livingfossils.就第一项标准而言，我们可以自豪地说神农架是世界上最“完整”的自然区域之一。该地区的海拔从大约400米上升到3,000多米,被称为“华中屋脊”。海拔的巨大差异导致了迥然不同的气候环境,使得大量不同的物种得以繁衍生息。一些动植物生存了数百万年,被视为活化石。5.Forthesecondcriterion,wecanseethatShennongjiahasincrediblebiociversity.Lookatthisslide.Accordingtoofficialstatistics,over3,000plantspecieshavebeenrecordedthere.ThisrepresentsmorethantenpercentofChina'stotalfloralrichness.Shennongjiasupportsmorethan600vertebratespecies,includingtheGoldenSnub-nosedMonkeyandtheCloudedLeopard.Additionally,around4,300insectspecieshavebeenrecorded.对于第二个标准,我们可以看到神农架有着极丰富的生物多样性。请看这张幻灯片。根据官方统计，在神农架内有记录的植物物种超过3,000种，占到了中国全部开花植物的10%以上。神农架还有600多种脊椎动物,包括川金丝猴和云豹。此外,有记录的昆虫物种也达到了4,300种左右。6.ltisachallengetolookaftcrsomanyspecies.Inwinter,scientistsbraveheavysnowandfreezingtemperaturestosupplyfoodtotheGoldenSnub-nosedMonkey.Thankstotheirefforts,themonkey'spopulationhasdoubledsincethe1980s.Theirnumberreachedover1,300in2015andcontinuestogrow.照顾如此多的物种是一项挑战。冬季,科学家们不畏暴雪和严寒为川金丝猴提供食物。也正是因为他们的付出,川金丝猴的数量相比于20世纪80年代增加了一倍，到2015年达到1,300多只，而且其数量还在持续增长。7.ButthemostimpressiveaspectofShennongjiaisthelocalpeople,whotakethingsfromnaturewithoutcausingdamage.Ivisitedalocalvillagewhichisknownforits
