UNIT 2　WILDLIFE PROTECTION Ⅰ.阅读理解 A (2023·广东高三月考)Every summer，the Serengeti plains of Africa are worth visiting.Millions of wild animals begin their 1,800­mile journey northwards on their annual migratory (迁移的) route. 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 bear's 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 Nation's 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 animal's 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.
