B In 2026, scientists around the world made some amazing discoveries about nature. Here are three of them. Discovery 1: A new bird species in Indonesia Scientists found a new kind of bird on a small island in Indonesia. The bird has bright blue feathers and a long tail. It sings a very special song. “We have never seen this bird before,” said Dr. Sari, a biologist. “This shows there is still so much we don’t know about our planet.” Discovery 2: Plants can “hear” water A study from the University of Western Australia found that plants can hear the sound of flowing water. Scientists put pea plants in pots. One pot had a pipe with flowing water inside. The plants grew their roots toward the pipe. “Plants are smarter than we thought,” said one scientist. Discovery 3: Dolphins call each other by name Researchers have known for a long time that dolphins are smart. But a new study shows that dolphins call each other by special sounds. Each dolphin has its own “name”. When another dolphin calls its name, it answers. This is similar to how humans use names! These discoveries remind us that nature is full of wonders. Every year, scientists find new things that change our understanding of the world. 根据短文内容，选择最佳答案。 31. Where did scientists find the new bird species? A. In Australia. B. In Indonesia. C. In China. D. In America. 32. What did the pea plants do when they heard flowing water? A. They grew taller. B. They grew more leaves. C. They stopped growing. D. They grew their roots toward the water. 33. How do dolphins call each other? A. By making loud noises. B. By jumping out of water. C. By using special sounds like names. D. By swimming together. 34. What does the discovery about plants tell us? A. Plants are smarter than we thought. B. Plants are not living things. C. Plants cannot survive without water. D. Plants only grow in wet places. 35. What is the main idea of the passage? A. Scientists are working hard to protect nature. B. Nature is full of wonders and we still have much to learn. C. Dolphins are the smartest animals in the world. D. Indonesia has many kinds of birds. C Do you love nature? Do you want to help scientists make discoveries? You can become a citizen scientist (公民科学家). A citizen scientist is an ordinary person who helps collect data for scientific research. Here’s how you can start. Step 1: Observe the nature around you You don’t need to go to the rainforest or the deep sea. Start in your own backyard. Watch the birds that visit your garden. Count how many butterflies you see. Take photos of interesting plants. Every observation (观察) is useful. Step 2: Join a citizen science project Many websites and apps connect citizen scientists with real research projects. For example, you can help scientists count birds in your area. You can report the weather changes you see. Some projects even use photos taken by ordinary people to track animal movements. Step 3: Record and share your findings Write down what you see. Take clear photos. Then share your data on the project’s website. Your small contribution can help scientists understand big problems like climate change and habitat loss. Real success stories from 2025 show that citizen scientists helped discover two new insect species in China. “Without their help, we might have missed these discoveries,” said Dr. Zhang, a biologist. So, start observing today. You never know what you might discover! 根据短文内容，回答下列问题。 36. What is a citizen scientist? __________________________________________ 37.

They spend most of their time eating bamboo. Thanks to protection efforts, the number of pandas has increased from 1,600 in 2010 to about 1,900 in 2026. They are no longer endangered. People have built nature reserves and stopped hunting. However, we still need to protect their forests. Every small action helps. Have you seen a panda before? Please write to me. Yours, Li Hua 高分句式： I’d like to tell you about... They live in / have / spend... Thanks to protection efforts, the number has increased... They are no longer endangered. People have built... and stopped... However, we still need to... Every small action helps. Have you seen... before? 学科网（北京）股份有限公司 $
