Costa Rica: A Pioneer in Green Energy Costa Rica, a small country in Central America, has become a global leader in environmental protection. With its rich rainforests, diverse wildlife, and strong commitment to sustainability, it offers a powerful model for a green future. Unlike many countries that rely heavily on fossil fuels, Costa Rica gets most of its electricity from renewable sources. In fact, for over eight years in the last decade, the country ran on more than 98% renewable energy for more than 300 days each year. The main sources are hydropower (using rivers), geothermal energy (using heat from volcanoes), wind, and solar power. The government has invested heavily in these clean technologies and has set a goal to become completely carbon-neutral (净零碳排放) by 2050. Protecting forests is another key priority. In the 1990s, Costa Rica had one of the highest deforestation rates in the world. To change this, the government started a program called "Payments for Environmental Services". Landowners who protect forests on their property receive money from the government. This program, along with strict laws against illegal logging, has been very successful. Today, over 50% of the country is covered by forests, which are home to nearly 6% of the world's biodiversity. Ecotourism (生态旅游) plays a big role in both the economy and environmental education. Millions of tourists visit each year to see the volcanoes, beaches, and wildlife. Strict rules protect natural areas from being harmed by tourism. Visitors learn about the importance of conservation, and the money from tourism helps fund more environmental projects. Of course, challenges remain. Plastic pollution is still a problem in some areas, and climate change brings more extreme weather. However, Costa Rica shows that with clear goals, strong policies, and public support, a small country can make a huge difference. Its journey reminds us that protecting the planet is not only necessary but also possible. 1. What is the main purpose of the first paragraph? A. To introduce Costa Rica's location and size. B. To describe the wildlife in Costa Rica. C. To explain why Costa Rica is poor. D. To present Costa Rica as a green model. 2. How does the author support the statement that Costa Rica is a leader in green energy? A. By comparing its energy use with other Central American countries. B. By giving examples of its renewable energy sources and specific data. C. By explaining how geothermal energy works in detail. D. By describing the daily life of people in Costa Rica. 3. What was the main reason for the great increase in forest coverage in Costa Rica? A. The weather changed and became perfect for trees to grow. B. The government paid landowners to protect forests and made strict laws. C. All the farmers moved to cities and stopped cutting trees. D. International organizations planted millions of trees for free. 4. What is the biggest challenge Costa Rica faces now according to the passage? A. Not having enough tourists. B. Running out of geothermal energy. C. Plastic pollution and climate change. D. High unemployment rate. 5. What can we learn from Costa Rica's story? A. Only rich countries can protect the environment well. B. Environmental protection can be achieved with clear goals and efforts. C. Tourism always harms the environment. D. Small countries do not need to worry about climate change. 练习答案 1、 1-2 C C 2、 1. made strict laws 2. depend on natural resources 3. produce little pollution and will never run out 3、 （参考答案）Because we depend on its rich resources to live, and it provides us with clean air, water, and beautiful places. 4、 1. D 解析：主旨题。第一段的核心句是最后一句：“...it offers a powerful model for a green future.”（它为一个绿色的未来提供了一个强有力的榜样。）这与D选项“将哥斯达黎加呈现为一个绿色榜样”意思一致。A、B选项是细节，C选项文中未提及。 2. B 解析：细节理解/论证方式题。第二段为了证明哥斯达黎加是绿色能源领导者，首先指出其大部分电力来自可再生能源，然后列举了具体能源类型（hydropower, geothermal, wind, solar），并给出了具体数据（超过98%，超过300天）。B选项准确概括了这种方法。A、C选项过于片面或细节，D选项未提及。 3. B 解析：细节题。第三段明确说明了森林覆盖率增长的原因：政府启动了“环境服务付费”项目（给保护森林的土地所有者钱）并制定了反对非法伐木的严格法律。B选项是这两点的同义转述。A、D选项文中未提及，C选项与事实不符（农民并未全部搬走）。 4. C 解析：细节题。最后一段开头明确写道：“Of course, challenges remain. Plastic pollution is still a problem..., and climate change brings more extreme weather.” C选项直接对应原文。A、B、D选项均未在文中作为当前主要挑战被提及。 5. B 解析：推理判断题。文章通篇讲述哥斯达黎加通过设定目标（如2050碳中和）、制定政策（付费护林、严格法律）、发展生态旅游等努力取得了环保成效。最后一段总结：“Its journey reminds us that protecting the planet is not only necessary but also possible.” 这强烈支持B选项的推断。A、C选项的表述过于绝对且与文意不符，D选项与文章主旨相反。 学科网（北京）股份有限公司 $
