WHY SHENNONGJIA
Good morning, everyone.[1]It is my great pleasure to give a lecture here on behalf of① the Be at One with Nature Association.
[1]It作形式主语，动词不定式短语to give ...作真正的主语。
As we know, in 2016, Shennongjia made it② 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 [2]that stretch③ on and on like great green seas Is it the legendary④ father of Chinese herbal⑤ medicine, Shennong, [3]after whom the park is named⑥？ [4]Or is it the mysterious⑦ creature called “Yeren” (wild man) that has captured⑧ the imagination of the world
[2]that引导定语从句，修饰名词forests。
[3]after whom引导非限制性定语从句，修饰名词Shennong。
[4]本句为强调句型，强调the mysterious creature called “Yeren” (wild man)；过去分词短语called “Yeren” (wild man) 作后置定语，修饰名词creature。
UNESCO awarded Shennongjia this status⑨ [5]because it meets two criteria⑩ required by the list.It contains a naturally balanced environment [6] that allows the many and various species to live and prosper .It is also one of the rare locations in the world [7]where scientists can observe in real time the ecological and biological processes that occur as the plants and animals develop and evolve .
[5]because引导原因状语从句；过去分词短语required by the list作后置定语，修饰名词criteria。
[6]that引导定语从句，修饰名词environment。
[7]where引导定语从句，修饰名词locations；that引导定语从句，修饰名词processes；as引导时间状语从句。
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, [8]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.
[8]现在分词短语作结果状语。
①on behalf of代表
②make it (经历艰难困苦后)成功；(及时)到达(尤指来得及做某事)
③stretch v．绵延；延伸
④legendary adj.非常著名的；传奇的
⑤herbal adj.用香(药)草制成的
⑥be named after以……命名
⑦mysterious adj.神秘的
⑧capture v．引起(注意、想象、兴趣)
⑨status n．地位；身份
⑩criterion n．标准，准则
criteria (复数)
prosper v．兴旺，发达
rare adj.稀有的，罕见的
ecological adj.生态(学)的
biological adj.生物的，与生物有关的
evolve v．逐渐演变；进化
apparently adv.据说；看来，似乎
vast adj.巨大的；广大的
range n．(变动或浮动的)范围
altitude n．海拔(高度)
result in导致，引起
variation n．差异；变化
a wide variety of各种各样的，种类繁多的
thrive v．茁壮成长
be regarded as被视作；被认为
fossil n．化石
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.
[9]It is a challenge to look after so many species. In winter, scientists brave heavy snow and freezing temperatures [10]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.
[9]It作形式主语，动词不定式短语to look after so many species作真正的主语。
[10]动词不定式短语作目的状语。
But the most impressive aspect of Shennongjia is the local people, [11]who take things from nature without causing damage.I visited a local village [12]which is known for its home made honey.[13]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 [14]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 [15]in which people of Shennongjia live and work in harmony with nature.
[11]who引导非限制性定语从句，修饰the local people。
[12]which引导定语从句，修饰a local village。
[13]what引导主语从句；that引导表语从句。
[14]动词不定式短语作目的状语。
[15]in which引导定语从句，修饰名词ways。
All of this explains [16]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.
[16]why引导宾语从句。
Thank you for listening.Now, does anyone have any questions？

为什么是神农架？
大家早上好。我很开心能代表人与自然和谐相处协会在这里发表演讲。
众所周知，神农架在2016年正式入选联合国教科文组织的《世界遗产名录》。世界上重要的地方那么多，但许多都没有被列入该名单。所以你可能会问：为什么是神农架？是因为它拥有像绿色海洋般广袤的森林吗？还是因为它是以中国草药之父神农命名？抑或是叫作“野人”的神秘生物吸引了全世界的目光？
联合国教科文组织让神农架入选是因为它符合入选名录的两项标准：它拥有一个自然平衡的环境，使许多不同的物种得以生存和繁衍。它也是世界上人迹罕至之地，科学家们可以实时观察到植物和动物发展和进化过程中的生态学和生物学过程。
就第一项标准而言，我们可以自豪地说神农架是世界上最“完整”的自然区域之一。该地区的海拔从大约400米上升到3,000多米，被称为“华中屋脊”。海拔的巨大差异导致了迥然不同的气候环境，使得大量不同的物种得以繁衍生息。一些动植物生存了数百万年，被视为活化石。
对于第二个标准，我们可以看到神农架有着极丰富的生物多样性。请看这张幻灯片。根据官方统计，在神农架内有记录的植物物种超过3,000种，占到了中国全部开花植物的10%以上。神农架还有600多种脊椎动物，包括川金丝猴和云豹。此外，有记录的昆虫物种也达到了4,300种左右。
照顾如此多的物种是一项挑战。冬季，科学家们不畏暴雪和严寒为川金丝猴提供食物。也正是因为他们的付出，川金丝猴的数量相比于20世纪80年代增加了一倍，到2015年达到1,300多只，而且其数量还在持续增长。
不过神农架给人印象最深的地方还在于当地人的生活方式，他们从大自然中索取，但不会破坏生态平衡。我去了一个以自制蜂蜜而闻名的当地村庄参观。这种蜂蜜的独特之处在于它是由最古老的一种中华蜜蜂产的。每年春天，村民们就会在自家周围放置一些蜂箱，吸引森林中的野生蜜蜂。虽然在中国的其他地区，由于外来物种入侵，这种蜜蜂濒临灭绝，但是神农架的人们和这种蜜蜂已经共存了几个世纪，村民为它们提供安全住所，蜜蜂为人们提供蜂蜜。这只是神农架的村民与自然和谐相处的方式之一。
以上这些解释了为什么神农架能够并理应入选联合国教科文组织的《世界遗产名录》，同时也强调了人们的理解、认识和付出是如何促进对这一自然界独特且美好区域的保护的。

It was a village in India.The people were poor but happy.After all, their forefathers had lived in the same way for centuries.Then one day, some visitors from the city arrived.They told the villagers there were some people elsewhere who liked to eat frog's legs.However, they did not have enough frogs of their own, and so they wanted to buy frogs from other places.
This seemed like money for nothing.There were millions of frogs in the fields around, and they seemed of no use to the villagers.All they had to do was catch them.Agreement was reached.Every week a truck arrived to collect the frogs and hand over the money.For the first time, the people were able to dream of a better future.But the dream didn't last long.
The change was hardly noticed at first, but it seemed as if the crops were not doing so well.More worrying was that the children fell ill more often, and, there seemed to be more insects.
The villagers decided that they couldn't just wait to see the crops failing and the children getting weak.They would have to use the money earned to buy pesticides and medicines.Soon there was no money left.
Then the people realized what was happening.It was the frog.They had been doing an important job — eating insects.Now with so many frogs killed, the insects were increasing more rapidly.They were damaging the crops and spreading diseases.
Now, the people are still poor.But in the evenings they sit in the village square and listen to sounds of insects and frogs.These sounds of the night now have a much deeper meaning.
[理解] Read the passage and answer the following questions.1．Why did the villagers agree to catch frogs Because they wanted to get money.Besides, they didn't realise the importance of frogs.2．What can we learn from the passage The balance between man and nature is important.

MACQUARIE ISLAND：from Chaos① to Conservation②
I am standing on Macquarie Island, in the South west Pacific Ocean, halfway③ between Australia and Antarctica.Strong winds and stormy seas have helped sculpt④ its long, thin shape.The green grass and bare⑤ rock of its landscape contrast⑥ dramatically⑦， [1]giving it a wild and natural beauty.[2]No visitor would think it surprising that the island is a UNESCO World Heritage⑧ Site. [3]Nor would they fail to imagine how its native inhabitants⑨， including royal penguins⑩， king penguins, and elephant seals, existed in perfect harmony with their natural habitat for thousands of years.

But the island's more recent history tells a different story.[4]It's a tragic story that began in 1810 when humans arrived on the island. In their ships they unknowingly brought rats and mice.These small animals quickly took over the island, [5]eating the birds' eggs and attacking baby birds.Cats were brought to the island [6]to control the rats and mice.Unfortunately, the cats subsequently developed an appetite for the birds, too.

Meanwhile, rabbits were introduced to the island as a source of food for humans.Loose on the island, they did [7]what rabbits do best — they multiplied rapidly and began eating the native vegetation and digging holes, [8]which caused soil erosion.The exploding rabbit population provided plentiful food for the cats, meaning that the number of cats also increased.This in 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.[9]Experts felt it 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 to decrease from 130,000 to around 10,000, it also meant less food for the cats.The cats in consequence turned their attention — and their stomachs — back to the native birds, [10]killing up to 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.

[参考译文]
麦夸里岛：从混乱不堪到精心保护
我正站在麦夸里岛上，这里位于太平洋的西南部，澳大利亚和南极洲的中间。强风和惊涛骇浪将海岛塑成现在狭长的形状。绿草和光禿的岩石形成的景观反差巨大，使海岛呈现出一种狂野和天然的美。这座岛是联合国教科文组织确立的世界遗产，游客们都认为其名副其实。他们也不难想象出，数千年来，包括帝企鹅、王企鹅和象海豹在内的当地动物是如何与其自然栖息地完美地和谐共存的。
但是，这座岛近些年的遭遇则是截然不同的故事。悲剧从人类1810年来到这座岛屿开始。他们不经意间随船带来了大鼠和小鼠。这些小动物很快就占领了岛屿，它们吃鸟蛋并攻击幼鸟。为控制鼠患，人们带来了猫，但不幸的是，猫随后也开始以鸟为食。
与此同时，人们把兔子引进岛上作为食物。由于在岛上放任其生存，兔子做了自己最擅长的事——飞快地繁殖，它们开始吃当地植被并挖洞，造成了土壤侵蚀。爆炸式增长的兔子数量给猫提供了充足的食物，这意味着猫的数量也增加了，相应地就有更多猫捕食鸟类。最终结果是，曾经数量众多的当地物种长尾小鹦鹉在1891年灭绝。
即使在20世纪70年代麦夸里岛成为官方自然保护区后，兔子仍然不受控制。专家认为，必须想办法清除岛上所有的兔子。怀着这个目标，人们投放了一种病毒到岛上。然而，虽然病毒使得兔子的数量从130,000降到约10,000只，但这也意味着猫的食物变少了。因此，猫把注意力和胃口重新转向了当地鸟类，每年捕食多达60,000只。20世纪80年代，人们利用捕猎夹和狗来抓猫。2000年，麦夸里岛上的最后一只猫被抓。
但正如俗语所说，“山中无老虎，猴子称大王”。猫从岛上消失了，小鼠和大鼠的数量便开始增加。还记得那10,000只左右的兔子吗？它们最终对病毒产生了免疫，数量又一次激增。随后，在2006年，兔子挖的洞造成一些土地坍塌，导致大量企鹅死亡。这一事件清楚地表明，大鼠、小鼠和兔子泛滥的问题需要一次彻底地解决。
所以，正是为了解决这个问题，我来到麦夸里岛上参与一项行动。行动的第一步利用了直升机向岛上投放毒药。下一步是清除最后残存的入侵物种，这就是我的工作了——和我的狗一起。这些狗受训去寻找剩下的每一只老鼠和兔子，同时又不伤害当地动物。这次干预行动是这场悲剧漫长而屡被贻误的大结局，但这是我们人类应该做的，我们亏欠这座岛屿一个美好的结局。
附言：2014年，麦夸里岛正式宣布已无有害生物，岛上的生态环境终于走上了恢复之路。
