In the month of November,polar bears in their thousands cross the Canadian Arctic,as they head towards the ice sheets of Hudson Bay.The sea ice that forms every winter is the key to the bears managing to exist,for here they hunt for seals (海豹). The Great Bustard,one of the heaviest flying birds,migrates each year across Europe and Asia to its wintering grounds.Unluckily,these and other migratory animals are in danger from human activity. We have written several articles on climate change and the effect of rising ocean temperatures.Since 1979,ice sheets in the Arctic have gone down by 30 percent.What does this mean for polar bears?They are forced to stay on land for longer periods of time,which delays their search for food.As a result,bears today are 60 pounds lighter than what they were.Besides,smaller bears also produce weaker babies,and their chances of survival are at risk.In the plains of Africa,migratory animals like gazelles are traveling long distances for food,just to avoid falling prey (牺牲品) to humans who hunt them. In an unusual step,experts from 120 countries have agreed to protect 31 migratory mammals,fish and birds.The United Nations 11th annual Conservation of Migratory Species of Wild Animals (CMS) was held in Quito,Ecuador.For the first time,900 experts attended the conference,and the enthusiastic support shows the world is united in conservation (保护) efforts. What does getting on a protected list mean?Countries that have signed the agreement will be required to pass laws locally and work with other countries that fall within the animals migratory path.Only one animal did not make the list.The African lion was rejected (拒绝) for lack of information of the countries where it lives. 【语篇解读】本文是一篇生态环保类说明文,介绍了很多野生动物在迁徙途中遭受人类的捕杀 或受到人类活动的影响导致数量急剧下降,因此专家们呼吁世界各国联合起来保护迁徙物种。 4.What can we learn from the passage?

A.let us know about the animals B.prevent the rare animals from dying out C.inform us of the effects of climate change D.draw our attention to helping the migratory animals 答案 D 解析推理判断题。通读文章可知,很多野生动物在迁徙途中遭受人类的捕杀或受到人类活动的影响 导致数量急剧下降,在联合国第 11 届野生动物迁徙物种年度保护大会上,专家们呼吁世界各国联合 起来保护迁徙物种。由此可知,本文的目的是引起人们的注意来帮助保护迁徙动物,故 D 项正确。 -1- UNIT 2 WILDLIFE PROTECTION 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 earths 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. 晨读晚诵 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 decreased in the last 50 years,and the animals remain under constant threat from poachers(偷 猎者). 晨读晚诵 Whales The International Whaling Commission is fighting to ensure the survival of the whale species.Despite the fact that one-third of the worlds oceans have been declared whale sanctuaries (保护区),7 out of 13 whale species remain endangered.Collisions (碰撞) with ships,poisonous pollution and being caught in fishing nets are some major causes of whale deaths. 晨读晚诵 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 disappearing,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. 晨读晚诵 词海拾贝 decrease v.减少 ensure vt.保证 pollution n.污染 disappear 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。 晨读晚诵 理解诱思 1.What does the passage mainly tell us?
