1 Where is Shennngjia and what is it famus fr?
2 What else d yu knw abut Shennngjia?
Shennngjia lies in the nrth-west f Hubei Prvince and is famus fr its beautyand diversity.
Lk at the title f the passage and think abut what it means.
Nw read the passage and check yur answer.
The title raises a questin: why did Shennngjia make it nt the UNESCO Wrld Heritage List?
Gd mrning, everyne. It is my great pleasure t give a lecture here n behalf f the Be at One with Nature Assciatin. As we knw, in 2016, Shennngjia made it nt the UNESCO Wrld Heritage List. But there are s many imprtant places nt yet n this list. S yu might ask: why Shennngjia? Is it its frests that stretch n and n like great green seas? Is it the legendary father f Chinese herbal medicine, Shennng, after whm the park is named? Or is it the mysterius creature called “Yeren” (wild man) that has captured the imaginatin f the wrld?
UNESCO awarded Shennngjia this status because it meets tw criteria required by the list. It cntains a naturally-balanced envirnment that allws the many and varius species t live and prsper. It is als ne f the rare lcatins in the wrld where scientists can bserve in real time the eclgical and bilgical prcesses that ccur as the plants and animals develp and evlve.
Fr the first criterin, Shennngjia is apparently ne f the mst “cmplete” natural areas in the wrld. The regin rises frm abut 400 metres t ver 3,000 metres abve sea level, giving it the name the “Rf f Central China”. The vast range in altitude results in a great variatin in climatic cnditins. This allws a wide variety f species t thrive. Sme f the plants and animals have survived millins f years, and are regarded as living fssils.
Fr the secnd criterin, we can see that Shennngjia has incredible bidiversity. Lk at this slide. Accrding t fficial statistics, ver 3,000 plant species have been recrded there. This represents mre than ten per cent f China’s ttal flral richness. Shennngjia supprts mre than 600 vertebrate species, including the Glden Snub-nsed Mnkey and the Cluded Lepard. Additinally, arund 4,300 insect species have been recrded.
It is a challenge t lk after s many species. In winter, scientists brave heavy snw and freezing temperatures t supply fd t the Glden Snub-nsed Mnkey. Thanks t their effrts, the mnkey’s ppulatin has dubled since the 1980s. Their number reached ver 1,300 in 2015 and cntinues t grw.
But the mst impressive aspect f Shennngjia is the lcal peple, wh take things frm nature withut causing damage. I visited a lcal village which is knwn fr its hme-made hney. What is special abut the hney is that it is prduced by the earliest species f Chinese bee. Every spring, the villagers place beehives arund their huses t attract these wild bees frm the frest. Althugh endangered elsewhere in China due t the invasin f freign species, the bees f Shennngjia have cexisted with the lcal peple fr centuries. By prviding the bees with a secure hme, the villagers cllect their hney in return. This is just ne f the ways in which peple f Shennngjia live and wrk in harmny with nature.
All f this explains why Shennngjia earned – and deserves – its place n the UNESCO Wrld Heritage List, as well as highlighting hw understanding, awareness and hard wrk have cntributed twards prtecting a unique and wnderful part f ur natural wrld. Thank yu fr listening. Nw, des anyne have any questins?
Read the sentences frm the passage and decide if they serve t give data (D), examples (E) r make cmparisns (C).
1 What rles d the questins in Paragraph 2 play?
The questins in Paragraph 2 serve t intrduce the tpic and attract the audience.
2 Accrding t the passage, what has been dne t prtect the eclgy f Shennngjia?3 Which part f Shennngjia interests yu mst? Why?
T prtect the eclgy f Shennngjia, scientists make every effrt t lk after the species. In winter, scientists brave heavy snw and freezing temperatures t supply fd t the Glden Snub-nsed Mnkey. Mre imprtantly, the lcal peple live in harmny with nature. They take things frm nature withut damaging it.
