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 naturallybalanced 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。
