These changes are not only about material life, but also about people’s lifestyles and ideas. Thanks to social progress, ordinary people are living a richer and more convenient life than before. In the 1990s, most families lived in small houses with simple furniture. People mainly walked or rode bicycles to go out. It usually took hours to travel to nearby cities. When people missed their relatives in other places, they could only write letters or make expensive long-distance calls. Nowadays, the situation has changed completely. Most families have moved into bright and spacious apartments. Private cars and high-speed railways make travel fast and comfortable. Smart phones have greatly changed people’s communication ways. We can chat, make video calls and share moments with others anytime and anywhere. Short-distance travel, online payment and shared bikes have become common in daily life. All these small changes show the rapid development of our country and bring great happiness to people. 根据短文内容，选择最佳答案。 1. What does the underlined word “spacious” mean in Paragraph 3?

Local temperature and soil are perfect for planting high-quality coffee beans. Villagers first grew coffee trees in 1952. Back then, few Chinese people drank coffee, so villagers stopped coffee planting and grew rice and corn instead. In the 1980s, international coffee brands entered China, and villagers restarted coffee farming. But foreign companies only bought low-grade beans to make cheap instant coffee. Villagers could hardly make enough money to live. Since 2007, the village has upgraded its coffee industry. Farmers started growing high-quality beans and created their own local coffee brand. Today, coffee plantations cover over 9 million square meters. “Baoshan coffee” has won many international awards and sells worldwide. The village also developed rural tourism. A coffee experience hall, coffee museum and farm stays were built. Around 120,000 tourists come to Xinzhai every year. The village has changed from a poor farming area into a famous coffee tourist spot. 1. Why does Xinzhai Village suit coffee planting? A．It has a long farming history. B．International companies give support. C．Lots of tourists come here every year. D．It has proper temperature and soil. 2. Why did villagers stop growing coffee in the 1950s?

Before then, the only transport links between Mombasa, Kenya’s main port, and Nairobi, Kenya’s capital, were rough roads and an old railway line completed in 1901. The old trains were very slow. It took 10 hours to get to Nairobi from Mombasa by train. However, the new railway, built with China’s help, has already cut the travel time between Mombasa and Nairobi to about five hours for passengers. Now, more than two million people use it every year. Local Kenyans have benefited a lot from the new railway. A government worker said, “I’m very happy with the new railway built by our Chinese friends. Many changes have taken place in the town over the last few years, and the people who live here have become rich.” A businessman said, “My experience of using the train since 2017 has been good. It is very convenient and doesn’t cost much money. I am able to get to places on time and make business deals with ease.” The railway has also made the transport of food easier. “It used to take hundreds of lorries to carry food between the two cities, but now it takes only two or three trains,” said a supermarket manager. As a result, people now have more fresh food to eat. Although China and Kenya are far away from each other, the railway shows how different countries can work together to build a better world. 1.

A 【导语】本文介绍线上学习普及的背景、线上学习的优势、存在的难题以及未来线上线下结合的教育模式。 【详解】1. 根据第一段“The COVID-19 pandemic accelerated this shift, forcing schools and universities around the world to move their classes online.”可知，新冠疫情加速了向线上学习的转变。 2. 根据第二段“It allows students to learn at their own pace, review recorded lessons, and access materials from anywhere.”可知，文中提到线上学习的好处之一是学生可以按照自己的节奏学习。 3. 根据第三段“One of the biggest issues is the lack of face-to-face interaction. Students miss the social aspect of learning”可知，线上学习的一大难题是缺少社交互动。 4. 根据第四段“combining online and in-person instruction”，这个模式结合线上与线下授课，由此可推断hybrid意为“混合的”。 5. 第①段引出线上学习普及这一话题；第②段讲优势，第③段讲挑战；第④段展望未来混合式教育，结构为①—②③—④。 Passage 6 China’s high-speed railway network has grown rapidly over the past 15 years. It is now the largest in the world, covering over 45,000 kilometers. The development of high-speed rail has greatly changed the way Chinese people travel. Before the high-speed rail era, it took more than 10 hours to travel from Beijing to Shanghai by train. Now, the high-speed train covers the distance in about 4.5 hours. This has made business trips and family visits much easier and faster. The high-speed railway has also brought economic benefits to many cities. For example, small cities along the railway lines have seen a rapid growth in tourism. More people are willing to visit these places because they can get there quickly and comfortably. However, building such a large railway network was not easy. Engineers had to solve many difficult problems, especially in mountain areas where they needed to build many bridges and tunnels. Despite these challenges, China has successfully built one of the most advanced railway systems in the world. The government plans to continue expanding the high-speed railway network in the coming years, connecting more cities and making travel even more convenient for everyone. 1.

The underlined word “advanced” in Paragraph 4 probably means ________. A．old-fashioned B．expensive C．highly developed D．simple 5. What can we learn about the future of China’s high-speed railway? A．It will stop expanding because it’s already large enough. B．It will continue to grow and connect more cities. C．It will only focus on repairing old railways. D．It will become less popular among travelers. 【答案】1. A 2. B 3. D 4. C 5. B 【导语】本文是一篇说明文，主要讲述了中国高速铁路网络在过去15年间迅速发展，总里程已超过45,000公里，对国人出行方式产生了深远影响；同时介绍了高铁带来的经济效益（带动沿线小城市旅游业）、修建过程中的挑战（山区建桥挖隧道）以及未来的扩展计划。 【详解】1. 根据第二段的“Before the high-speed rail era, it took more than 10 hours to travel from Beijing to Shanghai by train. Now, the high-speed train covers the distance in about 4.5 hours”可知，对比现在高铁仅需约4.5小时。 2. 根据第三段的“small cities along the railway lines have seen a rapid growth in tourism”可知，高铁沿线小城市旅游业快速增长。 3. 根据第四段的“Engineers had to solve many difficult problems, especially in mountain areas where they needed to build many bridges and tunnels”可知，在山区修建众多桥梁和隧道是困难所在。 4. 根据第四段的“China has successfully built one of the most advanced railway systems in the world”可知，advanced修饰railway systems。结合语境“successfully built”（成功建成）与上句克服“challenges”作对比，应理解为“高度发达的”。 5. 根据最后一段的“The government plans to continue expanding the high-speed railway network in the coming years, connecting more cities and making travel even more convenient for everyone”可知，政府计划继续扩展高铁网络、连接更多城市。 Passage 7 Sixty years ago, Saihanba was a wide sandy wasteland with almost no tall trees. Strong sandstorms hit this area all year round. Local farmers could only grow little corn on poor soil, and their daily lives were extremely hard. In 1962, with full support from the local government, a group of young forest workers moved to this cold barren land. They made up their minds to plant trees to hold soil and stop terrible sandstorms. At the very beginning, most young saplings died because of freezing winters and thin sandy earth. But the workers never gave up their long-term goal. Year after year, they kept planting bushes and different kinds of trees. Up till now, millions of trees have been grown here, forming the world’s largest man-made forest. Now Saihanba looks totally different. Heavy sandstorms have almost disappeared. Large areas of fruit crops grow well on rich soil. Every year hundreds of tourists come to visit the forest park, and local villagers sell handmade crafts and fresh fruits to visitors. Many young people who once left for big cities have returned to run small local businesses. People all call this amazing environmental change a miracle created by sixty years of hard work. 1.

A．Sandstorms rarely break out here. B．Lots of young villagers come back to start businesses. C．Millions of trees have been planted on the wasteland. D．Farmers still cannot grow any fruit crops on the land. 5. What is the main idea of this article? A．The huge environmental and living changes in Saihanba after 60 years’ hard work. B．Detailed steps of planting trees on cold sandy land. C．Different kinds of fruits grown in Saihanba forest farms. D．Travel rules and ticket standards of Saihanba park. 【答案】1. B 2. B 3. B 4. D 5. A 【导语】本文主要讲述了塞罕坝在60年艰苦奋斗下，从荒漠变成绿洲，环境和生活都发生了巨大改变。 【详解】1. 首段第一句“Sixty years ago, Saihanba was a wide sandy wasteland with almost no tall trees”明确提到六十年前，塞罕坝是一片广阔的沙地荒原，几乎没有树木。 2. 第一段结尾句“They made up their minds to plant trees to hold soil and stop terrible sandstorms”明确提到一群年轻林业工人来到塞罕坝是为了种树防风固沙。 3. 划线词所在句子为“People all call this amazing environmental change a miracle created by sixty years of hard work”，其中“amazing environmental change”意为“惊人的环境变化”对应划线词miracle，miracle表示“奇迹”与“surprising great wonder”同义。 4. 第三段提到“Large areas of fruit crops grow well on rich soil”以及“and local villagers sell handmade crafts and fresh fruits to visitors”，说明如今塞罕坝可以种植水果，D表述完全与原文相反。 5. 全文以时间线讲述了塞罕坝60年艰苦奋斗，从荒漠变成绿洲，环境和生活都发生了巨大改变。 Passage 8 DeepSeek is amazing in the AI world. On January 20th, 2025, Chinese AI company DeepSeek made its latest AI model, DeepSeek-R1 come out, which took the AI world by surprise. The model can perform the same tasks as other top models, but at a lower cost. Unlike other AI models, DeepSeek-R1 is free to use, making it easy for developers to study and build upon. DeepSeek-R1 is very good at tasks that need logical inference (逻辑推理) and real-time decision-making. Whether it’s solving difficult maths problems or breaking down other scientific questions, DeepSeek-R1’s special system allows it to improve its thinking and problem-solving abilities over time. On its first day online, over 19,000 programmers started projects to study it and most thought highly of it. Even a top scientist from Meta (a famous US tech company) praised it, saying, “This kind of free AI could change the world.” The rise of DeepSeek has also brought its founder, Liang Wenfeng, into the spotlight (聚光灯). Born in 1985 in a small town in Guangdong Province, Liang was greatly influenced by his parents who were both primary school teachers. Even though there was little information, Liang showed an amazing talent for maths and a great love for technology from a young age. In university, he developed a strong interest in machine learning, which was helpful for his future achievements. In 2023, Liang founded DeepSeek in Hangzhou. He has put together a talented team. So far, they’ve developed several AI models. DeepSeek is changing the AI industry. It proves that China isn’t just catching up with the West in technology—it’s setting new rules for the game. 1.

Yet by high school, only a small percentage achieve fluency. What makes the difference? A recent report from the Educational Testing Service identified three key factors that predict success: consistent exposure, active usage, and emotional connection. Consistent exposure means more than sitting in a classroom. Top learners surround themselves with the language—they change their phone settings, listen to English podcasts during commutes, and read news in English daily. This constant immersion trains the ear to recognize speech patterns naturally. One 16-year-old from Beijing reported that after watching every episode of a popular American sitcom three times, she no longer needed Chinese subtitles. Active usage pushes learners beyond passive reception. Instead of consuming content, they produce it—writing journals, recording voice memos, or participating in online debates. A study from the University of Cambridge showed that students who practiced speaking for at least 15 minutes daily improved their oral fluency 3 times faster than those who only listened. Importantly, these learners weren’t afraid of sounding imperfect; they embraced the discomfort of not knowing every word. The third factor, emotional connection, is often ignored. Students who link English to personal passions—gaming, music, or even cooking videos—develop deeper motivation. Take 14-year-old Maria from Mexico, who learned English by translating her favorite pop songs. “I didn’t feel like I was studying,” she says. “I was unlocking lyrics I loved.” This positive association turns a challenging task into a rewarding hobby, making persistence feel effortless. 根据短文内容，选择最佳答案。 1. According to the passage, how many students achieve English fluency? A．Most students do. B．About half of them. C．Only a small number. D．Almost all students. 2. What did the 16-year-old from Beijing do to improve her English? A．She traveled to an English-speaking country. B．She watched a sitcom repeatedly until she understood it well. C．She took extra classes after school every day. D．She practiced speaking English for 15 minutes daily. 3. What does the University of Cambridge study suggest about speaking practice? A．Listening alone is more effective than speaking. B．Daily speaking practice significantly improves oral fluency. C．Speaking practice only helps advanced learners. D．15 minutes of speaking weekly is sufficient. 4. How did Maria from Mexico learn English? A．By attending a language school. B．By translating her favorite songs. C．By reading English novels. D．By practicing with native speakers. 5. What is the author’s main purpose in writing this passage? A．To show that learning English is impossible for most students. B．To recommend three effective strategies for language learning. C．To prove that emotional connection is the only factor that matters.

Before its birth, the only transport ways connecting Kisumu, Uganda’s main lake port, and Eldoret, Kenya’s inland capital city, were bumpy country roads and an old railway track built in 1905. The outdated trains ran at a very low speed. It would take 11 hours to travel from Kisumu to Eldoret by the old train. Luckily, this new railway built with Chinese aid has already shortened the passenger travel time between the two cities to nearly three hours. At present, more than 1.8 million passengers take this railway every single year. Local Ugandan residents gain plenty of advantages from this new railway. A local civil servant shared, “I’m really satisfied with the railway built by our Chinese partners. Great changes have taken place in our small town these years, and all the villagers here live a wealthier life.” A local trader added, “I’ve taken this new train many times since 2019, and the experience is wonderful. It’s cheap and super convenient. I can reach business sites on schedule and finish trade deals without trouble.” The railway also makes transporting fresh food much easier. A market manager said, “In the past, we needed hundreds of trucks to carry fruit and vegetables between the two cities, but now only two or three train carriages can finish the job.” Thanks to this railway, locals can eat more fresh farm food every day. Even though China and Uganda are thousands of miles apart, this railway fully shows that different nations can cooperate closely to build a better shared world. 根据短文内容，选择最佳答案。 1.

Before this new railway appeared, local people could only choose old slow trains or rough muddy dirt roads. It took nearly ten hours to travel from Mombasa Port to Nairobi, the country’s capital city. Since the railway opened to passengers, great positive changes have taken place across Kenya. The travel time between the two cities is cut down to only about four hours. Local businessmen can send fruits, grains and daily goods by train with much lower transport costs. More foreign tourists take the railway to visit wild animal reserves, so local hotels and souvenir shops gain more customers every year. Local government officials interviewed by newspapers said small towns along the railway have developed rapidly over the past nine years.

Local temperature and soil are perfect for planting high-quality coffee beans. Villagers first grew coffee trees in 1952. Back then, few Chinese people drank coffee, so villagers stopped coffee planting and grew rice and corn instead. In the 1980s, international coffee brands entered China, and villagers restarted coffee farming. But foreign companies only bought low-grade beans to make cheap instant coffee. Villagers could hardly make enough money to live. Since 2007, the village has upgraded its coffee industry. Farmers started growing high-quality beans and created their own local coffee brand. Today, coffee plantations cover over 9 million square meters. “Baoshan coffee” has won many international awards and sells worldwide. The village also developed rural tourism. A coffee experience hall, coffee museum and farm stays were built. Around 120,000 tourists come to Xinzhai every year. The village has changed from a poor farming area into a famous coffee tourist spot. 1. Why does Xinzhai Village suit coffee planting? A．It has a long farming history. B．International companies give support. C．Lots of tourists come here every year. D．It has proper temperature and soil. 2. Why did villagers stop growing coffee in the 1950s?

Before then, the only transport links between Mombasa, Kenya’s main port, and Nairobi, Kenya’s capital, were rough roads and an old railway line completed in 1901. The old trains were very slow. It took 10 hours to get to Nairobi from Mombasa by train. However, the new railway, built with China’s help, has already cut the travel time between Mombasa and Nairobi to about five hours for passengers. Now, more than two million people use it every year. Local Kenyans have benefited a lot from the new railway. A government worker said, “I’m very happy with the new railway built by our Chinese friends. Many changes have taken place in the town over the last few years, and the people who live here have become rich.” A businessman said, “My experience of using the train since 2017 has been good. It is very convenient and doesn’t cost much money. I am able to get to places on time and make business deals with ease.” The railway has also made the transport of food easier. “It used to take hundreds of lorries to carry food between the two cities, but now it takes only two or three trains,” said a supermarket manager. As a result, people now have more fresh food to eat. Although China and Kenya are far away from each other, the railway shows how different countries can work together to build a better world. 1.

Ten years ago, few people had a smartphone. Now, almost everyone has one, even teenagers and elderly people. Smartphones allow us to keep in touch with others easily. We can make calls, send messages, and video chat with friends and family no matter where they are. We can also use them to take photos and videos, share them on social media, and even edit them with special apps. Besides communication, smartphones are also used for work and study. Many people use them to check emails, work on documents, and attend online meetings. Students can use them to look up information, take notes, and even take online courses. However, smartphones also bring some problems. Some people spend too much time on them, which affects their study, work, and health. They may also face problems like eye strain and sleep loss.

Passage 5 ① In the past decade, online learning has changed from a niche option to a mainstream method of education. The COVID-19 pandemic accelerated this shift, forcing schools and universities around the world to move their classes online. ② Many students and teachers have found that online learning has some clear benefits. It allows students to learn at their own pace, review recorded lessons, and access materials from anywhere. It also gives students more flexibility to balance their studies with other activities. For teachers, online platforms can make it easier to track student progress and provide personalized feedback. ③ However, online learning also has its challenges. One of the biggest issues is the lack of face-to-face interaction. Students miss the social aspect of learning — the group discussions, the spontaneous questions, and the encouragement from classmates. Additionally, not all students have equal access to reliable internet or quiet study spaces, which can create inequalities. ④ Despite these challenges, many experts believe that online learning is here to stay. They predict that the future of education will be a hybrid model, combining online and in-person instruction. This way, students can enjoy the best of both worlds. 1.

The development of high-speed rail has greatly changed the way Chinese people travel. Before the high-speed rail era, it took more than 10 hours to travel from Beijing to Shanghai by train. Now, the high-speed train covers the distance in about 4.5 hours. This has made business trips and family visits much easier and faster. The high-speed railway has also brought economic benefits to many cities. For example, small cities along the railway lines have seen a rapid growth in tourism. More people are willing to visit these places because they can get there quickly and comfortably. However, building such a large railway network was not easy. Engineers had to solve many difficult problems, especially in mountain areas where they needed to build many bridges and tunnels. Despite these challenges, China has successfully built one of the most advanced railway systems in the world. The government plans to continue expanding the high-speed railway network in the coming years, connecting more cities and making travel even more convenient for everyone. 1. How long does it take to travel from Beijing to Shanghai by high-speed train now? A．About 4.5 hours. B．About 6 hours. C．About 10 hours. D．About 15 hours. 2. What benefit has the high-speed railway brought to small cities? A．More factories. B．More tourists. C．More schools. D．More hospitals. 3.

The underlined word “advanced” in Paragraph 4 probably means ________. A．old-fashioned B．expensive C．highly developed D．simple 5. What can we learn about the future of China’s high-speed railway? A．It will stop expanding because it’s already large enough. B．It will continue to grow and connect more cities. C．It will only focus on repairing old railways. D．It will become less popular among travelers. Passage 7 Sixty years ago, Saihanba was a wide sandy wasteland with almost no tall trees. Strong sandstorms hit this area all year round. Local farmers could only grow little corn on poor soil, and their daily lives were extremely hard. In 1962, with full support from the local government, a group of young forest workers moved to this cold barren land. They made up their minds to plant trees to hold soil and stop terrible sandstorms. At the very beginning, most young saplings died because of freezing winters and thin sandy earth. But the workers never gave up their long-term goal. Year after year, they kept planting bushes and different kinds of trees. Up till now, millions of trees have been grown here, forming the world’s largest man-made forest. Now Saihanba looks totally different. Heavy sandstorms have almost disappeared. Large areas of fruit crops grow well on rich soil. Every year hundreds of tourists come to visit the forest park, and local villagers sell handmade crafts and fresh fruits to visitors. Many young people who once left for big cities have returned to run small local businesses. People all call this amazing environmental change a miracle created by sixty years of hard work. 1.

Passage 8 DeepSeek is amazing in the AI world. On January 20th, 2025, Chinese AI company DeepSeek made its latest AI model, DeepSeek-R1 come out, which took the AI world by surprise. The model can perform the same tasks as other top models, but at a lower cost. Unlike other AI models, DeepSeek-R1 is free to use, making it easy for developers to study and build upon. DeepSeek-R1 is very good at tasks that need logical inference (逻辑推理) and real-time decision-making. Whether it’s solving difficult maths problems or breaking down other scientific questions, DeepSeek-R1’s special system allows it to improve its thinking and problem-solving abilities over time. On its first day online, over 19,000 programmers started projects to study it and most thought highly of it. Even a top scientist from Meta (a famous US tech company) praised it, saying, “This kind of free AI could change the world.” The rise of DeepSeek has also brought its founder, Liang Wenfeng, into the spotlight (聚光灯). Born in 1985 in a small town in Guangdong Province, Liang was greatly influenced by his parents who were both primary school teachers. Even though there was little information, Liang showed an amazing talent for maths and a great love for technology from a young age. In university, he developed a strong interest in machine learning, which was helpful for his future achievements. In 2023, Liang founded DeepSeek in Hangzhou. He has put together a talented team. So far, they’ve developed several AI models. DeepSeek is changing the AI industry. It proves that China isn’t just catching up with the West in technology—it’s setting new rules for the game. 1.

Passage 9 In many countries, students begin learning English as early as kindergarten. Yet by high school, only a small percentage achieve fluency. What makes the difference? A recent report from the Educational Testing Service identified three key factors that predict success: consistent exposure, active usage, and emotional connection. Consistent exposure means more than sitting in a classroom. Top learners surround themselves with the language—they change their phone settings, listen to English podcasts during commutes, and read news in English daily. This constant immersion trains the ear to recognize speech patterns naturally. One 16-year-old from Beijing reported that after watching every episode of a popular American sitcom three times, she no longer needed Chinese subtitles. Active usage pushes learners beyond passive reception. Instead of consuming content, they produce it—writing journals, recording voice memos, or participating in online debates. A study from the University of Cambridge showed that students who practiced speaking for at least 15 minutes daily improved their oral fluency 3 times faster than those who only listened. Importantly, these learners weren’t afraid of sounding imperfect; they embraced the discomfort of not knowing every word. The third factor, emotional connection, is often ignored. Students who link English to personal passions—gaming, music, or even cooking videos—develop deeper motivation. Take 14-year-old Maria from Mexico, who learned English by translating her favorite pop songs. “I didn’t feel like I was studying,” she says. “I was unlocking lyrics I loved.” This positive association turns a challenging task into a rewarding hobby, making persistence feel effortless. 根据短文内容，选择最佳答案。 1. According to the passage, how many students achieve English fluency? A．Most students do. B．About half of them. C．Only a small number. D．Almost all students. 2. What did the 16-year-old from Beijing do to improve her English? A．She traveled to an English-speaking country. B．She watched a sitcom repeatedly until she understood it well. C．She took extra classes after school every day. D．She practiced speaking English for 15 minutes daily. 3. What does the University of Cambridge study suggest about speaking practice? A．Listening alone is more effective than speaking. B．Daily speaking practice significantly improves oral fluency. C．Speaking practice only helps advanced learners. D．15 minutes of speaking weekly is sufficient. 4. How did Maria from Mexico learn English? A．By attending a language school. B．By translating her favorite songs. C．By reading English novels. D．By practicing with native speakers. 5. What is the author’s main purpose in writing this passage? A．To show that learning English is impossible for most students. B．To recommend three effective strategies for language learning. C．To prove that emotional connection is the only factor that matters. D．To describe the teaching methods of different countries. Passage 10 In 2019, the brand-new 520-kilometer Kisumu-Eldoret railway was completed and opened. Before its birth, the only transport ways connecting Kisumu, Uganda’s main lake port, and Eldoret, Kenya’s inland capital city, were bumpy country roads and an old railway track built in 1905. The outdated trains ran at a very low speed. It would take 11 hours to travel from Kisumu to Eldoret by the old train. Luckily, this new railway built with Chinese aid has already shortened the passenger travel time between the two cities to nearly three hours. At present, more than 1.8 million passengers take this railway every single year. Local Ugandan residents gain plenty of advantages from this new railway. A local civil servant shared, “I’m really satisfied with the railway built by our Chinese partners. Great changes have taken place in our small town these years, and all the villagers here live a wealthier life.” A local trader added, “I’ve taken this new train many times since 2019, and the experience is wonderful. It’s cheap and super convenient. I can reach business sites on schedule and finish trade deals without trouble.” The railway also makes transporting fresh food much easier.

Passage 12 The 480-kilometer Mombasa-Nairobi Standard Gauge Railway was put into service in 2017 with China’s technical and financial support.
