All of this even before the
marvelous discovery that when humans were able to produce words and string
them together in sentences,not all sounds sounded alike.这句话怎么翻译啊,
(At the birth of arts such as music,dance,and painting,people probably intended to communicate to others information about threats and opportunities,about
their own sadness or joy,and about shaping social behavior.But in parallel to
communication,the arts would also have produced a homeostatic compensation.
If they had not,would they have prevailed?All of this even before the
marvelous discovery that when humans were able to produce words and string
them together in sentences,not all sounds sounded alike.The sounds had natural
accents,and the accents could have relationships in time.Accents could create
rhythms,and certain rhythms would create pleasure.Poetry could begin,and the
technique could eventually feed back into the practice of music and dance.)这是前后文
