Human teeth are unusual compared with those of other animals. They are even in height, and the top and bottom set meet. Such regularity is surprising — it is certainly not needed for eating. It is valuable for the pronunciation of a number of sounds, such as S, F, V, SH and TH. Human lips have muscles which are considerably more developed than those in the lips of other primates. The mouth is relatively small, and can be opened and shut rapidly. This makes it simple to pronounce sounds such as P and B, which require a total stoppage of the airstream with the lips and a sudden release of pressure. The human tongue is thick, muscular and mobile, as opposed to the long, thin tongues of monkeys. The advantage of a thick tongue is that the size of the mouth cavity can be varied, allowing a range of vowels to be pronounced. [N제 p.34 64번]

① the biological importance of tongue in human metabolism

② the possibility of evolution in teeth structure for ease in digestion

③ the influence human teeth’s structure has on pronouncing sounds

④ the evolutionary history of changes in the structure of human teeth

⑤ cultural variation in the way people pronounce certain common sounds

역시 답은 스포 방지를 위해 위장용 숫자를 앞뒤에 5개씩 붙여서 달아주세요.
예를 들어 5가 답이라면 12345512345와 같이 해 주시면 됩니다.
