北师大版选修8Unit22EnvironmentalProtectionEndangeredSpecies(共15张PPT)
* Listening Strategies Listen for “topic” words, e.g. endangered, species, decrease. These words are usually stressed and the facts are often repeated, e.g. rare, few, extinct. List your main points using numbers. This makes your notes easier to read when you look at them later. Don’t try to write down everything; select important information. Use abbreviations and your own shorthand. 3. Listen to the lecture. Use the strategies to write some notes. Tapescript Today’s lecture will focus on the serious problem of endangered species. There are thousands of endangered species in the world and if the rate at which species are becoming extinct continues to rise, then millions of species will become extinct in the next decade. Most of us know about the big animals that are endangered, like tigers, but not many of us know about endangered fish or insects. There is even a type of endangered tortoise! By now, we should all be aware that the symbol for endangered species is the panda, one of the rarest animals in the world. Apart from the few found in zoos, pandas live only in the central bamboo forests of mainland China. The number of pandas has fallen because of human activity destroying much of their habitat. As pandas only eat bamboo, it is important to preserve forests for the panda’s continued existence in the wild. A survey in June 2004 showed that because of conservation efforts, the number of pandas has increased from 1000 to 1600. This is thrilling but 1600 pandas are still too few. Although 120 pandas are in special centres and 20 live in zoos around the world, we must continue our efforts to save their natural environment so they can live in the wild. Another endangered species, the Yangtze Dolphin, is China’s only fresh-water dolphin and is sometimes called “the panda of the Yangtze River” because it is so rare. Its numbers are decreasing due to pollution in the river and the fact that they are often caught by fishermen’s hooks and trapped in their nets. Hunting
