She saw a beautiful butterfly with colorful wings stuck in a spider web. The butterfly was struggling hard to get free, but the web was too tight. Lily felt sorry for it and wanted to help. She carefully walked over and tried to pull the butterfly out of the web. But as soon as she touched the web, the butterfly struggled more. Just then, her grandma came over and stopped her. “Don’t pull it,” grandma said softly. “The butterfly needs to struggle by itself to get free. If you help it, its wings will become weak, and it won’t be able to fly again.” Lily listened to her grandma and watched the butterfly. The butterfly kept struggling, and little by little, it broke free from the web. It shook its wings and flew into the sky, dancing beautifully in the sun. Lily smiled happily and realized that every living thing in nature has its own way to grow and survive. From that day on, Lily paid more attention to the small things in nature.

Many people wonder how rainbows form and why they have such bright colors. Rainbows form when sunlight passes through water droplets in the air. The sunlight is made up of seven different colors: red, orange, yellow, green, blue, indigo and violet. When the sunlight hits the water droplets, it bends and splits into these seven colors. This process is called refraction. The colors appear in a fixed order, with red on the top and violet on the bottom. You can only see a rainbow when the sun is behind you and the rain is in front of you. Rainbows are usually semicircular, but if you are high up, like on a mountain or in an airplane, you might see a full circle rainbow. Rainbows are not physical objects; they are just light reflections that our eyes can see. Rainbows have been a symbol of hope and happiness in many cultures. They remind us of the beauty of nature and the magic of the world around us. Even though rainbows don’t last long, they leave a deep impression on everyone who sees them. 32. When does a rainbow usually appear? A. Before rain. B. During rain. C. After rain when the sun comes out. D. On a sunny day without rain. 33. How many colors does sunlight consist of? A. Five. B. Six. C. Seven. D. Eight. 34. What is the main idea of this passage? A. How rainbows form and their meaning. B. The colors of rainbows. C. Where to see rainbows. D. The symbol of rainbows. 35. What can we infer from the passage? A. Rainbows are physical objects we can touch. B. We can see a full circle rainbow anywhere. C. Rainbows are a symbol of hope in many cultures. D. Rainbows last for a long time. D篇 The Amazon Rainforest is one of the greatest wonders of nature on Earth. It covers a large area in South America and is home to millions of plants and animals. Many people call it the “lungs of the Earth” because it produces about 20% of the world’s oxygen. The Amazon Rainforest has more plant and animal species than any other place on Earth. There are thousands of different trees, flowers and plants, many of which have medicinal value. Some plants can be used to treat diseases, and scientists are still discovering new uses for them. The rainforest is also home to many rare animals, such as jaguars, sloths and macaws. The rainforest’s climate is hot and wet all year round, which is perfect for plant growth. The thick trees form a canopy that blocks most of the sunlight from reaching the ground. This creates a special environment where many unique plants and animals live. However, the Amazon Rainforest is facing serious threats. Deforestation, caused by human activities like cutting down trees and farming, is destroying large parts of the rainforest. Protecting the Amazon Rainforest is very important for the whole world, as it provides oxygen and helps regulate the Earth’s climate. 36. What is the Amazon Rainforest called? A. The “heart of the Earth”. B. The “lungs of the Earth”. C. The “treasure of the Earth”. D. The “home of the Earth”. 37. Why is the Amazon Rainforest important? A. It produces a lot of oxygen. B.
