*** 5 Section 2 Dances Around the World Why did people create Irish dance? The next example is Irish dance. It is famous for the dancers' quick steps. This dance dates back to the 16th century. In those days, Ireland was a colony of England. People there were not allowed to perform their traditional music or dance. As a result, Irish people quietly sang their songs indoors and created a new way of dancing. In the dance, they did not move their upper bodies. They only moved their legs. Thus, when someone outside looked through 10 the window, the person could not tell if they were dancing. G Irish people tried to protect their tradition by stamping their feet to their own music. The dance shows Irish people's quiet but strong resistance against 15 England at the time. ♦Ireland [áiǝrlənd] colony [kálǝni] allow(ed) [ǝláu(d)])) perform [pǝrf5:rm] quietly [kwáiǝtli] indoors [indó:rz] upper [Ápǝr] resistance [rizistǝns] アイリッシュダンスを踊る人々 (1950年代) Q & 1.
