по тексту
The Harper family live in a large , comfortable home . Like many other houses , it has all modern conveniences .Unlike many other houses , it has no windows . The Harpers live in Coober Pedy , Australia , where two thirds of the population live underground . Coober Pedy is an opal-mining town in the Australian desert . Above ground , the town does not look very welcoming .The earth is red and dry under the scorchong sun . There is a small number of shops and offices . Underground , however , it's a very different story . There are shops , hotels , restaurants and churches , all built underground to escape from the extreme temperatures and violent dust storns of the desert . The underground dwellings range from dugouts to luxurious caverns with beautifil furniture . The Harper family home has 3 spacious bedrooms and a large living room . The Harper children , Tom and Wendy , spend most of their time in the games room or swimming pool ! The house is clear and comfortable and the Harpers enjoy entertaining guests there . The Harper's beautiful home is a result of their own hard work , as it was once just a small , two-room cave home . "The advantage of living underground is that , if you need another room , you just dig it !" says Mr. Harper . "And the advantage of living in an opal-mining town is that you often find opals while you are extending your house !" Besides , children can make as much noise as they want ,because the walls are soundproof . The underground homes at Coober Pedy offer an interesting way of life , as well as peace and quiet and relief from the deaert sun . The Harper family are certainly content . "Life is so much simpler underground , "says Wendy . "I can't imagine living anywhere else ."
