What roles do the questions in Paragraph 2 play
Para. 1: Good morning, everyone. It is my great pleasure to give a lecture here on behalf of the Be at One with Nature Association.
Para. 2: 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
They serve to introduce the topic and attract the audience.

Para. 3 Criteria for selection
What are the criteria required by the UNESCO World Heritage List
Para. 3: 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.
Containing a naturally-balanced environment and being one of the rare locations in the world where scientists can observe in real time the ecological and biological processes.
Para. 4 Criteria for selection
What makes Shennongjia the most “complete” natural areas in the world
Para. 4: 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.

What roles do the questions in Paragraph 2 play
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 harmony with the nature. They take things from nature without damaging it.
Which part of Shennongjia interests you most Why
I admire the local people who live in harmony with nature and I like their way of life.
Work in groups. Give a talk comparing Macquarie Island and Shennongjia.
Think about the similarities and differences between Macquarie Island and Shennongjia and make notes.
Similarities: Differences:
Both have unique animals. Macquarie is an island, while Shennongjia is a mountainous area.
Post-reading
Similarities: Differences:
Both have wild and natural beauty.
Both are UNESCO World Heritage Sites.
Macquarie Island was once in chaos due to the introduction of non-native species, while Shennongjia has always been in natural harmony.
The native species of Macquarie Island existed for thousands of years, while some of the plants and animals in Shennongjia have survived over millions of years.
Shennongjia has more varied species of plants and animals than Macquarie island.
Decide what conclusions you can draw from comparing the two places and what you would like to include in your talk.
Give your talk to the class.
Humans are only part of naturally-balanced nature as the animals. We should live without disturbing the normal ecosystem or we'll be punished by nature.

The Wonders of Fanjing Mountain
Good afternoon, everyone! I'm very happy to be here to give a short lecture.
Have you ever heard of Fanjing Mountain Or have you ever visited it If you haven't, you soon will! Fanjing Mountain lies in Tongren, Guizhou Province with an elevation of about 2,570 metres. It is the highest peak of the Wuling Mountain range in south-west China. Fanjing Mountain was added to the UNESCO World Heritage List in 2018.
The Fanjingshan Nature Reserve was established in 1978 and represents one of the country's greatest achievements in environmental protection. The rich biodiversity of the Wuling Mountain range is the principal reason for Fanjing Mountain's inclusion in the UNESCO World Heritage prising the largest subtropical primeval beech forest, the region is home to 2,000 species of plants, such as the endangered Chinese dove tree. Endangered animal species that can be found on Fanjing Mountain and its surrounding mountain range include the Chinese giant salamander, forest musk deer and grey snub-nosed monkey.
Fanjing mountain is of course also renowned for the breathtaking views from its summit—or, more accurately “summits”, as there are three of these! And when night falls leaving this magnificent scenery in darkness, the Mushroom Stone, one of the many strange rock formations, is illuminated so that visitors can still marvel at the wonders of Fanjing Mountain.
All explains why Fanjing Mountain earned its place on the UNESCO World Heritage List.
