《Wildlife Protection》Section A PPT 第一部分内容：晨读晚诵 动物是人类亲密的朋友,人类是动物信赖的伙伴。人类的生存不能没有动物,而动物完全可以不需要人类!保护野生动物,就是关爱人类自己。 Many animal and plant species have become extinct and many more are in critical danger. Dodo The dodo is a classic example of how humans caused damage to the earth’s biology.The flightless dodo was native to the Island of Mauritius in the Indian Ocean.The easily controlled bird became a source of food for sailors and was attacked by animals introduced to the island by humans such as pigs,monkeys and rats.The population of dodos rapidly decreased and the last one was killed in 1681.  Rhinos The rhino horn is a highly prized item for Asian medicine.This has led to the animal being hunted in its natural habitat.Once widespread in Africa and Eurasia,most rhinos now live in protected natural parks and reserves.Their numbers have rapidly decreased① in the last 50 years,and the animals remain under constant threat from poachers(偷猎者). Whales The International Whaling Commission is fighting to ensure② the survival of the whale species.Despite the fact that one-third of the world’s oceans have been declared whale sanctuaries (保护区),7 out of 13 whale species remain endangered.Collisions (碰撞) with ships,poisonous pollution③ and being caught in fishing nets are some major causes of whale deaths. Tigers The last 100 years has seen a 95% reduction in the numbers of remaining tigers to between 5,000 and 7,000 and the Bali,Javan,and Caspian tigers are already extinct.The South China tiger is precariously(危险地) close to disappearing④,with only 20 to 30 still alive.Like the rhino horn,tigers’ bones and organs are sought after for medicines.These items are traded illegally along with tiger skins. 词海拾贝 ①decrease v.减少 ②ensure vt.保证 ③pollution n.污染 ④disappear vi.消失 典句欣赏 The easily controlled bird became a source of food for sailors and was attacked by animals introduced to the island by humans such as pigs,monkeys and rats. 翻译:这种容易被控制的鸟成了水手的食物来源,同时受到人们带来的动物,诸如猪、猴子和老鼠的攻击。 分析:本句是一个简单句。句子的主语是The easily controlled bird,became和was attacked是并列谓语,introduced to the island...是动词-ed形式构成的短语作定语。 理解诱思 1.What does the passage mainly tell us? 答案:Some extinct and endangered animals. 2.What should we do to prevent these animals from extinction? 答案:Open. ... ... ...
