As global temperatures continue to rise, these ecosystems are experiencing significant changes. One of the most visible effects is the melting of glaciers. In the Alps, for example, glaciers have lost about half of their volume since 1900. This has serious consequences. Rivers that depend on glacial meltwater are becoming drier in summer, affecting agriculture and drinking water supplies. The disappearance of glaciers also increases the risk of landslides and floods. Another major change is the upward movement of vegetation. As temperatures warm, plants that used to grow at lower altitudes are moving higher up the mountains. This has caused problems for the animals that live in the higher areas. The mountain hare, for instance, relies on its white winter coat to hide from predators. But with less snow cover, it becomes more visible and is easier to catch. The marmot, a rodent that lives in the mountains, is also affected. Warmer temperatures allow its predators to move higher, increasing the pressure on marmot populations. Some birds that breed in the mountains are also arriving earlier in spring and laying eggs sooner. To address these challenges, scientists have set up monitoring stations across mountain ranges. They are tracking changes in temperature, snowfall and vegetation. They are also studying how animals are adapting to the new conditions. The data collected helps governments develop better conservation plans. Many national parks have been established to protect these fragile ecosystems, and visitors are required to follow strict rules to minimize their impact. Part 2: Skills Challenge Task 1: Understand the Story (基础理解) 1. How much of the glacier volume in the Alps has been lost since 1900? A. About a quarter. B. About half. C. About three quarters. D. Nearly all. 2. What problem do mountain hares face as snow cover decreases? A. They cannot find enough food. B. They are more visible to predators. C. They have to move to lower areas. D. They cannot find mates. Task 2: In-depth Comprehension (深层理解) 3. Why does the upward movement of vegetation cause problems for high-altitude animals?   4. What are scientists doing to address the challenges facing mountain ecosystems? (Give two actions.)   Task 3: Express Your Thoughts (表达观点) 5. What else do you think we can do to protect mountain ecosystems besides the methods mentioned in the passage? Use your own thoughts to answer.     参考答案 一、单词默写 1. southeast 2. glacier 3. altitude 4. snowline 5. rocky 6. melt 7. adapt 8. vegetation 9. alpine 10. conserve 二、词组默写 1. lead to 2. adapt to 3. in the daytime 4. set up nature reserves 5. encourage sb. to do sth. 三、根据要求完成句子 1. all year round; for 2. lead to 3. set up; monitor 4. protect / conserve 四、用括号内所给词的适当形式填空 1. led 2. balanced 3.

B 八、思维进阶 Task 1: 1. B 2. B Task 2 (示例): 3. Because plants moving higher reduce the space and food available for high-altitude animals, and it also affects their ability to hide from predators. 4. Scientists are setting up monitoring stations to track changes and studying how animals are adapting to new conditions. Task 3 (示例): 5. We can reduce our carbon footprint by using renewable energy and walking or cycling instead of driving. We can also support organizations that work to protect mountain ecosystems and educate others about the importance of these environments. 学科网（北京）股份有限公司 $
