According to National Geographic,emperor penguins usually raise their chicks on sea ice platforms.When these young birds are 5 months old,they lose their baby feathers and grow adult feathers,which are waterproof. Before long,the chicks have to begin their first swim in the sea to hunt by themselves.Normally,they just need to jump from the sea ice,which is less than a meter high. However,the fast-melting ice in Antarctica changes the situation.The Antarctic summer sea ice has started to decline since 2016,reported the BBC.In February 2023,the total area of sea ice reached a record low of 1.91 million square kilometers. “Penguins depend on sea ice,a stable platform for them,to bring up their young,” Peter Fretwell from UK’s national polar research institute told the BBC.If the ice platform melts or breaks apart before chicks develop their waterproof feathers,they are more likely to drown or freeze to death.For this reason,emperor penguins are now choosing to raise their babies on the ice shelf,which is firmly attached to the land.Therefore,chicks must face the challenge of jumping off a high cliff. According to Live Science,the decrease in the ice has caused thousands of emperor penguin chicks to die in West Antarctica in 2022.The continuing drop of sea ice may force more penguins to make their nests on ice shelves.“It’s heartbreaking to think that the whole species may be gone if climate change continues on the path that it’s on at the moment,” said Fretwell. 1.Which is NOT mentioned about penguin chicks in paragraph 2? A.Eating habits.　 B.Living conditions. C.Changing feathers. D.Jumping behaviour. 2.Why do emperor penguin chicks have to jump off high cliffs now? A.Their parents force them to jump. B.They want to challenge themselves. C.The ice shelves provide more food. D.The ice platforms are melting rapidly. 3.What does the underlined word “decline” probably mean in the passage? A.Appear. B.Decrease. C.Move. D.Increase. 4.What is the best title for the passage? A.A Brave Jump:The First Step to the Ocean B.Ice Shelves:The Home of Emperor Penguins C.Climate Change:A Threat to Emperor Penguins’ Survival D.Secrets of the Penguins:A Documentary about Antarctic Ⅴ.语篇填空 (2026浙江温州高一上期末) China’s long efforts to restore(修复) the population of milu deer were praised by international environmentalists as 1.　　　　　　 example for wildlife recovery.  In around 1900,milu deer were said to be 2.　　　　(official) extinct in China.However,a number of deer had been introduced to Europe.In 1985,22 milu deer 3.　　　　　　　　　(donate) to China from the UK.Since then,the number of milu deer in China has risen to 15,000.China has been able to achieve the great 4.　　　　　　(succeed) by carefully moving between zoo-based protection to wild re-establishment,5.　　　　　　 is supported by strict scientific management and habitat restoration.  China established two parks for the deer:one in Beijing as a research center,and the other in Jiangsu Province as a breeding site,similar 6.　　　　　　 the milu’s wild habitat.More than 100 breeding populations have been established in 27 provinces.7.　　　　　　(effort) to bring back wild populations have also made great progress,with six herds 8.　　　　　　(live) in different areas and numbering over 6,000.The system is the world’s largest for milu protection.  “We intend 9.　　　　　　　　　(make) milu protection a model for wildlife protection,” said Bai Jiade,director of the Beijing Milu Ecological Research Center.“In the coming years,we will further promote the reintroduction of milu into the wild 10.　　　　　 improve population management systems through modern technologies,” he added.  Ⅵ.应用文写作 (2026陕西榆林一中高一上期末) 近年来,游客投喂野生动物的事件屡屡发生,这对动物的健康造成了威胁。校英语报就此话题征文。请你以“Leave the Wild Animals Alone”为题,给校英语报写一篇短文投稿。内容包括: (1)投喂动物的危害;

To protect wildlife,we must educate tourists about the dangers of feeding animals.Parks and wildlife reserves should implement clear signage and provide information that relates to the importance of keeping a safe distance.Let’s promote responsible tourism and respect for nature. Remember,wild animals thrive best when left alone.Together,we can ensure their survival for future generations. 知识积累卡 一、1.场景;场面　2.稳定的　3.分开;散开 二、拍摄　电影 三、1.冻死　2.附着于 四、时间状语　非限制性定语　adult feathers 当这些幼鸟 5 个月大时,它们褪去幼羽,长出防水的成年羽毛。 学科网（北京）股份有限公司 $
