IV. 阅读理解 Sarah Chen is a 16-year-old student from Shanghai who loves both science and art. Last summer, she joined a volunteer program called “Art & Science for All”. The program aims to bring the beauty of science to children in rural areas through creative art projects. Sarah and her team traveled to a small village in Guizhou. They taught children how to make simple telescopes using cardboard tubes and lenses. “Many kids there had never seen a real telescope before,” Sarah said. “Their eyes lit up when they saw the moon’s craters through the handmade telescope.”▲ Besides teaching, Sarah also learned a lot from the experience. She found that children in rural areas often have unique ways of observing the world. For example, a 10-year-old boy drew a picture of a “space tree” — a tree that grows stars instead of fruits. “His imagination really inspired me,” Sarah laughed. The program lasted for two weeks. Before leaving, Sarah and the children held a small exhibition of their artworks. Local villagers were invited to visit, and many were surprised by the creativity of the children. “This experience made me realize that education is not just about textbooks,” Sarah said. “It’s about opening minds and hearts.” ( ) 16. What was the purpose of the volunteer program “Art & Science for All”? A. To teach children how to draw pictures. B. To sell handmade telescopes to rural schools. C. To introduce science to rural children through art. D. To train volunteers to become professional artists. ( ) 17. 【信息还原】Which of the following can be put in the “▲ ” in Paragraph 2? A. but they found it too difficult to understand B. and they quickly became interested in science C. because the telescopes were very expensive D. so they decided to give up the project ( ) 18. What can we infer from Paragraph 3? A. Rural children lack imagination. B. Sarah learned from the children’s creativity. C. The boy’s “space tree” was drawn by Sarah. D.

This process is mainly caused by the decrease of sunlight and temperature. During spring and summer, leaves produce chlorophyll (叶绿素) — a green pigment (色素) that helps plants make food through photosynthesis (光合作用). As days get shorter in autumn, trees stop producing chlorophyll, and the green color fades away. Then, other pigments like carotenoids (类胡萝卜素) and anthocyanins (花青素) start to show up. Carotenoids create yellow and orange colors, while anthocyanins produce red and purple shades. Interestingly, the exact color of autumn leaves depends on many factors, including temperature, rainfall, and soil conditions. For example, sunny days and cool nights often lead to brighter red leaves. This is because cool nights prevent the sugar produced during the day from moving out of the leaves, and the sugar helps form anthocyanins. In addition to their beauty, falling leaves also play an important role in nature. They decompose (分解) and return nutrients to the soil, providing food for insects and small animals. So next time you see a golden maple leaf, remember that it’s not just a sign of autumn — it’s part of nature’s recycling system. 20. What causes leaves to change color in autumn?
