Ⅰ.原文释译
WHY SHENNONGJIA
Good morning，everyone. It is my great pleasure to give a lecture here on behalf of ① 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 stretch② on and on like great green seas？Is it the legendary③ father of Chinese herbal④ medicine，Shennong， after whom the park is named⑤？Or is it the mysterious⑥ creature called “Yeren” (wild man) that has captured the imagination of ⑦ the world
UNESCO awarded Shennongjia this status⑧ because it meets two criteria⑨ required by the list.It contains a naturally-balanced environment that allows the many and various species to live and prosper⑩. 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.
