Then you state your status and give a speech on behalf of your school. The topic of the speech is related to biological variation, as well as the protection of endangered plants and animals. You can take Shennongjia as an example. Its mysterious not only because its named after Shennong, the father of Chinese herbal medicine, but because it is on the UNESCO World Heritage List. One criterion is apparently its location and altitude. The vast range in altitude results in a great variation in climatic conditions. This allows a variety of rare species to prosper and thrive. Even some species are regarded as living fossils. Its worth mentioning that though endangered elsewhere in China due to the invasion of foreign species, the bees of Shennongjia have coexisted with the local people for centuries, who provide the bees with a secure home.活动的一个环节是观看视频，获取视觉信息，给出你的示例和比较。然后说明你的身份，并代表你的学校发表演讲。演讲的主题涉及生物 变异，以及濒危动植物的保护。你可以以神农架为例。它之所以神秘，不仅因为它是以中草药之父神农命名的，还因为它被列人了联合国教科文组织的世界遗产名录。其中一个标准 据说是它的位置和海拔高度。在高度上的广阔幅度导致了气候条件的巨大变化。这使得各种各样的稀有物种得以繁行生息和茁壮成长。甚至有些物种被认为是活化石。值得一提的是，尽管由于外来物种的人侵，中华蜜蜂已经在中国其他地方濒临灭绝，但神农架的蜜蜂已经与当地人共存了几个世纪，他们为蜜蜂提供了一个安全的家园。Step 3 Words transformation1._ v.兴旺；发达_ n.兴旺；繁荣2._ adj. 稀有的；罕见的_ adv.稀有；很少3._adv.据说；看来；似乎_ adj. 显而易见的4._ adj.濒临灭绝的_ v.灭绝5._ n.涌入；侵略_ v. 涌入；侵略6. _ n.差异；变化_ v.变化_ adj.各种各样的_ n. 多样化_ (词组各种各样的)7. _ adj. 稳固的；安全的_ adv._ n.安全Step 4 Key words1. comparison n. 比较 compare v.对比 1) in/by comparison with 与.对比2) make a comparison 作比较In comparison with the previous study, the new study expanded research subjects.与之前的研究相比，新研究拓宽了研究主题。It is hard to make a comparison with her previous book- they are completely different.很难与她以前的书对比 两者截然不同。3) compare A with B 把 A 和 B 进行比较4) compared with/to 与.相比(在句中作状语)Compared with our small flat, Bills house seemed like a palace.与我们的小公寓相比，别人的房子就像是宫殿。2. on behalf of/ on ones behalf 代表；为了某人On behalf of my whole family, Id like to extend my sincere gratitude for your help. 我谨代表我全家对你们的帮助表示真诚的感谢。Please dont leave on my behalf. 请不要因为我离开。Exercises:1.
