15 The secret of how to make a perfect cup of tea has finally been discovered by put the milk in first. The finding that a cup of tea tastes better English scientists if the tea is poured into the milk appeared to have settled an argument that has been of major concern to this nation of tea drinkers. 52 It all began after Dr. *Andrew Stapley, a chemical engineer at *Loughborough University, revealed 3) the recipe for a perfect cup of tea. He said the keys to producing the perfect cup were using *soft water, warming the pot and allowing the tea to stand for three minutes. As to the difficult issue of whether the milk or tea should be poured in first, Dr. Stapley said science proved it must be the former. The reason is that 10 when milk is exposed to high temperatures, such as being poured into a cup of very hot tea, it loses its fresh taste. 3 However, only a few hours after Dr. Stapley announced his findings to the world, a noisy debate started within the scientific community. Dr. Julia King, head of the *Institute of Physics, said the secret was to keep the water temperature at 98°C. Putting the milk in first was only a social custom that "has nothing to do with taste," she said. "In the past, only the rich could afford high quality *china cups which could withstand the hot tea being poured in directly. In contrast, those of us with cheap china had to put the milk in first to prevent our cups from cracking." ウ 262 words)

*** 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.
