Grade Pre-2 4 B Australian Success Story In the 1900s, the population of Australia started growing quickly. Many people moved there from other countries. They started families and built new homes. Because most families did their laundry by themselves, they needed places to hang い。 wet clothes at their homes. The solution was to make a long line with rope called a clothesline in every garden on which laundry could be hung to dry. 解答欄の The first clotheslines were straight, and they could not be moved. They took up a lot of space, so people could not see the plants_and flowers that they had ることが planted. Many people felt that the clotheslines did not look good in their gardens. In addition, people had to walk_up anddown the clotheslines carrying heavy, wet clothes, which was hard work. Later, smaller deyices for hanging, clothes _were. made that people could spin around. These new types of clotheslines were more convenient and took up less space in the garden. The most popular spinning clothesline is called the Hills Hoist? It was made by a car mechanic named Lancelot_Leenard Hill in 1945. Hill's design was a big success. Every family with a small garden wanted a Hills Hoist because it was easy to use. By 1994, 5 million Hills Hoists had been sold, making it the most popular clothesline in the country. The Hills Hoist became so famous in Australia that it was printed on a postage stamp in 2009. These days, more Australian families are living in apartments that do not have gardens. As a result, fewer Hills Hoists are used in modern cities. However, for many Australians, seeing such a clothesline still brings back memories of their childhood, and many people still use one in their daily lives. 0oDrich:2020 公益財団法人日本英語検定協会 宙制を禁じます
