It is produced by the earliest species of Chinese bee．　 7．What roles do the questions play in paragraph 2? To interest the audience and introduce the topic of the lecture. 8．How do the scientists protect the species? They brave heavy snow and freezing temperatures to look after the species. As we know, in 2016, Shennongjia made it onto the UNESCO World Heritage List. UNESCO awarded Shennongjia this status because it meets two criteria 1.required(require)by the list. For the first criterion, Shennongjia is 2.apparently(apparent)one of the most “complete” natural areas in the world. The vast range in altitude results in a great 3.variation(vary)in climatic conditions, which allows a wide variety of species 4.to thrive(thrive). For the second criterion, Shennongjia has over 3，000 plant species, 5.representing(represent) more than ten per cent of China's total floral richness. It is a challenge to look 6.after so many species. Thanks to the scientists' efforts, the monkey's population 7.has doubled(double) since the 1980s. But 8.the most impressive aspect of Shennongjia is the local people, who take things from nature without causing damage. By 9.providing(provide) the bees with a secure home, the villagers collect their honey in return. All of this explains 10.why Shennongjia earned—and deserves—its place on the UNESCO World Heritage List. Ⅰ.阅读词汇·识记 选出与单词对应的汉语释义 1．dissolve v.　　　　　　 A．茁壮成长 2．herbal adj. B．花的 3．status n.
