They have black-and-white fur, round bodies and big black eye patches—like soft teddy bears. Most pandas live in the bamboo forests of Sichuan, China. What makes pandas special? They love bamboo more than anything else. An adult panda eats 12-38 kg of bamboo every day. They spend 10-16 hours eating, and the rest of the time sleeping in trees. Pandas are good at climbing, even though they look heavy. Pandas are important too. They are a symbol of China and help people from different countries know more about China. Also, studying pandas helps scientists learn how animals adapt to cold forests. But pandas face problems: their bamboo forests are getting smaller, so some pandas can’t find enough food. To save pandas, we plant more bamboo and build nature reserves. ( )21. What do pandas look like? A. They have brown fur B. They have big black eye patches C. They have thin bodies D.

That’s why people call it a “living fossil”. Chinese people love this tree; it stands for hope and long life. Ginkgo trees have special leaves. They are fan-shaped. In spring, leaves turn green; in autumn, they become bright yellow. The whole tree looks like a golden umbrella. Many people take photos of ginkgo trees in autumn. Ginkgo trees are useful too. Their leaves can make traditional medicine. Their wood is hard, so people use it to make furniture. What’s more, ginkgo trees live long—some are over 1,000 years old! Today, we plant ginkgo trees in parks and streets. They clean the air and make our cities beautiful. We must protect these “living fossils” for our children. ( )26.
