Think&Share:
2. According to the passage, what has been done to protect the ecology of Shennongjia
The questions in Paragraph 2 serve to introduce the topic and attract the audience.
To protect the ecology of Shennongjia, scientists make every effort to look after the species. In winter, scientists brave heavy snow and freezing temperatures to supply food to the Golden Snub-nosed Monkey. More importantly, the local people live in harmoy with nature. They take things from nature without damaging it.
Why Shennongjia
Good morning, everyone. It is my great pleasure to give a lecture here on behalf of the Be at One with Nature Association.

Why Shennongjia
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
succeed
Why Shennongjia
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.
句意：联合国教科文组织令神农架入选是因为它符合入选名录的两项标准。

UNESCO awarded Shennongjia this status because it meets two criteria required by the list.
criterion n. （批评判断的）标准；准则；规范；准据
pl. criteria
1. Practice is the sole _______ for testing truth.
2. It is hard to make out what
______ are used.
3. Each of us will have our own
_______ for success.
criteria
criterion
criteria
Why Shennongjia
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.
句意：作为第一个标准，神农架显然是世界上最“完整”的自然区域之一。

For the first criterion, Shennongjia is apparently one of the most “complete” natural areas in the world.
apparently adv.据说；看来，似乎；显然地
apparent adj.显而易见的；显然的；表面上的
It is apparent that... ……是很显然的
例：
1. _________ the girls are not at all amused by the

The region rises from about 400 metres to over 3,000 metres above sea level, giving it the name the “Roof of Central China”．
句意：这一地区从海拔400米左右上升到3000米以上，因此得名“华中屋脊”。

现在分词短语作结果状语
1. Up to 50% of the area's population died from
this epidemic, making it one of the main causes
of the fall of the Roman Empire.
2. The child slipped and fell, hitting his head against
the door.
作为结果状语的现在分词短语所表示的通常都是意料中的结果。不定式作结果状语通常表示的是未曾料到的不愉快的结果。
Why Shennongjia
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.
Why Shennongjia
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.
句意：冬季，科学家们不畏暴雪和严寒为川金丝猴提供食物。
brave v. 勇敢面对，冒（风险）；展示勇敢
1. Thousands have braved icy rain to demonstrate
their support.
2. Hundreds of fans braved rush-hour traffic to see
the concert.

形容词作动词
【拓展】常见的形容词作动词的还有empty，意为“倒空”。
He empties all the things in the bag onto the floor.
Why Shennongjia
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 of Shennongjia live and work in harmony with nature.
Why Shennongjia
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
句意：然后，使用数据、示例和比较来支持主要观点。
comparison n．比较；对比
by comparison 比较起来；相比之下
