Unit 6 Nurturing nature It is November,springtime in the Australian desert,and I am standing at the base of the massive rust-coloured monolith ① known as Uluru,or Ayers Rock,along with a group of travelers whom I am guiding on a two-week tour of Australia and New Zealand.Above us a path snakes up the smooth face of the sandstone rock. Since the 1930s,when this formation started to become known to outsiders—and then became one of Australia ’ s top tourist attractions—hundreds of thousands of visitors have climbed this track to the top of the rock. But not today.A sign at the start of the track says the climb is closed due to extreme heat and a risk of high winds. And a short time from now,not ever.Two days before our arrival,the Uluru-Kata Tjuta National Park board announced that from October 26,2019,Uluru will be permanently ② closed to climbing. For the rock ’ s Aboriginal owners,whose tenure here goes back tens of thousands of years,this is a momentous ③ decision,one they have dreamed of and worked toward for decades.To them,Uluru is an intensely sacred site and a potent link to spirit ancestors who shaped the land.For the best part of a century,they have felt sickened as people defecated on,stripped naked on,and drove golf balls off this spot where Aboriginals believe that the spirits of ancestral ④ beings continue to live. In Aboriginal life,sacred stories are not just narrative accounts of something that happened once.They can be powerful charms to ancestral presences that remain active in “country”—the English word used to express the deep Aboriginal relationship to land.Country is like a family member.If the story is wrong,country suffers.When country suffers,people suffer .   There is a moment just before the sun sets when the west-facing flanks ⑤ of Uluru blaze orange as if the rock has caught fire. The glow is fierce,intense,alive.A quarter of a million people come each year to watch this symphony of light and,increasingly,to learn something of the oldest living civilization on Earth.   By not climbing,they honour Aboriginal Tjukurpa.By honouring Tjukurpa,they honour the land. 词海拾贝 ① monolith n. 巨型独石 ; 庞然大物 ② permanently adv. 永存地 ; 不变地 ③ momentous adj. 重大的 ; 重要的 ④ ancestral adj. 祖先的 ; 祖传的 ⑤ flank n. 侧面 , 侧腹 典句欣赏 There is a moment just before the sun sets when the west-facing flanks of Uluru blaze orange as if the rock has caught fire. 译文 : 就在太阳下山前一刻 , 乌鲁鲁的西侧被夕阳映成橙色 , 仿佛着火了一样。 分析 : 这是一个复合句。 before 引导时间状语从句 ,when 引导时间状语从句。 as if 引导方式状语从句。 理解诱思 1 .Why did Australian government close the climbing of Uluru? 答案 : To protect Uluru and worship the Aboriginal culture. 2 .What does Uluru stand for in the eyes of Aboriginals? 答案 : Uluru is a great sacred place which is related to their ancestors who lived on the land.
