《Wildlife Protection》Section A PPT
第一部分內(nèi)容：晨讀晚誦
動物是人類親密的朋友,人類是動物信賴的伙伴。人類的生存不能沒有動物,而動物完全可以不需要人類!保護野生動物,就是關(guān)愛人類自己。
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(偷獵者).
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 (保護區(qū)),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(危險地) 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.
詞海拾貝
①decrease v.減少
②ensure vt.保證
③pollution n.污染
④disappear vi.消失
典句欣賞
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.
翻譯:這種容易被控制的鳥成了水手的食物來源,同時受到人們帶來的動物,諸如豬、猴子和老鼠的攻擊。
分析:本句是一個簡單句。句子的主語是The easily controlled bird,became和was attacked是并列謂語,introduced to the island...是動詞-ed形式構(gòu)成的短語作定語。
