A male fox is called a dog, while a female fox is known as a vixen. Foxes have excellent hearing. They can hear sounds as quiet as a watch ticking from 30 meters away! This is like hearing someone whisper from across a playground. In addition to their great hearing, foxes can run very fast. They can reach speeds of up to 30 miles per hour, which is quite impressive. Foxes are carnivores, meaning they mainly eat meat. However, they also enjoy berries from bushes and will often search through rubbish bins for leftovers. Baby foxes, called kits, drink milk from their mothers before they start eating other foods like worms. Foxes are also known to hide food to eat later. Foxes can be found in various habitats. They live in dens in the countryside with other foxes, but they also make their homes in towns and cities. You might see one if you are out on a dark night. Foxes are mammals, which means they have warm blood and fur. Although they are nocturnal (active at night), they can sometimes be seen during the day. They enjoy sunbathing in warm places. 24. How far can foxes hear sounds? A. 30 meters. B. 30 kilometers. C. 30 miles. D. 30 centimeters. 25. What do baby foxes drink before they start eating other foods? A. Water. B. Milk. C. Juice. D. Soup. 26. Where do foxes mainly live? A. Ocean. B. Desert. C. Mountains. D. Countryside and cities. 27. In which part of a magazine can you probably read this passage? A. Art B. Sports C. Animals D. History C China’s Beijing Library was named Public Library of the Year at an awards ceremony on 7 October in Barcelona, Spain. The library was one of four finalists in the annual competition, which is judged by the International Federation of Library Associations and Institutions (IFLA). The IFLA judges said the Beijing Library had a “surprising factor”. They praised the way the building’s design connects books, people, and nature, and were also pleased with how eco-friendly it is, which means it causes little or no damage to the environment and is made to last a long time. The library, which opened in December 2023, was designed by builders from China and Norway. It houses the world’s largest temperature-controlled reading space, which is 75,000 square meters. It has huge windows and tall columns topped with flat panels, which are shaped to look like the leaves of a ginkgo tree—the national tree of China. The building can collect rainwater to reuse and has solar panels built into its roof so that it can create energy from the sun. Inside and outside the library are rounded terraces (different levels), which are designed to fit in with the hills and valleys of the surrounding area. The judges said the library “shows its connection to the environment through its nature-based design”. 28. What did the judges mean by saying the library has a “surprising factor”? A. It has a glass roof. B. It has a big garden on the roof. C. It has a tall tower. D. It looks like a leaf from a tree. 29. What is one special thing about the design of the Beijing Library? A.

D On October 9, 2023, 18-year-old Nima Rinji Sherpa made history by becoming the youngest person to climb all 14 of the world’s 8,000-meter-high mountains. He reached the top of Mount Shishapangma in China’s Xizang region early in the morning at 6:05 AM local time, with Mount Shishapangma standing at 8.027 meters high. With this achievement, Nima went beyond his uncle, Mingma Gyabu Sherpa, who held the record at the age of 30 in 2019. Nima’s father, Tashi Lakpa Sherpa, is also famous for being the youngest to climb Mount Everest without oxygen at just 19 years old. Nima began his climbing journey at 16 and made his first appearance on September 30, 2022, with Mount Manaslu, the eighth-highest mountain. Over the past two years, he has broken several records, including reaching the top of nine 8,000-meter peaks in 2023 alone. Nima’s goal is part of his “SherpaPower” plan. He wants to change how people think about Sherpas, showing they can be great athletes and adventurers, not just guides. “Sherpas are strong, can manage hard times, and love what they do, Nima said.” “We can be the best, not just guides.” He gives his achievements to his parents and his project, and encourages younger Sherpas to dream big and break free from fixed ideas. In 1986, an Italian climber named Reinhold Messner became the first to climb all 14 peaks without oxygen when he was 42. Nima’s achievement is wonderful. Nima’s journey shows ________, encouraging others to see the possibilities that lie ahead. 32. How did Nima make history? A. By breaking his uncle’s record in climbing. B. By reaching the top of Mount Shishapangma. C. By climbing Mount Everest without oxygen. D. By becoming the youngest to climb all 14 peaks. 33. What is Nima’s “SherpaPower” plan about? A. To encourage more people to climb mountains. B. To teach more climbing skills to younger people. C. To change how people regard Sherpas as sports people. D. To encourage climbing competitions for young Sherpas. 34. Which sentence can be put in the ________? A. Hard work and effort lead to success. B. Anyone can achieve greatness beyond being guides. C. Anyone can climb mountains if they try hard enough. D. Young climbers should always look for new challenges. 35. What is the best title for this passage? A. Nima Sherpa: A New Climbing Hero B. The Journey of a Young Climber C. The Power of Effort in Climbing D. Achievements of Young Sportspeople E ①Take a moment to pay attention to your body. Notice your breathing—is it fast, slow, or somewhere in between? Are your thoughts racing, or are you focused on what you are reading? These feelings are signals from your body and brain, showing how you feel right now. ②So, where do feelings come from? According to Ekta Hattangady, a counselor, feelings start in our brains but also show up in our bodies. For example, when we are happy, we smile. If we are surprised, we might feel tightness in our throat or chest. When we are scared, our breathing can become quick and shallow. ③Understanding why feelings are important and necessary. Hattangady explains that emotions (情感) give us signs about what we need. For example, feeling angry might mean something is unfair and needs to be fixed. If you feel sad, it could mean you need comfort or time to fix. Recognizing and naming your feelings is called emotional awareness (意识), which is an important part of growing up. This awareness helps you talk about your feelings and ask for help when needed. ④Emotions can be seen as messengers. In the movie “Inside Out”, the characters in 13-year-old Riley’s mind are the signs of her feelings. As Riley faces big changes, these feelings take charge. Joy, fear, and sadness all play important roles when she starts a new school and worries about losing friends. Riley learns that all feelings are normal and have important jobs in our lives. ⑤To build emotional awareness, try to notice how you feel throughout your day. Hattangady suggests that feelings come and go. By learning to notice them without letting them control you, we can stay calm and make better choices. ⑥In a word, recognizing and understanding our feelings is important for our emotional health. By paying attention to our feelings, we can better deal with our emotions and reply to our needs. 36. Why is it important to recognize our feelings? A. Because it makes us feel much happier. B. Because it allows us to understand our needs. C. Because it helps us to avoid many problems. D. Because it helps us pay no attention to our emotions. 37. How does the writer explain the idea of emotional awareness? A. By providing examples from movies B. By explaining the effects of emotions C. By sharing personal experiences D. By listing different types of feelings 38. Which of the following best matches the information in the passage? A. All feelings are negative and harmful. B. Emotional awareness is only for children. C. Emotions can guide us in making choices. D. Feelings are unimportant and should be ignored. 39. Which of the following shows the structure of this passage? A. B. C. D. V.口语应用。（每小题1分，共5分） 阅读下面对话，从7个选项中选择5个恰当的句子完成此对话，并把答题卡上对应题目的答案标号涂黑。 A: The winter vacation is coming. What’s your plan?

In the old days, we used to set off fireworks and watch the Spring Festival Gala on TV. But now, things are different. We don’t set off fireworks much anymore because we want to protect the environment. Instead, we play games on our phones and chat with our family and friends online. The food we eat during the Spring Festival has also changed. We still eat dumplings and fish, which are symbols of good luck, but we also try different kinds of food from all over the world. I think these changes show how our lives are getting better and more colorful. Even though some old ways are gone, I like the new ways because they make the Spring Festival more fun and interesting. It’s a time to remember our traditions and also to enjoy the new things that come with the modern world. 第1页/共1页 学科网（北京）股份有限公司 $$
