five-year study shws that diet-related changes in human bite led t new speech sunds that are nw fund in half the wrld's languages.Mre than 30 years ag,the schlar Charles Hckett nted that speech sunds called labidentals,such as “f” and “v”,were mre cmmn in the languages f scieties that ate sfter fds.Nw a team f researchers led by Damián Blasi at the University f Zurich,Switzerland,has fund hw and why this trend arse.
They discvered that the upper and lwer frnt teeth f ancient human adults were aligned (对齐),making it hard t prduce labidentals,which are frmed by tuching the lwer lip t the upper teeth.Later,ur jaws changed t an verbite structure (结构),making it easier t prduce such sunds.The team shwed that this change in bite was cnnected with the develpment f agriculture in the Nelithic perid.Fd became easier t chew at this pint.The jawbne didn't have t d as much wrk and s didn't grw t be s large.
Analyses f a language database als cnfirmed that there was a glbal change in the sund f wrld languages after the Nelithic age,with the use f “f” and “v” increasing remarkably during the last few thusand years.These sunds are still nt fund in the languages f many hunter-gatherer peple tday.This research verturns the ppular view that all human speech sunds were present when human beings evlved arund 300,000 years ag.“The set f speech sunds we use has nt necessarily remained stable since the appearance f human beings,but rather the huge variety f speech sunds that we find tday is the prduct f a cmplex interplay f things like bilgical change and cultural evlutin,” said Steven Mran,a member f the research team.
真题再做32.Which aspect f the human speech sund des Dami?n Blasi's research fcus n?A.Its variety.　　　　　B.Its quantity. D.Its develpment.答案 D解析 细节理解题。根据第二段的“Nw a team f researchers led by Damián Blasi at the University f Zurich,Switzerland,has fund hw and why this trend arse.”可知,Damián Blasi的研究关注的是人类语言的发展。故选D项。
33.Why was it difficult fr ancient human adults t prduce labidentals?A.They had fewer upper teeth than lwer culd nt pen and clse their lips jaws were nt cnveniently lwer frnt teeth were nt large enugh.答案 C解析 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 abut?A.Supprting evidence fr the research applicatin f the research findings.C.A further explanatin f the research methds.D.A reasnable dubt abut the research prcess.答案 A解析 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 des Steven Mran say abut the set f human speech sunds?A.It is key t effective cntributes much t cultural is a cmplex and dynamic drives the evlutin f human beings.答案 C解析 细节理解题。根据最后一段Steven Mran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。
