Unit 5 A delicate worldUnderstanding ideasMACQUARIE ISLAND：from Chaos to ConservationI am standing on Macquarie Island，in the South-west Pacific Ocean，halfway between Australia and Antarctica. Strong winds and ________(storm) seas have helped sculpt its long，thin shape. The green grass and bare rock of its landscape contrast dramatically，________(give) it a wild and natural beauty. No visitor would think it ________(surprise) that the island is a UNESCO World Heritage Site. Nor would they fail to imagine how its native inhabitants，including royal penguins，king penguins，and elephant seals，existed in perfect harmony ________ their natural habitat for thousands of years.But the island’s more recent history tells a different story. It’s a tragic story that began in 1810 when humans arrived on the island. In their ships they ________(knowing) brought rats and ________(mouse). These small animals quickly took over the island，eating the birds’ eggs and attacking baby birds. Cats were brought to the island to control the rats and mice. Unfortunately，the cats subsequently developed an appetite for the birds，too.Meanwhile，rabbits ________(introduce) to the island as a source of food for humans. Loose on the island，they did ________ rabbits do best—they multiplied rapidly and began eating the native vegetation and digging holes，________ caused soil erosion. The exploding rabbit population provided plentiful food for the cats，________(mean) that the number of cats also increased. This ________ turn led to more cats hunting the birds. The end result was that parakeets，once large in number and native to the island，died out in 1891.Even after Macquarie Island became an official nature reserve in the 1970s，the rabbits remained out of control. Experts felt ________ necessary to come up with a plan to remove all the rabbits from the island. With this goal in mind，a virus was released onto the island. But although the virus caused the rabbit population ________(decrease) from 130，000 to around 10，000，it also meant less food for the cats. The cats ________consequence turned their attention—and their stomachs—back to the native birds，killing up ________ 60，000 each year. In the 1980s，traps and dogs were used to catch the cats. The last Macquarie Island cat was caught in 2000.But as the saying goes，“While the cat’s away，the mice will play. ”With the ________(depart) of the cats from the island，the mouse and rat population started to increase. And remember those 10，000 or so rabbits? It turned ________ that they developed an immunity to the virus，and their numbers exploded once again. Then，in 2006，the rabbits’ digging caused some land to collapse，________ killed a ________(substance) number of penguins. This incident made it clear that the rat，mouse and rabbit problem needed ________(solve) once and for all.So，I am here on Macquarie Island to participate ________ the programme to tackle this very problem. The first step involved poison ________(drop) from helicopters. The next step is ________(remove) the last remaining invading species，and that’s ________ I come in—with my dogs. They have been trained to find every last one，without harming the native animals. This intervention is a long，much-delayed ending to a sad story，but we humans owe it to the island to give it a happy ending.Postscript：In 2014，Macquarie Island was declared pest-free and the island’s ecology is finally on the road to recovery.Developing ideasWHY SHENNONGJIA?Good morning，everyone. It is my great pleasure to give a lecture here ________ behalf of the Be at One with Nature Association.As we know，in 2016，Shennongjia made it onto the UNESCO World Heritage List. But there are so many important places not yet on this list. So you might ask：why Shennongjia? Is it its forests ________ stretch on and on like great green seas? Is it the legendary father of Chinese herbal medicine，Shennong，after ________ the park is named? Or is it the mysterious creature called “Yeren”（wild man）that has captured the imagination of the world?UNESCO awarded Shennongjia this status because it meets two criteria required by the list. It contains a naturally-balanced environment that allows the many and ________(variety) species to live and prosper. It is also one of the rare ________(locate) in the world where scientists can observe in real time the ecological and biological processes that occur as the plants and animals develop and evolve.For the first criterion，Shennongjia is ________(apparent) one of the most “complete” natural areas in the world. The region rises from about 400 metres to over 3，000 metres above sea level，giving it the name the “Roof of Central China”. The vast range in altitude results in a great ________(vary) in climatic conditions. This allows a wide ________(vary) of species to thrive. Some of the plants and animals have survived millions of years，and are regarded ________ living fossils.For the second criterion，we can see that Shennongjia has incredible biodiversity. Look at this slide. According to official statistics，over 3，000 plant species have been recorded there. This represents more than ten per cent of China’s total floral richness. Shennongjia supports more than 600 vertebrate species，including the Golden Snub-nosed Monkey and the Clouded Leopard. Additionally，around 4，300 insect species have been recorded.It is a challenge to look after so many species. In winter，scientists brave heavy snow and ________(freeze) temperatures to supply food ________ the Golden Snub-nosed Monkey. Thanks ________ their efforts，the monkey’s population ________(double) since the 1980s. Their number reached over 1，300 in 2015 and continues ________(grow).But the most ________(impress) aspect of Shennongjia is the local people，who take things from nature ________ causing damage. I visited a local village which is known ________ its home-made honey. ________ is special about the honey is that it is produced by the earliest species of Chinese bee. Every spring，the villagers place beehives around their houses to attract these wild bees from the forest. Althoughendangered elsewhere in China due to the invasion of foreign species，the bees of Shennongjia________(coexist) with the local people for centuries. By providing the bees with a secure home，the villagers collect their honey ________ return. This is just one of the ways in ________ people of Shennongjia live and work ________ harmony with nature.All of this explains why Shennongjia earned—and deserves—its place on the UNESCO World Heritage List，as well as highlighting how understanding，________(aware) and hard work have contributed towards protecting a unique and wonderful part of our natural world.Thank you for listening. Now，does anyone have any questions?答案：Unit 5 A delicate worldUnderstanding ideasMACQUARIE ISLAND：from Chaos to ConservationI am standing on Macquarie Island，in the South-west Pacific Ocean，halfway between Australia and Antarctica.

It is my great pleasure to give a lecture here on behalf of the Be at One with Nature Association.As we know，in 2016，Shennongjia made it onto the UNESCO World Heritage List. But there are so many important places not yet on this list. So you might ask：why Shennongjia? Is it its forests that stretch on and on like great green seas? Is it the legendary father of Chinese herbal medicine，Shennong，after whom the park is named? Or is it the mysterious creature called “Yeren”（wild man）that has captured the imagination of the world?UNESCO awarded Shennongjia this status because it meets two criteria required by the list. It contains a naturally-balanced environment that allows the many and various species to live and prosper. It is also one of the rare locations in the world where scientists can observe in real time the ecological and biological processes that occur as the plants and animals develop and evolve.For the first criterion，Shennongjia is apparently one of the most “complete” natural areas in the world. The region rises from about 400 metres to over 3，000 metres above sea level，giving it the name the “Roof of Central China”. The vast range in altitude results in a great variation in climatic conditions. This allows a wide variety of species to thrive. Some of the plants and animals have survived millions of years，and are regarded as living fossils.For the second criterion，we can see that Shennongjia has incredible biodiversity. Look at this slide. According to official statistics，over 3，000 plant species have been recorded there. This represents more than ten per cent of China’s total floral richness. Shennongjia supports more than 600 vertebrate species，including the Golden Snub-nosed Monkey and the Clouded Leopard. Additionally，around 4，300 insect species have been recorded.It is a challenge to look after so many species. In winter，scientists brave heavy snow and freezing temperatures to supply food to the Golden Snub-nosed Monkey. Thanks to their efforts，the monkey’s population has doubled since the 1980s. Their number reached over 1，300 in 2015 and continues to grow.But the most impressive aspect of Shennongjia is the local people，who take things from nature without causing damage. I visited a local village which is known for its home-made honey. What is special about the honey is that it is produced by the earliest species of Chinese bee. Every spring，the villagers place beehives around their houses to attract these wild bees from the forest. Although endangered elsewhere in China due to the invasion of foreign species，the bees of Shennongjia have coexisted with the local people for centuries. By providing the bees with a secure home，the villagers collect their honey in return. This is just one of the ways in which people ofShennongjia live and work in harmony with nature.All of this explains why Shennongjia earned—and deserves—its place on the UNESCO World Heritage List，as well as highlighting how understanding，awareness and hard work have contributed towards protecting a unique and wonderful part of our natural world.Thank you for listening. Now，does anyone have any questions?。
