7、 of the world?众所周知，神农架在2016年正式入选联合国教科文组织的世界遗产名录。世界上重要的地方那么多，但许多都没有被列入该名单。所以你可能会问：为什么是神农架？是因为它拥有像绿色海洋般广袤的森林吗？还是因为它是以中国草药之父神农命名？抑或是因为神秘的“野人”吸引了全世界的目光？Developing ideas While reading Is it the legendary father of Chinese herbal medicine,Shennong,after whom the park is named?本句为强调句式“It is.who.”，由于name af

8、ter中的after提前，who改为whom。原强调句应为：Is it the legendary father of Chinese herbal medicine,Shennong,who the park is named after?【句子分析】Or is it the mysterious creature called“Yeren”(wild man)that has captured the imagination of the world?本句也为强调句式“It is.that.”，其中“called“Yeren”(wild man)”作后置定语修饰creature。Devel

10、 in real time the ecological and biological processes that occur as the plants and animals develop and evolve.联合国教科文组织令神农架入选是因为它符合入选名录的两项标准：它拥有一个自然平衡的环境，使许多不同的物种得以生存和繁衍。它也是世界上人迹罕至之地，科学家们可以实时观察到植物和动物发展和进化过程中的生态学和生物学过程。Developing ideas While reading UNESCO awarded Shennongjia this status because it me

13、s 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

14、 are regarded as living fossils.就第一项标准而言，神农架显然是世界上最“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。现在分词短语作状语，对前面内容进行补现在分词短语作状语，对前面内容进行补充说明。充说明。Developing ideas While reading For the second criterion,we can see that Shennongjia has incredible biod

19、s home-made honey.What is special about the honey is that it is produced by the earliest species of Chinese bee.Every spring,the villagers place beehives around their houses to attract these wild bees from the forest.不过神农架给人印象最深的还在于当地人的生活方式，他们从大自然中索取，但不会破坏生态平衡。我去了一个以自制蜂蜜而闻名的当地村庄参观。这种蜂蜜的独特之处在于它是由最古老的

22、个世纪，村民为它们提供安全住所，蜜蜂为人们提供蜂蜜。这只是神农架的村民与自然和谐相处的方式之一。“连 词 A l t h o u g h +endangered elsewhere in China”结构作让步状语；due to the invasion of foreign species介词短语作原因状语；in which引导的定语从句，修饰先行词ways。Developing ideas While reading All of this explains why Shennongjia earnedand deservesits place on the UNESCO World He

24、大家的聆听。现在大家有什么问题吗？why引导宾语从句；how引导宾语从句；as well as highlighting是介词短语，highlighting在意思上与explains并列，但在语法逻辑上，此处是介词短语作状语，起补充说明作用。Developing ideas After reading Activity 3.Read the sentences from the passage and decide if they serve to give data(D),examples(E)or make comparisons(C).1.The region rises from ab
