我是一只来自加拿大的黑脉金斑蝶！夏天很有趣。我从一朵花飞到另一朵花，从一棵树飞到另一棵树。但到了秋天，生活变得充满挑战。我必须长途南飞，前往墨西哥的黑脉金斑蝶生物圈保护区。现在，天气正在变化。

Understanding ecosystems
◆ Structure of the article ◆
Beginning: Introduce your ecosystem and describe its special features.
Main body Talk about the plants and animals in the ecosystem. Talk about threats to the ecosystem. Use separate paragraphs for different threats.
Ending: Summarize your thoughts about the ecosystem.
B Research some interesting ecosystems in the world and write an article about one of them. You can include information about the plants and animals in the ecosystem and the problems it faces.
The Amazon Rainforest: the lungs of the Earth
One of the world's most amazing ecosystems is the Amazon Rainforest, located in South America. It is the largest rainforest on Earth, with high temperatures and heavy rainfall all year round. This vast area is covered with dense trees, forming a green "roof" that blocks much of the sunlight.
The Amazon Rainforest is home to an incredibly rich variety of plants and animals. There are thousands of tree species, some growing over 60 meters tall. Colorful orchids and bromeliads grow on tree branches. Animals here include jaguars, sloths, monkeys, and countless birds like macaws. The river systems in the rainforest are also home to piranhas and pink dolphins.
However, the Amazon Rainforest faces serious threats. Deforestation is a major problem. People are cutting down trees to make space for farms and roads. Each year, large areas of the rainforest disappear, destroying the homes of many plants and animals.
Another threat is climate change. Rising temperatures and changing rainfall patterns are harming the rainforest. Some areas are becoming drier, making it harder for plants to grow and increasing the risk of wildfires.
The Amazon Rainforest is crucial for our planet, producing much of the world's oxygen. We must work together to protect it, or this wonderful ecosystem will be lost forever.
