Millions of monarch butterflies（帝王蝶）begin a long and dangerous journey from Mexico to Canada. This migration is one of the most incredible journeys in the animal world. The butterflies travel up to 4,000 kilometers, crossing mountains, deserts, and lakes. What makes this even more amazing is that the butterflies that start the journey are not the same ones that finish it. It takes three to four generations of butterflies to complete the round trip. However, the monarch butterfly is now in trouble. Over the past 20 years, the number of monarch butterflies has dropped by about 80%. The main reason is the loss of milkweed（乳草）, a plant that monarch caterpillars（幼虫）depend on for food. Farmers have cleared many fields where milkweed used to grow, and the use of chemicals has killed much of what remains. Climate change is another factor. Unusual weather patterns can disrupt the butterflies' migration and reduce their chances of survival. To help save the monarch butterfly, people across North America are taking action. Many schools and families are planting milkweed gardens to provide food for the caterpillars. Scientists are studying the butterflies' migration routes to understand how to better protect them. Some organizations are working with farmers to create butterfly-friendly habitats on farmland. Technology is also playing a role. A smartphone app called "Journey North" allows people to report monarch sightings. This helps scientists track the butterflies' movements and identify important stopover sites. With this information, they can focus protection efforts where they are needed most. As one scientist said, "The monarch butterfly is like a thermometer for our planet. Its health reflects the health of our environment. By saving the monarchs, we are also helping to save ourselves." 26. What is the main purpose of the first paragraph? A. To introduce the life cycle of monarch butterflies. B. To describe the incredible migration of monarch butterflies. C. To explain why monarch butterflies are in danger. D. To compare monarch butterflies with other insects. 27. Which of the following is NOT mentioned as a reason for the decline of monarch butterflies? A. Loss of milkweed. B. Use of chemicals. C. Climate change. D. Hunting by humans. 28. How does the smartphone app "Journey North" help scientists? A. By planting milkweed gardens. B. By tracking the butterflies' movements. C. By stopping farmers from using chemicals. D. By teaching people how to raise butterflies. 29. What does the scientist mean by saying "The monarch butterfly is like a thermometer for our planet"? A. Monarch butterflies can predict the weather. B. The health of monarch butterflies reflects the health of our environment. C. Monarch butterflies are sensitive to temperature changes. D. Scientists use monarch butterflies to measure temperature. Ⅵ. 阅读表达。 Have you ever heard of the "Green Corridor"? It is a special project that connects separated natural habitats with strips of green land. These corridors allow wild animals to move safely from one area to another, find food, and meet other animals to breed. In many parts of the world, roads, cities, and farms have cut through forests and grasslands, dividing animal habitats into small pieces. This makes it difficult for animals to survive. For example, elephants in Africa often have to cross busy roads to find water, which puts them in great danger. The Green Corridor project builds bridges covered with plants over highways and creates tunnels under roads, so animals can pass through without risk. One successful example is in Brazil's Atlantic Forest. There, a Green Corridor has been built to connect two separated parts of the forest. Since the corridor was completed, scientists have noticed that more animals, including rare species like the jaguar, are using it to move between the forests. This helps increase the genetic diversity of the animals, which is important for their long-term survival. Schools in some countries are also getting involved. Students are learning about the importance of wildlife corridors and even helping to plant trees along the corridors. One student said, "It feels great to know that we are helping animals find their way home." The Green Corridor project shows that when humans and nature work together, we can create a better future for all living things. 30. What is the "Green Corridor" project? ____________________________________________________ 31. Why do animals need green corridors? (List at least one reason.) ____________________________________________________ 32. How does the Green Corridor project help elephants in Africa? ____________________________________________________ 33. What happened after the Green Corridor was built in Brazil's Atlantic Forest? ____________________________________________________ 34. What is the writer's purpose of writing this passage? ____________________________________________________ 【参考答案】 Ⅰ. 根据首字母及汉语提示填空。 1. label2. population3. endangered4. worldwide5. vulnerable Ⅱ. 用方框中所给词的正确形式填空。 6. foreign7. environmental8. protect9. survival10.
