2、disappeared leaving only us humans behind, the human race would not be able to survive. The rapid urbanization of cities in modern times poses a great threat to the existence of some animals. Along with the loss of the natural habitats, man-made activities add fuel to the flames, accelerating the ra

Students will get to know the current situation of some animal species through reading, listening and viewing. Various activities will inspire students to talk about humans impact on na

Finally, they will conduct a poll on “college students awareness of endangered species in China” with their peers.,Unit Overview,Background Information,Industrialization, economic development and population pressure have in the past two centuries

5、 combined to result in a rapid loss of biological diversity and an acceleration in the number of species disappearing from the face of the earth. According to the IUCN (World Conservation Union), in the last 500 years human activity has forced 816 species to extinction. As biological diversity is lo

6、st, we also lose the possibility of tapping as yet unknown resources for agriculture, industry, and health care. Chinas biological resources are among th e worlds richest. This is not only due t o its size, but also due to the tremendous diversity of habitats it provides for wild plants and animals.

7、 The worlds highest and lowest points are in Chinese territory, and it has a variety of ecosystems that is unequalled else where, from glaciers t o coral reefs, from deserts to tropical rainforests. As a result, China s diversity of wild plants and animals is greater than all of North America or Eur

8、ope, and equal to one eighth of all species on Earth.,Basic facts There are over 385 threatened species in China (according to the IUCN Red List) Giant pandas have lost half their habitat between 1974 and 1989 In the past century, the world lost over 90% of its tiger population; in China, there are

9、only about 90 tigers left in the wild Endangered species in China include the giant panda, golden monkey, South China tiger, Siberian tiger, Asian elephant, black-necked crane, crested ibis, saunders gull, dugong, Yangtze river dolphin, plus many lesser-known species. Key threats Habitat loss, fragm

10、entation, and degradation because of human activities such as logging or mineral exploitation Wildlife trade and the illegal hunting of species such as musk deer and bears, whose body parts are used in traditional Chinese medicines Pollution and climate change,Solutions The best way to preserve biol

11、ogical diversity is to maintain flora and fauna in their natural ecosystems. This can be achieved by controlling unsustainable actions such as poaching, as well as by setting up protected areas, and encouraging sustainable use of natural resources. Because the existence of flora and fauna are also t

12、hreatened by pollution and climate change, sustainable development and the decrease of wasteful consumption in affluent areas are ultimately the key.,Lesson One,Lead-in,Audio studio,Video studio,Speaking workshop,Project bulletin,Lead-in,Task 1,Task 2,Task 3,Task 1 Describing the Picture,Describe th

Why did Smits fail to make a big difference to slo

24、xpect a high-tech city, there are also some parts of the island that still reflect how it used to look before urban development took over. In one of the main Central Nature Reserves, monkeys still roam freely, living side by side with humans. The macaques have grown accustomed to being fed, so they

25、look to humans as a source of food. But this in itself is problematic. As the monkeys depend more on humans for food, they venture further from their natural habitat, a phenomenon that has worried experts. There is just not enough space. Essentially, in much of Southeast Asia weve seen a lot of habi

26、tat loss where rainforest has been destroyed and converted into human settlement. Singapore is a very urbanized city, and its taken a lot of space, so there is not much space left for long-tailed macaques. We really need to stop encroaching into nature reserves. We need to stop building the houses s

27、o nearby the reserves, which then causes the problem of the macaques coming into peoples houses and raiding them. These macaques are French species so they live on the edges of the rainforests. If humans keep building the houses so near the reserves, there will definitely be a constant human-macaque

28、 conflict issue. After all, the macaques are essential to maintaining the rainforests ecosystem. More should be done to protect them.,Script,Video Studio,Word Bank, statistics 統(tǒng)計(jì)資料 capture 捕捉 1. odyssey 長途的冒險(xiǎn)行程 2. expanse 廣闊的區(qū)域 hostile 敵意的 3. bison 北美野牛 4. grizzly 灰熊 (產(chǎn)于北美) 5. extinct (尤指某種動(dòng)物等) 滅絕的
